1. MAJOR CHANGES IN FUEL SYSTEM OF D27DTP (POWER

UP) ENGINE
There are some changes in the parts related to the fuel system due to the newly adopted
D27DTP (POWER UP) engine. The major changes are as follows. Refer to the next pages for
further details.

1) Injector
Two nozzle holes are added (currently 7)
D27DTP & D27DT (EU IV)
to the tip of the injector to increase the
amount of fuel injection and to improve
injection efficiency according to the
increased engine power.
The existing C2I coding (16 digits) is
changed to C3I coding (20 digits) to
monitor fuel injection and follow the target
value.
For the D27DT engine, the injector MDP
D27DT (minumum current for the solenoid in the
injector to lift the nozzle) is leaned only
when the engine is running. However, for
the D27DTP engine, it is learned when the
vehicle is in motion and the engine is at
idle speed.
2) Common Rail

D27DTP & D27DT (EU IV) The orifice is added to the connection to
the fuel pipe of the HP pump to prevent
the fuel pulsation by the fuel supply and
fuel cut according to the increase of
injected fuel volume. (It is also installed on
the connection of the high pressure fuel
supply line of the HP pump.)

3) Fuel Rail - Chrome Color

The I.D and O.D of the fuel rail between
D27DTP & D27DT (EU IV)
HP pump and common rail are increased
according to the increased amount of fuel
injection.
Also, the engine ECU, HFM sensor and

1. INTAKE SYSTEM LAYOUT

The intake system for the D27DTP (POWER UP) engine is equipped with the throttle body that has
a flap to block the air coming to the engine when the engine is switched off. Therefore, the
structure of the intake manifold has been changed.
Also, the improved HFM sensor (from HFM5.0 to HFM6.0) has been installed to control the intake
air precisely so that the NOx in the exhaust gas can be decreased.
 1792-01

1. COMPONENTS
The components of the exhaust system for the D27DTP (POWER UP) engine have been changed
as follows:
1. E-EGR valve: Controlling the EGR valve electrically and sends the valve location signal to
ECU (vacuum modulator control has been deleted)
2. EGR cooler: Decreasing EGR gas (NOx) efficiently by cooling the EGR gas and let it flow to
the intake pipe
3. VGT turbocharger: Increase in capacity and performance compared to D27DTP & D20DT
engine
The EGR system has been changed to control NOx more efficiently and the VGT turbo charger
has been changed to increase the engine power. For more details, refer to the next description.
The exhaust system for D27DTP (POWER UP) engine is as follows:

1. OVERVIEW FOR CDPF (EURO IV)

1) General Description
The CDPF (Catalyst & Diesel Particulate Filter) was installed to the Rexton II D27DTP engine
previously. However, it is now installed to the all 2009 DI engine models, except the Actyon
Sports. The DI engine types installed to Rexton are D27DTP, D27DT and D20DT, and their CDPF,
related sensor and operation logic are the same.
This section describes the CDPF system (based on Euro IV) which is installed to the Rexton II
D27DTP engine (older model).

2) Compatibility of CDPF System by Vehicle Model

Rexton II: Same CDPF system for D27DTP and D27DT engines (including its components)
Kyron & Actyon: Same CDPF system for D27DT and D20DT engines (including its components)

- The CDPF assemblies installed to the Euro IV D27DTP Rexton II and 2009 Rexton II are
different in their mounting layout, but their front/rear exhaust temperature sensors and
differential pressure sensors are same.

3) System Met with Euro IV Regulations

- E-EGR valve
- EGR cooler
- Engine ECU (Ver. 3.2)
- HFM sensor
- C3I injector
- Electronic throttle valve (body)
- Other engine mounting components
For details about the modified components and system related to the Euro IV regulations, refer to
the 2008 Rodius engine service manual.
2. CDPF(EURO IV) SYSTEM
The CDPF system is only installed to the D27DT engine, and the major changes comparing to the
previous D27DT engine is as follows:

CDPF (Catalyst & Diesel Particulate Filter) and sensors

compartment

As the soot is filtered in the CDPF, the pressure between the front side and the rear side of the
filter is different from each other. If the amount of soot is over 28 g, the soot is burnt in the
CDPF. The combustion is determined depending on the pressure difference, temperature of
exhaust gas and EGR ratio. According to these, the soot filtered by post injection of injector is
burnt at

 2412-02

Throttle Body

CDPF system controls the amount of intake air by

controlling the electronic throttle body. The electronic
throttle body has the following main functions.
CDPF control- added a function that increases the
exhaust gas temperature by closing the throttle valve
flap to minimize the intake air amount by the fuel
injection amount during the CDPF regeneration range
with the low engine load range.
ON/OFF control - prevents the engine from turning off
with vibration and noise by closing the throttle body flap
to block the intake air when the engine is stopped.
Duty control- controls the valve inside the throttle body
to burn more EGR gas in the EGR valve operating range.

VGT Turbocharger and Front Exhaust Gas Temperature Sensor

Turbocharger may become weaker if high Front exhaust gas

temperature exhaust gas passes through the temperature sensor
turbocharger for DPF regeneration process.
The front exhaust gas temperature sensor monitors
the temperature of the exhaust gas that flows into
the turbocharger.
If the temperature of the exhaust gas that passes
through the exhaust manifold is higher than the
specification, the ECU decreases the fuel injection
amount and increases the EGR gas intake amount
to decrease the exhaust gas temperature.
1. OVERVIEW
As the solution for environmental regulations and PM
(Particla Material) of diesel engine, the low emission
vehicle is getting popular. This vehicle is equipped with an
extra filter to collect the soot and burn it again so that the
amount of PM in the exhaust gas passed through the
DOC (Diesel Oxydation Catalyst) is reduced. The CDPF
(Catalyst & Diesel Particulate Filter) is an integrated filter
including DOC (Diesel Oxydation Catalyst) and DPF
(Diesel Particulate Filter).

Regulated parts are carbon monoxide (CO), nitrogen oxide (NOx), particular matter (PM) and soot
in the exhaust emission, and the particulars of the regulations are prescribed in the following table.
 2412-02

2. CDPF (EURO IV) SYSTEM CONTROL

1) Combustion Temperature and Procedures
As the soot is filtered in the CDPF, it is burnt and removed, and the CDPF is returned to the initial
state to collect the soot. Therefore, the burning procedures in the CDPF can be called as
regeneration.
The CDPF assembly is integrated with DOC (at front side) and DPF (at rear side).
The DPF burns the soot with high-temperature exhaust gas (over The rear exhaust gas
temperature sensor monitors the temperature of DPF section. If this temperature is below the
regeneration temperature, the ECU increases the post injection period to increase the fuel
injection amount, and consequently to increase the exhaust gas temperature.

Front exhaust gas temperature sensor

(Measuring temperature of exhaust gas in
exhaust manifold)

Rear exhaust gas temperature sensor

(Measuring temperature of exhaust gas escaping DOC)

- Normally, when the vehicle is driven for 600 ~ 1,200 km, the enough amount of soot to be
burnt is filtered and accumulated in the CDPF. The ECU increase the amount of post
injection to increase the tempeature of exhaust gas up to so that the soot is burnt.
The soot is burnt for 15 ~ 20 minutes.
2) Sytem composition for Soot Combustion
When the engine is running in low load range, the temperature of exhaust gas is decreased as the
amount of fuel supplied is decreased. To burn the soot filtered in the CDPF, the control system
should be installed to check the operating range and increase the temperature of exhaust gas by
controlling the amount of fuel supplied and intake air.
Two temperature sensors and one differential pressure sensor monitor the CDPF's operating
range. According to these sensors' information, the throttle flap decreases the intake air entered
to the throttle body. Also, the fuel injection pattern is added to increase the temperature of
exhaust gas for soot combustion.
There are three fuel injection patterns (pilot injection, pre-injection and main injection). As the
CDPF is installed, the post injection pattern is added.

3) Post Injection and Air Mass Control

When the differential pressure sensor detects the pressure difference between the front and the
rear side of CDPF, the sensor sends signal indicating the soot is acumulated and the post
injection is performed to raise the temperature of exhaust gas. The amount of fuel injected is
determined according to the temperature of exhaust gas detected by the rear temperature sensor.
If the temperature is below the amount of fuel injected is increased to raise the
temperature. If the temperature is over the amount of fuel injected is decreased or not
controlled.
When the engine is running in low load range, the amount of post injection and the amount of
intake air are controlled. It is to raise the temperature by increasing the amount of fuel while
decreasing the amount of intake air.
 2412-02

Throttle bodies by engine type

- The throttle valve is controlled by electric signals sent from the engine ECU for optimal
fuel injection volume, engine load and effective combustion of EGR gas according to
the Euro 4 regulations. It has following functions by the engine type.
3. SOOT FILTERING AND BURNING PROCEDURES
1) Operating Procedures of CDPF
The most efficient and practical technology for now is adopted to the diesel particulate filter
(DPF).
This system collects the soot from the diesel engine to the filter and burns the soot so that over
than 95% of soot can be removed from the exhaust gas. However, the durability and the cost of
additional system remain as problems.
Firstly, the exhaust gas is passed through the DOC and its temperature is increased as it is
oxidized. The ECU detects the temperature change with two temperature sensors. The CO, HC
and partial particulate material are removed from the exhaust gas (this procedures are the sames
as the ones for the conventional DOC and no sensor is required).

After the exhaust gas is passed through the DOC and oxidized, most of the harmful material is
removed from the exhaust gas. However, to meet the environmental regulations in the future, the
soot is filtered and burnt again in DPF to decrease the particulate material further.

Rear exhaust gas temperature sensor

(Measuring temperature of exhaust gas
escaping DOC)

- The filtered soot is burned whenever the vehicle is driven for 600 ~ 1200 km. The driving
distance can be differed depending on the vehicle's driving conditions. The soot is burnt
for 15 ~ 20 minutes.

2) Fuel Injection During CDPF Regeneration

3) Warning Lamp Related To CDPF

The CDPF system enters the regeneration mode when

the driving distance becomes approx. 600 to 1,200 km
(may differ by the driving condition and driving style).
Then, the engine ECU performs the CDPF regeneration
operation. However, the driver is not informed with this
operation by any engine warning lamp or vehicle
signal, so he/she may not detect this operation. The
control logic at the post-injection during the
regeneration process is to increase the fuel injection
volume and control the intake air volume (by the throttle
No illuminating
body) in order to increase the temperature of the
exhaust gas. The driver may not feel any particular
difference from the vehicle.
 2412-02

1. If the CDPF cannot reach the regeneration

temperature due to low speed driving or other
reason during the regeneration process, the soot
is continuously accumulated in the CDPF. When
this condition continues and the CDPF is
overloaded with soot, the engine warning lamp
blinks to inform this situation to the driver.
2. In order to solve this problem, drive the vehicle at a
speed of approx. 80 km/h for 15 to 20 minutes to
perform the CDPF regeneration process.
3. If the engine warning lamp on the instrument
Blinking cluster blinks, the CDPF is overloaded. In this
case, perform the step 2.

1. If the vehicle is driven at a speed of 5 to 10 km/h

for an extended period of time, the soot
accumulated in the CDPF cannot be burnt as the
CDPF cannot reach the regeneration
temperature. Then, an excessive amount of soot
can be accumulated in the CDPF.
2. This case is much worse than the simple
overload of the CDPF. To inform this to the
driver, the engine warning lamp comes on and
the engine power is decreased to protect the
system.
Illuminating 3. To solve this problem, blow soot between the
engine and exhaust system several times and
erase the related DTC. Then, check if the same
DTC is regenerated again. If so, check the DTC
related to the differential pressure sensor.

Actually, the DTC for the CDPF is generated more often by the component related to the CDPF
system, such as the differential pressure sensor, than by excessive soot in the CDPF.

1. SYSTEM DESCRIPTION
1) System Description

The cruise control is an automatic speed control system that maintains a desired driving speed
without using the accelerator pedal.
The vehicle speed must be greater than 38 km/h to engage the cruise control. This feature is
especially useful for motorway driving.

The cruise control system is a supplementary system, which helps the driver to drive the vehicle
at a desired speed without using the accelerator pedal under the traffic condition where the
vehicle-to-vehicle distance meets the legal requirement.
2) Traffic Conditions for Using Cruise Control
Use the cruise control system only when the traffic is not jammed, driving on motorways or
highways where there is no sudden change in the driving condition due to traffic lights, pedestrian,
etc.

Improper use of the cruise control could be dangerous.

- Do not use on winding roadsyy .
- Do not use in heavy traffic.
- Do not use on slippery, wet roads.
This could result in a loss of control, collision, and/or personal injuries.
 8510-23

2. CONFIGURATION
1) Circuit Diagram

The engine ECU detects the operating conditions of cruise control system, and monitors the
braking performance, vehicle speed, road conditions and ESP system operation. If the engine
ECU determines that there are not any problem to drive in cruise control mode, the vehicle can be
operated by cruise switch signals (decelerating, accelerating, cruising).

3. OPERATION
1) Setting a Desired Speed

1. To operate the cruise control, accelerate to the desired speed, which must be more than 36
km/h and less than 150 km/h.
2. When the desired speed is reached, push up the ACCEL switch of the cruise control lever or
push down the DECEL switch for 1 second per one switching and then release the accelerator
pedal slowly.
3. Now, the vehicle is cruised by this system with the set speed. You don't need to use the
accelerator pedal.
4. Refer to the following pages for details of operation.

Never use the cruise control system until you get used to it.
Improper use or not fully aware of this function could result in collision and/or personal injuries.
2) Accelerating with the Cruise Control System

(1) While the cruise control system is running

1. Push up the ACCEL switch of the cruise control lever and hold it until the desired speed is
reached without an accelerator pedal intervention.
2. When the desired speed is reached, release the lever.

(2) When the cruise control system is not running

To increase the speed with the cruise control system while the system is not running, follow the
procedures below.

1. Accelerate using the accelerator pedal over 36 km/h.

2. Push up the ACCEL switch of the cruise control lever and hold it. And then release the
accelerator pedal slowly.
3. When the desired speed is reached, release the lever.

(3) Tap-up while the cruise control system is running

To increase the vehicle speed in stages while the cruise control system is running, follow the
procedures below.

1. Push up the ACCEL switch of the cruise control lever less than 0.5 second per one switching
while the cruise control system is running. This is a tap-up switching. When you operate a tap-
up switching, the vehicle is accelerated for 1.3 km/h over the previous set speed.
2. If you want to accelerate for 13 km/h, operate the tap-up switching ten times without
accelerating with the cruise control system.
 8510-23

3) Decelerating with the Cruise Control System

(1) While the cruise control system is running

1. Push down the DECEL switch of the cruise control lever and hold it until the desired speed is
reached without a brake pedal intervention. But the cruise control system cannot maintain the
cruise function at less than 34 km/h.
2. When the desired speed is reached, release the lever.

(2) When the cruise control system is not running

To decrease the vehicle speed with the cruise control system when the system is not running,
follow the procedures below.
1. Push down the cruise control switch lever to DECEL side and hold it until the desired speed is
reached while the vehicle speed is over 36 km/h.
2. And then release the accelerator pedal slowly.
3. When the desired speed is reached, release the lever. But the cruise control system cannot
maintain the cruise function at less than 34 km/h.

(3) Tap-down while the cruise control system is running

To decrease the vehicle speed in stages while the cruise control system is running, follow the
procedures below.
1. Push down the DECEL switch of the cruise control lever less than 0.5 second per one switching
while the cruise control system is running. This is a tap-down switching. When you operate a
tap-down switching, the vehicle is decelerated for 1.0 km/h below the previous set speed.
If you want to decelerate for 10 km/h, operate the tap-down switching ten times without the
2. brake pedal intervention.
4) Recovery of Set Speed (RESUME)

Even if the cruise control is cancelled, the previous set cruise speed can be recovered by pulling
up the cruise control lever when the current vehicle speed is over 36 km/h without an acceleration
intervention. But if you turn off the ignition switch, the memorized set speed is cleared and you
cannot recover the previous set speed.

But the driver should know the previous set speed to react to the changed vehicle speed
properly. If the vehicle speed increases abruptly, depress the brake pedal to adjust the vehicle
speed properly.
 8510-23

5) Normal Cancellation of the Cruise Control

The cruise control system will be canceled when one or more items of the following conditions
are applied;

1. When the brake pedal is depressed or When ESP is activated.

2. When the cruising speed is downed less than 34 km/h
3. When applying the parking brake during driving.
4. When using the clutch in order to shift (M/T only).

Keep the main cruise control switch in the neutral position when not using the cruise control.
(1) Abnormal Cancellation of the Cruise Control
1. When the rapid deceleration is applied without braking.
When the rapid acceleration is applied without acceleration pedal intervention.
2. When the cruise control lever is faulty.
3. When the brake switch and the brake light switch input signal are implausible.

When the cruise control function is cancelled abnormally or intermittent problems occur, stop the
vehicle and turn off the ignition switch and remove the key to reset the system. After a while, turn
on the ignition switch again to operate the cruise control system.

1. Do not move the shift lever to Neutral position while driving with the cruise control turned on.
Otherwise, it may result in system malfunction or accidents.
2. Always be prepared to use the brake or accelerator pedal for safe driving while the cruise
control system is running.
3. The actual speed can be different from the set speed momentarily when driving on a uphill
or downhill. So, it is recommended to disable the cruise control function on a uphill or
downhill. hen driving on a steep hill use the engine brake and foot brake properly to protect
the vehicle system and for a safe driving.
4. Ensure that the safe distance is maintained and use the brake pedal if needed.

2. DESCRIPTION AND OPERATION

1) Cleanliness and Care
An automobile engine is a combination of many machined, honed, polished and lapped surfaces with
tolerances that are measured in the ten-thousanths of an inch. When any internal engine parts are
serviced, care and cleanliness are important. A liberal coating of enigne oil should be applied to friction
areas during assembly, to protect and lubricate the surfaces on initial operation.
Proper cleaning and protection of machined surfaces and friction areas is part of the repair procedure.
This is considered standard shop practice even if not specifically stated.
Whenever valve train components are removed for service, they should be kept in order.
They should be installed in the same locations, and with the same mating surfaces, as when they were
removed. Battery cables should be disconnected before any major work is performed on the engine.
Failure to disconnect cables may result in damage to wire harness or other electrical parts.

2) On-Engine Service

- Disconnect the negative battery cable before removing or installing any electrical unit, or when a
tool or equipment could easily come in contact with exposed electrical terminals.
Disconnecting this cable will help prevent personal injury and damage to the vehicle.
The ignition must also be in LOCK unless otherwise noted.
Notice Any time the air cleaner is removed, the intake opening

- Any time the air cleaner is removed, the intake opening should be covered. This will protect
against accidental entrance of foreign material, which could follow the intake passage into the
cylinder and cause extensive damage when the engine is started.g

1. FUEL SYSTEM SPECIFICATION

Use Only Unleaded Fuel Rated at 89 Octane or Higher

Fuel quality and additives contained in fuel have a significant effect on power output, drivability, and life
of theengine. Fuel with too low an octane number can cause engine knock.

Do Not Use Methanol

Fuels containing methanol (wood alcohol) should not be used in vehicle.

This type of fuel can reduce vehicle performance and damage components of the fuel system.

Vehicle Fueling from Drums or Storage Containers

For safety reasons (particularly when using noncommercial fueling systems) fuel containers, pumps and
hoses must be properly earthed. Static electricity build up can occur under certain atmospheric and fuel
flow conditions if unearthed hoses, particularly plastic, are fitted to the fuel-dispensing pump.
It is therefore recommended that earthed pumps with integrally earthed hoses be used, and that
storage containers be properly earthed during all noncommercial fueling operations.

1. OVERVIEW OF EXHAUST SYSTEM

- When you are inspecting or replacing exhaust system components, make sure there is adequate
clearance from all points on the underbody to avoid possible overheating of the floor panel and
possible damage to the passenger compartment insulation and trim materials.
Check the complete exhaust system and the nearby body areas and trunk lid for broken, damaged,
missing or mispositioned parts, open seams, holes, loose connections, or other deterioration which
could permit exhaust fumes to seep into the trunk may be an indication of a problem in one of these
areas. Any defects should be corrected immediately.

2. OVERVIEW OF MUFFLER
Aside from the exhaust manifold connection, the exhaust system uses a flange and seal joint design
rather than a slip joint coupling design with clamp and U-bolts.
If hole, open seams, or any deterioration is discovered upon inspection of the front muffler and pipe
assembly, the complete assembly should be replace, the complete assembly should be replaced.
The same procedure is applicable to the rear muffler assembly. Heat shields for the front and rear
muffler assembly and catalytic converter protect the vehicle and the environment from the high
temperatures that the exhaust system develops.

3. OVERVIEW OF CATALYTIC CONVERTER

- When jacking or lifting the vehicle from the body side rails, be certain that the lift pads do not
contact the catalytic converter, as this could damage the catalytic converter.

- Use of anything other than unleaded fuel will damage the catalyst in the catalytic converter.
The catalytic converter are emission-control devices added to the exhaust system to reduce
pollutants from the exhaust pipes.
The oxidation catalyst is coated with a catalytic material containing platinum and palladium,
which reduces levels of hydrocarbon (HC) and carbon monoxide (CO) from the exhaust gas.
The three-way catalyst has coatings which contain platinum and rhodium, which additionally
lower the levels of oxides of nitrogen (NOx).

1. GENERAL DESCRIPTION
The cooling system maintains the engine temperature at an efficient level during all engine operating
conditions. When the engine is cold, the cooling system cools the engine slowly or not at all. This slow
cooling of the engine allows the engine to warm up quickly. The cooling system includes a radiator and
recovery subsystem, cooling fans, a thermostat and housing, a water pump, and a water pump drive
belt. The timing belt drives the water pump. All components must function properly for the cooling
system to operation. The water pump draws the coolant from the radiator.
The coolant then circulates through water jackets in the engine block, the intake manifold, and the
cylinder head. When the coolant reaches the operating temperature of the thermostat, the thermostat
opens. The coolant then goes back to the radiator where it cools. This system directs some coolant
through the hoses to the heat core. This provides for heating and defrosting. The coolant reservoir is
connected to the radiator to recover the coolant displaced by expansion from the high temperatures.
The coolant reservoir maintains the correct coolant level. The cooling system for this vehicle has no
radiator cap or filler neck. The coolant is added to the cooling system through the coolant reservoir.

1. CHARGING SYSTEM OPERATION

Alternators use a new type of regulator that incorpo-rates a diode trio. A Delta stator, a rectifier bridge,
and a rotor with slip rings and brushes are electrically similar to earlier alternators.
A conventional pulley and fan are used. There is no test hole.

1) Charging Time Required

The time required to charge a battery will vary depending upon the following factors:
Size of Battery
- A Completely discharged large heavy-duty battery required more than twice the recharging time
as a completely discharged small passenger car battery.
Temperature
- A longer time will be needed to charge any battery at than at
When a fast charger is connected to a cold battery, the current accepted by the battery will be
very low at first. The battery will accept a higher current rate as the battery warms.

Charger Capacity
- A charger which can supply only 5 amperes will require a much longer charging period than a
charger that can supply 30 amperes or more.

State-of-Charge
- A completely discharged battery requires more than twice as much charge as a onehalf charged
battery. Because the electrolyte is nearly pure water and a poor conductor in a completely
discharged battery, the current accepted by the battery is very low at first. Later, as the charging
current causes the electrolyte acid content to increase, the charging current will likewise
increase.

2. STARTING SYSTEM OPERATION

The engine electrical system includes the battery, the ignition, the starter, the alternator, and all the
related wiring. Diagnostic tables will aid in troubleshooting system faults. When a fault is traced to a
particular component, refer to that component section of the service manual. The starting system circuit
consists of the battery, the starter motor, the ignition switch, and all the related electrical wiring. All of
these components are connected electrically.
3. IGNITION SYSTEM OPERATION
This ignition system does not use a conventional distributor and coil. It uses a crankshaft position sensor
input to the Engine Control Module (ECM).
The ECM then determines Electronic Spark Timing (EST) and triggers the electronic ignition system
ignition coil.
This type of distributorless ignition system uses a "waste spark" method of spark distribution. Each
cylinder is paired with the cylinder that is opposite it (2.3L DOHC: 2 - 3 or 1 - 4, 3.2L DOHC: 1 - 6 or 2 - 5
or 3 - 4).
The spark occurs simultaneously in the cylinder coming up on the compression stroke and in the
cylinder coming up on the exhaust stroke.
The cylinder on the exhaust stroke requires very little of the available energy to fire the spark plug.
The remaining energy is available to the spark plug in the cylinder on the compression stroke. These
systems use the EST signal from the ECM to control the EST.
The ECM uses the following information: Engine load (mass air flow sensor, manifold air pressure
sensor).

Engine coolant temperature.

Intake air temperature.
Crankshaft position.
Engine speed (rpm).

1) Electronic Ignition System Ignition Coil

The Electronic Ignition (EI) system ignition coil is located on the cylinder head cover.
The double ended coils re ceive the signal for the ECM which controls the spark advance. Each EI
system ignition coil provides the high voltage to two spark plugs simultaneously;
3.2L DOHC
T1/1: cylinder 2 and 5
T1/2: cylinder 3 and 4
T1/3: cylinder 1 and 6
The EI system ignition coil is not serviceable and must be replaced as an assembly.

1. SYSTEM DESCRIPTION
1) System Description

The cruise control is an automatic speed control system that maintains a desired driving speed without
using the accelerator pedal.
The vehicle speed must be greater than 38 km/h to engage the cruise control. This feature is especially
useful for motorway driving.

The cruise control system is a supplementary system, which helps the driver to drive the vehicle at a
desired speed without using the accelerator pedal under the traffic condition where the vehicle-to-
vehicle distance meets the legal requirement.
2) Traffic Conditions for Using Cruise Control
Use the cruise control system only when the traffic is not jammed, driving on motorways or highways
where there is no sudden change in the driving condition due to traffic lights, pedestrian, etc.

Improper use of the cruise control could be dangerous.

- Do not use on winding roadsyy .
- Do not use in heavy traffic.
- Do not use on slippery, wet roads.
This could result in a loss of control, collision, and/or personal injuries.
 8510-23

2. CONFIGURATION
1) Circuit Diagram

The engine ECU detects the operating conditions of cruise control system, and monitors the braking
performance, vehicle speed, road conditions and ESP system operation. If the engine ECU determines
that there are not any problem to drive in cruise control mode, the vehicle can be operated by cruise
switch signals (decelerating, accelerating, cruising).

 8510-23

3. OPERATION
1) Setting a Desired Speed

1. To operate the cruise control, accelerate to the desired speed, which must be more than 36 km/h and
less than 150 km/h.
2. When the desired speed is reached, push up the ACCEL switch of the cruise control lever or push
down the DECEL switch for 1 second per one switching and then release the accelerator pedal slowly.
Now, the vehicle is cruised by this system with the set speed. You don't need to use the accelerator
3. pedal.
Refer to the following pages for details of operation.
4.

Never use the cruise control system until you get used to it.
Improper use or not fully aware of this function could result in collision and/or personal injuries.
2) Accelerating with the Cruise Control System

(1) While the cruise control system is running

1. Push up the ACCEL switch of the cruise control lever and hold it until the desired speed is reached
without an accelerator pedal intervention.
2. When the desired speed is reached, release the lever.

(2) When the cruise control system is not running

To increase the speed with the cruise control system while the system is not running, follow the
procedures below.

1. Accelerate using the accelerator pedal over 36 km/h.

2. Push up the ACCEL switch of the cruise control lever and hold it. And then release the accelerator
pedal slowly.
3. When the desired speed is reached, release the lever.

(3) Tap-up while the cruise control system is running

To increase the vehicle speed in stages while the cruise control system is running, follow the procedures
below.

1. Push up the ACCEL switch of the cruise control lever less than 0.5 second per one switching while
the cruise control system is running. This is a tap-up switching. When you operate a tap-up switching,
the vehicle is accelerated for 1.3 km/h over the previous set speed.
2. If you want to accelerate for 13 km/h, operate the tap-up switching ten times without accelerating with
the cruise control system.
 8510-23

3) Decelerating with the Cruise Control System

(1) While the cruise control system is running

1. Push down the DECEL switch of the cruise control lever and hold it until the desired speed is reached
without a brake pedal intervention. But the cruise control system cannot maintain the cruise function at
less than 34 km/h.
2. When the desired speed is reached, release the lever.

(2) When the cruise control system is not running

To decrease the vehicle speed with the cruise control system when the system is not running, follow the
procedures below.
1. Push down the cruise control switch lever to DECEL side and hold it until the desired speed is
reached while the vehicle speed is over 36 km/h.
2. And then release the accelerator pedal slowly.
3. When the desired speed is reached, release the lever. But the cruise control system cannot maintain
the cruise function at less than 34 km/h.

(3) Tap-down while the cruise control system is running

To decrease the vehicle speed in stages while the cruise control system is running, follow the
procedures below.
1. Push down the DECEL switch of the cruise control lever less than 0.5 second per one switching while
the cruise control system is running. This is a tap-down switching. When you operate a tap-down
switching, the vehicle is decelerated for 1.0 km/h below the previous set speed.
If you want to decelerate for 10 km/h, operate the tap-down switching ten times without the brake pedal
2. intervention.
4) Recovery of Set Speed (RESUME)

Even if the cruise control is cancelled, the previous set cruise speed can be recovered by pulling up the
cruise control lever when the current vehicle speed is over 36 km/h without an acceleration intervention.
But if you turn off the ignition switch, the memorized set speed is cleared and you cannot recover the
previous set speed.

But the driver should know the previous set speed to react to the changed vehicle speed properly. If the
vehicle speed increases abruptly, depress the brake pedal to adjust the vehicle speed properly.
 8510-23

5) Normal Cancellation of the Cruise Control

The cruise control system will be canceled when one or more items of the following conditions are
applied;

1. When the brake pedal is depressed or When ESP is activated.

2. When the cruising speed is downed less than 34 km/h
3. When applying the parking brake during driving.
4. When using the clutch in order to shift (M/T only).

Keep the main cruise control switch in the neutral position when not using the cruise control.
(1) Abnormal Cancellation of the Cruise Control
1. When the rapid deceleration is applied without braking.
When the rapid acceleration is applied without acceleration pedal intervention.
2. When the cruise control lever is faulty.
3. When the brake switch and the brake light switch input signal are implausible.

When the cruise control function is cancelled abnormally or intermittent problems occur, stop the vehicle
and turn off the ignition switch and remove the key to reset the system. After a while, turn on the ignition
switch again to operate the cruise control system.

1. Do not move the shift lever to Neutral position while driving with the cruise control turned on.
Otherwise, it may result in system malfunction or accidents.
2. Always be prepared to use the brake or accelerator pedal for safe driving while the cruise control
system is running.
3. The actual speed can be different from the set speed momentarily when driving on a uphill or
downhill. So, it is recommended to disable the cruise control function on a uphill or downhill. hen
driving on a steep hill use the engine brake and foot brake properly to protect the vehicle system
and for a safe driving.
4. Ensure that the safe distance is maintained and use the brake pedal if needed.

1. CAUTIONS WHEN WORKING ON ELECTRICAL UNITS

- Disconnect the negative cable from the battery
in advance when working on electrical units.

Make sure to turn "OFF" the ignition switch

and other lamp switches before
disconnecting or connecting the negative
battery cable. (Otherwise, semiconductor
parts can be damaged.)

- Do not drop or appy excessive impact to

sensors and relays.

- If a fuse is blown, replace it with a fuse which

has the correct amperage rating. If you use a
fuse with higher capacity than the
specification, the component can be damaged
or catch fire.

10A 15A
- Make sure a connector is connected securely.
Loose connection results in malfunction.

- When disconnecting a connector equipped with a

lock, press it down to the direction in the below
figure.

- When checking voltage or continuity of the

connector terminal with a circuit tester,
connect the tester probe to the terminal at the
harness side. For a sealed type connector,
connect the probe to the terminal through the
hole in the rubber cap of the wiring. Take care
not to damage the insulation of the wires.
Insert the probe until it contacts the terminal
completely.

When inspecting the airbag system, make

sure to use a diagnostic device, not a circuit
tester.
 8410-00

2. CHECKING CABLES AND WIRES

- Check for loose connection or rust.
- Check terminals and wires for corrosion due to electrolyte leakage.
- Check terminals and wires for open circuit.
- Check the wire insulation and coat for damage, cracks or deterioration.
- Check if the conductive parts of the terminals do not contact with vehicle body or other metal parts.
Check that the grounding part has continuity with mounting bolts and vehicle body.
- Check that wires are properly routed.
- Make sure that wires are securely fixed to avoid contact with sharp body parts and high-temperature
- parts, such as the exhaust manifold and exhaust pipes.
The rotating parts, such as fan pulley and fan belt, perturbative parts and wiring should be secured
- tightly at regular intervals.
Secure the wiring between the fixed parts, such as the vehicle body, and vibrating parts, such as the
- engine, after slackening it slightly to prevent it from being damaged.

Symptom 1: There is no signal wiping in AUTO mode.

1. The windshield wiper should operate one wiping cycle when the engine is started with the wiper
switch in AUTO.
2. The windshield wiper should operate one wiping cycle when the wiper switch is turned to AUTO
from OFF. However, this cannot be done after first operation, if it is not raining. The wiper system
regards the additional 5 minutes after raining as the raining period. Thus, the signal wiping should
be performed even in this period. If this fails, check the pin number 12 (B+) in connector. If the pin
is not defective, check the wiper relay terminals.

Symptom 2: No wiper operation with the wiper switch in AUTO position

1. Check the operation mode of wiper switch.

2. Check the power supply (pin number 3: Ground, pin number 4: IGN) to sensor.
3. Check the wiper relay.

Symptom 3: Abrupt wiper operation (3~4 times) at high speed

If the wiping speed control knob is positioned at FAST position, this may happen because the sensitivity
in FAST mode is extremely high. In that case, move the knob to another position.

Symptom 4: Continuous operation on dry windshield

1. Check if the wiper blade is worn. This symptom may happen when the wiper cannot sweep the whole
wiping range completely. If the wiper blade is worn, replace it with new one.
2. If the wiping speed control knob is positioned at FAST position, this may happen because the
sensitivity in FAST mode is extremely high. In that case, move the knob to another position.

Symptom 5: Too slow or fast wiping operation

Check the wiper operation mode. If the wiping speed control knob is FAST or SLOW position, adjust it to
medium speed mode.
1. The tail lamps and headlamps can be controlled by the communication with the rain sensor only
when the auto light switch is in "AUTO" position with the ignition switch "ON".

2. Rain detected headlamp: If it rains heavy which requires the highest AUTO speed, the headlamps
are turned on automatically (while the light switch is in "AUTO" position and the wiper switch is in
"AUTO" position).
3. Night detected wiping: When the auto light control turns on the headlamps and the rain sensor
detects the rain, the wiper sensitivity is automatically increased by one level. (i.e. the AUTO wiper
switch is at the 3rd level, but the wiper operates at the 4th level.)

 Speed Sensitive AUTO Wiper
For RKSTICS without the rain sensor, perform the following operation:
1. Controls the wiper intermittent operation by the values from the vehicle speed and the volume.
- Calculates and converts the Intermittent interval automatically by using the AUTO VOLUME
when the ignition switch is in the "ON" position and the AUTO switch is in the "ON" position.
The wipers are operated in vehicle speed sensitive mode when turning the AUTO switch to the
- "ON" position with the engine running or starting the engine with the AUTO switch positioned to
"ON".

2. Vehicle speed calculation

[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.

1 [PULSE/SEC] =

3. VOLUME calculation
- The pause time of the vehicle speed sensitive AUTO wiper is calculated by the AUTO volume
(input voltage). Each level has the hysteresis.

4. Pause time calculation

- Pause time: the duration that wipers are stopped at parking position
- Elapsed time: the duration after the wiper motor started to operate from parking position
- The pause time is calculated by the vehicle speed and the VOLUME.
If the pause time is below 1.0 second, the wipers operate without pause.
If the pause time is over 1.5 seconds, the wipers operate intermittently.

1. Speed Sensitive INT Wiper

- The wiper relay stays ON for remaining period specified INT switch when turning off the
INT switch during INT operation.
- The wiper operates in previously set speed when turning ON the INT switch from OFF
position with the IGN ON.
- The wiper operates in previously set speed when turning ON the Ignition switch with the
switch ON.
2. Control during Faulty Wiper Motor Parking Function
- The wiper system continuously outputs (wiper Low relay ON) when the wiper parking
terminal is stuck in ground or IGN with INT switch ON or washer switch ON. The relays is
turned off immediately after turning off the INT switch.

1. OVERVIEW
The Immobilizer System provides an additional theft deterrent to the vehicle in which it is installed and
prevents it from being started by unauthorized persons. The transponder integrated in the key and the
engine control unit has the same code. When the ignition key with the integrated transponder is turned to
the ON position, the ECU (Engine Control Unit) checks the crypto code of the key and, if correct, allows
your vehicle to start the engine.

Diagnostic Connector REKES Key ECU

 What is the immobilizer system?(D20DT, D27DT, D27DTP, G32D)
The immobilizer system prevents the vehicle theft by allowing only the authorized key to start the engine.
The transponder inside the key communicates with the immobilizer installed in the key box, and the
system permits the engine to start after confirming the encrypted coding from the engine ECU. Refer to
the information that follows for specific functions and their descriptions.

3. OPERATING PROCESS (D20DTR)
1) Operation and Warning Lamp
(1) Operating process
1. The ECU sends the challenge message to immobilizer control unit when turning on the ignition. (It
requests the validation of key. If failed, sends validation signal 3 times in 2 seconds again. If the
validation is failed again, stop the validation and wait for 10 seconds, and then start new validation
process.)
2. The immobilizer control unit sends the crypto code to the transponder.
3. The transponder sends back the crypto signal to the immobilizer control unit as a response.

3) Outside Rearview Mirror Folding/Unfolding Function
(1) Folding/Unfolding
1. When pressing the folding switch for approx. 1 second, the outside rearview mirrors are
folded/unfolded.
2. This folding/unfolding function can be used for 24 to 30 seconds even after turning off the ignition
switch (However, this delayed operating time stops when opening the driver's door).
3. To prevent the motor from stopping during folding/unfolding process, this delayed operating time is
extended for additional 13 seconds if pressing the switch within 30 seconds (T2) after turning the
ignition OFF. If pressing the switch again during the additional operating time, the delayed operating
time is extended again for additional 13 seconds.

4) Easy Access Function

Seat Return Operation When Turning the Ignition Switch to ON Position
When turning the ignition switch to ON from OFF position with the easy access switch pressed, after 30
ms, STICS starts to send the return signal to SPWM unit. If SPWM receives the data properly, it
operates the return operation.

The prohibit conditions for the easy access seat return operation are as follows:
- The parking brake is released or the shift lever is in any position other than "P".
- Any of seat switch is operated during the return operation.
- Ignition switch is cycled (ON and OFF) with short interval (approx. 1 ~ 1.5 seconds) for over 3
seconds.
 Easy Access Operation When Getting Off
When removing the ignition key (key reminder switch OFF) from the ignition switch with the easy access
switch pressed, STICS sends the easy access data to SPWM unit.
The SPWM unit immediately moves the seat backwards for approx. 50 mm and lowers it as far as it
goes.

- If an error is detected from the motors (sliding motor/cushion front motor/cushion rear motor) during
operation after removing the ignition key, the motor with error stops its operation and other motors
continue to complete their operations.
-

9) ESP Warning Lamp

ESP Warning Lamp Blinking in Control

ESP warning lamp blinks when ESP control is activated. If the activation reaches a certain limitation, a
beep sounds to warn the driver. The ESP warning lamp goes off when ESP function is deactivated.Even
when the ESP is operated for a very short period of time, the ESP warning lamp blinks at least four
times every 175 milliseconds.
 ESP System Cancellation Using the ESP OFF Switch

When the ESP switch is pressed (for over

approximately 150ms), the ESP system will be
cancelled and the vehicle will be driven
regardless of the output values from the
corresponding sensors. Then, the ESP warning
lamp on the instrument panel comes on.

The detailed operation procedures are

as follows:

1. The ESP warning lamp comes on when the

ESP OFF switch is pressed for over 150ms.
The switch returns to normal position when
2. the OFF switch is released.
The ESP system will be cancelled after
3. approximately 150ms.

Based on the above procedures, we can see that the ESP system will be cancelled after a certain period
(approx. 150ms) from releasing the switch to the original position. The ESP system does not get
canceled immediately when the ESP warning lamp is turned on by pressingthe ESP OFF switch. When
you turn the ESP system off by pressing the ESP switch for over 150ms, the TCS system is turned off.
And the basic ABS system will operate.

In vehicle for EU market, the auto light function is not available.

- The LED stands for "Light Emitting Diode" or "Luminescent Diode." LED is a semiconductor
diode that emits incoherent narrow-spectrum light when electrically biased in the forward direction
of the p-n junction, as in the common LED circuit. In short, it is an element that converts electric
signals into light signals. Yellow, blue, red and white LEDs are currently available.
The followings are the advantages of LED.
- It is not glaring and doesn't have short circuit unlike the conventional lamps.
It is semi-permanent and doesn't generate heat.
Its power consumption is much lower than those of conventional bulbs.

Luminous Intensity
- Luminous intensity is a measure for the amount of light which passes through the unit area per
time unit. The SI unit of luminous intensity is the candela (cd), an SI base unit.

Luminance
- Luminance describes the amount of light that passes through or is emitted from a particular area,
and falls within a given solid angle. It is measured in stilb (sb) or nit (nt).

Intensity of illumination
- This indicates the amount of light reaching a given area. Measuring unit is lux (lx) and it is not
directly proportional to the brightness of the area as the reflection rate is not included.

2. CAUTIONS ON RAIN SENSOR

- When the wiper switch is in the AUTO position, the wiper will operate for 1 cycle if the initial engine
start is made. This may cause the wiper blades to wear prematurely. Therefore, other than rainy
days, set the switch to the OFF position. Especially during the winter time, check if the wiper
blades are not frozen to the windshield.
Operating the wiper with the blades frozen can damage the wiper motor.
- If you operate the wipers when the windshield is dry without spraying washer fluid, the windshield
can be scratched and the wiper blades can wear prematurely. Use the wiper with the washer fluid
when the windshield is dry.
- When it does not rain, turn the wiper switch to the OFF position.
- Turn the wiper switch to the OFF position before any car wash to avoid unwanted operation of the
wipers.

When cleaning the windshield over the sensor with damp clothes, the wiper may operate suddenly.
It could cause serious injury. Make sure to place the wiper switch to the OFF position and ignition
switch OFF when not in use.

Irregular operation (abrupt operation)

- Check if the sensor is off the position.
- Check if the rain sensor cover is securely installed.
- Check if the customer is familiar to how to control the wiper sensitivity.
Check if the wiper sensitivity control is set to the FAST side (step 5).
Check the wiper blade for wear.
- If the wiper blade cannot wipe the glass uniformly and clearly, it may cause the rain sensor to
- work irregularly. Therefore, in this case, replace the wiper blade with a new one.

1) Power-up Reminder Wiper
1. When turning off and on the INT auto switch, the system drives the wiper motor for one cycle through
LOW relay regardless of communication with rain sensor.
2. When the INT/AUTO wiper switch is turned on from off with the ignition switch ON, the wiper low relay
is turned on once to operate the wiper motor regardless of the rain sensor signals. After then, the wiper
does not operate even when the INT/AUTO wiper switch is turned on from off. The wiper operates at
low speed only when the rain sensor detects the rain drops.
2) Washer Coupled Wiper Operation During Rain Sensor Coupled
Operation
1. When the washer switch is turned on during rain sensor coupled operation with IGN ON and
INT/AUTO switch ON, the communication with rain sensor is overridden and the wiper system
operates in washer coupled wiper operation mode. However, if the signal from rain sensor is the
continuous operation, the washer relay is turned on and the wiper keeps on running when the washer
switch is ON.
2. Even though the wiper system is in washer coupled wiper operation mode, the operating data should
be sent to rain sensor.
 8611-09

3) Sensitivity Control (Instant Wiping)

1.
switch ON and wiper motor STOP (parking position), the wiper motor operates one cycle at low
speed. (Only when the rain sensor detects rain drops)
* If the wiping speed control switch is changed more than 1 stages within 2 seconds, the wiper motor
operates only one cycle.

4) Auto Light Control

1. Only when the auto light switch is in "AUTO" position, it controls the tail lamp and headlamp by
communicating with the rain sensor (while the ignition key is in "ON" position).
5) For Abnormal Wiper Parking Signal
1. The wiper system continuously sends the signal for current status when the wiper parking terminal is
stuck in ground with IGN2 ON and intermittent wiper switch in "AUTO" position.
* The wiper motor is operated only when there is a request from the rain sensor.
 8611-09

6) For faulty rain sensor

1. When the wiper speed control switch is turned to step 2 from step 3, the wiper motor operates
one cycle at low speed if STICS receives a faulty sensor signal (S_RSFAULT) from rain sensor
unit with IGN ON and INT/AUTO switch ON.

2. When the wiper speed control switch is turned to step 3 from step 4, the wiper motor operates one
cycle at low speed if STICS receives a faulty sensor signal (S_COMMFAULT) from rain sensor unit
with IGN ON and INT/AUTO switch ON.
3. OPERATION MODE OF RAIN SENSING WIPER SYSTEM

1. Rain detected headlamp:

If it rains heavy which requires the intermediate INT speed, the headlamps are turned on
automatically.
2. Night detected wiping:
When the auto light control turns on the headlamps and the rain sensor detects the rain, the wiper
sensitivity is automatically increased by one level.
(For example, the AUTO wiper switch is at the 3rd level, but the wiper operates at the 4th level.)

2. FEATURES
1) Features
Early Downshifts with Hard Braking and Skip Shifts

When heavy braking is detected, the transmission downshifts early and skips gears to provide
increased engine braking to provide gear selection for tip-in.

Gear Hold on Uphill/Downhill

If the accelerator pedal is released when travelling uphill, upshifts are prevented to reduce
busyness on grades. If the accelerator pedal is released when travelling downhill, upshifts are
prevented to enhance engine braking.

A soft engagement feature avoids harsh take up of drive when selecting Drive or Reverse. This is
achieved by limiting engine speed and engine torque which results in a rapid, but progressive
engagement of either Drive or Reverse when moving from the Park or Neutral positions. There is
no drive engagement prevention strategy implemented on the transmission system as there is
sufficient engine strategy to protect the system. However, reverse gear engagement is prevented
until engine speed is less than 1400 rpm and the accelerator pedal position is less than 12% and
vehicle speed is less than 10 km/h.

Converter Clutch Lock-Up In All Gears

The transmission features converter clutch lock-up in all gears. This feature provides improved
fuel economy and vehicle performance. It also improves transmission cooling efficiency when
towing heavy loads at low speeds, e.g. in city driving or hill terrain.

Embeded Memory Module (EMM)

The embedded memory module (EMM) is matched to the transmission's valve bodies during
transmission assembly to ensure refined shift quality. The EMM is integrated into the input speed
sensor which is mounted on the valve body in the transmission. The EMM is used to store data
such as valve body calibration data and valve body serial number. Upon installation, the TCU will
download the data from the EMM and utilise this data in the operation of the transmission.
 3650-01

2) Cooling System
The transmission cooling system ensures rapid warm-up and constant operating temperature
resulting in reduced fuel consumption and refined shift quality.
It also includes a cooler by-pass within the hydraulic system to allow sufficient cooling and
lubrication to the transmission drivetrain in the event of a blockage in the transmission cooler.

3) Shift Strategy
Gear Shift

Transmission gear change is controlled by the TCU. The TCU receives inputs from various engine
and vehicle sensors to select shift schedules and to control the shift feel and torque converter
clutch (TCC) operation at each gear change.

Coastdown

Coastdown downshifts occur at 0% accelerator pedal when the vehicle is coasting down to a
stop. To reduce the shift shock and to improve the shift feeling during downshift, TCU
electronically controls the transmission.

Torque Demand

Torque demand downshifts occur (automatically) when the driver demand for torque is greater
than the engine can provide at that gear ratio. If applied, the transmission will disengage the TCC
to provide added acceleration.

This allows the driver to define the highest possible gear by selecting "+" or "-" on the gear
selector when the lever is in the "M" position. When the lever is first moved to the manual "M"
position the transmission will select the lowest possible gear.
When maximum engine rpm is reached the transmission will upshift automatically regardless of
the driver selected limit. 4WD models with low range will not automatically upshift when low range
is selected.

Kickdown Function
If you need to accelerate rapidly, depress the accelerator pedal completely to the floor.
Then, a one- or two-lever gear will automatically be engaged. This is called the Kickdown
function.

1st gear position

- Use on a rugged road, mountain path and steep hill. Engine braking effect on steep hill is
available.

2nd gear position

- Use on a long and gentle slope. 2-1 automatic kickdown shift is available. Engine braking

3st gear position

- Use on a long and gentle slope. 3-2 and 2-1 automatic kickdown shift is available. Engine
braking effect is available.

4th gear position

- Use on a long and gentle slope. 4-3, 4-2 and 4-1 automatic kickdown shift is available.

5th gear position

- 5-4 and 5-3 automatic kickdown shift is available.

6th gear position

- 6-5 and 6-4 automatic kickdown shift is available.

4. LIMP HOME MODE
In case of transmission malfunction
1. If a serious fault occurs in the automatic transmission, the TCU enters the limp home mode to
secure safe driving and protect the automatic transmission.
2. As power is no longer supplied to the solenoid, the current basic function (P, R, N, D) is
maintained and the 4th gear can be maintained only by the operation of the hydraulic system
without electrical operation.
3. The ECU communicates with other electric modules with CAN. If a serious fault occurs, the
transmission automatically enters the limp home mode for service.
4. The TCU monitors all factors which can affect to the performance of the transmission and
diagnose the system according to OBD II regulation.

In case of overheated transmission

1. The TCU enters the limp home mode when the batter voltage drops below 8 V.
2. If the transmission is overheated, the shift pattern is changed to the hot mode to cool the
transmission more efficiently.
3. While the transmission is overheated, the selector lever symbol and engine temperature
warning lamp on the instrument cluster blink until the transmission is cooled down to the
normal operation temperature. If the transmission is excessively overheated, the gear cannot
be shifted but remains in the neutral position.

Towing the vehicle with A/T

The best way to transport the vehicle is to load it to a truck and transport it, especially if the
vehicle is 4WD.
- If towing the vehicle with the propeller shaft connected, the transmission or oil pump of
transfer case may malfunction, resulting in internal damage due to poor lubrication.
 3650-01

5. ELECTRONIC CONTROL SYSTEM

1) Overview
The transmission control unit (TCU) and its input/output networks control the operations of
transmission:

- Shift timing
- Line pressure
- Clutch pressure (shift feel)
- Torque converter clutch

In addition, the TCU receives input signals from certain transmission-related sensors and
switches. The TCU also uses these signals when determining transmission operating strategy.
Using all of these input signals, the TCU can determine when the time and conditions are right for
a shift, or when to apply or release the torque converter clutch. It will also determine the pressure
needed to optimise shift feel. To accomplish this, the TCU operates six variable bleed control
solenoids and four ON/OFF solenoids to control the operations of transmission.

2) Transmission Control Unit (TCU)

TCU use the power from the ignition power supply to start and stop its operation. TCU is
connected to the transmission with 26-pin connector. TCU processes the signals and information
(analog and digital) through CAN bus from the sensors.

- Transmission input speed - Transmission oil temperature

- Transmission output speed - Brake pedal status
- Accelerator pedal position - Engine oil temperature
- Gear selector position - Engine coolant temperature
- Engine torque - Ambient air temperature
- Engine speed - Barometric pressure

This information is used by the TCU to decide which shift pattern to select and for shift energy
management. Electro-hydraulic solenoid valves and variable bleed solenoids control the
transmission gear changes.
Six variable bleed solenoids and four on/off solenoids are used to direct transmission fluid flow to
control the fluid pressure within the three clutches and two bands. Separate pressure regulators
are used exclusively for torque converter clutch control and main transmission line pressure.
The TCU monitors all TCU inputs and outputs to confirm correct system operation. If a fault
occurs the TCU is able to perform default action and inform the driver of the problem through the
instrument cluster warning lights. Detailed information is available via trouble codes which can be
read with the service tool.
3) Transmission Control Monitoring System
TCU monitors all input and output signals to identify possible failures. If a fault is detected, TCU

Monitoring the Supply Voltage

If the battery voltage is too high or too low, the TCU sets the DTC.

Monitoring the Supply Voltage to Solenoid

TCU monitors the circuits for open or short to ground or supply. The monitoring function
evaluates the voltage characteristics while the switch is ON.

Monitoring the Gear Ratio

TCU monitors the gear is engaged properly in the allowed time.

Monitoring the Torque Converter

TCU checks if the torque converter can be locked up properly. If it is failed, TCU releases the
torque converter clutch to activate the fail-safe operation.

4) Shift Energy Management

This function involves reducing or increasing the engine output torque during shifting. This
reduces the energy which is dissipated in the friction elements of the transmission during up-
shift. This is done by reducing the engine torque during the gear ratio change without interrupting
the tractive drive.
This function is used for:

- Increasing the life span of transmission by shortening the slipping time

- Improving the shift comfort by reducing the step changes due to gearshift
- Transferring a higher engine power

Real-time control of engine torque is required to maintain the proper shift operations and the
durability of transmission. TCU controls the engine torque during the gearshift by synchronizing
the operation of transmission clutches.
 3650-01

Pressure Modulation

To provide a higher level of shift comfort and durability, the hydraulic pressure in the shift related
friction elements of the transmission must be matched accurately to the input torque to
transmission. This hydraulic pressure is composed of a hydraulically pre-set basic pressure and a
control pressure which is set by one of the variable bleed solenoids.

The transmission input torque can be directly calculated from the following operating parameters:

- engine torque signals

- engine speed or any signal transmitted from ECU through CAN lines
- converter slip

Separate pressure characteristics for each gear change make it possible to adapt precisely to the
particular shift operation.

5) Shift Mode Selection by TCU

The driver can select Standard (S) or Winter mode (W) with the mode switch. TCU automatically
changes the shift mode according to the transmission oil temperature, uphill or downhill gradient,
and altitude to keep the good driving conditions.

Standard Mode (S)

Standard Mode is selected when setting the mode switch in Standard (S) position with the gear

timing provides the optimized fuel economy and good driving conditions.

Uphii and Downhill Mode

In this mode, the operating points of torque converter lock-up clutch and the shifting points are
adjusted according to the vehicle weight.

Altitude Mode

In this mode, the shifting points are automatically adjusted according to the altitude to compensate
the engine torque changes due to barometric pressure and temperature.
 Winter Mode (W)

When the Winter mode is selected, the second gear is engaged to start off the vehicle easily to
prevent wheel spin on slippery surfaces and WINTER mode indicator comes ON. The first gear is
not available in this mode.

Low Range Driving Mode

When the vehicle is in 4L driving mode, the transmission uses a different shift mode to optimize
the low range driving. Similar to Winter mode, the first gear is not available.

Warm Up Mode

transmission.

Hot Mode

and reduces the load to the transmission. This is called Hot Mode.

- PWM fan ON
- the engine torque is reduced and WINTER indicator is blinking
- the transmission is held in Neutral (N) gear until the oil temperature falls

In Hot Mode, any of shift mode is not available.

Auto Cruise Control

When the auto cruise control is activated, the engine ECU requests the downshift to increase the
engine brake effect.
 3650-01

6. CAN NETWORK
1) Network Communication

The TCU sends signals to be used by other vehicle systems via the CAN bus, such as:
- Selector lever position
- Selected gear state
- Manual mode activation
- Output torque
- Transmission fluid temperature
- Engine torque reduction requests

2) Embeded Memory Module (EMM)

The embedded memory module (EMM) is
matched to the transmission's valve bodies
during transmission assembly to ensure
refined shift quality. The EMM is integrated into
the input speed sensor which is mounted on
the valve body in the transmission. The EMM
is used to store data such as valve body
calibration data and valve body serial number.
Upon installation, the TCU will download the
data from the EMM and utilise this data in the
operation of the transmission.

DCAG 5-speed automatic transmission is an electronically controlled 5-speed transmission with

a lockup clutch in the torque converter. The ratios for the gears are realized by three planetary
gear sets. The 5th gear is designed with a step-up ratio of 0.83 as an overdrive. The selector
lever is controlled by electronically and mechanically. The gears are shifted by the corresponding
combination of three hydraulically actuated multiple-disc brakes, three hydraulically actuated
multiple-disc clutches and two mechanical one-way clutches. This electronically controlled
automatic transmission adjusts the operating pressure to provide proper shifting in relation to
engine power. This function improves shifting quality significantly. And, the driver can select "S"
(Standard) mode or "W" (Winter) mode according to the driving conditions. This automatic
transmission provides two gears even during reverse driving. The internal sensors and controls
are connected to TCU by cylindrical 13-pin connector.

DCAG 5-speed automatic transmission offers The old version of torque converter is not
the following advantages: compatible with new torque converter for
1. Improved shifting quality MB 5-speed transmission.
2. More gears
3. Extended working life and reliability Torque converter P/N
4. Reduced fuel consumption with Damper A 211 250 19 02

gallery).
 3170-01

Synchronizer element
A cone or sleeve that slides to and fro on the transmission main shaft and makes the gears rotate
at the same speed to prevent clash when the gears are about to mesh. Whenever a vehicle is
rolling, the transmission main shaft is turning and the clutch gear is spinning. Even though the
clutch is disengaged, the clutch gear continues to spin until friction slows it down or stops it.
Thus when the driver shifts into another gear he is trying to mesh gears that may be moving at
different speeds. By using synchronizers, the possibility of broken or damaged teeth is reduced
and shifting effort is lowered.

1. OVERVIEW
The AWD transfer case is installed to the full time 4WD vehicle. Unlike the TOD (Torque On
Demand) transfer case, it delivers the driving force to the front wheels through the internal
planetary gears without a control unit to operate AWD function. It also doesn't have the TC
(Transfer Case) shift motor and 4WD transfer switch. Since it doesn't have a control unit such as
TCCU (Transfer Case Control Unit), it delivers the driving force to the front and rear propeller
shafts according to the gear ratio based on the gear combinations. The distribution ratio of driving
force is 40:60 (front wheels:rear wheels).

5. OPERATION OF DIFFERENTIAL
1) Systematic Diagram

2) Revolution Control
When there is a revolution difference due to the gap of turning radius while cornering, the tight
corner braking symptom occurs in part time transfer case. However, for the AWD, this gap of
turning radius is compensated by the differential so that the tight corner braking symptom will not
occur. The ESP also operates the wheel slip under control in order to keep the vehicle stable
under severe conditions such as icy road.
 When Revolution Difference Does not Occur

If there is no revolution difference in front and rear shafts, the step pinion (19T/13T) and the
pinion (16T) are fixed (integrated to the carrier) even when the carrier rotates. It makes the front
sun gear and the rear sun gear move toward the moving direction with the torque ratio of 40:60.

When Revolution Difference Occurs

The front wheels should rotate faster than the rear wheels while cornering (including wheel slip)
since the front wheels' turning radius is larger than the rear wheels'. At this moment, the step
pinion (19T/13T) should rotate faster than the pinion (13T) in relation to the carrier's movement.
This function is similar to the regular differential function, which also compensates the revolution
difference while maintaining the torque ratio in 40:60 (front:rear).
 3240-01

1. SPECIFICATIONS
1. OVERVIEW

TOD system means the full time 4WD system and the registered trade mark of Borg Warner.
TOD is an abbreviation of Torque On Demand.
TOD (Torque On Demand) system, which is superior than existing Full Time 4WD, checks the
road surface and vehicle conditions via various sensors and, subsequently, according to the
situations and conditions, distributes the most optimal driving force to front wheels and rear
wheels by activating the electro-magnetic clutch located inside of TOD Transfer Case.

TOD receives the speed signals from speed sensors installed in front axle and rear axle, the TPS
signals from engine, and the operating signals from ABS control unit via CAN. Based on these
data, TOD control unit controls the electro-magnetic clutch to distribute the 3:97 ~ 44:56 of
driving force to front wheels and rear wheels.
The conventional system uses "FR driving" (theoretically, the 100% of driving force is transferred
to rear wheels) on normal paved road. When the system detects a slip in the rear wheels, a
proper percentage of driving force is transferred to front wheels.

TOD control unit receives the wheel speed signals from the speed sensors in propeller shaft of
transfer case and engine output information from the engine control unit. TOD control unit
changes the pressure force of the electromagnetic clutch based on the analyzed data.
 3240-01

1) Distribution of Driving Force According to Road Surface

1. On normal road surface In vehicle with existing part time transfer case, when a driver turns the
steering wheel to park in the 4WD mode, the vehicle may halt sensation of tight corner braking
phenomena. However, in vehicle with TOD system, this phenomena does not occur and the
driving force is properly and automatically distributed.
2. On paved road with high speed Driving at high speed on roads such as highway mainly uses
rear wheels as driving wheel. At this moment, some of torques is also distributed to front
wheels so that the vehicle could maintain safe ground grab capacity against side winds and
rain. Distribution ratio: 15% for front wheels and 85% for rear wheels.

3. When turning on the road with low friction rate During cornering on roads such as unpaved,
snowy, icy and muddy, ground grab capacity is increased by distributing required torque and,
at the same time, comfortable steering operation is maintained by controlling the ground grab
capacity at high level.
Distribution ratio: 30 % for front wheels and 70 % for rear wheels.

4. When climbing or starting off on the road with low friction rate In order to secure the maximum
ground grab capacity and driving force during climbing or starting off on the roads such as
unpaved, snowy and icy road, the system controls the driving force to distribute properly in full
4WD mode. Distribution ratio: 50 % for front wheels and 50 % for rear wheels.
2) Function
Selection Mode 4L Mode
When selecting 4L mode, EMC is locked to
apply maximum torque into front and rear
propeller shafts. Shift motor rotates also 4L
position by rotation of cam thus propeller
shaft torque changes from 1:1 to 2.48:1 by
planetary gear set.

Releasing the 4L Mode

When selecting 4H mode, 4L drive mode is
released and 4H mode is resumed.
"4H" switch: Self-return type
The TOD system has 2 selectable mode, 4H "4L" switch: Push lock type
and 4L. 4H is the normal operating mode
when drive of which gear ratio is 1:1 and 4L
mode distributes power to front and rear
wheels 50 : 50 of which gear ratio is 2.48:1.

3) 4WD Operation Overview

- To make the mode shift easier, stop the vehicle, depress the brake pedal, select the mode
switch, and move the selector lever with the sequence of [N-P-N].

1) Distribution of Driving Force According to Road Surface
1. On normal road surface
In vehicle with existing part time transfer case, when a driver turns the steering wheel to park in
the 4WD mode, the vehicle may halt sensation of tight corner braking phenomena. However, in
vehicle with TOD system, this phenomenon does not occur and the driving force is properly
and automatically distributed.

2. On paved road with high speed

Driving at high speed on roads such as highway mainly uses rear wheels as driving wheel. At
this moment, some of torques is also distributed to front wheels so that the vehicle could
maintain safe ground grab capacity against side winds and rain. Distribution ratio: 15% for front
wheels and 85% for rear wheels.

3. When turning on the road with low friction rate

During cornering on roads such as unpaved, snowy, icy and muddy, ground grab capacity is
increased by distributing required torque and, at the same time, comfortable steering operation
is maintained by controlling the ground grab capacity at high level.
Distribution ratio: 30 % for front wheels and 70 % for rear wheels.

4. When climbing or starting off on the road with low friction rate
In order to secure the maximum ground grab capacity and driving force during climbing or
starting off on the roads such as unpaved, snowy and icy road, the system controls the driving
force to distribute properly in full 4WD mode. Distribution ratio: 50 % for front wheels and 50 %
for rear wheels.

2) Mode Selection
The TOD system has 2 selectable mode, 4H
and 4L. 4H is the normal operating mode
when drive of which gear ratio is 1:1 and 4L
mode distributes power to front and rear
wheels 50:50 of which gear ratio is 2.48:1.
 0000-00

4L Mode

When selecting 4L mode, EMC is locked to apply maximum torque into front and rear propeller
shafts. Shift motor rotates also 4L position by rotation of cam thus propeller shaft torque changes
from 1:1 to 2.48:1 by planetary gear set.

Releasing the 4L Mode

When selecting 4H mode, 4L drive mode is released and 4H mode is resumed.

- "4H" switch: Self-return type
- "4L" switch: Push lock type

3) 4WD Operation Overview

To make the mode shift easier, stop the vehicle, depress the brake pedal, select the mode
switch, and move the selector lever with the sequence of [N-P-N].

1. OVERVIEW
Suspension is the term given to the system of springs, shock absorbers and linkages that
connects a vehicle to its wheels. Suspension systems serve a dual purpose ? contributing to the
vehicle's road holding/handling and braking for good active safety and driving pleasure, and
keeping vehicle occupants comfortable and reasonably well isolated from road noise, bumps,
and vibrations, etc. These goals are generally at odds, so the tuning of suspensions involves
finding the right compromise. It is important for the suspension to keep the road wheel in contact
with the road surface as much as possible, because all the forces acting on the vehicle do so
through the contact patches of the tires. The design of front and rear suspension of a vehicle
may be different.
Under View (4WD, Automatic Transmission)

Front suspension

Rear suspension
2. FRONT SUSPENSION (DOUBLE WISHBONE)
Double wishbone suspension is an independent suspension design using two (occasionally
parallel) wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting
points to the chassis and one joint at the knuckle. The shock absorber and coil spring mount to
the wishbones to control vertical movement. Double wishbone designs allow the engineer to
carefully control the motion of the wheel throughout suspension travel, controlling such
parameters as camber angle, caster angle, toe pattern, roll center height, scrub radius, scuff and
more.

Lower arm Upper arm Shock absorber Stabilizer

Advantage
1. The advantage of a double wishbone suspension is that it is fairly easy to work out the effect
of moving each joint, so the kinematics of the suspension can be tuned easily and wheel
motion can be optimized.
2. It is also easy to work out the loads that different parts will be subjected to which allows more
optimized lightweight parts to be designed.
3. They also provide increasing negative camber gain all the way to full jounce travel unlike the
MacPherson strut which provides negative camber gain only at the beginning of jounce travel
and then reverses into positive camber gain at high jounce amounts.
Disadvantage
1. The disadvantage is that it is slightly more complex than other systems like a MacPherson strut.
2. Due to the increased number of components within the suspension setup it takes much longer to
service and is heavier than an equivalent MacPherson design.
 4411-01

3. REAR SUSPENSION (MULTI LINK TYPE)

Multi-link (5-Link) type suspension is the independent suspension. It provides good ride comfort
and drivability by reducing the coil spring weight. Also, it increases the space for passenger
compartment by lowering the floor. This type of suspension consists of multiple links such as coil
spring, shock absorber, upper and lower arms, lateral rod and stabilizer bar.

4. WHEEL ALIGNMENT
Wheel alignment (adjustment of Camber, Caster and Toe) is part of standard automobile
maintenance that consists of adjusting the angles of the wheels so that they are set to the
specification. The purpose of these adjustments is to reduce tire wear, and to ensure that vehicle
travel is straight and true (without "pulling" to one side). Alignment angles can also be altered
beyond the specifications to obtain a specific handling characteristic.

Necessity for Wheel Alignment

Wheel alignment consists of adjusting the angles of the wheels so that they are perpendicular to
the ground and parallel to each other. The purpose of these adjustments is maximum tire life and
a vehicle that tracks straight and true when driving along a straight and level road.
The symptoms of a vehicle that is out of alignment are:
Uneven or rapid tire wear
Pulling or drifting away from a straight line
Wandering on a straight level road
Spokes of the steering wheel off to one side while driving on a straight and level road.
 4411-01

1) Toe-in
The difference of measured distances between the front ends of the tires (A) and the rear ends of
the tires (B) along the same axle when viewed the wheels from the top.

Toe-in

When viewed from the top, the distance between the tire centers is smaller in the front than in
the rear.
- Side slip protection
- Parallel front wheels rotation (straight ahead driving is ensured by toe-in to prevent the
wheels from tilting outwards by the camber while driving)
- Prevention of uneven (outward) tire wear
Prevention of toe-out from wearing of steering linkage
2) Camber
The angle between the center line of the tire and the vertical line when viewed from the front of
the vehicle

LH
Camber
RH

Positive camber: Top of the tire is tilted outward

Advantages: - The axle is not bent when it is loaded.
- The force required to operate the steering wheel is reduced due to smaller
contact area (or load area) of the tire.
- Restoring force of the steering wheel is gained (when turning the steering
wheel, the tire circles and the force to lift the frame is applied. In this case,
the shock absorber contracts and the restoration force is applied to the
steering wheel.)
Disadvantages: - Cornering force decreases as the positive camber increases when the
vehicle makes turn.
- The hub bearing is worn unevenly if camber is excessive.

Zero camber: When the tire center line is perpendicular to the ground level

Negative camber
Advantages: - Better traction force due to wide load area (applicable for off-road vehicle)
- Better corner driving when the vehicle makes turn as the cornering force
Disadvantages: - The axle is easy to be bent or deviated in the negative camber than in the
positive camber when load is applied on the axle.
- Difficult to control due to wide load area.
 4411-01

3) Caster
The angle between the vertical line and king pin, which fixes the steering knuckle and front axle,
(steering column which connects the top and bottom ball joints in the independent axle type)
when viewed the tires from the side.

LH
Caster
RH

Caster: With considering the height difference between the wheel centers of the front and
rear wheels. (Under standard condition that the vehicle is on a level ground)

Positive caster: Top of the king pin is tilted backward from the vertical line of the wheel
center when viewed the tires from the side
Advantages: - Directional force to go straight (following control)
- Restoring force of the wheel (restored to the straight ahead direction)
- Prevention of wheel shimmy (wheels wobble left and right)

Negative caster: Top of the king pin is tilted forward from the vertical line of the wheel center
when viewed the tires from the side
Advantages: - Smaller turning radius
Disadvantages: - Impact from the road is transferred to the steering wheel (steering wheel
turns)
- Poor straightness

Brake operation and noise

This section describes the noise phenomena occurred possibly in the brake system operation.
Distinguish between the information given below and the actual problems and then, inspect the
vehicle and take appropriate measures.

- Noise symptoms and Causes

Symptom 1. If depressing the brake pedal when the engine is cold, "screeching" sound always
occurs and, after driving for a while, the sound disappears..

This usually occurs in the morning. When the temperature goes down, the dew condensation
phenomenon sets moisture on the brake disc as the window frost forms. Due to this moisture, the
iron within the brake disc and pad oxidizes, forming undetectable micro-rusts on the disc
surface. When starting the engine under this condition, noise may sound due to the friction of
micro-rusts. When operating the brake several times, the disc temperature goes up and the
micro-rusts come off and the noise goes away. Depending on the driving conditions, noise gets
louder when slightly depressing the brake pedal and oppositely, noise is smaller when deeply
depressing the brake pedal. This is simply a physical phenomenon, called "morning effect" in
professional terms, and does not imply any problems with the brake system.

Symptom 2. Slip or screech after the brake pad replacement.

This usually occurs when the bed-in is not made between the disc and the pad's friction material.
The bed-in is a state that the brake system normally works and gives no noise out, when, after
about 300 km city driving, the contact area of the pad friction material is enlarged and the disk is
in complete contact with the pad's friction material. Therefore, for some time after the brake
disk/pad replacement, the brake system poorly operates or noise (abnormal sound) occurs due
to the partial contact.

Symptom 3. "Groaning" sound occurs in the automatic transmission vehicle when slightly
taking the foot off the brake pedal to slowly start after waiting for the signal, or slightly
depressing the brake pedal.

This is the noise "Creep groan" that occurs when, in both the automatic and manual transmission,
slightly releasing the brake pedal in the neutral gear at downhill roads.
It frequently occurs at the low braking power and low speed, through the following process. When
operating the brake system at low speed and low pressure, adhesion and slip repeatedly take
place between the brake disk and the friction material, and this makes the braking power
inconstant, instantly increasing or decreasing, and gives out the brake noise.
It is also a physical phenomenon and has no relation with the brake performance.
3. AIR BLEEDING

- Never reuse the used brake fluid.

- Use only specifies brake fluid (DOT 4). Add brake fluid between MAX and MIN lines on the
reservoir (0.7 to 0.8 liters).
- Be careful not to splash the brake fluid on painted area or body.
- Make sure that any foreign material does not get into brake line.
- Always work with another staff.

A. Fill up the brake fluid up to "MAX" line on

the reservoir.

B. Fill the reservoir with brake fluid and

pump the brake pedal several times.
Then keep it depressed.

C. Loosen the bleed screw and collect the

I. adjust the stop lamp switch assembly
again.
J. If the stop lamps come on, tighten the
lock nut and measure the pedal height
again.

If the measurement is out of the specified

value, loosen the lock nut and adjust the
pedal height.
 - Check the pedal free play with below
procedures:
A. Stop the engine.
B. Depress the brake pedal several times to
discharge the vacuum pressure of the
brake booster.
C. Depress the brake pedal until you feel
the resistance, and measure the
movement (A).

Specified value (A) 3 ~ 8 mm

If the free play is below the specified value,

check if the clearance between the outer
case of the stop lamp and the brake pedal is
within the specified range. If the clearance is
out of the specified range, the clearance
between the clevis pin and the brake pedal
arm is too large. Check the components and
repair if needed.

A. Connect the multimeter to stop lamp

switch connector (N.O.) and check if the
continuity exists when pushing in the
plunger. If the continuity doesn't exist, the

A. Let the engine run for 1 to 2 minutes and

stop it. If the brake pedal stroke is
shortened as pumping the brake pedal,
the system is normal. If not, the system is
defective.

B. Depress the brake pedal several times with

engine off. If the brake goes down when
starting engine with pedal depressed, the
system is normal. If not, the system is
defective.

C. Depress the brake pedal when the engine

is running. If the pedal height is not
changed for 30 seconds after stopping the
engine, the system is normal. If not, the
system is defective.

If the above three checks are OK, the system

is normal. If any condition is not met, check
the valve, vacuum hose and brake booster.

The water in the brake fluid has an adverse effect to the brake system. If the fluid contains
around 3% of water, the boiling point of the brake fluid goes down by 25%. It will cause the
vapor lock frequently.
Water content in fluid: around 3% after 18 months, around 7~10% after few years
The water ib fluid makes the corrosion in the brake lines, deforms and deteriorates the rubber
components, brake calipers and pistons.

1. OVERVIEW
Even though a driver cuts off the power, while driving, the vehicle continues to move due to the
law of inertia. Therefore, a braking device is needed to stop the vehicle. The brake system
normally uses the frictional discs that converts the kinetic energy to the thermal energy by
frictional operation. The brake system consists of the brake disc (front wheel), brake disc or drum
(rear wheel), parking brake (mechanical type), master cylinder, booster, pedal and supply lines
(pipes and hoses).

This system uses the leverage effect and

Pascal's principle. When depressing the
brake pedal, the pedal pressure is increased
by booster and is delivered to master cylinder
to generate hydraulic pressure. The hydraulic
pressure generated by the master cylinder is
delivered to the brake caliper through the
brake pipes or hoses. This hydraulic pressure
pushes the brake calipers, accordingly the
caliper pads are contacted to brake disc to
generate the braking force.

Brake pedal uses the leverage effect to apply

bigger force to the brake master cylinder.
Stopping distance = free running distance + braking distance

What is stopping distance?

A certain distance (free running distance + braking distance) is needed from the moment an
obstacle appears ahead until you bring your vehicle to a complete stop. This is called as stopping
distance.

What is braking distance?

Tire slip occurs until the vehicle stops completely when the the brake is applied.
This slip is what we call a braking distance.

What is free running distance?

The free running distance is the time from the driver sees the obstacles and begins to prepare for
depressing the brake pedal until the moment the brake pedal is depressed.

When braking suddenly or braking on slippery roads, the vehicle keeps moving forward but the
wheels are locking and not rotating. If these happen, the vehicle may lose stability or rotate
resulting in an accident. ABS helps to maintain directional stability and control of the vehicle. ABS
is designed to secure more safety and increase the control of steering wheel during emergency
braking situation. But, ABS does not guarantee perfect safety beyond its physical limit. ABS in this
vehicle contains EBD function. In normal driving conditions, the brake system operates without
ABS function.

3. ABS CONTROL LOGIC

The principal ABS control logic is the determination of the reference speed by choosing one
wheel meeting a certain condition, while sensing the speed information from 4 wheel speed
sensors when the vehicle is being driven.
For example, when the comparison of the reference speed with front right wheel speed shows a
slip, the control signal is determined according to whether it's deceleration or acceleration. If the
control conditions are met, the brake for the front right wheel will be got under control.

1) Block Diagram of ABS HECU
 4892-01

2) Basic Theory of ABS Function

To give you a better understanding of the tasks and functions of ABS, we will first look at the
physics principles.

(1) Stopping distance

The stopping distance depends on the vehicle weight and initial speed when braking starts. This
also applies for vehicle with ABS, where ABS always tries to set an optimum brake force on each
wheel. As great forces are exerted between the tires and the carriageway when braking, even with
ABS the wheels may scream and rubber is left on the road. With an ABS skid mark one may be
able to clearly recognize the tire profile. The skid mark of an ABS vehicle does not however leave
any hint of the speed of the vehicle in the case of an accident, as it can only be clearly drawn at
the start of braking.

(2) Brake force on a wheel

The maximum possible brake force on a wheel depends on the wheel load and the adhesion
coefficient between tire and carriageway. With a low adhesion coefficient the brake force, which
can be obtained is very low. You are bound to know the result already from driving on winter
roads. With a high adhesion coefficient on a dry road, the brake force, which can be obtained, is
considerably higher. The brake force, which can be obtained, can be calculated from below
formula:

Maximum brake force

FBmax =
wheel load FR x coefficient of frictionMh

The braking process cannot be described

sufficiently accurately with the brake forces
calculated. The values calculated only apply if
the wheel is not locked. In the case of a
locking wheel, the static friction turns into
lower sliding friction, with the result that the
stopping distance is increased. This loss of
friction is termed "slip" in specialist literature.
 Slip
The brake slip is the difference between the vehicle speed and the wheel circumference speed. If
the wheel locks, the slip is greatest, that is 100 %. If the wheel is running freely and un-braked,
the slip is the lowest, equal to 0 %. Slip can be calculated from the vehicle speed Vveh and the
wheel speed Vw. The equation for this is:

Vveh = 100 km/h, Vw = 70 km/h

Vveh - Vw
Slip ratio (S) = X 100%
Vveh

S = 30%

Typical Slip Curves

For the various road conditions, the friction

coefficients were plotted. The typical course
of the curves is always the same. The only
special feature is shown by the curve for
freshly fallen snow, for this curve increases at
100 % slip. In a vehicle without ABS, the
wheel locks on braking and therefore pushes
a wedge before it. This wedge of loose
surface or freshly fallen snow means and
increased resistance and as a result the
stopping distance is shorter. This reduction in
stopping distance is not possible with a
vehicle with ABS, as the wheel does not lock.
On these surfaces the stopping distance with
ABS is longer than without ABS. The reason
for this is based in physics and not in the
Anti-Lock System.
However, as mentioned before, ABS is not
about the stopping distance, but
maneuverability and driving stability, for the
vehicle with locking wheels without ABS
cannot be steered.
 4892-01

KAMM circle
Before we go into the Kamm circle, you should
know that a tire offers a maximum of 100 %
transmissibility. It is all the same for the tire
whether we require 100 % in the direction of
braking or in the direction of the acting lateral
force, e.g. when driving round curves. If we
drive into a curve too fast and the tire requires
100 % transmissibility as cornering force, the
tire cannot transmit any additional brake force.
In spite of the ABS the car is carried out of the
curve. The relationship between brake force B
and cornering force S is shown very clearly in
the Kamm circle. If we put a vehicle wheel in
this circle, the relationship becomes even
clearer. In this relationship: as long as the
acting forces and the resulting force remain
within the circle, the vehicle is stable to drive. If
a force exceeds the circle, the vehicle leaves
the road.

Brake and cornering force

- Brake force
When depressing the brake pedal the brake
force increases to the maximum, then the
brake force decreases until the wheel locks.
Cornering force
- The cornering force is a maximum when the
wheel is turning freely with zero slip. When
braking the cornering force falls to zero if the
wheel locks (slip 100 %).
ABS operating range
The operating range starts just before the
- maximum brake force and ends in maximum,
for the unstable range then begins, in which
no further modulation is possible. The ABS
controls the regulation of the brake pressure
so that the brake force only becomes great
enough for a sufficient proportion of
cornering force to remain. With ABS we
remain in the Kamm circle as long as the car
is driving sensibly. We will leave driving
physics with these statements and turn to the
braking systems with and without ABS.
3) Basic ABS Control
Operation of ABS control unit
Applications of the ABS control unit The
signals produced by the wheel sensors are
evaluated in the electronic control unit. From
the information received, the control unit must
first compute the following variables:

- Wheel speed
- Reference speed
- Deceleration
- Slip

Reference speed
The reference speed is the mean, I.e. average speed of all wheel speeds determined by
simple approximation.

Simplified ABS control

If, during braking, one wheel speed deviates from the reference speed, the ABS control unit
attempts to correct that wheel speed by modulating the brake pressure until it again matches
the reference speed. When all four wheels tend to lock, all four wheels speeds suddenly
deviate from the previously determined reference speed. In that case, the control cycle is
initiated again in order to again correct the wheel speed by modulating the brake pressure.

Select Low control

This control is used for the rear axle. This controls the brake pressure on the rear wheels so
that the rear wheels will not be locked.
 4892-01

4) ABS Control Pattern

Vref: Reference speed

Vw: Wheel speed

The ABS control is performed by comparing the reference speed with each wheel speed. Firstly, it
is determined whether the vehicle is in the deceleration or acceleration state using the wheel
speed change ratio. Then, a signal is transmitted to the valve.
Finally, the brake pressure is adjusted via the signal.
6. HYDRAULIC CIRCUIT DIAGRAM

The vehicle equipped only with the ABS controls the wheel's braking force using three 3-channel
4-sensor method. The front wheels that are the primary circuit of the brake system is composed
of two wheel speed sensors and two channel valves system with two inlet valves and two outlet
valves. The rear wheels that are the secondary circuit of the brake system is composed of two
wheel speed sensors, one inlet valve and one outlet valve. This system is similar to the one from
the previous model.
 4892-01

7. HYDRAULIC CIRCUIT DIAGRAM IN EACH OPERATION

The hydraulic pressure in the master cylinder increases through the vacuum booster and it is
delivered to the wheel via the normal open inlet valve. At this moment, the normally-closed outlet
valve is closed. The speed of the wheel that hydraulic pressure is delivered reduces gradually .

As hydraulic pressure on each wheel increases, the wheel tends to lock. In order to prevent the
wheel from locking, the hydraulic valve modulator operates the inlet valve control solenoid to
close the inlet valve and stop the hydraulic pressure increases. At this moment, the outlet valve is
closed. This procedure helps the wheel to maintain a stable hydraulic pressure.
Even when the hydraulic pressure on each circuit is stable, the wheel can be locked as the wheel
speed decreases. This is when the ABS ECU detects the wheel speed and the vehicle speed and
gives the optimized braking without locking the wheels. In order to prevent from hydraulic
pressure increases, the inlet valve is closed and the outlet valve is opened. Also, the oil is sent to
the low pressure changer and the wheel speed increases again. The ABS ECU operates the pump
to circulate the oil in the low pressure chamber to the master cylinder. This may make the driver to
feel the brake pedal vibration and some noises

As the wheel speed increases, the inlet valve opens and the wheel's pressure increases due to
the master cylinder pressure. The oil in the low pressure chamber circulates to the wheel by the
pump and the wheel speed decreases as the hydraulic pressure at wheel increases. This
operation continues repetitively until there are no signs that the ECU is locking the wheels. When
the ABS hydraulic pressure control takes place, there may be some vibration and noises at the
brake pedal.

4. PRECAUTIONS

- The warning lamp flashes and warning beep sounds when the ESP is operating
When the ESP operates during vehicle movement, the ESP warning lamp on the instrument
panel flashes and beep comes on every 0.1 second. The ESP system is only a
supplementary device for comfortable driving. When the vehicle exceeds its physical limits, it
cannot be controlled.
Do not rely on the system. Keep on the safe driving.
- Feeling when ESP is working
When the ESP system activates, the feeling can be different depending on vehicle driving
conditions.
For example, you will feel differently when the ESP system is activated during the ABS is
operating with the brakes applied and when the brakes are not applied on a curve.
If the ESP system operates when the brake is applied, the brake pressure will be increased
on the corresponding wheel which already has braking pressure for the ESP controls.
- Noise and vibration that driver feels when ESP system is operating
The ESP system may transfer noise and vibration to the driver due to the pressure changes
caused by the motor and valve operations in a very short period of time. And, keep in mind
that the output and vehicle speed could be decreased without rpm increase due to the ASR
function that controls the engine power.

- ARP Operation
During the ARP operation, vehicle safety (rollover prevention) takes the first priority and thus,
stronger engine control is in effect. Consequently, the vehicle speed decreases rapidly, so
the driver must take caution for the vehicle may drift away from the lane.

- HDC is designed for driving on off-road steep grades (over 10%).

- Unnecessary usage of HDC can cause malfunctions inthe brake system or ESP. Do not use
HDC when drivingon normal roads.
- If driving on a level road with HDC on and ready foruse, HDC may be applied during sharp

normal roads.
- If the red HDC indicator illuminates, HDC is overheatedor malfunctioning. If the indicator is on
even after thesystem has cooled down enough, have the nearestauthorized dealer or service
center check the system.
- It is normal to have strong vibrations and noise fromthe brake system when HDC is applied.

1. ESP (Electronic Stability Program)

1) Overview
As the single-track vehicle model used for the calculations is only valid for a vehicle moving
forward, ESP intervention never takes place during backup.
The ESP system includes the ABS/EBD and ASR systems allowing the system to be able to
operate depending to the vehicle driving conditions.
Integrated functions in ESP system:
- HBA: Hydraulic Brake Assist System (Increases braking force)
- ARP: Active Rollover Protection System (Controls the engine output and braking force)
- HDC: Hill DescentControl System (Allows the vehicle to go down the steep hill slowly)

For example, when the brakes are applied during cornering at the speed of 100 km/h, the
ABS will operate at the same time the ASR or ABD systems operate to reduce the power from
the slipping wheel. And when yaw rate sensor detects the rate exceeding 4 degree/seconds,
the ESP system is activated to apply the brake force to the corresponding wheel to
compensate the yaw moment with the vehicle stability control function. This may cause a
problem in vehicle control system due to multi-operation of systems, thus there is a priority

3) Operation of ESP System
(1) Under steering

What is understeering?
Understeer is a term for a condition in which the steering wheel is steered to a certain angle
during driving and the front tires slip toward the reverse direction of the desired direction.
Generally, vehicles are designed to have understeer. It is because that the vehicle can return back
to inside of cornering line when the steering wheel is steered toward the inside even when the
front wheels are slipped outward.
As the centrifugal force increases, the tires can easily lose the traction and the vehicle tends to
slip outward when the curve angle gets bigger and the speed increases.

ESP controls during understeer

The ESP system recognizes the directional angle with the steering wheel angle sensor and senses
the slipping route that occurs reversely against the vehicle cornering direction during understeer
with the yaw rate sensor and lateral sensor. Then, the ESP system applies the braking force to the
rear inner wheel to compensate the yaw moment value. In this way, the vehicle does not lose its
driving direction and the driver can steer the vehicle as intended.
 4892-01

(2) Over steering

What is oversteering?

Oversteer is a term of a condition in which the steering wheel is steered to a certain angle during
driving and the rear tires slip outward losing traction.
Compared to understeering vehicles, it is hard to control the vehicle during cornering and the
vehicle can spin due to rear wheel moment when the rear tires lose traction and the vehicle speed
increases.

ESP controls during oversteer

The ESP system recognizes the directional angle with the steering wheel angle sensor and senses
the slipping route that occurs towards the vehicle cornering direction during oversteer with the
yaw rate sensor and lateral sensor. Then the ESP system applies the braking force to the front
outer wheel to compensate the yaw moment value. In this way, the vehicle does not lose its
driving direction and the driver can steer the vehicle as intended.
(3) ESP Operation
The ESP (Electronic Stability Program) has been developed to help a driver avoid danger of losing
control of the vehicle stability due to understeer or oversteer during cornering. The yaw rate
sensor, lateral sensor and longitudinal sensor in the sensor cluster and the steering wheel angle
sensor under the steering column detect the vehicle conditions when the inner or outer wheels are
spinning during oversteer, understeer or cornering. The ESP ECU controls against oversteer or
understeer during cornering by controlling the vehicle stability using input values from these
sensors and applying the braking force to the corresponding wheels independently. The system
also controls the engine power right before the wheel spin synchronized to decelerate the vehicle
automatically in order to maintain the vehicle stable during cornering.
 4892-01

(4) ESP controls during understeer

The ESP system recognizes the directional angle with the steering wheel angle sensor and senses
the slipping route that occurs reversely against the vehicle cornering direction during understeer
with the yaw rate sensor and lateral sensor. Then, the ESP system applies the braking force to the
rear inner wheel to compensate the yaw moment value. In this way, the vehicle does not lose its
driving direction and the driver can steer the vehicle as intended.

5) Hydraulic Diagram of ESP

When equipped with ABS, the braking force at each wheel will be controlled with 3-channel 4-
sensor method. And when equipped with ESP, 4 wheels will be controlled independently with 4-
channel method. (When controlling ABS system only, it will be operated with 3-channel method.)
When compared to the vehicle equipped with ABS/EBD only, the internal hydraulic circuit has a
normally-open separation valve and a shuttle valve in primary circuit and in secondary circuit.
When the vehicle brakes are not applied during engine running or when applying the non-ABS
operating brakes, the normally-open separation valve and the inlet valve are open, whereas the
normally-closed shuttle valve and the outlet valve are closed. When the ESP system is operating,
the normally-open separation valve will be closed by the solenoid valve operation and the
hydraulic circuit will be established by the shuttle valve. Then, the inlet and outlet valves will be
closed or open depending on the braking pressure increase, decrease or unchanged conditions.
For details, refer to "Hydraulic circuit by ESP operation range".
(1) ESP Hydraulic Unit in Idling and Bormal Braking Position

In this position, the separation valve and the inlet valve are open (normal open), the electrically
operated shuttle valve and the outlet valve are closed. When the brake is applied under these
conditions, the brake fluid will be sent to each wheel via the separation valve and inlet valve.
 4892-01

(2) When applied ESP (decreased pressure)

The pressure decreases just before the wheel speed drops and the wheels. The inlet valve closes
and the outlet valve opens as in the ABS HECU and the oil is gathered at the low pressure
chamber while no additional oil is being supplied. Then the pump operates to allow fast oil
drainage .
(3) When applied ESP (maintained pressure)

The Inlet valve and outlet valve will be closed to maintain the pressure in the hydraulic circuit
applied at the wheels. By closing the valves, the hydraulic pressure at the wheels will not be lost
or supplied any more. During ESP operation, the separation valve closes and only the shuttle
valve at the pump opens.
 4892-01

(4) When applied ESP (increased pressure)

The shuttle valve and inlet valve will be open and the separation valve and outlet valve will be
closed. Then, the pump is operated.
When ESP operates while the ABS is operating, the pressure will be increased continuously until
just before the corresponding wheel gets locked.
2. HBA (Hydraulic Brake Assist System)
1) Operation
The brake pressure value and the changed value of the pressure sensor are the conditions in
which the HBA System operates. There are 2 pressure sensors under the master cylinder. When
the ESP ECU system determines that emergency braking is present, the pump operates, the
brake fluid in the master cylinder is sent to the pump and the braking pressure is delivered to the
wheels via the inlet valves .
If the drive depress the brake pedal slowly, the pressure change is not high. In this case, only the
conventional brake system with booster is activated.
 4892-01

2) Purpose
HBA (Hydraulic Brake Assist) system helps in an emergency braking situation when the driver
applies the brake fast, but not with sufficient pressure, which leads to dangerously long braking
distance. ECU recognizes the attempt at full braking and transmits the signal calling for full brake
pressure from the hydraulic booster. An inexperienced, elderly or physically weak driver may
suffer from the accident by not fully pressing the brake pedal when hard braking is required under
emergency. The HBA System increases the braking force under urgent situations to enhance the
inputted braking force from the driver.
Based on the fact that some drivers depress the brake pedal too soft even under when hard
braking is necessary, the HECU system is a safety supplementary system that builds high braking
force during initial braking according to pressure value of the brake pressure sensor and the
pressure changes of the pressure sensor intervals.
When the system is designed to apply high braking force when brake pedal is depressed softly by
an elderly or physically weak driver, the vehicle will make abrupt stopping under normal braking
situation due to high braking pressure at each wheels.
3) Hydraulic Diagram of HBA

The above figure shows one front and one rear wheel and the same hydraulic circuit forms as in
the ESP operation.
When HECU recognizes that it is an emergency and it is required for hard braking, depending on
the pressure value of the brake pressure sensor and pressure changes caused by the pressure
sensor timing, it operates the pump immediately to apply the brake pressure at the wheels. Then,
the pressure in the pump increases until just before the corresponding wheel gets locked. The
motor still keeps rotating and the outlet valve and the separation valve are will stay closed. When
the wheel starts to lock, the HBA function cancels and switches to ABS operation
 4892-01

3. ARP (Active Roll-Over Protection)

1) Overview
The ARP (Active Roll-over Protection) system is a safety assistant device that minimizes, by
controlling brakes and the engine, the physical tendency of the vehicle rollover during sharp lane
changes or U-turns. For the system, software is added to the existing ESP system and no
additional device or switch is needed. One must note that the ARP system, just as general
assistant devices including the ABS, is only a safety assistant device using the ESP system and its
function is useless when the situation overcomes the physical power. Following picture shows how
the ARP compensates the vehicle position by varying each wheel's braking power to overcome the
physical tendency of the vehicle rollover during sharp turns.

The vehicle driving condition is controlled by the internally programmed logic according to the
input signals from wheel speed sensor, steering angle sensor and lateral sensor.
- During the ARP operation, vehicle safety (rollover prevention) takes the first priority and thus,
stronger engine control is in effect. Consequently, the vehicle speed decreases rapidly, so
the driver must take caution for the vehicle may drift away from the lane.
- The ARP function is still available even when turning off the ESP system by ESP OFF switch.
However, if the ESP system is shut off due to a system failure, the ARP system is also not
available.
 4892-01

4. HDC (HILL DESCENT CONTROL)

1) System Overview
The HDC system is an automatic descent control device that allows the vehicle to automatically
decelerate to about 7 km/h by 0.1G, on steep roads (slope level exceeding 10%) through a
separately installed switch operation.
When the vehicle speed reaches below 7 km/h (refer to the information below), the HDC
automatically terminates the operation.

gradient.

The G sensor in sensor cluster measures the actual gradient of roads. However, it may
recognize a sharp turn or rough road as a steep downhill with over 10% of gradient. Thus, it
may cause an operation of HDC system.
3) Operating Description
(1) HDC (Hill Descent Control) System Operating Conditions
HDC is operable only when the conditions below are met:
a. When HDC switch is turned ON
b. Gearshift lever position (Forward/Reverse)
Automatic transmission: operates in any position except for P (parking) or N (neutral) positions.
c. When not depressing the accelerator pedal or brake pedal.
d. The vehicle speed is above 7 km/h (in Automatic transmission/4H mode).

The vehicle conditions in Step (d) are subject to the vehicle driving conditions. Refer to below:
A. Speed available in HDC mode (slope)
- 2H/4H mode: vehicle speed below 50 km/h
(operation slope level: 10%, termination slope level: when it reaches 8%)
- 2H/4H mode: vehicle speed below 50 km/h
(operation slope level: 8%, termination slope level: when it reaches 5%)
B. HDC target speed in 2H/4H mode
(The HDC target speed is the speed that the HDC is not terminated even after the vehicle
speed reaches 7 km/h, but is converted to the stand-by mode. When the vehicle speed
increases again as a result of the increase of the road steepness, etc., the HDC goes into
operation.)
- Forward driving: 7 km/h
- Reverse driving: 7 km/h (automatic transmission), 8.5 km/h (manual transmission)

e. Vehicle position control function in ESP and HBA function are not in operation:
- The HDC is the device to improve the engine brake effect during downhill driving on a steep hill.
- If the ESP function is in operation, HDC operation is overridden.
f. The gradient of downhill should be over 10%.
- When the gradient of downhill exceeds 10%, the HDC operates until the vehicle speed reaches
speed 7 km/h.
- The HDC returns Ready status when depressing the accelerator pedal or brake pedal during its
operation. When releasing the pedal, the HDC resumes the operation. Therefore, the driver can
control the vehicle speed as desired.

When the slope level is between 10% and 20% during the HDC operation

- When depressing the accelerator pedal or brake pedal, HDC system is changed to stand-by
mode. When depressing the accelerator pedal again, HDC starts its operation again. Therefore,
drivers can control the vehicle speed to a desired level by operating the accelerator pedal.

When the slope level exceeds 20% during the HDC operation
 4892-01

The percentage for gradient as below:

ex)

* 1G = 9.8 m/s : acceleration

In other words, the gradient of 10% means that a road has 10 m of width and 1 m of
altitude from level ground.

(2) HDC (Hill Descent Control) System Non-Operation Conditions

The HDC stops its operation when any of conditions below occurs:
a. When HDC switch is turned OFF
b. Gearshift lever has passed neutral (N) position.
Vehicle with automatic transmission: Sensing at the selector lever unit
c. When the vehicle speed is out of the specified values. (Below 7 km/h )
d. When the ESP related functions, e.g. vehicle position control, HBA, ARP is activated during
HDC operation.
e.
a steep hill with HDC operated.
There is no specific temperature sensor in the system, but a programmed logic inside the
HECU predicts the temperature based on the operating numbers and conditions of HDC.
f. When the slope level is below 10%

even where the HDC warning lamp blinks.

(4) Operation of HDC Indicator Controller

This table describes the coming-on and blinking mode of HDC indicator according to the HDC
switch operation (ON/OFF).
The HDC indicator on the instrument panel has two modes; green (function lamp) and red
(warning lamp). The HDC switch is a push & self return type switch ? when you press it once, it
starts to operate and when you press it again, it stops the operation.

Basically, the brake system's basic functions can work even when there are problems with
the HDC system.
As given in the table above, the HDC warning lamp comes on when:
- Initial ignition ON
- HDC system error occurs
- Brake system overheat
(5) Warnings for HDC Operation
HDC system is a supplemental system for brake system. The operating conditions should be
kept. The operating noise is much different from that from ABS/ESP system.

Make sure to remember the warning conditions below:

- The HDC system has been developed to enhance the driving safety on steep downhill.
Therefore, avoid using the HDC system on level roads.
- If the HDC system is used frequently, the internal components of ESP HECU and related
parts could be damaged.
- Place the HDC switch at OFF position while the vehicle is driving on level; roads. As
mentioned earlier, the HDC system is operable even when the vehicle is driving on level
roads. This could cause the driver to lose control of the vehicle resulting in an accident.
- The heavy noise from HECU and brake system during HDC operation is normal operating
conditions and is not hazardous.

1. SYSTEM DESCRIPTION
The power steering has been designed to make the wheel move more easily than in a manual
steering system. The hydraulic power assists the process utilizing hydraulic fluid. The fluid
increases pressure in the power steering pump and aids the movement of the steering
mechanism. The power steering system consists of pump, oil reservoir, rack and gear box. The
power steering pump is a vane type and delivers hydraulic pressure to operate the power steering
system. The pressure relief valve in the pump controls the discharging pressure. The rotary valve
in the rack and the pinion gear directs the oil from the power steering pump to one side of the
rack piston. The integrated rack piston converts the hydraulic pressure to linear movement. The
operating force of the rack moves the wheels through the tie rod, the tie rod end and the steering
knuckle. Even though the hydraulic pressure cannot be generated, a driver can steer the vehicle
without power assist but it needs very high steering force. In this case, the operating force of the
steering wheel is conveyed to the pinion, and the movement of the pinion moves the rack through
the pinion gear combined to the rack gear.

2) ECPS Configuration
1. PCV (Pressure Control Valve)
This valve controls the hydraulic pressure supplied to reaction device by moving the spool
valve according to the changes of solenoid valve.
2. Reaction device
This device increases the steerability effect by binding the input shaft with supplied hydraulic
pressure from PCV.
3. Solenoid valve
This valve determines the valve spool position in PCV with the electric current supplied from
ECPS control unit.

3) Operation of Solenoid Valve

SSPS control unit controls the current to solenoid valve according to the vehicle speed. Based on
this current, the solenoid valve changes the position of valve spool to control the hydraulic
pressure to the reaction plunger. Accordingly, the SSPS system can get the desired steering force
according to the vehicle speed.

1. SSPS control unit outputs nearly maximum electrical current.

2. The solenoid rod pushes PCV spool to right side.
3. The hydraulic pressure coming from pump is not supplied to the reaction device as the spool
orifice is cut off.
4. The hydraulic pressure is cut off and the manipulation of steering wheel becomes lighter.
 4620-01

1. The shaft operation force of solenoid rod is reduced due to the reduction of output current
from SSPS control unit.
2. The coil spring pulls the PCV spool toward solenoid valve to open it.
3. The hydraulic pressure from pump flows to pinion reaction area through orifice and applies
reaction force to reaction plunger.
4. At this time, the reaction plunger transmits the reaction force to V-groove in input shaft to
provide heavy steerability.
4) System Control
ECPS system, according to the vehicle
speed, enables to achieve proper steering
characteristics by controlling hydraulic
pressure to reaction plunger located in input
shaft of power steering gear box. In other
words, ECPS control unit enhances the
parking conveniences by controlling duty type
current control. It provides heavy steerability
with low current as the vehicle speed
increases. And, it provides light steerability
with high current as the vehicle speed
decreases.

During parking and driving in low speed, the control unit supplies approx. 1 A of electric current to
solenoid valve. Then, the spool located in PCV compresses the upper spring and elevates upward
and, the working pressure from oil pump (A port) is not able to flow to the reaction plunger (C
port). As a result, the pressing force from reaction plunger disappears and the steerability
enhances.
 4620-01

During high speed driving, the control unit supplies weak electric current to solenoid valve. Then,
the spool located PCV moves from top to bottom, and the working pressure (A port) from oil
pump is applied to reaction plunger (C port ) through B port. As a result, the pressing force from
reaction plunger against input shaft is increased and the steerability becomes heavier.

significantly under-inflated or over-inflated.Driving on a significantly under-inflatedtire causes the
tire to overheat and canlead to tire failure. Under-inflation alsoreduces fuel efficiency and tire

The wheel module is located under valve body in each tire and periodically sends the data to
TPMS ECU with radio frequency. TPMS ECU converts the signals and sends them to the meter
cluster through CAN line so that the driver can recognize the tire conditions. TPMS ECU can
identify the positions of wheel module in each tire.

7. TIRE PRESSURE INDICATION PROCEDURE
The TPMS ECU receives the tire pressure value from the wheel module with radio frequency at
every 30 seconds and sends the signal to meter cluster via CAN line to show it to driver.

To reduce the battery current consumption, in normal driving conditions, each wheel module
sends the tire pressure and temperature with its own ID (Identification) to TPMS ECU at every
30 seconds.
However, in emergency situation (e.g., pressure drop of 1 psi a second), it sends the data to
TPMS ECU at every one second. In this case, the batter current consumption increases
dramatically. Have the system check immediately.

Tire Pressure Indication Procedure (Simultaneously processed)

8. TIRE INFLATION PROCEDURE

1) Overview
A tire equipped with wheel module should be inflated in a unique method other than conventional
one. As the tire pressure on tire pressure gauge and could be different from the value displayed
on meter cluster, the tire pressure should be checked and adjusted after specific period
(transmitting time for wheel module). In addition, the displayed value could be changed after
driving even if it was set to the specified value.

2) Tire Inflation Procedure

A. Park the vehicle on a level ground and let everyone get off the vehicle.

- If there is another vehicle equipped with the TPMS, keep the distance from this vehicle at
least 5 m to prevent interference of wheel module transmitting.
- Unload the cargo if not necessary.
- Even though you adjusted the tire pressure, the changed value cannot be displayed on
the meter cluster immediately because the wheel module sends the data with a specific
interval. And, if there are interfering conditions for radio frequency such as other vehicles
equipped with TPMS around the vehicle and severe weather changes, the indication
needs few minutes to be displayed.

Carefully explain the TPMS system and its usage to customers. The tire pressure can be
changed frequently due to driving conditions, passengers, internal temperature changes and
loads.
B. Tire Inflation and Inspection for Tire Pressure

2) Typical Inspection
1. Tread
Inspect the tread condition on the tire
surface and various damages resulting
from the foreign materials, crack, stone or
nail etc. If there is any damage in the tire,
repair or replace it.

2. Wear limit
- Measure the depth of the tire tread. If
the depth of the tread is below the
specified value, replace the tire

Wear limit 1.6mm

- You can see the protruded part in the

is the indicator of the tread wear limit.

The limit of the tread wear for all season
- tires are 1.6 mm, which is the same as
the general tires, but the wear limit mark

- Higher than recommended pressure can cause hard ride, tire bruising or damage and rapid
tread wear at the center of the tire.
- Excessive tire wear over the limit of the tread wear (1.6 mm) can cause lower sliding friction
due to longer braking distance, easy tire burst by foreign materials, tire hydroplaning, and
tough brake and steering wheel handling.

4. Wheel runout
If wheel runout or tire runout is excessive,
it could result in abnormal wear of the tire.
Measure the runout with a dial gauge.
- Measure the dial runout and lateral
runout on both the inboard and
outboard rim flanges.

Specified value 2.66mm

- Measure free radial runout on the tire

tread.

Specified value 2.03mm

- If any measurement exceeds the above

specifications, replace the applicable
tires or wheels
 4170-34

5. Wheel balance
- Check the wheel balance when the
wheel is unbalanced or the tire is
repaired.
- The total weight of the wheel weight
should not exceed 150 g.
- Ensure that the balance weight installed
is not projected over 3mm from the
wheel surface.
- Use the specified aluminum wheel
balance weights for aluminum wheels.
- Weight balance can be added by 5 g.
There are two types of weight balance,
tape type and adhesion type.

- Make sure to read the manual of the

manufacturer thoroughly before using
wheel balance tester.
Regular Tire
6. Change tire location
To avoid uneven wear of tires and to
prolong tire life, inspect and rotate your
tires every 5,000 km.

Regular Tire
Mixing tires could cause the driver to lose
control while driving. Be sure to use the
same size and type tires of the same
manufacturer on all wheels. Otherwise, the
rack stroke (maximum transverse
distance) of the steering gear could be
changed.
1. OVERVIEW
A radial tire uses a cord angle of 90 degrees. That is, the cord material runs in a radial or direct
line from one bead to the other across the tread. In addition, a radial tire has a belt overwrap
under the tread surface to provide greater structural stability. The belt overwrap of a radial tire
distortion while the radial structure enables high speed driving.
Tire supports the weight of the vehicle, reduces the impact from the road and at the same time,
transmits the power to propel, brake and steer on the road. It also functions to maintain a

vessel of air.
There is wear limit mark on the tire, which protrudes as a strip shape located approximately 1.6
mm from the groove bottom. This wear limit mark is not seen from the outside so there is

groove depth, measure at any point other than the point which has a wear limit mark.
The tire is worn unevenly according to the driver's driving habit, improper servicing, low tire
inflation pressure, changed tire location, etc.

 Structure of Tire

Tread
This thick layer of rubber provides the interface between the tire and the road. Wear-resistant
rubber is used to protect the carcass and belt against fractures and impacts and to deliver a long
driving life.

Shoulder
Located between the tread and sidewall, the shoulder rubber is the thickest so that the design
must allow for the easy diffusion of heat generated within the tire while driving.

Sidewall
The part between the shoulder and bead, the flexible sidewall protects the carcass and enhances

characters are indicated here.

Bead
The bead attaches the tire to the rim and wraps the end of the cord fabric. Comprised of the
bead wire, core, flipper and other parts, the bead is generally designed to be slightly tight around
the rim so that in the case of a sudden drop in inflation pressure, the tire will not fall off the rim.

Carcass
As the most important framework of a tire, the entire inner layer of cord fabric is called the
carcass. The carcass acts to support air pressure, vertical load and absorb shocks.

Belt
The belt is made by steel wire. This reduces the impact from the road and provides the wide
tread.

resulting in increased life.
2. ABNORMAL TIRE SYMPTOM
Standing Wave

Specified tire inflation pressure 32psi

During driving, the rotating tire repeats deformation and restoring movement in is tread. This
happens when the tire pressure is low in high speed driving.
However, when the wheel rotating speed is fast, the tire is deformed even before it is restored to
its original shape and the trembling wave appears on the tread portion. If this symptom lasts for
an extended period of time, the tire can be blown out in a short period of time.
If the standing wave symptom occurs on the tire, rubber on the tread comes off and eventually
the tire can be blown out which is very dangerous. When driving at high speed, the inflation
pressure should be increased to decrease heat generation due to extension and contraction
motion, to decrease hydroplaning and to prevent standing wave.
To prevent this symptom, it is recommended to increase the tire pressure 10 ~ 30 % higher than
the specified pressure value in high speed driving.

Tire Pressure vs. Tire Life

 4170-34

Hydro Planing

Vehicle speed = 80 km/h

No Hydro planning Partial Hydro planning Full Hydro planing

When the vehicle is driven on a road surface covered with water at high speed, tires do not
contact with the road surface but rotate floating on a thin film of water.
It causes brake failure, lower traction force and losing the steering performance.
To prevent this, increase the tire inflation pressure, use tires with leaf shape tread which is not
worn. However, it is a best measure to drive slowly.
3. WHEEL BALANCE
If weight is not equally distributed around the wheel, unbalance centrifugal force by the wheel
rotation produces vibration. As the centrifugal force is produced proportional to the square of the
rotating speed, the wheel weight should be balanced even at high speed. There are two types of
the tire and wheel balancing: static and dynamic. Abnormal vibration may also occur due to
unbalanced rigidity or size of tires.

Static Balance

When the free rotation of the wheel is

allowed, the heavier part is stopped on the
bottom if the wheel weight is unbalanced and
this is called "Static Unbalance". Also, the
state at which tire's stop position is not same
Center is called "Static Balance" when the wheel is
rotated again. If the part A is heavier as
shown in the figure 1, add the balance weight
of a weight corresponding to unbalanced
weight from B to A to maintain the static
[Figure 1]
balance. If the static balance is not
maintained, tramping, up and down vibration
of the wheels, occurs.

Dynamic Balance
The static unbalance of the wheel creates the
vibration in the vertical direction, but the
dynamic unbalance creates the vibration in
the lateral direction. As shown in the figure 2
(a), if two parts, (2) and (3), are heavier when
the wheels are under the static balance
condition, dynamic unbalance is created,
resulting in shimmy, left and right vibration of
the wheels, and the torque Fxa is applied in
the axial direction. To correct the dynamic
unbalance, add the balance weight of a same
weight for two points of the circumference of
the rim, A and B, as shown in the figure 2 (b),
and apply the torque in the opposite direction
(a) (b) to the torque Fxa to offset in order to ensure
smooth rotation of the wheel.
[Figure 2]
 4170-34

4. WHEEL ALIGNMENT
Wheel alignment consists of adjusting the angles of the wheels so that they are parallel to each
other and perpendicular to the ground, thus maximizing tire life and ensures straight and true
tracking along a straight and level road.

In automotive engineering, toe, also known as

tracking, is the symmetric angle that each
wheel makes with the longitudinal axis of the
vehicle, as a function of static geometry, and
kinematic and compliant effects. This can be
contrasted with steer, which is the anti-
symmetric angle, i.e. both wheels point to the
left or right, in parallel (roughly). Positive toe, or
toe in, is the front of the wheel pointing in
towards the center line of the vehicle. Negative
toe, or toe out, is the front of the wheel
pointing away from the center line of the
vehicle. Toe can be measured in linear units, at
the front of the tire, or as an angular deflection.

Camber is the angle made by the wheels of a

vehicle; specifically, it is the angle between the
vertical axis of the wheels used for steering
and the vertical axis of the vehicle when
viewed from the front or rear. It is used in the
design of steering and suspension. If the top
of the wheel is farther out than the bottom (that
is, away from the axle), it is called positive
camber; if the bottom of the wheel is farther
out than the top, it is called negative camber.

Camber angle alters the handling qualities of a particular suspension design; in particular, negative
camber improves grip when cornering. This is because it places the tire at a better angle to the
road, transmitting the forces through the vertical plane of the tire rather than through a shear force
across it. Another reason for negative camber is that a rubber tire tends to roll on itself while
cornering. Negative camber can also be caused by excessive weight on the front wheels. This is
commonly seen on modified cars with larger engines than standard; the weight of the modified
engine can make the wheels negatively camber. The inside edge of the contact patch would begin
to lift off of the ground if the tire had zero camber, reducing the area of the contact patch. This
effect is compensated for by applying negative camber, maximizing the contact patch area. Note
that this is only true for the outside tire during the turn; the inside tire would benefit most from
positive camber.
Caster is the angle to which the steering pivot
axis is tilted forward or rearward from vertical,
as viewed from the side. If the pivot axis is
tilted backward (that is, the top pivot is
positioned farther rearward than the bottom
pivot), then the caster is positive; if it's tilted
forward, then the caster is negative.
Positive caster tends to straighten the wheel
when the vehicle is traveling forward, and
thus is used to enhance straight-line stability.
The mechanism that causes this tendency is
clearly illustrated by the castering front wheels
of a vehicle. The steering axis of a vehicle
wheel is set forward of where the wheel
contacts the ground. As the vehicle is driving
forward, the steering axis pulls the wheel
along, and since the wheel drags along the
ground, it falls directly in line behind the
steering axis. The force that causes the wheel
to follow the steering axis is proportional to
the distance between the steering axis and
the wheel-to-ground contact patch-the
greater the distance, the greater the force.
This distance is referred to as "trail."

- "Compression -> Condensation -> Expansion -> Evaporation"

(2) Functions

Condition: Gas
Function: Circulates the refrigerant and increases the pressure and temperature for easier evaporation.

Condition: Gas/Liquid
Function: Cools and condenses the refrigerant by using ambient air to liquefy it under high
pressure.

Condition: Gas/Liquid
Function: Keeps the refrigerant free from moisture by separating/collecting the moisture from it.

Condition: Liquid/Liquefied gas

Function: Performs adiabatic expansion and flow control for easier evaporation.
 6822-11

Condition: Liquefied gas/Gas

Function: Cools the air by absorbing the heat from the air around the evaporator.

(3) Description for Each Cycle

- The evaporated refrigerant in the evaporator enters to the compressor. And the refrigerant gas
is compressed until it can be liquefied at ambient temperature.
- Thus, the low refrigerant pressure is maintained so that the liquid refrigerant can be evaporated

- The high pressure and high temperature gas (refrigerant) from the compressor is cooled down
by the fresh air entered into the condenser. Then, this gas is converted to liquid and collected
in the receiver drier.
- The heat generated from the high pressure refrigerant is dissipated to the ambient air, and it is
called "heat of condensation".
The heat of condensation is the summation of the heat of vaporization (heat that the refrigerant
absorbs from the inside of the vehicle) and the calorific value converted from the amount of
work which is needed to compress.

- The liquid refrigerant lowers the pressure making its evaporation easily accomplished.
- This process (lowering the pressure to the level at which evaporation easily takes place before
the liquid refrigerant is sent to the evaporator) is called
"Adiabatic Expansion".
- During adiabatic expansion, the expansion valve lowers the pressure of the refrigerant and
determines the correct amount of refrigerant going into the air conditioning evaporator.
- That is, the amount of heat, which is needed to stop the evaporation, is determined according
to the cooling load.
- The expansion valve detects this and regulates the amount of the refrigerant exactly.

- The refrigerant is converted from liquid to gas in the evaporator.

(The refrigerant in the form of fog in the evaporator is vaporized actively)
- At this time the refrigerant, in the form of liquid, absorbs the heat in the air which is need for
evaporation (latent heat) and is cooled down. Then the blower blows the cooled air inside the
vehicle to lower the temperature.
- There are liquid refrigerant from the expansion valve and evaporated refrigerant in the evaporator.
The evaporation temperature can be predicted from the evaporation pressure (i.e. relationship
- between saturation pressure and saturation temperature).
It is important to keep the pressure inside the evaporator low, so that the refrigerant is evaporated
- at low temperature to make sure the completely evaporated refrigerant is entered into the
compressor.

- Do not diagnose the circuit with a circuit tester. Do not attempt to modify any air bag
components including the steering wheel, air bag mounting area, and harness.
- Do not impact any air bag components including the steering wheel, air bag mounting area,
and harness by hand or tools. You may get injured by sudden deployment.
- The air bag components will be very hot after deployment. Do not touch them.
- Once the air bag system is triggered, the triggered air bag assembly should be removed from
the vehicle and replaced with new one.
- The air bag contains explosive materials, so contact Ssangyong Dealer or Ssangyong
Authorized Service Operation when trashing or replacing it.
- Incorrect air bag inspection can be dangerous and cause injuries. The air bag system must be
disposed only by Ssangyong Dealer or Ssangyong Authorized Service Operation.
- Replace the steering wheel with only Ssangyong genuine part.
- When the engine starts, the air bag warning lamp comes on for a system check. It goes out
after 3 to 7 seconds when the system is normal. If this warning lamp stays ON, then the system
may be defective. Have the air bag system checked immediately by Ssangyong Dealer or
Ssangyong Authorized Service Operation.
- The seat belt and air the bags are the most effective when you are sitting well back and upright
in the seat.
- A child restraint system must not be placed on the front seat. The infant or child can be
severely injured by an air bag inflation in case of an accident.
- Do not carry your child on your lap while driving. You cannot resist against the impact pressure
in an accident.
The child could be crushed between you and the parts of the vehicle.
- Do not place any objects on the air bag inflation location. You may get injured by those objects
during deployment.
- Do not attach any objects such as a sticker, scent bottle, or phone holder on the steering
wheel pad and to the dashboard.
- Do not put the seat cover on the front seatbacks. It may interfere with the side air bag inflation.
When sitting in the rear seat, do not hold onto the seatback of the front seat. If the side air bag
- inflates, the occupant may get seriously injured.
Do not lean on the door. When the side air bag inflates, the occupant may get seriously
- injured.
Do not place any objects such as an umbrella or a bag between the side air bag and the door.
- Do not place the part of your body near the side air bag. You may obstruct the side air bag or
get injured by the inflation impact.
 - Do not slam the front doors. It may lead to an unintended inflation of the side air bag.
- Do not move your seat too close to the steering wheel or dashboard. If you lower your head,
the air bag can hit your head during inflation and can cause severe injury or even death.
- Hold only the outer rim of the steering so that the air bag can inflate without any hinderances.
- Do not place your face or chest near the steering wheel and dashboard. Also, do not allow
anyone to place their hands, leg or face on the dashboard. The air bag cannot work properly.
- Do not hold and operate the steering wheel by crossing your arms. You could get seriously
injured when the air bag deploys.
- When the air bag inflates, it makes a loud noise and smoke. However, the smoke is a non-toxic
nitrogen gas.
- When the air bag is deployed, non-toxic gas will come out. This gas may cause skin, eyes or
nose irritation.
Wash it out with cold and clean water and consult the doctor if irritation continues.
- When any repairs are needed for the steering wheel, or when an accident occured without the
air bag deployment, have the air bag system checked by Ssangyong Dealer or Ssangyong
Authorized Service Operation.
- The windshield glass may be broken when the passenger's air bag is deployed.
- The air bag deployment can cause abrasion on your hands and face.

1) Front Air Bag System

The air bag deploys when:

- A front collision occurs, which occupants cannot be protected by seat belt.

The air bag can deploy when:

- Underbody impact from the road surface, impact against the curb at a very high speed, or
dropping impact onto the road surface with a large angle occurs.

The air bag does not deploy when:

- The vehicle rolls over or tips over sideward, or a side/rear collision occurs.
- the impact of the collision is low enough for the seat belt to protect the occupant properly.

Seldom oeprate
- A collision to diagonal direction (not a front collision) occurs or the vehicle tips over.
- A weak collision, which the sensor cannot detect, occurs (under the activation
requirements).
- A collision against narrow objects such as a telegraph pole or a tree occurs.
- The vehicle falls into a drainage or a puddle.
- The front of the vehicle crashes into high impact point vehicle such as a truck.
- The hood is hit by falling stones.
- The air bag warning lamp is on.
 8810-00

2) Side Air Bag System

Driver's Passenger's

The curtain air bags are installed to the upper end of both doors. The air bags provide head
protection for the front and rear outboard occupants in a side collision.

The air bag deploys when:

- a severe oblique collision occurs with a specific severity, angle, speed, and position.

The air bag can deploy when:

- the vehicle rolls over or tips over sideward with a severe impact.
- The vehicle is stationary or a front collision occurs with low speed.
- A rear collision occurs.
- The impact of the collision is low enough for the seat belt to protect the occupant properly.
The air bag does not deploy when:
- The vehicle is stationary or a front collision occurs with low speed.
- A rear collision occurs.
- The impact of the collision is low enough for the seat belt to protect the occupant properly.
Seldom oeprate
- A collision with oblique impact to the front seat direction or a front collision to the diagonal
direction occurs.
- a frontal or rear collision occurs.
- The vehicle rolls over or tips over sideward with minor impact.
- The air bag warning lamp is on.

- The overall air bag operation process and its functions and roles are broadly explained in this
block diagram. This diagram summarizes and highlights the functions adopted by Ssangyoung
Motors.
8810-00
5. DEPLOYING CONDITIONS
- Once the ignition starts, the SDM starts to diagnose the air bag system during the ignition
process.If the system is OK, the SDM is armed for a specific impact on the vehicle. The
ignition time takes about 6 sec.

6. DEPLOYMENT
1) Air Bag System Deployment (Firing Loop)
- According to the collision deceleration rate that each collision G sensor reads, the air bag unit
sends out about 2~4 or higher Amp current. This current generates some heat, which fires the
detonator in the inflator.

The table shows the basic inner resistance of the air bag related module and the basic instant
current necessary for firing.

Seat belt Driver/Passenger side ai

Air bag module DAB /PAB
pretensioner(BPA) bag module

Firing current 1.2 Amps 1.2 Amps 0.8 Amps

- Please do not connect a tester to any air bag connector or single item to measure the
supplied power or resistance. The detonator may explode due to a sudden extra power
supplied by the tester.
- Before removing or installing any air bag related components, disconnect the negative
battery cable.

2) Air Bag Deployment Signal Output (Crash Out)

For the safety reason, the system outputs the air bag deployment signal to STICS to unlock the
doors automatically.

Automatic Door Unlock (Crash unlock: unlock when colliding)

- The air bag collision signal input cannot be accepted within 7 seconds after turning the
ignition key to "ON" position.
- After this period, the door lock system outputs "UNLOCK" for all doors for 5 seconds from 40
ms after receiving the air bag collision signal.
- Even though the key is turned to "OFF" position during the output of "UNLOCK", the output
continues on for remaining period.
- The function is erased when turning "OFF" the ignition switch.

Cautions for Door Lock/Unlock Control

- The "Unlock" control by air bag signal prevails over any "LOCK" or "UNLOCK" control by
other functions.
- The "LOCK/UNLOCK" request by other functions will be ignored after/during the output of
"UNLOCK" by the air bag.However, the door lock is controlled by other functions when the
ignition switch is "OFF".

7. AIR BAG WARNING LAMP OPERATIONAL CONDITIONS

The air bag warning lamp on the instrument panel has a few operational conditions. The following
are the conditions:

When Turning the Ignition Switch to ON Position Initially

The air bag unit performs a turn-on test when the ignition is turned on initially. The air bag unit
flashes the air bag warning lamp 6 times at 1 Hz interval. After that, the air bag warning lamp will
go off if no malfunction have been detected.

1. WARNINGS FOR POWER SEAT

1. Adjust the driver's seat before driving.
2. Make sure that the seat is firmly secured after adjusting.
3. Never drive the vehicle with the head restraint removed or lowered excessively. Otherwise,
your neck, spine or other parts of the body can be severely injured in the event of an
accident.
4. If you recline the seatback excessively, you could slide under the seat belt and be injured
severely in a collision.
5. Do not put any object that could damage the seat on the seat.
6. The front and rear seats are equipped with the heated wire (seat warmer) system. Using the
seat warmer system excessively may cause minor burns. The following occupants should
exercise special care when using the heated wire seat.
- Infant, child, old or handicapped person
- Person with sensitive skin
- Exhausted person
- Persons who is drunk or took medicine which causes drowsiness such as sleeping
pills, cold tablets, etc.
7. Do not place anything on the seat that insulates against the heat, such as a blanket or
cushion.
8. Make sure that the head restraints are in place and secured properly. Never drive the vehicle
with the head restraint removed.
9. To minimize the injuries in a collision or an abrupt stop, make sure the seatback is in the
upright position before driving. If the seatback is reclined too much, the occupant could slide
under the seat belt in a collision or an abrupt stop and cannot be protected properly by the
airbag system.

2. CAUTIONS FOR POWER SEAT

1. You can operate the power seat with the ignition switch OFF. However, frequent operation of
the seat switch with the engine stopped can result in battery becoming discharged.
2. Operating more than one seat adjustment switch at the same time can cause damage to the
seat motor. Therefore, operate the seat switch only one at a time.
3. Do not use organic solvents such as benzene, thinner, alcohol or gasoline to prevent the seat
cover from being damaged while cleaning.
4. Do not operate the seat position adjustment switch forcefully when the seat does not move or
it contacts an object.
5. If the power seat is not operated, check and correct the problem before driving off.
