EMERGENCY INFORMATION
DRAFT
Emergency Service Brakes
This coach is equipped with a dual-circuit service brake system with separate reservoirs for rear and front brakes
to ensure that brakes are available if one circuit fails. If a low air pressure occurs in the primary service brake
supply circuit, secondary service brake air is routed to the emergency stand-by valve. Fully modulated primary
(rear) braking will be available through the drive axle brake chamber's emergency portion, along with the
secondary (front) service brakes.

Emergency Parking Brakes

The parking brake emergency release button allows the coach to be moved to safety if both
brake reservoirs are depleted and the parking brake has applied automatically. DO NOT use
this feature other than to move the coach to a safe parking location. DO NOT drive the coach
until the air loss problem is fixed and the brake reservoirs are fully charged.

If the front and rear brake system air pressure falls below approximately 40 ± 5 psi (276 ± 35 kPa), the parking
brake will automatically apply. An isolated emergency release reservoir has enough air to release the parking
brake three times. Press and hold the emergency parking brake release button (LH console switch panel). The
parking brake springs will reapply as soon as the knob is released. See "Figure 12: Emergency Parking Brake
Release" on page 12.

 DRAFT EMERGENCY INFORMATION

Air Pressure - Warning

In the event of a low air warning, stop the coach at once and DO NOT operate the coach until
the air loss is fixed and the low air alarm is silenced.

The coach should not be operated with air pressure below 100 psi in either gauges, as brake
effectiveness could be reduced resulting in an increased stopping distance.

Individual air pressure gauges are used to monitor the coach’s front (secondary) and rear (primary) air brake
systems. An LED indicator in each of the gauges illuminates and a warning alarm sounds (constant beep) if air
pressure drops below 70 psi (483 kPa). Warnings will remain on until air pressure rises above 95 psi (655 kPa).

Brake System Emergency Fill

Emergency fill provisions allow the primary or secondary service reservoirs to be filled independently. The fill
provisions are in the front roadside service compartment. See "Figure 13: Emergency Fill" on page 13.

Coach Air Service

A service fill / supply connection provision is located behind the curbside service door and the front roadside
service compartment. This allows filling/supplying the coach air system from an external source, provided that
the air system is intact. Coach air service “FILL” can also be used at the WHOLE COACH AIR CONNECTION
port. See "Figure 14: Air Fill / Air Supply" on page 14.

2. Apply parking brake and turn on hazard lights.

3. Obtain and place reflector triangles in front and behind the coach. Signal flares are provided in a cylindrical
case above the reflector triangles case. See "Figure 15: Reflector & Signal Flare Location" on page 15.

Hazard Signal System

The coach is equipped with a Flashing Signal System which flashes all directional signal lights simultaneously to
warn traffic in an emergency. The Hazard Warning Lights switch is used to acctivate this Signal System. A
Hazard indicator light is illuminated and both turn-indicator arrows flash when the system is operating. See
"Figure 16: Hazard Signal System" on page 15.

The Hazard Warning lights automatically activate when the passenger door opens, the Wheelchair toggle switch
(if equipped) is in the ON position or when Reverse [R] gear is selected. The lights extinguish when the

Brake application is proportional to the amount of pedal pressure applied. Applying the brake pedal
illuminates the stoplights and the stop indicator. See "Figure 53: Foot Controls" on page 62.

Fanning or pumping the brake pedal is not recommended. This practice reduces the effectiveness of
the Brake System and interferes with the ABS System. It also wastes air and causes unnecessary
wear on the brake parts.

DO NOT press on the accelerator pedal before or during starting, this is unnecessary to start
the engine and could damage the Electronic Control Systems.

5. Accelerator Pedal - The accelerator pedal is located to the right of the brake pedal and controls the engine
throttle. The speed of the engine is proportional to the amount of pedal movement being applied downwards.

360° Camera System (Optional)

Due to the nature of this system, objects may not appear exactly as their real location with
respect to the coach body. Object may appear physically closer than they appear.

The 360° Camera System includes four (4) exterior cameras designed to help reduce operator blind spots by
providing a real time view of the area surrounding the coach on a single view. A simulated bird’s-eye view of the
coach and its surroundings provides the operator with visual assistance.

The LCD screen can show a single full-screen view or split-screen view. See "Figure 54: 360° Camera System"
on page 63. The system is configured to automatically display certain views when the coach is in Reverse [R]
gear, and when turn signals are engaged. Pressing the 360° Camera switch on the LH console will let you toggle
through each individual view of the front, rear, left or right. The display screen will shut off automatically if the
speed of the coach is 17 mph and above.

The 360° Camera System cameras are connected to the Video Surveillance System which is capable of capturing
the real-time events to a Digital Video Recorder (DVR) for later viewing.

Operational Checklist

Before starting the engine, ensure that FAST IDLE feature is OFF and the parking brake is
applied.

1. While the engine is running, look for oil or coolant leaks, and listen for air leaks.

2. Ensure that the alternator lights on the remote box remain OFF when engine is running.

3. Run Exterior Lights and Indicator Lamps test. Inspect all exterior lights and ensure that they are functional.
Refer to "Pre-Trip Lights Test" on page 77 in this manual for more details.

The Exterior Lights and Indicator Lamps test is useful to check proper operation of the multiplex
outputs and the exterior lights illumination. It doesn’t test the functionality of the commands related to
the exterior lighting. For a complete testing, the directional signal operation, the headlights operation
and the brake lights operation have to be performed. Once these commands are tested, activate the
test mode to check the exterior lighting.

4. Check the wheelchair lift (if equipped) operation daily.

5. Position the inside and outside mirrors. Adjust the driver’s seat for comfort and fasten seatbelt.

6. Check that the steering wheel tilt / telescope lever functions correctly.

7. Check steering wheel operation with engine running. Steering should operate smoothly from left-hand to
right-hand max turn stops without binding or erratic movement.

8. Check for proper operation of defroster, heater, windshield wipers and washers, and horn.

9. Ensure that the dual air pressure gauge shows at least 100 psi pressure in both the primary and secondary
circuits.

10. Position Fast Idle switch to the ON position to build up air pressure, and monitor air gauges.

11. Test service brake and parking brake and ensure that they are functional.

Mirrors

If the operator does not turn the main Battery Disconnect switch to the OFF position, the Electrical System will go
into “Sleep Mode” thirty (30) minutes after turning the Ignition switch OFF. The operator can “wake” the Electrical
System by activating the Entrance Door switch, the Hazard Lights switch, or by turning on the Master Power /
Ignition switch.

Driver’s Seat
Driver’s Seat Controls

DO NOT attempt adjustment of the driver’s seat while the coach is in motion. The seat could
move suddenly and unexpectedly, causing the driver to lose control of the vehicle.

After making a seat adjustment, ALWAYS test to ensure that the adjusters have latched.
Improperly latched seat adjusting mechanisms can impair driving capabilities and create an
unsafe operating condition. Report any seat mechanism locking problem immediately to
service personnel.

The basic driver's seat can be manually adjusted for height, fore and aft positioning, setback tilt and seat cushion
pitch. After adjusting a manually operated seat, test by pushing forward and rearward on the seat. Make sure
seat does not move, and that the adjuster mechanisms have latched.

Seat Height Adjustment

The height adjusting knob is located on the left-hand front edge of the seat cushion. Rotate the knobs to adjust
the height of the seat.

Headrest Support

Adjust the headrest height by pulling up or pushing down on the top of the headrest. Position the headrest to the
desired height. Make certain the headrest locks into place after adjusting.

Final Adjustment Checks

After making any of the manually operated seat adjustments, test the seat by pushing forward and rearward.
Make sure it will not move and that the seat adjusters have securely latched. Any movement of the seat indicates
that at least one indexing pin has not engaged. An improperly latched seat mechanism could impair driver
capabilities. Report any seat adjustment or locking mechanism problems to service personnel immediately.

Seat Belts

Not wearing a seat belt properly increases the chance of serious injury or death in a collision.

Seat belts are the single most effective safety device because they keep you connected to the coach so that you
can take advantage of many built-in safety features. They also help keep you from being ejected outside of your
seat. In addition, seat belts help protect you in almost every type of collision, including frontal impacts, side
impacts, rear impacts, and rollovers.

If the seat belt is extended too quickly, it will lock in place. If this happens, slightly retract the seat
belt, then extend it slowly.

Seat Belt Inspection

Not checking or maintaining seat belts can result in serious injury or death if the seat belts do
not work properly when needed. Check the seat belts regularly and have any problem
corrected as soon as possible.

Inspect passenger and driver seat belts, buckles, latch plates, retractors, tethers, guide loops, and mounting
hardware for visible webbing wear or damage, including frays, cuts, burns, discolorations, abrasions, or any
other physical damage. The retractor should operate smoothly, and the belt buckles should latch easily. Also
check for loose or damaged parts that could keep the Restraint System from operating properly. Keep sharp
edges and sharp objects away from the belts and other parts of the Restraint System. Any belts that are
questionable, do not meet the above criteria, or were involved in a collision should be replaced regardless of
mileage.

Seat Belt Cleaning

Belts should be kept clean and dry. Clean seat belts with mild soap and lukewarm water only, and avoid
bleaching or dying belts as this may weaken them.

After cleaning, make sure seat belt is completely dry before allowing it to retract.

Rev. A - November 2024 74 D45 CRT Operator - 6500629

 DRAFT PRE-SERVICE PREPARATIONS

Proper Use of Seat Belts

DO NOT put any accessories on the seat belts. Devices intended to improve comfort or reposi-
tion the shoulder part of a seat belt can reduce the protective capability and increase the
chance of serious injury in a collision.

All occupants should sit upright, well back in the seat, and remain in that position for the duration of the trip.
Slouching and leaning reduce the effectiveness of the belt.

Never place the shoulder part of a lap/shoulder belt under your arm or behind your back. This could cause very
serious injuries in a collision.

Most States and all Canadian provinces and territories require driver’s to wear seat belts. The Seat
Belt indicator will illuminate if the driver does not fasten their seat belt. Following State and
Provincial regulations for driver’s and passenger’s seat belts, MCI strongly recommends wearing
them at all times to enhance your safety.

Fastening a Seat Belt

Make sure that the belt is not twisted or not caught on anything.

After adjusting a seat to the proper position and while sitting upright and well back in the seat:

1. Pull the seat belt out slowly.

2. Insert the latch plate into the buckle, then tug on the belt to make sure the belt is secure.

Improperly positioning the seat belts can cause serious injury or death in a collision. Make
sure all seat belts are properly positioned when in operation.
3. Position the lap part of the belt as low as possible across your hips, then pull up on the should part of the belt
so the lap part fits snugly. See "Figure 63: Seat Belt Adjustment" on page 76.

4. Adjust to a snug fit by pulling the belt firmly across your lap toward the lap belt retractor so it can take up the
slack.

5. If necessary, pull up on the belt again to remove any slack, then check that the belt rests across the center of
your chest and over your shoulder.

DO NOT let the belt twist while it is rewinding into the retractor. The bulk of the twisted belt
may cause the retractor to jam so it will not rewind further. At the same time the retractor may
keep the belt from being pulled out.

6. To unfasten the belt, push in the button in the center of the buckle. The retractor is designed to rewind the
belt automatically when the buckle is unlatched.

PRE-SERVICE PREPARATIONS
DRAFT

No one should sit in a seat with an inoperative seat belt or one that does not appear to be
working correctly. Using a seat belt that is not working properly may not protect the occupant
in a collision. Have a technician to check any questionable belts as soon as possible.

If a belt should get jammed, you may be able to release it by working the belt in and out until the belt rewinds far
enough to unlock. If the belt remains jammed the seat belt system may not operate correctly and should be
replaced.

Seat Belts for Children

Follow State and Provincial Regulations for securing children passenger’s with a seatbelt.

Seat Belts for Pregnant Women

If you are pregnant, the best way to protect yourself and your unborn child when driving or riding in a coach is to
always wear a seat belt and keep the lap part of the belt as low as possible across the hips. A doctor should also
be consulted for any specific recommendations.

 DRAFT COACH OPERATION

6 - COACH OPERATION
Engine

Before you proceed with coach operation, be sure there is ample distance ahead of and
behind the coach in case of sudden unexpected movement during engine starting. Before
starting, make sure the Fast Idle switch is off and the parking brake is applied. DO NOT
accelerate the engine during initial start-up.

Starting the Engine

Before starting the engine, ensure that FAST IDLE feature is OFF, transmission is in Neutral
[N], and the parking is applied.

DO NOT start the engine when the engine warning lights stay on or do not come on momentar-
ily after turning on the ignition. Operating the engine under these circumstances may cause
engine damage.

DO NOT engage the starter for longer than 15 seconds at a time. Allow starter motor to cool
before a second attempt. Continuous use of the starter without allowing a cooling period may
damage the starter motor.

Special precautions are necessary with turbocharged engines to avoid possible turbine dam-
age. After starting, run the engine at normal idle for two minutes to allow lubricating oil to
reach the turbocharger. Then run the engine at fast idle. Let oil pressure reach normal operat-
ing range before driving.

1. Ensure that the Main Battery Disconnect switch is in the ON position.

2. Ensure that the parking brake control knob is pulled OUT in the parking brakes APPLIED position.

3. Press the Master Power / Ignition switch to the ON (upper) position to enable all of the multiplex modules and
turn on the coach’s Electrical System.

4. Ensure the Transmission Shift Pad indicator is in Neutral [N]

5. Wait for the Check Engine and Stop Eng Indicator lights to extinguish.

6. Start the engine using the Engine Start switch on the left-hand switch panel.

7. Check all gauges and indicator lamps for proper function.

8. Position the Fast Idle switch to ON in order to build up air pressure.

9. Look and listen for any indications of system or equipment malfunction. Report any sign of trouble to service
personnel before operating the coach further.

After ignition is turned ON, wait for 17 seconds before starting the engine is recommended.

Engine Warm-Up
After the initial starting and low idle engine operation, it is necessary to activate the fast idle for three minutes to
bring engine up to temperature, or to quickly fill the Air System. Parking brakes should be kept applied during

D45 CRT Operator - 6500629 79 Rev. A - November 2024

COACH OPERATION
DRAFT
initial warm-up, and must be on before the fast idle will operate. Observe gauges and indicator lamps frequently
during warm-up and subsequent operation. If abnormal conditions develop, stop engine immediately and
determine cause.

Fast idle function is interlocked to the parking brake.

Stopping the Engine

Shutting down a turbo-charged engine directly from a high RPM condition may cause damage
to the turbocharger. Idling at a low RPM before shutting down the engine assures that the tur-
bine speed has dropped.

1. Bring coach to a complete stop.

2. Place transmission in Neutral [N] and apply the parking brake.

3. Idle engine at low RPM for 30 seconds, then turn the ignition OFF.

Engine Electronic System - Warning

Each engine installation is equipped with a Notification System to warn the operator of an abnormal oil/coolant
level and/or temperature condition. Such conditions are notified by indicator lights and buzzer from the
instrument panel. Coaches have an automatic system to power-down and/or shutdown engine operation if any
abnormal conditions arise.

The automatic power-down or shutdown can be temporarily over-ridden to move the coach to a safe location.

If the engine has begun the 30-second power-down sequence, the following procedure can be used to keep the
coach in motion:

1. Activate the Engine Shutdown Override switch located on the left-hand switch panel.

2. Continue coach travel until a safe location is found. Operate engine at lowest RPM possible while moving the
coach.

If the engine has automatically shut down, the following procedure must be used to restart and move the coach:

1. Momentarily turn the Ignition switch to the OFF position and back to ON again.

2. Press the Engine Shutdown Override switch and attempt to restart engine with the Engine Start switch.

3. Move the coach to a safe location. Operate the engine at lowest RPM possible while moving the coach.

Engine Oil Gauge

Normal pressure readings in operation are 50 to 70 psi (345 to 483 kPa) at 1,800 RPM. If the oil pressure drops
below a safe level during operation, the CHECK ENGINE or STOP ENGINE Indicator lights will illuminate. This
condition should cause the coach engine to automatically shutdown.

Lubricating Oil Specification

Cummins Diesel X12 Engines have an oil capacity of 9.0 U.S. gallons (34 L).

Diesel engines require heavy-duty lubricating oils. The only lubricating oil recommended for X12 diesel engines
is CES 20086 and Viscosity Grade SAE10W-30, API Classification CK-4.

Rev. A - November 2024 80 D45 CRT Operator - 6500629

 DRAFT COACH OPERATION

Synthetic oils may be used in engines, provided they are API licensed and meet the performance and chemical
requirements of non-synthetic oils in the API Category III and Viscosity Grade SAE 10W-30. The use of synthetic
oils does not extend the oil drain interval recommended.

Engine Brake

The engine braking feature is meant to supplement, not replace the service brakes nor
intended to bring the vehicle to a stop. Engine brake is designed to reduce the speed of your
vehicle under a certain conditions.

Before activating the engine brake, make sure that the coach is maintaining traction and
stability by using the natural retarding of the engine alone. If the retarding of the engine alone
causes any loss of traction, DO NOT attempt to use the engine brake until road conditions
improve.

This coach is equipped with auxiliary engine brakes that use the engine to aid in slowing and controlling the
coach. When activated, the engine brake alters the operation of the engine’s exhaust valves so that the engine
works as a power-absorbing air compressor.

Operation

There are two (2) levels of engine brake available to choose from and the control switch is located on the left-
hand switch panel. See "Figure 65: Engine Brake Switch & Indicator" on page 82. To enable engine brake, press
the switch up for HI level and down for LOW. HI level will provide more aggressive brake power than LOW. An
indicator (AUX) on the dash illuminates when the system is active.

The operation of the engine brake is fully automatic once turned on. When the driver releases the throttle, the
engine brake will automatically apply. Once pressure is being applied to the throttle, the engine brake is
deactivated. To turn off the engine brake system, put the switch to the middle position and the indicator on the
instrument panel will extinguish.

When cruise control is active, and engine braking has not been turned off by the rocker switch, if the
coach starts to exceed the cruise set speed by a certain amount (eg. going downhill), engine brakes
will automatically progressively engage to reduce the amount of overspeed that will occur. When the
vehicle speed falls back to set speed, engine braking will stop, and normal cruise operation will
continue. No driver interaction is required.

Engine Oil Fill & Dipstick

Cummins X12 engines use CK-4 10W-30 recommended engine oil. Failure to use CK-4 engine
oil will reduce component life.

The engine oil fill and dipstick is accessible through the rear engine access doors. See "Figure 66: Engine Oil Fill
& Dipstick Location" on page 82.

The MCI warranty applicable to X12 diesel engines provides in part that the provisions of such
warranty shall not apply to any engine unit that has been subjected to misuse, negligence, or
accident. Malfunctions attributable to neglect or failure to follow manufacturer’s fuel or lubricating oil
recommendations will not be covered by MCI or Cummins.

 DRAFT COACH OPERATION

Engine Coolant Temperature (Overheat)

The engine coolant temperature range varies between the different engines. If possible, avoid going to full
throttle until engine temperature reaches 140°F (60°C). The engine will come up to normal operating temperature
shortly after driving. A coolant temperature gauge displaying the operating temperature is located on the MDF
LCD screen.

If the engine becomes overheated during operation, the Check Engine or Stop Engine indicator lights will
illuminate. This condition should also cause the coach engine to derate (check engine) or automatically shutdown
(stop engine). If overheating occurs, check water level of engine Cooling System. Refer to "Cooling System" on
page 83 in this manual for other possible causes.

Immersion Heater (Optional)

This coach may be equipped with an engine block immersion heater for use as an aid in cold weather conditions.
The power cord plugs into a typical 120VAC outlet. When plugged in, the element radiates heat throughout the
coolant, engine lubricating oil, and engine block.

Cooling System
The engine Cooling System maintains proper operating temperature of the coach engine and also provides a
supply of heated water for the Heating System. The Cooling System is filled through the surge tank filler neck.

Coolant Level Check

NEVER open the fill cap on the surge tank when engine is hot. Coolant is very hot and under
high pressure.

Coolant level can be checked at the surge tank through the sight glass. See "Figure 67: Surge Tank / Sight
Glass" on page 83. The surge tank is located in the top left corner of the engine compartment.

COACH OPERATION
DRAFT
Transmission
The B500 series GEN VI is an electronically-controlled, hydraulic actuated, power shifting, six-speed torque
converter automatic transmission with lockup torque converter. This transmission controls all aspects of the shift
function once placed into the desired drive range. Shift range selections are made with the touch-pad module
located on the lower left-hand console. See "Figure 68: Shift Selector" on page 86.

A two-character digital display is located at the top of the automatic transmission shift selector. The left character
of the display, SELECT, designates Neutral [N], Reverse [R], or the highest gear available of the selected forward
range. The right character of the display, MONITOR, designates the actual gear which is being commanded and
attained by the Transmission Control Module (TCM).

Two-character diagnostic codes can be accessed using the touch pad on the shift selector.

The MODE button can be utilized to invoke a special function that has been programmed into the TCM. A small
red light is illuminated on the MODE button when the function is activated.

The gear selector should ALWAYS be in the NEUTRAL [N] position when the coach is parked.

Shift Inhibit Logic

This system prevents the transmission from selecting a gear unless there is a full brake application (60 psi), the
Low Entry mode is deactivated, and the kneeling feature is deactivated.

Shift Selection
The following is a brief description of the symbols used for gear range selection on the automatic transmission
shift selector:
• [R] - Reverse
• [N] - Neutral
• [D] - Drive: the highest forward gear will appear on the SELECT display. The transmission will shift to the
starting gear, on the MONITOR display.

There is no PARK position on the shift selector.

ALWAYS apply the parking brake to hold the coach while unattended and place the shift selec-
tor in the NEUTRAL [N] position. Refer to "Releasing Service or Parking Brakes" on page 90 in this
manual for the proper parking brake application and release procedure.

When shifting from Neutral [N] to Drive [D] or Reverse [R] range, the engine should be at nor-
mal idle speed. When the coach is parked, the transmission should ALWAYS be in the Neutral
[N] position.

During normal operation with Drive [D] selected, the SELECT display shows the highest attainable forward range.
The MONITOR display shows the gear which has been commanded by the TCM (actual gear in which the
transmission is currently operating).

The UPSHIFT and DOWNSHIFT arrow buttons ( Δ and ∇) are used to select higher, (if not in Drive [D]), or lower,
(if not in 1), forward range. One press of the pushbutton changes the range selected by one range. If the
pushbutton is held down continuously, the selected range will continue to change up or down until the button is
released or until the highest or lowest possible range of gears is selected.

Rev. A - November 2024 84 D45 CRT Operator - 6500629

 DRAFT COACH OPERATION

Even though a lower range is selected, the transmission may not down-shift until coach speed is reduced, thus
preventing engine over speed in the lower range.

The UPSHIFT and DOWNSHIFT arrow buttons are not functional in Reverse [R] or in Neutral [N].

Indicator Warning Light

The Electronic Control System is programmed to alert the driver that a problem has been detected by illuminating
the CHECK TRANS in the display cluster.

Illumination of the CHECK TRANS at any time after engine start (system check) indicates that a problem has
been detected. When a problem condition has been detected, the TCM / ECU will:
• Illuminate the CHECK TRANS indicator lamp
• Flash the display on the pushbutton shift selector
• Restrict shifting
• Register a diagnostic code

DO NOT attempt shutdown of engine or shift transmission until coach is safely parked. If shut-
down and restart is attempted, the transmission will shift into Neutral [N], which will discon-
tinue the Limp Home feature and leave the coach stranded until the fault is cleared.

Generally, while the CHECK TRANS lamp is illuminated, the up-shifts and down-shifts will be restricted and
direction changes will not occur. The pushbutton selector should not respond to any operator shift requests while
the CHECK TRANS indicator lamp is on.

When the CHECK TRANS lamp is illuminated, the transmission will operate in the Limp Home mode with reduced
capabilities. The Limp Home feature will lockup the transmission in the current gear to enable continued coach
operation for a short time until it can be moved safely out of traffic. Advise service personnel immediately to
minimize the potential for damage to the transmission.

Diagnostic Code Retrieval

Diagnostic codes, displayed as two digit numbers, indicate a transmission malfunction. Diagnostic codes can be
accessed through the pushbutton shift selector. These codes are logged in the TCM / ECU with the most severe
or recent code listed first.

A maximum of five codes, identified as d1 to d5, can be listed at one time. As codes are added, the oldest non-

The coach must be parked on a level surface with the transmission in Neutral [N] and the parking brake applied.
The fluid level check may be delayed until the following conditions are met:
• The fluid temperature is above 140°F (60°C) and below 220°F (104°C).
• The transmission is in Neutral [N].
• The engine is at idle.
• The transmission output shaft has stopped.
• The coach has been stationary for approximately two minutes, allowing fluid to settle.

 DRAFT COACH OPERATION

The pushbutton shift selector will indicate a delayed fluid level check by a flashing display under SELECT and a
digital countdown from 8 to 1 under MONITOR. To access fluid level diagnostic information, simultaneously press
the Δ and ∇ buttons to access the Fluid Level Display Mode. A correct fluid level is reported when an OL is
displayed (OL indicates the Oil Level Check Mode), followed by OK. The OK display indicates that the fluid level
is within the correct fluid level zone.

The dipstick check may not agree exactly with sensor checks due to the oil level sensor
compensating for fluid temperature.

Low fluid level is reported when an OL is displayed by LO and a number. LO indicates a low fluid level, and the
number indicates quarts of fluid the transmission requires. OL LO 02 indicates that two additional quarts of fluid
should bring the level to the acceptable zone. Confirm an electronically obtained low fluid condition by making a
manual fluid level check. High fluid level is reported when an OL is displayed, followed by HI and a number. HI
indicates a high fluid level and the number indicates quarts overfilled. OL HI 01 indicates one quart past the full
level.

Invalid display conditions are reported when an OL is displayed, followed by a -- and a number. The displayed
number is a code, and would indicate improper condition for electronic check or a system malfunction. OL--70
would indicate that the oil sump temperature is too low.

The Invalid Display is activated when conditions do not allow the fluid level to be checked. Review

Brakes

Stop lights on the rear of the coach automatically illuminate when the brake pedal is
depressed.

This coach is equipped with air-operated service brakes which are applied using the foot pedal to the left of the
accelerator pedal. The amount of pressure applied to the pedal determines the extent and force of the brake
application. See "Figure 70: Service Brake Pedal Location" on page 89.

Air system pressure must be at least 100 psi (689 kPa) before brakes can develop their full effectiveness.
Observe the air pressures indicated on the dual air gauge at frequent intervals during coach operation.

Fanning or pumping the brake pedal is not recommended. This practice reduces the effectiveness of
the Brake System and interferes with the ABS System. It also wastes air and causes unnecessary
wear on brake parts.

mo00000077a.svg

Figure 70: Service Brake Pedal Location

Anti-Lock Brake System (ABS)

DO NOT pump the brake pedal, this defeats the purpose of the ABS.

The Anti-Lock Brake System (ABS) minimizes the potential of brake lock-up in low traction road conditions or in
panic stop braking situations. The coach retains a greater degree of stability and ability to steer properly.

During braking, the ABS System automatically senses any impending wheel lock-up due to loss of traction. The
system monitors deceleration rates during braking and automatically pulses brake application pressures at each
wheel.

An ABS indicator light on the Multi Function Display cluster tells the condition of the ABS. At coach starting, the
indicator first flashes and goes out. If the indicator illuminates when the coach is moving at road speed (above 5
to 7 MPH), the ABS is malfunctioning and service is required. An ABS malfunction automatically reverts the
Brake System to standard non-ABS operation.

High Traction Road Conditions

The ABS is not activated during normal brake applications on high traction, dry road surfaces. During braking,
apply a firm, positive brake pedal pressure.

Low Traction Road Conditions

Do not pump or fan the brakes in low traction road conditions. Apply firm, positive pedal pressure for the ABS to
be most effective. The sensors and modulator valves cause the brakes to pulse and modulate at a very rapid
rate, sensing any wheel which is near lock-up because of less traction and which wheels have enough traction.

COACH OPERATION
DRAFT
Panic Stop Braking Conditions
Do not pump or fan the brakes in panic stop braking conditions. Apply firm, continuous, heavy pedal pressure.
The brakes pulse and modulate at a very rapid rate, sensing which wheels are near lock-up because of less
traction and which wheels have enough traction. Brake pressure automatically adjusts at each wheel. In this way,
traction is maintained between the road surface and tires, increasing the potential for stable, non-skid stops
maintaining steering control.

Releasing Service or Parking Brakes

Use the following release procedure to free service or parking brakes. DO NOT attempt to
brake the coach free with engine power if the brakes fail to release.

In the event of a normal service brake fails to release, reduce air pressure to below 75 ± 5 psi (517 ± 34.5 kPa)
by pumping the brake pedal. Operate the engine until dual air gauge reads above 100 psi. Make a normal service
brake application and then release it, or make a normal parking brake application, release it, and then make a
service brake application and release it. One of these procedures should free the brakes.

Parking & Emergency Brakes

The coach is equipped with an air-operated parking brake control valve to release the spring applied parking
brakes for parking the vehicle and for emergency braking function. The parking brake control valve is located to
the left of the driver under the Ignition switch panel. A guard over the valve prevents accidental release of the
parking brakes. See "Figure 71: Parking Brake Control Valve Location" on page 91.

DO NOT apply the parking brakes until the coach has come to a complete stop.

Operation of the system is as follows:

1. Stop the coach by firmly applying the service brake pedal. Pull up on the parking brake valve knob to set the
parking brakes. Brakes will remain applied and locked, even if the coach air pressure is lost. Always apply
parking brakes by pulling up on the parking brake valve knob before leaving the coach.

2. Put the transmission in Neutral [N] by firmly pushing on the [N] pushbutton on the transmission touch pad.

Parking Brake Release

Push in the parking brake control valve, followed by a full service brake application. Parking brake release should
allow normal service brake operation.

The parking brake is required to be manually set whenever the driver leaves the driver’s seat.

The parking brake is interlocked with, and affects the operation of several other coach components. The
relationship between these components and the parking brake interlock are as follows:
• Kneeling Feature - Applying the parking brake energizes the kneeling relay when the Kneel switch is activated.
Releasing the parking brake de-energizes the kneeling relay and the coach returns to ride height if in the
Kneeling Mode.
• Wheelchair Lift (if equipped) - The parking brake is interlocked by the Wheelchair Key switch. Parking brake
must be set for wheelchair key to enable the Wheelchair System.

At coach speeds less than 2 MPH, the wheelchair parking brake interlock is set.

Emergency Parking Brake Release

Fully apply the service brakes to ensure complete release of the parking brake. Refer to "Releas-
ing Service or Parking Brakes" on page 90 in this manual for procedure if the parking brake fails to

The wheelchair lift and wheelchair lift upper door (if equipped) must be closed before the park-
ing brake will release.

The emergency parking brake release valve is a manually operated valve. It is used for emergency parking brake
release. The valve is spring loaded and remains in the UPPER position unless constant manual downward force
is applied to release the parking brakes. See "Figure 72: Emergency Parking Brake Location" on page 92.

Tag Axle Steering & Lock Function

The tag axle is designed to caster steer freely only at low forward speed. This will result in a shorter
turning radius and give you more maneuverability in tight spaces. If forward speed reaches above 15
mph, the tag axle will lock-up in a straight ahead position. If speed falls below 10 mph, the tag axle
will unlock and caster steer freely again. The locking and unlocking is controlled by an electronic
Multiplex System with the programmed speed and logic.

You can override the tag lock condition only at forward speed below 10 mph. This can be done via activating the
Tag Lock switch on the LH console. Pressing on the LOCK position will override the default condition and lock-up
the tag axle. Pressing on the AUTO position will put the system back into default mode.

ATC/ABS (Mud/Snow & ABS Diagnostic) Switch

The Automatic Traction Control (ATC) System will intervene automatically limiting engine torque and
applying braking pressure to a spinning drive wheel transferring engine power to the other drive
wheel that has better traction. This feature is active only at speeds below 25 mph.

If drive wheels begin to lose traction during acceleration, ATC will engage automatically to assist the driver in
accelerating the vehicle. The ATC Indicator light will flash rapidly to let you know whenever ATC is actively
functioning.

Enabling the MUD SNOW mode allows greater engine power and more wheel spin during ATC operation. It is
recommended to turn on this feature when operating on soft road surfaces. The ATC Indicator light will flash
slowly to remind you that this function has been selected, and will flash rapidly whenever the ATC System is
actually operating in the MUD SNOW mode. Always remember to turn the MUD SNOW feature OFF when driving
on a firm road surface. A new ignition cycle, or a second depression of the Mud Snow switch will turn this function
OFF. Press the ABS DIAG to retrieve ABS blink codes from the ABS indicator. Refer to OEM manual for
diagnostic blink codes.

 DRAFT COACH OPERATION

Electronic Stability Control (ESC)

This coach is equipped with a Stability Control System (ESC) that features ESC combined with Roll Stability
Control (RSC). ESC is a computerized technology that improves the safety of a coach’s handling by detecting
and potentially preventing skids by automatically applying brakes to help steer the coach where the driver wants
to go.

During an ESC System intervention, the coach automatically decelerates. The ESC System can
slow the coach with or without you applying the brake pedal, and even when you are applying
the throttle. Even with the ESC System equipped, the driver remains responsible for ensuring
coach stability during operation.

In the case where a coach equipped with the ESC System pulls a trailer, the latter must be
equipped with ABS.

The Electronic Stability Control is automatic in that these systems become active when the Electronic Control
Unit (ECU) senses conditions that could produce imminent roll or directional instabilities. Rapid lane changes or
cornering at excessive speed on dry or slippery surfaces can create the potential for spin-out or drift out, often
before the operator is aware. The ESC System uses a lateral accelerometer, a steer angle sensor in the steering
column and a yaw rate sensor to enhance the operator’s control in these conditions.

Wingman® Fusion® System (Optional)

The Wingman® Fusion™ System is an integrated combination of these features:
• Adaptive Cruise Control with Braking
• Collision Mitigation Technology (Enhanced)
• Lane Departure Warning (LDW)
• Traffic Signal Recognition (TSR)

The Wingman® Fusion™ System combines radar, camera, and the coach’s Brake System to deliver adaptive
cruise control with braking, enhanced collision mitigation, lane departure warning, and over speed alerts. Visual
and / or audible alerts are integrated into the coach’s dash display (MFD).

Main Wingman® Fusion™ System Components

Wingman® Fusion™ System safety technologies complement safe driving practices. No

commercial coach safety technology replaces a skilled, alert driver exercising safe driving
techniques and proactive, comprehensive driver training. Responsibility for the safe
operation of the coach remains with the driver at all times. Improper use of the Wingman®
Fusion™ System can result in a collision causing property damage, serious injuries, or death.

The Radar System only senses metallic objects. Non-metallic or limited metallic objects such
as people, animals, RVs, motorcycles, horse drawn buggies, logging vehicle’s, or cross-traffic
will not trigger the system.

Under no circumstances must the radar be removed or repositioned from the original
production line installation. The assembly should ALWAYS be mounted in the OEM location.
The radar cover cannot be painted or covered by license plate, decal, or graphic film.

D45 CRT Operator - 6500629 97 Rev. A - November 2024

COACH OPERATION
DRAFT
The main components are the ESP EC-80 Controller, the FLR21 Radar, and the AutoVue FLC20 Camera. The
system uses these components for Adaptive Cruise-Control with Braking (ACB), Collision Mitigation Technology
(enhanced), Lane Departure Warning (LDW) and Traffic Sign Recognition (TSR).

Vehicle equipment, including bumpers, deer guards, etc, must not infringe upon the zone used
by the radar sensor to emit and receive radar wave. Failure to comply with this requirement
will impair the function of the radar. Only vehicle OEM-approved covers and/or cover panels
may be installed in front of the radar.

The Wingman® Fusion™ System also assists by giving audible and visual alerts, whether or not cruise control is
on.

Volume Control Audible Alerts

Audible alerts are meant to warn the operators of a situation. Volume levels must be kept at a
moderate decibel so it can be heard while the coach is in operation.

The volume control for Wingman Fusion can be adjusted either in drive or park mode, only collision mitigation
and braking warning alerts are not adjustable, they are fixed at a max volume. See "Figure 77: Volume Controls"

Adaptive Cruise Control with Braking (ACB)

The Adaptive Cruise Control with Braking (ACB) features should not be used in certain operat-
ing conditions including the following:

• Inclement Weather / Low Visibility Situations

• Dense Traffic
• Sharp Curves and / or Winding Roads
• Entrance or Exit Ramps
• Downhill Grades
• Construction Zones
• Off-Road
• Smaller Forward Vehicle’s

The Adaptive Cruise Control with Braking (ACB) feature is an additional upgrade of ordinary cruise control. ACB
is automatically activated when cruise control is set. It helps maintain a constant vehicle speed and set following
interval behind a vehicle detected ahead of yours, without you having to keep your foot on the brake pedal or
accelerator.

Using the radar sensor mounted to the front of the coach, with a range of approximately 500 feet, the system
reacts to detected forward vehicle’s in the same lane, traveling in the same direction. See "Figure 78: System
Intervention Zone" on page 101.

If the forward vehicle slows down below the vehicle’s cruise control set speed, the system will de-throttle the
engine, progressively apply the engine retarder, and then apply the foundation brakes in an attempt to maintain a
set following interval behind the forward vehicle. If the forward vehicle accelerates away, the ACB System will

Rev. A - November 2024 100 D45 CRT Operator - 6500629

automatically accelerate your coach to the original cruise control set speed, and again maintain a set following
interval behind the forward vehicle.

Since the Wingman® Fusion™ System operates along with normal cruise control, all the typical features built into
cruise control work as usual. For example, SET/COAST, RESUME/COAST, SET/ACCEL, and RESUME/ACCEL
are fully supported by the Wingman® Fusion™ System.

DO NOT use cruise control when driving speed must constantly be adjusted, such as in heavy traffic,
or on icy, snow-covered, slippery, or gravel roads.

Braking Overuse

The Wingman® Fusion™ System provides a warning when the system is intervening and using
the foundation brakes excessively. Overuse of the foundation brakes can lead to the brakes
overheating and a potential loss of braking performance caused by brake fade. Using cruise
control on downhill grades will cause this alert to be activated.

Cruise control should NOT be used on downhill grades. Approach grades as you would nor-
mally, with the appropriate gear selected and at a safe speed.

To guard against foundation brake overuse by the adaptive cruise control with braking feature of the Wingman®
Fusion™ System, the frequency of foundation brake interventions is monitored. If the system detects a situation
where the brakes are being applied too frequently by the system in a given time period, the Brake Overuse Alert
will activate. This is designed to help prevent overheating of the brakes, which may lead to brake fade and
reduced coach braking capability. In this situation, the Brake Overuse will alert the operator.
• The intervention cancels cruise control.
• After a Brake Overuse Alert, for a period of time (typically 20 minutes), the Wingman® Fusion™ System will not
use the foundation brakes when intervening. The system will be limited to de-throttling the engine and applying
the engine retarder.

In all cases, the driver still has the ability to apply the foundation brakes if necessary. The driver
should take care since overheated brakes may reduce the coach’s braking capability.

• The time period for this mode is measured from the time the Brake Overuse Alert was activated and lasts
approximately 20 minutes.
• The system will set a Diagnostic Trouble Code (DTC) and braking will be disabled until the next ignition cycle.

The operator will continue to receive all three alerts (Following Distance, Impact and Stationary
Object).

Collision Mitigation Technology (CMT)

The Collision Mitigation Technology (CMT) is designed to be ready to alert the driver of detectable objects in front
of your coach (whether or not cruise control is set) and react to the presence of stationary/moving vehicle’s in the
lane ahead. Collision mitigation interventions provide the driver with an alert before an intervention occurs.

These alerts will change as the interval between the two vehicle’s (or object) decreases alerting the operator of
the impending hazard. As the interval closes, the system will automatically intervene and slow the coach in three
ways in the following order, reduce throttle, engage retarder, and apply foundation brakes.

NOTE:
The driver must immediately act to potentially avoid, or lessen the severity of a collision.

If a collision is likely to occur, and the Collision Mitigation feature activates the foundation brakes, the tone of the
alert will typically change and display a driver intervention warning. The driver must immediately act to potentially
avoid, or lessen the severity of a collision.

Stationary Vehicle Braking (SVB)

The Wingman® Fusion™ System is ready to alert the operator whenever the coach is moving
above 15 mph (24 kph). The driver should be especially careful when approaching certain
types of vehicle’s or objects. The Wingman® Fusion™ System radar may not be able to detect
vehicle’s with limited metal surfaces such as recreational vehicle’s, horse-drawn buggies,
motorcycles, logging trailers, etc).

NOTE:
Entering a curve may reduce the alert time.

Any audible and/or visual alert by the system means that your coach is too close to the
vehicle ahead and the driver must immediately act to potentially avoid, or lessen the severity
of a collision.

The driver should inspect the radar and camera mounting brackets regularly and keep the
windshield and bumper locations clear of any mud, snow, ice build-up, or other obstructions.
The installation of aftermarket deer guards, bumper guards, snow plows or similar potential
obstructions is not recommended, and could impair the operation of the radar.

The system uses both radar and camera data to confirm the vehicle ahead. With an activation speed above 15
mph, here is how this dynamic feature works: When the large, stationary, metallic object in a vehicle’s lane of
travel is definitively identified as a licensed motorized vehicle, the driver is notified up to 3.5 seconds before
impact. If the driver does not take action to address the potential impact that caused the alert, Wingman®
Fusion™ can automatically engage the brakes to assist the driver in reducing the severity of or potentially
avoiding a collision with the stationary vehicle.

If the system cannot definitively identify the stationary object as a licensed motorized vehicle, the driver will get
up to 3.0 seconds of alert to address the situation ahead; no automatic braking will be applied. SVB is most
useful when approaching a line of stopped traffic or a stalled vehicle that is not immediately recognized by the
driver. Without the automatic alert and braking, it may be too late to avoid impact. As always, responsibility for
the safe operation of the coach remains with the driver at all times.

Lane Departure Warning (LDW)

The Wingman® Fusion™ System has the ability to warn the driver if the coach is not tracking
in the intended roadway path. In most coach applications the LDW System is enabled above 37
mph. The driver should immediately correct the coach tracking and maintain the correct
position in the lane.

The Wingman® Fusion™ System uses the Forward Looking Camera to monitor the visible lane markings on the
road and when an unexpected lane change takes place (without an activated turn signal), visual and audible
warnings alert the driver to make a correction. Tired, distracted, or inattentive drivers are alerted and can take
remedial actions. The LDW System is enabled above 37 mph / 60 kph.

The LDW may not detect all lane markings or lane departures. Accuracy will vary based on weather,
speed, and lane marker condition. When it fails to detect lanes, the LDW System will temporarily be
inactive. It is ALWAYS your responsibility to safely operate the coach and avoid collisions.

Lane Departure Disabled

Due to the inherent limitations of image recognition technology, camera-based safety

technology, on rare occasions may not be able to detect or may misinterpret lane markings. At
these times, alerts may not occur, or erroneous alerts may occur.

Whenever re-installing or replacing a camera (for example, after a windshield is replaced), the
recommended position for the coach must be used. Failure to install the camera in the correct
position can result in system Diagnostic Trouble Codes being set, and system performance
degradation.

The operator may disable LDW momentary by turning on the LDW DISABLE switch located on the left-hand
console. This is typically used when driving through construction zones where false alerts may exist continuously.
Each time the switch is activated, LDW will be inactive for 15 minutes. The system will automatically enable itself
after 15 minutes, or pressing the switch again will instantly enable LDW.

MAINTENANCE - In normal use, the FLC20 Camera needs only a clean, properly maintained
windshield to ensure a clear view of the road ahead. Protect the camera lens whenever the inside of
the windshield is being cleaned.

Traffic Sign Recognition

The Wingman® Fusion™ System has the ability to warn the driver if the coach’s speed
exceeds the posted legal limits. The Over Speed Alert is enabled when the coach is traveling
greater than 5 mph / 8 kph from the posted limit. The driver should immediately reduce speed
to the posted legal limit.

The Wingman® Fusion™ System has the ability to assist the driver by recognizing US and Canadian speed limit
signs. This allows the system to display the current posted speed limit and alert the driver with audible and visual
alerts on the dash display when over speed thresholds are detected.

When the coach exceeds the posted speed limit by 5 mph / 8 kph, an audible alert will sound to alert the driver. If
the coach speed exceeds 10 mph /16 kph over the posted speed limit, an audible alert signals the driver to slow
down and a one-second de-throttle of the engine will occur.

Overuse Alert activated and Traffic Sign Recognition (TSR) will be disabled if: 10 alerts of speed over the limit
(10 mph over) is registered.

Alerts & Warnings

Any audible and/or visual alert by the system means that your coach is too close to the
vehicle ahead and the driver must immediately act to potentially avoid, or lessen the severity
of a collision.

The Wingman® Fusion™ System operates differently compared to other cruise control/forward collision warning
systems. It is important to fully understand the systems features, especially the driver alerts and warnings.

Three important warnings provided by the Wingman® Fusion™ System on MCI Drive Scene display include:
• Following Distance Alert (FDA)
• Collision Mitigation Alert (CMA)
• Stationary Object Alert (SOA)

The operator will be alerted by any of the three warnings, whether or not the cruise control is activated.

Following Distance Alerts (FDA)

The Following Distance Alert is ready to alert the driver whenever the interval time between
your coach and the detected forward vehicle is less than 1.5 seconds and decreasing. Once
the audible alert is given, the driver should increase the distance between his/her coach and
the vehicle ahead until the audible alert stops. The FDA is ready to alert the driver whenever
the coach is moving above 5 mph/8 kph.

Following Distance Alerts (FDA) are generated through the system using coach speed, forward vehicle speed,
distance, and driving scenario. These provide the operator with distance alerts (audible and visual) for the given
situation. If the following distance continues to decrease, the audible alerts will become progressively faster.

These alerts indicate that the interval time between your coach and the detected forward vehi-
cle ahead is less than one and a half (1.5) seconds and decreasing. Once the audible alert is
heard, the operator should increase the distance between their coach and the vehicle ahead
until the audible alert stops.

There are three levels of Following Distance Alerts:

• Level 3 Alert with forward vehicle speed and following distance in seconds with single beep per second.
• Level 2 Alert with forward vehicle speed and following distance in seconds with double beep per second.
• Level 1 Alert with forward vehicle speed and following distance in seconds with continuous beeping.

NOTE:
The value of the following distance in seconds is only an example and not a representation of an actual
operation.

Following Distance Adjustment

There are also three levels of the Following Distance Adjustment:

• Shorter than Normal Distance
• Farthest Distance
• Shortest Following Distance

The Following Distance toward the vehicle ahead of you can be adjusted if the default is not desired. Adjustment
is only achievable if the coach is stationary, transmission is in Neutral [N], and parking brake is applied.

Following Distance Operation

• Press the “Menu” button on the top left of the screen to access the Sub-Menu.
• Press the “Following Distance” button to access the Settings screen.
• To change the Following Distance, press the “+” or “-” button to select FAR, SHORT or SHORTEST. The
default setting is set to NORMAL.
• Press the “Saved” button to apply the changes.

Following Distance in seconds is calculated based on the current speed of the Wingman® Fusion™
System-equipped coach, and the distance, in feet, away from the selected forward vehicle. For
instance, if the selected forward vehicle is 88 feet (27 m) from the bumper of the Wingman® Fusion™
System-equipped truck, and the Wingman® Fusion™ System-equipped truck is traveling 60 mph (97
kph), then the following distance in seconds would be 1.0 seconds because a truck traveling 60 mph
(97 kph) can travel 88 feet (27 m) in one (1) second.

Stationary Object Alert (SOA)

The Wingman® Fusion™ System, Stationary Object Alert (SOA) will give up to a three (3)
second alerts to the driver when approaching a detected, sizable, metallic (radar-reflective),
stationary object in your lane of travel. This alert indicates that a collision with a stationary
object is likely and the driver must immediately act to potentially avoid, or lessen the severity
of a collision.

Stationary Object Alert (SOA) is ready to alert whenever the speed is above 10 mph/16 kph.
The operator should be especially careful when approaching certain types of vehicle’s or
objects. The Wingman® Fusion™ System radar may not be able to detect objects with limited
metal surfaces (such as recreational vehicle’s, horse-drawn buggies, motorcycles, logging
trailers, etc).

Stationary Object Alert (SOA) is an alert given to the driver when the radar detects a sizable, non-moving metallic
object in the coach’s path of travel. To reduce the number of false detections, such as bridges and overhead
signs, a set of filters are put in place so the SOA will not warn on every stationary object.

Figure 91: Stationary Object Detected

Impact Alert

The Impact Alert is the most severe warning issued by the Wingman® Fusion™ System. This
alert indicates that a collision with the detected forward vehicle is likely and the driver must
immediately act to potentially mitigate, or lessen the severity of a collision. The Impact Alert is
ready to alert the driver whenever the coach is moving above 15 mph / 24 kph.

The Impact Alert uses a combination of distance to the vehicle ahead, plus high relative velocity, to decide when
to issue a loud solid tone, as well as a visual indicator to the operator.

When the Impact Alert activates, the operator must immediately act to potentially avoid, or lessen the severity of
a collision. If a collision is likely to occur, and the collision mitigation feature activates the foundation brakes, the
tone of the alert will typically change and the display will show a driver intervention warning. The driver must
immediately act to potentially avoid, or lessen the severity of a collision.

Alarm & Fault Messages

If you are seeing FAULT messages on the display, it means that service is required and the
Wingman® Fusion™ System is not operating properly. Please call MCI Technical Support at 1-
800-241-2947 for assistance.

The driver should inspect the radar and camera mounting brackets regularly and keep the
windshield and bumper locations clear of any mud, snow, ice build-up, or other obstructions.
The installation of aftermarket deer guards, bumper guards, snow plows or similar potential
obstructions is not recommended, and could impair the operation of the radar.

In cases where the bumper, radar and/or camera/mount area have sustained any damage, are
misaligned, or if you suspect that a device has been tampered with, DO NOT use the adaptive
cruise control until the coach has been repaired and the radar/camera re-aligned and cali-
brated. In addition, an indicator on the dash typically will illuminate if the system detects any
of these conditions.

Alarm and Fault messages for the Wingman® Fusion™ System will be displayed on the MCI Drive Scene screen
when the system detects a malfunction.

Any coach trouble code that disables vehicle cruise control will also cause a DTC in the Wingman®
Fusion™ System.

Safety Information

Safety technologies complement safe driving practices. No commercial coach safety

technology replaces a skilled, alert driver exercising safe driving techniques and proactive,
comprehensive driver training. Responsibility for the safe operation of the coach remains with
the driver at all times.

The driver is ALWAYS responsible for the control and safe operation of the coach at all times.
The Wingman® Fusion™ System does not replace the need for a skilled, alert professional
driver, reacting appropriately and in a timely manner, and using safe driving practices.

Under proper conditions, the Wingman® Fusion™ System will automatically activate the coach brakes if the
system determines an impact with a forward vehicle is likely to happen. Operating in cruise control is not required
for this automatic braking feature.

Safe Coach Operation Considerations

The Adaptive Cruise Control (ACC)

feature should not be used in cer-
tain operating conditions.

Safe Operation of the coach is ultimately the

responsibility of the driver.
• The driver should never rely on the ACB or
the CMT feature to completely bring the
coach to a stop.

• The driver should always be attentive to

passing or stopping vehicle’s to avoid a
collision.

• The driver should be fully aware of his or

her surroundings and be ready to apply the
brakes before the system engages the
brakes.

• The driver should be attentive to stationary

objects or stopped vehicle’s in the roadway.

Diesel Fuel System

DO NOT smoke or produce an open flame near or while handling fuel.

There are fuel filler neck doors located on each side of the coach and they are equipped with key locks. Unlock
the door and remove one side filler cap only to refuel. See "Figure 96: Filler Neck Doors Location" on page 117.

When servicing any of the diesel engine installations, refer to the applicable manufacturer's Diesel Engine
Service Manual. Fuel System components which require periodic maintenance include:
• Engine Air Cleaner
• Fuel Filters

Care must be taken when filling the fuel tank to prevent entry of dirt and water.

Diesel Fuel Specification

Engines must comply with EPA mandated low emission guidelines by using Ultra Low Sulfur Diesel (ULSD) Fuel.
Failure to use ULSD Fuel will result in component damage.

Diesel Fuel Contamination

The most common form of diesel fuel contamination is water. Water can be introduced to the fuel supply through
poor maintenance (loose or open fuel tank cap), a contaminated fuel supply, or condensation.

Use care in the storage and handling of diesel fuel to prevent contamination by dirt and water. Condensation is
particularly prevalent on units which stand idle for long periods of time. Ambient temperature changes can cause
condensation in partially filled fuel tanks. The Fuel System is equipped with a water sensor. Service is required if
WATER IN FUEL Indicator illuminates.

Diesel Exhaust Fluid (DEF) System

DO NOT put anything but DEF in the DEF tank (blue cap).

The Diesel Exhaust Fluid (DEF) tank is separate from the diesel tank, located at the rear curbside of the diesel
fuel tank. Unlock the DEF filler cap door and remove the blue color filler cap to refill. See "Figure 98: Diesel
Exhaust Fluid Filler Location" on page 119.

Diesel Exhaust Fluid (DEF) Specification

• DEF must meet ISO Standard 22241-1.f.

Use only American Petroleum Institute (API) or DIN certified Diesel Exhaust Fluid. This
ensures compliance with ISO 22241. Improper fluids or contaminated DEF may lead to high
nitrogen oxide emissions and damage the SCR System. Contaminated SCR Systems should be
serviced at an authorized dealer.
DO NOT use DEF beyond its expiration date or if it has been stored in conditions over 86°F
(30°C) for extended periods of time. This may cause degradation to the DEF.

DEF Reservoir Filling (General)

DO NOT pour any fluid/liquid into the DEF reservoir that is not DEF. The DEF reservoir is eas-
ily identified by its blue cap. Introducing any fluid/liquid that is not DEF can cause damage to
the engine and/or the SCR System.

Refill the DEF reservoir in a well ventilated area. Ammonia vapors have been known to escape when taking the
cap off of the fluid containing apparatus.

ALWAYS wipe down the filler cap and adapter before refilling the DEF reservoir to help prevent
contamination. DO NOT power wash the reservoir assembly.

DO NOT overfill the DEF tank, especially while in colder climates. DEF will expand approxi-
mately 10 to 15% of its standard room temperature volume when completely frozen, and will
cause damage to the tank. The recommended fill volume for exposure to temperatures at or
below 12°F (-11°C) is approximately 75% of the total volume at auto shutoff. These 75% levels
can be ensured by checking the output data given by the level sender. Due to the level sender
limits, (to ensure a reliable reading) turn coach off and then restart, allowing a few minutes for
the sender to adjust its reading if the level seems inaccurate.

Visually inspect DEF gauge on instrument panel daily. If level is low, DEF must be added. Locate the filler cap
access door on the coach curbside next to the fuel filler door, remove blue cap, and fill DEF tank. If DEF is
spilled, contain spill and absorb with a noncombustible absorbent such as sand. If DEF is spilled on coach, rinse
with water.

D45 CRT Operator - 6500629 119 Rev. A - November 2024

COACH OPERATION
DRAFT

To avoid potential fault conditions flagged by the system, it is important to fill the DEF tank
completely, however, DO NOT overfill the tank. Several fault conditions can be corrected by simply
keeping the tank full. NEVER operate the coach with the DEF tank cap removed. If a non-DEF
substance is accidentally introduced into the tank, the catalyst will recognize the contamination and
illuminate the DEF dash Indicator. If the level of contamination is too high, the coach may require
servicing.

If the DEF tank is not filled and is allowed to go empty, the coach speed will be limited to 5 mph.
Once filled, normal operation will resume.

DEF Reservoir Filling (Cold Weather)

During cold temperature filling, manually stop filling the reservoir before auto-shutoff levels.
DO NOT overfill the DEF reservoir assembly, especially while in colder climates. DEF will
expand approximately 10 to 15% of its standard room temperature volume when completely
frozen, and will cause damage to the reservoir assembly if it has been overfilled as well as
potential mixing of DEF and coolant.

If the reservoir is overfilled and freezes, the expansion of frozen DEF will cause catastrophic damage to the DEF
Reservoir System and/or coach SCR System. The recommended fill volume for coach’s that may be subjected to
temperatures at or below 12°F (-11°C) is approximately 75% of the total volume at auto-shutoff. These 75%
levels can be ensured by checking the output data given by the level sender.

Make sure that the cap and adapter are clean prior to cap removal and filling to help prevent
contamination. DO NOT overfill with DEF. This could cause spillage and/or overfill, which can
cause damage to the reservoir and/or coach. Clean any spilled DEF immediately with fresh
water to prevent corrosion to the system or coach components. DO NOT put DEF in the fuel
tank, or any fluid other than DEF in the DEF reservoir. This can cause engine damage and/or
damage to the SCR unit.

Filling the DEF reservoir with a fill station nozzle is similar to filling a tank with a normal fuel pump. Insert the
DEF station nozzle into the fill port and fill with DEF until the nozzle automatically shuts off.

The magnetic interface in the DEF reservoir allows filling at all approved DEF fill stations. The
interface is hidden within the cap adapter and allows the locking mechanism of certain station pumps
to be opened, allowing the DEF to flow unhindered.

Insert fill nozzle as far as possible into the fill port adapter to ensure proper auto-shutoff levels. Fill with DEF until
the nozzle automatically shuts off. Do not overfill, top-off, or try to fill the reservoir any further after the nozzle
has automatically shut off as this may cause issues with DEF expansion during cold weather conditions. During
cold temperature filling, manually stop station filling the reservoir before auto-shutoff levels. During regular
station filling, the fill nozzle will automatically shut off slightly below the fill port.

DEF Bottle Filling

Make sure that the cap and adapter are clean prior to cap removal to help prevent contamina-
tion. DO NOT reuse empty DEF bottle container or fluid. DO NOT store DEF container in the
coach because leaking DEF could cause damage to the interior and/or release ammonia
vapors.

The following applies to select DEF bottle filling apparatuses. Always consult the instructions on or included with
the bottle.

Insert bottle spout fully into fill port adapter and fill slowly to prevent overfilling. Stop filling when level is near the
auto-shutoff level achieved when station filling (slightly below the fill port). Only use bottle filling when necessary.

Bottle filling can still be used to fill the reservoir, regardless of a magnetic interface. The possession
or absence of a magnetic interface on the reservoir assembly will have no effect on bottle filling.

DEF Fill Cap

Make sure that the cap and adapter are clean prior to cap removal and filling to help prevent
contamination.

The cap on the DEF reservoir is a vented cap. When pressure reaches 4 psi, it is designed to release pressure by
venting to the atmosphere or to the tank. The DEF fill cap has an internal filter which cleans vacuum vented air
and prevents debris from entering the reservoir when it vents to the tank. If there are vacuum issues with the
reservoir, check the cap to make sure it is still functioning correctly and not damaged, otherwise, contact an SCR
System dealer. To check the fill cap, remove the DEF hoses and plug the DEF out/suction port to prevent any
leakage. Set up testing so that a vacuum is applied to the return/throttle line. The resulting venting should be
over 0.5 SCFH at 10 in. (254 mm) of water.

DEF Fill Cap Cleaning

Clean cap periodically to remove crystallization buildup. If vacuum is present when removing cap, clean cap as
soon as possible.

Wipe off cap and adapter and remove cap. Place cap in a bucket of water and allow to soak for five minutes.
While cap is submerged, shake vigorously to break up and loosen any residual DEF. Remove cap from water,
shake off excess water, and dry thoroughly with compressed air. Replace cap.

Exhaust Aftertreatment System

To avoid serious personal injury or property damage, ensure that no persons or objects are at
or within two feet of the exhaust outlet at any time during a regeneration. Ensure that exhaust
and outlet are clear of any trash, grasses, or other vegetation or debris.

Use extreme caution during a stationary regeneration, as exhaust gas tail pipe outlet
temperatures can exceed 900°F (482°C). Stationary regenerations are to be performed
outdoors only.

DO NOT leave the coach unattended during a stationary regeneration.

MCI coaches are equipped with a Diesel Particulate Filter (DPF) and a Regeneration System which work together
to reduce particulate emissions. The manual Regeneration switch is located at the curbside rear service door.

MCI coaches are equipped with three regeneration modes:

• Passive Regeneration - Normal engine operation provides sufficient exhaust temperature for
regeneration to occur with no noticeable effects to the driver.
• Active Regeneration - Normal engine operation does not provide sufficient exhaust temperature for
passive regeneration to occur. Regeneration System raises the exhaust temperature for regeneration to
occur.
• Stationary Regeneration - Normal operation of the engine will not allow for passive or active regeneration
to occur. The operator must initiate a regeneration with the Remote switch.

MCI coaches are equipped with two specific indicators for the DPF Regeneration System: See "Figure 99:
Regeneration Indicators" on page 123.
• Regeneration Indicator Lamp (DPF) - Indicator illuminates when a regeneration is required. Indicator is
OFF during regeneration.
• High Exhaust Temperature Indicator Lamp (HET) - Indicator illuminates when the coach is moving at a
low speed and the exhaust outlet temperature exceeds the predetermined level.

Engine Specific Regeneration Strategy

Before a parked or stationary regeneration can occur, these requirements must be met:
• The DPF Indicator lamp is illuminated (solid or flashing)
• Coach speed is 0 MPH
• While making a service brake application, cycle the push-button shift selector by pressing Drive [D] or Reverse
[R], then Neutral [N]
• The HVAC System is OFF
• The engine is running at idle speed (not fast idle)
• Parking brake is applied
• Service brake is released
• The exhaust and outlet are clear of any trash, grasses, or debris
• Press the REGEN START switch, hold for five seconds to initiate regeneration and center LED illuminates,
whereas LH LED is illuminated when a stationary regen is required and RH LED is illuminated when stationary
regen is active. Press the DPF REGEN STOP switch and hold to stop regeneration at anytime. Pressing DEF
REGEN STOP button stops regeneration and illuminates all 3 green LEDs. See "Figure 100: Regeneration

Stationary Regeneration Operation

During stationary regeneration, exhaust temperature may reach up to 1200°F (650°C) at the
particulate filter. Before initiating stationary regeneration, make sure that the DPF outlet
diffuser is clear of objects and that no one is working near the DPF outlet diffuser.

Keep yourself clear of all hot aftertreatment device components, particularly during and after
active or stationary regeneration. Hot surfaces can cause serious burns.

Diesel Particulate Filter (DPF) Indicator lamp will illuminate for 1 sec and turn OFF for the duration of
regeneration. Engine RPM will rise to 950 to 1050 RPM. HET Indicator lamp will illuminate after approximately, 3
minutes indicating high exhaust temperature during the regeneration and remain on until after the exhaust is
below the predetermined temp. Duration of the regeneration is 20 to 60 minutes depending on the level of soot in
the DPF. When the regeneration is completed, all indicators will be OFF, and engine RPM will return to idle.

A stationary regeneration can be interrupted by disabling one or more of the Stationary Regen requirements, or
by pressing the Regen switch to DISABLE position for 5 seconds, or turning OFF the Ignition switch.

An active regeneration can be interrupted by applying the parking brake, or placing the transmission in Drive [D]
or Reverse [R] gear.

Power Steering System

If the Power Steering System goes out because the engine has stalled or due to a hydraulic
failure, the coach can still be steered. However, much greater effort is required, especially in
sharp turns or in low speed.

This coach is equipped with hydraulic assisted steering to aid in input effort when steering the coach. The power
steering pump connects to the power steering reservoir and steering box through hose lines and fittings. The
power steering fluid reservoir can be accessed through the rear engine access door. See "Figure 101: Power

General Description
A wheelchair lift is located in the #2 baggage bay compartment on the curbside of the coach. See "Figure 108:
Wheelchair Lift (Ricon)" on page 132. See "Figure 109: Wheelchair Lift (Braun)" on page 132.

The lift provides safe on-loading and off-loading of wheelchair passengers with easy ground level access. The
platform raises to coach floor level where the passenger enters/exits the coach through the upper access door.

The lift is powered by an electrically operated hydraulic pump and operated with a hand-held controller. It can
also be operated manually by using the hand pump and manual control valves. The control box is located in the
#3 curbside baggage bay compartment. Keyed operation and a safety interlock prevent unsafe deployment.

To operate the wheelchair lift, the coach must be parked on a flat and level surface, coach
height being in Normal or Low Ride, and parking brake applied.

The wheelchair lift platform features:

• Folding handrails
• A manually operated front barrier
• The inner roll stop that acts as a bridge between the platform and the coach floor

The upper access door is located directly above the wheelchair lift storage compartment. The door has forward
sliding track and a positive lock mechanism to prevent accidental closing. The upper access door is operated
manually with the option of air powered assist.

Two wheelchair parking spaces are available next to and across from the lift platform. Sliding and folding seats
can be repositioned for wheelchair parking area. Refer to "Folding & Sliding Seats" on page 163 in this manual
for details.

A seven point Wheelchair and Passenger Restraint System is included at both wheelchair locations.

The electric pump, manual hand pump and control valves are located in the #3 baggage bay compartment.

Wheelchair Interlock System

This system prevents the WCL controller from being functional until the following conditions are met:
• The Main Battery Disconnect switch is in the ON position
• The engine is running
• Neutral [N] is selected on the transmission shift pad
• The parking brake is set
• Coach is in normal or low ride height
• Master Wheelchair Lift Key switch (located on the lower left-hand console switch panel) is turned to the ON
position

Only after these conditions are met, the following functions occur:
• Throttle is disabled

If the WCL INTERLOCK is blinking, DO NOT operate the lift. Check the text in the Message
Center and rectify the problem until the blinking stops. Must verify that the WCL INTERLOCK
indicator is staying on SOLID before proceeding to the lift.
• WCL INTERLOCK indicator illuminates SOLID
• Engine is running at fast idle
• Hazard/Warning lights automatically activate
• The audible back up alarm automatically activates
• Transmission shift inhibit and MDSS inhibit are energized
• The parking brake lock valve is energized
• The wheelchair lift exterior light illuminates
• The wheelchair controller is enabled

Whenever the Wheelchair Lift Key switch is in the ON position, an Interlock System prevents
releasing of the parking brake, transmission shift inhibit, and MDSS controls inhibit.

Threshold Warning System

The Threshold Warning System is located above the wheelchair parking (threshold) area. See "Figure 110:
Threshold Warning System" on page 134. The Module Status Indicator light illuminates when the wheelchair lift is
powered, indicating that the module is activated.

Two acoustic sensors monitor the doorway threshold area. If the acoustic sensors detect a passenger or an
object in the threshold area when the lift is below coach floor height and the cabin access door is open, an
audible buzzer and flashing light are activated. The lift operation will be halted until the area is cleared.

The normal platform motion with wheelchair and passenger aboard should not actuate threshold
warning.

 DRAFT WHEELCHAIR LIFT (OPTIONAL)

Manual Lift Operation (Ricon)

The lift can be operated manually if it loses electrical power. The following sections describe the lift controls
associated with manual operation, important safety preparations to be followed before using the lift, and
operating procedures to deploy, raise, lower, and stow the lift. It is recommended that manual operation be used
only to exit the vehicle, not to enter the vehicle.

Manual Lift Controls

Manual operation components consist of the following:

Hydraulic Backup Pump

• The manual backup pump is part of the hydraulic pump assembly, and is operated with a separate pump
handle. Pumping the handle raises the platform when the release valve is closed. A pump pressure
release valve for bleeding pressure from the hydraulic system is also on the hydraulic pump assembly and
is rotated with the pump handle. Opening the release valve lowers platform. See "Figure 114: Manual
Backup Pump & Handle" on page 140.
• The handle is also used to rotate the platform release shafts. Note that handle can be unfolded to gain
greater leverage when rotating release shafts.

Platform Release Shafts

• The stowed platform is difficult to withdraw against the resistance of the deployment system. For that
reason, a release mechanism and stow lock are provided to disengage the platform when manual
deployment is necessary. The platform is released by rotating either keyed release shaft in the direction
shown on the adjacent decal. The shafts are located behind cutouts at the left and right sides of the front
roll stop or will be visible behind the front roll stop. See "Figure 115: Platform Release Shafts" on
page 140.

Stow Lock

• The stow lock is a safety devise that secures the lift within the enclosure when stowed. The stow lock can
be manually disengaged by lifting the solenoid lever which will release the stow lock striker from the stow
lock catch. To manually release the platform, the keyed release shaft must be rotated 1/4 turn (as
indicated on adjacent decal) while lifting the stow lock lever. The stow lock can be located on the left or
right side of the lift. See "Figure 116: Stow Lock" on page 141.

Roll Stop Control Knob

• The manual roll stop control knob operates the platform roll stop directly. It is located on the right side of
the platform. Lower platform to the ground before attempting to lower, or open, the roll stop. Pull the
control knob out and turn it counter-clockwise to lower the roll stop. Close, or raise, the roll stop by pulling
the control knob out and turning it clockwise. Sometimes, closing the roll stop is easier if you lift the roll
stop with one hand, while turning the knob with the other hand. See "Figure 117: Manual Rollstop Control
Knob" on page 141.

Preparation:

• Park vehicle on a level surface, away from traffic. Allow sufficient space for lift operation and passenger
boarding.
• The operator must summon assistance to move vehicle to a safe operating area if a breakdown situation
exists and vehicle cannot be moved under its own power.
• Check to be certain obstacles are not in path of platform movement.
• Open vehicle doors by hand and secure.
• Caution people in vicinity that platform is about to deploy.
• Follow the Safety Precautions at the beginning of this chapter when a passenger enters or exits the
platform.

Manually Deploy Platform:

1. Obtain manual pump handle from its storage location, unfold, and engage either keyed release shaft located
behind access holes in rollstop. Rotate the shaft 1/4 turn (as indicated on adjacent decal) while lifting stow
lock lever simultaneously. See "Figure 118: Platform Release Shaft & Lift Stow Lever" on page 143.

NOTE:
Refer to adjacent decal for 1/4 turn orientation to disengage (open) keyed release shaft.

An able-bodied person must deploy the platform. Use caution and avoid injury.
2. Grasp the top edge of the front rollstop with two hands and pull firmly. The platform moves smoothly after an
initial resistance. Pull platform straight out to the end of its travel.

Ensure that release shaft re-engages and locks when platform is fully extended. If release
shaft does not engage, use manual pump handle and turn 1/4 turn (direction opposite to orien-
tation shown on adjacent decal) to re-engage release shaft.

3. For Dedicated Entry Models, lift right handrail to vertical and push firmly down into its socket. Repeat for left
handrail.

 DRAFT WHEELCHAIR LIFT (OPTIONAL)

Manually Lower Platform:

1. Verify that rollstop is up (closed). Pull rollstop control knob out and rotate clockwise, if it isn’t up.

DO NOT open pump release valve more than 1/4 turn. The valve will separate from the pump
body if unthreaded too far, which will disable both the automatic and manual pump functions.

2. Engage pump release valve with handle. Slowly rotate valve counter-clockwise (1/4 turn max) until platform
begins to lower; do not open further. Allow platform to settle on the ground, and then rotate valve clockwise
to close. See "Figure 121: Platform Lowering (counter-clockwise)" on page 146.

NOTE:
Do not over-tighten valve.

3. Pull rollstop control knob out and rotate fully counter-clockwise. Rollstop must lie flat on ground. See "Figure
122: Rollstop Opening (counter-clockwise)" on page 146.

4. Carefully assist passenger off of platform.

Manually Stow Platform:

1. Verify that pump pressure release valve is closed (CW). See "Figure 123: Release Valve Closing (clockwise)"
on page 147.

2. Raise the platform to stow height; position the top surface of the platform lifting frame arm at the same height
as the top surface of the carriage. If the exact height cannot be obtained, a slightly low platform is preferred
to slightly high. This alignment eliminates interference between the platform and enclosure when pushing the
platform into the enclosure. See "Figure 124: Lifting Arm & Carriage (same height)" on page 147.

3. Verify that rollstop is closed (fully up). Pull rollstop control knob out and rotate clockwise, if it isn’t up.

4. For Dedicated Entry Models, lift the left handrail upward out of its socket and then lower handrail to platform.
Repeat for right handrail.

An able-bodied person must stow the platform. Use caution and avoid injury.
5. Obtain manual pump handle from its storage location and engage either keyed release shaft located behind
the access holes in the rollstop. Rotate the shaft 1/4 turn (as indicated on adjacent decal).

NOTE:
Refer to adjacent decal for 1/4 turn orientation to disengage keyed release shaft.

6. Grasp the top edge of the rollstop, or the handrails, with two hands and push firmly. The platform moves
smoothly after an initial resistance. Push platform in fully.

The platform must lock in place when fully stowed. Check platform retention by attempting to
pull platform outward; it must not move.

7. If platform does not lock, rotate either platform release shaft 1/4 turn (direction opposite to orientation shown
on adjacent decal) to re-engage (lock) release shaft. Platform must be fully stowed before rotating shaft.

8. Verify that stow lock striker is engaged and platform is securely stowed.See "Figure 125: Platform Release
Shaft" on page 148.

Manual Lift Operation (Braun)

Manual operation should only be used for unloading passengers during a power failure. DO
NOT use the manual operation feature to do loading.

Instructions are provided for all steps that differ from standard lift operation procedures. Refer to the Lift
Operating Instructions for all normal lift operation procedures. Follow all Lift Operation Safety Precautions at all
times! Familiarize yourself with the components necessary to manually operate the lift. The T-handle release
cable releases and engages the lift platform to allow the platform to be manually extended and retracted. The
manual hand pump is used to manually lower and raise the extended platform. Location of the pump module is in
the #3 curbside baggage bay, and the T-handle release cable is located at the lift platform on the RH side.

Cable-Activated Platform Manual Release System

A cable-activated manual release system engages the platform carriage assembly drive chain. Disengaging the
drive chain allows the platform to be manually extended (out) or retracted (in). A T-handle is provided for
activation of the manual release.

After manually moving the platform in or out, the manual release must be positively re-engaged to lock the
platform. Push the T-handle in fully and ensure platform is locked. Grasp the outer barrier and move the platform
in and out until the platform locks. You will feel the release mechanism engage.

Uncontrolled and unintentional platform deployment (inadvertent platform ejection) may

result in serious bodily injury and/or property damage.

Ensure the platform is locked before driving lift coach. Failure to lock the platform carriage assembly will allow
the platform to roll in and out of housing unhindered during vehicle movement.

If not locked, the platform could also move in or out during hand pump raising and lowering
procedure.

Push the lift platform fully into the lift housing before resuming powered operation. Doing so provides
proper switch activation.

Electronic Engine Control System

This system controls the combustion process of the engine through timing and fuel metering relative to internal/
external sensor readings. The system continually monitors information from the electronic transmission control
system to achieve more fuel efficient shifting.

Various gauges are provided to show engine oil pressure and coolant temperatures, however, the electronic
control systems generally monitor conditions that could result in damage to the engine or that are dangerous to
coach operation. If during operation the system detects a serious condition (such as loss of water or oil), it will
alert the driver via the indicator warning lights. Audible alarms may also be installed to alert driver of serious
problems.

The system can be programmed to sequentially reduce power and shut engine down in case of serious engine
problems. An EMERGENCY OVERRIDE switch is provided to override the automatic engine shutdown system
and will allow engine to run for an additional 30 seconds so that coach may be moved to safe parking area. Use
the switch as often as necessary.

System Air Fill Connection
The system air fill connections consists of a standard quick disconnect fitting and a one-way check valve that
allow for filling of the entire air system. See "Figure 148: Rear Air Fill / Air Supply" on page 175. Compressed air
that is added through this fitting enters the system upstream from the cooling coil and air dryer and is therefore
dried and filtered before entering the remainder of the air system. The system air fill provision is located at the
rear of the engine compartment on the curbside, inside the service door.

Emergency Air Fill Provisions

The emergency air fill is to be used only in emergency cases on a disabled coach.

The emergency air fill provisions consist of standard quick disconnect fittings, each with its own one-way check
valve, that allow for filling of the primary and secondary air reservoirs and the parking brake system. See "Figure
149: Emergency Air Fill Provisions" on page 176. Compressed air that is added through these fittings enters the
system at the supply ports of the two-way check valve (parking brake valve supply) and is therefore not dried or
filtered before entering the service brake reservoirs and parking brake system. Because of the potential for
contaminated air being introduced into the coach air system when using these provisions, they should be used
only in emergency situations. The emergency air fill provisions are located on the left-hand front side service
compartment under the front junction box. The minimum pressure to fill is 105 psi.

Glad-Hands & Electrical Receptacle (Optional)

Two air line connections and an electrical receptacle are located on the roadside of the coach, beneath the front
junction box. They are mounted on a plate attached to the roadside coach wall and are accessed by unlatching
and lowering the front bumper. The bumper includes a prop rod that allows air lines to be safely routed without a
risk of pinches, snags, or kinks. See "Figure 150: Glad - Hands Towing Connection" on page 177.

The air line connections are color coded (red is for air supply and blue is for the service brakes). Air lines have
quick connectors. Included are dummy couplings to protect the system when not in use. The electrical receptacle
is a 7-pole socket. It functions to provide communication from the towing vehicle to the coach Multiplex System
providing turning signals, stop lights, and towing mode while the coach is being towed. This requires the coach
power to be active. If the coach does not have power, this receptacle will not function and other external
measures will be required for turn signals and stop lights.

from the rear can cause severe damage to the coach. MCI does not sanction lifting or towing
from the rear of the coach.

DO NOT lift the coach with tow eyes, they are to be used for off road or ditch extraction only.
Tow eyes at the front and rear of the coach are intended for the attachment of extraction or tie-
down cables only. Any other use may cause damage to the coach.

Towing Air Connections

An auxiliary air supply must be provided to the coach being towed to release the spring brakes and
maintain suspension height. The auxiliary air should be a minimum of 105 psi.

The connection points are in the roadside, front service compartment door below the junction box. See "Figure
156: Towing Air Connections" on page 183.

Towing Procedure

Route the hoses away from the steering gear and linkage. Ensure that the tow hoses will not
be pinched or damaged during towing.

1. Route the tow vehicle hoses to the coach connection points.

2. Attach the tow truck chains to the coach tow eyes and take up all slack.

3. Attach safety chains as applicable.

Observe the normal towing precautions including, but not limited to, the ones listed below
when towing the coach:

• Make sure the parking brake is released before towing by applying the service brakes.
• Do not allow a driver or passengers in the coach during towing.
• Do not exceed a prudent, safe towing speed. Be aware of changing conditions.

Tire Specifications
Recommended Tire Inflation Pressures
Ride characteristics and tire wear are affected by tire inflation. MCI recommends that the inflations shown on the
certification plate be followed for that size tire. Refer to "Replacement Tires & Tire Inflation (9.00" Rim)" on
page 190 in this manual for inflation pressures for tires other than those shown.

The tires listed below meet GHG regulations as LRR tires. It is the owner’s responsibility for tire
maintenance.
