 In Brief

Where is the Jetta 2011 EU produced?

The Jetta 2011 EU is produced at Volkswagen’s Puebla plant in Mexico.
This factory opened in 1964 and initially produced the VW Beetle.
The Puebla site currently has a workforce of around 15,000; they build among others

– the New Beetle,

– the Jetta
– and the Golf Estate (also as Jetta Estate for some markets).

The Jetta 2011 EU replaces the Jetta 2006.

S492_006

S492_005

At the Puebla plant, which is equipped with the very latest technology, a constantly high quality standard is
guaranteed by modern production lines combined with a modular manufacturing strategy. The plant is one of
Volkswagen’s leading production sites.

The engineers at Puebla played a major role in the preparation and development stages of the new Jetta as well as
in the preparations for the actual production.

The Jetta 2011 EU is built with the existing production facilities for the Jetta 2006 in Mexico.

History of the Jetta
The Jetta series can look back on a long success story that now stretches back 30 years. This not only concerns the
vehicle’s technology and exterior appearance, but also the model name. After temporary changes of name, the
model series has been produced again under the internationally very successful “Jetta” name since the fifth
generation.

1979 – Launch of model series – Jetta 1

1984 – 2nd generation – Jetta 2

 Body

Body structure
The body structure of the Jetta 2011 EU has been
systematically further developed particularly in terms
of requirements for

● lightweight construction
● vehicle safety
● sportiness
● comfort and
● quality

A considerable weight reduction has been achieved S492_009

compared with the previous model. At the same time,
the new body structure provides an all-round high
level of crash safety and body stiffness superior to the
competition. The weight reduction achieved supports
the efforts of Volkswagen Group to reduce CO2
emissions.

Lightweight construction
The lightweight construction aims have been met with

● optimum use of ultra-high-strength and

thermoformed steels
● reduction of panel thicknesses and
● refined design optimised through computer
modelling

This therefore breaks the generally recognised trend

of “larger, more comfortable vehicles being heavier”
in a convincing manner.

The weight-reducing measures can be divided into three groups.

● The main part of the reduction results from widespread use of thermoformed parts in the floor structure,
the B-pillar and the roof frame.

● One further important measure is the reduction of the material thickness of body parts that are subjected to
lighter loads, for example, the outer skin parts – the performance characteristics are retained, however.

● In the third measure, the engineers made sure that positive effects to save weight were created in the body
configuration throughout the design phases. For example, weight can be saved with clean profiles and smaller
reinforcements in the “right places”.

 Body

Body stiffness
The body structure of the new Jetta 2011 EU meets higher expectations in terms of acoustic and vibration behaviour
thanks to the particularly stiff body configuration.

This has been achieved with

● Specific structural design of the nodes and force transmission points

● Optimum use of available construction space by employing three-part structure throughout – the passenger
compartment is thus enclosed by computer-optimised body profiles.

Static torsional rigidity (Nm/°)

Competitors

S492_012

Torsional frequency (Hz)

The body structure of the Jetta 2011 EU is characterised by outstanding static torsional rigidity. The same applies to
the dynamic rigidity.

The Jetta 2011 EU therefore clearly stands out from its competitors.

The high level of body rigidity benefits in particular the acoustics, the vibration characteristics and the excellent ride
comfort of the new Jetta.

12
Crash-safe body design
One major focus of development was that a high level of crash safety is also ensured in the measures to increase
body stiffness.

Therefore, in conjunction with the lightweight construction measures, a special combination of materials with
varying degrees of deformability is specifically used for respective sections of the body.

Specially adapted paths of force transmission and energy-absorbing deformation zones were created during the
design of the body. This guarantees that the transmission of force in a crash follows a defined pattern.

The body structure has been designed so that it ensures optimised transmission of force in frontal collisions as well
as in side and rear collisions.

The two illustrations show transmission of force using a frontal collision as an example.

 Body

Body features
The body of the Jetta 2011 EU has completely new Front seats
exterior contours and thus meets the market-specific
requirements very well. The front seats with manual adjustment now have a
locking device for setting the backrest inclination.
Depending on the equipment options, a manually
adjusted 2-way lumbar support or an electrically
adjusted 4-way lumbar support can be fitted.
Electrically adjusted seats are optionally available for
Bonnet
the Sportline version.

The Bowden cable for opening the bonnet is routed

out of reach in the engine compartment.

Space concept

The larger vehicle interior gives you a completely

new feeling of space. This has been made possible
by making the vehicle longer, increasing the
wheelbase and making the interior wider.
The lowered beltline also gives a greater feeling of
space in the back.
The luggage compartment is generous. The load
sill has been lowered and the opening made
wider.

Headlights

The headlights on the Jetta 2011 EU feature clear

glass technology. The daytime running lights and turn
indicators have been placed below the dipped beam
and main beam lights as before.

Doors Roof

The doors on the Jetta 2011 EU have a conventional Depending on the equipment, a sliding/tilting sunroof
design. Side impact bars are installed in all doors. and, at the rear, the roof aerial with the telephone
aerial (GSM), the auxiliary heater aerial and the
navigation system aerial (GPS) are fitted in the roof.

Rear lid

The rear lid is opened from the outside with a

microswitch in the rear lid handle.
The rear lid lock is equipped with an emergency
release. This consists of a swivel plate that has to be
rotated from inside the luggage compartment to open
the lid.

15
 Occupant Protection

Safety equipment
The Jetta 2011 EU essentially has the following safety equipment:

● Driver airbag ● The seat occupied recognition system is the same

● Front passenger airbag as that used in the new Passat and Sharan.
● Side airbags at front
● Head airbags for front and rear occupants
● Belt tensioners and belt force limiters on the front
seats

● Optimised sensor system for crash recognition

(evaluation of structure-borne sound in crashes)

● There are sensors in the front doors and in the vicinity of the
C-pillar for detecting side collisions.

16
● Top Tether
The Jetta 2011 EU is equipped with the Top Tether system. The Top Tether system
serves to secure a child seat more firmly. In this case, an additional upper belt on the
child seat is attached to corresponding anchors on the luggage compartment cover.

S492_026

 Occupant Protection

Optimised sensor system for crash

recognition
The crash sensors need to respond within a few
milliseconds in severe frontal collisions so that the Airbag control unit J234
airbag control unit can immediately initiate
deployment of restraint systems.

This rapid procedure is absolutely necessary so that

the airbags can inflate completely and thus protect
the occupants in an optimum way.

On the other hand, in less serious accidents, for

example, car park bumps, airbag deployment is
avoided as airbag protection is not needed in this
case. This helps prevent unnecessary repair costs.

The latest sensor systems for crash detection measure

the deceleration of the vehicle and then determine
whether the airbags or belt tensioners should be
deployed.

The Jetta 2011 EU now uses a new innovative sensor

system for crash recognition.

Structure-borne sound

18
 How does the new sensor system for crash
recognition work?

As more extensive electronic functions become

available through technical progress, an increasing
number of new more refined evaluation processes are
becoming possible. This is also true of the crash
sensors and their evaluation.

Function procedures

● The airbag control unit J234 located centrally in

the vehicle interior evaluates the low-frequency
palpable deceleration signals using the crash
sensors integrated into the control unit.
● In addition, specially adapted, highly integrated
acceleration sensors measure the frequency
components in the medium “audible” frequency
range up to 20kHz. These signal components are
formed from structure-borne sound during the fast
deformation of supporting structures in the front
end of the vehicle.
They spread through the body structure at high
speed and very quickly provide precise
information about the severity of the crash.
● The crash characteristics can be determined more
quickly by intelligently linking the palpable and
audible signal components within the crash
algorithm.
S492_107
This highly sensitive sensor system for crash
recognition allows the deployment of airbags and belt
tensioners to be adjusted better to the actual crash
situation and the vehicle occupants to be given
optimum protection in crashes.

Self-study
7-speed dual clutch gearbox 0AM
programme
390
The 7-speed dual clutch gearbox 0AM has been developed from
the 6-speed dual clutch gearbox 02E.
In contrast to the 02E gearbox, it works with a dry dual clutch and with
separate oil circuits for gearbox and mechatronics.
Also in contrast to the 02E gearbox, electric oil pump for the hydraulics is
only activated on demand by the control unit.
It is activated when the hydraulic pressure in the mechatronics falls below
a certain value and the pressure needs to be raised again to guarantee
correct functioning of the mechatronics.

The external steering angle sender G85 has been omitted on this steering system. Within the electromechanical
power steering system, the sensor information is composed of the individual signals

● from the integrated index sensor and

● from the rotor position sensor. (The sender magnet for the sensor is located on the motor shaft of the
electromechanical power steering motor V187 and the sensor element is located in the power steering control
unit J500.)

The steering angle of the vehicle is calculated from all of this information in the power steering control unit J500.
The calculated steering angle is used for the internal steering functions and is also supplied to other control units as
a substitute for the G85 value.

Tyre pressure monitor (TPM)

The TPM tyre pressure monitor is a software module in
the ABS control unit, which evaluates the data from
the ABS wheel speed sensors to monitor the tyre
You can find out about the TPM tyre
pressures. A new tyre pressure monitor, which has

is being used in the Jetta 2011 EU for specific markets.
Systems”.

Function
The rolling radius of a wheel decreases as the tyre
inflation pressure falls and the wheel rotates faster at
the same vehicle speed.

The wheel speed sensors calculate the speed

difference, which is then evaluated in the ABS control
unit J104. A warning lamp in the dash panel insert
and an acoustic signal informs the driver and asks
him to check the tyre pressure. Control unit in dash
panel insert
The resonant frequency of the tyres is measured in
ABS control unit with
addition to the speed. This produces a more precise integrated software for
evaluation of the pressure loss. The tyre pressure tyre pressure monitor
monitor is capable of recognising creeping pressure (TPM)

loss at several wheels at the same time. Button for tyre pressure
monitor
Since the characteristics of each individual tyre are
different, calibration is necessary to determine the
reference data for the currently fitted tyres and the
pressures currently stored in the system.

The system also needs to be re-calibrated after the

tyre pressure is changed at one or more wheels.
S492_043
The same applies if a wheel is changed. Then the
inflation pressure needs to be set to the required level
and the system should be re-calibrated for this
pressure.
Snow chain recognition

The system is not active if snow chains are detected.

36
Calibration
With the ignition switched on, press the tyre pressure
monitor button until you hear a confirmation tone. The
tyre pressure values recorded during calibration are
now stored in the tyre pressure monitoring system as
required tyre pressures.

The tyre pressure monitor button is located at the top

left of the glove compartment.

During calibration make sure that the tyre

pressure prescribed for the vehicle is set
S492_044
at the respective tyre.

Display – warning
If the pressure falls by a certain value below the
required tyre pressure stored during calibration, the
driver will receive a warning from the system. The
warning is signalled by a gong and the yellow
warning lamp for the tyre pressure monitor in the
dash panel insert.

The lamp remains lit until the system is recalibrated.

The gong will sound each time the vehicle is started
until recalibration is performed.
S492_045

When a vehicle is serviced, service staff must inform the driver that he himself is responsible for setting
the correct tyre pressure. The tyre pressure monitor is an information system that provides a message if
pressure is lost at one tyre. It does not, however, relieve the driver of his responsibility to check the tyre
pressures on a regular basis.

 Electrical System

Electrical interfaces

The onboard supply control unit includes – as on a basic model without “Keyless Access” locking and start system –
– the electronic module with high-frequency receiver (wireless receiver) for the central locking system. The onboard
supply control unit is integrated into the CAN data bus via which various coordination processes occur, information
is exchanged etc. within the system. Additional components are the electronic steering column lock (ESL) with its
own control unit and the entry and start authorisation control unit J518 (“Keyless Access”) including aerials, door
handles and the vehicle key (ID sender).

Driver interfaces

The “Keyless Access” locking and starting system takes care of recognition and identification of the key both outside
and inside the vehicle. The aerials fitted in the front door handles and in the vehicle interior are used to set up the
connection between the vehicle key and the “Keyless Access” system. The following functions are available after
successful identification:

● Keyless Entry – Unlock vehicle via driver or front passenger door handle – take hold of handle [A].
The ID sender must be located within the exterior monitoring area on the corresponding side of the vehicle or at
the rear of vehicle.
● Keyless Go – Start the engine and drive – a valid ID sender must be located inside the vehicle.
If you want to start the vehicle, press the starter button and the clutch (if vehicle has a manual gearbox) or the
brake (if vehicle has an automatic gearbox).
● Keyless Exit – Lock vehicle upon leaving the vehicle – driver door must be closed.
Press the outer button on the handle of the driver or front passenger door [B]. If the vehicle is locked via the
front passenger door, it must be closed. The ID sender must be located within the exterior monitoring area on
the corresponding side of the vehicle or at the rear of vehicle.

 Electrical System

Start/stop system
The start/stop system, which was used for the first time at the start of the eighties in the Passat Formel E as well as in
the Golf Ecomatic (1993) and in the Lupo 3L (1999), is now being used in all vehicle classes at Volkswagen in the
form of an updated generation.

The proven start/stop system will therefore also be available as an optional extra for the Jetta 2011 EU.

The basic advantages of the system are the following:

● The engine does not run at idle unnecessarily.

● The fuel consumption and the harmful emissions are reduced in city traffic and in
stop-and-go traffic.
● The noise emissions are reduced to zero when the vehicle is stationary.

Function overview
The start/stop system works in a very simple way – also in terms of customer friendliness.

● If you shift into neutral while the vehicle is stationary and release the clutch pedal, the engine will switch off
automatically.
● When you want to continue driving, you just have to press the clutch pedal to start the engine.
● You can quickly continue the journey after selecting a gear.

S492_113

The function overview shows how the start/stop system works using a manual gearbox as an example.

46
Regenerative braking
The start/stop system has been combined with the “regenerative braking” function from the BlueMotion Technology
package to make it even more efficient. The regenerative braking function supports an efficient supply of electrical
energy to the vehicle electrical system.

What does regenerative braking mean?

Regenerative braking refers in general to the recovery of energy during braking.

This recovered energy is supplied to the battery to charge it.

Regenerative braking is controlled by a system of control units and sensors, among which the engine control unit
J623 and the data bus diagnostic interface J533 perform the main tasks.

Overrun

During overrun – when braking – the kinetic energy of the vehicle is used in an optimum way to charge the battery.
For this purpose, the alternator is controlled so that it produces a high charging voltage.

Acceleration

On the other hand, low voltage is set at the alternator during acceleration.
