NoteFor vehicles without stabilization control (ESC), during a TCS intervention the
control indicator in the instrument cluster flashes.
Electronic Differential Lock (EDL)
Read and observe
on page 109 first.
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes the spinning wheel, if necessary, and transmits the driving force to the
other driving wheel. Driving becomes easier on road surfaces with different
traction under each wheel of the driven axle.
The EDL switches off automatically in order to avoid excessive heat generation
on the brake of the wheel being braked. The vehicle can continue to be driven
and has the same characteristics as a vehicle not fitted with EDL. Once the
brakes have cooled down, there is an automatic re-activation of EDL.
Hydraulic Brake Assist (HBA)
Read and observe
on page 109 first.
The HBA increases the braking effect and helps to reduce the braking dis-
tance.
The HBA is activated by the very quick operation of the brake pedal. In order to
achieve the shortest possible braking distance, the brake pedal must be ap-
plied firmly until the vehicle has come to a standstill.
The HBA function is automatically deactivated when the brake pedal is re-
leased.
Hill Hold Control (HHC)
Read and observe
on page 109 first.
When driving on slopes, HHC allows you to move your foot from the brake ped-al to the accelerator pedal without having to use the handbrake.
The system holds the brake pressure produced by the activation of the brake pedal for approx. 2 seconds after the brake pedal is released.
The brake pressure drops gradually the more you operate the accelerator ped-
al. If the vehicle does not start off within 2 seconds, it starts to roll back.
The HHC is active from a 5% slope if the driver's door is closed. HHC is only ev-
er active on slopes when in forward or reverse start off.

Activation/deactivation
111
The parking aid (hereinafter referred to only as a system) draws attention via
acoustic signals and an indication in the radio or navigation display when ma-
noeuvring around obstacles in the vicinity of the vehicle.
The system uses ultrasound waves to calculate the distance between the
bumper and an obstacle. The ultrasonic sensors are integrated in the rear
bumper » Fig. 98 on page 111 .
WARNING■
The system only serves to support and does not relieve the driver of the
responsibility for the vehicle operation.■
Moving persons or objects may not be recognized by the system sensors.
■
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the system signals. For this reason, such people or
objects may not be recognised by the system sensors.
■
External noise sources may affect the signals of the system sensors. Un-
der adverse conditions, this may cause objects or people not to be recog-
nised by the system.
■
Before reversing, you should make sure that there are no small obstacles,
such as rocks, thin posts, trailer drawbars etc. behind your vehicle. Such ob-
stacles may not be recognised by the system sensors.
CAUTION
■ Keep the system sensors clean, snow-and ice-free and do not cover with any
objects of any kind, otherwise the system functioning may be impaired.■
Under adverse weather conditions (heavy rain, water vapour, very low or
high temperatures etc.), the system function may be limited - “incorrect recog-
nition of obstacle”.
■
Additionally installed accessories such as e.g. bicycle carriers can impair the
system function.

Operating Description
112
The Cruise Control System (CCS) maintains a set speed without you having to
actuate the accelerator pedal.
The state where the GRA maintains the speed is referred to hereinafter as the
control .
WARNING■
The GRA only serves to support and does not relieve the driver of the re-
sponsibility for the vehicle operation.■
Always adjust the speed and driving style to the current visibility, weath-
er, road and traffic conditions.
Functioning
Read and observe
on page 111 first.
Basic requirements for start of control The GRA is activated.
On vehicles with a manual transmission , the second gear or higher must
be engaged.
On vehicles with an automatic transmission , the selector lever must be in
the D, S position or in the Tiptronic position.

Read and observe on page 112 first.
For system-dependent automatic engine shutdown
to work, the following conditions must be met.
The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.
The driving speed was higher than 4 km/h after the last stop.
No trailer is coupled.
Some additional conditions for the system to function correctly cannot be in-
fluenced or recognised by the driver. Therefore, the system can react differ-
ently in situations which are identical from the driver's perspective.
If after stopping the car, the message START-STOP NOT POSSIBLE appears in
the segment display or the MAXI DOT display shows the
» Fig. 100 warning
sign, then the conditions for automatic engine shutdown are not being met.
Running the engine is essential for the following reasons, for example.
› The engine temperature for the proper function of the system has not yet
been reached.
› The charge state of the vehicle battery is too low.
› The current consumption is too high.
› High air-conditioning or heating capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).
Note■ If the vehicle remains outdoors for a long time in minus temperatures or in
direct sunlight, it can take several hours until the internal temperature of the
vehicle battery reaches a suitable temperature for proper operation of the
START STOP system.■
If the driver's seat belt is removed for more than approx. 30 seconds or the
driver's door is opened during stop mode, the engine will have to be started
manually.
■
After the manual engine start and with a manual gearbox the automatic en-
gine shutdown can take place only when a minimum distance required for the
system function has been covered.

Further information on automatic transmission
The automatic engine shut down takes place when the selector lever is in po-
sitions P, D , S and N and in Tiptronic mode.
When the selector lever is in position P, the engine remains shut down even
after you release the brake pedal. The engine starts automatically by pressing
the gas pedal or by moving the selector lever into a different mode and releas-
ing the brake pedal.
If the engine is off due to the automatic and the selector lever is put to the R
position then the automatic starts the engine.
If the gear selector is moved from position R to the position D, S or N, the vehi-
cle must reach a speed of more than 10 km / h before the automatic engine
shutdown starts.
There is no automatic engine shutdown when the system detects a vehicle
moving due to a large steering angle.
No automatic engine shutdown takes place when the vehicle is moving at low
speed (e.g. during a traffic jam or when tuning) and remains stationary after
pressing the brake pedal lightly. Automatic engine shutdown takes place if you
press the brake pedal down with more force.
System related automatic start-up
Read and observe
on page 112 first.
When the engine is off, the system can automatically start the engine beforethe desired journey continues. Some possible reasons for this are:
› The vehicle begins to roll, e.g. on a slope.
› The brake pedal has been actuated several times.
› The current consumption is too high.

Tyre pressure monitoring
Introduction
This chapter contains information on the following subjects:
Save tyre pressure values
115
The tyre pressure monitoring function (hereinafter referred to only as a sys-
tem) monitors the tyre pressure while driving.
If the rolling circumference of a wheel is changed, the warning light
in the
instrument cluster illuminates and an audible signal sounds.
Information on the procedure for the notification of change of tyre inflation
pressure » page 40 .
The system can only function properly if the tyres have the prescribed inflation
pressure and this pressure values are stored in the system.
WARNING■ Having the correct tyre inflation pressure is always the driver's responsi-
bility. Tyre pressure should be checked regularly » page 149.■
The system cannot warn in case of very rapid tyre inflation pressure loss,
e.g. in case of sudden tyre damage.
