Under certain circumstances (e.g. after switching off the ignition and opening
the driver's door), the steering is enabled only when the ignition is switched on
or the engine is started.WARNINGNever let the vehicle roll with locked steering lock - there is a risk of acci-
dent!

START-STOP NOT POSSIBLEReasons for the engine running
It may be essential for the engine to keep running when the vehicle comes to
a halt, for the following reasons. ▶ 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).
When the engine is shut-down automatically and the system detects that the engine is required such as when the brake pedal is pressed repeatedly then
the system automatically starts the engine.
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.
■
No automatic engine shut-down takes place when a vehicle with automatic
transmission is moving at low speed (e.g. during a traffic jam) and remains sta-
tionary after pressing the brake pedal lightly. Automatic engine shutdown
takes place if you press the brake pedal down with more force.
■
For vehicles with automatic transmission there is no automatic engine shut-
down when the system detects a manoeuvring action due to a large steering
angle.

Assist systems
General information
Introduction
WARNINGThe following general information regarding the use of assistance systems
must be observed.■
The assistance systems only serve to support and do not relieve the driv-
er of the responsibility for driving the vehicle.
■
The increased safety provision, as well as the increased occupant protec-
tion provided by the assistance systems must not tempt you to take risks -
risk of accident!
■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.
■
The assistance systems have physical and system-related limitations. For
this reason, the driver may experience some undesired or delayed system
responses in certain situations. You should therefore always be alert and
ready to intervene!
■
Only activate, deactivate or set the assistance systems so that you have
the car fully under control in every traffic situation - risk of accident!

This chapter describes the functions of the brake and stabilization systems.
The error display is in Chapter » page 32, Warning lights .
The brake and stabilization systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.WARNINGThe general information relating to the use of assistance systems must be
observed » page 127, in section Introduction .
Stability Control (ESC)
Fig. 140
Press the ESC system: Activat-
ing/deactivating TCS
Read and observe on page 127 first.
The ESC improves vehicle stability in dynamic driving situations, such as when
the vehicle starts to skid.
The ESC monitors whether the desired direction of the current vehicle motion
is occurring. In case of any deviation (e.g. over steer), the ESC automatically
brakes individual wheels to maintain the desired direction.
During an intervention of the system, the indicator light
flashes in the in-
strument cluster.
The ESC system cannot be deactivated. The
» Fig. 140 button can only be
used to deactivate the TCS » page 128.
The warning light
lights up in the instrument cluster when the ASR is deacti-
vated.
Anti-lock braking system (ABS)
Read and observe
on page 127 first.
ABS prevents the wheels locking when braking. Thus helping the driver to
maintain control of the vehicle.
127Assist systems
The intervention of the ABS is noticeable from the pulsating movements of
the brake pedal which is accompanied by noises.
When the ABS system is active, do not brake periodically or reduce the pres- sure on the brake pedal.
Traction control (TCS)
Fig. 141
Button for the TCS system: TCS
disable / enable (vehicle without
ESC)
Read and observe on page 127 first.
TCS prevents the spinning of the wheels of the driven axle. TCS reduces the
drive power transmitted to the wheels in the case of slipping wheels. Thus, for
example, driving on road surfaces with low grip is made easier.
If your vehicle is fitted with the ESC system, the ASR is integrated into the ESC
system » page 127 .
During a TCS intervention, the indicator light flashes in the instrument clus-
ter.
The TCS should normally always be enabled. The system should be deactivated
only in the following situations, for example. ▶ When driving with snow chains.
▶ When driving in deep snow or on a very loose surface.
▶ When it is necessary to “rock” a car free when it has become stuck.
The ASR can be deactivated via the
» Fig. 141 symbol button.
The warning light lights up in the instrument cluster when the ASR is deacti-
vated.
Electronic Differential Lock (EDL)
Read and observe
on page 127 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.
EDL switches off automatically to avoid excessive heat generation on the
brake of the wheel being braked. Once the brakes have cooled down, there is
an automatic re-activation of EDL.
Driver Steering Recommendation (DSR)
Read and observe
on page 127 first.
In critical situations, the DSR provides the driver with a steering recommenda-
tion in order to stabilise the vehicle. The DSR is activated, for example, on the
right and left vehicle side when braking sharply on different road surfaces.
Brake Assist (HBA)
Read and observe
on page 127 first.
The HBA increases the braking effect and helps to reduce the braking dis-
tance.
The HBA is activated by 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 Start Assist (HHC)
Read and observe
on page 127 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.

Park Assist (hereinafter referred to as system) helps drivers park in suitable
parallel and perpendicular parking places or also to manoeuvre out of parallel
parking spaces.
The system takes over the steering movements when parking or leaving a
parking space. The driver operates the pedals and the shift lever or gear selec-
tor.
The state in which the steering wheel is operated by the system, is referred to
as parking operation.
The Park Assist is an extension of the parking aid » page 131 and operates on
the basis of data collected by the ultrasonic sensors.
For this reason, the chapter on the parking aid is to be read carefully and the safety notes are to be observed.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 127, in section Introduction .■
During the parking process, the system automatically performs rapid
steering movements. While it is doing so, do not place your hands between
the steering wheel – risk of injury!
■
During a parking manoeuvre on loose or slippery surfaces (gravel, snow,
ice, etc.) you may stray from the calculated road. Therefore we suggest that
you do not use the system in such situations.
CAUTION
The correct evaluation of the parking space and the parking procedure de-
pends on the circumference of the wheels on the vehicle.■
The system only works correctly if the vehicle is fitted with the wheel size
approved by the manufacturer.
■
Abstain from using the system when the vehicle is fitted with snow chains or
a temporary spare wheel.
■
If wheels other than those approved by the manufacturer are mounted, the
resulting position of the vehicle in the parking space can differ slightly. This
can be avoided by readjusting the system at a specialist garage.
CAUTION
If other vehicles are parked behind the kerb or on it, the system can also guide
your vehicle beyond the kerb or onto it. Ensure that the wheels or the wheel
rims of your vehicle are not damaged and if necessary intervene in time.
Note
■ We recommend performing the parking at a safe speed to about 5 km / h.■The driver can stop the parking process at any time by pressing the symbol
key
» Fig. 149 on page 136 or by a driver steering intervention.
