Traction Control System (TCS)Fig. 137
System button: Vehicle with ESC / vehicle without ESC
Read and observe
on page 138 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.
During a TCS intervention, the indicator light flashes in the instrument clus-
ter.
Activating/deactivating TCS
The activation or deactivation of TCS can be done, depending on equipment, in
one of the following ways.
› In Infotainment
» Operating instructions for Infotainment , chapter Vehicle
settings (CAR button) .
› By briefly pressing the symbol key
» Fig. 137 .
› By briefly pressing the symbol key
» Fig. 137 .
Upon deactivation, in the instrument cluster the indicator light lights up and
the display shows the following message.
Traction control (ASR) deactivated.
ASR OFF
Upon activation, in the instrument cluster the indicator turns and the display
shows the following message.
Traction control (ASR) activated.
ASR ON
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.
Note
On vehicles without the ESC system, the warning light
does not illuminate
upon deactivation of the ASR system, but a message is only displayed on the
display of the instrument cluster.
Electronic Differential Lock (EDL and XDS)
Read and observe
on page 138 first.
EDL
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. 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.
XDS
XDL is an extension to the electronic differential lock. XDL does not respond to
traction, but to the load relief of the inner front wheel of the driving axle dur-
ing fast cornering.
The automatic brake intervention on the brake of the wheel with reduced load
prevents the wheel from spinning. Thus, the traction is improved and the vehi-
cle can continue to follow the desired track.
Driver Steering Recommendation (DSR)
Read and observe
on page 138 first.
The DSR indicates to the driver in critical situations 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.
139Assist systems
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.
■
You should satisfy yourself before reversing that there is no small obsta-
cle, such as a rock, thin post, trailer drawbar etc., in front or behind your ve-
hicle. Such obstacles may not be recognised by the system sensors.
CAUTION
■ Keep the system sensors » Fig. 139 on page 141 clean, and free from snow
and ice, and do not cover with any objects of any kind, otherwise the system
functioning may be limited.■
Under adverse weather conditions (heavy rain, water vapour, very low or
high temperatures etc.), the system functioning may be limited - “incorrect ob-
stacle detection”.
■
Additionally installed accessories such as bicycle carriers can impair the sys-
tem functioning.

WARNING■
The system only serves to support and does not relieve the driver of the
responsibility for the vehicle operation.■
Make sure that the camera lens is not dirty or covered, otherwise the sys-
tem function can be significantly impaired. Information on clean-
ing » page 184 , Camera lens
CAUTION
■
The camera lens distorts and enlarges the field of view of the difference in
eye sight. The display is therefore only of limited use for estimating distances
to following vehicles.■
Some items, such as thin columns, chain link fences or lattice may not be
represented adequately in terms of display resolution.
■
It is only a two-dimensional display. Therefore, protruding objects or roadway
depressions, for example, may not be recognised due to lack of space depth.
■
In a crash or damage the vehicle's rear camera can possibly deviate from the
correct position. If this is the case, have the sensor checked by a specialist ga-
rage.

Park Assist (in the following referred to as the system) helps drivers park in
suitable parallel and perpendicular parking places and also to manoeuvre out
of parallel parking spaces.
The system takes over the steering movements when parking or driving out of
the parking space, the driver operates the pedals as well as the gear lever.
1)
The area behind the vehicle can be displayed for a few seconds more after disengaging the reverse gear.
144Driving
The state in which the steering wheel is operated by the system, is referred to
as parking operation.
The parking aid is part of the park assist system, therefore the information
and safety guidelines » page 140 , Parking aid must also be read and ob-
served.WARNING■ The system only serves to support and does not relieve the driver of the
responsibility for the vehicle operation.■
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 because of the surface
conditions. Therefore we suggest that you do not use the system in such
situations.
■
External noise sources may affect the signals of the system sensors. Un-
der adverse conditions, this may cause objects or people to not be recog-
nised by the system.
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.■
Under certain circumstances, surfaces or structures of certain objects such
as wire mesh fences or powder snow cannot be recognised by the system.
■
Under adverse weather conditions (heavy rain, water vapour, very low or
high temperatures etc.), the system functioning may be limited - “incorrect ob-
stacle detection”.
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.
■
Do without the use of the system if snow chains or a spare wheel is moun-
ted.
■
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.
NoteWe recommend performing the parking at a safe speed to about 5 km / h.
Functioning
Read and observe
and on page 145 first.
Basic system operations
› The measurement and evaluation of the size of parking spaces when driving.
› The determination of the correct position of the vehicle for parking.
› The calculation of the line on which the vehicle drives backwards into the
parking space or forwards from the parking space.
› Automatic rotation of the front wheels during the parking.
The display of the instrument cluster (hereinafter only in the display) informa- tion and system messages are displayed.
When the system is activated, the warning light lights up

145Assist systems
WARNING■The system only serves to support and does not relieve the driver of the
responsibility for the vehicle operation.■
The driver must always be ready to take over steering of the vehicle him-
self (accelerate or brake).
■
Always adapt your speed and safety proximity to the vehicle ahead to the
current visibility, weather, road and traffic conditions.
WARNING■ The ACC does not react when approaching a stationary obstacle, such as
traffic jams, vehicle breakdowns or vehicles waiting at a traffic light.■
The ACC does not respond to crossing or oncoming objects.
■
If the ACC does not decelerate fast enough, immediately apply the vehi-
cle's foot brake.
WARNINGFor safety reasons, do not use the ACC under the following conditions.■When driving in turning lanes, motorway exits or construction sites, to
avoid an unwanted acceleration to the stored speed.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
When driving around “sharp” bends.
■
When riding on a steep gradient / high slope.
CAUTION
The control may automatically switch off when some brake assist systems (e.g.
ESC) intervene, when the maximum permissible engine speed is exceeded, etc.
Note
■ The ACC is designed primarily for use on motorways.■The ACC reduces the speed by automatically releasing the accelerator or by
means of a braking procedure as appropriate. If the brakes are used for an au-
tomatic speed reduction at any moments, then the brake light illuminates.■
In case of failure of more than one brake light on the vehicle or on the elec-
trically connected trailer, the ACC becomes unavailable.
Radar sensorFig. 148
Mounting location of the radar
sensor
Read and observe and on page 150 first.
The radar sensor » Fig. 148 (From here on referred to as sensor) is used to as-
sess the traffic situation in front of the vehicle.
The sensor can distinguish objects by radiating and receiving electromagnetic waves.
The sensor function may be impaired in the events of one of the following.
› The sensor is covered by mud, snow or debris, for example.
› The sensor or its immediate surroundings are covered by other objects, for
example, a sticker is attached.
› When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
If the sensor is dirty or does not have “visibility” for any other reason, the fol- lowing message appears in the instrument cluster display » page 155.
WARNING■
If you suspect that the sensor is damaged, deactivate the ACC. Have the
sensor checked by a specialist garage.■
The sensor can become misaligned by collisions or by damage to the front
of the vehicle, the wheel arch or the underside of the vehicle. This can lead
to an impairment of the ACC function - risk of accidents! Have the sensor
checked by a specialist garage.
■
The area in front of and around the sensor must not be covered with
stickers, additional lights or similar items. This can lead to impaired function
of the sensor - risk of accidents!
150Driving
WARNINGThe sensor may not be able to distinguish all objects correctly under certain
circumstances. You should therefore not use ACC in the following cases -
risk of accidents!■
When driving through places where metal objects (such as metal build-
ings, railroad tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-ca-
pacity garages, car ferries, tunnels and the like.).
CAUTION
Remove the snow with a brush and the ice with a solvent-free de-icer.

The ACC can consistently maintain the set speed of 30-160 km/h, as well as
the proximity to the vehicle ahead ranging from a very small to a very long
time interval.
The ACC adjusts the set speed with respect to the detected vehicle ahead,
thus maintaining the selected proximity.
If the delay of the ACC is insufficient in relation to the vehicle in front, in the
instrument cluster, the warning light lights up and the display shows the
following message.
Apply the brake!
The ACC can detect a vehicle that is up to approx. 120 m ahead using the radar
sensor.
Note
Some ACC notifications in the display of the instrument cluster may be hidden
by notifications for other functions. An ACC notification automatically appears
for a brief moment when there is a change in status of the ACC.1234ABCD151Assist systems
