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.

Optical Parking assistant (hereinafter only as a system) displays in Infotain-
ment the area to the rear of the vehicle monitored by the camera » Fig. 142 on
page 143 .
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
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.

Control is inactive (the numbers of the speed indications are small and of a
grey color).
Control activated - no vehicle detected.
Control deactivated - no speed stored.
Control active - vehicle is detected (the figures of the speed indications
are displayed larger or are highlighted).
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
Note■If control is started at a speed of less than 30 km/h on vehicles with an auto-
matic transmission, the speed of 30 km/h is stored. The speed increases auto-
matically to 30 km/h or is regulated with respect to the speed of the vehicle
ahead.■
When TCS is disabled, it will be activated automatically upon starting control.
■
If the TCS is deactivated during control, control is stopped automatically.

Note■If the proximity is changed in infotainment, the change will only come into
effect after a subsequent activation of the ACC.■
The proximity is dependent on the speed. The higher the speed, the greater
the proximity to the vehicle ahead.
■
On wet roads, a longer time interval to the vehicle ahead should always be
selected than on dry roads.
Special driving conditions
Fig. 152
Special conditions: Cornering / narrow vehicles or vehicles travel-
ling side by side
Fig. 153
Special conditions: Lane changes of other vehicles / stationary
vehicles
Read and observe
and on page 150 first.
The following and similar situations require special attention of the driver.
When cornering
When driving around long bends the ACC may respond to a vehicle in the adja-
cent lane » Fig. 152 -
. Your own vehicle is regulated with respect to this ve-
hicle and will no longer respond to the vehicle ahead.
In such cases, control should be disabled by accelerating, applying the brake or
pressing the button on the operating lever .
» Fig. 151 on page 152 .
Narrow vehicles or vehicles travelling side by side
Narrow vehicles or vehicles travelling side by side are not detected by the ra-
dar sensor until they are within the sensor's range » Fig. 152 -
.
If necessary, slow down the car by applying the brake.
Other vehicles changing lanes
Vehicles that change onto the lane with a small proximity » Fig. 153 -
do not
have to be detected by the radar sensor in time. The result may be a delayed
ACC response.
If necessary, slow down the car by applying the brake.
Stationary vehicles
The ACC does not detect stationary objects! When a vehicle detected by the
ACC turns or sheers off and there is a stationary vehicle in front of this vehi-
cle, » Fig. 153 -
the ACC does not respond to the stationary vehicle.
In such cases, take over the steering and stop the vehicle by applying the foot
brake.
When overtaking
When your vehicle is being controlled (the speed is lower than that which is
stored) and the indicator is activated, the ACC interprets this situation as
meaning that the driver intends to overtake. The ACC automatically acceler-
ates the vehicle, thereby reducing the proximity to a vehicle ahead.
If the vehicle changes to the fast lane and no vehicle is detected ahead, the
ACC accelerates until the set speed is reached and then keeps it constant.
Acceleration can be cancelled at any time by touch on the brake pedal or
pressing the button on the lever
» Fig. 151 on page 152 .
Vehicles with special load or special body parts
Other vehicles with a load or with body parts protruding from the sides, back
or top of the vehicle contour may not be detected by the ACC.
Control should therefore be disabled whenever you are driving behind or over-
taking such a vehicle. 154Driving
The pre-warning display can occur in the following situations.› If there is a risk of collision with a moving obstacle at a driving speed range
of approx. 30 km/h to approx. 210 km/h.
› If there is a risk of collision with a stationary obstacle at a driving speed
range of approx. 30 km/h to approx. 85 km/h.
When the advance warning is issued, the brake pedal must be pressed or the
moving obstacle avoided!
Acute alert
If the driver does not react to the advance warning, the system briefly applies
the brake automatically via an active brake intervention to draw attention to
the potential danger of a collision again.
Automatic Braking
If the driver fails to respond to the acute warning, the system starts to apply
the brakes automatically with increasing stopping power in several stages.
Brake Support
If the driver does not brake sufficiently in the event of an impending collision,
the system automatically increases the braking force.
The brake support only occurs as long as the brake pedal is being firmly press-
ed down.
Note
■ If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.■
The automatic braking interventions can be cancelled by pressing the accel-
erator pedal or by means of a steering intervention.
Activating/deactivating
Read and observe
and on page 155 first.
The function is automatically activated each time the ignition is switched on.
The system should only be disabled in exceptional cases »
.
The system can be activated or deactivated in one of two ways. › In the instrument cluster display
» page 51, Menu item wizard .
› In Infotainment
» Infotainment operating instructions , chapter Vehicle set-
tings (CAR button) .
The following functions can be activated or deactivated separately in infotain-
ment.
› Distance warning
› Advance warning
Once one of these functions has been deactivated, it remains disabled even
after switching the ignition off and on.WARNINGIn the following situations, Front Assistant should be deactivated for safety
reasons.■
When the vehicle is being towed away.
■
When the vehicle is on a rolling test bench.
