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.

AB143Assist systems
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.

At the start of the control process, the CCS regulates the vehicle to the current
speed, and this speed is shown on the instrument cluster display. The warning
light illuminates in the instrument cluster.
Automatic control interruption
Automatic control interruption occurs if any of the following conditions are
met.
› The brake pedal is operated.
› When one of the brake assist systems (e.g. ESC) intervenes.
› Through an airbag deployment.
WARNING■
Always deactivate the cruise control system after use to prevent uninten-
tional switching on of the system.■
Control may only be resumed if the set speed is not too high for the cur-
rent traffic conditions.
Note
During control, speed can be increased by pressing the accelerator pedal. Re-
leasing the accelerator pedal will cause the speed to drop again to the set
speed.

Adaptive cruise control (from here on referred to only as ACC) can maintain the
set speed or the proximity to the vehicle ahead consistently, without the need
to operate the gas or brake pedals.
The state in which the ACC maintains the speed or the proximity is described
as control from here on.
149Assist 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.

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 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
Towing a trailer
When towing a trailer, the ACC control will be less powerful. The manner of
driving should therefore be adapted to this limitation.
Information messages

157The Front Assistant (from here on only referred to as the system) warns you of
the danger of a collision with a vehicle or another obstacle in front of the vehi-
cle, and tries to avoid a collision or mitigate its consequences by automatically
applying the brakes where necessary.
The area in front of the vehicle is monitored by a radar sensor » Fig. 154 on
page 155 .WARNING■
The system only serves to support and does not relieve the driver of the
responsibility for the vehicle operation.■
The system has 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 inter-
vene!
■
Always adapt your speed and safety proximity to the vehicle ahead to the
current visibility, weather, road and traffic conditions.
■
The increased passenger protection afforded through the system must
not tempt you to take greater risks than otherwise – risk of accident!
■
The system does not respond to crossing or oncoming objects.
CAUTION
In case of failure of more than one brake light on the vehicle or on the electri-
cally connected trailer, the system becomes unavailable.
