» Fig. 275 .
▶ Your vehicle
C
overtakes the vehicle
D
at a greater speed of max. 10
km » Fig. 276 . If the speed during the overtaking is even higher, then there is
no warning by the warning light.
The warning display is always in the exterior mirror on the side of the vehicle where a vehicle is detected in the “blind spot”.
The greater the speed difference between the two vehicles, the earlier the
warning (by means of the warning light) regarding the vehicle that is overtak-
ing you takes place.
Two warning levels
light up - a vehicle has been detected in the “blind spot”.
flash - a vehicle has been detected in the “blind spot” and the turn signal is
switched on .
An advanced warning for vehicles with Lane Assist
flash also if the steering wheel is turned in the direction of the vehicle in
the “blind spot” . Therefore the Lane Assist » page 254 must be enabled and
the boundary line between the vehicles detected.
If in this case your vehicle indicates crossing the boundary line, with a short vi-
bration of the steering wheel.
NoteThe brightness of the indicator light is dependent on the setting of the ve-
hicle lighting. With the low or high beam on the brightness of the light will be
lower.

The rear view camera (following as system) helps the driver when parking and
manoeuvring by displaying the area behind the vehicle on Infotainment screen
(hereinafter only known as screen).
There are four modes available for different situations during the park and ma-
noeuvring action. The mode change is carried out using the function surfaces
on the screen » page 228.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 215, in section Introduction .■
The system detects obstacles. The display of the auxiliary boxes and lines
is independent of the actual vehicle environment. The driver must judge for
themselves whether the vehicle can park safely in the selected parking
space.
■
The camera may not be soiled or obscured, otherwise the system function
will be significantly affected - there is a risk of accident. For information on
cleaning » page 271 .
CAUTION■
The camera image is distorted by contrast with eyesight. For this reason, the
screen display is only of limited use for estimating distances to following vehi-
cles.■
Some items, such as thin posts, chain link fences, grilles or uneven road sur-
faces may not be properly displayed in terms of screen resolution.
■
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.
Note
The camera is equipped with a cleaning system » page 75. The spraying is car-
ried out automatically when the rear window is sprayed.

Park Assist (following referred to 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 only when parking or leaving a
parking space. The driver operates the brake, accelerator or clutch pedal and
the shift / selector lever.
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 220 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.

The Adaptive Cruise Control (hereinafter referred to as ACC) maintains the set
speed or the distance to the vehicle ahead without the accelerator or brake
pedal being pressed.
The front of the vehicle and the distance to the vehicle ahead is monitored by
a radar sensor » page 215.
The state in which the ACC maintains the speed or the proximity is described
as control from here on.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 215, in section Introduction .■
The driver must always be ready to take over the operation of the accel-
erator and brake pedal.
■
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).
■
Driving in “sharp” corners or in steep gradients / on steep inclines.

Note to reduce speed
If the delay of the ACC is insufficient in relation to the vehicle in front, the
warning light lights up in the instrument cluster and the display shows a
message to engage the brake pedal.
Regulation according to the vehicle in the adjacent lane
During regulation your vehicle may be regulated according to the vehicle in the
adjacent lane.
This could occur at speeds above about 80 km/h when your vehicle is moving
faster than the vehicle in the adjacent lane on the driver's side. The display
shows the detected vehicle is in the adjacent lane.
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.
Automatic stopping and starting
Read and observe
on page 243 first.
Vehicles with an automatic transmission can decelerate to a standstill and
start moving again using the ACC.
1234Decelerate to a standstill
If a vehicle ahead decelerates to a standstill, the ACC will also decelerate your
vehicle to a standstill.
Starting to drive again after a holding period
As soon as the vehicle ahead starts moving again after a holding period, your
vehicle will also move and the speed will continue to be regulated.
If the vehicle in front starts moving again after a long break, press the acceler-
ator pedal or set the lever to position
in order to continue control
» page 245 .

Special driving conditions
Fig. 307
Cornering / narrow vehicles or vehicles travelling side by side
Fig. 308
Lane changes of other vehicles / stationary vehicles
Read and observe
on page 243 first.
The following (and similar) situations require special attention and possibly the
intervention of the driver (braking, accelerating etc.).
When cornering
When driving into or driving out of long corners, it could be that a vehicle is
travelling in the adjacent lane and is scanned by the radar » Fig. 307 -
. The
host vehicle is then controlled according to this vehicle.
Narrow vehicles or vehicles travelling side by side
A narrow or offset vehicle driving can only be recognized by the ACC if this is
located in the scanning range of the radar » Fig. 307 -
.
Other vehicles changing lanes
Vehicles that change onto the lane with a small distance » Fig. 308 -
may
not be detected by ACC in good time.
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 vehicle,
» Fig. 308 -
the ACC does not respond to the stationary vehicle.
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.
Overtaking and towing
Read and observe
on page 243 first.
When overtaking
When your vehicle is being controlled at a speed that is lower than the set
speed and the turn signal is operated, ACC assesses this situation as meaning
that the driver wishes to overtake. The ACC automatically accelerates the vehi-
cle, thereby reducing the proximity to a vehicle ahead.
If your vehicle changes to the overtaking lane and no vehicle is detected
ahead, ACC accelerates until the set speed is reached and then keeps it con-
stant.
Acceleration can be cancelled at any time by touch on the brake pedal or
pressing the button on the lever
» Fig. 306 on page 245 .
Towing a trailer
When towing, or if another accessory is connected to the trailer socket, ACC
control is set with a lower rate. The manner of driving should therefore be
adapted to this limitation.
247Assist systems
The first protection level can be deactivated in one of the following ways.
▶ in the menu Infotainment
→ →
Driver assistance
.
▶ Deactivating the TCS » page 217.
▶ By selecting the driving mode
Sport
» page 252 .
Provided that the driving mode
Sport
is not selected, the system is activated
over the two levels of protection after switching the ignition off and on again.
The second level of protection
The system intervenes only if the situation is evaluated as critical, such as
when panic braking at high speeds.
This level of protection cannot be deactivated.
Vehicles with the Front Assist system
Using this information, a system intervention may also occur when there is the danger of a collision with an obstacle detected in front of the vehicle.

The lane departure warning (following known as system) helps to keep the ve-
hicle between the boundary lines of a lane.
The system recognises the boundary lines of the lane using a sensor » Fig. 313.
When the vehicle approaches a detected line between lanes, the system
makes a light movement of the steering wheel in the opposite direction to the
boundary line. This corrective steering intervention can be manually overrid-
den at any time.WARNING■ Please take note of the general points relating to the use of assistance
systems » page 215, in section Introduction .■
Lane Assist can help you keep the vehicle within the lane. However, it
does not steer the vehicle for you. The driver retains full responsibility for
steering at all times.
■
Some objects or markings on the road can be recognised as the boundary
lines - an erroneous steering intervention may be the result.
WARNINGThe system may not be able to recognise the boundary line, or recognise it
incorrectly, for example, in the following situations.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When driving in “sharp” bends.
■
The sensor is blinded by the sun or oncoming traffic.
■
The field of view of the sensor is limited by an obstacle or a preceding ve-
hicle.
CAUTION
Do not attach any stickers or similar objects in front of the sensor on the wind-
screen to avoid impairing the functions of the system.
Note
■ The system is designed for driving on motorways and roads with adequate
longitudinal markings.■
The system can detect both continuous and broken lines.
