The warning lights in the instrument cluster indicate certain functions or
faults.
Some warning lights can be accompanied by acoustic signals and messages in
the display of the instrument cluster.
After switching on the ignition, some warning lights light up briefly as a func-
tion test. If the tested systems are OK, the corresponding warning lights go
out a few seconds after switching on the ignition or after starting the engine.
The warning lights are located at the following positions in the instrument
cluster » Fig. 17 on page 30 .

flashes for approximately 1 minute and remains lit – there may be a fault in
the tyre pressure monitoring system.
▶ Stop the vehicle, turn the ignition off and start the engine again.
If the warning light
flashes after starting the engine again, there is a system
error.
▶ You can drive on, exercising appropriate caution. Seek assistance from a spe-
cialist garage immediately.
Disconnecting the vehicle battery
If the vehicle's battery has been disconnected and reconnected, the indicator
light comes on after switching on the ignition.
The warning light should go out after driving a short distance.
If, after a short drive, the indicator light does not go out, there is a system er-
ror.
▶ You can drive on, exercising appropriate caution. Seek assistance from a spe-
cialist garage immediately.
Other incidents
The illumination of the warning light can have the following reasons.
▶ The vehicle is loaded on one side. Distribute the load evenly.
▶ The wheels of one axle are loaded more heavily (e.g. when towing a trailer or
when driving uphill or downhill).
▶ Snow chains are mounted.
▶ A wheel has been changed.
CAUTION
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light in the instrument cluster can be delayed or does
not light up at all.

The automatic distance 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 199.
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 199, 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 into “sharp” corners or in steep gradients / on steep inclines.
■
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.).
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 con-
nected trailer, the ACC becomes unavailable.
■
The control automatically cancels the engagement of the brake supportive
assistance systems (e.g. ESC) or when the maximum permitted engine speed is
exceeded.

214Driving
Fig. 259
Lane changes of other vehicles / stationary vehicles
Read and observe
on page 214 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. 258 -
. 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. 258 -
.
Other vehicles changing lanes
Vehicles that change onto the lane with a small distance » Fig. 259 -
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 vehi-
cle, » Fig. 259 -
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 214 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. 257 on page 216 .
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.
Malfunctions
Read and observe
on page 214 first.
If, for some unknown reason, ACC is not available, the warning light appears
in the display of the instrument cluster and an appropriate message is shown.
Sensor covered / dirty
If the sensor is dirty or covered, a message indicating that there is no sensor
view appears. Clean the sensor cover or remove the obstacles » Fig. 240 on
page 199 .
ACC not available
If the ACC is currently unavailable, a message concerning the unavailability ap-
pears. Stop the vehicle, switch off the engine and then start it again. If ACC
continues to be unavailable, seek the assistance of a specialist garage.
ACC fault
With an ACC fault, an error message appears. Seek help from a specialist ga-
rage.
218Driving
WARNINGThe general information relating to the use of assistance systems must be
observed » page 199, in section Introduction .
Note
■
The system component service life is monitored electronically. Further infor-
mation » page 35 , Safety systems .■
If the front passenger front airbag is deactivated, the belt tensioning func-
tion for the front passenger seat is switched off.
Operation
Read and observe
on page 224 first.
In critical driving situations (e.g. during emergency braking or a sudden changein direction), the following steps can be taken separately or combined in order
to reduce the risk of serious injury.
▶ The front passenger's and driver's seatbelts, if worn, are automatically ten-
sioned closely over the body.
▶ Opened door windows in the front doors are closed automatically up to a gap
of about 5 cm from the edge.
▶ The sliding/tilting roof is closed.
Once the critical driving situation has passed, the tension on the seatbelts will
be released again.
The system operates at two levels of protection.
The first level of protection
The system already intervenes in situations that may occur during dynamic
driving. As a result, this primarily helps to keep the driver and the passenger in
the correct seated position.
The first protection level can be deactivated in one of the following ways. ▶ in the menu
Infotainment
→
→
Driver assistance
.
▶ Deactivation of TCS » page 201.
▶ By selecting the driving mode
Sport
» page 223 .
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.

The lane departure warning (hereinafter known as system) helps to keep the
vehicle between the boundary lines of a lane.
The system recognises the boundary lines of the lane using a sensor
» Fig. 264 .
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■ The general information relating to the use of assistance systems must
be observed » page 199, 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.
224Driving
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.
