in the display of the instrument cluster may lead to serious personal injury
or damage to the vehicle.■
If you have to stop for technical reasons, then park the vehicle at a safe
distance from the traffic, switch off the engine and activate the hazard
warning light system » page 77. The warning triangle must be set up at
the prescribed distance - observe the national legal provisions when doing
so.
■
The engine compartment of your car is a hazardous area. While working in
the engine compartment, be sure to observe the following warn-
ings » page 192 , Engine compartment .
1)
Applies to vehicles with START-STOP system.
34Using the system
WARNINGWhen a fault in the airbag system occurs, there is a risk of the system not
being triggered in the event of an accident. Therefore, this must be
checked immediately by a specialized garage.
Tyre pressure
Read and observe
on page 34 first.
The warning light lights up
If the warning light illuminates while driving, this means that one of the
tyres has undergone a pressure change.
An audible signal sounds as a warning signal.
›
Immediately reduce speed and avoid sudden steering and braking manoeu-
vres.
›
Stop the vehicle, turn the ignition off and check the tyres and their inflation
pressure » page 204 .
›
Correct the tyre pressure if necessary or replace the affected
wheel » page 214 or use the repair kit » page 218.
›
Store the tyre pressure values in the system » page 167.
The indicator light flashes for about 1 min. and then remains lit
If the warning light flashes for approximately 1 minute and then 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.
Seek help from a specialist garage.
The illumination of the warning light can have the following reasons.
› The vehicle is loaded on one side. Distribute loads as evenly as possible.
› 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.
Store the tyre pressure values in the system » page 167.
CAUTIONUnder 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.
Note
If the vehicle's battery has been disconnected and reconnected, the warning
light comes on after switching on the ignition. If the warning light does not
go out after moving a short distance, this means there is an error in the sys-
tem. Seek help from a specialist garage.
Brake linings
Read and observe
on page 34 first.
If the indicator light
is illuminated , the brake pads are worn.
The following message is shown in the information cluster display. Check brake wear!

51Information system
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
NoteThe system component service life is monitored electronically. Further infor-
mation » page 38 , Security systems .
Function
Read and observe
on page 161 first.
The system is activated whenever the ignition is switched on, and is ready tointervene automatically under the following conditions.
The engine is running.
The vehicle moves at a speed of more than 30 km/h.
In critical driving situations (e.g. during emergency braking or a sudden change
in 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.
› The windows in the side doors (if open) are automatically closed 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 level of protection can be deactivated by one of the following meas-
ures.
› Deactivation of the system in Infotainment
» Operating instructions for Info-
tainment , chapter Vehicle settings (CAR button) .
› Deactivation of TCS
» page 139.
› Selecting the driving mode Sport
» page 160.
Provided that the driving mode Sports 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 in
panic braking at high speeds.
This level of protection cannot be deactivated.
Note
If the front passenger front airbag is deactivated » page 21 the belt tensioning
function for the front passenger seat is switched off.

Lane Assist (From here on referred to only as the system), helps to keep the
vehicle within the lane.
The system detects the boundary lines of a lane using the camera » Fig. 159.
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 overridden at any
time.
162Driving
WARNING■The system only serves to support and does not relieve the driver of the
responsibility for the vehicle operation.■
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 on the road may be incorrectly detected as lines. As a re-
sult, an incorrect steering intervention may take place.
WARNINGThe detection capability of the camera may be limited by various external
influences. In such cases, the assistant may not detect the line between
two lanes at all or not properly. The detection capability of the camera may
be restricted in the following situations, for example.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When driving around “sharp” bends.
■
The camera is blinded by the sun.
■
The camera is blinded by the oncoming traffic.
■
The viewing range of the camera is impeded by a vehicle traveling ahead.
■
The camera viewing range is obstructed by an obstacle.
CAUTION
Do not attach any stickers or similar objects to the windscreen to avoid impair-
ing the functions of the Assist 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.

The system intervenes when approaching the right-hand boundary lane.
Adaptive lane assist ensues (boundary lines on both sides of the vehicle
detected).
The system can intervene when the following basic conditions are present. The system is activated.
The vehicle is travelling at more than 65 km/h.
ABCD163Assist systems
The boundary lines are clearly visible (appropriate longitudinal markings).
The boundary line of at least one side of the lane is detected.
The driver's hands are on the steering wheel.
The lane is more than 2.5 m in width.
If the turn signal is switched on prior to driving over the boundary line (e.g.
when making a turn), no steering intervention takes place when the vehicle
approaches the boundary line. The system regards the situation as an inten-
ded lane change.
Warning lights in the instrument clusterWarning lightMeaningThe system is active, but not ready to intervene.The system is active and ready to intervene or is currently
intervening.
Adaptive lane assist
Adaptive lane assist helps to keep the vehicle in the position between the
boundary lines selected by the driver, by means of steering intervention.
If the system detects only one boundary line, it will help to maintain the selec-
ted proximity from said boundary line.
If the proximity to the detected boundary line is changed, the system quickly
adapts and maintains the newly-selected position.
WARNINGThe function of adaptive lane guidance Assist system may be restricted
when driving e.g. over rutted roads, on a slope, or if there are lateral winds.
Activating/deactivating
Read and observe
and on page 163 first.
The activation or deactivation of the system can be carried out in one of two
ways.
