If the system detects a risk of collision, the symbol
» Fig. 208 appears in the
display and you will hear an acoustic signal.
At the same time, the braking system is prepared for possible emergency brak- ing.
The pre-warning display can occur in the following situations.
▶ If there is a risk of collision with a moving obstacle in a driving speed range of
about 30 km/h to about 210 km/h.
▶ There is a risk of a collision with a stationary moving obstacle in a vehicle
speed range of approximately 30 km/h to about 85 km/h.
With a warning the brake pedal must be pressed or the moving obstacle is to
be 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 assist
If the driver brakes inadequate with an impending collision, the system auto-
matically increases braking force.
The braking assistance only occurs as long as the brake pedal is being firmly
pressed 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 steering intervention.

Adaptive Chassis Control (DCC)
Read and observe
on page 171 first.
The adaptive chassis control (following known as DCC) provides the ability toadjust the shock characteristics for the sporty, normal or comfortable driving
when the corresponding control mode is selected.
The DCC evaluates steering response and road conditions while driving contin-
uously and adjusts the suspension behaviour within the selected driving mode
accordingly.

Function
Read and observe
on page 174 first.
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 protection level can be deactivated in one of the following ways.
▶ The system deactivation in the Infotainment » Owner´s Manual Infotain-
ment , chapter CAR - vehicle settings .
▶ Deactivation of TCS » page 143, Braking and stabilisation systems .
▶ Selecting the driving mode
Sport
» page 171 .
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 in
panic braking at high speeds.
This level of protection cannot be deactivated.
Vehicles with the Front Assist system
On vehicles with Front Assist the system has been expanded to include infor-
mation from the radar sensor » page 143. Using this information a system in-
tervention may also occur when there is the danger of a collision with an ob-
stacle detected in front of the vehicle.
A system intervention can only take place on the basis of the information col-
lected by the radar sensor, if the radar sensor is fully functional.
Note
If the front passenger front airbag is deactivated » page 19 the belt tensioning
function for the front passenger seat is switched off.

The lane departure warning (following known as system) helps to keep the ve-
hicle between the boundary lines of a lane.
The system detects the boundary lines of a lane using the camera » Fig. 211.
174Driving
The system can intervene when the following basic conditions are present.The system is activated.
The vehicle is travelling at more than about 65 km/h 1)
.
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 system function may be restricted if, for example there is danger due
to ruts on a downhill road or in a crosswind.Activation / deactivation

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 time at which the warning light indicates a vehicle in the “blind spot” » Fig. 215 is dependent on the speed difference between the two vehicles. The
larger the speed difference, the earlier the warning is given by means of the
indicator light.
Two warning levels

illuminated .
▶ A vehicle was detected in the “blind spot”.
The warning light is
flashing .
▶ A vehicle was detected in the “blind spot” and the flashing light is on.
An advanced warning for vehicles with Lane Assist
The warning light flashes
even if the steering wheel is “turned” in direction
of the vehicle in the blind spot. Therefore the Lane Assist » page 174 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.

Information messages
182
The fatigue detection system (following known as system) recommends the
driver taking a break from driving when, because of the driver's steering be-
haviour, driver fatigue can be detected.
WARNING■ Please take note of the general points relating to the use of assistance
systems » page 142, in section Introduction .■
For the driving ability is always the driver's responsibility. Never drive if
you feel tired.
■
The system may not detect all cases where a break is needed.
■
Therefore, take regular, sufficient breaks during long trips.
■
There will be no system warning during the so-called micro-sleep.
Note■ In some situations, the system may evaluate the driving incorrectly and thus
mistakenly recommend a break (e.g. sporty driving, adverse weather condi-
tions or poor road conditions).■
The system is designed primarily for use on motorways.
Function
Read and observe
on page 182 first.
From the start of the journey, the system evaluates steering behaviour. If,
while driving, there have been changes in the steering behaviours that are
evaluated by the system as indicating possible fatigue, a break recommenda-
tion is issued.
The system evaluates steering behaviour and recommends a break at speeds
of 65-200 km / h.
The system detects a break from driving when one of the following condi-
tions is met.
▶ The vehicle is stopped and the ignition switched off.
▶ The vehicle is stopped, the seat belt removed and the driver's door opened.
▶ The vehicle is stopped for more than 15 minutes.
If none of these conditions are met or if the driving style is not changed, the
system recommends a driving break again after 15 minutes.
The system can be activated or deactivated in the Infotainment » Owner´s
Manual Infotainment , chapter CAR - vehicle settings .

The tyre pressure monitoring function (following known as system) monitors
the tyre pressure while driving.
When changing the tyre inflation pressure, the warning light illuminates
in
the instrument cluster and an audible signal is heard.
Information on the procedure for the notification of change of tyre inflation
pressure » page 35 .
The system can only function properly if the tyres have the prescribed inflation
pressure and these pressure values are stored in the system.
WARNING■ Please take note of the general points relating to the use of assistance
systems » page 142, in section Introduction .■
Having the correct tyre inflation pressure is always the driver's responsi-
bility. Tyre pressure should be checked regularly » page 217.
