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
Page 227 of 324

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.

The system is active and ready to intervene or is currently intervening.
Adaptive lane assist
Adaptive tracking helps to keep the vehicle in the position between the boun-
dary lines selected by the driver, by means of steering intervention.
If the position within the lane is changed, the system quickly adapts and holds
the newly-selected position.
Steering wheel vibrations
In the following situations, it may occasionally be the case that due to the
steering wheel vibrations, the system indicates that a driver steering interven-
tion is required. ▶ The system is not able to keep the vehicle by a within the lane due to a
steering intervention.
▶ During an intense system-related steering intervention, the system suddenly
cannot recognize the boundary lines.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
Read and observe
and on page 224 first.
The activation/deactivation of the system can be carried out in one of two
ways. ▶ In the instrument cluster display » page 47, Menu item

be observed » page 199, in section Introduction .■
Vertical traffic signs must always take precedence over the traffic signs
shown in the display. The driver is always responsible for correctly assess-
ing the traffic situation.
■
On the system side, only a traffic sign display is undertaken, neither a
warning when limit is exceeded or driving speed adjustment is undertaken!
■
Speed specifications in the displayed road signs refer to the customary
speed units. For example, the view
in the display can therefore refer to
km / h or mph, specific to the country.
WARNINGThe traffic signs may not be displayed or displayed incorrectly in the system
e.g. in the following situations.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
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.

up to date or whether the vehicle is currently in a location for which no naviga-
tion data are available.
Traffic signs unavailable
No speed restriction is detected, a message is displayed regarding the unavail-
ability of road signs.
Fatigue detection
The fatigue detection system (hereinafter referred to as system) recommends
the driver takes a break from driving when driver fatigue can be detected due
to the driver's steering behaviour.
From the starting of the journey, the system evaluates the steering behaviour
at speeds 65-200 km/h. If, while driving, there have been changes in the steer-
ing behaviours that are evaluated by the system as indicating possible fatigue,
a break recommendation is issued.
Conditions under which a break from driving is detected by the system ▶ The vehicle is stopped and the ignition is turned off.
▶ The vehicle is stopped, the seat belt is taken off and the driver's door is
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/deactivated in the Infotainment menu

WARNING■The general information relating to the use of assistance systems must
be observed » page 199, 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.
Tyre pressure monitoring
Introduction
This chapter contains information on the following subjects:
Storing the tyre pressure values and Infotainment display
229
The tyre pressure monitoring function (hereinafter referred to as the system)
monitors the tyre pressure while driving.
If the tyre inflation pressure changes, the warning light
lights up in the in-
strument cluster and an audible signal sounds » 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.
The tyre pressure values are always stored in the system if one of the fol-
lowing events occurs.
▶ Change of tyre inflation pressure.
▶ Change one or more wheels.
▶ Change in position of a wheel on the vehicle.
▶ The warning light
lights up in the instrument cluster.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 199, in section Introduction .■
Having the correct tyre inflation pressure is always the driver's responsi-
bility. Tyre inflation pressure must be checked regularly » page 261.
■
The system cannot warn in case of very rapid tyre inflation pressure loss,
e.g. in case of sudden tyre damage.
■
Before storing the pressure values, the tyres must be inflated to the
specified inflation pressure » page 261. If incorrect pressure values are
saved, the system may also not issue a warning even if the tyre inflation
pressure is too low.
CAUTION
To ensure proper system function, the tire pressure values must be stored ev-
ery 10 000 km or 1x a year.
