The system component service life is monitored electronically. Further infor-

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.
Lane Departure Warning (Lane Assist)

Malfunctions
226
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.

The system is active and ready to intervene.
The system intervenes when approaching the right-hand boundary lane.
Adaptive tracking takes place.
The system can intervene when the following basic conditions are present. The system is activated.
The vehicle is travelling at more than around 65 km/h.
The boundary line of at least one side of the lane is detected.
225Assist systems
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.

Check and refillFig. 293
Dipstick variants
Read and observe
and on page 255 first.
Check and refill oil under the following conditions. The vehicle is on a horizontal surface.
The engine operating temperature is reached.
The engine is turned off.
Checking the level
›
Wait a few minutes until the engine oil flows back into the oil trough.
›
Pull the dipstick out and wipe with a clean cloth.
›
Push the dipstick back to the stop and then pull it out again.
›
Read the oil level and push the dipstick back in.
The oil level must lie in range
A
» Fig. 293 . If the oil level is below range
A
, oil
must be added.
Refilling
›
Unscrew the cap of the engine oil filler opening
C
» Fig. 291 on page 254 .
›
Add oil of the correct specification in portions of 0.5 litres » page 255.
›
Check the oil level.
›
Screw the lid of the engine oil filler closed carefully.
CAUTION
■
The oil level must never be below range A » Fig. 293 there is a risk of dam-
age to the engine as well as to the exhaust system.■
If a top up with oil is not possible or the oil level is above range
A
,
stop
driving! Switch off the engine and seek assistance from a specialist garage.
NoteAn engine oil level which is too low is shown in the instrument cluster by the
warning light illuminating and also indicated by the message » page 38.
Nevertheless, we recommend checking the oil level on a regular basis using
the dipstick.
Coolant
Introduction
This chapter contains information on the following subjects:
Checking and refilling
257
The coolant helps to keep the engine temperature down, and consists of wa-
ter and coolant additive (with additives that protect the cooling system against
corrosion and prevent furring).
The proportion of coolant additive in the coolant must be 40 to 60 %.
The correct mix of water and coolant additive should be checked and if neces-
sary corrected by a specialist garage.
WARNING■ The following instructions must be followed at all times when working on
the engine compartment » page 252.■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurised - risk of scalding or
injury from splashes of coolant!
■
To protect against the coolant splashing, cover the cap with a cloth when
opening.
■
Coolant and coolant fumes are harmful - avoid contact with the coolant. If
the coolant comes into contact with the eye or skin, wash the affected area
with plenty of water for several minutes, and where appropriate seek medi-
cal help.
CAUTION
Do not cover the radiator and install any parts (e.g auxiliary lights.) in front of
the air intakes - There is a risk of the engine overheating.256General Maintenance
