The airbag system provides, as a supplement to the seat belts, additional oc-
cupant protection during severe frontal and side-on collisions.
The airbag will only provide optimum protection in conjunction with wearing
the seat belt, the airbag is not a substitute for the seat belts .
The functional status of the airbag system is indicated by the indicator light
in the instrument cluster » page 31.

Front airbags
Side airbags
Head airbags
ABCFront airbags - the forward thrust of the driver and of the front passenger is
cushioned when they make contact with the fully-inflated airbag, and the risk
of injury to head and chest is thus reduced.
The front airbags can be identified by the lettering
featured on the steer-
ing wheel and on the dash panel on the passenger side.
Side airbags - The load of the occupants is cushioned when plunged into the
fully inflated airbag. The risk of injury to the entire upper body (chest, stomach
and pelvis) is reduced on the side facing the door.
The side air bags can be identified by a label with the lettering
marked on
the front seat backrests.
Head airbags - The forward movement of the body is cushioned when it
makes contact with the fully inflated airbag, and the risk of injury to head and
chest is thus reduced.
The head airbags are provided with the lettering marked on the B-pillar
cladding.
Depending on the vehicle equipment, the airbag system consists of the
following parts. ▶ Individual airbags.
▶ Warning light in the instrument cluster
» page 31.
▶ Key switch for the front passenger airbag » page 19.
▶ Warning light for the front passenger airbag in the middle of the dash panel
» page 19 .16Safety
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 » Owner's Man-
ual Infotainment .
Pause recommendation
The icon appears and the following message for a few seconds in the display
of the instrument cluster and a message about the detected fatigue. An au-
dible signal is also emitted.WARNING■ The general information relating to the use of assistance systems must
be observed » page 100, 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
117
Storing the tyre pressure values and Infotainment display
118
Storing the tire pressure values using the key
118
The tyre pressure monitoring function (hereinafter known as "system") moni-
tors 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 32,
Tyre pressure .
The system can only function properly if the tyres have the prescribed tyre
pressure and this pressure values are stored in the system.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 100, in section Introduction .■
The correct tyre pressure values is always the driver's responsibility. The
tyre pressure should be checked regularly » page 146.
■
The system cannot warn in case of very rapid loss of tyre pressure, e.g. in
the event of a sudden puncture.
Storing the tyre pressure values
Read and observe
on page 117 first.
The tyre pressure valuesare always stored in the system, if one of the fol-lowing events is present.▶ Change of tyre pressure values.
▶ Change one or more wheels.
▶ Change in position of a wheel on the vehicle.
▶ The warning light in the instrument cluster.
The storage of the tyre pressure values depends on equipment, either in the
infotainment or by pressing a button.
WARNINGBefore storing the tyre pressures they must be inflated to the specified in-
flation pressure » page 146. If incorrect pressure values are storedthe sys-
tem may not warn even with a tyre pressure that is too low.
CAUTION
The tyre pressure values should be stored every 10 000 km or once a year to
ensure proper system function.117Assist systems

Once tyre inflation pressure of 2.0-2.5 bar has been reached, turn off the air
compressor. Maximum run time of 6 minutes » .

If you cannot reach an air pressure of 2.0 - 2.5 bar, unscrew the tyre inflation
hose

Drive the vehicle 10 metres forwards or backwards to allow the sealing agent
to “distribute” in the tyre.

the driver's field of view.
At a tyre inflation pressure of 2.0–2.5 bar, the journey can be continued at a maximum speed of 80 km/h or 50 mph.
WARNING■ If the tire does not inflate at least. 2.0 bar, the damage is too great. The
sealing agent cannot be used to seal the tyre. Stop driving! Seek help
from a specialist garage.■
The tyre inflation hose and air compressor may get hot while the tyre is
being inflated – there is a risk of injury.
CAUTION
Switch off the air compressor if it has been running for as much as 6 minutes –
risk of damage to the compressor! Allow the air compressor to cool a few mi-
nutes before switching it on again.
Information on driving with repaired tyres
Read and observe
on page 154 first.
The filling pressure of the repaired tyre is a 10-minute test drive.
If the tyre pressure is 1.3 bar or less
›
You cannot properly seal the tyre using the breakdown kit.
Do not contin-
ue to drive! Seek help from a specialist garage.
If the tyre pressure is 1.3 bar or more›Set the tyre pressure back to the correct value » page 146.›
Continue driving carefully to the nearest specialist garage at a maximum
speed of 80 km/h (50 mph).
WARNINGA tyre filled with sealant has the same driving characteristics as a standard
tyre. The following guidelines must therefore be observed.■
Do not drive faster than 80 km/h (50 mph).
■
Avoid accelerating at full throttle, sharp braking and fast cornering.
Jump-starting
Introduction
This chapter contains information on the following subjects:
Jump-starting using the battery from another vehicle
157WARNING■ The following instructions must be followed at all times when working on
the engine compartment » page 137.■
When handling the vehicle battery, the following warnings must be ob-
served » page 142 .
■
A discharged vehicle battery can freeze at temperatures just below 0 °C.
If the battery is frozen, do not carry out a jump start with the battery of an-
other vehicle – risk of explosion and injury!
■
Never jump-start vehicle batteries with an electrolyte level that is too low
– risk of explosion and caustic burns!
