Basic illustration
X Adjust the seat (Y page 101).
The seat backrest must be in an almost ver-
tical position.
X Pull the seat belt smoothly out of seat belt
guide =and engage belt tongue ;into belt
buckle :.
The seat belt on the driver's seat and the
front-passenger seat may be tightened auto-
matically; see "Belt adjustment"
(Y page 43).
X If necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.
Releasing the seat belts !
Make sure that the seat belt is fully rolled up.
Otherwise, the seat belt or belt tongue will be
trapped in the door or in the seat mechanism. This could damage the door, the door trim
panel and the seat belt. Damaged seat belts
can no longer fulfil their protective function
and must be replaced. Visit a qualified spe-
cialist workshop.
X Press release button in belt buckle, hold belt
tongue firmly and guide the seat belt back.
Seat belt adjustment The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. This func-
tion adjusts the driver's and front-passenger
seat belt to the upper body of the occupants. The belt strap is tightened slightly when:
R the seat belt tongue is engaged in the belt
buckle and
R the ignition is switched on
The seat-belt adjustment will apply a certain
tightening force if any slack is detected between
the vehicle occupant and the seat belt. Do not
hold on to the seat belt tightly while it is adjust-
ing.
You can switch the seat-belt adjustment on and
off in the on-board computer (Y page 212).
Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster reminds you that all vehicle occu-
pants must fasten their seat belts. It may light up continuously or flash. A warning tone may also
sound.
The 7 seat belt warning lamp goes out and
the warning tone stops as soon as the driver's
and the co-driver's seat belts have been fas-
tened. Airbags
Introduction The airbag installation location is identified by
the label AIRBAG.
An airbag supplements a correctly fastened seat
belt. It is not a substitute for seat belts. The air- bag provides additional protection in the corre-
sponding accident situations.
Not all airbags are deployed in an accident. The
various airbag systems work independently of
one another (Y page 51).
However, no system available today can com-
pletely eliminate injuries and fatalities.
Due to the required speed of the airbag after
deployment, it is also not possible to entirely
rule out the risk of injuries caused by the airbag.

When adjusting a seat, you or another vehicle occupant could become trapped by the guiderail of the seat, for instance. There is a risk of
injury.
Make sure that no one has any part of their
body within the sweep of the seat when

The head restraints cannot provide the inten-
ded protection unless they are fitted and
adjusted correctly. There is an increased risk of injury to the head and neck in the event of
an accident or sudden braking, for example.
Always drive with the head restraints fitted.
Ensure that the centre of the head restraints
support the back of each vehicle occupant's
head at eye level before driving off. G

see the "Interior care" section.
R do not transport heavy loads on the seats.
Do not place sharp objects on the seat
cushions, e.g. knives, nails or tools. The
seats should only be occupied by passen-
gers, if possible.

not cover the seats with insulating materi-
als, e.g. blankets, coats, bags, seat covers,
child seats or booster seats.
