Introduction to the restraint system
The restraint system can reduce the risk of
vehicle occupants comin gintoc ontact with
parts of the vehicle' sinterior in the even tof
an accident. The restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system includes the:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securin gsystem
The components of the restraint system work
in conjunction with each other .They can only
offer protection if all vehicle occupants
always:
R have the seat belt correctly fastened
(Y page 47)
R have the seat and head restraint adjusted
properly (Y page 123)
As the driver, you must also make sure that
the steering wheel is also adjusted properly.
Observ ethe information on the correct driv-
er's seat position (Y page 122).
In addition ,you must make sure that the air-
bags can inflat eproperly if they are deployed
(Y page 50).
An airbag supplement sacorrectly worn seat
belt. As an additional safet ydevice, the airbag
increases the level of protection for vehicle
occupants in the even tofanaccident. The
airbags are not deployed, for example, in the even tofana ccidentinwhich sufficient pro-
tection is offered by the seat belt. In addition,
only thos eairbags, which in the applicable
acciden tsituation soffer additional protec-
tion ,are deployed in the even tofanaccident.
However ,the seat belt and airbag generally
do not protect against objects penetrating
the vehicle from the outside.
Information on how the restraint system
operates can be found under "Deploymen tof
belt tensioner sand airbags" (Y page 53).44

indicator immediately (Y page 299).Airbags
Introduction The installation location of an airbag is iden-
tified by the AIRBA Gsymbol.
An airbag supplements acorrectly worn seat
belt. It is not areplacemen tfor the seat belt.
The airbag offers additional protection in
applicable accident situations.
Not all airbags are deployed in an accident.
The differen tairbag systems work independ-
ently of each other (Y page 53).
However, no system available today can com- pletely eliminate injuries and fatalities.
It is also not possible to completely rule out a
risk of injury caused by an airbag due to the
speed at which the airbag must be deployed.
Important safet ynotes G
WARNING
If you deviat efromt he correc tseat position,
the airbag cannot perform its intended pro-
tectiv efunction and can even cause addi-
tional injuries when deployed. There is an
increased risk of serious or even fatal injuries.
In order to avoid such risks, always ensure
that all vehicle occupants:
R fasten their seatbelts correctly, including
pregnant women
R are seate dcorrectly and maintain the fur-
thest possible distanc efromt he airbags

Always ensure that there are no object sloca-
ted betwee nthe airbag and the vehicle occu-
pant.
R Adjust the seats properly befor ebeginning
your journey. Always make sure that the
seat is in an almost upright position. The centr
eofthe head restraint must support
the head at about eye level.
R Move the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
drive nsafely.
R Only hold the steerin gwheel on the out-
side. This allows the airbag to be fully
deployed.
R Always lean against the backrest while driv-
ing. Do not lean forwards or lean against

Immediately replace an integrated child seat
or ICS padded play table that has been modi- fied, damaged or subjected to aheavy load as
the result of an accident. Only use the ICS
padded play table with its original cover or
with acover that has been approved by the
manufacturer, and do not used aprotective

direct sunlight or heat, parts could heat up.
Children could suffer burns on these parts,
particularly on metallic parts. There is arisk of
injury.
If you and your child leave the vehicle, cover
the ICS padded play table so that it is not
exposed to direct sunlight and heat. If the ICS padded play table has been exposed to direct sunlight, allow it to cool before securing a
child to it. Never leave children unattended in
the vehicle.
Observe the notes on the ICS paddedp lay
