Introduction to the restraint system
The restraint system can reduce the risk of
vehicle occupants coming into contact with
parts of the vehicle's interior in the event of
an accident. The restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system comprises:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing systems
The components of the restraint system work
in conjunction with each other. They can only
deploy their protective function if all vehicle
occupants always:
R fasten their seat belts correctly
(Y page 44)
R adjust their seat and head restraint prop-
erly (Y page 107).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the cor-
rect driver's seat position (Y page 106).
You also have to make sure that an airbag can inflate properly if deployed (Y page 46).
An airbag supplements a correctly fastened
seat belt. As an additional safety device, the
airbag increases the level of protection for
vehicle occupants in the event of an accident.
For example, if the protection of the seat belt is sufficient in an accident, the airbags are not
deployed. In the event of an accident, only the airbags that increase protection in the rele-
vant accident situation are deployed. How-
ever, seat belts and airbags generally do not
protect against objects penetrating the vehi-
cle from the outside.
Information on the restraint system operation
can be found under "Triggering of belt ten-
sioners and airbags" (Y page 55).40
