Introduction to the restraint system
The restraint system can reduce the risk of vehi-
cle 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 includes the:
R seat belt system
R airbags
R child restraint system
R child seat securing system The components of the restraint system work in
conjunction with each other. They can only offerprotection if all vehicle occupants always:
R have the seat belt correctly fastened
(Y page 44)
R have the seat and head restraint adjusted
properly (Y page 106)
As the driver, you must also make sure that the
steering wheel is also adjusted properly.
Observe the information on the correct driver's
seat position (Y page 106).
In addition, you must make sure that the airbags can inflate properly if they are deployed
(Y page 46).
An airbag supplements a correctly worn seat
belt. As an additional safety device, the airbag
increases the level of protection for vehicle
occupants in the event of an accident. The air-
bags are not deployed, for example, in the event
of an accident in which sufficient protection is
offered by the seat belt. In addition, only those
airbags, which in the applicable accident situa-
tions offer additional protection, are deployed in the event of an accident. However, the seat beltand airbag generally do not protect against
objects penetrating the vehicle from the out-
side.
Information on how the restraint system oper-
ates can be found under "Deployment of belt
tensioners and airbags" (Y page 53).
See "Children in the vehicle" for information on
children travelling with you in the vehicle as well
as on child restraint systems (Y page 56). Important safety notes

WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If it is necessary to adjust the vehicle to accom- modate a person with disabilities, contact a
qualified specialist workshop. Occupant safety
