Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of vehi-cle occupants coming into contact with parts ofthe vehicle's interior in the event of an accident.The restraint system can also reduce the forcesto which vehicle occupants are subjected duringan accident.
The restraint system comprises:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securing systems
The components of the restraint system work inconjunction with each other. They can onlydeploy their protective function if, at all times, allvehicle occupants:
Rhave fastened their seat belts correctly(Ypage 43)
Rhave the seat and head restraint adjustedproperly (Ypage 91)
As the driver, you also have to make sure thatthe steering wheel is adjusted correctly.Observe the information relating to the correctdriver's seat position (Ypage 91).
You also have to make sure that an air bag caninflate properly if deployed (Ypage 45).
An air bag supplements a correctly worn seatbelt. As an additional safety device, the air bagincreases the level of protection for vehicleoccupants in the event of an accident. For exam-ple, if, in the event of an accident, the protectionoffered by the seat belt is sufficient, the air bagsare not deployed. When an accident occurs, onlythe air bags that increase protection in that par-ticular accident situation are deployed. How-ever, seat belts and air bags generally do notprotect against objects penetrating the vehiclefrom the outside.
Information on restraint system operation canbe found under "Triggering of the EmergencyTensioning Devices and air bags" (Ypage 52).
See "Children in the vehicle" for information onchildren traveling with you in the vehicle as wellas on child restraint systems (Ypage 54).
Important safety notes
GWARNING

cause it to no longer work as intended. The

fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
