Airbag system
164
When are the airbags deployed?
The airbag system is designed in such a way that the driver airbag and the front
passenger airbag* are deployed in the event of a frontal collision of major severity.
In the case of a violent side crash , the side airbag* on the side of the car at which
the collision occurs, is deployed together with the head airbag*.
In certain accident situations it is possible that both the front as well as the side
airbags and the relevant head airbag are deployed at the same time.
The airbags are not deployed in the case of minor frontal and side collisions, in the
case of rear-end collisi ons and vehicle rollover.
Deployment factors
It is not possible to state globally which deployment conditions apply to the airbag
system in every situation as the circumstances which exist in the case of accidents
vary greatly. An important role in this case , for example, is played by factors such as
the type of object against which the vehicle impacts (hard, soft), the angle of impact,
the vehicle speed etc.
A decisive factor for the deployment of the airbags is the deceleration which occurs
during a collision. The control unit analyses the nature of the collision and activates
the relevant restraint system. If the vehicle deceleration which occurs and is meas-
ured during the collision remains below the prescribed reference values specified
in the control unit, the airbags are not deployed although the vehicle may well
suffer severe damage to the bodywork as a consequence of the accident.
The airbags are not deployed if:
•ignition off,
•a minor frontal collision,
•a minor side collision,
•a rear-end collision,
•rollover.
Note
•A grey white, non harmful gas is released when airbag is inflated. This is
perfectly normal and is not an indi cation of a fire in the vehicle.
•The dash panel must be replaced afte r the front passenger airbag has been
deployed.
•In the event of an accident in which the airbags are deployed:
− The interior lighting comes on (if the swit ch for the interior light is in the door
contact position),
− The hazard warning light is switched on,
− All the doors are unlocked,
− the fuel supply to the engine is interrupted.
