Technical Data
When are the airbags deployed?The airbag system is designed in such a way that the driver 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* in the front seat and the head
airbag* on the side on which the collision occurs are deployed.
It is also possible under certain special accident situations that the front as well as
the side airbags and head airbags* 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 collisions 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 is switched off;
•
a minor frontal collision;
•
a minor side collision;
•
a rear-end collision;
•
Rollover of the vehicle.Note
•
A grey white or red, non harmful gas is released when airbag is inflated. This is
perfectly normal and is not an indication of a fire in the vehicle.
•
In the event of an accident in which the airbags are deployed:
−the interior lighting comes on (if the switch for the interior light is in the door
contact position),
−the hazard warning light is switched on;
−All the doors are unlocked.
