The forward movement of the body is cushioned when it makes contact with
the fully inflated airbag and the risk of injury to the remaining body parts is
thus reduced.
Front airbags - head and upper body. The airbags can be identified by the let-
tering featured on the steering wheel and on the dash panel on the pas-
senger side.
Driver's knee airbag - Legs. The airbag features the lettering on the
dashboard on the driver's side.
Side airbags - for the entire upper body (chest, stomach, pelvis) on the side
next to the door. The side air bags are marked by a label with the lettering
on the front seat backrests. The rear side airbags are provided with the letter-
ing in between the entrance area and the rear seat backrest.
Head airbags - head and neck. The airbags are provided with the lettering
marked on the B-pillar cladding.
Depending on the vehicle equipment, the airbag system consists of the
following parts.
▶
Individual airbags.
▶
Warning light
in the instrument
Key switch for the front passenger airbag
▶

The airbag system is only functional when the ignition is switched on.
When triggered, the airbag is filled with gas and unfolds. The inflation of the
airbag is carried out in a fraction of a second.
Upon inflation of the airbag, smoke is released. This is not an indication of a
fire in the vehicle.
Triggering conditions
It is not possible to generally determine which deployment conditions apply to
the airbag system in every situation. Important here is the hardness of the ob-
ject on which the vehicle impacts, the impact angle, the vehicle speed, etc.
The deceleration plays an important role in the deployment of the airbags. If
the vehicle deceleration which occurs and is measured during the collision re-
mains 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 following airbags will be deployed in the event of a severe frontal
collision.
Driver's front airbag.
▶
▶
Front passenger airbag.
▶
Driver's knee airbag.
The following airbags will be deployed in the event of a severe side
collision.
Front side airbag.
▶
Rear side airbag.
▶
▶
Head airbag.
When an airbag is deployed, the following events occur.
▶
The hazard warning lights are switched on.
All doors are unlocked.
▶
The fuel supply to the engine is interrupted.
▶
The interior light comes on (if the automatic operation of the interior light is
▶
switched on - switch ).
When there is no air bag deployment?
With minor frontal and side collisions, rear collision, overturning of the vehicle
or vehicle roll-over there is no airbag deployment.
