You should therefore always fasten the seat belts, not only because this
is required by law, but also for safety reasons and for your own protection

Caution
The dash panel must be replaced after the front passenger airbag has
been deployed.
Function of the front airbags
Risk of injury to the head and chest area is reduced by fully
inflated airbags.
The airbag system is designed in such a way that the driver and front
passenger airbag* are deployed in the event of a frontal collision of major
severity.
Using the system Safety
In certain accident situations both the front airbags as well as the head
and side airbags may be deployed together.
If the airbags are deployed, the airbags are filled with a propellant gas and
inflated in front of the driver and front passenger
inflate in fractions of a second and at a high speed in order to be able to
offer that additional protection in the event of an accident. The forward
movement of the driver and of the front passenger is cushioned when they
make contact with the fully inflated airbag and the risk of injury to head and
chest is thus reduced.
The specially developed airbag allows the gas to flow out of the inflated
airbag in a controlled manner (depending on the load of the particular car
occupant) in order to cushion head and chest areas. The airbag then
deflates subsequently to such an extent, after an accident, to again
provide a clear view forward.
A grey white, non harmful gas is released when airbag is inflated. This is
perfectly normal and is not an indication of a fire in the vehicle.
The airbag develops enormous forces when triggered, which can lead to
injuries if the sitting position or seated position is not correct ⇒
