Front-End Crash

In the event of a front-end crash, a distinction is made between crash severity "light to medium collision" or "severe collision" (CS 3).

In the case of crash severity from light to medium collision (CS 1/CS 2), the driver's/front passenger's airbag are not triggered if it is detected that the occupants are wearing seatbelts.

If the occupants are not  wearing seatbelts, the driver's and front passenger's airbag would be triggered.

The seatbelt tensioners are triggered in all cases.

As of crash severity CS 2, the driver's/front passenger's airbag as well as the seatbelt tensioners are triggered. The safety battery terminal is activated, the electric fuel pump is switched off, and an emergency call is placed if a correspondingly prepared telephone is present in the vehicle.

In the US version, the knee airbags are also triggered.
