One or more airbag systems are triggered in severe collisions, depending on the circumstances.
The airbag system is not triggered in minor collisions or in rear collisions. In these situations, the occupants are protected by wearing the seat belts.
Factors determining the triggering response
It is not possible to define the exact triggering response of the airbag system in all possible situations, since the circumstances in different types of accident will vary considerably. Important factors include, for example, the nature (hard or soft) of the object which the car hits, the angle of impact, Audi Q7 speed and so on.
Whether the airbags are triggered depends primarily on the Audi Q7 deceleration rate resulting from the collision. By processing the signals from the sensors located in the Audi Q7, the electronic control unit is immediately able to evaluate the severity of the collision and activate the restraint systems accordingly. If the deceleration rate is below the predefined reference value in the control unit the airbags will not be triggered, even though the accident may cause extensive damage to the car.
Note
The airbag may release a fine dust when it inflates. This is quite normal and does not mean there is a fire in the Audi Q7.
