Audi A4 (B9) 2016-2022 Owner's Manual: Airbag system

General information



If you are transporting children in the vehicle, read the information and follow the safety precautions.

Safety system monitoring

The indicator light in the instrument cluster monitors the safety systems such as the airbags (including the control modules, sensor, and wiring) and the belt tensioners. It turns on when you switch the ignition on and turns off after several seconds.

If the indicator light does not turn on when the ignition is switched on, does not turn off after several seconds, or turns on or flashes while driving, there may be a malfunction in one of the safety systems. Drive to an authorized Audi dealer or authorized Audi Service Facility immediately to have the malfunction corrected.


Have the malfunction in the safety systems inspected immediately. Otherwise, there is a risk that the systems may not activate during an accident, which increases the risk of serious or fatal injury.


Sitting correctly and safely

The locations of the airbags are labeled with "AIRBAG". The following airbags are installed in your vehicle:

  1. Driver's airbag
  2. Front passenger's airbag
  3. Front side airbags and rear, if applicable
  4. Head curtain airbag with ejection mitigation
  5. Knee airbags

Airbags offer the best possible protection in your vehicle during an accident when they are used together with safety belts that are fastened correctly, and when passengers are sitting in the correct seating position. Airbags are a supplementary restraint system and do not replace safety belts.

Airbags may deploy during front-impact, side-impact, or rollover accidents.

The deployment area for the airbag system cannot be defined for every situation, since the circumstances surrounding accidents can vary widely.

Factors that play an important role include the Fig. 69 Airbag overview image (enlarged section: deployed airbags) condition of the object that the vehicle hits (hard or soft), the angle of impact, vehicle speed, etc.

The deciding factor for the deployment of the airbag system is the deceleration that occurs during an accident. Sensors in the vehicle are designed to detect the severity of an accident in conjunction with the control module, and to provide a targeted and timely deployment of the restraint system. If the vehicle deceleration that is measured during an accident is below the specified reference values in the control module, then the airbags will not deploy, even though the vehicle may be severely damaged from the accident. In these cases, the vehicle occupants will be protected by the safety belts if they are fastened and worn correctly.

The deployment of the front passenger's airbag will depend on the occupancy of the seat.

Each deployed airbag is filled with gas. When this occurs, the airbag covers open and the airbags unfold with great force into the deployment zone within milliseconds. Inflated airbags reduce the movement of passengers wearing safety belts in the direction of the impact and thus help to reduce the risk of injury. They can help to protect the head, upper body, and lap, for example. However, there is the possibility that airbag deployment can cause injuries.

The airbag system only works when the ignition is turned on.

If you or other vehicle passengers have physical limitations that prevent sitting in a correct position, modifications to the vehicle may be necessary.

For more information, contact an authorized Audi dealer or authorized Audi Service Facility, or call Audi customer support at 1-800-822-2834.


The side curtain airbags in your vehicle have ejection mitigation functions. This reduces the risk of being ejected from the vehicle interior during an accident, especially in the event of a vehicle rollover.
