The airbag is an integral part of the car s passive safety system.
In conjunction with the three-point seat belts, the airbag system gives the front occupants additional protection for the head and chest in the event of a severe frontal collision.
In a severe side collision the side airbags and the head-protection airbags reduce the risk of injury to the occupants
►.
In addition to their normal function of protecting the occupants in a collision, the seat belts also hold them in a position where the airbags can inflate properly and provide maximum protection.
The airbag system will only work with the ignition on. The airbag system is monitored electronically; the indicator lamp 
indicates whether the system is functioning properly.
indicates whether the system is functioning properly.The main parts of the airbag system are:
- The electronic monitoring system (control unit and sensors)
- The two front airbags
- The front side airbags, the side airbags in the outer rear seats*, (Sportback)
- The head-protection airbags*,
- The indicator lamp
in the instrument cluster
There is a fault in the airbag system if the warning lamp
- does not come on when the ignition is switched on.
- does not go out about 4 seconds after the ignition is switched on.
- goes out and then comes on again after the ignition is switched on.
- comes on or flickers while the car is moving.
- The airbags are not a substitute for the seat belts; they are an integral part of the car s overall passive safety system. The airbags can only offer effective protection if the occupants are wearing their seat belts. For this reason it is very important to wear the seat belts at all times link►.
- The seat belts and airbags can only provide maximum protection if the occupants are seated correctly link►.
- If you do not wear a seat belt, if you lean forward, or are not seated correctly while the vehicle is in motion, you are at greater risk of injury should the airbag system be triggered in an accident.
- Components of the airbag system are located in various parts of the vehicle. If repairs to other vehicle components make it necessary to perform work on the airbag system or to remove or install parts of the airbag system, this may cause damage to the airbag system. As a result, the airbags may not inflate correctly or may not be triggered at all in an accident situation. For this reason, you should always have the work carried out by a qualified workshop.
- If a fault should occur in the airbag system, have the system checked immediately by a qualified workshop. Otherwise the system may fail to trigger in an accident.
- Do not attempt to modify components of the airbag system in any way.
- Never make any alterations to the front bumper or the body.
- Do not remove the front seats.
- The airbag system can only be activated once; if the airbag has been triggered, the system must be replaced. Should the airbag system or airbag modules have to be replaced, the qualified workshop carrying out the replacement will document all details.
- If any repair work is required or the airbag and restraint systems have to be replaced, have the work carried out by your authorised Audi dealer or a qualified workshop which adheres to the Audi factory standards. This will minimise the risk of injury.
- If you sell the vehicle, remember to pass on the complete Service Wallet to the new owner. If any of the airbags have been deactivated, it is important that the new owner is also given the relevant documents.
- The relevant safety requirements must be observed when the vehicle or components of the airbag or belt tensioner systems are scrapped.
- For safety reasons, the alternator and the starter are both disconnected from the battery via a pyrotechnic circuit breaker in severe accidents.
- Any repairs to the pyrotechnic circuit breaker must always be performed by a qualified workshop – risk of accident!
- The relevant safety requirements must be observed when the vehicle or the circuit breaker are scrapped.
