Audi Q5: Belt tensioners
How safety belt pretensioners work
In front, side and rear-end collisions above a particular severity and in a rollover, safety belts are tensioned automatically.
The safety belts are equipped with safety belt pretensioners. The system is activated by sensors in front, side and rear-end collisions of great severity and in a rollover. This tightens the belt and takes up belt slack. Taking up the slack helps to reduce forward occupant movement during a collision.
Note
Never let the belt remain over a rear seatback that has been folded forward.
Tips
The safety belt pretensioner can only be activated once.
- In minor frontal and side collisions, in rear-end collisions and in accidents involving very little impact force, the safety belt pretensioner are not activated.
- When the safety belt pretensioners are activated, a fine dust is released. This is normal and is not caused by a fire in the vehicle.
- The relevant safety requirements must be observed when the vehicle or components of the system are scrapped. An authorized Audi dealer or qualified workshop is familiar with these regulations and will be pleased to pass on the information to you.
- Be sure to observe all safety, environmental and other regulations if the vehicle or individual parts of the system, particularly the safety belt or airbag, are to be disposed. We recommend you have your authorized Audi dealer perform this service for you.
Service and disposal of safety belt pretensioner
The safety belt pretensioners are parts of the safety belts on your Audi. Installing, removing, servicing or repairing of belt pretensioners can damage the safety belt system and prevent it from working correctly in a collision.
There are some important things you have to know to make sure that the effectiveness of the system will not be impaired and that discarded components do not cause injury or pollute the environment.
WARNING
Improper care, servicing and repair procedures can increase the risk of personal injury and death by preventing a safety belt pretensioner from activating when needed or activating it unexpectedly:
- The belt pretensioner system can be activated only once. If belt pretensioners have been activated, the system must be replaced.
- Never repair, adjust, or change any parts of the safety belt system.
- Safety belt systems including safety belt pretensioners cannot be repaired. Special procedures are required for removal, installation and disposal of this system.
- For any work on the safety belt system, we strongly recommend that you see your authorized Audi dealer or qualified technician who has an Audi approved repair manual, training and special equipment necessary.
