Fig. 75 Driver’s seat: belt positioner
Belt positioners make it easier to fasten the safe-
ty belts on the front seats.
The belt positioner extends automatically when
you close the door and switch the ignition on.
The belt positioner retracts automatically again
when the belt tongue locks into the belt latch, if
the safety belt is not fastened, if you switch the
ignition off, or if you open the door.

The belt positioners can cause injury or dam-
age if they pinch people or objects when ex-
tending or retracting.

Belt retractor lock
The safety belts on the rear seats and on the
front passenger seat are equipped with a belt re-
tractor lock.
> If you secure a child safety seat with a safety
belt, the belt retractor lock on the safety belt
may need to be activated. Follow the instruc-
tions from the child safety seat manufacturer.
> When a vehicle passenger has fastened a safety
belt, the belt retractor lock should not be acti-
vated. If the belt retractor lock has been acti-
vated unexpectedly, deactivate it.
Deactivating or activating the belt retractor lock
=> page 87.
Safety belt retractor
The safety belts are equipped with an automatic
belt retractor. This automatic retractor allows the
safety belt to be pulled all the way out when the
belt is pulled slowly. However, the automatic re-
tractor locks during sudden braking maneuvers.
It also locks the belts when accelerating, driving
uphill, and driving around curves.
Belt force limiter
Safety belts with belt force limiters reduce the
force placed on the body by the safety belts dur-
ing a collision.
Safety belt pretensioners
In certain driving situations, safety belts may be
tightened with reversible belt tensioners when
78
you start driving. If the safety belt is too loose, it
will be tightened so that the belt will rest closer
to the body.
In some collisions, pyrotechnic belt tensioners
may secure the safety belts so that they cannot
loosen. This reduces forward movement by the
vehicle passengers.

ZA WARNING
The pyrotechnic system can only provide pro-
tection during one collision. If the pyrotechnic
belt tensioners deploy, the pretensioning sys-
tem must be replaced by an authorized Audi

dealer or authorized Audi Service Facility.
@ Tips
Smoke may be released when pyrotechnic belt
tensioners deploy. This is not a sign of a vehi-
cle fire.
