is why you should always wear your safety belt, not just because th e
law requires you t o do so =>
page 159, "Genera l notes".
The safety belt buckle for the driver and front seat passenger have
switches that tell the airbag control module if the safety belt is
being used or not. If the safety belt is being used, the knee airbag
will deploy at a slightly higher rate of deceleration than if the belt is
not being used . Therefo re, in a particular col lision, it is possible that
an airbag will not deploy at a seating position where the safety belt
is being used but will inflate at the position where the safety belt is
not being used .
Remember too, airbags will deploy only once and only in certain
kinds of accidents - your safety belts are always there to offer
protection in those accidents in which airbags are not supposed to
deploy or when they have already dep loyed, for examp le when you r
vehic le strikes or is struck by another after the first collision.
This is just one of the reasons why an airbag is not a substitute for
the safety belt . The airbag system works most effectively when used
with the safety belts. Therefore, always wear your safety belts
correctly.
It is important to remember that while the supplemental airbag
system is designed to reduce t he likelihood of serious inj uries, other
injuries, for example, swelling, bruising, and minor abrasions can
also be associated with airbags.
The kn e e airbag syst e m bas ic ally c onsists of:
• The electronic control module
• Two inflatable airbags (airbag and gas generator), one for the
driver and one for t he front passenger
• The airbag indica t or light i n t he instrumen t panel
T h e kn e e airbag sy stem will not deplo y:
• whe n the igniti on is turned off
• in front -end collisions when the deceleration measured by the
control unit is too low
• in side coll isions
Safety first
Airb a g s yst e m
• in rear-end collisions
• in ro llovers
• in the event of a system malfunction (warning/indicator light illu -
minated)=>
page 20 .
& WARNING
• Safety belts and t he airbag system can only provide protection
when occupant s are in the proper seating position =>
page 177.
• If the airbag indicator light comes when the vehi cle is being
used, have the system inspected immediately by your authorized
Audi dealer . The airbag may not work properly when the vehicle
acceleration in a side collision is high enough to deploy the airbag.

The risk of injury to the leg area is reduced by fully
deployed knee air ba gs.

The knee airbag system has been designed so that the airbags for
the driver and front passenger are deployed in certain but not all
frontal collisions. ..,
