is why you should alw ays wear your safety belt, not just because the
law requires you to do so =>
page 209, "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 . Therefore, in a par ticular collision, it is possib le 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 off er
protection in those accidents in wh ich airbags are not supposed to
deploy or when they have already deployed, for examp le when you r
vehic le strikes or is struc k by another after the first collision.
This is just one of the reasons why an airbag is not a subs tit ut e 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 the like lihood of serious injuries, other
injuries, for example, swelling, bruising, and minor abrasions can
also be associated with airbags.
The kn e e airbag system bas ically consists of:
• The electro nic control module
• Two inflatable airbags (airbag and gas generato r), one for the
driver and one for the front passenger
• The airbag indicator light in the instrument panel
Th e kn e e airbag system will not deploy :
• whe n the ignit io n is turned off
• in front -end collisions when the deceleration measured by the
control uni t is too low
• in side collisions
Airb a g syst e m
• in rear-end co llisions
• in ro ll overs
• in the event of a system malfunction (warning/indicator light illu -
m inated)=>
page 19.
& WARNING
• Safety belts and the airbag system can only provide protecti on
when occupants are in the proper seating position
=> page 227 .
• If the airbag indicator light comes when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer . The airbag may not work properl y when the vehicle
acceleration in a side collision is high enough to deploy the airbag.

The knee airbag system has been designed so that the airbags for
t he drive r and front passenger are deployed in certain but not all
frontal col lisions.
