Airbag system


have not been specifically approved by Au-
di.
— Never use additional seat cushions that
cover the areas where the side airbags in-
flate.
— Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi-
ately by an authorized Audi dealer.
— The airbag system can deploy only once. Af-
ter
an airbag has been deployed, it must be
replaced with new replacement parts de-
signed and approved especially for your Audi
model version. Replacement of complete
airbag systems or airbag components must
be performed by qualified workshops only.
Make sure that any airbag service action is
entered in your Audi Warranty & Mainte-
nance booklet under AIRBAG REPLACEMENT
RECORD.
— For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit
interrupter.
— Work on the pyrotechnic circuit interrupter
must only be performed by a qualified
technicians who have the experience, in-
formation and special tools necessary to
perform the work safely.
— If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed.

Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension,
including the springs, suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit. Some suspension changes
can, for example, increase the force levels meas-
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
202
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy-
ing when it should.

Z\ WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in-
crease the risk of serious personal injury in a
crash.
— Never install suspension components that
do not have the same performance charac-
teristics as the components originally instal-
led on your vehicle.
— Never use tire-rim combinations that have
not been approved by Audi.

Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen-
tal protection to properly restrained front seat
occupants.

Fig. 161 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel > fig. 161, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec-
tion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment >
