For the sake of the environment
Undeployed airbag modu les and pretension-
ers might be classified as Perchlorate Materi-
al - special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo-
rate . When the vehicle or parts of the re-
straint system including airbag modules and
safety belts w ith pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa-
m ili ar with these requirements and we recom-
mend that you have your dealer perform this
service for you.
Other things that can affect Advanced
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-r im
comb inat ions not approved by Audi, lower ing the
vehicle, changing the stiffness of the suspension,
including the spr ings, 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 wh ich it would not deploy if
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 .
A
WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Air bag 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 insta l-
led on your vehicle.
- Never use tire-rim comb inations that have
not been approved by Audi.

Knee
airbags
Description of knee airbags
App li es to vehicles: with knee airbags
The knee airbag system can provide supplemen-
tal protection to properly restrained front seat
occupants.
Fig. 1 60 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering whee l
¢ fig. 160 ,
the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additiona l 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
threshold stored in the control unit is met
c>
page 151, More important things to know
about front airbags .
In addition to their normal safety function, safe-
ty belts help keep the dr iver or front passenger in
position in a frontal collision so that the airbags
can provide supplemental protection .
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall occu-
pant restraint system in your vehicle. Always re-
member that the airbag system can only help to
protect you if you are wear ing your safety belt
and wearing it properly. This is why you shou ld
always wear your safety belt, not just because
the law requires you to do so
