For the sake of the environment
Undep loyed 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 regu lations must be
observed. Your authorized Audi dealer is fa-
m iliar 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
cha nge the way that the Advanced Airbag System
pe rforms in a crash. For example, using tire-r im
comb inat ions not approved by Audi, lower ing the
veh icle, chang ing the stiffness of the suspens ion,
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 suspens ion 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 preven t 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 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 insta l-
led on your veh icle .
- Never use tire-rim comb inations that have
not been approved by Audi.

A
WARNING
Items stored between the safety belt buckle
and the center console can cause the sensors
in the buckle to send the wrong information
to the electronic contro l module and prevent
the Advanced Airbag System from wo rking
properly.
- Always make sure that noth ing can inte rfe re
w ith the safety belt buckles and that they
are not obst ructed.
Knee

Description of knee airbags
The knee airbag system can provide supplemen-

The knee airbag offers add itiona l protection to
the d river's and passenge r's knees and uppe r and
