For the sake of the env ironment
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 veh icle or parts of the re-
straint system including airbag modules safe-
ty belts with pretensioners
are scrapped, all
app licable laws and regulations must be ob-
served. Your authorized Audi dealer is familiar
w ith these req uirements and we recommend
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
pe rforms in a crash. For examp le, using tire-r im
comb inat ions not approved by Audi, lowering the
veh icle, chang ing the stiffness of the suspens ion,
including the springs, suspension struts, shock
absorbers etc
.
can change the forces that are
measured by the airbag sensors and sent to the
e lectronic 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 fo rce 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 Airbag performance and in-
crease the risk of serious personal injury in a
crash.
- Never install suspens ion components that
do not have the same performance charac-
teristics as the components
or iginally instal-
led on your veh icle.
-
Never use tire-rim combinations that have
not been approved by Audi.
