Airbag
sy s tem
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys-
tem performs in a crash. For example, using
tire-r im combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the sp rings, suspen-
sion struts, shock absorbe rs etc. can change
the forces that are measured by the a irbag
sensors a nd sent to the electron ic control
un it. Some suspension changes ca n, for exam-
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not dep loy if the
changes had not been made . Other kinds of
changes may reduce the force levels meas-
ured by t he sensors and prevent the airbag
from deploying when it should .
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec-
tronic con t rol module if the safety belt is
latched or not . If the safety belt is being used,
the front a irbag will deploy at a slightly high-
e r rate of vehicle deceleration than if the safe-
ty belt is not being used. Therefo re, in a par-
ticular collision, it is poss ible that an a irbag
will not deploy at a seati ng position where the
safety be lt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen-
sors can send the correct information about
safety belt use to the electron ic control unit .
A
WARNING
Changing the vehicle 's suspension includ-
ing use of unapproved tire-rim combina-
t ions can change Advanced Airbag per-
formance and increase the risk of ser ious
personal inju ry in a crash.
- Never install suspens io n components
that do not have the same performance
characteristics as the components origi -
nally installed on your vehicle .
- Never use tire -rim combinat ions that
have not been approved by Audi.
A
WARNING
-
Items stored between the safety be lt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the e lectronic con-
trol module and prevent the Advanced Air-
bag System from working properly.
- Always ma ke sure that nothing can inter-
fere wit h the safety belt buckles a nd that
they are not obstruc t ed .

For the sake of the environment
Undeployed airbag modules and preten-
s ione rs might be classified as Perchlorate
Materia l - specia l hand ling may apply, see
www.dt sc.ca.gov/hazardouswaste/per-
ch lorate. When the vehicle or parts of t he
restraint system including airbag modu les
and safety belts with pretensioners are
scrapped, all applicab le laws and regu la-
tions must be observed. Your authorized
Audi dealer is familia r with these require-
ments and we recommend that you have
your dealer perform this service fo r you.
