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-rim combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen-
sion struts, shock absorbers etc. can change
the forces that are measured by the a irbag
sensors and sent to the electronic control
un it. Some suspension changes can, 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 the 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 control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high-
er 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 airbag
will no t deploy at a seating position whe re 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-
tions can change Advanced Airbag per-
A irbag sys tem 17 1
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance
characteristics as the components origi-
nally installed on your vehicle.
- Never use tire-rim combinations 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 t he Advanced Air-
bag System from working properly.
- Always ma ke sure that nothing can inter-
fe re with the safety belt buckles and that
they are not obs t ruc t ed.
@ For the sake of the environment
Undeployed airbag modules and preten-
sione rs might be classified as Perc hlorate
Materia l -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/per-
ch lorate. When the vehicle or parts of the
restraint system including airbag modu les
safety be lts with pretensioners are scrap-
ped, a ll applicable laws and regulations
must be observed. Your authorized Audi
dealer is familiar with these requirements
and we recommend that you have your
dealer perform th is service for you.
