Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag System
pe rforms in a crash. For e xamp le, using t ire -r im
comb inations no t approved by Audi, lowering t he
veh icle, chang ing the stiffness o f the suspe nsio n,
i n cluding the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic contro l unit . Some suspens ion changes
can, for example, increase the force levels meas
ured by the sensors and make the airbag system
deploy in c rashes in w hich it would not deploy if
the changes had not been made. Other ki nds of
200
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy
i ng when it should .
_& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim comb inations can
change Advanced Airbag performance and in
crease the r isk of serious personal injury in a
crash .
- Never install suspension components that do not have the same performance charac
ter istics as the components origina lly instal
led on your vehicle.
- Never use tire-r im combinations that have
not been approved by Aud i.
