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 t ire-rim
comb inations no t approved by Audi, lowering t he
veh icle, chang ing the stiffness of the suspe nsio n,
including 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 crashes in which it would not deploy if
the changes had not been made. Other kinds of
164
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy-
ing 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 risk 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 Audi.
