Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
comb inations not approved by Audi, lower ing the
vehicle, chang ing the stiffness of the suspension,
including the springs, suspension struts , shock
absorb ers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic 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 which it would not deploy if
the changes had not been made. Other kinds of
158
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 combinations 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-
teristics as the components origina lly instal-
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
