perchlorate. When the vehicle or parts of the
restraint system including a irbag modules
and safety belts with pretensioners are scrap·
ped, a ll applicable laws and regu lations must
be observed. Your a uthorized Audi dealer is
familiar with these requirements and we rec-
ommend that you have your dealer perform
this service for you .
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 tire-r im
comb inati ons not approved by Audi, lowering the
veh icle, chang ing the st iffness of the suspens ion,
including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l 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 wh ich it would not deploy if
the changes had not been made . Other kinds of
changes may reduce the fo rce levels measured by
the sensors and preven t the airbag from deploy-
ing when it should.
A
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 suspens ion components that
do not have the same performance charac-
teristics as the components originally instal-
led on your veh icle.
- Never use tire-rim combinations that have
not been approved by Audi.

A
WARNING
Items stored between the safety belt buckle
and the center console can cause the sensors
in the buckle to send the wrong information
to the electronic control modu le and prevent
the Advanced Airbag System from wo rking
properly.
- Always make sure that nothing can interfe re
with the safety belt buckles and that they
are not obstructed.
Knee airbags
Description of knee airbags

underneath the steer ing whee l ~ fig. 233, the

lower thigh areas and supplements the protec-
t ion prov ided by the safety be lts .
If the front airbags deploy, the knee airbags also
deploy in frontal collis ions when the deployment
threshold stored in the control unit is met

about front airbags.
