Airb ag syst em
entered in your Audi Warranty & Mainte­
nance booklet under
AIRBAG REPLACEMENT
RECORD.
- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit interrupter .
- Work on the pyrotechnic circ uit inter rupt­
er must only be performed by a qualified
technicians w ho have the experience, in­
formation and special tools necessary to perform the work safely.
- If the veh icle or the circuit interrupter is
scrapped, a ll applicable safety precautions
must be followed.
@ For the sake of the environment
Undep loyed airbag modu les and pretension ­
ers might be classified as Perchlorate Materia l
- specia l hand ling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­ rate. W hen the veh icle or parts of the re­
straint system including a irbag modules and
safety belts with prete nsioners are scrapped ,
all applicable laws and regulat ions must be
observed. Your authorized A udi dealer is fa­
m iliar with the se requirements a nd we recom­
mend that you have your dealer perform this
service for yo u.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system ca n
change the way that the Advanced A irbag System
performs in a crash. For example, using t ire- rim
combinat ions not approved by Audi, lower ing the
ve hicl e, chang ing the stiffness of the suspension,
includ ing the spr ings, suspension s truts, shoc k
absorbers etc. can change the forces that are
measured by the a irbag sensors and sent to the
e lectronic control unit. Some suspension changes
can, for example, increase the force levels meas ­
ured by the sensors and make the a irbag system
deploy in c rashes in which it wou ld not deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
164
the sensors and p revent the airbag from dep loy ­
ing when it shou ld .
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 suspension components that
do not have the same performance charac­
ter istics as the components origina lly instal­
led on you r vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
