WARNING (continued)
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi-
ately by an authorized Audi dealer.
The airbag system can be activated only once. After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the technical information, training
and special equipment necessary.
The airbag system can be deployed only once. After an airbag
has been deployed, it must be replaced with new replacement
parts designed and approved especially for your Audi model
version . Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only.
Make sure that any airbag service action is entered in your Audi
Warranty & Maintenance 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 circuit interrupter must only be
performed by a qualified dealer - risk of an accident!
- If the vehicle or the circuit interrupter is scrapped, all appli-
cable safety precautions must be followed.

For the sake of the environment
Undeployed airbag modules and pretensioners might be classified
as Perchlorate Material - special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlorate.
When the vehicle or
parts of the restraint system including airbag modules and safety
belts with pretensioners are scrapped, all applicable laws and regu-
lations must be observed. Your authorized Audi dealer is familiar
with these requirements and we recommend 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 performs in a crash. For example,
using tire -rim combinations
not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, including the
springs, suspension struts, shock absorbers etc. can change the
forces that are measured by the airbag sensors and sent to the elec-
tronic control unit. Some suspension changes can, for example,
increase the force levels measured 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 changes may reduce
the force levels measured by the sensors and prevent the airbag
from deploying when it should.
The sensors in the safety belt buckle for the driver and front
passenger seat tell the electronic control module if the safety belt is
latched or not. If the safety belt is being used, the front airbag will
deploy at a slightly higher rate of vehicle deceleration than if the
safety belt is not being used. Therefore, in a particular collision, it is
possible that an airbag will not deploy at a seating position where
the safety belt is being used but will inflate at the position where the
safety belt is not being used. It is important that nothing interfere
with the safety belt buckles so that the sensors can send the correct
information
about safety belt use to the electronic control unit.
&
WARNING
Changing the vehicle's suspension including use of unapproved
tire-rim combinations can change Advanced Airbag performance
and increase the risk of serious personal injury in a crash.
Never install suspension components that do not have the
same performance characteristics as the components originally
installed on your vehicle.
Never use tire-rim combinations that have not been approved
by Audi.
