" N .... 0 0 \,;J ' -If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger seat, always move the
seat into its rearmost position in the seat's
fore and aft adjustment range, as far away
from the airbag as possible. The backrest must be adjusted to an upright position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
A WARNING
- If the PASSENGER AIR BAG OFF light does
not go out when an adult is sitting on the
front passenger seat after taking the steps
described above, make sure the adult is
properly seated and restrained at one of the
rear seating positions.
- Have the airbag system inspected by your
Audi dealer before transporting anyone on
the front passenger seat .
(D Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenger
side will be turned off, and the
PASSENGER
AIR BAG OFF
light will stay on.
Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi . Installing , remov­
ing , servicing or repairing a part in an area of the
vehicle can damage a part of an airbag system
and prevent that system from working properly
in a collision.
There are some important things you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing an airbag from de-

Airbag system
ploying when needed or deploying an airbag
unexpectedly :
- Never cover, obstruct, or change the steer­
ing wheel horn pad or airbag cover or the in­
strument panel or modify them in any way.
- Never attach any objects such as cup holders
or telephone mountings to the surfaces cov­
ering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened with plain water . Solvents or cleaners
could damage the airbag cover or change
the stiffness or strength of the material so
that the airbag cannot deploy and protect properly.
- Never repair, adjust, or change any parts of
the airbag system.
-All work on the steering wheel, instrument
panel, front seats or electrical system (in­
cluding the installation of audio equipment,
cellular telephones and CB radios, etc.)
must be performed by a qualified technician
who has the training and special equipment
necessary.
- For any work on the airbag system, we
strongly recommend that you see your au­
thorized Audi dealer or qualified workshop.
- Never modify the front bumper or parts of
the vehicle body.
- Always make sure that the side airbag can inflate without interference:
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi .
- Never use additional seat cushions that
cover the areas where the side airbags in­
flate.
- 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 deploy only once. Af­
ter an airbag has been deployed, it must be
replaced with new replacement parts de­
signed and approved especially for your
Audi model version. Replacement of com­ plete airbag systems or airbag components
157

Airbag system
must be performed by qualified workshops
only. Make sure that any airbag service ac­
tion is entered in your Audi Warranty
&
Maintenance booklet under AIRBAG RE·
PLACEMENT RECORD .
-For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
technicians who have the experience, in­
formation and special tools necessary to
perform the work safely.
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed .
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al
-special handling may apply , see
www .dtsc.ca.gov/hazardouswaste/perchlo ­
rate . When the vehicle or parts of the re­
straint system including airbag modules and
safety belts w ith pretensioners are scrapped,
all applicable laws and regulations must be
observed . Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend 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
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
i ng 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 Aud i.
Knee airbags
Description of knee airbags
Applies to: vehicles with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig . 155 Driver 's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel ¢
fig. 155, the
airbag for the passenger is at about the same height in the instrument panel underneath the
glove compartment.
The knee airbag offers add itional protect ion to
the driver's and passenger's knees and upper and lower thigh areas and supplements the protec­
tion prov ided by the safety belts .
If the front airbags deploy, the knee airbags also
deploy in frontal coll is ions when the deployment
