-If the PASSENGER AIR BAG OFF light does
not go off when an adult who is not very
small 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 posi­
tions. Have the a irbag sys tem inspected by
your author ized Audi dealer befo re t rans­
porting anyone on the front passenger seat .
,8. WARNING
=
An airbag system that is not functioning prop-
erly cannot provide supplemental protection
in a fronta l crash .
-If the ai rbag ind icator light ~ page 29
comes when the vehicle is being used, have
the system inspected immediately by your
author ized Audi dealer. It is possib le that
the airbag will inflate when it is not sup­
posed to, or w ill not inflate when it should.
,8. WARNING
If the front a irbag inflates, a ch ild witho ut a
chi ld restraint, or in a rearward-facing child
safety seat, or in a forward-fac ing child re­
stra int that has not been properly insta lled
will be serious ly injured and can be killed.
-Even though you r vehicle is equipped with
a n Advan ced A irbag System, make certain
that all children, espec ially 12 years and
younger, always ride on the back seat prop­
erly restrained for the ir age and size.
-Always install forwa rd or re ar-facing child
safety seats on the rear seat -even with an
Advanced Airbag System.
-I f you must install a rearward-facing child
safety seat on the front passenger seat be ­
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
appear and stay on, immediately install the rear-facing chi ld safety seat in a rear seat ing
position and have the a irbag system in­
spected by your Audi dealer.
- If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenge r 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
PA SSEN GER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
,& WARNING
- If the PA SSENGER AIR BAG OFF light does
not go out when an ad ult is sitting on the
front passenger seat after taking the steps
described above, make sure the adu lt is
properly seated and restrained at one of the
rear seat ing 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 fronta l airbag on the passenger
side will be turned off, and the
P ASSE NGER
A IR BAG OFF light will stay on.
Repair , care and disposal of the airbags
Parts of the airbag system are installed at many
d ifferent places on your Aud i. Install ing, remov­
ing, servic ing or repa iring a part in an area of the
veh icle can damage a pa rt of an airbag system
and prevent that system from working properly
in a co llision.
There are some important things you have to
know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
environment .
,& WARNING
Improper care, servicing and repair proce­
dures can increase the r isk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly:
282
- 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 a irbag un its.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness 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, inst rument
panel, front seats or e lectr ica l system ( in­
cluding the instal lation of a udio eq uipment,
cellular telephones and CB radios, etc.)
m ust be performed by a qualified technician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we strong ly 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 specif ica lly approved by
A udi.
- Never use additional seat c ushions that
cover the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module mus t always be repai red immedi ­
ate ly by an authorized Audi dealer.
- The a irbag sys tem can deploy on ly once. Af­
ter an airbag has been deployed, it m ust be
replaced with new replacement parts de ­
signed and approved especia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be performed by qua lified workshops
only . Make sure that any airbag service

action is entered in your Audi Warranty &
Maintenance booklet under
AIRBAG RE­
PLACEMENT RECORD.
- Applies to plug-in hybrid* vehicles: In the
event of a co llision where the a irbags de­
ploy, the electrical connection to the high­
voltage battery is automatically disconnect­
ed. This prevents a short c ircuit.
@) For the sake of the environment
Undep loyed airbag modules and pretension­
ers might be classified as Perch lorate Materi­
al - special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­
rate. When the veh icle or parts of the re­
straint system incl uding airbag modules and
safety belts with pre tensioners 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 Sys tem
performs in a crash. For examp le, using tire-r im
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
electronic control unit . Some suspens ion 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 dep loy if
t he changes had no t been made. Other kinds of
changes may reduce the force levels meas ured by
the sensors and prevent the airbag from deploy­ ing when it should.
.&_ WARNING
Changing the vehicle 's s uspension incl uding
use of unapproved tire-rim combinations can
change Advanced A irbag performance and in-
Airb ag sys tem
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 originally instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbags
Applies to: vehicles wit h knee airbags
The knee airbag system con provide supplemen­
tal protection to properly restrained front seat
occupants.
F ig . 24 S Driver 's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering
whee l¢ fig. 245, the
airbag for the passenger is at about the same
height in the instrument pane l underneath the
glove compartment.
The knee airbag offers additiona l protection to
t h e driver's and passenger's knees and upper and
lower thigh areas a nd supplements the p rotec­
t io n prov ided by the safety belts .
If the front airbags deploy, the knee airbags also
deploy in frontal collis ions when the deployment
threshold stored in the control un it is met
¢ page 2 77, More important things to know
about front airbags .
In addition to their normal safety function, safe­
ty belts help keep the dr iver or front passenger in
pos it ion in a frontal collision so t hat the airbags
can p rovide supplemental protection .

Airbag syste m
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overa ll occu­
pant restraint system in your vehicle. Always re­ member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly . This is why you should
always wear your safety belt, not just because
the law requires you to do
so ¢ page 258, Gener­
al notes.
Remember too, airbags will deploy only once and
only in certain k inds of accidents
-your safety
be lts are always there to offer protection in those
accidents in wh ich airbags a re not supposed to
deploy or when they have already deployed, for
examp le when your vehicle str ikes or is struck by
another after the first collision .
This is just one of the reasons why an airbag is
not a substi tute for the safety belt. The a irbag
system works most effectively when used with
the safety belts. Therefore, a lways wear your
safety belts correct ly.
It is important to remember that whi le the sup­
p lemental knee a irbag system is des igned to re­
duce the like lihood of serious injuries, other inju ­
ries, for example, swe lling, bruising and minor
abrasions and friction burns can also occur when
an airbag inflates .
The kn ee airba g system bas ically consi sts of :
-The electronic control module
- T wo inflatab le airbags (airbag and gas genera-
t or), one for the driver and one for the front
passenger
- The airbag indicato r ligh t in the ins trument
pane l
The knee airbag system will not deploy:
-whe n the ignition is switched off
- in frontal collisions when the deceleration
measured by the control un it is too low
- in s ide collisions
- in rear -end collisions
- in rollovers
- in the event of a system ma lf u nction (wa rning/
indicator light is on)
¢ page 29 .

A WARNING
-Safety belts and the airbag system can only
provide protect ion when occupants are in
the proper seat ing pos ition
¢ page 2 77 .
- If the a irbag ind icator light ¢
page 29
comes when the veh icle is being used, have
the system inspected immediately by your
author ized Audi dealer.
It is possib le that
the airbag will inflate when i t is no t sup ­
posed to , or wi ll not inflate when it should.
How knee airbags work
Applies to: vehicles with knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags.
F ig . 246 Inflated a irbags protec ting in a fro nta l co llis io n
The knee airbag system has been designed so
that the airbags for the driver and front passen­
ger dep loy in certain but not all frontal collisions .
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the dep loyment
threshold stored in the control unit is met.
When the system deploys, the a irbags f ill with a
compressed propellant gas, and inf late between
the lower part of the instrument panel and the
driver and the lower part of the instrument panel
and the front
passenger¢ page 2 77, fig. 243 .
Althoug h they are not a soft p illow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the lower ex­
trem ities.
A ll of th is takes p lace in the blink of an eye, so
fast that many people don 't even realize that the
airbags have deployed. The airbags a lso inflate
with a great deal of force and it is important for

the risk of injury.
Important safety instructions on the knee
airbag system
A ppl ies to: ve hicles with knee a irbags
Airbags are only supplemental restraints. Always
wear safety belts correctly and ride in a proper
seating position.
There is a lot that you and your passengers must
know and do to help the safety belts and airbags
to provide supplemental protection .
A WARNING
An inflating knee airbag can cause ser ious in­
jury. Wearing safety belts incorrectly and im­
proper seating posit ions increase the r isk of
ser ious personal inj ury and death whenever a
vehicle is being used .
- The knee airbag system cannot protect you
prope rly if you are seated too close to any of
the a irbag lo cat ions. When ad justing thei r
seat positions, it is important that both the
dr iver and the front passenger keep their
upper bodies and knees at the following
min imum safe distances:
- at least 10 inches (25 cm) between the
chest and the steer ing wheel/ins trument
panel.
- at least 4 inches (10 cm) between the
knees a nd the lower pa rt of the instru­
ment panel.
- T he risk of persona l injury inc reases if you
lean forward or to the s ide, or if the sea t is
imp roperly posi tioned and you are not wear­
ing your safety belt . The risk increases even
more should the airbag deploy .
- Always make sure tha t the knee airbag can
inflate without interference. Objects be­
tween you and the airbag can increase the risk of inj ury in an accident by inter fer ing
-
Airb ag sys tem
with the way the airbag deploys or by being
pushed into yo u as the a irbag deploys.
- Neve r let anybody, especia lly children or
anima ls r ide in the footwell in front of the
passenger seat. If the airbag deploys, this
can result in serious or fatal i njuries.
- Neve r carry objects of any kind in the foot­
well a rea in front of the driver's or pas­
senger 's seat . Bulky objects (shopp ing
bags, for example) can i nterfere with or
prevent proper dep loyment of the airbag .
Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passengers.
- Make sure there are no cracks, deep scratch­
es or other damage in the area of the instru­
ment panel where the knee airbags are lo­
cated .
- If c hild ren are incorrectly seated, their risk
of injury increases in

The airbag system is monito red elect ronically to
make certa in that it is functioning properly at all
times. Each time you switch on the ign ition, the
airbag system indicator light will come on for a
few seconds (self diagnostics) .
The s ide a irba g system supplements the safety
be lts and can help to reduce the risk of injury to
the driver's, front and rear* passenger 's upper
torso on the side of the vehicle that is struck in a
side co llision . The airbag dep loys only in side im­
pacts and on ly when the vehicle acceleration reg­
istered by the control unit is h igh enough . If this
rate is below the reference value programmed in ­
to the control un it, the side airbags w ill not be
tr iggered , even though the car may be bad ly
damaged as a result of the collision.
It is not pos­
sib le to define an a irbag tr igger ing range that
will cover every possible ang le of impact , since
the circumstances wi ll vary considerably between
one co llision and another. Important factors in ­
clude, for example , the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc.

Fig. 249 Side impact protection: inf lated side a irbags
When the system is triggered, the airbag is filled
with propellant gas and breaks through a seam in
the seat surface area marked "AIRBAG" . It ex­
pands between the side trim panel and the pas­
senger. In order to help prov ide this add itional
protection, the side airbag must inflate within a
fract ion of a second at very high speed and with
great force. The supplemental side airbag cou ld

A WARNING
-
An inflat ing s ide a irbag can cause serious or
fatal injury. Improperly wearing safety belts and improper seating positions increase the
r isk of ser ious perso na l inju ry and death
whenever a vehicle is being used.
- In order to reduce the risk of injury when the supplemental side airbag inflates:
- Always s it in an upr ight position and never
lean against the area where the supple­
mental side airbag is located.
- Never let a child or anyone e lse rest their
head against the side tr im panel in the
area where the supplementa l side airbag
inflates.
- Always make sure that safety belts are
worn correctly,
- Do not let anyone sitting in the front seat put their hand or any other parts of their
body out of the w indow .
- Always make sure that the side airbag can
inflate w ithout interference.
- Never install seat covers or repla ceme nt
