" N .... 0 0 \,;J ' A WARNING
A child in a rearward-facing child seat instal­
led on the front passenger seat will be seri ­
ously injured and can be killed if the front air­
bag inflates - even with an Advanced Airbag
System.
- The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the
backrest, center armrest, door or roof.
- Always install rear-facing child seats on the
rear seat.
- If you must install a rearward facing child
seat on the front passenger seat because of
exceptional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately install the rear­
facing child seat in a rear seating position and have the airbag system inspected by
your Audi dealer.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates .
- Never hold things in your hands or on your
lap when the vehicle is in use .
- Never transport items on or in the area of
the front passenger seat. Objects could
move into the area of the front airbags dur­
ing braking or other sudden maneuvers and
become dangerous projectiles that can
cause serious personal injury if the airbags
inflate.
- Never place or attach accessories or other
objects (such as cup holders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the steering wheel, instru­
ment panel, seat backrests or between
those areas and yourself. These objects could cause injury in a crash, especially
when the airbags inflate .
- Never recline the front passenger 's seat to
transport objects. Items can also move into
the area of the side airbag or the front air-
-
Airbag system
bag during braking or in a sudden maneu­
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined .
- Never place or transport objects on the
front passenger seat. Objects on the front passenger seat could cause the capacitive
sensor in the seat to signal to airbag system
that the seat is occupied by a person when it
in fact is not, or that the person on the seat
is heavier than he or she actually is. The
change in electric capacitance because of
such objects can cause the passenger front
airbag to be turned on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
worked without objects on the seat.
- Always make sure that there is nothing on the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occupied by a person when it is not , or to signal that it is occupied by some­
one who is heavier than the person actually
sitting on the seat. The presence of an ob­
ject could cause the passenger front airbag to be turned on when it should be off, or
could cause the airbag to work in a way that is different from the way it would have
worked without the object on the seat.
A WARNING ...__ -
The fine dust created when airbags deploy can
cause breathing problems for people with a history of asthma or other breathing condi­
tions .
- To reduce the risk of breathing problems,
those with asthma or other respiratory con­
ditions should get fresh air right away by
getting out of the vehicle or opening win­
dows or doors.
- If you are in a collision in which airbags de­
ploy, wash your hands and face with mild
soap and water before eating.
- Be careful not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue should get into your eyes,
flush them with water.

ligh t.
The Advanced Airbag System as well as the side
airbags and side curtain airbags with eject ion
mitigation features (including the e lectroni c con­
trol unit, sensors and system wiring) are all
monitored continuously to make sure that they
are funct ion ing prope rly whenever the ignition is
on . Every time you turn on the ignition, the air­
bag system indicator light
II (USA models) 1fll
(Canada models) will come on for a few seconds
(function check).
The system must be inspected when the
indicator light

(Canada models):
-does not come on w hen the ignition is switched
on,
-does not go out a few seconds after you have
switched on the ign ition, or
-comes on wh ile driving .
If an airbag system ma lf u nction is detected, the
ind icator light wi ll come on to serve as a constant
reminder to have the system inspected immedi­
ately.
If a malfunction occurs that turns the front air­
bag on the passenger side off, the
PASSENGER

A WARNING
- If the status of the Adv a need Airbag System
has changed while the vehicle is moving, the
PA SSENGER AIR BAG OFF light blinks for
156
about S seconds to catch the driver's atten­
tion. If this happens, always stop as soon as it is safe to do so and check the steps descri­
bed above .
- If the
PA SS EN GER 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 adu lt is properly seated and
restrained at one of the rear seating posi­
tions. Have the a irbag system inspected by
your author ized Audi dealer befo re trans­
porting anyone on the front passenger seat .
A WARNING
An airbag system that is not functioning prop­
erly cannot provide supplemental protection in a fronta l crash.
- If the airbag indicator light ¢
page 16
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 will not inflate when it should.
A WARNING
If the front a irbag inflates, a ch ild without a
chi ld restraint, or in a rea rwa rd-facing child
safety seat, or in a forward-fac ing ch ild re­
stra int that has not been prope rly insta lled
will be ser iously injured and can be killed.
- Even tho ugh you r vehicle is equipped with
an Advanced A irbag System, make certain
that a ll children, espec ia lly 12 years and
younger, always ride on the back seat prop­ erly rest rained for thei r age and size.
-Always install forward or rear -facing child
seats on the rear seat -even with an Ad­
vanced Airbag System.
- If you must install a rearward-facing child
seat on the front passenger seat because of
except ional circumstances and the

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

¢ page 152, More important things to know
about front airbags.
In addition to their normal safety function, safe­
ty belts help keep the driver or front passenger in position in a frontal collision so that the airbags
can provide supplemental protection.
The airbag system is not a substitute for your safety belt. Rather, it is part of the overall 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 134, Gener­
al information.
Remember too, airbags will deploy only once and
only in certain kinds of accidents -your safety
belts are always there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have already deployed, for
example when your vehicle strikes or is struck by
another after the first collision.
This is just one of the reasons why an airbag is
not a substitute for the safety belt. The airbag
system works most effectively when used with
the safety belts. Therefore , always wear your
safety belts correctly.
It is important to remember that while the sup­
plemental knee airbag system is designed to re­
duce the likelihood of serious injuries, other inju­
ries, for example, swelling, bruising and minor
abrasions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
- The electronic control module
- Two inflatable airbags (airbag and gas genera-
tor), one for the driver and one for the front
passenger
- The airbag indicator light in the instrument
panel
The knee airbag system will not deploy:
- when the ignition is switched off
Airbag system
- in frontal collisions when the deceleration
measured by the control unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warning/
indicator light is on)
¢ page 16 .
.&_ WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position
¢page 152.
- If the airbag indicator light ¢page 16
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.
How knee airbags work
App lies to: vehicles wi th knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags.
Fig. 156 Inflated airbags protecting in a fro ntal coll is ion
The knee airbag system has been designed so
that the airbags for the driver and front passen­
ger deploy in certain but not all frontal collisions .
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met .
When the system deploys, the airbags fill with a
propellant gas, and inflate between the lower
part of the instrument panel and the driver and
the lower part of the instrument panel and the
front
passenger ¢ page 152, fig. 153. .,.

Airbag system
~ WARNING
-Safety belts and the a irbag system will only
provide protection when occupants are in
the proper seating position
¢ page 162 .
-If the airbag indicator light¢ page 16
comes when the vehicle is being used, have
the system inspected immediate ly by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.
How supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained .
Fig. 158 Inflated side airbags on left side of veh icle , rear
side a irbag
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 provide this additional
protection, the side airbag must inflate within a
fraction of a second at very high speed and with
great force. The supplemental side airbag could
injure you if your seating position is not proper or
upright or if items are located in the area where
the supplemental side airbag expands. This ap­
plies especially to children
¢ page 166, Child
safety .
Supplemental side airbags inflate be­
tween the occupant and the door pane l on the
side of the vehicle that is struck in certain side
coll is ion ¢ fig. 158.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
162
help to reduce the risk of injury to the upper part
of the body.
A fine d ust may develop when the a irbag deploys.
This is norma l and does not mean the re is a fire
in the vehicle.
Important safety instructions on the side
airbag system
Airbags are only supplemental restraints. Always
properly wear safety belts and ride in a proper
seating position .
There is a lot that you and your passengers must
know and act according ly to help the safety belts
and airbags do their job to provide supplemental protection.
A WARNING
An inflating side airbag can cause serious or
fatal injury . Improperly wearing safety belts
and improper seating positions increase the
risk of serious personal injury 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 upright 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 trim panel in the
area where the supplemental side airbag inflates.
- Always make sure that safety belts are
worn correctly,
-Do not let anyone s itting in the front seat
put their hand or any other parts of their
body out of the window .
- 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 specifical ly approved by
Audi.
-Never use additional seat cushions that
cover the areas where the side airbags de-
ploy.

Airbag system
The s ide curtain airbag system supp lements the
safety belts and can he lp to reduce the risk of in­
jury for occupants' heads and upper to rso . The
side curtain airbag inflates in s ide impacts and
only when the veh icle acce leration registered by
the co ntro l unit is h igh eno ugh . If this rate is be ­
low the refe re n ce value programmed in to the
con trol unit, the s ide curta in a irbag will no t be
tr iggered, even though the ca r may be bad ly
d a mage d as a r esult of the collis io n.
It is not pos­
sib le to def ine an a irbag tr iggering range that
will cover every possib le ang le o f impact, since
the circumstances will 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.
