Your vehicle is equipped with an "Advanced
Airbag System " in compliance with Un ited
States Federa l Motor Veh icle Safety Standard
(FMVSS) 208 as applicable at the time you r
vehicle was manufactured . The safety belts
for the seats have "pretensioners" that help to take slack out of the belt system. The pre­
ten sioners are also act ivated by the electronic
control unit for the airbag system.
T he front safety belts also have load lim iters
to help reduce the forces applied to the body
in a crash.

detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature.
Please be sure to heed the WARNINGS -they
are ex tremely important for your safety and
the safety of your passengers, especially in ­
fants and small children .
A WARNING
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only supplemental protection .
- Airbag work most effectively when used
with properly worn safety belts .
- Therefore, always wear your safety belts
and make sure that everybody in your ve ­
hicle is properly restrained .
- Always hold the steering wheel with both
hands on the outside of the steering
wheel rim at the 9:00 o'clock and 3:00
o'clock positions to help reduce the risk
of personal injury if the driver's airbag in­
flates.
- Never hold the steering wheel at the 12
o'clock position or with your hands any­
where inside the steering wheel or on the
steering wheel hub. Holding the steering
wheel the wrong way increases the risk of severe injury to the arms, hands, and
head if the driver airbag deploys .
A WARNING
Objects between you and the airbag will
increase the risk of injury in a crash by in­
terfering with the way the airbag unfolds
and/or by being pushed into you as the air­
bag inflates.
- Always make sure nothing is in the front
airbag deployment zone that could be
struck by the airbag when it inflates.
- Objects in the zone of a deploying airbag
can become projectiles when the airbag
deploys and cause serious personal in­
jury.
- Never hold things in your hands or on
your lap when the vehicle is in use .
-
Airbag system 151
-Never place accessories or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or bulky) on the
doors; never attach then to the doors or
the windshield; never place them over or
near or attach them to the area marked
,,AIRBAG " on the steering wheel, instru­
ment panel or the seat backrests; never
place them between these areas and you
or any other person in the vehicle.
- Never attach objects to the windshield
above the passenger front airbag, such
as accessory GPS navigation units or mu­
sic players. Such objects could cause seri­
ous injury in a collision, especially when
the airbags inflate.
- Never recline the front passenger seat to transport objects. Items can also move
into the deployment area of the side air ­
bags or the front airbag during breaking
or in a sudden maneuver . Objects near
the airbags can fly dangerously through
the passenger compartment and cause
injury, particularly when the seat is re­
clined and the airbags inflate.
A WARNING
-=
A person on the front passenger seat , es-
pecially infants and small children, will re­
ceive serious injuries and can even be kil­
led by being too close to the airbag when
it inflates.
- Although the Advanced Airbag System in your vehicle is designed to turn
off the
front passenger airbag if an infant or a
small child is on the front passenger
seat, nobody can absolutely guarantee
that deployment under these special conditions is impossible in all conceiva­
ble situations that may happen during
the useful life of your vehicle.
- The Advanced Airbag System can deploy
in accordance with the ,,low risk" option
for 3-and 6-year-old children under the

Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was manufactured.
The front Advanced Airbag System supple­ ments the safety belts to provide addit ional
protection for the driver's and front passeng­
er's heads and upper bodies in frontal crashes .
The airbags inflate only in frontal impacts
when the vehicle dece le rat io n is high enoug h.
The front Advanced Airbag System for the
fro nt seat occupants is not a substitute for
your safety belts . Rather, it is part of the over­
a ll occupa nt restraint system in your veh icle.
A lways remember that the airbag system ca n
on ly help to pro tect you, if you are s itting up ­
right, wearing yo ur safety belt and wearing it
properly. This is why you and yo ur passengers
must always be properly restrained, not just
beca use the law requires you to be.
The Advanced Airbag System in your veh icle
has been certified to meet the " low risk" re­
qu irements for 3 and 6 year-o ld children on
the passenger side and very small adu lts on
the dr iver side. The low risk deployment crite­
ria are intended to he lp reduce the risk of in­
jury through interaction with the front airbag that can occur, for example, by being too
close to the steering wheel and instr ument
panel when the airbag inflates .
In add ition, the system has been cer tified to
comply with the "s uppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months o ld and younger
who are restrained on the front passenger
seat in child restraints that are listed in the
Standard
c> page 171, Child restraints and
Advanced front airbag system .
"Suppression" requires the front a irbag on the
passenger side to be turned off if:
- a child up to abo ut one year of age is re­
strained on the front passenger seat in one
of the rear-fac ing or forward-facing infant
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad ­
vanced A irbag System in your veh icle was
cert ified . Fo r a listing of the chi ld restraints

Advanced Airbag System components
The front passenger seat in your vehicle has a
l o t of very important pa rts of the Advanced
A irbag System in it. These parts incl ude the
capacitive passenger detect ion sys tem, wir­
ing, brac kets, and more . The cont ro l unit
monitors the system on the front passenger
seat when the ign ition is switched on and
turns the airbag indicator light on w hen a
malfunction i n the one of the system compo­
n ents is detected
c::;, page 159 . Because the
front passenge r seat contains important pa rts
of the Advanced Airbag System, you must
take ca re to pr even t it from be ing damaged.
Damage to the seat may preven t the Ad ­
vanced A irbag System for the front passenger
seat from doing its job in a crash .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front o f the veh icle that
measure ve hicle acceleration/dece leration
to provide information to the Advanced Air­ bag System abo ut the severity of the crash .
- An electronic co ntro l unit, with i ntegrated
c rash sensors for f ront and side impacts.
The cont ro l unit "decides" whether to fire t
he front a irbags based on the in format ion
received from the crash sensors. The contro l
un it also "decides" whether the sa fety belt
pretens ioners sho uld be activated.
- An Advanced Airbag with gas generator fo r
the dr iver inside the steering wheel hub.
- An Advanced Airbag with gas gene rator in­
side the inst rument panel for the front pas­
senger.
- A capacit ive passenger detection system un­
derneath the front passenger seat cover.
This system measures the electrical capac i­
tance of the person in the seat. The informa­
tion registered is se nt cont inuous ly to the
elect ronic control un it to regu late deploy­
ment of the front Advanced A irbag on the
passe nger side.
- An airbag monitor ing system and indicator
light in t he i nstr ument cluster

t he ele ct ron ic cont ro l unit to regula te de­
p loyment of the front Adv a need Ai rbags.
- The
PASSENGER AIR BAG OFF ligh t comes

- if the ignition is switched off when a crash
occurs,
- in side collisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measured by
the a irbag system is less than the m inimum
threshold needed for airbag deployment as
registered by the electronic control unit.
The f ront pas seng er airbag al so will n ot
deploy:
- when the front passenger seat is not occu­

A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the r isk of injury when the air­

must always sit in an upright posit ion,
must not lean against or place any part
of the ir body too close to the area where
the a irbags are located.

- The inflating airbag will hit the ch ild 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-fac ing ch ild seats on
the rear seat.
- If you must install a rearward fac ing

A WARNING
r---------
O b j e cts between you and the airbag will
increase the risk of injury in a crash by in­
terfering 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 veh icle 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 air­ bags during braking or other sudden ma­
neuvers and become dangerous projec­
tiles that can cause ser ious personal in­

Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, 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 dis­
carded components do not cause injury or pol­ lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened 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 de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including 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
authorized Audi dealer or qualified work­
shop. -
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 replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can deploy 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. Replace­
ment of complete airbag systems or air­
bag components must be performed by
qualified workshops only . Make sure that
any airbag service action is entered in
your Audi Warranty
& Maintenance book­
let under
AIRBAG REPLACEMENT RE­
CORD.
- For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­ nic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified technicians who have the ex­ perience, information and special tools
necessary to perform the work safely.
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@) For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate

www.dtsc.ca.gov/hazardouswaste/per­chlorate. When the vehicle or parts of the
restraint system includ ing airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dealer is familiar with these require­
ments and we recommend that you have
your dealer perform this serv ice 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 example, using
tire-r im combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag sensors and sent to the electron ic control
unit. Some suspension changes can, for exam­
ple, 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 meas­
ured by the sensors and prevent the airbag
from deploying when it should .
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance 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 origi­
nally insta lled on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.

Knee airbags
Description of knee airbags
Applies to vehicles: wi th knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.

The dr iver knee airbag is in the instrument
panel underneath the steering wheel
¢
fig. 144, the airbag for the passenger is at
about the same height in the instrument pan­
el underneath the glove compartment.
The knee airbag offers additional protection
to the driver's and passenger's knees and up ­
per and lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags
also dep loy in frontal collisions when the de­
ployment threshold stored in the control unit
is met¢
page 156, More important things to
know about front airbags.
In addition to their normal safety function,
safety belts help keep the driver or front pas­
senger in position in a frontal collision so that
the airbags can provide supplemental protec­
tion.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the airbag system can
only help to protect you if you are wearing
your safety be lt and wearing it properly. This
is why you should always wear your safety
belt, not just because the law requires you to
do so
