wheel, instrument panel, windshield, or what­
ever else is in the way
c::> fig. 153. This imp act
with the vehicle interior has all the energy
t hey had just before the crash.
Never rely on a irbags alone for protection.
Even when they deploy, airbags provide only
additional protection. Airbags are not sup­
posed to deploy in all kinds of accidents. Al­
though your Audi is equipped with airbags, all
vehicle occupants, including the driver , must
wear safety belts correctly in order to mini­
mize the risk of severe injury or death in a
crash.
Remember too, that airbags will deploy only
once and that 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 . Unbelted
occupants can also be thrown out of the vehi­
cle where even more severe or fatal injuries
can occur.
It is also important for the rear passengers to
wear safety belts correctly. Unbelted passen­
gers in the rear seats endanger not only them­
selves but also the driver and othe r passen­
gers ~
fig. 154. In a frontal collision they will
be thrown forward violently, where they can
hit and injure the driver and/or front seat pas­
senger .
Safety belts protect
People think it's possible to use the hands to
brace the body in a minor collision . It's simply
not true !

Safety belts used properly can make a big dif­
ference. Safety belts help to keep passengers
in their seats, gradually reduce energy levels
applied to the body in an accident, and help
prevent the uncontrolled movement tha t can
cause serious injuries . In addition, safety belts
reduce the danger of being thrown out of the
vehicle .
Safety belts attach passengers to the car and
give them the benefit of being slowed down
more gently or "softly" through the "give" in
the safety belts, crush zones and other safety
features engineered into today's vehicles. By
"absorbing " the kinetic energy over a longer
period of ti me, the safety belts make the
forces on the body more "tolerable" and less
likely to cause injury.
Although these examples are based on a fron­
tal collision, safety belts can also substantial­
ly reduce the r isk of injury in other kinds of
crashes. So, whether you're on a long trip or
just going to the corner store, always buckle up and make sure others do, too. Accident sta­
tistics show that vehicle occupants properly
wearing safety belts have a lower risk of being
injured and a much better chance of surviving
an accident. Properly using safety belts also
greatly increases the ability of the supplemen­
tal airbags to do their job in a collision . For
this reason, wearing a safety belt is legally re­
quired in most countries including much of
the United States and Canada.
Although your Audi is equipped with airbags,
you still have to wear the safety belts provid­
ed. Front airbags , for example, are activated
only in some frontal collisions. The front air­
bags are not activated in all frontal collisions,
in side and rear collisions, in roll overs or in
cases where there is no t enough decelera tion
through impact to the front of the vehicle .
The same goes for the other airbag systems in
your Audi . So, always wear your safety belt
and make sure everybody in your vehicle is
properly restrained!

Airbag system Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints . For
airbags to do their job , occupants must al­
ways properly wear their safety belts and be
in a proper seating position.
F or your safety and the safety of your passen­
gers, before driving off, always:
"" Adjust the driver's seat and steering wheel
properly ¢
page 129,
"" Adjust the front passenger's seat properly
¢ page 54,
""Wear safety be lts properly r::::> page 141,
""Always properly use the proper child re-
stra int to protect ch ildren
r::::> page 173.
In a collision, airbags must inflate within the
blink of an eye and with considerable force .
The supplementa l airbags can cause injuries if
the dr iver or the front seat passenger is not
seated prope rly . T herefore in order to help the
a irbag to do its job, it is impo rtant, both as a
d river and as a passenge r to s it properly at all
times.
By keep ing room between your body and the
steer ing whee l and the front of the passenge r
compartment, the airbag can i nflate fully and
comp lete ly and provide supp lemen tal protec­
tion in ce rtain frontal collisions

There is a lot that the d river and the passen­
ge rs ca n and must do to help the individua l
safety features ins talled in your A ud i work to­
gether as a system.
P rope r seat ing pos ition is important so that
the front airbag on the dr iver s ide ca n do its
job. If yo u have a physical impa irment or con-
A irbag system 147
dition that prevents yo u from sitting properly
o n the driver seat with the safety belt properly
f astened and reach ing the peda ls, or if you
have concerns with regard to the function or
operation o f the Advanced Airbag System,
please contact your author ized Audi dealer or
qualified wo rkshop, o r call Audi Customer Re­
l ations at 1-800-822-2834 fo r poss ible modi­
fica tions to your veh icle.
When the airbag system dep loys, a gas gener ­
ator will fill t he a irbags, break open the pad­
ded cove rs, and inflate between the steer ing
whee l and the dr ive r and between the instru­
ment pane l and the fron t passenger. The a ir­
bags will deflate immedia tely after dep loy­
ment so that the front occupants can see
thro ugh the windshie ld again witho ut inter­
ruption .
A ll of th is takes place in t he blink o f an eye, so
f ast that many people don't even realize that
the airbags have deployed. The airbags a lso
inflate with a great dea l of force and nothing
shou ld be in their way when they deploy.
Front a irbags in combination with properly
wor n safety belts slow down and lim it the oc ­
c u pant's fo rward movement . Togethe r they
help to preve nt the drive r and front seat pas­
senger from h itti ng pa rts of the inside of the
vehicle while reducing the forces act ing on the
occupant dur ing the crash . In this way they
help to reduce the risk of injury to the head
and upper body in the crash. Airbags do not
protect the arms or the lower parts o f the
body.
Both front airbags wi ll not inflate in all fronta l
collisions . The trigge ring of the airbag system
depends on the vehicle dece lerat ion rate
ca used by the co llision and registered by the
elec tron ic control unit. If t his rate is below
the reference value programmed into the con ­
tro l unit, the airbags will not b e trigge red,
even t hough the car may be bad ly damaged as
a res ult of the co llision . Ve hicl e damage, re­
pair costs or even the lack of ve hicle damage
is not necessarily an indica tion of whether an
airbag shou ld inflate or not . .,. •

148 Airbag sys tem
Since the cir cumstances will vary considerab ly
between one collision and anot her, it is not
possib le to def ine a range of vehicle speeds
that will cover every possible k ind and angle
of impact t hat will always trigger the a irbags.
Important factors include, for example, the
nature (hard or soft) of the object which the
car h its , the ang le of impact, vehicle speed ,
etc. The front airbags will also not inflate in
side or rea r collisions, or in ro ll-overs .
Always remember : Airbags will deploy only
once, and only in certa in k inds of co llisions .
Your safety belts are always there to offer pro­
tection in those s ituations in which airbags
a re not supposed to deploy, or when they have
a lready deployed ; for example , when your ve­
hicle strikes or is struck by another vehicle af­
te r the first co llision .
This is jus t one of the reasons why an a irbag is
a supplementary restra int and is not a substi­
tute fo r a safety belt . The airbag system
works most effect ively when used with the
safety belts. There fore, always properly wear
your safety belts¢
page 138.
A WARNING
Sitting too close to the steer ing whee l or
instrument panel will dec rease the effec­
t iveness of the airbags and will increase
the risk of personal injury in a collision .
- Never sit closer than 10 inches (2S cm)
to the stee ring wheel or instrument pan­
el.
- If you cannot sit more than 10 inches
( 2 5 cm) from the s teer ing whee l, investi­
gate whethe r adap tive equipmen t may
be available to help you reach the pedals
and increase your seating distance from
the steering wheel.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way, your risk of in jury is much higher.
- You will also receive serio us injuries and
cou ld even be killed if you are up against
the airbag or too close to it when it in­
flates - even with an Advanced Airbag. -
To reduce the risk of injury when an a ir­
bag inflates, always wear safety be lts
properly ¢
page 141, Safety belts.
-Always make certain that ch ildren age 12
or younger always ride in the rear seat. If
children are not properly restrained, they
may be severe ly injured or killed when an
ai rbag inflates .
- Never let children ride unrestrained or
improperly restrained in the vehicle. Ad ­
just the front seats prope rly .
- Never ride with the back rest reclined .
- Always sit as far as possible from the
steer ing whee l or the instrument pane l
¢page 129.
-Always sit upright with your back against
the backrest of your seat .
- Never p lace your feet on the instrument
panel or on the seat. Always keep both
feet on the floor in front of the seat to
help prevent serio us in ju ries to the legs
and h ips if the airbag inflates.
- Never recline the front passenger 's seat
to transport objects , Items can a lso
move into the a rea of the s ide airbag or
the front a irbag du ring bra king or in a
sudden maneuve r. Objects nea r the air ­
bags can become projectiles and cause
in jur y when an airbag inflates.
A WARNING ~
Airbags that have deployed in a crash must
be replaced.
- Use on ly orig ina l equipment airbags ap­
proved by Aud i and installed by a trained
technician who has the necessary too ls
and d iagnost ic equipment to properly re­
p lace any airbag in your vehicle and as­
sure system effectiveness in a crash .
- Never permit salvaged or recycled air­
bags to be installed in your vehicle .

-Always carefully follow instructions from
child restraint manufacturers when in­
stalling child restraints.
A WARNING
If, in exceptional circumstances, you must
install a forward or rearward-facing child
restraint on the front passenger's seat:
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
tion.
- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child - even with an Advanced Airbag
System.
- Always carefully follow the manufactur­
er's instructions provided with the child
seat or carrier.
- 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 someone who is heavier
than the person actually sitting on the
seat . The presence of additional objects
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.

Front airbags
Description of front airbags
The airbag system can provide supplemen tal
protection to properly restrained front seat occupants.

Fig. 162 Locat ion of fron t pa ssenger' s airbag: in the in·
st rument panel
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time your
vehicle was manufactured. The safety belts
for the seats have "pretensioners " that help
to take slack out of the belt system. The pre­
tensioners are also activated by the electronic
control unit for the airbag system.
The front safety belts also have load limiters
to help reduce the forces applied to the body
in a crash.
The airbag for the driver is in the steering
wheel hub~
fig. 161 and the airbag for the
front passenger is in the instrument panel
¢ fig. 162. The general location of the airbags
is marked "AIRBAG".
There is a lot you need to know about the air­
bags in your vehicle. We urge you to read the .,..

152 Airbag system
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 extremely 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 .
-
-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

M N <( (.J

U.S. Federal Standard if a child with elec­
trical capac itance greater than the com­
bined capacitance of a typical one-year
old infant restra ined in one of the for­
ward fac ing or rearward-fac ing ch ild
seats w ith which your vehicle was certi­
fied is on the front passenger seat and
the other conditions for airbag deploy­ ment are met.
- Acc ident statist ics have shown that chil­
dren are generally safer in the rea r seat
area than in the front seating posit ion .
- For their own safety, all children, espe­
c ially 12 years and younger, sho uld al­
ways ride in the back p roperly rest rained
for their age an d size .
Advanced front airbag system
Your veh icle is equipped w ith a front Advanced
Airbag System in comp liance with Un ited
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 add it iona l
protection for the driver's and front passeng­
e r'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 enough.
The front Advanced A irbag System for the
fro nt seat occupants is not a substitute for
your safety belts . Rather, it is part of the over­
all occupant rest raint system in your ve hicle.
A lways remember that the airbag system can
only help to pro tect you, if you are s itting up ­
righ t, wearing yo ur sa fety belt and wearing it
properly. This is why you and yo ur passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your veh icle
h as been certified to meet the " low r isk" re­
q uir ements for 3 and 6 year-o ld children on
the passenger s ide 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 i n­
j ury through interaction with the front airbag
A irbag system 153
that can occur, for examp le, by being too
close to the steering wheel and instr ument
panel when the airbag inflates .
In add ition, the system has been cert ified to
comply with the "s uppression" requirements
of the Safety Standard, to turn off the front
airbag for in fants 12 months o ld and younger
who are rest rained on the front passenger
seat in child restraints that are listed in the
Standa rd
c> page 175, 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 Airbag System in your ve hicle was

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.
Airbag system 163
-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
Material - special handling may apply, see

chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts wit h pretens ioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Aud i dea ler is familiar wit h these requ ire­
ments and we recommend that you have
your dea le r perfo rm this se rv 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 Aud i,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion st ruts, shock absorbers etc. can change
the forces that are measured by the a irbag
sensors and se nt to the electron ic control
un it. Some suspension changes can, for exam­
p le, 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
changes may reduce the force levels meas­ ured by the sensors and prevent the a irbag
from deploying when it should.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire -rim combina­
tions can change Advan ced A irbag per­
formance and increase the risk of serio us
personal in jury in a crash.
- Never install suspension components
that do not have the same performance character istics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinatio ns that
have not been approved by A udi.
Knee airbags
Description of knee airbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
F ig . 1 65 Driver's knee airbag
The driver knee airbag is in the ins trumen t
pane l underneath t he steering wheel
¢ fig. 165, the airbag for the passenger is at
about the same height in the instrument pan­
el underneat h the glove compartment.
T he knee airbag offe rs additional p rotection
to the driver 's and passenger's knees and up­
per and lower th igh areas and supplements
the protection provided by the safety belts.
If t he front airbags dep loy , the knee ai rbags
also dep loy in frontal coll isions when the de­
ployment threshold stored in the contro l unit
is met
¢ page 15 7, More important things to
know about front airbags.
In addition to their norma l safety function,
safety belts help keep the dr iver or front pas­
senger in position in a fronta l collision so that
the a irbags can provide supplemental protec­
t ion .
The airbag system is not a substit ute for your
safety belt. Rather, it is part of the overa ll oc­
cupant restra int system in your vehicle. Al­
ways remember that the a irbag system can
o nly help to protect you if you are weari ng
your safety belt and wea ring i t properly. This
is why you should always wear your safety
belt, not just beca use the law requi res you to
do so
