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, a lways:
• Adjust the dr iver's seat and steering wheel
properly ¢
page 145,
• Adjust the front passenger's seat properly
¢page 62,
• Wear safety be lts properly ¢ page 15 7,
• Always properly use the proper child re-
stra int to protect children¢
page 186.
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 properly . Therefore in order to he lp the
a irbag to do its job, it is important, both as a
d river and as a passenge r to sit properly at all
times.
By keeping room between your body and the
steering wheel and the front of the passenger
compartment, the airbag ca n inflate fully and
comp letely and provide supp lemental p rotec
tion in ce rtain frontal collisions¢

There is a lot that the driver and the passen
gers can and must do to help the individua l
safety features ins talled in your A udi work to
gether as a system.
Prope r seat ing pos ition is important so that
the front airbag on the driver s ide can do i ts
job. If yo u have a physical impa irment or con- dition that prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the peda ls , spec ial
modifications to your vehicle may be necessa
ry.
Contact your a uthorized Audi dea ler, or call
Audi C ustomer Re lations at 1-800-822-2834 .
When the airbag system dep loys, a gas gener
ator will f ill the ai rbags, break open the pad
ded covers, and inf late between the steering
whee l and the dr iver and between the instru
ment pane l and the front passenger. The air
bags will deflate immediately after dep loy
ment so that the front occupants can see
th rough the w indshield aga in without inter
ruption .
All of th is take s place in the blink of an eye, so
fast that many people don't even realize that
the a irbags have dep loyed . The airbags also
inflate with a g reat dea l of force and nothing
shou ld be in their way when they deploy.
F ront a irbags in combination with properly
worn safety bel ts slow down and lim it the oc
c u pant's forward movement. Together they
help to prevent the drive r and front seat pas
senger from hitting parts of the inside the ve
hicle while reducing the forces acting on the
occupant dur ing the crash. In this way they
help to reduce the risk of injury to the head
and uppe r body i n the c rash . A irbags do not
protect the a rms or the lower parts of the
body.
Both front a irbags w ill not i nflate in all fronta l
collisions . The t rigge ring of the a irbag system
depends on the vehicle dece lerat ion rate
c aused by the co llision and reg istered by the
elect ron ic cont ro l u nit. If t his rate is below
the re ference value programmed into the con
trol unit, the airbags will not be trigge red ,
even though the car may be bad ly damaged as
a res ult of the collision . Veh icle damage, re
pair costs or even the lack of veh icle damage
is no t necessarily an indication of whether an
airbag should inflate or not .
It is not possib le to define a range of vehicle
speeds that w ill cover every possib le kind and .,.
angle of impact that will always trigger the
airbags, since the circumstances will vary con
siderably between one collision and another.
Important factors include, for example, the nature (hard or soft) of the object which the
car hits, the angle of impact, vehicle speed,
etc. The front airbags will also not inflate in
side or rear collisions, or in ro ll-overs .
Alwa ys rem ember : Airbags will deploy only
once, and only in certa in kinds of collisions .
Your safety belts are always there to offer pro
tection in those s ituations in which airbags
are not supposed to deploy , or when they have
a lready deployed ; fo r example , when yo ur ve
h icle strikes or is struck by another after the
first collision .
This is just one of the reasons why an a irbag is
a supplementary restra int and is not a s ubst i
tute for a safety belt . The airbag system
works most effectively when used with the
safety belts. Therefore, always properly wear
your safety belts
¢ page 154.
A WARNING
Sitting too close to the steer ing wheel or
instrument panel will decrease the effec
tiveness of the airbags and will increase
the risk of pe rsonal injury in a co llision .
- Never sit closer than
10 inches (25 cm)
to the stee ring wheel or instrument pan
el.
- If you cannot sit more than
10 i nches
(25 cm) from the steer ing wheel, investi
gate whether adaptive equipment may
be available to help you reach the pedals
and increase your seating dis tance from
the steering wheel.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way, yo ur risk of inj ury is much highe r.
- You w il l also receive serio us inju ries 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 r isk o f injury when an air
bag inflates, a lways wear safety belts
proper ly ¢
page 157, Safety belts .
Airbag system 163
-Always make certain that chi ld ren age 12
or younger a lways ride in the rear seat. If
children are not properly restrained, they may be severe ly inju red or killed when an
airbag inf lates .
- Never let ch ildren ride unrestra ined or
improperly restrained in the vehicle . Ad
just the front seats prope rly.
- Never ride with the backrest reclined.
- Always sit as far as possible from the
steer ing whee l or the instrument pane l
¢page 145.
-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 f loor in front of the seat to
he lp prevent serio us in juries to the legs
a nd h ips if the airbag inflates.
- Never recline the front passenger 's seat
to tra nsport objects. Items can a lso
move i nto the area of the s ide a irbag or
the front a irbag du ring bra king or in a
sud den maneuve r. Obje cts ne ar the air
bags can become projectiles and cause
injury when an airbag inflates.
_&. WARNING ~
A irbags that have de ployed in a crash must
be replaced.
- Use on ly original equipment airbags ap
proved by Audi and installed by a trai ned
technician who has the necessary too ls
and d iagnost ic equipment to properly re
place any airbag in your vehicle and as

Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants.
F ig . 175 Location of driver airbag: in steer ing whee l
Fig. 176 Location of front passenger's airbag: in the in
strument panel
Your veh icle is equipped with an "Advanced
A irbag System" in compliance with United
States Federal Motor Vehicle Safety Standard ( FM VSS) 208 as app licab le at the time your
ve hicl e was manufac tured. The system senses
the position of the front seats and controls
front airbag inflation with a valve, depending
on the distance between the respect ive seat
and the steering wheel or instrument panel.
The safety belts for the seats have "preten
sioners" that he lp to take slack out of the belt
system . The pretensioners a re also activated
by the electron ic cont ro l unit for the ai rbag
system. T
he front safety belts also have load limiters
to help reduce the forces applied to the body
i n a crash .
T he airbag for the drive r is in the stee ring
whee l hub¢
fig. 175 and the airbag for the
front passenger is in the instrument panel
~ fig. 176. The general locat ion of the a irbags
is marked "AIRBAG".
T here is a lot you need to know about the ai r
bags in your vehicle. We urge you to read the
detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up th e owner's literature.
P lease be sure to heed the WARNINGS -they
are extremely importa nt for your safety and
the safety of your passengers, especially in
fants and small chi ldren.
_&. WARNING
Neve r rely on airbags alone for p rotection.
- Even w hen they deploy, airbags provide
only s upplement al pro te ctio n.
- Airbag work most effect ive ly when used
with p roperly wor n safety bel ts.
- Therefore, always wea r you r safety belts
a nd make sure tha t eve rybody in your ve
h icle is properly res trained.
_&. WARNING
A pe rson on the front passenger seat, es
pe cial ly infa nts and sm all ch ildren, w ill re
ceive serio us inju ries and can even be kil
l ed by being too close to the airbag when
it inflates .
- Although t he Advanced Airbag System in
your veh icle is designed to tur n off the
front passenger airbag if an infant or a
small child is on the front passe nger
seat, nobody can absolutely guarantee
that deployment under these special
conditions is imposs ible in all conceiva
b le sit uat ions that may happen dur ing
the useful life of your vehicle.
- The Advanced Airbag System can dep loy
i n acco rdance with the "low risk" option
unde r the U.S . Feder al Standa rd if a child
th at is heav ie r than the typical one -year
-
.
old child is on the front passenger seat
and the other conditions for airbag de
ployment are met.
- Accident statistics have shown that chil
dren are generally safer in the rear seat
area than in the front seating position.
- For their own safety, all children, espe cially 12 years and younger, should al
ways ride in the back properly restrained
for their age and size.
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 additional
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 deceleration is high enough .
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts. Rather, it is part of the over
all occupant restraint system in your vehicle.
Always remember that the ai rbag system can
only help to protect you, if you are sitting up right, wearing your safety belt and wearing it
properly . This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be.
T he Advanced Airbag System in your vehicle
has been certified to meet the "low risk" re
quirements for 3 and 6 year-old children on
the passenger side and very small adults on
the driver side. The low risk deployment crite
ria are intended to help 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 instrument panel when the airbag inflates.
In addition, the system has been certified to
comply with the "suppression" requirements
Airbag system 167
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are restrained on the front passenger
seat in child restraints that are listed in the
Standard ¢
page 188 , Child restraints and
Advanced Airbags .
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is re
strained on the front passenger seat in one
of the rear-facing or forward-facing infant restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad
vanced Airbag System in your vehicle was
certified . For a listing of the child restraints
that were used to certify your vehicle's com pliance with the US Safety Standard
¢page 188,
-weight less than a threshold level stored in
the control unit is detected on the front pas
senger seat.
When a person is detected on the front pas
senger seat, weighing more than the total
weight of a child that is about 1 year old re
strained in one of the rear-facing or forward
facing infant restraints (listed in Federal Mo
tor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified), the front airbag on the passen ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to
tal weight on the front passenger seat that re
quires the front airbag to be turned off. If the
PASSENGER AIR BAG OFF light does not
come on, the front airbag on the passenger
side has not been turned off by the control unit and can deploy if the control unit senses
an impact that meets the conditions stored in
its memory.
If the total weight on the front passenger
seat is more than that of a typical 1 year-old ,
but less than the weight of a small adult, the
front airbag on the passenger side may deploy
(the
PASSENGER AIR BAG OFF light does not
come on). ..,. •
•
172 Airbag system
must always sit in an upright position,
must not lean against or place any part
of their body too close to the area where
the airbags are located .
- Occupants who are unbelted, out of posi
tion or too close to the airbag can be se riously injured by an airbag as it unfolds
with great force in the blink of an eye
~page 163.
A WARNING
A child in a rearward-facing child safety
seat installed on the front passenger seat
will be seriously injured and can be killed if
the front airbag inflates -even with an Ad
vanced Airbag System.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door or roof.
- Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer.
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
or by being 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 air
bags during braking or other sudden ma
neuver and become dangerous projec- tiles that can cause serious personal in
jury if the airbags inflate.
- Never place or attach accessories or oth
er objects (such as cupholders, tele phone brackets, large, heavy or bulky ob
jects) on the doors, over or near the area marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be
tween those areas and yourself. These
objects could cause injury in a crash, es
pecially 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 airbag during braking or in a
sudden maneuver. Objects near the air
bags can become projectiles and cause
injury, particularly when the seat is re
clined.
A WARNING
'-
The fine dust created when airbags deploy
can cause breathing problems for people
with a history of asthma or other breath
ing conditions.
- To reduce the risk of breathing problems, those with asthma or other respiratory
conditions should get fresh air right
away by getting out of the vehicle or
opening windows or doors.
- If you are in a collision in which airbags
deploy, 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.
176 Airbag system
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 cu
pholders 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 be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed,
it must be replaced with new replace
ment parts designed and approved espe
cially for your Audi model version. Re
placement of complete airbag systems
or airbag components must be per
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty
& Main
tenance booklet under
AIRBAG REPLACE
MENT RECORD .
-In accidents when an airbag is deployed,
the vehicle battery separates the alterna
tor and the starter from the vehicle elec
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter
rupter must only be performed by a
qualified dealer -risk of an accident!
- 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
www.dtsc.ca.gov/hazardouswaste/per
chlorate. When the vehicle or parts of the restraint system including airbag modules
safety belts with pretensioners are scrap
ped, all applicable laws and regulations
must be observed. Your authorized Audi
1J1-
dealer is familiar with these requirements
and we recommend 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 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 electronic 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 .
The sensors in the safety belt buckle for the
d river and front passenger seat tell the elec
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high
er rate of vehicle deceleration than if the safe
ty belt is not being used. Therefore, in a par
ticular collision, it is possible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen
sors can send the correct information about
safety belt use to the electronic control unit.
.&_ 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
Airbag system 177
characteristics as the components origi
nally installed on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
.&_ WARNING
= -
Items stored between the safety belt buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con
trol module and prevent the Advanced Air bag System from working properly.
-Always make sure that nothing can inter-
fere with the safety belt buckles and that
they are not obstructed.
Knee airbags
Description of knee airbags
Applies to vehicles: wit h knee airbags
The knee airbag system can provide supple
mental protection to properly restrained
front seat occupants.
Fig. 179 Driver 's knee airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
Q fig . 179, the knee airbag for the passenger
is at about the same height in the instrument
panel 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 deploy in frontal collisions when the de ployment threshold stored in the control unit

The knee airbag system has been designed so
that the airbags for the driver and front pas
senger deploy in certain but not all frontal
collis ions .
I f the front airbags deploy , the knee airbags
also deploy in fronta l collis ions when the de
p loyment threshold stored in the control unit

When the system dep loys, the airbags fill
with a prope llant gas, and inflate between the
l ower part of the instrument panel and the
driver and the lower part of the instrument panel and the fron t passenger <=>

extremities .
All of this takes place in the blink of an eye, so
fast that many people don't even reali ze that
t he airbags have deployed . The airbags also
inflate w it h a great deal of force and it is im
portant for occ upant safety that not hing
should be in the ir way when they dep loy .
Fully infla ted airbags in comb ination with
properly worn safety belts slow down and lim

to reduce the r isk of injury .
Important safety instructions on the
knee airbag system
Applies to vehicles: with knee a irbags
Airbags are only supplemental restraints. Al
ways wear safety belts correctly and ride in a
proper seating position .
There is a lot that you and your passenge rs
must know and do to help the safety be lts a nd
ai rbags to provide supp lemen tal protection .
_.6 WARNING
An inflating knee airbag can cause ser ious
injury. Wear ing safety belts incorrectly and
improper seating positions increase the
r isk of serious personal injury and death
whenever a veh icle is being used.
A irbag system 179
-The knee a irbag system cannot p rotect
you proper ly if you a re seated too close
to any of the airbag locat ions. When ad
justing their seat pos itions, it is impor
tant that both the driver and the front passenger keep the ir upper bod ies and
knees at the following m inimum safe
distances :
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru
ment panel.
- at least 4 inches (10 cm) between the knees and the lower part of the instru
ment panel.
- The risk of personal in jury increases if
you lean forward or to the s ide, or if the
seat is improperly positioned and you are
not wearing yo ur safety belt . The risk i n
creases even more should the ai rbag de
ploy .
- Always ma ke sure that the knee a irbag
can inflate without inte rfe rence. Objects
between yo u and the airbag can inc rease
the risk of in jury in an accident by inte r
fering w ith the way the a irbag deploys or
by being p ushed into you as the airbag
deploys.
- Never let anybody, especia lly children
or anima ls ride in the footwell in front
of the passenge r seat. If the airbag de
ploys, th is can result in serious or fa tal
i njur ies.
- Never carry obje cts of any kind in the
footwe ll area in front of the dr iver' s or
passenger 's sea t. Bulky objects (shop
ping bags , fo r example) can interfere
with o r prevent proper deployment of
the airbag. Small objects can be
thrown through the ve hicle if the air
bag deploys and injure you or your pas
sengers .
- Make sure there are no cracks, deep
scratches or other damage in the area of
the instrument panel where the knee air
bags are located.
- If ch ildren are incorrectly seated, their
risk of injury increases in a collision
