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

Fig. 141 Location of front pass enger's a irbag: in the in
strument panel
Your veh icle 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 system senses
the position of the front seats and controls
front airbag inflation with a valve, depend ing
on the distance between the respective seat
and the steering wheel or instrument panel.
The safety belts for the seats have "preten
sioners" that help to take slack out of the belt
system. The pretensioners 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. 140 and the airbag for the
front passenger is in the instrument panel
~ fig. 141 . The general location of the airbags
i s marked "AIRBAG".
There is a lot you need to know about the air
bags in your vehicle . We urge you to read the
detailed information about airbags, safety
belts and child safety in this and the other
ch apters 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.
_&. 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.
_&. 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
b le situations that may happen during
the useful life of your vehicle .
- The Advanced Airbag System can deploy
in accordance with the "low risk" option
under the U.S. Federal Standard if a child
that is heavier 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 147
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 168 , 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 168,
-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). ..,. •
•
-Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before installing
the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime w henever the ignition is sw itched
on.
Advanced Airbag System components
The fron t passenger seat in your vehicle has a
lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sensing mat, sensors, wiring, brack
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on .
The control un it mon itors the Advanced Air
bag System and turns the airbag indicator
l ight on whe n a ma lfunction in t he sys tem
components is de tected. The function of the
airbag indicator light is described in greater
detai l below . Because the front passenger
seat contains important parts of the Ad
vanced A irbag System, you m ust take care to
prevent it from being damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/decele ration
to provide information to the Advanced Air
bag System about the seve rity of the crash.
- An electronic co ntrol unit, with integrated
c rash se nsors for front and side impacts .
T he cont ro l unit " decides " whethe r to fire
the front airbags based on the inform ation
received from the crash senso rs . The contro l
unit a lso "decides" whether the safety belt
pretensioners should be activated .

- Improper repair or disassembly of the
front passenger and driver seat will pre
vent the Advanced Airbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
dr iver seat from the veh icle .
- Never remove the upholstery from the
front passenger seat.
- Never disassemble or remove parts from the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or place them on the seat. If the weight
sensing mat in the passenger seat is punctured it cannot work properly.
- Never carry things on your lap or carry
objects on the passenger seat. Such
items can increase the weight registered
by the weight-sens ing ma t and send the
wrong info rmation to the airbag control
uni t.
- Never sto re items under the front pas·
senger seat. Parts of the Advanced Ai r
b ag System under the p assenge r seat
cou ld be damaged, prevent ing them and
the airbag system from wo rking proper
ly .
- Never place seat covers or replacement
upholste ry that have not been specifical
ly approved by A udi on the front seats.
- Seat covers can prevent the A dvanced
Air bag System from recognizing child re
straints or occupants on the front pas
senger seat and prevent the side airbag in the seat backrest from deploy ing prop
erly.
- Never use c ush ions, pillows, blankets or
similar items on the front passenger
seat. The add it iona l padd ing will prevent
the weight-sensing mat in the seat from
accu rately reg iste ring the c hild restra int
or person on the seat and prevent the
Adva nce d Airb ag System from func tion
ing properly .
-If you mus t use a child restra int on the
front passenger seat and the ch ild re- straint manufacture
r's instructions re
qu ire the use of a towel, foam cushion or
something e lse to properly pos ition the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes

inspected by your authorized A udi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide airbags supp lement the protection of
fered by the front three-poi nt safety belts
with pretensioners and load limiters a nd the
adjustable head rest raints to help redu ce the
risk of inj ury in a wide range of accident and
c rash situations. Be s ure to read the impor
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need A irba g System
and t he activation of the safety belt preten
sioners depend on the deceleration measured
by the crash sensors and registered by the
electron ic control unit. The amount of infla
tion of the front airbags can a lso be adapted
to the front sea t pos ition, depending on the
distance between the respect ive front seat
and the steer ing w heel or instrument panel as
registered by sensors in the seats. Crash se·
verity depends on speed and decelerat ion as
well as the mass and st iffness of t he vehicle
o r object involved in the crash .
On the passenger side, regardless of safety
belt use, the ai rbag w ill be tu rned off if the
we ight on the passenger seat is less than the
amount programmed in the e lectron ic control
u nit. The front airbag on the passenger side
will a lso be turned off if one of the child safe -
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recogni zed on the seat . The
PAS SENGER AIR .,..
152 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 143.
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.

156 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.

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 159
-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
