138 Airbag sys te m
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 airbags.
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 rememb er: 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
ter the first co llision.
This is just one of the reasons why an airbag is
a supplementary restraint and is not a substi­
tute for a safety belt . The airbag system
works most effect ively when used with the
safety belts. Therefore, always properly wear
your safety belts¢
page 128.
A WARNING
Sitting too close to the steer ing wheel 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 adaptive 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 131, 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 severely injured or killed when an
airbag 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 119.
-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 inal 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 instru ctions from
c hild restraint manufacturers when in­
sta lling 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 supplemental
protection to properly restrained front seat occupants.
Fig. 141 Loc ation of driver airbag: in steering w heel
Fig. 142 Loc ation of front passenger's a irbag: in the in·
strument 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 system senses
the position of the front seats and controls
front airbag inflation with a valve, depending
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 pretens ioners 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
q fig. 141 and the airbag for the
front passenger is in the instrument panel

-The Advanced Ai rbag System can deploy
in accordance wi th the .,low risk" opt ion
for 3- and 6-year-old children under the U.S. Federal Standard if a chi ld w ith elec­
trical capac itance greater than the com­
bined capacitance of a typical one-year
old infan t restra ined in one of the fo r­
wa rd fac ing or rearward-fac ing ch ild
seats w ith which you r vehicle was cer ti­
fied is on the front passenger seat and
the other conditions for airbag deploy­ ment are met.
- Accident statist ics have shown that chil­
dren are generally safe r in the rear seat
area than in the front seating posit ion.
- For their own safety, all children, espe­
cially 12 yea rs and younger, sho uld al ­
ways ride in the back properly rest rained
for their age and size.
Advanced front airbag system
Your veh icle is equipped w it h a front Advanced
A irbag System in compliance with U nited
States Federal Motor Vehicle Safety Standard
208 as applicab le at the time your vehicle was
manufactured.
The front Advanced Airbag System supple­ ments the safety belts to provide add it ional
p rotection fo r th e driver's and front passeng­
e r' s heads and upper bodies in fronta l crashes.
The airbags in flate only in frontal impacts
when the vehicle dece le rat ion is high enough .
The front Advanced A irbag System for the
fro nt sea t occ upants is no t a subs titu te for
your safety bel ts. Ra ther, it is p art of t he over­
all occupant restraint system in your veh icle.
A lways remember that the airbag system can
only help to protect yo u, if you are s itting up­
right, wearing yo ur 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 .
The Advanced Airbag System in your veh icle
has been certified to meet the " low r isk" re­
qu irements for 3 and 6 year-o ld childre n on
the passenge r side and very small adu lts on
A irbag system 143
the d river side . The low risk deployment c rit e­
ria are intended to help reduce the risk of in­
ju ry 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 add ition, the system has been certified to
comply with the "s uppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are res trained on the fro nt passenger
seat in child rest raints that ar e listed in the
Standard
¢ page 165, Child restraints and
Advanced front airbag system.
"Suppress ion " 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 i n one
of the rear-fac ing o r forward-facing infant
restrai nts listed in Federal Motor Vehicle
Safety Standa rd 208 wi th wh ich the Ad­
vanced Ai rbag System in your ve hicle was
cert ified. For a listing o f the chi ld res traints
t ha t were used to certify your vehicle's com ­
pliance wit h the US Safety Standa rd
¢ page 165,
-When a person is detected o n the front pas ­
senger seat that has an e lectrical capaci­
tance that is more t han the tota l electrical

old restrained in one of the rear-facing o r
forwa rd -facing infant restraints ( listed in
Fede ral Motor Vehicle Safety Standard 208
w ith which the Advan ced A irbag System in
your veh icle was certi fied), the front air bag

144 Airbag sys tem
If the tota l electrical capacitance registe red
on the front passenger seat is more than that
of a typ ica l 1 year-old, but less than the
weight of a small adult, the front a irbag on
the passenger side may deploy (the
PA SSE N­
GER AIR BAG OFF
li ght does not come on).
For e xample , the airbag m ay deploy if :
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld seats listed
¢ page 165),
-a chi ld who has outgrown child restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light in the center
of the instrument panel wi ll come on and stay
on.
If the front passenger airbag deploys, the
F ederal Standard requires the airbag to meet
the " low risk" deployment criteria to help re­
d uce the risk of injury through interaction
with the airbag. "Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the electronic control un it
¢ page 149 .
Alw ays rem ember : Even though your vehicle
is equipped with Advanced Airbags, the safest
place for children is properly restrained on the
back seat . Please be sure to read the impor­
tant information in the sect ions that follow
and be sure to heed a ll of the WARNINGS.
.&_ WARNING
To reduce the risk of injury when an airbag
inflates, a lways wear safety belts prope rly.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way, your risk of injury is much higher.
- You w ill also receive serio us injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in ­
flates - even with an Advanced Airbag
¢page 137.
.&_ WARNING
A child in a rearward-fac ing ch ild seat in­
stalled on the front passenger seat will be
seriously inju red and can be killed if the
front airbag inflates - even w ith an Ad­
van ced A irbag System.
- Altho ugh the Advanced Airbag System in
your veh icle is designed to turn off the
front airbag when a rearward-facing
child restraint has been instal led on the
front passenger seat, nobody can abso ­
lutely g uarantee that dep loyment is im­
possible in all conceivable situations that
may happen dur ing the usefu l life of your
veh icle.
- The inflating airbag will h it 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 rearward-facing ch ild re­
straints on the rear seat .
- If you must install a rearward fac ing
child seat on the front passenger seat because of exceptional circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immed i­
a tely insta ll the rear-facing child seat in a
rear seat ing pos ition and have the airbag
system inspected by your Audi dealer.
.&_ WARNING ,..___
If, in except iona l circumstances, you m ust
install a forward -facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and s ide a irbag.
- Never p ut the forward-facing child re­
straint up against or very near the instru­
ment panel.
- Always move the passenger seat into its
rearmost pos ition in the seat's fore and
aft ad justment range, as far away from
the airbag as possible, before install ing
the forward-fac ing ch ild restra int. The
-

backrest must be adjusted to an upright
posit ion.
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenger detection
system in the seat to s ignal to the A irbag
System that the seat is occupied by a person when it is not, or to signa l that it
is occupied by som eone who is heavier
than t he pe rson actually s itting on t he
sea t. T he presence of addition al obje cts
cou ld cause the passenger front airbag
to be t urned on when it sho uld be off, or
cou ld cause t he airbag to work in a way
that is different from the way it wou ld
have worked without the object on the
seat.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime w henever the ignition is switc hed
on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
A irbag System in it. These parts incl ude t he
c a pac itive passenger de te ct ion sys tem, wir­
ing, b racke ts, and more . The cont ro l uni t
monitors the system o n the front passenger
seat when the ign ition is switched on and
turns the airbag indicator light on w hen a
malfunct ion in the one of the system compo­
nents is detected ¢
page 150. Because the
fro nt passenge r seat contains important parts
of the Advanced Airbag System, you must
take care to p revent it from bei ng damaged.
D amage 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 sensors in the front of the veh icle tha t
measure ve hicle acceleration/dece le ration
to provide information to the Advanced Air­ bag System about the severity of the crash.
A irbag system 145
- An elect ron ic contro l unit, with integrated
crash sensors fo r front and side impacts .
T he control un it "decides" whether to f ire
the front a irbag s based on the informat ion
received from the crash sensors. The control
unit also "decides" whether the safety belt
prete nsione rs should be act iva ted .
- An Advanced A irbag w it h gas generator and
cont ro l valve for the driver ins ide the steer ­
ing wheel h ub.
- An Advanced A irbag w ith gas generator and
cont ro l valve inside the instrument pa nel for
the front passenger .
- A capacit ive passenger detection system un ­
de rneath the front passenger seat cover .
This system measu res the ele ct rical capac i­
t ance of the perso n in the seat. The informa ­
t ion regis tered is se nt cont inuo usly to the
elec tronic con trol un it to regu late dep loy­
ment of the front Advanced A irbag on the
passenger side.
-An airbag monitoring system an d ind icator
light in the instr ument cluster ¢

-A senso r in each front seat registers the dis ­
tance between the respective seat a nd the
steering whee l or instrument panel. The in­
formation registered is sent cont inuo usly to
the electron ic contro l unit to regulate de­
ployment of the front Adva need A irbags .
- The
PASSENGER AIR BAG OFF li ght comes
on and stays on in the center of the instr u­
ment panel ¢
page 150, fig. 144 and tells
you whe n the front Advanced Airbag on the
passenger side has been tu rned off.

elec tro nic con trol un it.
A WARNING
D amage to the fron t passenger se at can
p revent the front air bag from work ing
p roperly.
- Imp roper repai r or disassembly of the
front passenge r and dr iver seat will pre­
vent the Advanced Airbag System from
functioning properly.

-Never place or attach accessories or o th ­
er objects (such as cup hol ders, 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 a reas and yourself. These
objects co uld cause injury in a crash, es­
pecially when the airbags inflate .
- Never recline the front passe nger's seat
to transport objec ts. Items can also
move into the area o f the side airbag or
the front airbag during braking or in a
sudden maneuver . Objects near the air­
bags can become project iles and cause
injury, part icularly when the seat is re­
cl ined .
- Never place or transport ob jects on the
front passenger seat. Objects on the
front passenger seat could cause the ca­ pacitive senso r in the seat to s ignal to
airbag system that the seat is occupied
by a person when it in fa ct is not, o r that
the person on the se at is he avier than he
or she actually is. The change in electric
capacitance beca use of such objects can
cause the passenger front airbag to be
turned on when it sho uld be
off, or can
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout objects on the seat.
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenge r detection
system in the s eat to s ignal to the A irbag
System that the seat is oc cupied by a
pers on when it is not, or to sign al th at it
is occupied by someone who is heavier
than the pe rson actually s itting on the
seat . The presence of an object co uld
cause the passenger front a irbag to be
turned on when it sho uld be
off, or co uld
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout the object on the seat. A

The PASSENGER AIR BAG OFF Light is Located
in the cen ter of the instr ument panel
~fig. 144.
The PASSENGER AIR BAG OFF Light will come
on and stay on to tell you when the front Ad­
vanced A irbag on the passenger side has been
turned off by the electronic control unit. If the
bulb for the
PASSENGER AIR BAG OFF Light
burns out, the airbag indicator Light
fl will
come on to signal a malfunction in the Ad­
vanced A irbag System . Although the burned­
out bulb will not change the way the front
passenger's frontal airbag works, it w ill no
longer be possible to use the
PASSENGER AIR BAG OFF
Light to make su
re that the airbag
on/off status is correct for the occ upant on
the front passenger seat . Have the airbag sys ­
tem inspected immediately by your author­
ized Audi dealer.
The PASSENGER AIR BAG OFF Light will blink
for about
5 seconds when:
- the ignition is sw itched on and
- t he capacitive passenger detection system,
whi ch switches the front seat passenger's
frontal Advanced Airbag on and off, detects
a change in the status of the front passen­
ger seat.
As soon as the
PASSENGER AIR BAG OFF
light stops blinking, always make sure that
t h e airbag status (on or off) as shown by the
PASSENGER AIR BAG OFF Light is proper for
the age, size and e lectrical capacitance of the
person occupy ing the front passenger seat.
Always make sure that the safety belt for the
front passenger seat is properly fastened .
The PASSENGER AIR BAG OFF light will
show the status of the front seat passenger's
frontal Advanced Airbag a few seconds after
the ignition is switched on and the airbag in­
dicator light goes off . The PASSENGER AIR
BAG OFF light:
- will stay on if the front passenger seat is not
occupied;
- will stay on if the electrical capacitance
measured by the capacitive passenger de­
tection system for the front passenger seat
equals the combined capacitance of an in­
fant up to about one year of age and one of
the rearward-facing o r forward-facing child
restraints Listed in Federal Motor Vehicle

Repair, care and disposal of the airbags
Parts of the a irbag system are installed at
many different places on your Audi. Installing,
removing, servic ing or repairing a part in an
area of the vehicle can damage a part o f an
airbag system and prevent that system from
working properly in a co llision.
There are some important things you have to know to make sure that the effect iveness of
the system will not be impaired and tha t dis ­
carded components do not cause injury or po l­
l ute the env ironment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag
from deploy ing when needed o r deploying
an airbag unexpected ly:
- Never cover, obstruct, o r change the
steering wheel ho rn pad or airbag cover
o r th e instrument pane l 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 ho rn pad or instrumen t
pane l, use only a soft, d ry cloth or one
mois tened w ith plain wate r. Solven ts or
cleaners co uld damage the airbag cover
or change the stiffness o r strength of the
A irbag sys tem 153
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the a irbag system.
- All work on the steering wheel, instru­
ment panel, front seats or e lectr ica l sys­
tem (including the installation of audio
equ ipment, cellu lar telephones and CB
radios, etc.) must be performed by a
qualified technic ian who has the training
and specia l equipment necessary.
- For any work on the airbag system, we strongly recommend that yo u see your
author ized Audi dealer or qualif ied work­
shop.
- Never modify the front bumper or pa rts
of the vehicle body.
- Always make sure that the s ide a irbag
can inflate without inte rfe rence:
- Never in.stall seat covers or rep lace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat c ushions that
cover the areas where the side a irbags
i nflate.
- Damage to the orig inal seat cove rs or
to the seam in the area of the side a ir­
bag module must a lways be repaired
i mmediately by an author ized Audi
dealer.
- The airbag system can deploy on ly once.
After an a irbag has been deployed, it
m ust be replaced with new replacement
pa rts des igned and app roved espec ially
for your Aud i mo del ve rsion. Replace­
men t of comple te 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
