If the front passenger airbag is turned off , the
PASSENGER AIR BAG OFF light comes on in
the instrument cluster and stays on .
I f the front passenger airbag deploys, the
F ederal Standard requires the airbag to meet
the " low risk" deployment criteria to reduce
the r isk of in jury through interaction with the

A lw ays r emember, a chi ld seat or infant carri­
er installed on the front seat may be s truck
and knocked out of position by the rap idly in ­
flati ng passenger's a irbag i n a frontal colli­
sion . The airbag could greatly reduce the ef­
fectiveness of t he ch ild restrai nt and even se­
r io usly in ju re the child during infla tion.
For this reason, and because the back seat is
the safest place for chi ldren - when p roperly
r estra ined a ccord ing to the ir age and size - we
strongly recommend t hat childre n always si t
in the back seat

& WARNING
-
A child in a rearward -facing child seat in ­
stalled on the front passenger seat will be
ser iously injured and can be killed if the
front airbag inflates - even with an Ad­
vanced Airbag System.
- The inflating a irbag will hit the child seat
or infant carrier w ith great force and w ill
smash the ch ild seat and child against
the bac krest , cen ter armres t, door or
roof.
- Always install rear-facing child seats on
the rear seat.
- If you must i nstall a rearward facing
child seat on the front passenge r seat
because of except iona l circumstances
and the
PASSENGER AIR BAG OFF ligh t
does not come on an d stay on, immedi­
a tely install the re ar-facin g chi ld seat in a
rear seating position and have the ai rbag
system inspected by your Aud i dealer. -
Forwa rd- facing child seats installed on
the front passenger 's seat may interfere
wit h the dep loyment of the a irbag and
cause serious persona l injury to the
child .
& WARNING
-If, in except ional circumstances, you m ust
i nstall a forward-facing child restraint on
the front passenge r's seat:
- Always make sur e the forward-facing
seat has been designe d and certified by
its m anufacture r for u se on a fron t se at
wit h a passenger fron t and s ide airba g.
- Never p ut t he fo rward -facing child re­
s tra int up agains t or ve ry near the instru­
men t pa nel.
- Always move the passenge r seat into it s
rearmost pos ition in the seat' s fore and
aft a djustmen t range, as fa r away from
the air bag as possible before installing
the forwar d-facing ch ild restra int . The
backrest must be ad justed to an upright
position.
- Make sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the
time whenever the ignit ion is switched
on .
& WARNING
-To reduce the risk of serious injury, make
sure that the
PASSENGER AIR BAG OFF
light w ill be display ed whe nev er a child re­
straint is insta lled on the front pa ssenger
se at and the igni tion is sw itche d on .
- If the
PASSENGER AIR BAG OFF light
does no t stay on, per form the che cks de­
scribed
c::> page 1 49, Monitoring the Ad­
vanced Airbag System.
- Ta ke t he chi ld restraint off the fron t pas­
senger sea t and inst all it prope rly at one
of the rear seat positions i f the
PASSEN­
GER AIR BAG OFF
li ght does not stay on.
- Have the airbag system inspected by
your Aud i dea le r i mmediately.

-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

-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
-

146 Airbag system
-Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
driver seat from the vehicle.
- 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 put them on the seat. The capacitive
passenger detection mat in the front
passenger seat will not function properly
if it is punctured .
- Never carry things on your lap or carry
objects on the front passenger seat.
Such objects can influence the capaci­
tance registered by the capacitive pas­ senger detection system, so that incor­
rect information is provided to the airbag
control unit.
- Never store items under the front pas­
senger seat. Parts of the Advanced Air­
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper­
ly.
- Never place seat covers or replacement upholstery that have not been specifical­
ly approved by Audi on the front seats.
- Seat covers can prevent the Advanced
Airbag System from recognizing child re­
straints or occupants on the front pas­
senger seat and prevent the side airbag
in the seat backrest from deploying prop­
erly .
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys­
tem on this seat.
- Never use cushions, pillows, blankets, or
similar items on the front passenger
seat. The additional layers prevent the
capacitive passenger detection system
from accurately measuring the capaci­
tance of the child safety seat and/or the
person on the seat and thus keep the Ad- vanced Airbag System from working
properly.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device or power inverter) on the
front passenger seat if the device is con­ nected to the 12-volt socket or the ciga­
rette lighter socket. Such devices can in­
fluence the capacitance registered by the
capacitive passenger detection system,
so that incorrect information is provided
to the airbag control unit.
- If you must use a child restraint on the
front passenger seat and the child re­
straint manufacturer's instructions re­
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re­
straint is installed on the front passen­
ger seat.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install child restraint in a rear seat­
ing position and have the airbag system
inspected by your Audi dealer.
_& WARNING
If the front passenger seat gets wet, dry it
immediately.
- If liquid soaks into the front passenger
seat, this can keep the airbag system
from working properly and may, for in­ stance, deactivate the passenger frontal
airbag. If this happens, the
PASSENGER
AIR BAG OFF
light will come on and stay
on together with the airbag indicator light min the instrument cluster.
- If liquid is pooled on the seat, but has
not soaked in, this may also keep the air­
bag system from working properly and
cause the passenger frontal airbag to be
enabled (turned on), even though there
is a properly installed child restraint sys­
tem on the seat. Wet towels or other wet
things on the seat cushion can have the

same effect. If the front passenger
frontal a irbag is turned on, the
PASSEN ­
GER AIR BAG OFF
light light will go out.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side airbags supplement the pro tection of­
fe red by the fro nt three -point safety be lts
with pretensioners and load limiters and the
adj ustab le head restra ints to he lp reduce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the impor­
tan t information about safety and heed the
WARNINGS in this chapter .
Deployment of the Advanced A irbag System
and the act ivation of the safety be lt preten­
sioners depend on the decelerat ion measured
by the crash sensors and registered by the
electronic control un it . The amount of infla ­
tion of the front airbags can also be adapted
to the front seat position, depending on the d istance between the respe ctive front seat
and the steering whee l or inst rument panel as
registered by sensors in the seats. Crash se­
verity depends on speed and deceleration as
well as the mass and stiffness of the vehicle
or object invo lved in the crash .
On the passenger s ide, regard less of safety
be lt use, the front passenger fronta l airbag
will be t urned off if the electrical capacitance
measured by the capacitive passenger detec­
tion system on the front passenge r seat is less
than the amount programmed in the electron­
ic control unit . The front passenger fronta l air ­
bag will a lso be turned off if the capac itance
measured by the system for the front passen­
ger seat eq ua ls tha t of an infant o f abo ut one
year of age in one o f the child seats that was
used to cert ify the Advanced Airbag System
under Fede ral Motor Vehicle Safety Standard
208 . T he

A WARNING
To reduce the risk of injury w hen an airbag
in flates, always wear safety be lts p ro perly.
- If you are unrestra ined, leaning forward,
sitt ing s ideways or out of pos ition in any
way, your ris k of injury is m uch higher.
- You will a lso receive serious injuries and
could even be killed if you are up aga inst
the airbag o r too close to it when it in­
flates -even w it h an Advanced A irbag

More important things to know about
front airbags
Fi g. 14 3 In flated front a irbags
Safety belts are important to help keep front
seat occupants in the proper seated position
so that ai rbags can unfold p roper ly and pro­
v ide s upplementa l pro tect ion in a fron tal col­
lis ion .
T he front airbags a re des igned to provide ad­
di tional protection fo r the chest and fa ce of
the d river a nd the front seat passenger when :
- safety belts are worn properly ,
- the seats have been positioned so that the
occupant is properly seated as far as poss i­
b le from the airbag ,
- and the head restraints have been properly adjusted .
Because airbags inflate in the bli nk of an eye
wi th great force, things you have on your lap
or have placed on the seat cou ld become dan ­
gerous p rojecti les, and be pushed in to you if
t h e a irbag inf lates.
When an airbag deploys, fine dust is re leased.
This is norma l and is not caused by a fire in .,,.

148 Airbag sys tem
the vehicle. This dust is made up most ly o f a
powder used to lubricate the airbags as they
deploy . It cou ld irritate sk in .
I t is important to remember that whi le the
supp lemental airbag system is designed to re ­
duce the likelihood of serious injuries, other
in ju ries, for example swelling, bruising and
minor abrasions, can also happen when air­
bags inflate. Airbags do not protect the arms
or the lower parts of the body . Front airbags
supplement the three-poi nt safety belts only
in some frontal co llisions in which the vehicle
dece le ra ti on is high enough to deploy the air­
bags.
Front airbags will not deploy:
- if the ignit io n is switched off when a crash
occurs,
- in s ide collisions,
- in rear-end collisions,
- in ro llovers,
- when the crash deceleration measured by
the airbag system is less than the minimum
threshold needed for airbag deployment as
registered by the e lectronic control unit.
Th e front pa ssenger airbag al so will not
d epl oy:
- when the front passenger seat is not occu ­
pied,
- when the electrical capacitance measured by
the capacitive passenger detection system
for the front passenger seat indicates that
the passenger side frontal airbag must be
switched off by the electron ic control unit
(the
PASSENGER AIR BAG OFF light
<> page 150 and how they wo rk comes on
and stays on).
.&_ WARNING
Sitting in the wrong posi tion can inc rease
the risk of serious injury in crashes .
- To reduce the r is k of i njury when the air­
bags inflate, the driver and passengers
must always sit in an upright position,
must not lean against or place any part of their body too close to the area whe
re
the airbags a re located .
- Occupants who are unbelted, out of posi­
tion or too close to the airbag can be se­
rio us ly injured by an airbag as it unfolds
with great force in the blink of an eye

.&_ WARNING
--A child in a rearward-fac ing ch ild seat in -
stalled on the front passenger seat wi ll be
se riously in ju red and can be killed if t he
front ai rbag inflates - even w ith an Ad­
vanced A irbag System.
- The inflating airbag will h it the c hild seat
or infan t ca rrier with grea t for ce and will
smash the child sea t and chi ld against
the backrest, center armrest, door or
roof.
- Always install rear -fac ing ch ild seats on
the rear seat.
- If you m ust ins ta ll a rearw ard fac ing
chi ld 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
ately insta ll the rear-facing child seat in a
rear seat ing pos ition and have the airbag
system inspected by you r Audi dealer .
.&_ WARNING
= -
Objects between you and the airbag will
i nc rease the r is k of injury in a crash by in­
terfer ing with the way the a irbag unfolds
or by be ing p ushed in to you as the airbag
i nflates.
- Neve r hold things in yo ur hands or on
your lap when the veh icle is in use.
- Never transpo rt items on o r in t he a rea
of the front p assenger sea t. Objects
could move into the a rea of the front a ir­
bags du ring braking or other sudden ma ­
neuvers and become dangero us projec­
tiles that can cause ser ious personal in-
jury if the a irbags inf late. ..,.

adult is properly seated and restrained at
one of the rear seating positions.
- Have the airbag system inspected by
yo ur Audi dealer before transporting
anyone on the front passenger seat.
(D Tips
If the capacitive passenger detection sys ­
tem determines that the front passenger
seat is empty, the frontal airbag on the
passenger side will be turned off, and the
P ASS ENGER AIR B AG OFF light will stay
on.
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
& Maintenance book­
let under
AIRBAG REPLACEMENT RE­
CORD.
- For safety reasons in severe accidents,
the alternator and starter are separated from the veh icle battery with a pyrotech-
nic circuit inte rrupte r. .,.. •
