possible to define a range of vehicle spee ds
that will cover every possible kind and angle
of impact that will always trigger the a irbags .
Important fact ors 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 .
Alw ay s 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 ituation s 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 veh icle af ­
ter the first co llision.
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 113 .
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 personal injury in a co llision .
- Never sit closer than
10 inches (25 cm)
to the steering 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 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 r isk of injury when an air ­
bag inflates, a lways wear safety belts
properly ¢

-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 104.
-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 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 area of the s ide a irbag or
the front a irbag du ring bra king or in a
sudde n 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 trained
technician who has the necessary too ls
and d iagnost ic equipment to properly re­
place any airbag in your vehicle and as­
sure system effectiveness in a crash .

Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants.
F ig . 131 Location of driver airbag: in steer ing whee l
Fig. 132 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 safe ty belts
for the front seats have "pretensioners" that
he lp to take slack out of the belt system. The
pretensioners are also activated by the elec­
tronic control unit for the airbag system.
The front safety be lts a lso have load limiters
to help reduce the forces applied to the body
i n a crash.
The airbag fo r the driver is in t he s teer ing
wheel hub¢
fig. 131 and the airbag for the front passenger is in the
instrument panel
¢
fig. 132 . The general location of the airbags
is marked "AIRBAG".
T here is a lot you need to know about the a ir­
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 the owner's literature.
Please be sure to heed the WARNINGS - they
are extremely important for your safety and
the safety of you r passengers, especially in­
fants and small children.
_&. WARNING
Neve r rely on airbags a lone for p rotection.
- Even when they deploy, airbags provide
only supplemental protect ion.
- Ai rbag work most effectively when used
with properly worn safety belts.
- Therefore, always wear your safety belts
a nd make sure that eve rybody in your ve­
h icle is p roperly restrained.
_&. WARNING
=
A pe rson on the front passenger seat, es-
pe cial ly infants and sma ll children, w ill re­
ce ive ser io us in ju ries and can even be kil­
l ed by being too close to the airbag when
it inflates .
- Altho ugh the Advanced Airbag Sys tem in
your vehicle is designed to tur n off the
front passenger airbag if a n in fant or a
sma ll child is on the front passenger
seat, nobody can absolutely guarantee
that deployment under these special
conditions is imposs ible in all conceiva­
b le si tua tions that may happen during
the useful life of your v ehicle.
- The Advanced Airbag System can dep loy
i n acco rdance with the "low risk" option
unde r the U.S. Fede ral Standa rd if a child
t hat is heav ie r th an the typical o ne-year
old ch ild is on the front passenger seat
and the other conditions for ai rbag de ­
p loyment are met .

-Accident statistics have shown that chil­
dren are generally safer in the rear seat
area than in the front seating posit ion.
- For their own safety, all children, espe­
cially 12 years and younger, sho uld al­
ways ride in the back properly restrained
for their age and size.
Advanced front airbag system
Your veh icle is equipped w ith a front Advanced
A irbag System in compliance with Un ited
States Federal Motor Vehicle Safety S tanda rd
208 as applicab le a t the time your vehicle was
manufac tured .
The front Advanced Airbag System supple­ ments the safety belts to provide add it iona l
p rotection fo r the driver's and fron t passeng­
e r' s heads and upper bodies in fronta l crashes.
The airbags inflate only in frontal impacts
when the vehicle dece leration is high enough .
The fron t Advanced A irbag Sys tem for the
front seat occ upants is no t a substi tute for
your safety bel ts. Rather, it is part of the over ­
a ll occupa nt restraint system in your vehicle.
A lways remember that the airbag system can
only help to protect you, if you are s itting up­
right, wearing your safety belt and wearing it
properly . This is w hy you and your passenge rs
must always be properly restrai ned, not just
because the law requires you to be .
The Advanced Airbag System i n 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 passenger s ide and very small adu lts on
the dr iver side. The low ris k dep loymen t cr ite­
ria are intended to he lp red uce the risk of i n­
j ury thro ugh in teraction with the front airbag
that can occ ur, fo r example, by being too
close to the steering whee l and instrument
panel when the airbag inflates.
I n addition, the sys tem has been certif ied to
comp ly with the "suppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are restra ined on the front passenger
A irbag system 127
seat in child rest raints that are listed in the
Standard
¢ page 145 .
"Supp ress ion" requi res the fron t airbag on t he
passenge r sid e to be turned off if:
- a child up to abo ut one year of age is re­
strained on the front passenger seat in one
of t he rear-fa cing o r fo rward -f a cing infan t
res traints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad ­
vanced Airbag System in your ve hicle was
cert ified. For a listing o f the chi ld restraints
that were used to certify your vehicle's com­
pliance w ith the US Safety Standard
¢page 145,
- weight less than a thresho ld level stored in
the control unit is detected on the front pas­
senge r seat.
When a person is detected on the front pas­
senger seat, weighing more than the total
weight of a chi ld that is about 1 year old re­
stra ined in one of the rear -fac ing or forward ­
facing infant restraints ( listed in Fede ral Mo­
tor Vehicle Safety Standard 208 with whic h
t h e Advanced A irbag Sys tem in yo ur vehicle
was certified), the fron t airbag on the passen­
ger side may or may not dep loy .
T he
PASSENGER AIR BAG OFF lig ht comes o n
whe n the elect ro nic cont ro l unit de tects a to ­
ta l we igh t on the front p assenger sea t that re­
quires the front airbag to be t urned off .
If the
PASSENGER AIR BAG OFF light does not
come on, the front ai rbag on the passenger
s ide has not been t urned off by the contro l
u nit and can dep loy if the control un it senses
an impact that meets the cond itions stored i n
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 we ight of a small adu lt, the
front a irbag on t he passenger side may dep loy
(the
PASSENGER AIR BAG OFF light does not
come on) .
For example, the airbag may deploy if:

on the front passenger seat.
I f the front passenger airbag is turned
off , the
PASSEN GER AIR BA G OFF light in the cen ter
of the instrument pane l will come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PA SSENGER AIR BAG OFF
light does not illuminate and stay lit) if:
- a small adu lt or teenager is o n the front pas­
senger seat
- a passenger who is not sitt ing upr ight w ith
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the sea t is on the front passenger seat.
I f 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 in jury through in terac tion
with the airbag. " Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the e lectronic contro l
un it
q page 133.
Alwa ys remember: Even tho ugh you r vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat. Please be sure to read the impo r­
tant information in the sect ions that follow
and be sure to heed a ll of the WARNINGS .
A WARNING
To reduce the risk of injury when an airbag
inflates, a lways wear safety belts prope rly .
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of injury is much higher.
- You w ill also receive serio us in juries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in­
fla tes - even with an Adv ance d Airbag
qpage 122.
A WARNING
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be serious ly injured and can be killed if
the front airbag inflates - even with an Ad­
van ced A irbag System.
- Altho ugh the Advanced Airbag System in
your veh icle is designed to tur n
off the
front air bag when a rearward-facing
child res traint has been instal le d 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
safety seat or infant carrier with great
force and will smash the child safety seat
and child aga inst the backrest, center
armrest, doo r, or roof.
- Always install rearward-facing ch ild re­
straints in the back seat.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptiona l circumstan­
ces and t he
PASSENGER AIR BAG OFF
light does not come on and s tay on, im­
mediately inst all the rear-fac ing c hild
safety seat in a rear seating position and
have the air bag system inspected by your
author ized Audi dealer .
A_ WARNING
If, in exceptiona l circumstances, you m ust
i nsta ll 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 fo rward-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 justmen t range, as fa r away from
the airbag as possible, before ins talling

the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the
PASSENG ER AI R BA G
OFF
light comes on and stays on all the
t ime whenever the ignition is switched
on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing ma t, sensors, wiring, brack­
ets, and mo re. The function of the system in
the front passenger seat is checked by the
e lectronic control unit when the ignition is on .
The control unit monitors the Advanced Air­ bag System and turns the airbag indicator
light on when a malfunction in the system
components is detected. The function of the
airbag ind icator light is described in greater
deta il below. Because the front passenger
seat contains impo rtant parts of the Ad­
vanced A irbag System, you m ust take care to
p revent 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 Advanc ed Airbag Syst em
con sis ts o f th e following :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration
to provide information to the Advanced Air­ bag System about the severity of the crash.
-An electronic control unit, with integrated
crash sensors for front and side impacts .
The cont ro l unit "decides" whether to fire
the front airbags based on the information r eceived from the c rash sensors. The control
unit a lso "dec ides" whet her the safety be lt
pretensione rs should be activated.
- An Advanced Airbag with gas generator for
the d river ins ide the steer ing whee l hub.
- An Advanced Airbag with gas generator in­
s ide t he instr ument pane l for the front pas­
senger.
A irbag system 129
- A weight-sensing mat under the upho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat .
The informat ion reg istered is sent continu­
ously to the electron ic control unit to regu­
late deployment of the front Advanced Air­
bag on the passenger side.
- An airbag monitoring system and ind icator
light in the instrument cluster
¢page 133.
-The PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instru­
ment panel
c:::> page 133, fig . 134 and tells
you when the front Advanced Airbag on the passe nger side has been tu rned off.
- A senso r below the safety belt latch fo r the
front seat passenger to measure the tension
on the safety be lt. T he ten sion on the safety
be lt and the weight regis tered by the
weight -sensing mat he lp the control unit
"decide" whether the front airbag fo r the
front passenger seat should be turned off or not

know.
-A sensor in the safety belt latch for the driv­
er and for the front seat passenger that
senses whether that safety belt is latched or

A WARNING
D amage to the front passenger seat can
p revent the front airbag from wor king
properly.
- Imp roper repai r or d isassembly of the
fr on t passenge r and dr iver seat will pre­
vent the Advanced Airbag System from
functioning p roperly.
- Repairs to the front passenger seat must
be pe rformed by qualified and p roperly
trained workshop personne l.
- Never remove the front passenger or driver seat from the vehicle .
- Never remove the upho lstery from the
front passenger seat .
- Never disassemble or remove p arts from
-
the sea t 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-sensing mat and send the
wrong information 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 .
- Never use cushions, pillows, blankets or
similar items on the front passenger
seat. The additional padding will prevent
the weight-sensing mat in the seat from
accurately registering the child restraint
or person on the seat and prevent the
Advanced Airbag System from function­
ing properly.
- 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 authorized Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side airbags supplement the protection of­
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help reduce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the impor­
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adva need Airbag System
and the activation of the safety belt preten­
sioners depend on the deceleration measured
by the crash sensors and registered by the
electronic control unit. Crash severity depends
on speed and deceleration as well as the mass
and stiffness of the vehicle or object involved
in the crash.
When the electronic control unit registers a
low severity crash and the safety belt is being
used , the airbag will not deploy. If the safety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat­
er time in the crash sequence.
If the electronic control unit registers a crash
of medium severity, the first stage of the air­
bag deploys followed by the second stage at a
much later time in the crash sequence - re­
gardless of whether the safety belt is being
used or not . In higher severity crashes as reg ­
istered by the electronic control unit, both the
first and second stages deploy almost at the same time.
On the passenger side, regardless of safety
belt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amount programmed in the electronic control
unit. The front airbag on the passenger side
will also be turned off if one of the child safe­
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recognized on the seat. The
PASSENGER AIR
BAG OFF
light comes on and stays on to tell
you when the front Advanced Airbag on the passenger side has been turned off ..,_

More important things to know about
front airbags
F ig. 133 Inflated front a irbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfold properly and pro­
vide supp lemental protection in a fronta l co l­
lision .
The front a irbags are designed to provide ad­
d itiona l protection for the chest and face of
the dr iver and 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 possi­
ble from the a irbag,
- and the head restraints have been proper ly
adjusted .
Because airbags i nflate in the blink of an eye
with great force, things you have on your lap or have placed on the seat could become dan­
gerous projectiles, and be pushed into you if
the airbag inflates.
A irba g sy stem 131
When an airbag deploys, fine dust is re leased.
This is norma l and is not caused by a fire in
the vehicle . This dust is made up mostly of a
powder used to lubricate the airbags as they
deploy. It could irritate skin .
It is important to remember that whi le the
supplementa l airbag system is designed to re­
duce the like lihood of serious injuries, other
injur ies, for example swelling, bruising and
minor abras ions, can also happen when air­
bags i nflate. A irbags do not protect the arms
or the lower parts of the body . Front a irbags
supplement the th ree -po in t safety belts only
in some fronta l co llisions in which the vehicle
deceleration is high enough to deploy the air­
bags .
Front airbags will not deploy :
-if the ignition is sw itched off when a crash
o ccu rs,
- in side co llisions,
- in rear-end collisions,
- in rollovers,
- when the crash dece leration measured by
the airbag system is less than the minimum
threshold needed for a irbag deployment as
reg istered by the electron ic contro l unit .
The f ront pa ssen ger airbag als o will no t
deplo y:
- when the front passenger seat is not occu­
pied,
- when the weight on the front passenger
seat as sensed by the Advanced Airbag Sys­
tem ind icates that the front a irbag on the
passenger side has to be tu rned off by the
electronic contro l un it (the
PASSENGER AIR
BA G OFF
light comes on and stays o n).
.&, WARNING
Sitting in t he wrong pos ition can increase
the risk of serious injury in crashes.
- T o reduce the risk of injury when the air­
bags inflate, the driver and passenge rs
m ust always s it in an upright position,
m ust not lean against or place any part

132 Airbag system
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
r=> page 123 .
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
neuvers 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 cup holders, 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 brak ing 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
-T he 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.
