Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job , occupants must al­
ways properly wear their safety belts and be
in a proper seating position.
F or your safety and the safety of your passen­
gers, before driving off, always:
• Adjust the driver's seat and steering wheel
properly ¢
page 129,
• Adjust the front passenger's seat properly
¢ page 59,
• Wear safety be lts properly ¢ page 141,
• Always properly use the proper child re-
straint to protect children¢
page 167.
In a collision airbags must inflate within the
blink of an eye and with considerable force.
The supplemental airbags can cause injuries if
the driver or the front seat passenger is not
seated properly . Therefore in order to help the
a ir bag to do its job, it is important, both as a
d river and as a passenger to sit prope rly at all
times.
By keeping room between your body and the
steering wheel and the front of the passenger
compartment, the airbag can inflate fully and
comp letely and provide supplemental protec­
tion in ce rtain frontal collisions

There is a lot that the driver and the passen­
ge rs can and must do to help the individual
safety features installed in your A udi work to­
gether as a system.
Proper seating pos ition is important so that
the front airbag on the driver side can do its
job. If you have a physical impairment or con- dition that
prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the pedals , spec ial
modifications to your vehicle may be necessa­
ry.
Contact your authorized Audi dea ler, or call
Audi C ustomer Re lations at 1-800-822-2834.
When the airbag system dep loys , a gas gener­
ator will f ill the airbags, break open the pad­
ded covers, and inflate between the steering
whee l and the dr iver and between the instru­
ment panel and the front passenger. The air­
bags will deflate immediately after deploy­
ment so that the front occupants can see
th rough the windshield aga in without inter­
ruption .
All of th is takes place in the blink of an eye , so
fast that many people don't even realize that
the a irbags have deployed . The airbags also
inflate with a great deal of force and nothing
shou ld be in their way when they deploy.
Front airbags in combination with properly
worn safety belts slow down and limit the oc­
cupant's forward movement. Together they
help to prevent the driver and front seat pas­
senger from hitting parts of the inside the ve­
hicle while reducing the forces acting on the
occupant dur ing the crash. In this way they
help to reduce the risk of injury to the head
and upper body in the crash . A irbags do not
protect the arms or the lower parts of the
body.
Both front a irbags w ill not inflate in all fronta l
collisions . The triggering of the airbag system
depends on the vehicle dece lerat ion rate
caused by the collision and registered by the
electron ic control unit. If this rate is below
the reference value programmed into the con­
trol unit, the airbags will not be trigge red ,
even though the car may be bad ly damaged as
a resu lt of the co llision . Vehicle damage, re­
pair costs or even the lack of veh icle damage
is no t necessarily an indication of whether an
airbag should inflate or not .
It is not possib le to define a range of vehicle
speeds that w ill cover every possib le kind and .,.

angle of impact that will always trigger the
airbags, since the circumstances will vary con­
siderably between one collision and another.
Important factors include, for example, the nature (hard or soft) of the object which the
car hits, the angle of impact, vehicle speed,
etc. The front airbags will also not inflate in
side or rear collisions, or in ro ll-overs .
Alwa ys rem ember : Airbags will deploy only
once, and only in certa in kinds of collisions .
Your safety belts are always there to offer pro­
tection in those s ituations in which airbags
are not supposed to deploy , or when they have
a lready deployed ; fo r example , when yo ur ve­
h icle strikes or is struck by another after the
first collision .
This is just one of the reasons why an a irbag is
a supplementary restra int and is not a s ubst i­
tute for a safety belt . The airbag system
works most effectively when used with the
safety belts. Therefore, always properly wear
your safety belts
¢ page 138.
A WARNING
Sitting too close to the steer ing wheel or
instrument panel will decrease the effec­
tiveness of the airbags and will increase
the risk of pe rsonal injury in a co llision .
- Never sit closer than
10 inches (25 cm)
to the stee ring wheel or instrument pan­
el.
- If you cannot sit more than
10 i nches
(25 cm) from the steer ing whee l, investi­
gate whether adaptive equipment may
be available to help you reach the pedals
and increase your seating dis tance from
the steering wheel.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way, yo ur risk of inj ury is much highe r.
- You w il l also receive serio us inju ries and
cou ld even be killed if you are up against
the airbag or too close to it when it in ­
flates -even with an Advanced Airbag.
- To reduce the r isk o f injury when an air ­
bag inflates, a lways wear safety belts
proper ly ¢
page 141, Safety belts .
Airbag system 147
-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 129.
-Always sit upright with your back against
the backrest of your seat.
- Never p lace your feet on the instrument
panel or on the seat. Always keep both
feet on the f loor in front of the seat to
he lp prevent serio us in juries to the legs
a nd h ips if the airbag inflates.
- Never recline the front passenger 's seat
to tra nsport objects. Items can a lso
move i nto the area of the s ide a irbag or
the front a irbag du ring bra king or in a
sud den maneuve r. Obje cts ne ar the air­
bags can become projectiles and cause
injury when an airbag inflates.
_&. WARNING ~
A irbags that have de ployed in a crash must
be replaced.
- Use on ly original equipment airbags ap­
proved by Audi and installed by a trai ned
technician who has the necessary too ls
and d iagnost ic equipment to properly re­
place any airbag in your vehicle and as­
sure system effectiveness in a crash .
- Never perm it salvaged or recycled air­
bags to be installed in your vehicle .

148 Airbag sys tem
Even tho ugh your vehicle is equip ped with an
Advanced Airbag System , make certain that
a ll c hildren, especially those 12 years and
younge r, a lways ride in the back seat properly
restra ined for their age and size. The airbag
on the passenger side makes the front seat a potentially dangerous place for a ch ild to r ide.
The front seat is not the safest place for a
child in a fo rward-facing ch ild safety seat. It
can be a very dangerous place for a n infant or
a child in a rea rward-facing seat.
The Advanced Airbag System i n your veh icle
has been certified to comp ly with the Requ ire­
men ts of Uni ted Sta tes Federa l Mo tor Veh icle
Safety Standard 208 as applicable at the time
your veh icle was manufactured.
The Standard requires the front a irbag on t he
passenger side to be turned off ("sup­
pressed") if a ch ild up to about one year of
age restrained in one of the rear -facing o r for­
ward -facing infant restraints listed i n Federal
Motor Vehicle Safety Standard 208 with which
the Advanced A irbag System in your vehicle
was certified has been installed o n the front
passenger seat . For a listing of the child re ­
strai nts t hat we re used to certify compliance
with the US Safety Standard
r=vpage 169.
The PASSENGER AIR BAG OFF light in the in­
strument panel te lls you when the front Ad­
vanced A irbag on the passenger side has been
turned off by the e lectronic control unit.
Each t ime you turn on the ignition, the
PAS ­
SENGER AIR BA G OFF
light will come on for a
few seconds a nd:
- will stay on if the front passenger seat is not
occupied,
- wi ll stay on if there is a small child or child
restraint on the front passenger seat,
- wi ll go off if the front passenger seat is oc ­
cupied by an adult as registered by the
weight-sensing mat
r=v page 156, Monitor­
ing the Advanced Airbag System .
The PASSENGER AIR BAG OFF light comes on
when the control un it detects a total weight
on the front passenger seat that requ ires the
fro nt airbag to be turned off.
If the total weight on the front passenge r
seat is more than that of a typica l 1 year -old
c hil d but less than the weight o f a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
li ght does not come on). If the PASSENGER
AIR BAG OFF
light does not come on , the
front a irbag on the passeng er side has not
been turned off by the elec troni c con trol unit
and can deploy if the control uni t se nses an
impact that meets the cond itions stored in its
memo ry .
For example, the airbag may deploy if:
- a small ch ild that is heav ier t han a typical 1
year-old ch ild is on the front passenger seat
( r egard less of whethe r the child is i n one of
t he child safety seats listed
r=v page 169), or
- a child who has outgrown ch ild restraints is
on t he front passenge r seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instr ument cluster and stays on.
The front airbag on the passenger s ide may
not deploy (the PASSENGER AIR BAG OFF
li gh t does not illum inate and stay lit) even if a
small adult o r teenager, or a passenger who is
not sitt ing up rig ht w ith their back against a
non- recl ined ba ck res t w it h thei r feet on the
vehicle f loor i n front of the sea t is on the front
passenger seat
r=v page 129 , Proper seating
position for the driver.
If t he fron t passenger a irbag dep loys, the
F ede ra l Standard req uires the airbag to meet
t h e "low risk" dep loyment criteria to red uce
t h e risk of injury t hrough interactio n wit h the
airbag. "Low risk" dep loyment occ urs in those
crashes that take place at lower dece lerat ions
as defined in the electronic control unit
r=v page 157, PASSENGER AIR BAG OFF light .
Always remember, a child safety seat or infant
carr ier installed on the front seat may be
struck and knocked out of posit ion by the rap­
idly inflat ing passenger 's airbag in a fronta l
collision . T he a irbag could great ly reduce the
effectiveness of the ch ild restra int and even
seriously injure t he ch ild dur ing inflation .

For this reason, and because the back seat is
the safest place for children - when properly restrained according to their age and size - we
strongly recommend that children always sit in the back seat
Q page 167, Child Safety.
A WARNING
-
A child in a rearward-facing child safety seat installed on the front passenger seat
w ill be seriously injured and can be k illed if
the front a irbag inflates - even with an Ad­
vanced Airbag System.
- T he inflating a irbag w ill hit the child
safety seat or infant carrier w ith great
force and w ill smash the ch ild safety sea t
and child against the backrest, cente r
armrest, door or roof .
- Always install rear -facing child safety
seats on the rear seat.
- If you mus t inst all a rearward facing
child safety seat on the front passenger
seat beca use of exceptional circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on , im­
med iately install the rear-facing child
safety seat in a rear seating posit ion and
have the a irbag system inspected by your
authorized Aud i dealer .
- Forward-fac ing ch ild safety seats instal­
led on the front passenger's seat may in­
terfe re with the deployment of the air­
bag and cause se rious personal injury to
the ch ild.
A WARNING
If, in exceptional c irc umstances, you mus t
install a forwa rd-facing child restra int on
the front passenger's seat:
- Alw ays make sure the forw ard -fac ing
sea t has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Never put the forward -facing child re ­
straint up aga inst or very near the instru­
ment pane l.
- Always move the passenger seat into its
rearmost position in the seat's fore and
A irbag system 149
aft ad justment range, as far away from
the airbag as possible before installing
the forward-fac ing ch ild restraint. The
backrest must be adj usted to an upright
position .
- Make sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the
time wheneve r the ignit ion is switched
on.
A WARNING
T o reduce the risk of ser ious injury, make
su re that the
PASSENGER AIR BAG OFF
light w ill be displayed whenever a child re­
straint is installed on the front passenger
seat and the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light
does not s tay on, per form the checks de ­
scribed
Q page 156, Monitoring the Ad ­
vanced Airbag System.
- Take the chi ld restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN ­
GER AIR BAG Off light does not stay on.
- Have the airbag system inspected by
your author ized Audi dealer immed iate­
ly .
-Always carefu lly follow instr uctions from
child restraint manufacturers when in­
stall ing ch ild restra ints .
A WARNING
If, in except iona l circumstances, you must
install a forward or rearward-facing child
restra int on the front passenger's seat :
- Improper instal lation of ch ild restraints
can reduce their effectiveness o r even
prevent them from providing any protec­
tion.
- An improper ly installed ch ild restra int
can interfere with the airbag as it de­
ploys and seriously i njure o r even kill the
child -even with an Advanced Airbag
System.
- Always carefu lly follow the manufact ur­
er 's ins tructions p rov ided with the ch ild
safety seat or carrier . •

Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants.
F ig . 153 Location of driver airbag: in steer ing whee l
Fig. 15 4 Location of front passenger's airbag: in the in ­
strument panel
Your veh icle is equipped with an "Advanced
A irbag System" in compliance with United
States Federal Motor Vehicle Safety Standard ( FM VSS) 208 as app licab le at the time your
ve hicl e was manufac tured. The system senses
the position of the front seats and controls
front airbag inflation with a valve, depending
on the distance between the respect ive seat
and the steering wheel or instrument panel.
The safety belts for the seats have "preten­
sioners" that he lp to take slack out of the belt
system . The pretensioners a re also activated
by the electron ic cont ro l unit for the ai rbag
system. T
he front safety belts also have load limiters
to help reduce the forces applied to the body
i n a crash .
T he airbag for the drive r is in the stee ring
whee l hub¢
fig. 153 and the airbag for the
front passenger is in the instrument panel
~ fig. 154 . The general locat ion of the a irbags
is marked "AIRBAG".
T here is a lot you need to know about the ai r­
bags in your vehicle. We urge you to read the
detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature.
P lease be sure to heed the WARNINGS -they
are extremely importa nt for your safety and
the safety of your passengers, especially in­
fants and small chi ldren.
_&. WARNING
Neve r rely on airbags alone for p rotection.
- Even w hen they deploy, airbags provide
only s upplement al pro te ctio n.
- Airbag work most effect ive ly when used
with p roperly wor n safety bel ts.
- Therefore, always wea r you r safety belts
a nd make sure tha t eve rybody in your ve­
h icle is p roperly res trained.
_&. WARNING
A pe rson on the front passenger seat, es­
pe cial ly infa nts and sm all ch ildren, w ill re­
ceive serio us inju ries and can even be kil­
l ed by being too close to the airbag when
it inflates .
- Although t he Advanced Airbag System in
your veh icle is designed to tur n off the
front passenger airbag if an infant or a
small child is on the front passe nger
seat, nobody can absolutely guarantee
that deployment under these special
conditions is imposs ible in all conceiva­
b le sit uat ions that may happen during
the useful life of your vehicle.
- The Advanced Airbag System can dep loy
i n acco rdance with the "low risk" option
unde r the U.S . Feder al Standard if a child
that is heav ie r than the typical one -year
-
.

old chi ld is on the front passenger seat
and the other cond itions 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 posit ion.
- 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 w ith a front Advanced
Airbag System in compliance with Un ited
States Federal Motor Vehicle Safety Standard
208 as app licable at the time yo ur vehicle was
manufactured .
The front Advanced Airbag System supple­ ments the safety belts to provide add it io na l
protection fo r the d river's and fron t passeng­
e r' s heads and upper bodies in fronta l crashes.
The airbags inflate only in frontal impacts
when th e vehicle dece le rat ion is high enough .
The front Advanced Airbag Sys tem for the
front seat occupants is not a substit ute for
your safety belts. Rather, it is part of the over­
all occupant restraint system in your vehicle.
A lways remember that the ai rbag system can
only help to protect you, if you are sitting up­
right, wearing you r safety belt and wearing it
properly . This is why you and you r passengers
must always be properly restrained, not just
because the law requires you to be.
T he Advanced Airbag System in your veh icle
has been cert ified to meet the "low risk " re ­
qu irements for 3 and 6 year-o ld children on
the passenge r side and very small adu lts on
the dr iver side . The low risk dep loymen t crite­
ria are intended to he lp red uce the risk of i n­
jury through interaction with the front airbag
that can occ ur, for example , by being too
close to the steer ing whee l and instrument
panel when the airbag inflates.
I n addition, the system has been certif ied to
comp ly with the "suppression" requirements
A irbag system 15 1
of the Safe ty Standa rd, 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 Standa rd
¢ page 169 , Child restraints and
Advanced Airbags .
"Suppression" requires the front a irbag on the
passenger side to be turned off if:
- a child up to abo ut one year o f age is re ­
strained on the front passenger seat i n one
of the rear-fac ing or forward-facing infant
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your ve hicle was
cert ified . Fo r a listing o f the child restraints

senge r seat.
When a person is detected on the front pas­
senger seat, weighing more than the total
weight of a ch ild tha t is abou t 1 year old re ­
stra ined in one of the rear -faci ng or forward ­
f acing infa nt res traints ( listed in Fede ral Mo­
tor Vehicle Safety Standard 208 w it h which
the Advanced Airbag System in yo ur 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 elect ronic contro l unit detects a to­
ta l we ight on the front passenger seat that re­
quires the front airbag to be tu rned off. If the

come on, the front ai rbag on the passenger
s ide has not been turned off by the cont ro l
unit and ca n dep loy if t he control un it senses
an impact that meets the cond itions stored i n
its memory.
If the total weig ht on the front passenge r
seat is more than that of a typical 1 yea r-o ld ,
bu t less than the we igh t of a small ad ult, t he

152 Airbag sys te m
For exa mpl e, the air b ag ma y depl oy if:
- a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whe ther the child is in one of
the chi ld safety seats listed
¢ page 169),
-a ch ild who has outgrown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PA SSENGER AIR BAG OFF light in the cente r
of the instrument panel w ill come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PAS SENGER AIR BAG OFF
light does not illuminate and stay lit) if:
- a small adult or teenager is on the front pas­
senger seat
- a passenger who is not sitt ing upright wit h
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the seat is on the front passenger seat.
If the front passenger airbag deploys, the Federal Standard requires the airbag to meet
the "low risk" deployment criteria to help re­
d uce the risk of inju ry through interaction
with the airbag. " Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the e lectronic control
un it.

Alw ays remember : Even though 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 impor­
tant information in the sect ions that follow
and be sure to heed all of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag
inf lates, always wear safety belts properly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of in jury is much higher.
- You w ill also receive serious injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in- f
lates - even with an Advanced A irbag
¢page 146.
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
vanced A irbag System.
- Although 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 during the usefu l life of your
veh icle.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child aga inst the backrest, center
armrest, door, 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 the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately insta ll th e rear-fac ing ch ild
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer .
A WARNING
If, in exceptional circumstances, you m ust
insta 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 forward-facing child re­
straint up against or very near the instru- ment panel.
~

-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 insta lling
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
o n.
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-sens ing 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 .
