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, a lways:
• Adjust the dr iver's seat and steering wheel
properly ¢
page 166,
• Adjust the front passenger's seat properly
r=;page 72 ,
• Wear safety be lts properly
r=; page 178,
• Always properly use the proper child re-
stra int to protect children¢
page 205.
In a collision, airbags must inflate within the
blink of an eye and with considerable force .
The supplementa l airbags can cause injuries if
the dr iver or the front seat passenger is not
seated properly . Therefore in order to he lp the
a irbag to do its job, it is important, both as a
d river and as a passenge r to sit properly at all
times.
By keeping room between your body and the
steering wheel and the front of the passenger
compartment, the airbag ca n inflate fully and
comp letely and provide supp lemental p rotec­
tion in ce rtain frontal collisions¢

There is a lot that the driver and the passen­
gers can and must do to help the individua l
safety features ins talled in your A udi work to­
gether as a system.
Prope r seat ing pos ition is important so that
the front airbag on the driver s ide can do i ts
job. If yo u have a physical impa irment or con- dition that prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the peda ls , or if you
have concerns with regard to the function or
operation of the Advanced Airbag System,
please contact your author ized Audi dealer or
qualified workshop, or call Audi Customer Re­
lations at 1-800-822-2834 for poss ible modi­
fica tions to your ve hicle.
When the airbag system deploys, a gas gener ­
ator will f il l the a irbags, break open t he pad­
ded cove rs, and i nflate between the steer ing
whee l and the dr iver and between the instru­
ment pane l and the front passenger. The a ir­
bags will deflate immediately after dep loy­
ment so tha t the front occupants can see
t h ro ugh the windshie ld again witho ut inter­
ruption .
All of th is takes p lace in the b link o f an eye, so
fast that many peop le don't even realize tha t
the airbags have dep loyed. The airbags a lso
inflate with a great dea l of force and nothing
shou ld be in their way when they deploy.
Front a irbags in combination with properly
wor n safety belts slow down and lim it the oc ­
cupant's forward movement . T ogether they
help to prevent the drive r and front seat pas­
senger from hitting pa rts of the inside o f th e
vehicle 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 airbags wi ll not inflate in all fronta l
collisions . The t riggering of the airbag system
depends on the vehicle dece lerat ion rate
ca used by the co llision and registered by the
electron ic control unit. If th is rate is below
the reference value programmed into the con ­
t rol unit , the airbags will not be trigge red,
even though the car may be badly damaged as
a res ult of the co llision . Ve hicl e damage, re­
pair costs o r even the lack of ve hicle damage
is not necessari ly an indication of whe ther an
airbag shou ld inflate or not .
IJll-

Since the circums tances will vary considerab ly
between one collision and another , it is not
possible to define a range of veh icle speeds
that will cover every possible k ind and angle
of impact t hat w ill always t rig ger the a irbags .
Important factors include, for example, the
nature (hard or so ft) of the object which the
car h its, the ang le of impact, vehicle speed,
etc. The front airbags will a lso not inflate in
side or rear collisions, or in ro ll-overs .
Alw ays rememb er: Airbags will deploy only
once, and only in certa in kinds of co llisions.
Your safety belts are always there to offe r pro­
tect ion in those s ituations in which airbags
are 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 a irbag is
a supp lementary restraint and is not a s ubsti ­
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 175.
A WARNING
Sitting too close to the steer ing whee l or
instrument panel will dec rease the effec­
tiveness of the airbags and will inc rease
the risk of pe rsonal injury in a co llision .
- Never sit closer than 10 inches (2S cm)
to the stee ring wheel or instr ument pan­
el.
- If you cannot sit more than 10 inches
( 2 5 cm) from the steer ing whee l, investi­
ga te whethe r adaptive equipment may
be available to help you reach the pedals
and increase your seating distance from
the steering wheel.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, yo ur risk of inj ury 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 179, Safety belts.
-Always make certain that ch ild 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 back rest reclined .
- Always sit as far as possible from the
steer ing whee l or the instrument pane l
¢page 166.
-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 preven t serio us in ju ries to the legs
and h ips if the airbag infla tes.
- 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
sud den maneuve r. Obje cts near the air ­
bags can become projectiles and cause
in jur y when an airbag inflates.
A WARNING
Airbags that have de ployed in a crash must
be replaced.
- Use on ly orig inal equipment airbags ap­
proved by Aud i an d 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 .
- Never perm it salvaged or recycled air­
bags to be installed in your vehicle . •

- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and serious ly injure or even kill the
child -even with an Advanced Airbag
System .
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-se nsing mat and can
cause injury in a crash.

Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants.
Fig. 2 09 Locat ion of dr ive r air bag : in stee ring wheel
Fig. 2 10 Locat ion of front passenger's a irbag: in the in­
st rument panel
Your veh icle is equipped with an "Advanced
A irbag System" in complia nce w ith United
States Federal Motor Vehicle Safety Standard
( FM VSS) 208 as app licab le at the time your
veh icle was manufactured. The safety belts f
or the seats have "pretensioners" that help
to take slack out of t he belt system . The pre­
tens ioners are also act ivated by the electronic
control unit for the airbag system.
T he front safety be lts 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. 209 and the airbag for the
front passenger is in the instr ument panel
~ fig. 210 . The general locat ion of the a irbags
is marked "AIRBAG".
T here is a lot you nee d 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 you r passengers, especially in­
fants and small chi ldren.
_&. WARNING
Neve r rely on airbags alo ne for p rotection.
- E ven w hen they deploy, airbags provide
only supplement al pro tectio 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 properly res trained.
_&. WARNING
A pe rso n on the fron t 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 .
- A lthough t he Advanced Airbag System in
your veh icle is des igned to tur n off the
front passenge r airbag if an infant or a
small child is on the front passenger
seat, nobody can absolutely guarantee
-
that deployme nt under these special ..,

conditions is impossible in all conceiva­
ble s ituations that may happen during
the useful life of your vehicle.
- The Advanced A irbag System can deploy
in accordance with the "low risk" opt ion
under the U.S. Federa l Standard if a child
that is heavier than the typical one-year
old child is on the front passenger seat
and the other cond itions for airbag de­
ployment are met.
- Acc ident statist ics have shown that chil­
dre n are generally safe r in the rea r seat
area than in the front se ating posit io n.
- For their own safety , all children, espe­
ci ally 1 2 yea rs and younger, sho uld al­
w ays ride in the ba ck p roperly restrained
f or their age and size .
Advanced front airbag system
Your vehicle is equipped w it h a front Advanced
Ai rbag System in compl iance with United
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was
manufactured.
The front Advanced Airbag System supp le ­
ments the safety belts to provide addit iona l
protection for the driver's and front passeng­
er's heads and upper bodies in frontal crashes.
The airbags inflate only in frontal impacts
when the vehicle decele rat io n is high enough .
The front Advanced Airbag System for the
fro nt seat occupants is not a substitute for
your safety belts . Rather, it is part of the over­
all occupant rest raint system in your veh icle .
A lways remember that the airbag system can
only help to pro te ct you, if you a re s itting up­
right, wearing yo ur safe ty be lt and wearing i t
p roperly. This is why you and yo ur passenge rs
must always be properly restrained, not just
beca use the law requires you to be.
The Advanced Airbag System in your veh icle
h as been cer tified to meet the " low r is k" re ­
q uir ements for 3 and 6 year -o ld children on
the passenger side and very small adu lts on
the dr iver side. The low risk dep loyment crite­
ria are intended to he lp red uce the risk of in-
A irbag system 189
jury through interaction with the front ai rbag
that can occur, for examp le, by being too
close to the steering wheel and instr ument
panel when the airbag inflates.
In add ition, the system has been certi fied to
comply with the "s uppression" requirements
of the Sa fety 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
Standard
~ page 207, Child restraints and
Advanced Airbags .
"Suppression" requires the front a irbag on the
passenger s ide to be turned off if:
- a child up to abo ut one year o f age is re ­
strained on the front passenger seat in one
of the rear-fac ing or fo rward-facing infant
restrai nts listed in Federal Motor Vehicle
Safety Standa rd 208 with wh ich the Ad­
vanced Ai rbag System in your ve hicl e was
cert ified. Fo r a listing of the chi ld res traints
t h at were used to certify you r vehi cle's com­
pliance w it h t he US Sa fe ty Standard
~page 207,
-weigh t less than a thres ho ld level stored in
the control unit is de tected on the fron t pas ­
senger seat .
When a person is dete cted on t he front pas ­
senger se at, weigh ing more than the tota l
weight of a chi ld tha t is about 1 year old re ­
stra ined in one of the rear-facing or forward ­
facing infant restraints ( listed in Federal Mo­
tor Vehicle Safety Standard 208 w ith which
the Advanced Airbag System in you r vehicle
was certified), the front airbag on the passen­ ger side may or may not de ploy.
The
PASSENGER AIR BAG OFF light comes on
whe n the electro nic contro l unit detects a to­
ta l we ight on the front passe nger seat that re­
quires the front airbag to be tu rned off . If the
PASSENGER AIR BAG OFF light does no t
come on, the front ai rbag on t he passe nger
s ide has not been turned off by the cont ro l
u ni t an d can dep loy if t he con trol un it senses
an impact that meets the cond itions stored i n
its memory . ..,. •
•

190 Airbag sys tem
If the tota l weight on the front passenger
seat is more than that of a typical 1 year-o ld,
but less than the weight of a small adu lt, the
front airbag on the passenger side may deploy (the
PA SSEN GER AIR BAG OFF light 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 safety seats listed
¢ page 207),
-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.
The front a irbag on the passenger side may
not deploy (the PAS SENGER AIR BAG OFF
light does not ill uminate and stay lit) if:
- a small adu lt o r teenager is o n the front pas­
senger seat
- a passenger who is not sitt ing upright w ith
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 passenge r seat .
I f the front passenge r airbag deploys, the
F ederal Standa rd requires the airbag to meet
the " low ris k'' deployment criteria to help re ­
duce the risk of inj ury 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 195
Alway s remember : Even though yo ur 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, a lways wear safety belts prope rly. -
If you are unrestrained, leaning forward,
sitt ing s ideways or o ut of pos ition in any
way, your risk of injury is muc h higher.
- You will a lso receive serious injuries and
could even be killed if you are up aga inst
the airbag or too close to it when it in­
f lates -even w it h an Advanced A irbag
¢page 184.
A WARNING "---
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be serious ly inju red and ca n be killed if
the front airbag infla tes -even with an Ad­
vanced A irbag System.
- Al tho ugh t he Advanced Airbag Sys tem in
your veh icle is designed to turn off the
front airbag when a rearward -facing
child restraint has been insta lled 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 i nfant carrier with great
force and will smash the child safety seat
a nd child aga inst the bac krest, center
armrest, doo r, or roof.
- Always install rea rward-facing ch ild re­
s traints on the rear seat.
- If you must ins tall a rearwa rd fac ing
child safety seat on the fro nt 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 the rear-facing chi ld
safety seat in a rear seating position and
have the airbag system inspected by your
author ized Audi dealer.
A WARNING
-If, in except ional circumstances, you must
i nstall a forward-facing child restraint on
the front passenge r's seat:
II--

-Always make sure the forward-facing
seat 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 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 fo rward-facing child restraint . The
b ackres t m ust be adjus ted to an upr ight
posit ion.
- Make su re that the
PASSENGER AIR BAG
OFF
light comes on and s tays 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 mat, sensors, wiring, brack­
ets, and more . The function of the system in
the front passenger seat is checked by the
e lectronic control un it when the ignit ion is on .
The control un it mon itors the Advanced Air ­
bag Sys tem and turn s the a irbag in dica tor
light on when a ma lfunction in t he system
components is detected . The function of the
airbag indicator light is described in greater
deta il below. Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you must take care to
prevent it from being damaged . Damage to
the seat may p revent the Advanced A irbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag System
consists of the following:
- Crash sensors in the front of the veh icle that
measu re ve hicle accelera tion/decele ra ti on
to provide inform ation to the Advanced Air ­
bag System about the severity of the crash.

-Improper repair or disassembly of the
front passenger and driver seat will pre­
vent the Advanced Airbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
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 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 Adv a 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, regard less of safety
be lt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amo unt programmed in the electronic control
un it. The front airbag on the passenger side
w ill 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
recog nized on the seat . The
PASSENGER AIR

More important things to know about
front airbags
F ig. 2 11 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfo ld properly and pro ­
vide supplemental protection in a fronta l col­
l ision.
A irba g sy stem 193
The front airbags are designed to provide ad ­
ditional protection for the chest and face of
the driver and the front seat passenger when:
- safety belts are worn properly
- t he seats have bee n positioned so that the
occ upan t is properly seated as far as poss i­
b le from the airbag
- and the head restraints have been properly
adj usted
Because airbags inflate in the blink of an eye
with great force, t hings you have on your lap
or have placed on the seat co uld become dan­
gerous projecti les, and be p ushed in to you if
the a irbag inf lates.
When an airbag deploys, fine dust is re leased.
T his is no rma l and is not caused by a fi re in
the vehi cle. This dust is made up mos tly of a
powder used to lub ricate the airbags as they
deploy. It could irritate skin.
It is important to remembe r that wh ile the
s u pplementa l airbag system is designed to re­
duce the like lihood o f serious injuries, other
injuries, for example swelling, bruising and
minor abrasions, can a lso happen when air ­
bags inflate . A irbags do not protect the arms
or the lower parts of the body. Front airbags
supplement the th ree-point safety belts only
i n some frontal co llisions in which the vehicle
deceleration is high enough to deploy the air­
bags.
Front a irbags will not deploy :
-if the ignition is sw itched off when a crash
occurs
- in side collisions
- in rear-end co llisions
- in rollovers
- when the crash dece leration meas ured by
the air bag system is less than the minimum
threshold needed for airbag deployment as
reg istered by the electronic cont ro l unit
The front passenger airbag also will not
deploy:
- when the front passenger seat is not occu-
pied ..,.
