Airbag system
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 always properly wear their
safety belts and be in a proper seating position.
For your safety and the safety of your passengers, before
driving off, always:
- Adjust the driver's seat and steering wheel properly
=>
page 178,
- Adjust the front passenger's seat properly=> page 78,
-Wear safety belts properly=> page 192,
-Always properly use the proper child restraint to protect
children=>
page 221.
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 airbag to do its job, it is important, both as a driver
and as a passenger 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 can inflate fully and
completely and provide supplemental protection in certain frontal
collisions =:,
page 178, "Proper occupant seating positions" . For
details on the operation of the seat adjustment controls=>
page 78.
It's especially important that children are properly restrained
=:,
page 221.
Controls and equip­ ment Safety first Vehicle operation
There
is a lot that the driver and the passengers can and must do to
help the individual safety features installed in your Audi work
together as a system .
Proper seating position is important so that the front airbag on the
driver side can do its job. If you have a physical impairment or condi­
tion that prevents you from sitting properly on the driver seat with
the safety belt properly fastened and reaching the pedals, special
modifications to your vehicle may be necessary .
Contact your authorized Audi dealer, or call Audi Customer Relations
at 1-800-822-2834.
When the airbag system deploys, a gas generator will fill the airbags, break open the padded covers, and inflate between the steering
wheel and the driver and between the instrument panel and the front
passenger. The airbags will deflate immediately after deployment so
that the front occupants can see through the windshield again
without interruption.
All of this takes place in the blink of an eye, so fast that many people
don 't even realize that the airbags have deployed . The airbags also
inflate with a great deal of force and nothing should be in their way
when they deploy . Front airbags in combination with properly worn
safety belts slow down and limit the occupant's forward movement.
Together they help to prevent the driver and front seat passenger
from hitting parts of the inside the vehicle while reducing the forces
acting on the occupant during the crash. In this way they help to
reduce the risk of injury to the head and upper body in the crash.
Airbags do not protect the arms or the lower parts of the body.
Both front airbags will not inflate in all frontal collisions . The trig­
gering of the airbag system depends on the vehicle deceleration rate
caused by the collision and registered by the electronic control unit.
If this rate is below the reference value programmed into the control
unit , the airbags will not be triggered, even though the car may be
badly damaged as a result of the collision. Vehicle damage , repair .._

n at ure (h ard or s oft) of th e obje ct whi ch the c ar hits , the ang le of
impact, vehicle speed, etc. The front airbags will also not inflate in
s ide o r rear coll isions , or in roll-ove rs.
Always remember: Airbags w ill deploy only once, an d on ly in certa in
kinds of co llisio ns. Your safety be lts are a lways there to offer protec­
t ion in those s ituatio ns in which airbags ar e no t sup pose d to d eploy,
or w hen they have alrea dy de ploye d; for examp le, when your ve hicl e
st rikes or is st ruc k by ano ther afte r the first collis io n.
T hi s is just one of the reasons w hy an airbag is a s upplementa ry
restra in t a nd is no t a su bst itute for a safe ty bel t. The air bag sy stem
works most effectively when used with the safety be lts. Therefore,
always p rope rly wear y ou r safety belts => page 189 .
& WARNING
Sitting too close to the steering wheel or instrument panel will
decrease the effectiveness of the airbags and will increase the risk
of personal injury in a collision.
• Never sit closer than 10 inches (25 cm) to the steering wheel or
instrument panel.
• If you cannot sit more than 10 inches (25 cm) from the
steering wheel, investigate whether adaptive equipment may be
available to help you reach the pedals and increase your seating
distance from the steering wheel.
• If you are unrestrained, leaning forward, sitting sideways or
out of position in any way , your risk of injury is much higher.
• You will also receive serious injuries and could even be killed if
you are up against the airbag or too close to it when it inflates - even with an Advanced Airbag.
& WARNING (co ntinued )
• To reduce the risk of injury when an airbag inflates, always
wear safety belts properly=>
page 193, "Safety belts ".
• Always make certain that children age 12 or younger always
ride in the rear seat. If children are not properly restrained, they
may be severely injured or killed when an airbag infl ates .
• Never let children ride unrestrained or improperly restrained in
the vehicle. Adjust the front seats properly.
• Never ride with the backrest reclined.
• Always sit as far as possible from the steering wheel or the
instrument panel =>
page 178.
• Always sit upright with your back against the backrest of your
seat.
• Never place your feet on the instrument panel or on the seat.
Always keep both feet on the floor in front of the seat to help
prevent seriou s injuries to the legs and hips if the airbag inflates.
• 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 braking or in a sudden maneuver. Objects near the
airbags can become projectiles and cause injury when an airbag inflates .
& WARNING
Airbags that have deployed in a crash must be replaced .
• Use only original equipment airbags approved by Audi and
installed by a trained technician who has the neces sary tools and
diagnostic equipment to properly replace any airbag in your
vehicle and assure system effectiveness in a crash.
• Never permit salvaged or recycled a irbags to be installed in
your vehicle. •

Child restraints on the front seat - some
important things to know
- Be su re to re ad t he i mpo rt a nt i nfo rmation a nd head the
WA RNINGS fo r i mporta nt details about chil dre n and
Advanced Airbags ~
page 221.
Even t hough your ve hicle is eq uipped with an Advanced Airbag
System, ma ke ce rtain that a ll chi ld ren, especia lly those 12 years an d
younger, always r ide in the back seat prope rly rest rained fo r th eir age
and si ze. The airbag on the passenger side makes the front seat a
po tentially da ngerous place fo r a child to r ide. The fro nt seat is not
the safest place for a ch ild in a forward-facing child safety seat. It can
be a very dange rous place fo r an i nfan t or a child in a rearward-fac ing
seat.
Th e Advanced Ai rbag System in your vehicle has been cer tified to
comply with the Req uirements of Uni ted States Federa l Motor
Vehicle Safety Standard 208 as applicable at the time your veh icle
was ma nufact ured .
The Standard requires the front airbag on the passenger side to be tu rne d off ("s uppressed") if a c hild up to abou t one ye ar of age
restra ined in o ne of the rear -facing or forward -fac ing infant
restra ints listed in Fed era l Moto r Vehicle Safety Standard 208 with
whic h the Advanced Airbag System in yo ur vehicle was cert ified has
been installed on the front passenger seat. For a listing of the ch ild
restra in ts that were used to certify compliance with the US Saf ety
Standard =>

The PASSENGER AIR BAG OFF ligh t in th e in st rume nt p anel t ells you
when the front Advanced A irbag on the passenger side has been
tur ned off by the ele ct ronic con trol uni t.
Each time you t urn on the ignition, t he

T he
PASSENGER AIR BAG OFF light comes o n when t he control unit
de tects a total weight on t he front passenger seat that req uires the
front airbag to be t urned off .
If th e total weight o n the front passenger seat is more than th at of a
typical 1 year-o ld child but less than the weight of a small adult, the

light does not come on, the front airbag on the passenger side has
not been turned off by the electronic co ntrol unit and can deploy if
the control unit senses an impact t hat meets the conditions stored in
its memory.
For example, the airbag may deploy if:
• a small child that is heavier than a typical 1 year -old child is on the
front passenger seat (rega rd less of whether the chi ld is in one of the
child safety seats listed =>
page 223), or
• a child who has outgrown child restraints is on the front passenger
sea t.
If the fro nt passenger a irbag is tur ned off, the
PASSENGER AIR BAG

& 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 Advanced 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 circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer.
• Forward-facing child safety seats installed on the front
passenger's seat may interfere with the deployment of the airbag
and cause serious personal injury to the child.
& WARNING
If , in exceptional circumstances , you must install a forward-facing
child restraint on the front passenger's seat:
& WARNING (continued)
• 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 side airbag.
• Never put the forward-facing child restraint up against or very
near the instrument panel.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the
airbag as possible before installing the forward-facing child
restraint. The backrest must be adjusted to an upright position.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
& WARNING
To reduce the risk of serious injury, make sure that the PASSENGER AIR BAG OFF light will be displayed whenever a child
restraint is installed on the front passenger seat and the ignition
is switched on .
• If the PASSENGER AIR BAG OFF light does not stay on, perform
the checks described~
page 210, "Monitoring the Advanced
Airbag System ".
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on .
• Have the airbag system inspected by your authorized Audi
dealer immediately.
• Always carefully follow instructions from child restraint manu­
facturers when installing child restraints.
& WARNING
If , in exceptional circumstances , you must install a forward or
rearward-facing child restraint on the front passenger 's seat:

& WARNIN G (con tinued )
• Imprope r in stall ation of child re straints can redu ce their effec·
tiveness or even prevent them from providing any protection.
• An improperl y installed child re straint c an interfere with the
airbag a s it deploy s and seriously injure or even kill the child - even
with an Advanced Airbag Sy stem.
• Always carefully follow the manufacturer 's instruct ions
provided with the child safety seat or carrier.
• Ne ver place additional items on the seat that can increase the
total weight regi stered by the weight-sen sing mat and can cause
injury in a crash .•

& WARNING (conti nued)
• Even when they deploy, airbags provide only supplemental
protection.
• Airbag work most effectivel y when used with properly worn
safety belts .
• Therefore, always wear your safety belts and make sure that
everybody in your vehicle is properly restrained.
& WARNING
A person on the front passenger seat , especially infants and small
c hildren, will receive serious injuries and can even be killed by
being too close to the a irbag when it inflates .
• Although the Advanced Airbag System in your vehicle is
designed to turn off the front passenger airbag if an infant or a
small child i s on the front pa ssenger seat, nobody can absolutely
guarantee that deployment under these spec ial conditions is
impos sible in all conceivable situations that may happen during
the useful life of your vehicle .
• The Advanced Airbag System can deploy in a ccordance with the
" low risk" option under the U.S . Federal Standard if a child that is
heavier than the typical one-year old child is on the front
passenger seat and the other conditions for airbag deployment
are met.
• Accident statistics have shown that children are generally safer
in the rear seat area than in the front seating po sition .
• For their own safety , all children , especially 12 years and
younger, should alway s ride in the back properly re strained for
the ir age and size. •
Advanced front airbag system
Your vehicle is equipped with a front Advanced A irbag System in
comp li a nce wi th Unit ed State s F edera l Motor Vehicle Sa fety Sta ndar d
208 as applicable at t he time your veh icle was manufactured.
Th e front A dvanced A irbag System s upplements the safety belts to
prov ide addit ional p rotect ion fo r the driver's a nd front passenger's
hea ds and uppe r bodies in fronta l crashes . The airbags inflate only in
fronta l impa cts when the vehicle dece leration is high enoug h.
T he front Advanced Airbag System for the front seat occupants is not
a subs titu te for your s afe ty be lts. R athe r, it is part o f the ove rall occu­
pant restra int system in your ve hicle. Always remember t hat the
airbag sys tem ca n on ly hel p to protect you, if yo u are sitting upr igh t,
wearing your safety be lt and wear ing it prope rly . T his is why you and
your passengers must always be p roperly restra ined, not just beca use
t he law requires you to be .
The Advanced A irbag System in your veh icle has been cert ified to
meet the " low r isk " req uirem ents fo r 3 a nd 6 year-old childre n on the
passenger s ide and very small adu lts on the driver s ide. T he low r isk
dep loyme nt crite ria are in tende d to hel p r educe t he ris k of injury
throug h interaction with the front airbag that can occur, for example,
by being too close to the steering wheel and instr ume nt pane l whe n
t he airbag i nflates.
In addit ion, the system has been cert ified to comply with t he
"supp ression" requirements of the Safety Stand ard, to turn off the
front airbag for infants 12 mont hs old and younger who are
res trained on the fron t passenger sea t in child re strai nts th at ar e
listed in the Standard~

Advanced Airbag System components
Th e front passenger seat in your veh icle has a lot of very important
parts of t he A dvanced A irbag System in it. These parts incl ude t he
we ight-sens ing mat, sensors, wiring, brackets, and more. The func- tion of the system
in the front passenger seat is checked by the elec­
t ronic c ontro l unit w hen the ignitio n is o n. The contr ol unit mon itors
t he Advanced Airbag System and tu rns the airbag indicato r light o n
w hen a malfunction in t he system components is detected. The func­

& WARNING
(co ntinued )
• Never store item s under the front passenger seat . Parts of the
Advanced Airbag Sy stem under the passenger seat could be
damaged , preventing them and the airb ag system from working
properly .
• Never place seat covers or replacement upholstery that have
not been specifically approved by Audi on the front seats .
• Seat cover s can prevent the Advanced Airbag System from
recognizing child re straints or occupants on the front passenger
seat and prevent the side airbag in the seat backrest from
deploying properly .
• Never u se cushions, pillow s, blankets or similar items on the
front passenger seat. The additional padding will prevent the
weight-sensing mat in the seat from ac curately registering the
child restraint or person on the seat and prevent the Advanced
Ai rbag System from functioning properly .
• If you must use a child restraint on the front passenger seat
and the child restraint manufacturer's instructions require 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 ch ild restraint is
installed on the front passenger seat.
• If the PASSENGER AIR BAG OFF light does not come on and
stay on, immediately install child restraint in a rear seating posi­
tion and have the airbag system inspected by your authorized Audi dealer. •

Deployment of the Advanced A irbag System and the act ivat ion of the
safety belt pretensioners depend on the deceleration measured by
t he crash senso rs an d regis tered by the e lectroni c con trol u nit. The
amount of inflation of the front airbags can a lso be adapted to the
front seat pos it ion, depending on t he d istance be tween the respec ­
tive front seat and the steering wheel or instrument panel as reg is­
t ere d by sensors in the seats. Crash seve rity depends on speed and
deceleration as well as the mass and stiffness of the vehicle or object
involved in the crash .
On the passenger side, rega rd less of safety be lt use, the a irbag will
be t urned off if the we ight on the passenger seat is less tha n the
amount prog rammed in the e lec tronic contro l uni t. The fro nt airbag

Th e front airbags are designed to provide add itio na l protec tion for
the c hest and face of the driver and the front sea t passenge r when:
• safety belts are worn properly ,
• t he seats have been posit ioned so that the occupant is prope rly
seated as far as possible from the airbag,
• and the head restraints have been properly adjusted .
Because air bags inflate in the b link of a n eye w it h great force, things
you have on your lap o r have place d on the seat cou ld become
dangerous projectiles, and be pushed into you if the a irbag inf lates .
When a n airbag dep loys, fine dust is released. This is normal and is
not caused by a fire in the vehicle. This dust is made up mostly of a
powder used to l ubricate the ai rbags as they deploy.
It could irritate
skin .
I t is important to remember that while the supp lemental airbag
system is desig ned to reduce the li ke lihood of serious injur ies, other
injuries, for example swelling , b ruising and m inor abras ions, can also
happen when airbags infl ate. Airbags do not p rotect the arms or the ..,_
