Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occu
pants .
Fig. 131 Loca tion of driver airbag: in steering wheel

st rument panel
Your veh icle is equipped with an "Advanced Air
bag System" in compliance with United States
Federa l Motor Vehicle Safety Standard
(FMVSS) 208, as well as Canada Motor Vehicle
Safety Standard (CMVSS) 208 as app licab le at
the time your vehicle was manufactured . The
safety belts for the seats have "pretensioners"
that help 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 belts also have load limiters to help reduce the forces applied to the body in a
crash.
The airbag fo r the driver is in the steering whee l
hub ¢
fig. 131 and the airbag for the front pas
senger is in the instrument panel¢
fig. 132. The
general location of the airbags is marked "AIR
BAG".
Airb ag sys tem
There is a lot you need to know about the airbags
in your vehicle . We urge you to read the detai led
information about airbags, safety belts and ch ild
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 your passengers, especially infants and small children .
_&. WARNING
Never rely on a irbags alone fo r protect ion.
- Even when they deploy, airbags provide only supplemental protection.
-Airbag work most effectively when used with proper ly worn safety be lts .
- Therefore, always wear your safety belts and make sure that everybody in your vehicle is
properly restrained.
_&. WARNING
--A pe rson on the front passenger seat, espe
cially infants and small ch ild ren, w ill receive
se rious inj ur ies and can even be k illed by be
i ng too close to the airbag when it inf lates.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the front passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un
der these special conditions is impossib le in
all conceivable situations that may happen
during the useful life of your vehicle .
- The Advanced Airbag System can dep loy in
accordance with the "low risk" opt ion under
the U.S. Federal Standard if a ch ild that is
heavier than the typ ical one-year old ch ild 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 sea t area than
in the front sea ting pos ition.
- For their own safety, all c hildren, especially
12 yea rs and younger, should always ride in
the back properly restrained for their age and size .

Airbag syste m
Advanced front airbag system
Your vehicle is equippe d with a fr ont Adva nce d
A irbag System in compl iance with Un ited States
F edera l Motor Vehicle Safety Standard 208, as
well as Canada Motor Vehicle Safety Standard
(CMVSS) 208 as applicable at th e tim e your vehi
cle was manufactured .
The front Advanced Airbag System supp lements
the safety belts to provide additional protection
for the driv er's and front passenger's heads and
upper bodies in frontal crashes . The airbags in
flate only in front al impacts when the veh icle de
celerat ion is high enough.
The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety be lts . Rather, it is part of the overall occupant re
stra int system in your vehicle. Always remember
that the airbag system can on ly help to protect
you, if you are sitt ing upr ight, wear ing your safe
ty belt and wear ing it prope rly . This is why you
and your passengers must always be prope rly re
s trai ned, not just because the law req uires yo u to
be .
The Advanced Airbag System in your veh icle has
been ce rtified to meet the " low r isk" requ ire
men ts for 3 and 6 yea r-old children on the pas
senger side and very sma ll adults on the driver
side . T he low risk dep loyment criteria are intend
ed to he lp reduce the risk of injury through i nter
action with the front a irbag that can occur, for
examp le, by being too close to the steering wheel
and ins trument pane l when the airbag inflates.
In addition, the system has been certified to
comply w ith the "suppression" requirements of
the Safety Standard, to turn
off the front a irbag
for i nfants 12 months old and younger who are
restrained on the front passenger seat in c hild re
stra ints that are listed in the Standa rd
¢ page 153, Child restraints and Advanced Air
bags.
"Suppression" requ ires the front a irbag on the
passenger side to be t urned
off if:
- a chi ld up to about one year of age is restra ined
on the fro nt passenger seat in one of the rear
facing or forward -facing infant restraints listed
134
in Federal Motor Veh icle Safety Standard 208
with which the Advanced Airbag System in your
veh icle was certified . For a list ing of the child
restraints that were used to cert ify your vehi
cle's compliance with the US Safety Standard
¢ page 153,
-weight less than a threshold leve l stored in the
control un it is detected on the front passenger
seat .
When a person is detected on the front passen ger seat , weighing more than the total weight of
a chi ld that is about 1 year old restrained in one
of the rear -facing or forward -fac ing infant re
straints (listed in Federal Motor Vehicle Safety
Standard 208 w ith w hich the Adva nced Ai rbag
System i n your veh icle was certified), the front
a irbag on the passenge r side may or may not de
ploy .
The
PASSENGER AIR BAG OFF lig ht comes o n
whe n the elect roni c control unit detects a tota l
weight on the front passe nger seat th at req uires
the front airbag to be turned

GER AIR BAG OFF
light does not come on, the
front airbag on the passenger side has not been
turned
off by the control unit and can dep loy i f
the control unit senses an impact that meets the
cond it ions stored in its memory .
If the total weight on the front passenger seat is
more than that of a typ ica l 1 year-old, but less
than the weight of a small adult, the front airbag
o n the passenger s ide may deploy (the
PASSEN

light does not come on) .
For example , the ai rb ag ma y deploy if :
- a small ch ild that is heav ier than a typica l 1
year-old child is on the front passenger seat (regard less of whether the child is in one of the
child safety seats listed¢
page 153),
-a child who has outgrown c hil d rest raints is on
the front passenger seat.

_&. WARNING
Damage to the front passenge r seat can pre
vent the front airbag from work ing properly .
- Improper repair or disassembly of the front
passenger and driver seat will prevent the
Advanced Airbag System from f unctioning
proper ly.
- Repairs to the front passenger seat mus t be
performed by qualified and proper ly trained
wo rkshop personne l.
- Never remove the front passenger or driver
seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
- Never d isassemble or remove pa rts from the
seat o r disconnect wi res from it.
- Never carry sharp objects in your pocke ts or
place them on the seat. If the weight-sens
ing mat in the passenger seat is p unctured
it cannot work proper ly.
- Never carry things on your lap or carry ob jects on the passenger seat. Such items can increase the weight reg istered by the
weight-sensing mat and send the wrong in
formation to the airbag control unit.
- Never store items under the front passenger
seat . Parts of the Advanced Airbag System
under the passenger seat could be dam
aged, preventing them and the airbag sys
tem from working properly .
- Never p lace seat covers or replacement up
holstery that have not been specifically ap
proved by Audi on the front seats.
- Seat covers can prevent the Advanced A ir

restraints or occupants on the front passen
ger seat and prevent the side airbag in the
seat backrest from deploying properly.
- 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 accu
rately registering the child restraint or per
son on the seat and prevent the Advanced
Airbag System from functioning properly .
- If you must use a child restraint on the front passenger seat and the child restraint man
ufacturer'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
child restraint is installed on the front pas
senger seat.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in
stall child restraint in a rear seating 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 offered by the
front three-point safety belts with pretensioners
and load limiters and the adjustable head re
straints to help reduce the risk of inju ry in a wide
range of accident and crash situations. Be sure to
read the important information about safety and
heed the WARNINGS in this chapter.
Deployment of the Advanced Airbag System and
the act ivation of the safety be lt pretensioners de
pend on the deceleration measured by the crash
sensors and regis tered by the electronic control
unit . Crash severity depends on speed and decel
eration as well as the mass and stiffness of the
vehicle or object involved in the crash .
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 pro grammed in the elect ronic control unit. The front
Airbag system
airbag on the passenger side will also be turned
off if one of the child safety 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
q page 130, Child restraints on the front seat -
some important things to know .
_&. WARNING
To reduce the risk of injury when an airbag in
flates, always wear safety belts properly.
- If you are unrestrained, leaning forward, sit
ting 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

Safety belts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfold properly and provide sup
plemental protection in a frontal collision .
The front airbags are designed to provide addi
tional protection for the chest and face of the
driver and the front seat passenger when:
- safety belts are worn properly,
- the seats have been positioned so that the oc-
cupant is properly seated as far as possible
from the airbag, ..,.

-and the head restraints have been properly ad -
justed .
Because airbags i nflate i n the blink of an eye w ith
g reat for ce, th ings you have on your lap or have
p laced on the seat cou ld become dangerous pro
jectiles, and be pushed into you if the airbag in
flates .
When an a irbag deploys, fine dus t is re leased.
This is normal 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 irr itate sk in.
It is important to remember that whi le the sup
p lemental airbag system is designed to reduce
the likelihood of serious injur ies, other in juries,
for example swelling, bruising and m inor abra
sions, can also happen when airbags inflate. Air bags do not protect the arms or the lower parts
of the body . Front airbags only supplement the
three po int safety belts in some fronta l co llisions
i n which the veh icle decelerat ion is high enough
to deploy the airbags.
Fr ont airbags w ill not deploy:
- if the ignit ion is switched off when a crash oc -
curs ,
- in s ide collisions,
- in rear-end collisions,
- in rollovers,
- when the crash decelerat ion measured by the
airbag system is less than the minimum thresh
o ld needed for airbag deployment as registered
by the electronic control unit.
The front pass eng er airbag will also not
depl oy :
- when the front passenger seat is not occupied,
- when the weight on the front passenger seat as
sensed by the Advanced A irbag System indi
cates that the front airbag on the passenger
s ide has to be turned off by the electronic con
trol unit (the
PAS SENGER AIR B AG OFF light
comes on and stays on) .
A WARNING
Sitting in the wrong pos ition can increase the
r is k of se rious i njury in c rashes.
138
- To reduce the risk o f injury when the airbags
inflate, the driver and passengers must al
ways sit in an upright position, must not
lean aga inst or place any part of their body
too close to the area where the airbags are
located.
- Occupants who are unbelted, out of posit ion
or too close to the airbag can be serious ly
in ju red by an airbag as it unfolds wit h great
force in the blink of an eye
c:> page 130.
A WARNING
A child in a rearward-fa cing child safety seat
installed on the front p assenger sea t 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 chi ld safety
seat o r infant ca rrier with great force and
w ill smash the child safety seat and child
aga inst the backrest, center a rmrest, door
or roof.
- Always install rear-fac ing ch ild safety seats
on the rear seat.
- If you must insta ll a rearwa rd facing child
safety seat on the front passenger seat be
cause of exceptional circumstances and the
PAS SENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rea r-facing child safety seat in a rear
seating position and have the ai rbag system
inspected by your au thori zed Au di d ealer.
A WARNING
Objects between you and the airbag will i n
crease the r is k of injury in a crash by interfer
ing with the way the airbag unfolds or by be
ing p ushed into you as the airbag inflates .
- Never hold things in yo ur hands o r 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 airbags dur
ing braking or other sudden maneuver and
become dangerous projectiles that can
cause serious persona l injury if the airbags

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not functioning prop erly cannot provide supplemental protection
in a frontal crash .
- If the airbag indicator light
9 page 19
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup
posed to, or will not inflate when it should.
A WARNING
If the front airbag inflates, a child without a
child restraint, in a rearward-facing child safe
ty seat or in a forward-facing child restraint
that has not been properly installed will be
seriously injured and can be killed.
Airbag system
-Even though your vehicle is equipped with
an Advanced Airbag System, make certain
that all children, especially 12 years and
younger, always ride on the back seat prop erly restrained for their age and size .
- Always install forward or rear-facing child
safety seats on the rear seat -even with an
Advanced Airbag System .
- If you must install a rearward-facing child
safety seat on the front passenger seat be
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
appear and stay on, immediately install the
rear-facing child safety seat in a rear seating
position and have the airbag system in
spected by your authorized Audi dealer.
-A tight tether or other strap on a rearward
facing child restraint attached to the front passenger seat can put too much pressure
on the weight-sensing mat in the seat and
register more weight than is actually on the
seat . The heavier weight registered can
make the system work as though an adult
were on the seat and deploy the Advanced
Airbag when it must be suppressed causing
serious or even fatal injury to the child.
- If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger seat, always move the
seat into its rearmost position in the seat's
fore and aft adjustment range, as far away
from the airbag as possible. 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.
A WARNING
-- If the PASSENGER AIR BAG OFF light does
not go out when an adult is sitting on the
front passenger seat after taking the steps
described above, make sure the adult is
properly seated and restrained at one of the rear seating positions.
- Have the airbag system inspected by your

Repair , care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing , remov
ing, servicing or repairing a part in an area of the
vehicle can damage a part of an airbag system and prevent that system from working properly in a collision.
There are some important things you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
Improper care, servicing and repair proce
dures can increase the risk of personal injury
and death by preventing an airbag from de
ploying when needed or deploying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the steer
ing wheel horn pad or airbag cover or the in
strument panel or modify them in any way .
- Never attach any objects such as cupholders
or telephone mountings to the surfaces cov
ering the airbag units.
- For cleaning the horn pad or instrument panel, use only a soft, dry cloth or one mois
tened with plain water. Solvents or cleaners could damage the airbag cover or change
the stiffness or strength of the material so
that the airbag cannot deploy and protect properly.
- Never repair, adjust , or change any parts of
the airbag system.
- All work on the steering wheel, instrument
panel, front seats or electrical system (in
cluding the installation of audio equipment,
cellular telephones and CB radios, etc.)
must be performed by a qualified technician
142
who has the training and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your au
thorized Audi dealer or qualified workshop .
- Never modify the front bumper or parts of
the vehicle body.
- Always make sure that the side airbag can
inflate without interference:
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi .
- Never use additional seat cushions that
cover the areas where the side airbags in
flate.
- Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi
ately by an authorized Audi dealer .
- The airbag system can be activated only
once . After an airbag has inflated, it must
be replaced by an authorized Audi dealer or
qualified technician who has the technical
information, training and special equipment
necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed, it
must be replaced with new replacement
parts designed and approved especially for
your Audi model version. Replacement of complete airbag systems or airbag compo
nents must be performed by qualified work
shops only. Make sure that any airbag serv
ice action is entered in your Audi Warranty
& Maintenance booklet under AIRBAG RE
PLACEMENT RECORD.
- In accidents when an airbag is deployed, the
vehicle battery separates the alternator and
the starter from the vehicle electrical sys
tem for safety reasons with a pyrotechnic
circuit interrupter.
- Work on the pyrotechnic circuit interrupt
er must only be performed by a qualified
dealer - risk of an accident!
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed.
