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-sens ing mat in the seat from accu­
rately reg istering the ch ild restraint or per­
son on the seat and prevent the Advanced
Airbag System from funct ioning prope rly.
- If you must use a child restraint on the front
passenge r seat and the child restraint man­
ufact urer's instructions require the use of a
towel, foam cushion or something else to properly position the chi ld restraint, make
certain that the
PASSENGER AIR BAG O FF
light comes on and stays on whenever the
child restraint is installed on the front pas­
senger seat.
- If the
PASSENGER AIR BAG O FF light does
not come on and stay on, immediately in­
stall child restrai nt in a rear seating position
and have the airbag system inspected by
you r Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
ai rbags supplement the protection offered by the
front three-point safety belts with pretensioners and load limiters and the adjustable head re ­
stra ints to help reduce the r isk of injury in a wide
range of accident and crash situations. Be sure to
read the important information about safety and heed the WARNINGS in th is chapter .
Deployment of the Advanced Airbag System and
the activation of the safety belt pretensioners de­ pend on the deceleration measured by the crash
sensors and registered by the electronic control
unit . Crash severity depends on speed and decel­
era tion as we ll as the mass and stiffness of the
vehicle or object invo lved in the crash.
On the passenger s ide, regardless of safety belt
use, the a irbag will be t urned off if the weight on
the passenge r seat is less than the amount p ro­
g rammed in the e lectron ic cont rol unit . T he front
154
airbag on the passenger side will also be turned
off if one of the chi ld seats that has been certi­
fied under Federal Motor Vehicle Safety Standard 208 has been recognized on the seat. The
PA S­
S EN GER AIR BA G OFF
light comes on and stays
on to tell you when the front Advanced A irbag on
the passenger side has been turned off

.&_ WARNING
To reduce the risk of injury when an airbag in­
f lates, always wear safety belts properly.
- I f you are unrestrained, leaning forward, sit­
ting sideways or ou t of position in any way,
your ris k of injury is much highe r.
- You will a lso receive ser ious injuries and
could even be killed if yo u are up against the
airbag or too close to i t when it inflates -
even with an Advanced Airbag

More important things to know about front
airbags
Fig. 165 Inflated front a irbags
-,... N 0 :i: ;;i;
Safety be lts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfo ld properly and prov ide sup­
plemental protection in a fronta l co llision.
The front airbags a re 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,
- t he seats have been positioned so that t he oc-
cupant is properly seated as far as possib le
from the airbag,
Ill-

-and the head restraints have been properly ad -
justed.
Because airbags inflate in the blink of a n eye w ith
great for ce, things you have on you r 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 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 lubricate the airbags as they deploy. It
could irr itate skin.
It is important to remember that while the sup­
p lemental airbag system is designed to reduce
the likelihood of ser ious injuries, other inj uries,
for example swell ing, bruising and minor abra­
sions, can also happen when airbags inflate. Air­
bags do not protect the arms or the lower parts
of the body . Front airbags supplement the three­
point safety belts only in some frontal collisions
i n which the veh icle decelerat ion is high enough
to deploy the airbags.
F ront airbags will 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 contro l unit .
Th e front passeng er airbag also will not
deplo y:
- when the front passenger seat is not occupied,
- when the weight on the front passenger seat as
sensed by the Advanced Airbag System indi­
cates that the front airbag on the passenger
s ide has to be turned off by the electronic con­
trol unit (the
P A SSENGER AIR B AG OFF light
comes on and stays on).
A WARNING
Sitting in the wrong pos ition can increase the
r isk of se rious injury in c rashes.
Airb ag sys tem
-To reduce the risk of injury when the ai rbags
inflate, the driver and passengers must al­
ways sit in an upright posit ion, 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 seriously in jur ed by an airbag as it unfolds with g reat
for ce in the blink of an eye
Q page 147.
A WARNING
A child in a rearward-facing child seat instal­
l ed on the front passenger seat will be se ri­
ously injured and can be killed if the front air ­
bag inflates - even with an Advanced Airbag
System .
- The inflating airbag will hit the child seat or infant carrier with great force and will
smash the child seat and child against the backrest, center armrest, door or roof.
- Always install rear-fac ing child seats on the
rear seat.
- If you must install a rea rward facing child
seat on the front passenger seat because of
except ional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immed iate ly install the rear­
faci ng chi ld seat in a rear seating posit ion
and have the airbag system inspected by
your Aud i dea le r.
A WARNING
-
-
Objects between yo u and the airbag will in­
crease the risk of injury in a crash by interfer­ i ng with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates .
- Never hold things in yo ur hands or on your
lap when the veh icle is in use .
- Never transport items on or in the a rea of
the front passenger seat . Obje cts could
move into the a rea of the front airbags dur­
ing b raking or other s udden maneuvers and
become dangerous projectiles that can
cause serious persona l injury if the airbags
inflate.
155

Airbag syste m
-Never place or attach accessories or other
objects (such as cup ho lders, te lephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked "AIRBAG" on the steering wheel, instru­
ment pane l, seat backrests or between
those areas and yourself. These objects
could cause injury in a crash, especially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objec ts. Items can also move into
the area of the side airbag or the front a ir­
bag dur ing braking or in a sudden maneu­
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined.
A WARNING
The fine dust created when airbags deploy can
cause breath ing problems for people w ith a
history of asthma or other breathing condi­
t ions.
- To reduce the risk of breathing problems,
those w ith asthma or other respiratory con­
ditions should get fresh air right away by
gett ing out of the vehicle o r opening w in­
dows o r doors.
- If you are in a collision in which airbags de­
ploy, wash your hands and fa ce with mild
soap and water befo re eat ing.
- Be careful not to get the dust into your eyes,
o r into any cu ts or sc ratches.
- If the resid ue should get into yo ur eyes,
flush them with water.
Monitoring the
Advanced Airbag System
~i (USA models)/!f (Canada models)
Airbag monitoring indicator light
Two separate indicators monitor the function of
the Advanced Airbag System: the airbag moni­
toring indicator light and the
PASSENGER AIR
BAG OFF
light.
The Advanced Airbag System (including the elec­
tron ic co ntrol unit, senso r ci rcui ts and system
w iri ng) is monitored con tinuously to make su re
156
that it is functioning properly whenever the igni­
tion is on. Each time you switch on the ignition,
the airbag mon itor ing indicator light
rl (U SA
models)/ E,I (Canada models) will come on for a
few seconds (se lf diagnostics) .
The system mu st be inspected wh en th e
indicat or light
II (USA models) /m (Canada
models ):
- does not come on when the ignition is sw itched
on,
- does not go out a few seconds after you have
sw itched on the ignit ion, or
- comes on while driving.
If an airbag system malfunction is detected, the
indicator light will first start flashing to catch the
driver's attention and then stay on continuously
to serve as a constant reminder to have the sys­
tem inspected immediately .
If a malfunction occurs that turns the front air­
bag on the passenger side off, the
PASSENGER
AIR BAG OFF
light will come on and stay on
whenever the ignition is on .
A WARNING
An airbag system that is not functioning prop­
e rly cannot provide supplemental protectio n
i n a fronta l crash.
- If the ai rbag ind icator light
Q page 18
comes when the veh icle is being used, have
t he system inspected immedia tely by your
author ized Audi dealer . It is possi ble that
the airbag will inflate when it is not sup ­
posed to, or will not inflate when it should .

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not funct ion ing prop­
er ly cannot p rovide supplemental p rotection
in a frontal crash .
- If the airbag indicato r light
r=>page 18
comes when the vehicle is be ing used, h ave
the system inspected immediate ly by yo ur
authorized Aud i dealer . It is possible that
the airbag will inflate when it is not s up­
posed to, or will not inflate when it should.
A WARNING
If the front airbag inflates, a child without a
child restraint, or in a rearward-facing child
safety seat, or in a forward-facing child re­
straint that has not been properly installed
w ill be seriously injured and can be killed .
158
-Even tho ugh your vehicle is equipped with
an Advanced A irbag System, make certain
that a ll children, espec ia lly 12 years and
younger, always ride on the back seat prop­
erly restrained for their age and s ize.
- Always install forward or rear-facing child
seats on the rear seat -even w ith an Ad­
vanced Airbag System .
- If you must install a rearward-facing child
seat o n the front passenge r seat because of
except ional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not appear and
s tay on, immediate ly ins tall the re ar-fa cing
child sea t in a rear seat ing pos ition and have
the airbag system inspected by your Audi
dea ler.
- A t ight tether or other s trap on a rearward­
facing chi ld 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 thoug h an adu lt
were on the seat and deploy the Advanced
Airbag when it must be suppressed causing
serious or even f atal injury to the child .
- If, in exceptional circumstances, you must
install a forward-fa cing child res traint on
the front p assenge r seat, always move the
seat into i ts rearmost posi tion in the sea t's
fore and aft ad justment range, as far away
from the ai rbag as possible . The back rest
must be adjusted to an upr ight 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
- If the PASSENGER AIR BAG OFF light does
not go out when an adult is sitting on the
front passenger seat afte r taking the steps
described above, make s ure the adult is
p roper ly sea ted and restra ined at one o f the
rear sea ting posit ions .
- Have the ai rbag system inspec ted by your
Aud i dea le r before tr anspor ting anyone on
the front passenge r seat .

(D Tips
If the weight-sensing mat in the front passen­
ger seat detects an empty seat, the front air­
bag on the passenger side will be turned off,
and the
P ASS ENGER AI R BA G OFF light will
stay on.
Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent p laces on your Aud i. Installing , remov­
ing, servic ing or repa iring a part in an area of the
vehicle can damage a part of an airbag system
and p revent that system from working properly
in a co llision.
There are some important things you have to
know to make su re that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
environm ent .
A WARNING
Improper care, serv icing and repa ir 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 a irbag cover or the in­
strument panel or mod ify them in any way .
- Never attach any objects such as cup holders or telephone mountings to the surfaces cov­
er ing the airbag units.
- For cleaning the horn pad or instrument
pane l, use on ly a soft, dry cloth or one mois­
tened with plain water. Solvents or cleaners cou ld damage the a irbag cover or change
the stiffness or strength of the material so
that the airbag cannot dep loy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All work on the steering wheel, instr ument
pane l, front seats or electrical system (in­
cluding the installation of audio equipment,
cellu lar telephones and CB radios, etc.)
must be performed by a qualified technician
Airb ag sys tem
who has the training and special equ ipment
necessary.
- For any wo rk on the airbag system, we
strong ly 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 a irbag can
inflate without interference:
- Never install seat covers or replacement
upholstery ove r the front seatbacks that
have not been specifica lly approved by
Audi .
- Never use addi tional seat c ushions that
cove r the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module must a lways be repaired immedi­
ate ly by an authorized Aud i dealer.
- The airbag system can be activated only
once . A fter an airbag has inflated, it must
be replaced by an authorized Audi dealer or
qualified technic ian who has the technical
information, t raining and spec ial equ ipment
necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed, it
must be replaced with new rep lacement
parts des igned and approved especially for
your Aud i model version. Replacement of
comp lete airbag systems or airbag compo­
nents must be performed by qualified work­
shops only. Ma ke sure that any airbag serv­
ice act ion is en tered in your Aud i Wa rranty
& Maintenance booklet under AIRBAG RE ­
PLACEMENT RECORD.
- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circ uit
interrupter.
- Wo rk on the pyrotechnic c ircuit inte rrupt­
er must on ly be performed by a qua lified
dealer -risk of an acc ident!
- If the vehicle or the circuit interr upter is
scrapped, all applicable safe ty p recau tions
mus t be followed.

@ For the sake of the en vironment
Undep loyed airbag modu les and pretension­
ers might be classified as Perchlorate Materi­
al -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­ rate . When the vehicle or parts of the re­
straint system including airbag modules and
safety belts w ith pretensioners are scrapped,
all applicable laws and regu lations must be
observed. Your authorized Audi dealer is fa­
m iliar with these requirements and we recom­
mend that you have your dealer perform this
service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
cha nge the way that the Advanced Airbag System
pe rforms in a crash. For example, using tire-r im
comb inat ions not approved by Audi, lower ing the
veh icle, chang ing the stiffness of the suspens ion,
including the spr ings, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspens ion changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
the sensors and preven t the airbag from deploy­
ing when it should .
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced A irbag performance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that do not have the same performance charac­
teristics as the components originally insta l­
led on your veh icle .
- Never use tire-rim comb inations that have
not been approved by Audi.
160
A WARNING
Items stored between the safety belt buckle
and the center console can cause the sensors in the buckle to send the wrong information
to the electronic contro l module and prevent
the Advanced A irbag System from wo rking
p roperly.
- Always make sure that noth ing can inte rfe re
w ith the safety belt buckles and that they
are not obst ructed.
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig. 167 Driver's kn ee ai rbag
The driver knee airbag is in the inst rument panel
u nderneath the s teer ing whee l
~ fig. 16 7, the
airbag fo r the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers add itiona l protection to
the d river's and passenge r's knees and uppe r and
l ower thigh areas and supp lements the protec ­
tion prov ided by the safety belts .
If the front airbags deploy, the knee airbags a lso
deploy in frontal coll is ions when the deployment
th reshold stored in the control unit is met
~ page 154, More important things to know
about front airbags.
In add ition to their normal safe ty f unct ion, safe-
ty belts help keep the driver or front passenger in ..,

position in a frontal collision so that the airbags
can provide supplemental protection.
The airbag system is not a s ubst itute for yo ur
safety belt. Rather, it is part of the overa ll occu­
pant restraint system in your vehicle. Always re­
member that the airbag system can only help to
protect you if you are wearing your safety belt
and wear ing it properly . This is why you should
always wear your safety belt, not just because
the law requires you to do soc::,
page 138, Gener ­
al information.
Remember too, airbags will deploy only once and
only in certain k inds of accidents -your safety
be lts
a re always there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have a lready dep loyed, for
examp le when yo ur vehicle str ikes or is str uck by
anothe r afte r the f irst collis ion.
This is just one of the reasons why an airbag is
not a substitute for the safety belt. The a irbag
sys tem wo rks most effec tively when used with
the safety belts. Therefore , al ways wear your
safety bel ts cor rect ly .
It is important to remember that while the sup­
p lemental knee a irbag sys tem is designed to re­
d uce the like lihood of serious injur ies, other inju­
ries, fo r example, swell ing, b ruising and minor
abrasions and fr iction burns can also occu r when
an airbag inflates.
The kne e airbag system basically consists of:
- The electronic contro l modu le
- Two inf latab le airbags (airbag and gas genera-
tor), one for the dr ive r and one fo r the front
passenge r
- T he airbag ind icator light in the instrument
pane l
The knee airbag system will not deploy:
-when the ignition is switched off
- in frontal collisions when the deceleration
measured by the control unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
Airb ag sys tem
-in the event of a system malfunction (warning/
indicator light is on)

.&_ WARNING
-
-Safety belts and the airbag system can only
provide protect ion when occupants are in
the proper seat ing pos ition
c::,page 154.
-If the airbag indicator light c::, page 18
comes w hen the veh icle is being used, have
the system inspected immediately by your
author ized Audi dealer. It is possible that
the airbag will inflate when it is not sup­
posed to, or w ill not inflate w hen it should.
How knee airbags work
The risk of injury to the leg area can be reduced
by fully inflated knee airbags .
Fig . 1 68 Inflated a irbags pro tecting in a frontal co llision
T he knee air bag system has been designed so
that the airbags for the driver and front passen­
ger dep loy in certain but not all fronta l co llisions.
If the front airbags deploy, the knee a irbags a lso
deploy in frontal coll is ions when the deployment
t h reshold stored in the control unit is met .
When the system deploys, the a irbags fi ll w ith a
prope llant gas, and infla te between the lower
part of the instrument panel and t he driver and
the lower part of the instrument panel and the
f ront passenger

Although they are not a soft pillow, they can
"cushion" the impact an d in this way they can
help to red uce the risk of inj ury to the lower ex­
tremities.

161

Airbag syste m
airbags have dep loyed . The airbags also inflate
with a great deal of force and it is important for
occupant safety that noth ing shou ld be in their
way when they deploy.
F u lly inflated airbags in combination with proper ­
ly worn safety belts slow down and limit the oc­
cupant's forward movement and he lp to reduce
the risk of injury.
Important safety instructions on the knee
airbag system
Airbags ore only supplemental restraints. Always
wear safety belts correctly and ride in a proper
seating position .
There is a lot that you and your passengers must
know and do to help the safety belts and airbags
to provide supplemental protection .
A WARNING
An inflating knee airbag can cause ser ious in­
jury. Wea ring safety belts incor rect ly and im­
proper seating pos it ions increase the r isk of
ser ious persona l injury and dea th whenever a
vehicle is being used.
- T he knee airbag system cannot protec t you
properly if you are seated too close to any o f
the airbag locatio ns. When adjusting their
seat positions, it is important that both the
dr iver and the front passenger keep their
upper bod ies and knees at the following
minimum safe distances:
- at least 10 inches (25 cm) between the
chest and the s teer ing whee l/instrumen t
panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the i nstru­
ment panel.
- The r isk of persona l injury inc reases if you
lean forward or to the s ide, or if the seat is
imp roperly positioned and yo u are not wear­
ing yo ur safety belt. The risk increases even
more should the a irbag deploy.
- Always make sure that the knee airbag can
inflate without interference. Objects be­
tween you and the airbag can increase the risk of injury in an accident by interfering
162
w it h the way the airbag deploys or by being
pushed into yo u as the a irbag deploys.
- Neve r let anybody, especia lly childre n or
anima ls ride in the footwell in front of the
passenger seat.
If the airbag de ploys, this
can result in serious or fa tal in juries.
- Never ca rry objects of any kind in the foot­
well a rea in front of the driver's or pas­
senger's seat . Bul ky objects (shopp ing
bags, for example) can interfere with or
prevent proper dep loyment of the airbag .
Small objects can be thrown through the
vehicle if the airbag deploys a nd injure you
or your passengers.
- Make sure there are no cracks, deep scratch­
es or other damage in the area of the instru­
ment panel where the knee airbags are lo­
cated .
- If ch ildren are i ncorrectly seated, their risk
of injury increases in a col lision
