the useful life of your vehicle .
- The Advanced Airbag System can deploy
in accordance with the "low risk" opt ion
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 othe r cond itions for airbag de­
ployme nt are met .
- Ac cident statist ics have shown that chi l­

Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with Un ited
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was manufactured .
The front Advanced Airbag System supple­ 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 dece le rat ion is high enough .
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety bel ts . Rather , it is part of the over­
a ll occupant restraint system i n your veh icle .
A lways remember tha t the airbag system ca n
on ly help to pro te ct yo u, if you are s itting up­
right , wearing yo ur safe ty belt and wearing it
properly. This is w hy you and yo ur passenge rs
m ust always be proper ly restrained, not just
because the law requires you to be.
The Advanced Airbag System i n your veh icle
has been certified to meet the " low ris k" re ­
qu irements 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 deployment crite- r
ia are intended to help reduce the r is k of i n­
jury through interaction with the front airbag that can occur, for example, by being too
close to the steering wheel and instrument
panel when the airbag inflates.
In addition, the system has been certified to
comply with the "s uppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months o ld and younger
who are restrained on t he front passenge r
seat in child restraints that are listed in the
Standa rd ¢
page 171, 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 about one year of age is re­ strained on the front passenger seat in one
of the rear -fac ing or fo rward-facing infant
restrai nts listed i n Federal Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your vehi cle was

Advanced Airbag System components
The front 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 unit mo nitors the Advanced Air­
bag Sys tem and turns the airbag indicator
light on when a ma lfunction in the system
components is detected . The function of the
ai rbag ind icator light is described in greater
detai l below. Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you must take care to
prevent it from be ing damaged . Damage to
the seat may prevent the Advanced A irbag for
the front passenger seat from doing its job in
a cra sh .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re ve hicle ac celera tion/de ce le ra ti on
to provide information to the Advanced Air­ bag System abo ut the severity of the crash . -
An elect ronic contro l unit, with integrated
crash sensors for front and side impacts .
The control un it "decides" whether to fi re
the front a irbags based on the informat ion
received from the crash sensors. The contro l
unit also "decides" whether the safety belt prete nsioners shou ld be act ivated .
- An Advanced A irbag w ith gas generator and
contro l valve for the driver ins ide the steer ­
ing wheel hub .
- An Advanced A irbag w ith gas generator and
contro l valve inside the instrument panel for
th e front passenger .
- A we ight-sensing mat under the upho lstery
padding of the fro nt passenge r seat cushion
that measures the total weight o n the seat.
The info rma tion reg iste red is sent continu­
ously to the elec troni c con trol un it to regu­
la te deployment o f the front Advanced Air ­

& WARNING
Damage to the front passenger seat can
prevent the front airbag from working
properly.
- 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 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. The amount of infla­
tion of the front airbags can also be adapted
to the front seat position, depending on the
distance between the respective front seat
and the steering wheel or instrument panel as registered by sensors in the seats. Crash se­
verity 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, regardless of safety
belt use, the airbag will be turned off if the
weight on the passenger seat is less than the

A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the risk of injury when the air­
bags inflate, the driver and passengers
must always sit in an upright posit ion,
must not lean against or place any part
of the ir body too close to the area where
the a irbags are located .
- Occupants who are unbelted, out of posi ­
t ion or too close to the airbag can be se­
riously injured by an airbag as it unfolds
with great force in the blin k of an eye
¢page 147.
A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System.
-The inflating airbag will hit the child seat
or infant carrier w ith great force and wi ll
smash the ch ild seat and child against
the backrest, center armrest, door or roof.
- Always install rear-facing child seats on
the rear seat.
- If you must install a rearward facing
child seat on the front passenger seat
because of exceptiona l circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rea r-facing chi ld seat in a
rear seating position and have the airbag
system inspected by your Aud i dealer.
A WARNING
Objects be tween you and the a irbag will
increase the risk of inj ury in a crash by in ­
terfering with the way the airbag unfolds
or by being pushed into you as the a irbag
inflates.
-

-Never hold things in you r hands o r on
your lap when the veh icle 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 air­
bags during braking or other sudden ma­
neuvers and become dangerous projec­
tiles that can cause ser ious personal in­
jury if the a irbags inflate.
- Never place or attach accessories o r oth ­
er objects (such as cup holders, te le­
phone b rac kets, large, heavy or bulky ob ­
jects) on the doors, ove r o r near the area
marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be ­
tween those areas and yo urself. These
objects could cause in ju ry in a crash, es­
pecially when the airbags inflate.
- Never recline the front passenger's seat
to transport objects. Items can a lso
move into the area of the s ide airbag or
the fron t airbag during braking or in a
sudden maneuver. Objects near the air­ bags can become projectiles and cause
in ju ry, partic ula rly when the seat is re­
clined.
A WARNING
T he fine dus t created when airbags deploy
can cause breathing prob lems fo r people
with a history of asthma or other breat h­
ing conditions.
- T o reduce the ri sk of breath ing problems,
those with asthma or other respiratory
conditions shou ld get fresh air right
away by getting o ut o f the veh icle or
open ing windows or doors .
- If you are in a collision in which airbags
deploy, wash your hands and face with mild soap and water before eating.
- Be careful not to get the dust into your
eyes, or into any c uts or scratches .
-If the resi due should get into your eyes,

A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag
from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the steering wheel horn pad or airbag cover or the instrument panel or modify them
many way .
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft , dry cloth or one
moistened 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 de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc .) must be performed by a
qualified technician who has the training
and special equipment necessary .
- For any work on the airbag system, we
strongly recommend that you see your authorized Audi dealer or qualified work­
shop.
- 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 replace­
ment upholstery over the front seat-
Airbag system 159
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately 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 replace­
ment parts designed and approved espe­
cially for your Audi model version . Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only.

Knee airbags
Description of knee airbags
The knee airbag system can provide supple ­
mental protection to properly restrained
front seat occupants.
Fi g. 1 52 Driver's a irbag
The drive r knee airbag is in the instr ume nt
panel underneath the steeri ng wheel
¢ fig . 152, th e ai rbag for the passenger is at
about the same height in the instrument pan ­
e l underneath the g love compartment.
The knee a irbag offers add itiona l pro tect io n
to the driver's and passenger 's knees and up­
per and lower thigh areas as a supp lements
the protect ion provided by the safety belts.
If the front airbags deploy, the knee airbags
a lso deploy in frontal collisions when the de­
p loyment thresho ld stored in the contro l unit
is met
r::!;> page 154, More important things to
know about front airbags.
In addition to t heir normal safety function,
safety be lts he lp keep the driver or front pas­
se nger in posit ion in a frontal coll is ion so that
the airbags ca n prov ide supplemental protec­
tion .
T he airbag system is not a s ubst itute for yo ur
safety be lt. Rather, it is part of the overall oc­
cupa nt restraint system in your veh icle. Al­
ways remember that the airbag system ca n
only help to pro tect you if you are wea ring
your safety belt and wear ing it prope rly. Thi s
i s w hy you sho uld always wea r yo ur safety
be lt, not just because the law requires yo u to
do so
¢ page 137, General notes .
Airbag system 161
The safety belt buckle fo r the driver a nd front
seat passe nger have switches that tell the air­
bag control module if th e safety belt is being
u sed or not . If the safety belt is being used,
the knee airbag w ill deploy at a s light ly higher
rate of deceleration t han if t he be lt is not be ­
i ng used. Therefore, in a pa rticular co llision, it
is possible that an airbag will not dep loy at a
seat ing pos ition w he re t he safety be lt is being
u sed b ut w ill infl ate a t the po sition where the
safety belt is no t being used.
Remember too, a irbags wi ll deploy o nly once
and on ly in certa in kin ds of ac ciden ts -yo ur
sa fe ty belts a re a lw ay s there t o offer p rotec ­
t ion in those accide nts in which airbags are
not supposed to dep loy o r when they have al ­
ready dep loyed, for example when your vehi­
cle strikes or is struck by another after the
first collision.
This is just one of the reasons why an airbag is
not a s ubstitute fo r th e safety be lt . T he airbag
system works most effect ively when used with
the safety be lts. Therefore, always wea r your
safety belts correct ly.
It is important to remember that while the
supplementa l knee airbag system is designed
to reduce the li kelihood of ser ious injuries ,
other injur ies, for example, swelling, bru is ing,
minor abras ions and frict ion bu rns can a lso
occur when an airbag in flates.
The knee airbag system basically consists
of:
- The electronic control module
- Two inflatable a irbags (a irbag an d gas gen-
erator), one for the d river and one fo r the
front passenge r
- The a irbag indicator lig ht in t he i nstrument
pane l
The knee airbag system will not deploy :
-when the ignit io n is switched off
- in frontal collisions when the de celera tion
meas ured by the contro l unit is too low
- in side co llisions
- in rear-end col lis ions
- in rollove rs

.&_ WARNING
-Safety belts and the airbag system can
only provide protection when occupants
are in the proper seating position
¢page 154 .
-If the airbag indicator light comes when
the vehicle is being used, have the sys­
tem inspected immediately by your au­
thorized Audi dealer.
How knee airbags work
The risk of injury to the leg area can be re­
duced by fully inflated knee airbags.
Fig. 153 Infla ted airbags pro tecting in a fron ta l coll i­
sio n
The knee airbag system has been designed so
that the airbags for the driver and front pas­
senger deploy in certain but not all frontal
collisions .
If the front ai rbags deploy, the knee ai rbags
also deploy in frontal collisions when the de­
ployment threshold stored in the control unit
is met .
When the system deploys, the ai rbags fill
with a propellant gas, and inflate between the lower part of the instrument panel and the
driver and the lower part of the instrument
panel and the front passenger~
page 154,
fig. 150.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the lower
extremities . 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 it is im­
portant for occupant safety that nothing
should be in their way when they deploy .
Fully inflated airbags in combination with
properly worn safety belts slow down and lim­
it the occupant's forward movement and help
to reduce the risk of injury .
Important safety instructions on the
knee airbag system
Airbags are only supplemental restraints . Al­
ways 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 .
.&_ WARNING
An inflating knee airbag can cause serious
injury. Wearing safety belts incorrectly and
improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you are seated too close
to any of the airbag locations. When ad­
justing their seat positions, it is impor­
tant that both the driver and the front passenger keep their upper bodies and
knees at the following minimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru­ ment panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru­
ment panel.
- The risk of personal injury increases if
you lean forward or to the side, or if the
seat is improperly positioned and you are
not wearing your safety belt . The risk in­
creases even more should the airbag de­
ploy .

-Always mak e sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter­
fering with the way the airbag deploys or by being pushed into you as the airbag
deploys.
- Never let anybody, especially children
or animals ride in the footwell in front
of the passenger seat.
If the airbag de­
ploys, this can result in serious or fatal
injuries .
- Never carry objects of any kind in the
footwell area in front of the driver's or
passenger's seat. Bulky objects (shop ­
ping bags, for example) can interfere
with or prevent proper deployment of
the airbag. Small objects can be
thrown through the vehicle if the air­
bag deploys and injure you or your pas­
sengers.
- Make sure there are no cracks, deep
scratches or other damage in the area of
the instrument panel where the knee air­
bags are located.
- If children are incorrectly seated, their
risk of injury increases in a collision

Side airbags
Description of side airbags
T he airbag system can provide supplemental
protection to properly restrained occupants .
Fig. 154 Side airbag location in t he d river 's seat
The side airbags are located in the sides of the
front seat backrests
Q fig. 154 and the rear

backrest facing the doors. They are identified
by the word "AIRBAG".
The side airbag system basically consists of:
- the electron ic control module and external
side impact sensors
- the two side airbags located in the sides of the front backrests
- two rear side airbags
- the airbag warning light in the instrument
cluster.
The airbag system is monitored electronically
to make certain that it is functioning properly
at all times. Each time you switch on the igni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics) .
T he side airbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the driver's, front and rear passenger's
upper torso on the side of the vehicle that is
struck in a s ide collision . The airbag deploys
only in side impacts and only when the vehicle
accelerat ion reg iste red by the control unit is
high enough.
If this rate is be low the refer­
ence value programmed into the control unit,
the side airbags will not be triggered, even
though the car may be badly damaged as a re­
sult of the co llision . It is not possib le to de­
fine an airbag triggering range that will cover
every possible angle of impact, since the cir­
cumstances will vary considerably between
one collis ion and another . Important factors
include, for example , the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed , etc.

safety instructions on the side airbag system .
Aside from their normal safety function, safe­
ty belts work to help keep the driver or front
passenger in position in the event of a side
collision so that the side airbags can provide
protection.
The airbag system is
not a substitute for your
safety belt. Rather, it is part of the overall oc­
cupant restraint system in your vehicle. A l-
ways remember that the side airbag system
can only help to protect you if you are wearing
your safety belt and wearing it properly. This

170 Child Safety
-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 in exceptiona l circumstances and
the
PASSENGER AIR BAG OFF light does
not come on and stay on, immed iately
install the rear-facing child safety seat in
a re ar seating posit ion and have the air­
bag system inspec ted immediately by
yo ur Audi dealer.
_& WARNING
If, in exceptional circumstances, you must
install a forward -facing child restraint on
the front passenger's seat:
- Always make su re the forward-fac ing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Always follow the man ufacturer's in­
struct ions provided with the child safety
seat or carrier.
- 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 installing
the ch ild restraint. The backrest must be
adjusted to an upr ight position .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
Advanced front airbag system and
children
Your vehicle is equipped with a front "Ad ­
vanced A irbag System" in compliance wit h
United States Federal Motor Vehicle Safety
Standard (FMVSS) 208 as app licab le at the
time your veh icle was manufactured.
The Advanced Airbag system in your vehicle
has been certified to meet the " low-risk" re­
qu irements for 3- and 6-year old ch ildren on
the passenger s ide and small adults on the
driver side . The low risk deployment criter ia are intended
to red uce the risk of in jury
thro ugh interaction with the airbag that can
occur, for examp le, by being too close to the
steering wheel and instrument panel when
the a irbag inflates. In addition, the system
has been certified to comply with the "sup ­
pression" requirements of the Safety Stand­
ard, to turn off the front a irbag for infants up
to 12 months who are restrained on the front
passenge r seat in child restra ints that are list­
ed in the Standard .
Even though your veh icle is equipped with an
Advanced Airbag system, a ll children, espe­
cially those 12 years and younger, should al­
ways ride in the back seat properly res trained
for their age and size . The airbag on the pas­
senger side makes the front seat a potentially
dangerous place for a ch ild to ride . The front
seat is not the safest p lace for a child in a for­
ward-fac ing ch ild safety seat. It can be a very
dangerous place for an infant or a larger child
in a rearward-fac ing seat .
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in you r vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us ­
ing the weight-sens ing mat in the seat cush­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tens ion on the safety belt .
The weight-sensing mat measures total
weight of the child and the child safety seat and a ch ild blanket on the front passenger
seat. The we ight on the front passenger seat
is related to the design of the ch ild restraint
and its "footp rint", the s ize and shape of the
bottom of the child res traint as it sit s on the
seat. The weight of a ch ild restra int and its
"footprint" vary for different kinds of child re­
straints and for the different mode ls of the
same kind of chi ld restraint offered by ch ild
restraint manufacturers.
T he weight ranges fo r the individual types,
makes and models of child restraints that the .,._
