make certain that the PA SSENGER AIR BAG
OFF
light stays on continuous ly whenever the
ignit ion is on. If the
PASS ENGER AIR BAG
OFF
light does not appear and not stay on all
the time, stop as soon as it is safe to do so
and
- react ivate the system by turning the ignition
off and then turning it on again;
- remove and reinstall the child restraint.
Make sure that the child restraint is properly
installed and that the safety belt for the
front passenger seat has been correctly
routed around the child restraint as descr i­
bed in the child restraint manufacturer's in­
structions;
- make sure that the convertible locking fea­
ture on the safety belt for the front passen­
ger seat has been activated and that t he
safety belt has been pulled tight. The belt
must not be loose or have loops of slack so
that the sensor below the safety be lt latch
on the seat can do its job ¢
page 171.
-make su re that th ings that may increase the
weight of the chi ld and child safety seat are
not being transported on the front passen ­
ger seat;
- make sure that the safety belt tension sen­
sor is not b locked. Shake the safety belt
latch on the front passenger seat back and
forth;
- If a strap or tether is being used to tie the child safety seat to the front passenger
seat, make sure that it is not so tight that it
causes the we ight-sensing mat to measure
more we ight than is actua lly on the seat.
If the PASSEN GER AIR BAG OFF light st ill
doe s not come o n
and does not stay on con­
tinuously (when the ignition is switched on),
- take the chi ld restraint off the front passen -
ger seat and install it properly at one of the
rear seat pos itions . Have the a irbag system
inspected by your authorized Audi dealer
immediately .
- move the ch ild to a rear seat pos it io n and
make sure that the child is properly restrain­
ed in a child restraint that is appropriate for
i ts size and age. The

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An a irbag system that is not functioning
properly cannot provide supplemental pro­
tection in a frontal c rash.
- If the airbag ind icator light
¢ page 20
comes when the veh icle is being used,
have the system inspected immediately
by your authorized Audi dealer .
It is
-

154 Airbag system
-Never attach any objects such as cu­
pholders 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
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. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­ rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the restraint system including airbag modules
safety belts with pretensioners are scrap­
ped, all applicable laws and regulations
must be observed. Your authorized Audi
dealer is familiar with these requirements
and we recommend 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
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi, lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag sensors and sent to the electronic control
unit. Some suspension changes can, for

example, increase the force levels measured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if the changes had not been made. Other
kinds of changes may reduce the force levels
measured by the sensors and prevent the air ­
bag from deploying when it should.
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the
safety belt is being used but will inflate at the position where the safety belt is not being
used.
It is important that nothing interfere
with the safety belt buckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control unit .
& WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious personal injury in a crash.
- Never install suspens ion components
that do not have the same performance characteristics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING 1= -
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 con­
trol module and prevent the Advanced Air ­
bag System from working properly.
- Always make sure that nothing can inter-
fere with the safety belt buckles and that
they are not obstructed.
Airbag system 155
Knee airbags
Description of knee airbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants .
Fig. 154 Driver 's knee airbag
The dr iver knee airbag is in the instrument
panel underneath the steering wheel
¢ fig. 154, the knee airbag for the passenger
is at about the same height in the instrument
panel underneath the glove compartment.
The knee airbag offers additional protection
to the driver's and passenger's knees and up ­
per and lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags
also dep loy in frontal collisions when the de­
ployment threshold stored in the control unit
is met
¢ page 149, More impor tant things to
know abou t front airbags .
In addition to their normal safety function,
safety belts help keep the driver or front pas­
senger in position in a frontal collision so that
the airbags can provide supplemental pro tec­
tion.
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. Al­
ways remember that the airbag system can
only help to protect you if you are wearing
your safety be lt and wearing it properly. This
is why you should always wear your safety
belt, not just because the law requires you to
do so
¢ page 132, General notes. ..,_

156 Airbag system
The sa fety belt buck le for the driver and front
seat passenger have switches that te ll the ai r­
bag control module if the safety belt is being
used or not. If the safety belt is being used,
the knee airbag will deploy at a slightly higher
rate of deceleration than if the belt is not be­
i ng used. The refore, in a pa rticu la r collision, it
is possible that an airbag will not deploy at a
seating position where the safety belt is being used but will infla te at the position where the
safety bel t is not be ing used.
Remember too, airbags will deploy only once
and on ly in ce rtai n kinds of accidents -your
safety bel ts are always there to offer pro tec­
tion in those acc idents in which airbags a re
not supposed to deploy or when they have a l­
ready deployed, for example when your vehi­
cle strikes or is struck by another after the
f irst coll is ion.
This is just one of the reasons why an ai rbag is
n ot a substitute for the safety belt . The airbag
system works most effective ly when used with
the safety belts. Therefore, always wear your
safety belts correctly .
It is important to remember that whi le the
supp lemental knee a irbag system is designed
to reduce the likelihood of serious injur ies,
other injuries, for example, swell ing, bruising,
a nd minor abras ions and frict ion burns can al­
so occur when an a irbag inflates .
The knee airb ag sy stem basically con sists
of:
- The electronic control module
- Two inflatable airbags (airbag and gas gen-
erator), o ne for the driver and one for the
front passenger
- The airbag indicator light in the instrument
panel
The knee airbag sy stem will not deploy:
- when the ignition is turned off
- in frontal collis ions when the dece lerat ion
measured by the contro l unit is too low
- in s ide collisions
- in rear-end collisions
- in ro llovers -
in the event of a system malfunction (warn ­
ing/indicator light is on)
c::> page 20 .
A WARNING
--
-Safety belts and the airbag system can
only provide protection when occupants
are in the proper seating position
<=:> page
149.
-If the airbag ind icat or light r:::>page 20
comes w hen the veh icle is being used,
have the system inspected immediately
by your authori zed A udi dealer. It is pos­
sible that the airbag will in flate when it
is not supposed to, or will not infla te
when i t should.
How knee airbags work
App lies to vehicles: with knee airbags
The risk of injury to the l eg area can be re­
duced by fully deployed knee airbags.
Fi g. 1 55 Inf lated ai rbags protect ing in a frontal colli­
s io n
T he knee airbag system has been des igned so
that th e airbags for the driv er and front pas­
senger deploy in certa in but not all frontal
c ollisions.
If the front a irbags dep loy, the k nee a irbags
also dep loy in frontal coll isions w hen the de­
ployment th reshold stored in the contro l un it
is me t.
When the system deploys, t he ai rbags fill
with a p ropellant gas, and infla te between th e
lower pa rt of the inst rument panel and the
dr ive r and the lower part of t he instr ument
pane l and the fron t passenger <=:> page
149,
fig. 152.

Although they a re not a soft pillow, they can
cushion the impact and in this way they can he lp to reduce the r isk 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 w ith a great deal of force and it is im­
portant for occupant safety that noth ing
should be in the ir way when they deploy .
Fu lly inflated airbags in comb ination with
properly worn safety belts slow down and lim­
it the occupant's forward movement and help
to reduce the r isk of injury .
Important safety instructions on the
knee airbag system
Appl ies to vehicles : wit h kn ee a irbags
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
ai rbags to provide supp lemental protection .
A WARNING
An inflating knee airbag can cause ser ious
injury. Wear ing safe ty belts inco rrec tly and
improper seating posi tions increase the
risk o f serious personal injury and death
whenever a veh icle is being used .
- The knee airbag system cannot protect yo u properly if you are seated too close
to any o f the airbag locations. When ad­
just ing their seat positions, it is impor­
tant that both the drive r and the front
passenger keep their upper bodies and
knees at the follow ing min imum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instr u­
ment panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the inst ru­
ment panel.
A irbag system 157
-The risk of personal in jury increases if
you lean forward or to the s ide, or if the
seat is improperly positioned and you are
not wearing you r safety belt . The risk i n­
creases even more should the ai rbag de­
ploy .
- Always make sure that the knee a irbag
can inflate without inte rfe rence . Objects
between yo u and the airbag can inc rease
the risk of inj ury in an ac cident by inte r­
fering w ith the w ay the a irb ag deploys or
by being p ushed into you as the airbag
deploys.
- Never let anybody, especia lly children
o r anima ls ride in the footwell in front
of the passenge r seat . If the airbag de­
ploys, th is can result in serious o r fa tal
i njur ies.
- Never carry objects of any kind in the
footwell area in front of the dr iver's or
pas senger 's sea t. Bulky objects (sho p­
p ing bags, fo r example) can interfe re
with o r prevent proper deployment of
the ai rbag . Small objects can be
thrown thro ugh the veh icle if the air­
bag deploys and injure yo u 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 ch ildren are incorrectly seated, their
risk of injury increases in a collision

158 Airbag system
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants .
Fig. 156 Side a irbag locat io n in the dr iver 's seat
The s ide airbags are located in the sides of the
front sea t bac krests
~ fig. 156. They are iden­
tified by the word "AIRBAG" .
The sid e airbag system basicall y consis ts of :
-the electronic control module and external
side impact sensors
- the two side airbags located in the sides of
t h e front backrests
- the a irbag warn ing light in the instrument
cluster.
The airbag system is monitored electronica lly
to make certain that it is functioning properly at all times. Each time you turn on the igni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics) .
The s ide airbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the drive r's and front passenger's up­
pe r torso on the side of the vehicle that is
struck in a side col lision . The airbag deploys
on ly in side impacts and on ly when the veh icle
acceleration registered by the control unit is h igh eno ugh . If this rate is below the refer­
ence va lue programmed into the control un it,
the side airbags will not be triggered, even
though the car may be badly damaged as a re­ sult of the collision. It is not possible to de ­
f ine an a irbag tr igger ing range that will
cover
every
possible angle of impact, since the cir­
cumstances w ill
vary considerably between one collision and another.
Important factors
incl ude, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc .
Q page 159, Important
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 overa ll oc­
cupant restraint system in your vehicle. Al­
ways remember that the side airbag system
can only help to protect you if you are wea ring
your safety belt and wea ring it p roperly . This
is anothe r reason why you should always wear
yo ur safe ty be lts, no t ju st because the law re­
quires yo u to do so~
page 132, General
notes .
It is impo rtant to remembe r th at w hile the
s u pplementa l side airbag system is designed
to reduce the likelihood of ser ious inju ries,
othe r injuries, for example, swelling, br uising,
and minor abrasions ca n also be associated
with deployed side airbags. Remember too,
s ide airbags will deploy only once and only in
certain kinds of accidents -your safety belts
are always there to offer protection .
Vehicle damage, repair costs or
even the lack
of ve hicle damage are not necessarily an ind i­
cation of over-sensitive or failed airbag activa­
t io n. In some coll is ions, both front and side
airbags may inflate . Remembe r too, t hat air­
bags will deploy only once and on ly in ce rtain
ki nds of col lisions -yo ur safety belts a re a l­
ways there to offer pro tection in those acc i­
den ts in which airbags are not supposed to
deploy or when they have a lready deployed.
The side airbag system will not deploy:
- when t he ignit ion is tu rned off
- in side co llisions when the acceleration
measured by the sensor is too low
- in front -end collisions
- in rear-end collisions

- in rollovers.
I n some types of acc idents the front airbags
and side ai rbags may be t rigge red togethe r.
A WARNING
- Safety belts and t he a irbag sys tem will
only provide protection when occupan ts
are in the p roper seating posit ion
¢ page 159.
-If the airbag indicato r light c::> page 20
comes when the vehicle is be ing used,
have the system inspected immediately
by your authori zed Aud i dea ler. It is pos­
sible that the airbag will inflate when it
is not supposed to, or w ill not inflate
when it sho uld .
How supplemental side airbags work
.
Side airbags deploy ins tan tly and can help re­
duce the risk of upper torso injuries for occu ­
pants who are properly restrained .
Fig. 15 7 Infla ted s ide a irbag s on left s ide of ve hicle
When the system is trigge red , the airbag is
fi lled w ith p ropel lant gas and breaks thro ugh
a seam in the seat surface area marked "AIR­
BAG" . It expands between the side trim panel
and the passenger. In orde r to help provide
t his additional protection, the side a irbag
must inf late within a fraction of a second at
very high speed a nd with great force . The sup ­
p lemental side a irbag could injure you if your
seating position is not p roper or upr ight or if
items are located in the area where the sup ­
p lemental side a irbag expands . T his app lies
especia lly to children
c::> page 161, Child Safe­
ty.
Supplemental side airbags inflate between
the occupant and the door pane l on the side
A irba g sy stem 159
of the vehicle that is struck in certain side col ­
lision
c::> fig . 157 .
Although they are no t a soft pillow , they can
"cushion" the impa ct and in this way they can
help to reduce the risk of injury to the upper
part of the body .
A fine dust may develop when the airbag de­
ploys . T his is normal and does no t mean there
is a fire in the vehicle.
Important safety instructions on the
side airbag system
Airbags are only supplemental restraints . Al ­
ways properly wear safety belts and r ide in a
proper sea ting position.
T here is a lot that you and your passengers
must know and act accord ingly to help the
safety belts and airbags do the ir job to pro­
vide supplemental protect ion.
A WARNING ,-
An inflat ing s ide a irbag can cause se rious
or fata l injury . Improperly wearing safety
belts and imp roper seat ing pos itions in­
crease the risk of serious pe rsonal injury
and death whenever a vehicle is being
used.
- I n o rder to red uce the risk of i nju ry when
the s upplemental side airbag inflates:
- Always sit in an upright position and never lean against the area where the
suppleme nta l side airbag is located.
- Never let a child or anyone e lse rest
their head aga inst the s ide trim pane l
i n the area where the supplementa l
s ide a irbag inflates .
- Always make sure that safety belts are
worn correctly,
- Do not let anyone s itting in the front
seat put t he ir hand or any ot her parts
of their body out of the window .
- Always make su re t hat the side a irbag
can inflate without interfe rence .

Child Safety
Important things to know
Introduction
The rear seat is generally the safest place in a
collision .
The physical principles of what happens when
your veh icle is in a crash app ly also to chi ldren
q page 133, What happens to occupants not
wearing safety belts? .
But unlike adu lts thei r
muscles and bones are not fully developed. In
many respects children are at greater risk of
serio us inju ry in crashes than adults .
Because children's bod ies are not fu lly deve l­
oped, they require restraint systems especial ­
l y des igned for their size, weight, and body
structure. Many co untries and all states of th e
United States and p rovinces of Canada have
laws requ iring the u se of approved ch ild re­
straint systems for infants and small children .
In a frontal crash at a speed o f 20 -35 mph
(30-56 km/h) the forces acting on a 13-po und
(6 kg) infant w ill be more than 20 t imes the
weight of the child . Th is means the weight of
the child would suddenly be more than 260 pounds ( 120 kg). Under these conditions,
on ly an appropriate chi ld restrai nt properly
used can reduce the risk of ser ious injury.
Ch ild restr aints must be used p roperly to be
effective. Used improperly, they can inc rease
the risk of serious in jury i n an accident.
Consult the chil d safety seat manufacture r's
i nstr uctions to be s ure the seat is r igh t for
your chi ld's size
q page 164, Important safe ­
ty instructions for using child safety seats .
Please be sure to read and heed a ll of the im ­
portant informat ion and WARNINGS abo ut
child safety, Advanced Airbags, and the ins tal­
lation of child restraints in this chapter.
T here is a lot you need to know about the Ad ­
vanced A irbags in your vehicle and how they
work when infants and children in child re­
straints are on the front passenger seat . Be ­
cause of the large amount of important i nfor-
Child Sa fet y 161
mation, we cannot repeat it a ll here . We urge
you to read the detai led information in this
owner 's man ua l about airbags and the Ad ­
vanced Airbag System in your vehicle and the
very important information about transpor t­
ing ch ildren on the front passenger seat.
Please be sure to heed the WARNINGS -they
ar e extremely importa nt for your safety and
the safety of you r passenge rs, especially in­
f an ts and small chi ld ren.
A WARNING
- Accident statistics have shown that c hil­
dren are generally safer in the rear seat
area than in the front seating position.
Always restrain any child age 12 and un­
der in the rear.
- All vehicle occupants and especially chil­
dren must be restrained p roperly when­
ever riding i n a vehicle. An unrestrained
or improper ly restrained chi ld could be
in ju red by str iking the interior o r by be ­
ing ejected from the vehicle during a
sudden maneuve r or impact. A n un re­
s tra ine d or improperly restrained ch ild is
a lso at greate r risk of injury o r dea th
through contact with an inflating airbag .
- A suitable ch ild restrai nt properly inst al­
led and used a t one o f the rear seat ing
positions prov ides the highest degree of
protection for infants and small children
in most accident situations.
A WARNING
Children on the front seat of any car even
with Advanced Airbags can be ser iously in­
ju red or even killed when an a irbag i n­
flates. A child in a rearward -fac ing ch ild
safety seat installed on t he front passen­
ger seat w ill be ser iously injured and can
be killed if the front airbag infla tes.
- The infla ting airbag will h it the ch ild
s afe ty seat or i nfant carrie r wi th grea t
force and will sm ash the child safety se at
and child against the bac krest, cen ter
armrest o r door .
- Always install re arward-fac ing ch ild safe-
ty seats on the rea r seat .
