The PASSENGER AIR BAG O FF light is located in
the c enter of the instrument panel¢
fig. 149 .
The PASS ENGER AIR BAG OFF light will come on
and stay on to tell you when the front Advanced
Airbag on the passenger side has been turned off
by the el ectronic control unit . Each time you turn
on the ignition, the
P ASSENGER AIR BAG OFF
light will flash for a few seconds and:
- will stay on if the front passenger seat is not
occupied,
- will stay on if the re is a sma ll child or child re­
straint on the front passenger seat,
- wi ll go out if the front passenge r seat is occu ­
pied by an adult as registered by the weight­
sensing mat .
The

- a rearward-facing child restrai nt has been in­
stalled on the front passenger seat , or
- a forward -facing child restra int has been instal ­
led on the front passenger seat, or
- the weight reg istered on the front passenger
seat is equal to or less than the comb ined
weight of a typical 1 yea r-o ld restrained in one
of the rear-facing or forward-fac ing infant re­
strain ts listed in Federal Motor Vehicle Safety
Standard 208 w ith which the Advanced A irbag
System in your vehicle was certified.

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
c> page 17
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, in a rearward-facing child safe­
ty seat or in a forward-facing child restraint
that has not been properly installed will be
ser iously injured and can be killed .
142
-Even though your vehicle is equipped with
an Advanced A irbag System, make certain
that all 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
safety seats on the rear seat -even with an
Advanced A irbag 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 l ight does not
appear and s tay on, immedi ately ins tall the
rear-facing child safety seat in a re ar seat ing
position and have the a irbag system in ­
spected by your a uthorized 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
author ized Audi dealer befo re t ransporting
anyone on the front passenger seat.

Airbag system
@ For the sake of the environment
Undeployed 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 safe­
ty belts with pretens ioners are scrapped, all
applicable laws and regulat ions must be ob­
served. 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
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, changing 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.
144
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 control module and prevent
the Advanced A irbag System from working
properly.
- Always make sure that nothing can inte rfe re
w ith the safety belt buckles and that they
are not obstructed.
Knee airbags
Description of knee airbags
Applies to: vehicles with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig. 150 Driver's knee a irbag
The driver knee airbag is in the instrument panel
underneath the steering whee l~
fig. 150, the
knee airbag for the passenger is at about the
same height in the instrument panel underneath
the g love compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and uppe r and
l ower thigh areas and supp lements the protec­
tion provided by the safety belts .
If the front airbags deploy, the knee airbags also
deploy in frontal collis ion s when the deployment
th reshold stored in the control unit is met
~ page 138, More important things to know
about front airbags.
In addition to their normal safety funct ion, safe-
ty belts help keep the driver or front passenger in
IJJ>

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 122, 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 m inor
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:

How knee airbags work
Applies to: vehicles with knee airbags
The risk of injury to the leg area can be reduced
by fully deployed knee airbags.
F ig . 15 1 Inflated ai rbags protecting in a fronta l co llision
T he knee air bag system has been designed so

ger dep loy in certain but not all fronta l co llisions.
If t he front airbags deploy, the knee a irbags also
deploy in frontal coll is ions when t he deploy ment

Airbag syste m
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 a irbags also inflate
with a great deal of force and it is important for
occupant safety that nothing should be in their
way when they deploy .
Fully inflated airbags in comb ination with proper­
ly worn safety belts slow down and limit the oc­
cupant 's forward movement and help to reduce
the risk of inju ry .
Important safety instructions on the knee
airbag system
App lies to : ve hicles w ith knee a irbags
Airbags are 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 .
,&. WARNING
An inflating knee airbag can cause ser ious in ­
jury. Wea ring safety bel ts incorrectly and im­
proper seating positions increase the r isk 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 locat ions. When adjusting their
seat positions, it is important that both the driver and the front passenger keep their
upper bod ies and knees at the following
min imum safe distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instrument panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru­ ment panel.
- The risk of persona l injury increases if you
lean forward or to the s ide, or if the seat is
improperly positioned and you are not wear­
ing your safety belt. The risk increases even
more should the airbag deploy .
146
-Always make sure that the knee a irbag can
inflate w ithout interference. Objects be­
tween you and the airbag can increase the
r isk of injury in an accident by interfering
w ith the way the airbag deploys or by being
pushed into you as the a irbag deploys .
- Never let anybody, especially children or anima ls ride in the footwell in front of the
passenger seat. If the airbag deploys, this
can result in serious or fatal injuries .
- Never carry objects of any kind in the foot­
well area in front of the driver's or pas­
senger's seat. Bulky objects (shopp ing
bags, for example) can interfere with or
prevent proper deployment of the a irbag.
Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passengers.
- Make sure there are no crac ks, deep scratch­
es o r othe r damage in the area of the inst ru­
ment panel where the knee airbags are lo­
cated.
- I f ch ildren are i ncorrectly se ated, their risk
of injury i ncreases in a col lision

The a irbag system is monitored electronically to
make certa in that it is func tioning properly at all
times. Each time you turn on the ignit ion, the air­
bag system indicator light will come on for a few
seconds (self diagnostics).
The s ide a irbag system supp lements the safety
be lts and can help to reduce the risk of injury to
the driver's and fron t passenger 's upper torso on
the side of the vehicle that is struck in a side col­ lision. The airbag d eploys on ly in side impacts
and only when the veh icle acceleration reg istered
by the contro l unit is high enough. If this rate is
below the reference value programmed into the
control un it, the s ide a irbags w ill not be tr ig­
gered, even though the car may be badly dam­
aged as a resu lt of the collision .
It is not possib le
to define an airbag trigge ring range that w ill cov­
e r every possible angle of impact, since the ci r­
cumstances wi ll vary considerably between one
collision and another. Important factors include,
for examp le, the nature (hard or soft) of the im ­
pacting objec t, the ang le of impact, vehicle
speed, etc. ¢
page 148, Impor tant safety in­
structions on the side airbag system .
Aside from their normal safety function, safety
be lts work to help keep the driver or front pas­
senger in posit ion in the event of a side collision
so that the s ide a irbags can provide protection .
T he airbag system is
not a substitute for your
safety belt. Rather, it is part of the overa ll occu­
pant restrain t system in your veh icle. Always re­
member that the s ide a irbag system can only
h elp to protect yo u if you a re wearing your safety
be lt and wea ring it properly. This is another rea­
son why you s hou ld always wear yo ur safety
be lts, not just bec ause the law req uires yo u to do

How supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained .
Fig . 1 53 Infla ted side airbags o n lef t s ide of vehicle
When the system is triggered, the airbag is filled
with propellant gas and breaks through a seam in
the seat surface area marked "AIRBAG". It ex ­
pands between the side trim panel and the pas­
senger . In order to help provide this additional
protection, the side airbag must inflate within a
fract ion of a second at very high speed and with
great fo rce. The supplemental side airbag could
inj ure yo u if your seating position is not proper or
upright or if items a re loca ted in the area where
the s upplemental side airbag expands. This ap­
plies especially to children¢
page 150, Child
safety .
Supplemental side a irbags inflate be­
tween the occupant and the door panel on the
side of the vehicle that is struck in certain side
collis ion ¢
fig. 153 .
Although they are not a soft p illow, they can
"cushion" the impact and in this way they can he lp to reduce the risk of injury to the upper part
of the body .
A fine dust may develop when the airbag deploys.
This is normal and does not mean there is a fire in the vehicle.

Important safety instructions on the side
airbag system
Airbags are only supplemental restraints . Always
properly wear safety bel ts and ride in a proper
seating position .
There is a lot that you and your passengers must
k now and act according ly to help the safety belts
and airbags do their job to prov ide supplemental
protect ion .
_& WARNING
An inflating side airbag can cause serious or
fatal injury. Improperly wearing safety be lts
and improper seating posit ions increase the
risk of serious persona l injury and death
whenever a vehicle is being used.
- In order to reduce the risk of injury when
the supplemental side airbag inflates:
- Always s it in an upr ight position and never
l ean agains t the area where the supple­
mental s ide airbag is located .
- Never let a child or anyo ne e lse rest their
head against t he side tr im panel in the
area where the s upplementa l side airbag
inflates .
- Always make s ure t hat safety bel ts are
worn correctly,
- Do no t let anyone s itting in the front seat
p ut their hand or any other par ts of their
body out of the window.
- Always make sure that the side a irbag can
inflate w ithout in terference.
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not bee n specifical ly approved by
A udi .
- Never use additional seat cushions that
cover the areas where the side airbags de­ ploy.
- 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 autho rized Aud i dealer .

Child safety
Child safety
Important information
Introduction
The rear seat is generally the safest place in a
collision .
The physical principles of what happens when
your vehicle is in a crash apply also to children
¢ page 123, What happens to occupants not
wearing safety belts? .
But unlike adults their
muscles and bones are not fu lly deve loped . In
many respects ch ildren are at greater risk of ser i­
ous injury in crashes than adults.
Because children's bodies are not fu lly devel­
oped, they requ ire restraint systems especially
des igned for their size, we ight, and body struc­
ture. Many countries and all states of the United
S tates and p rovinces of Canada have laws requir­
ing the use of approved child restraint systems
for infants and small children.
I n a frontal crash at a speed of 20-35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infant will be more than 20 times the
weight of the child. This means the weight of th e
child would suddenly be more than 260 pounds
(120 kg) . Under these conditions, only an appro ­
priate child restraint properly used can reduce
the risk of serious injury. Child restraints must be
used properly to be effective . Used improperly,
they can increase the risk of serious injury in an
accident.
Consult the child safety seat manufacturer's in ­
structions to be sure the seat is right for your
child's size¢
page 153, Important safety in­
structions for using child safety seats.
Please be
sure to read and heed all of the important infor­
mation and WARN INGS about ch ild safety, Ad­
vanced Airbags, and the installation of child re­
straints in this chapter.
There is a lot you need to know about the Ad­
vanced Airbags in you r vehicle and how they work
when infants and children in child restraints are
on the front passenger seat . Because of the large
amount of important information, we cannot re­
peat it all here. We urge you to read the detailed
150
information in this owner 's manual about airbags
and the Advanced Airbag System in your vehicle
and the very important information about trans­
porting children on the front passenger seat.
Please be sure to heed the WARNINGS - they are
extremely important for your safety and the safe ­
ty of your passengers, especially infants and small chi ldren .
&_ WARNING
-Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating position. Always restrain
any child age 12 and under in the rear.
- All vehicle occupants and especially children
m ust be restrained properly whenever riding
in a vehicle. An unrestrained or improperly
restrained child cou ld be injured by striking
the interior or by being ejected from the ve­ hicle during a sudden maneuver or impact.
An unrestrained or improperly restrained
child is also at greater r isk of injury or death
through contact w ith an inflating airbag .
- A suitable ch ild restraint properly installed
and used at one of the rear seating positions
provides the highest degree of protect ion
for infants and small children in most acci­
dent sit uat ions.
&_ WARNING
Children on the front seat of any car even with
Advanced Airbags can be ser iously injured or
even killed when an airbag inflates. A child in
a rearward-facing child safety seat installed
on the front passenger seat will be seriously
injured and can be killed if the front airbag in­
flates.
- The inflating airbag will hit the ch ild safety
seat or infant carrier with great force and
w ill smash the child safety seat and child
aga inst the backrest, center armrest or
door.
-Always install rearward-facing child safety
seats on the rear seat.
- If you must install a rearward facing child
safety seat on the front passenger seat in
