- a passenger who is not sitting upright with
their back against a non-reclined backrest
with their feet on the vehicle floor in front
of the seat is on the front passenger seat.
I f the front passenger airbag deploys, the
Federal Standard requires the airbag to meet
the " low risk" deployment criteria to help re­
duce the risk of in jury through interaction
with the airbag . "Low risk" deployment occurs
in those cr ashes that take place at lower de­
celerations as defined in the electronic control un it

Always rem ember : Please be sure to read the
impor tant informa tion in the sections tha t
follow and be sure to heed all of the WARN ­
INGS .
A WARNING
To reduce the r isk of injury when an airbag
inf lates , a lways wear safety belts prope rly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of in jury is much higher.
- You w ill also receive serious inju ries and
cou ld even be killed if you are up against
the a irbag or too close to it whe n it in­
flates - even with an Advanced Airbag
Q page 108.
A WARNING
-
A child in a rearward-facing child safety
seat insta lled on the front passenger seat
w ill be seriously injured and can be k illed if
the front a irbag inflates - even with an Ad­
vanced Airbag System .
- Although the Advanced A irbag System in
your vehicle is designed to turn off the
front a irbag when a rearward -fac ing
child restraint has been installed on the
front passenger seat, nobody can abso­ l u te ly guarantee that deployment is im ­
poss ible in a ll conce ivable situations th at
may happen d uring the useful life of your
vehicle. -
The inflating airbag will h it the ch ild
safety seat or infant carrier with great
force and will smash the child safety seat and child aga inst the backrest, door, or
roof.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptiona l circumstan­
ces and t he

A WARNING
--=
If, in exceptiona l circumstances, you m ust
i nstall a forward -facing child restraint on
the front passenger's seat:
- Always make sure the forward- facing
seat has been designed and certified by
its manufacturer for use on a front seat
wit h a passenger front and s ide a irbag.
- Never p ut the fo rward-facing chi ld re ­
straint up against or very near the instru­
ment panel.
- Always move the passenger seat into its
rea rmost pos ition in the seat's fore and
aft ad justment range, as far away from
the airbag as possible, before install ing
the forward-fac ing ch ild restra int . The
backrest must be ad justed to an up right
position.

Advanced Airbag System components
The front passenge r seat in yo ur vehicle has a
lot of very important parts of the Advanced
Airbag System in it . These parts i nclude the
weight-sensing mat, sensors, wiring, brack­ ets, and more. The funct ion of the system in
the front passenger seat is checked by the electron ic control unit when the ignition is on .
The cont rol unit monito rs the Advanced A ir­
bag System and turns the airbag indicato r
li ght on w hen a malfun ct io n in t he system

components is detected . The function of the
airbag indicator light is described in greater
deta il below . Because the front passenger
seat contains important parts of the Ad­
vanced Airbag System, you must take care to
prevent it from being damaged. Damage to
the seat may prevent the Advanced A irbag for
the front passenger seat from doing its job in
a crash.
The f ront Ad vanc ed Airb ag S ystem
consists of the following:
- Crash sensors in the front of the veh icle that
measu re ve hicle acceleration/deceleration
to provide information to the Advanced Air­
bag System about the severity of the crash.
- An electronic control unit, with integrated
c rash sensors for front and side impacts.
T he contro l unit "decides" whether to fire
the front airbags based on the information
received from the crash sensors . The control
unit also "decides" whether the safety belt
pretensioners should be activated.
- An Advanced Airbag with gas generator for
the driver ins ide the steer ing wheel hub.
- An Advanced Airbag with gas generator in­
side the instr ument panel for the front pas­
senger.
- A weight-sensing mat under the upholstery
padding of the front passenger seat cushion
that measures the total weight on the seat.
The information registered is sent continu­
ously to the electron ic control unit to regu­
late dep loyment of the front Advanced Air­
bag on the passenger side.
- An a irbag monitoring system and indicator
li ght in the instrument cluster

you when the front Adv anced Airbag on the
passenge r side has been turned off.
- A senso r below the safety belt latch for the
front seat passenger to me asure the tension
on the safety belt . The tens ion on the safety
belt and the weight registered by the
weight-sensing mat help the control unit
"dec ide" whether the front airbag for the

not
¢ page 109, Child restraints on the
front seat -some important things to
know.
- A sensor in the safety belt latch for the driv­
er and for the front seat passenger that
senses whether that safety belt is latched or
not and transmits this information to the
electronic control unit .
.&, WARNING
Damage to the front passenger seat can
prevent the front airbag from wor king
properly.
- Improper repai r or d isassembly of the
front passenge r and dr iver seat will pre­
vent the Advanced Airbag System from
functioning properly.
- Repairs to the front passenge r seat must
be pe rformed by qualified and p roperly
trained workshop personne l.
- Never remove the front passenger o r
driver seat from the vehicle .
- Never remove the upholstery from the
front passenger seat.
- Neve r d isassemble o r remove parts from
the seat or disconnec t wires from it.
- Never carry sharp objects in you r pockets
or place t hem on the seat. If the weight­
sens ing ma t in the passenge r seat is
punctured it cannot work properly .
- Neve r carry things on you r 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 co ntrol
un it.
- Never store items under the front pas­
senger seat. Parts o f the Advanced Air­
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper­ ly.
- Never p lace seat covers or rep lacement
upholstery that have not been specifica l­

A WARNING
Objects between you and the a irbag will
increase the risk of injury 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 th ings in your hands or on
yo ur lap when the vehicle is in use.
- Never transport items on or in the area
of the front passenge r seat. Objects
c ou ld move into the area of the front air­
bags dur ing braking or other s udden ma­
neuver and become dange rous projec ­
tiles that can cause serious personal in­
jury if the airbags inflate.
- Never place o r attach accessories or oth­
er objects (such as cup ho lders, tele­
phone brackets, large, heavy or b ulky ob­
jects) on the doors, over or near the area
marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those a reas and yourself. These
objects co uld cause injury in a crash, es­
pecially when the airbags inflate.
- Never recline the front passenger's seat
to transport objects. Items can also
move in to the area o f the side airb ag or
the front airbag dur ing braking or in a
sudden maneuver. Objects near the air -
-
bags can become projectiles and cause
inju ry, partic ularly when the seat is re­
clined.
A WARNING
The fine dust created when airbags deploy
can cause breathing prob lems for people
with a history of asthma or other breath­
i ng cond itions.
- To reduce the risk of breath ing problems,
those with asthma o r othe r respiratory
conditions shou ld get fresh air righ t
away by getting o ut of the ve hicle or
open ing win dows or doors.
- I f you are i n a collision in which airbags
deploy, wash your hands and fa ce with
mild soap and wate r before ea ting.
- Be ca reful not to get the dust into your
eyes, o r into any c uts or s cratches.
- If the res id ue should get into your eyes,
flush them w ith wate r.

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An a irbag system that is not functioning
p roperly cannot p rovide supplemental pro­
tection in a frontal c rash.
- If the airbag ind icator light comes on, i t
means that there may be something
wrong with t he Advanced Airbag System.
It is poss ible that the ai rbag w ill inflate
when it is not supposed to, or will not in­
f late when it sho uld .
- Have the airbag system inspected imme­
d iate ly by yo ur Audi dealer.
A WARNING
If the front airbag inflates, a child without
a child restraint, in a rea rward-facing child
safety seat or in a forward-facing child re­
straint that has not been properly installed
will be serious ly injured and can be killed.
- Even tho ugh your vehicle is equipped
with an Advanced A irbag System, make
certain that all children, espec ially 12
yea rs and younger, always ride properly
restrained fo r their age and size.
-

122 Airbag sys te m
- Never modify t he front bumper or parts
of the veh icle body .
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­

backs that have not been spec ifi cally
approved by A udi.
- Never use add itiona l seat cushions that
cover the areas whe re the side airbags
inflate .
- D amage to the o rigina l 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 . Afte r an airbag has inf lated, it
must be replaced by an author ized Audi
dealer or qualified technic ian who has
the techn ica l information, tra ining and
special equipment necessary.
- The airbag system can be deployed only
once. After an a irbag has been deployed,
it must be replaced w ith new replace ­
ment parts designed and approved espe­
cially for your Aud i model version. Re­
placement of complete a irbag systems
or airbag componen ts must be per­
formed by qualified workshops only .

· Other things that can affect Advanced
Airbag performance
Chang ing the veh icle's suspens io n system can
change the way that the Advanced Airbag Sys­
tem perfo rms in a c rash. For examp le, using
t ir e- rim combinat ions not approved by A udi ,
lower ing the veh icle, c hanging the st iffness of
the suspens ion, including the spr ings, suspen­
sio n struts, shock absorbers etc . can change
the forces that ar e measured by the airbag
sensors and sent to the electronic contro l
unit. Some suspension changes can, for exam­
ple, increase the force levels measured by the
senso rs and make the airbag system deploy in
c rashes in which it wou ld no t deploy if the
c h anges had not been made. Other kinds of
c h anges may reduce the fo rce leve ls meas ­
u red by the sensors and p reven t the airbag
from dep loying when it should.
A WARNING
Changing the vehicle's suspension includ­
i ng use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
fo rmance and increase the r isk of serious
personal injury in a crash .
- Never install suspension components
that do not have the same performance characterist ics as the components origi ­
na lly installed on your vehicle .
- Never use tire-rim combinations that
have no t been approved by Audi.

_& WARNING
Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong informat ion to the electronic con­
trol modu le and prevent the Advanced A ir­
bag System from working properly.
- Always make sure that noth ing ca n inte r­

Knee airbags
Description of knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
F ig . 11 4 Drive r's a irbag
The driver knee a irbag is in the instrument
panel underneath the steering whee l
~ fig. 114, the airbag for the passenger is at
about the same height in the i nstrument pan­
e l underneath the g love compartment.
The knee airbag offers additiona l protection
to the driver's and passenger's knees and up­
per and lower thigh areas and supp lements
the protect ion by the safety be lts .
I f the front airbags deploy, the knee airbags
a lso deploy i n frontal collisions when the de­
p loyment threshold sto red in the cont ro l uni t
is met ~
page 117, More important things to
know about front airbags .
In addition to their normal safety function,
safety belts he lp keep the driver or front pas ­
senger in posit ion in a frontal coll is ion so that
A irba g sy stem 123
the ai rbags can provide supplemental protec­
tion .
T he airbag system is no t a subs tit ute for your
sa fety be lt . Rather, it is part of the overall oc­
cupant restraint system in your vehicle . A l­
ways remember that the airbag system can
only he lp 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
r::;, page 100, General notes .
Remember too, airbags will deploy on ly once
and only in certain kinds of accidents -your
safety belts are always there to offer protec­
t ion in those accidents in wh ich airbags are
not supposed to dep loy o r when they have al­
r eady deployed, for example when your vehi ­
cl e strikes or is struck by another after the
f irst collision.
This is just one of the reasons why an airbag is
not a s ubstitute fo r the safety be lt. The ai rbag
system works most effect ively when used with
the safety be lts. Therefore, always wear yo ur
sa fety belts correct ly .
It is impo rtant to remembe r that wh ile the
s u pplementa l knee airbag system is designed
to reduce the likelihood of ser ious inju ries,
other injur ies, for example, swelling, bru ising,
minor ab rasions and friction burns can a lso
occur when an airbag inflates.
The knee airbag system basically consists
of:
- The e lectronic control module
- Two in flatable ai rbags (a irbag and gas gen -
erator), one for the d river and one for the
front passenger
- The ai rbag indicator light in the instrument
panel
The knee airbag system will not deploy:
- when the ignit io n is t urned off
- in frontal collisions when the deceleration
meas ured by the control unit is too low
- in side co llisions
- in rear-end collisions
- in rollovers

-Always make 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
Q page 129, Child Safety.
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained front seat occupants.
Fig . 116 Side airbag location in the driver 's seat
The s ide airbags are located in the sides of the
front seat backrests
¢ fig. 116facing the
Airbag system 125
doors. They are identified by the word "AIR­
BAG".
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
- the airbag warning light in the instrument
cluster.
The airbag system is monitored electronically
to make certain that it is functioni ng 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 side airbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the driver's and front passenger's up ­
per torso on the s ide of the vehicle that is
struck in a side collision. The airbag deploys in
side impacts and only when the vehicle accel­
eration registered by the control unit is high
enough. If this rate is below the reference val­
ue programmed into the control unit, the side
airbags will not be triggered, even though the
car may be badly damaged as a result of the
collision . It is not possible to define an airbag
triggering range that will cover every possible
angle of impact, since the circumstances will
vary considerably between one collision and
another. Important factors include, for exam­
ple, the nature (hard or soft) of the impacting
object, the angle of impact, vehicle speed,
etc.
¢ page 127, Important safety instruc­
tions 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. Al­
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 is another reason why you should always wear
IIJJ,

126 Airbag system
your safety belts, not just because the law re ­
quires you to do so¢
page 100, General
notes.
It is impor tant to remember that while the
supp lemental side airbag system is designed
to reduce the likelihood of serious injuries,
other injuries, for example, swelling, bruising,
and minor abrasions can also be associated
with deployed side airbags. Remember too,
side airbags will deploy only once and only in
certain k inds of acc idents -your safety belts
are a lways there to offer protect ion.
Vehicle damage, repair costs or even the lack
of vehicle damage are not necessari ly an indi­
cation of over-sensit ive or failed airbag activa­
tion . In some co llisions, both front and s ide
a irbags may inflate. Remember too, that air­
bags will deploy only once and only in certa in
kinds of co llisions -your safety belts are al­
ways there to offer protection in those acci­
dents in which airbags are not supposed to
deploy or when they have already deployed.
The side airbag system will not depl oy:
- when the ign ition is turned off
- i n s ide collisions when the accelerat ion
measured by the sensor is too low
- i n rear-end collisions
- in rollovers.
In some types of accidents the front airbags
and side airbags may be triggered together.
A WARNING
-Safety belts and the a irbag system will
only prov ide protection when occupants
are in the p roper seating posit ion
~page 127.
-If the airbag indicator light comes on
when the veh icle is being used, have the
system inspected immediately by your
au thori zed Audi dealer. The a irbag may
not work properly when the vehicle ac­
celeration in a side co llision is h igh
enough to activate the airbag.
-
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.
F ig . 1 17 Inflated side airbags on left side of veh icle
When the system is triggered, the airbag is
filled with propellant gas and breaks through a seam in the seat surface area marked "AIR­
BAG".
It expands between the side trim panel
and the passenger. In order to help provide
th is additional protection, the side airbag
must inflate w ithin a fraction of a second at
very h igh speed and with great force. The sup­
pleme nta l side airbag could injure you if your
seat ing pos it ion is not proper or upright or if
items are loca ted in the area where the s up­
plementa l side airbag expands. This applies
especially to children¢
page 129, Child Safe­
ty .
Supplemental side airbags inflate between
the occupant and the door panel on the side
of the vehicle that is struck in certain side col­
lis ion ¢
fig. 117.
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 upper
part of the body.
A fine dust may deve lop when the airbag de­
ploys. 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. Al­
ways properly wear safety belts and ride in a
proper seating position.
There is a lot that you and your passengers
must know and act accordingly to help the
safety belts and airbags do their job to pro­
vide supplemental protection .
A WARNING
An inflating side airbag can cause serious
or fatal injury. Improperly wearing safety
belts and improper seating positions in­
crease the risk of serious personal injury
and death whenever a vehicle is being
used .
- In order to reduce the risk of injury when
the supplemental side airbag inflates:
-Always sit in an upright position and
never lean against the area where the
supplemental side airbag is located.
- Never let a child or anyone else rest
their head against the side trim panel
in the area where the supplemental
side airbag inflates.
- Always make sure that safety belts are worn correctly,
- Do not let anyone sitting in the front
seat put their hand or any other parts
of their body out of the window.
- 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
deploy.
- 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.
Airbag system 127
- Objects between you and the airbag can
increase the risk of injury in an accident
by interfering with the way the airbag
unfolds or by being pushed into you as
the airbag inflates.
- Never place or attach accessories or
other objects (such as cup holders, tel­ ephone brackets, or even large, bulky
objects) on the doors, over or near the
area marked "AIRBAG" on the seat backrests .
- Such objects and accessories can be­ come dangerous projectiles and cause injury when the supplemental side air­
bag deploys.
- Never carry any objects or pets in the
deployment space between them and
the airbags or allow children or other passengers to travel in this position .
- Always prevent the side airbags from be ­
ing damaged by heavy objects knocking
against or hitting the sides of the seat­ backs.
- The airbag system can only be triggered
once . If the airbag has been triggered,
the system must be replaced by an au­
thorized Audi dealership.
- Damage (cracks, deep scratches etc.) to
the original seat covers or to the seam in
the area of the side airbag module must
always be repaired immediately by an au­

130 Child Safety
8_ WARNING
If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
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 manufacturer's in­
structions 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 airbag as possible before installing
the child restraint. The backrest must be adjusted to an upright position.
- Always make sure that the

AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time your
vehicle was manufactured.
The Advanced Airbag system in your vehicle
has been certified to meet the "low-risk " re­
quirements for 3- and 6-year old children on
the passenger side and small adults on the
driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the 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 "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front
passenger seat in child restraints that are list­
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system, a child should al­
ways ride in the seat properly restrained for
its age and size. The airbag on the passenger
side makes the front seat a potentially dan­
gerous place for a child to ride. The front seat
is not the safest place for a child in a forward­
facing child safety seat. It can be a very dan­
gerous place for an infant or a larger child in a
rearward-facing seat.
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in your vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us­
ing the weight-sensing mat in the seat cush­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight-sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger
seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the
seat. The weight of a child restraint and its
"footprint" vary for different kinds of child re­
straints and for the different models of the
same kind of child restraint offered by child
restraint manufacturers.
The weight ranges for the individual types,
makes and models of child restraints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in­
fants and typical 1 year-old child have been
stored in the control unit of the Advanced Air­
bag System. When a child restraint is being
used on the front passenger seat with a .,..
