A WARNING ,~
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 inflates - even with an Advanced Airbag
System.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, door
or roof.
- 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 be­
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating position and have the airbag system
inspected by your authorized Audi dealer.
- Forward-facing child safety seats installed
on the front passenger's seat may interfere
with the deployment of the airbag and cause serious personal injury to the child .
A WARNING
If, in exceptional circumstances, you must in­
stall 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 man­
ufacturer for use on a front seat with a pas­
senger front and side airbag.
- Never put the forward-facing child restraint
up against or very near the instrument pan­
el.
- Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possible before installing the for­
ward-facing child restraint. The backrest must be adjusted to an upright position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.

A WARNING
To reduce the risk of serious injury, make sure
that the
PASSENGER AIR BAG OFF light will
be displayed whenever a child restraint is in­
stalled on the front passenger seat and the ignition is switched on .
- If the
PASSENGER AIR BAG OFF light does
not stay on, perform the checks described
~ page 142, Monitoring the Advanced Air­
bag System.
- Take the child restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the
PASSENGER AIR
BAG OFF
light does not stay on.
- Have the airbag system inspected by your
authorized Audi dealer immediately.
-Always carefully follow instructions from
child restraint manufacturers when instal­
ling child restraints.
A WARNING
If, in exceptional circumstances, you must in­
stall a forward or rearward-facing child re­
straint on the front passenger's seat:
- Improper installation of child restraints can
reduce their effectiveness or even prevent
them from providing any protection.
- An improperly installed child restraint can
interfere with the airbag as it deploys and
seriously injure or even kill the child -even
with an Advanced Airbag System.
-Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
- Never place additional items on the seat
that can increase the total weight registered
by the weight-sensing mat and can cause in­
jury in a crash.

Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occu­
pants .
Fig. 147 Location of driver airbag : in steering whee l
Fig. 148 Location of front passenger's airbag: in the instru­
ment panel
Your vehicle is equ ipped with an "Advanced Air­
bag System" in compliance with Un ited States
Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicab le at the time your veh i­
cle was manufactured. The safety belts for the
seats have "pretensioners" that help to take s lack
out of the belt system . The pretensioners are also
activated by the electronic control unit for the
airbag system .
The front safety belts a lso have load limiters to
help reduce the forces applied to the body in a
crash.
The airbag for the driver is in the steer ing wheel
hub ¢
fig. 147 and the airbag for the front pas ­
senger is in the instrument panel¢
fig. 148. The
general location of the airbags is marked "AIR­
BAG".

There is a lot you need to know about the airbags
in your vehicle . We urge you to read the detailed
i nformation about airbags, safety belts and child
safety in this and the other chapters that make
up the owner's literature. Please be sure to heed
the WARNINGS -they are extremely important
for your safety and the safety of your passengers, especially infants and small children .
,&_ WARNING -
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only supp lemental protection.
- Airbag work most effectively when used with properly worn safety belts .
- Therefore, always wear your safety be lts and
make sure that everybody in your vehicle is
properly restrained.
,&_ WARNING
A person on the front passenger seat, espe­
cially infants and small ch ild ren, will rece ive
serious i njuries and can even be killed by be­
ing too close to the airbag when it inf lates .
- Although the Advanced Airbag System in your vehicle is designed to turn off the front passenger airbag if an infant or a sma ll child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un­
der these special condit ions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle .
- The Advanced Airbag System can dep loy in
accordance with the "low risk" option under
the U .S. Federal Standard if a chi ld that is
heav ier than the typical one-year old child is
on the front passenger seat and the other
conditions for airbag deployment are met.
- Accident statistics have shown that ch ildren
are generally safer in the rear seat area than
in the front seating position .
- For their own safety, all children, especially
12 years and younger, sho uld a lways ride in
the back properly restrained for their age
and size .

Advanced front airbag system
Your vehicle is equipped w ith a front Advanced
Airbag System in compliance with United States
F ederal Motor Vehicle Safety Standard 208 asap­
plicable at the time your vehicle was manufac­
tured.
The front Advanced Airbag System supplements
the safety belts to provide additiona l protection
for the driver's and front passenger's heads and
upper bodies in frontal crashes. The airbags in­
flate only in frontal impacts when the vehicle de­
celeration is high enough.
The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety
be lts. Rather, it is part of the overall occupant re­
straint system in your vehicle. Always remember
that the airbag system can only help to protect
you, if you are sitt ing upright, wearing your safe­
ty belt and wearing it properly . This is why you
and your passengers must always be properly re­
strained, not just because the law requires you to
be.
The Advanced Airbag System in your veh icle has
been certified to meet the "low risk" require­
ments for 3 and 6 year-old children on the pas­
senger side and very small adults on the driver
side . The low risk deployment criteria are intend­
ed to help reduce the risk of injury through inter ­
action with the front airbag that can occur, for
examp le, by being too close to the steering whee l
and instrument panel when the airbag inflates.
I n addition, the system has been certified to
comp ly with the "suppression" requirements of
the Safety Standard, to turn
off the front airbag
for infants 12 months old and younger who are
restra ined on the front passenger seat in child re­
straints that are listed in the Standard
c::> page 154, Child restraints and Advanced Air­
bags.
"Suppression" requires the front airbag on the passenger side to be turned
off if:
- a ch ild up to about one year of age is restrained
on the front passenger seat in one of the rear­
facing or forward-fac ing infant restraints listed
in Federa l Motor Veh icle Safety Standard 208
Airbag system
with which the Advanced Airbag System in your
vehicle was certified. For a listing of the child
restraints that were used to certify your veh i­
cle's compliance with the US Safety Standard
c::>page 154,
- weight less than a thresho ld level stored in the
control unit is detected on the front passenger
seat.
When a person is detected on the front passen ­
ger seat, weighing more than the tota l weight of
a child that is about 1 year old restrained in one
of the rear-facing or forward-facing infant re­
stra ints (listed in Federal Motor Vehicle Safety
Standard 208 with which the Advanced Airbag
System in your veh icle was certified), the front
airbag on the passenge r side may or may not de­
ploy.
The
PASSENGER AIR BAG OFF light comes on
whe n the electronic contro l unit detects a total
weight on the front passenger seat that requires
the front airbag to be turned
off. If the PASSEN­
GER AIR BAG OFF
light does not come on, the
front airbag on the passenger side has not been
turned
off by the control unit and can deploy if
the control un it senses an impact that meets the
condit ions stored in its memory.
If the total weight on the front passenger seat is
more than that of a typical 1 year-old, but less
than the weight of a small adult, the front airbag on the passenger s ide may deploy (the
PASSEN­
GER AIR BAG OFF
light does not come on).
For example , the airbag may deploy if:
- a small child that is heav ier than a typical 1
yea r-old chi ld is on the front passenger seat (re ­
gardless of whether the chi ld is in one of the
child safety seats listed
c::> page 154),
- a child who has outgrown child restraints is on
the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light in the center of
the instrument panel wi ll come on and stay on.
T he front airbag on the passenge r sid e may
not
deploy (the PASSENGER AIR BAG OFF light does
not illuminate and stay lit) if: .,..

Airbag syste m
-a small adu lt or teenager is on the front pas ­
senger seat
- 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 req uires the airbag to meet the " low
risk" deployment criteria to help reduce the risk
of injury through interaction with the airbag .
"Low risk" deployment occurs in those crashes
that take place at lower decelerations as defined in the electron ic control unit.¢ page

Alw ays re member: Even though your vehicle is
equ ipped w ith Advanced Airbags, the safest place
for children is properly restrained on the back
seat . Please be sure to read the important infor ­
mat ion in the sections that follow and be sure to
heed a ll of the WARNINGS.
_& WARNING
To reduce the ris k of injury when an airbag in­
fla tes, always wear safety belts proper ly.
- If you are unrestrained, leaning fo rward, s it­
t ing s ideways or out of position in any way,
your risk of injury is much higher .
- You w ill also receive serious inju ries and
could even be killed if you are up against the
airbag or too close to it when it inflates -
even with an Advanced Airbag¢ page
132.
_& WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
ser iously injured and can be killed if the front
airbag inflates - even w ith an Advanced Airbag
System.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the front
airbag when a rearward -facing child re­
straint has been installed on the front pas­
senger seat, nobody can absolutely guaran­
tee that deployment is impossible in al l con­
ceivable s ituations that may happen dur ing
the usef ul life o f your vehicle .
- The inflating a irbag w il l hit the child safety
seat or infant carrier wi th great force and
138
w ill smash the child safety seat and child
aga inst the backrest, center armrest, door,
or roof.
- Always install rearward-facing chi ld re­
straints in the back seat.
- If you must insta ll a rearward fac ing ch ild
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PAS SENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating position and have the airbag system
inspected by your au thorized Aud i dealer .
_& WARNING
If, in exceptiona l circumstances, you must in­
stall a forwa rd-facing child restra int on the
front passenger's seat:
- Always ma ke sure the forward-facing sea t
has been des igned and certif ied by its man ­
ufacturer for use on a front seat with a pas­
senger front and s ide a irbag .
- Never p ut the fo rward-facing child restraint
up against or very near the instrument pan ­
el.
-Always move the passenger seat into its
rearmost position in the seat's fore and aft
ad justment range, as far away from the a ir­
bag as poss ible, before insta lling the for­
ward-facing child restraint. The backrest
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
whenever the ign it ion is switched on.
Advanced Airbag System components
The front passenger seat in your vehicle has a lot
of ve ry impo rtant parts of the Advanced A irbag
System in it. These pa rts include the we ight ­
sensing mat, senso rs, w iring, bracke ts, and more.
The function of the system in the front passenge r
seat is checked by the e lectronic control unit
when the ignition is on. The control unit mon itors
the Advanced Airbag System and turns the airbag i ndicator light on when a malfunct io n in the sys­
tem components is detected. The function of the
a irbag indicator light is described in greate r

detail below . Because the front passenger seat
contains important parts of the Advanced Airbag
System, yo u must take care to prevent it from be­
ing damaged. Damage to the seat may prevent
the Advanced Airbag for the front passenger seat
from do ing its job in a crash .
The front Ad vanced Airb ag S ystem con sis ts
of the following :
-Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration to
provide information to the Advanced Airbag
System about the severity of the crash .
- An electronic control unit, with integrated
crash sensors for front and side impacts . The
control unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors . T he control un it also "de­
cides" whether the safety be lt pretensioners
sho uld be activated.
- An Advanced Airbag with gas generator and
control valve for the driver inside the steering
whee l hub.
- An Advanced Airbag with gas generator and
control valve inside the instrument panel for
t h e front passenger.
- A weig ht-sensing mat under the upholstery
padding of the front passenger seat cushion
that meas ures the tota l weight on the seat. The
information registered is sent cont in uous ly to
the e lectronic control unit to regulate dep loy­
ment of the front Advanced Airbag on the pas­
senger side.
- An airbag monitoring system and indicator
light in the instrument cluster
¢ page 142.
-A sensor in each front seat registers the dis­
tance between the respect ive seat and the
steering wheel or instrument panel. The infor­
mation registered is sent cont inuously to the
elect ron ic cont ro l unit to regulate deployment
of the front Advanced Airbags.
- T he
PASSENGER AIR BAG OFF light comes on
and stays on in the center of the i nstrument
pane l¢
page 142, fig . 150 and tells you when
the front Advanced Ai rbag on the passenger
side has been turned
off .
-A sensor below the safety belt la tch fo r the
front seat passenge r to measure the tension on
Airbag syste m
the sa fe ty belt. The tens ion on the safety be lt
and the weight registe red by the weight -sens­
ing mat help the control unit "decide" whether
the front a irbag for the front passenger seat
should be turned
off or not¢ page 133, Child
restraints on the front seat- some important things to know.
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transm its this informat ion to the elect ro nic
cont ro l unit.
A WARNING
D amage to the fron t passenger seat can pre­
vent the fron t air bag from working prope rly.
- Imp roper repai r or d isassembly of the front
passenger and driver sea t will prevent the
Advanced Airbag System from functioning properly .
- Repairs to the front passenge r seat must be
performed by qualified and p roperly trained
workshop personne l.
- Never remove the front passenger or driver seat from the vehicle .
- Never remove the upho lstery from the front
passenger seat.
- Never d isassemble o r remove par ts from the
seat or disconnect w ires from it.
- Never carry sh arp objects in yo ur po ckets or
p la ce them on t he seat.
If the weight-sens­
ing mat in the passenger seat is punctu red
it cannot work properly .
- Never carry things on yo ur lap or carry ob ­
jects on the passenger seat. S uch items can
increase the we ight registe red by the
weight-sensing mat and send the wrong in­
formation to the a irbag control unit.
- Never store items under the front passenger
seat . Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, p reventing them and the airbag sys­
tem from wo rking prope rly.
- Never p lace seat covers or rep lacement up­
holstery that have not been specifically ap­
p roved by Aud i on the front seats.
- Seat cove rs can prevent the Advanced Air­
bag Sys tem from recogniz ing child
1 39

Airbag system
restraints or occupants on the front passen­
ger seat and prevent the side airbag in the
seat backrest from deploying properly.
- Never use cushions, pillows, blankets or
similar items on the front passenger seat.
The additional padding will prevent the
weight-sensing mat in the seat from accu­ rately registering the child restraint or per­
son on the seat and prevent the Advanced
Airbag System from functioning properly.
- If you must use a child restraint on the front
passenger seat and the child restraint man­
ufacturer's instructions require 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 restraint is installed on the front pas­
senger seat.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in­
stall child restraint in a rear seating position
and have the airbag system inspected by
your authorized Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
airbags supplement the protection offered by the
front three-point safety belts with pretensioners and load limiters and the adjustable head re­
straints to help reduce the risk of injury in a wide
range of accident and crash situations. Be sure to
read the important information about safety and
heed the WARNINGS in this chapter.
Deployment of the Advanced Airbag System and
the activation of the safety belt pretensioners de­
pend on the deceleration measured by the crash
sensors and registered by the electronic control
unit . Crash severity depends on speed and decel­
eration 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 amount pro­
grammed in the electronic control unit . The front
140
airbag on the passenger side will also be turned
off if one of the child safety seats that has been
certified under Federal Motor Vehicle Safety
Standard 208 has been recognized on the seat.
The
PASSENGER AIR BAG OFF light comes on
and stays on to tell you when the front Advanced
Airbag on the passenger side has been turned off
¢ page 133, Child restraints on the front seat ­
some important things to know .
.&_ WARNING
To reduce the risk of injury when an airbag in­
flates, always wear safety belts properly.
- If you are unrestrained, leaning forward, sit­
ting sideways or out of position in any way,
your risk of injury is much higher.
- You
will also receive serious injuries and
could even be killed if you are up against the
airbag or too close to it when it inflates -

More important things to know about front
airbags
Fig. 149 Inflated front airbags
-,... N 0 :i: ;;i;
Safety belts are important to help keep front seat
occupants in the proper seated position so that
airbags can unfold properly and provide supple­
mental protection in a frontal collision.
The front airbags are designed to provide addi­
tiona l protection for the chest and face of the
driver and the front seat passenger when:
- safety belts are worn properly,
- the seats have been positioned so that the oc-
cupant is properly seated as far as possible
from the airbag, .,._

M N
ci u.. co ,...., \!) ..,.,
N ..,., ,....,
-and the head restraints have been p roperly ad -
justed.
Because airbags inflate in the blink of an eye w ith
great force, things you have on yo ur lap o r have
p laced on the seat cou ld become dangerous p ro­
jectiles, and be pushed into yo u if the airbag in­
flates.
When an a irbag deploys, fine dust is released.
This is normal and is not caused by a fire in the
vehicle. This dust is made up mostly of a powder
used to lubricate the airbags as they dep loy. It
could irr itate skin.
It is important to remember that whi le the sup ­
p lemental airbag system is designed to reduce
the likelihood of serious in juries, other injur ies,
for example swell ing, bruising and minor abra­
sions, can also happen when a irbags inf late. Air­
bags do not protect the arms or the lower parts
of the body. Front airbags o nly supplement the
three point safety belts in some frontal col lisions
i n which the veh icle deceleration is high enough
to deploy the airbags.
F ront airbags will not deploy:
- if the ign it io n is switched off when a crash oc -
curs,
- in s ide collisions,
- in rear-end collisions,
- in ro llovers,
- when the crash deceleration measured by the airbag system is less than the minimum thresh ­
o ld needed for airbag deployment as registered
by the electronic control un it.
Th e front pa ssenger airbag will al so not
depl oy:
-when the front passenger seat is not occupied,
- when the weight on the front passenger seat as
sensed by the Advanced Airbag System indi­
cates that the front airbag on the passenger
s ide has to be turned off by the electronic con­
trol unit (the
PA SSENGER AIR BAG OFF light
comes on and stays on) .
A WARNING
Sitting in the wrong position can increase the
risk of se rious injury in crashes .
Airbag syste m
- To reduce the risk of injury when the airbags
inflate, the driver and passengers must al­
ways sit in an upright pos ition, must not
lean aga inst 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 position
or too close to the airbag can be seriously
in ju red by an a irbag as it unfo lds with great
for ce in the blink ofan eye
Qpage 133.
A WARNING
A child in a rearward-fac ing ch ild safety sea t
i nsta lled on the front passenger seat w ill be
se riously inju red and can be killed if the front
a irbag inflates - even with an Advanced Airbag
System .
- The inflating airbag will hit the child safety
seat o r infant carrier with great force and
will smash the child safety seat and child
aga inst the backrest, center armrest, door
or roof.
- Always install rear-fac ing ch ild safety seats
on the rear seat.
- If you must install a rearwa rd fac ing child
safety seat on the front passenger seat be­
cause of except ional circumstances and the
PASS ENG ER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating posi tion and have the airbag system
inspected by your authori zed Audi dealer .
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfe r­
ing with the way the airbag unfolds or by be ­
ing p ushed into you as the airbag inflates .
- Never hold things in yo ur hands or on your
lap when the vehicle is in use .
- Never transpo rt items on or in the a rea of
the front passenger seat. Objects could move into the area of the front airbags dur­
ing brak ing or other sudden maneuver and
become dangerous project iles that can
cause serious persona l injury if the a irbags
inflate.
141

Airb ag syst em
-Never place or attach accessories or other
objects (such as cupholders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked "AIRBAG" on the steer ing wheel, instru­
ment pane l, seat backrests or between
those areas and yourself. These obje cts
could cause injury in a crash, e specially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objec ts . Items can also move into
t h e area of the side airbag or the front air ­
bag dur ing braking or in a sudden maneu·
ver. Objects near the airbags can become
projectiles and cause injury, part icularly
when the seat is reclined.
A WARNING
The f ine dust created when a irbags dep loy can
cause breathing problems for people with a
history of asthma or other breathing condi­
tions .
- To reduce the r isk of breathing problems,
those w ith asthma or other resp iratory con­
ditions should g et fr esh air r ight away by
get ting out of the vehicle o r opening w in ­
dows or door s.
- If you are in a col lision in w hich a irbags de­
p loy, wash your hand s and fa ce wi th mild
soap and water before eating.
- Be caref ul not to get the dus t into you r eyes,
or into any cuts or s cratches.
- If the residue should get into you r eyes,
flush them with water.
Monitoring the
Advanced Airbag System
Airbag monitoring indicator light
Two separa te indicators monitor the function of
the Advanced Airbag System: the airbag moni­
toring indicator light and the
PASSENGER AIR
BAG OFF
light.
The Advanced Airbag System (including the elec· tronic control unit, sensor circuits and system
w iri ng) is monitored cont inuous ly to make sure
that it is funct ion ing properly whenever the ign i·
142
tion is on . Each time you t urn on the ignit ion, the
fl airbag monitoring indicator light wi ll come on
for a few seconds (self diagnostics).
The sy stem must be inspected when th e II
indicator light :
-does not come on when the ignition is sw itched
on,
- does not go out a few seconds after you have
switched on t he ignit ion, or
- comes on wh ile driving.
If an airbag system malfunction is detected, t he
i ndic ator light will fi rst s tart flashing to catch the
dr ive r's at ten tion and the n stay on con tinuou sly
to serve as a constant reminder to have the sys ­
tem inspected immediately .
If a malfu nction occurs that turns the front air ­
bag on the passenge r side off, the
PASSENGER
AIR BAG OFF
light will come on and stay on
whenever the ignit ion is on .
A WARNING
An airbag system that is not functioning prop­
erly cannot provide supp lemental protection
in a frontal crash.
- If the airbag ind icator light
c> page 19
comes when the vehicle is being used, have
the system inspected immediately by your
author ized Audi dealer .
It is possible that
the airbag will inflate when it is not sup·
posed to, or will not inflate when it should.
