greater detail below. Because the front passen­
ger seat contains important parts of the Ad­
vanced A irbag System, you must take care to pre ­
vent it from being damaged. Damage to the seat may prevent the Advanced Airbag for the front
passenger seat from doing its job in a crash .
The front Ad vanced Airb ag S ystem con sis ts
of the follo wing :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/decelerat io n 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
contro l unit "decides" whethe r to fire the front
airbags based on the information received from
the crash sensors. The control unit also "de ­
cides" whether the safety be lt pretensioners
shou ld be activated.
- An Advanced Airbag with gas generator and
contro l valve for the driver inside the steering
whee l hub .
- An Advanced Airbag with gas generator and
contro l valve inside the instrument pane l for
the front passenger.
- A weight -sensing mat under the upho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat . The
information registered is sent continuously to
the e lectron ic control unit to regulate dep loy­
ment of the front Adva need A irbag on the pas ­
senger side.
- An airbag monitoring system and indicator
light i n the instrument cluster
¢ page 122.
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation reg istered is sent cont inuous ly to the
electronic control unit to regulate deployment
of the fro nt Adv a need A irbags.
- T he
PASS EN GE R AIR BAG OFF light comes on
and stays on in the center of the instrument
pane l¢
page 122, fig . 124 and tells you when
the front Advanced Airbag on the passenge r
side has been turned off.
- A sensor below the safety belt latch fo r the
front seat passenger to meas ure the tension on
Airb ag sys tem
the sa fety belt. The tension on the safety belt
and the weight registered by the weight-sens­
ing mat help the contro l unit "decide" whether
the front airbag for the front passenger seat should be turned off or not¢
page 113, 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
transmits this information to t he electronic
cont rol un it.
_& WARNING
Damage to the front passenge r seat can pre­
vent the front airbag from working properly.
- Imp roper repair or disassembly of the front
passenger and driver seat will p revent the
Advanced Airbag System from f unctioning
p roperly.
- Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personne l.
- Never remove the front passenger or driver
seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
- Never d isassemble o r remove par ts from the
seat o r disconnect w ires from it.
- Never carry sh arp objects in your pocke ts or
p lace them on the seat. If the weight-sens­
ing mat in the passenger seat is punctu red
it cannot work proper ly.
- Never carry things on your lap or carry ob­
jects on the passenger seat. S uch items can
increase the weight reg istered 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 working p roper ly.
- Never p lace seat covers or replacement up­
holstery that have not been specifically ap­
p roved by A udi on the front seats.
- Seat covers can prevent the Advanced A ir­
bag System from recognizing chi ld
119

Airbag syste m
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-sens ing mat in the seat from accu­
rately reg istering the ch ild restraint or per­
son on the seat and prevent the Advanced
Airbag System from funct ioning prope rly.
- If you must use a child restraint on the front
passenge r seat and the child restraint man­
ufact urer's instructions require the use of a
towel, foam cushion or something else to properly position the chi ld restraint, make
certain that the
PASSENGER AIR BAG O FF
light comes on and stays on whenever the
child restraint is installed on the front pas­
senger seat.
- If the
PASSENGER AIR BAG O FF light does
not come on and stay on, immediately in­
stall child restrai nt in a rear seating position
and have the airbag system inspected by
you r authorized Aud i deale r.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
ai rbags supplement the protection offered by the
front three-point safety belts with pretensioners and load limiters and the adjustable head re ­
stra ints to help reduce the r isk 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 th is chapter .
Dep loyment 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
era tion as we ll as the mass and stiffness of the
vehicle or object invo lved in the crash.
On the passenger s ide, regardless of safety belt
use, the a irbag will be t urned off if the weight on
the passenge r seat is less than the amount p ro­
g rammed in the e lectron ic cont rol unit . T he front
120
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 recogn ized on the seat.
The
PAS SEN GER AI R BA G OFF light comes on
and stays on to te ll you when the front Advanced
Airbag on the passenger side has been turned off

.&_ WARNING
To reduce the risk of injury when an airbag in­
f lates, always wear safety belts properly.
- I f you are un restrained, leaning forward, sit­
ting sideways or ou t of position i n any way,
your ris k of injury is much highe r.
- You will a lso receive ser ious injuries and
could even be killed if yo u are up against the
airbag or too close to i t when it inflates -
even with an Advanced Airbag

More important things to know about front
airbags
Fig. 123 Inflated front a irbags
Safety be lts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfo ld properly and prov ide sup­
plemental protection in a fronta l co llision.
The front airbags a re designed to provide addi­
tional protection for the chest and face of the driver and the front seat passenger when:
- safety belts are worn properly,
- t he seats have been positioned so that t he oc-
cupant is properly seated as far as possib le
from the airbag,
Ill-

-and the head restraints have been properly ad -
justed.
Because airbags inflate in the blink of a n eye w ith
great for ce, things you have on you r lap or have
p laced on the seat cou ld become dangerous pro ­
jectiles, and be pushed into you 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 deploy. It
could irr itate skin.
It is important to remember that while the sup­
p lemental airbag system is designed to reduce
the likelihood of ser ious injuries, other inj uries,
for example swell ing, bruising and minor abra­
sions, can also happen when airbags inflate. Air­
bags do not protect the arms or the lower parts
of the body . Front airbags only supplement the
three po int safety belts i n some fronta l co llisions
i n which the veh icle decelerat ion is high enough
to deploy the airbags.
F ront airbags will not deploy:
- if the ignit ion is switched off when a crash oc -
curs,
- in s ide collisions,
- in rear-end collisions,
- in rollovers,
- when the crash decelerat ion measured by the
airbag system is less than the minimum thresh­
o ld needed for airbag deployment as registered
by the electronic contro l unit .
Th e front passeng er airbag will a lso not
deplo y:
- 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
P A SSENGER AIR B AG OFF light
comes on and stays on).
A WARNING
Sitting in the wrong pos ition can increase the
r isk of se rious injury in c rashes.
Airb ag sys tem
-To reduce the risk of injury when the ai rbags
inflate, the driver and passengers must al­
ways sit in an upright posit ion, must not
lean aga inst or place any part of their body
too close to the area where the airbags are located.
- Occupants who are unbelted, out of posit ion
or too close to the airbag can be seriously in jur ed by an airbag as it unfolds with g reat
for ce in the blink of an eye
Qpage 113.
A WARNING
A child in a rearward-facing child safety seat
i nsta lled on the front passenger seat will be
seriously injured and can be k illed if the front
a irbag inflates - even with an Advanced Airbag
System .
- The inflating airbag will hit the child safety seat or infant ca rrier 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 child safety seats
on the rear seat.
- If you must install a rea rwa rd facing child
safety seat on the front passenger seat be ­
cause of exceptional circumstances and the
PA SS ENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rea r-facing child safety seat in a rear
seating position and have the a irbag system
inspected by your au thori zed A udi dealer.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
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 transport items on or in the area o f
the front passenger seat . Objects could
move into the area of the front airbags dur­
ing braking or other sudden maneuver and
become dangerous projectiles that can
cause serious persona l injury if the airbags
inflate.
121

Airbag syste m
-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 steering wheel, instru­
ment panel, seat backrests or between
those areas and yourself. These objects
could cause injury in a crash, especially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objec ts. Items can also move into
the area of the side airbag or the front a ir­
bag dur ing braking or in a sudden maneu­
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined.
A WARNING
The f ine dust created when airbags deploy can
cause breath ing problems for people w ith a
history of asthma or other breathing condi­
t ions.
- To reduce the risk of breathing problems,
those w ith asthma or other respiratory con­
ditions should get fresh air right away by
gett ing out of the vehicle o r opening w in­
dows or doors.
- If you are in a collision in which airbags de­
ploy, wash your hands and fa ce with mild
soap and water befo re eat ing.
- Be careful not to get the dust into your eyes,
o r into any cu ts or sc ratches.
- If the resid ue should get into yo ur eyes,
flush them with water.
Monitoring the
Advanced Airbag System
!f Airbag monitoring indicator light
Two separate indicators monitor the function of
the Advanced Airbag System: the airbag moni­
toring indicator light and the
PA SSENGER AIR
BAG OFF
light.
The Advanced Airbag System as well as the side airbags and side curtain airbags with eject ion
mit igat ion features ( including the electronic con­
trol unit, sensors and system wiring) are all
122
monitored continuous ly to make sure that they
are functioning properly whenever the ignition is
on . Each time you turn on the ignit ion, the airbag
monitoring indicator light
m will come on for a
few seconds (se lf diagnostics) .
The system mu st be inspected wh en th e
indicat or light
E,I:
- does not come on when the ignition is switched
on,
- does not go out a few seconds after you have
switched on the ignit ion, or
- comes on while driving.
If an airbag system malfunc tion is detec ted, the
indicator light will first start flashing to catch the
driver's attention and then stay on continuously
to serve as a constant rem inder to have the sys­
tem inspected immediately.
If a malfunction occurs that turns the front air ­
bag on the passenger side off, the
PASSENGER
AIR BAG O FF
light will come on and stay on
whenever the ignition is on.
A WARNING
An airbag system that is not functioning prop­
erly cannot provide supplemental protect ion
in a frontal crash .
- If the airbag ind icator light
q page 16
comes when the veh icle is being used, have
the system inspected immediately by your
author ized Audi dealer. It is possib le that
the airbag will i nfla te when i t is no t sup­
posed to, or wi ll not inf late when it sho uld.

- 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.
I f the front passenger seat is no t occupied, the
fron t air bag w ill not deploy, and the
PASSENGER
AIR BAG OFF
light will stay on . Never install a

sure that the chi ld restraint is properly ins ta l­
led and that the safety belt for the front pas­
senger seat has bee n correct ly routed around
the child restraint as desc ribed in the c hild re­
straint manufacture r's instruct ions;
- make sure that the convertible locking retrac­
tor on the safety belt for the front passenge r
seat has been activated and that the safety belt
has been pulled tight. The belt must not be
loose or have loops of slack so that the sensor
below the safety belt latch on the seat can do
its job ¢
page 141 .
-make sure that th ings that may increase the
weight of the child and ch ild safety seat are not
be ing transported on the front passenger seat ;
- make sure that the safety belt tens ion sensor is
not b locked . Shake the safety belt la tch on the
front passenger seatback and fo rth ;
- 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 t hat i t causes the
weight-sensing mat to me asu re more weight
than is actua lly on the sea t.
If the PASSENGER AIR BAG OFF light still do es
not come on
and does not stay on co nti nuously
(whe n the ignition is switched on),
- take the child restraint off the front passenge r
seat and install it p roper ly at one of the rear

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 16
comes when the vehicle is be ing used, h ave
the system inspected immediate ly by yo ur
authorized Audi 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 restra int
that has not been properly installed w ill be
ser iously injured and can be killed .
124
-Even tho ugh your vehicle is equipped with
an Advanced A irbag System, make certain
that a ll 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 light 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 authorized 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-facing child res traint on
the front p assenge r seat, always move the
seat into i ts rearmost position in the sea t's
fore and aft ad justment range, as far away
from the ai rbag as possible . 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
wheneve r the ignit ion is switched on.
A WARNING
- If the PASSENG ER 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 inspected by your
author ized Audi dealer befo re t ransporting
anyone on the front passenger seat.

(D Tips
If the weight-sensing mat in the front passen­
ger seat detects an empty seat, the front air­
bag on the passenger side will be turned off,
and
P ASS ENGER AIR B AG OFF will stay on.
Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent p laces on your Aud i. Installing, remov­
ing, servicing o r repa iring a part in an area of the
vehicle can damage a pa rt of an airbag system
and prevent that system from working properly in a co llision.
There are some importa nt things you have to
know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
Improper care, serv icing and repair proce­
dures can increase the r isk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly :
-
-Never cover, obstruct, or change the steer­
ing wheel horn pad or a irbag cover or the in ­
strument panel or mod ify them in any way .
- Never attach any objects such as cupholders
or telephone mountings to the surfaces cov­
er ing the airbag units .
- For cleaning the horn pad or instrument panel, use only a soft, dry cloth or one mois­
tened with plain water. Solvents or cleaners
cou ld damage the a irbag cover or change
the stiffness or strength of the mater ial so
that the airbag cannot dep loy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All work on the stee ring wheel, instr ument
pane l, front seats or electrical system (in­
cluding the installation of audio equipment,
cellu lar telephones and CB radios, etc .)
must be performed by a qualified technician
Airb ag sys tem
who has the training and special equ ipment
necessary.
- For any wo rk on the airbag system, we
strong ly recommend that you see your au­
thorized Audi dealer or qualified workshop .
- Never modify the front bumper or parts of
the vehicle body.
- Always make sure that the side a irbag can
inflate without interference:
- Never install seat covers or replacement
upholstery ove r the front seatbacks that
have not been specifica lly approved by
Audi .
- Never use addi tional seat cushions that
cove r the areas where the side airbags in­
flate.
- 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 authorized Aud i dealer.
- The airbag system can be activated only
once . A fter an airbag has inflated, it must
be replaced by an authorized Audi dealer or
qualified technic ian who has the technical
information, training and spec ial equ ipment
necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed, it
must be replaced with new rep lacement
parts des igned and approved especially for
your Aud i model version. Replacement of
comp lete airbag systems or airbag compo­
nents must be performed by qualified work­
shops only. Ma ke sure that any airbag serv­
ice act ion is en tered in your Aud i Wa rranty
& Maintenance booklet under AIRBAG RE ­
PLACEMENT RECORD.
@ For the sake of the environment
Un deployed airbag modules and p retension-
ers might be classif ied 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 modu les safe-
ty belts with pretensioners are scrapped, all
applicable laws and regu lations must be ob­
se rved. Your authorized Audi dealer is familiar .,.
125

Airbag syste m
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 System
performs in a crash. For examp le, using t ire-r im
comb inat ions not approved by Audi, lower ing the
veh icle, changing the stiffness of the suspens ion,
including the springs, suspension 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 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 kinds of
changes may reduce the force levels meas ured by
the sensors and prevent 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 Airbag 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 instal­
led o n your veh icle .
- Never use tire-rim comb inations that have
not been approved by Audi.
A WARNING
Items stored between the safety belt buckle
and the center console can cause the senso rs
in the buckle to send the wrong info rmation
to the electronic control module and prevent
t he Advanced Airbag System from wor king
properly.
- Always make sure tha t noth ing can interfere
with the safety be lt buck les and that they
are not obstructed.

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants .
Fig. 125 S ide a irbag locat io n in the driver's seat
The side airbags are located in the sides of the
front seat backrests ¢
fig. 125 facing the doors.
They are identified by the word "AIRBAG".
The sid e airbag system ba sically con sis t s o f:
- the electronic control module and external side
impact sensors
- the two a irbags located in the s ides of the front
backrests
- the airbag warning light in the instrument clus -
ter.
The airbag system is monitored electronica lly to
make certain that it is functioning properly at a ll
t imes. Each time you turn on the ignition, the air ­
bag system indicator light w ill come on for a few
seconds (self diagnostics) .
The side airbag system supplements the safety belts and can help to reduce the risk of injury to
the driver's and front passenger's upper torso on
the side of the vehicle that is struck in a side co l­
li sion. The a irbag deploys only in side impacts
and only when the vehicle acceleration registered by the control unit is high enough. If this rate is
below the reference val ue programmed into the
contro l unit, the side airbags will not be trig-
gered, even though the car may be badly dam-
aged as a result of the collision. It is not possible
to define an airbag triggering range that will cov­ er every possible angle of impact, si nce the c ir­
cumstances w ill vary conside rably between one
collision and another . Important factors include, .,,.
