For exa mple , the ai rb ag ma y depl oy if:
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whe ther the child is in one of
the chi ld safety seats listed
¢ page 188),
-a ch ild who has outg rown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PA SSENGER AIR BAG OFF light in the cente r
of the instrument panel w ill come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PAS SENGER AIR BAG OFF
light does not ill uminate and stay lit) if:
- a small adult or teenager is on the front pas
senger seat
- a passenger who is not sitt ing upright wit h
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the seat is on the front passenger seat.
If the front passenge r airbag deploys, the
Federal Standard requires the airbag to meet
the "low risk" deployment criteria to help re
d uce the risk of inj ury through interaction
with the airbag. " Low risk" deployment occurs
in those crashes that take place at lower de
celerations as defined in the e lectronic control
un it.

Alw ays remember : Even though you r vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat . Please be sure to read the impor
tant information in the sect ions that follow
and be sure to heed a ll of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag
inf lates, always wear safety belts properly.
- 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 injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in- f
lates - even with an Advanced A irbag
¢page 162.
A WARNING
-A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be serious ly injured and can be killed if
the front airbag inflates - even with an Ad
vanced A irbag System .
- Although the Advanced Airbag System in your veh icle is designed to turn off the
front airbag when a rearward-facing child restraint has been instal led on the
front passenger seat, nobody can abso
lutely g uarantee that dep loyment is im
possible in all conceivable situations that
may happen during the usefu l life of your
veh icle.
- The inflating airbag will hit the c hild
safety seat or 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 rearward -facing ch ild re
straints in the back seat.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptiona l circumstan
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im
mediately insta ll th e rear-fac ing c hild
safety sea t in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer .
A WARNING
If, in exceptional circumstances, you m ust
insta ll 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 s ide a irbag.
- Never p ut the forward-facing child re
straint up against or very near the instru-
ment panel.
~
-Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before installing
the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime w henever the ignition is sw itched
on.
Advanced Airbag System components
The fron t passenger seat in your vehicle has a
lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sensing mat, sensors, wiring, brack
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on .
The control un it mon itors the Advanced Air
bag System and turns the airbag indicator
l ight on whe n a ma lfunction in t he sys tem
components is de tected. The function of the
airbag indicator light is described in greater
detai l below . Because the front passenger
seat contains important parts of the Ad
vanced A irbag System, you m ust take care to
prevent 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 Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/decele ration
to provide information to the Advanced Air
bag System about the seve rity of the crash.
- An electronic co ntrol unit, with integrated
c rash se nsors for front and side impacts .
T he cont ro l unit " decides " whethe r to fire
the front airbags based on the inform ation
received from the crash senso rs . The contro l
unit a lso "decides" whether the safety belt
pretensioners should be activated .

-Improper repair or disassembly of the
front passenger and driver seat will pre
vent the Advanced A irbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
dr iver seat from the veh icle .
- Never remove the upholstery from the
front passenger seat.
- Never disassemble or remove parts from the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or place them on the seat. If the weight
sensing mat in the passenger seat is punctured it cannot work properly.
- Never carry things on your lap or carry
objects on the passenger seat. Such
items can increase the weight registered
by the weight-sens ing mat and send the
wrong info rmation to the airbag control
unit.
- Never store items under the front pas·
senger seat. Parts of the Advanced Ai r
bag System under the passenge r seat
cou ld be damaged, prevent ing them and
the airbag system from wo rking proper
ly .
- Never place seat covers or replacement upholstery that have not been specifical
ly approved by A udi on the front seats.
- Seat covers can prevent the Advanced Airbag System from recognizing child re
straints or occupants on the front pas
senger seat and prevent the side airbag in the seat backrest from deploy ing prop
erly.
- Never use cush ions, pillows, blankets or
similar items on the front passenger
seat. The add itiona l padd ing will prevent
the weight-sensing mat in the seat from
accu rately reg iste ring the c hild restra int
or person on the seat and prevent the
Advanced Airbag System from function ing properly .
-If you must use a child restra int on the
front passenger seat and the ch ild re- straint manufacturer's instructions
re
qu ire the use of a towel, foam cushion or
something e lse to properly pos ition the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the ch ild re·
straint is installed on the front passen
ger seat.
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immed i
a tely insta ll child restrain t in a rear se at
ing 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
s ide airbags supp lement the protection of
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help redu ce the
risk of inju ry in a wide range of accident and
c rash situations. Be s ure to read the impor
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need A irbag System
and the activation of the safety belt preten
sioners depend on the deceleration measured
by the crash sensors and registered by the
electron ic control unit. The amount of infla
tion of the front airbags can a lso be adapted
to the front seat pos ition, depending on the
distance between the respect ive front seat
and the steer ing w heel or instrument panel as
registered by sensors in the seats. Crash se·
verity depends on speed and deceleration as
well as the mass and st iffness of the vehicle
o r object involved in the crash .
On the passenger side, regardless of safety
belt use, the ai rbag w ill be tu rned off if the
we ight on the passenger seat is less than the
amount programmed in the e lectronic control
u nit. The front airbag on the passenger side
will a lso be turned off if one of the child safe -
ty seats that has been certified under Federal Motor Vehicle Safety Standard 208 has been
recogni zed on the seat . The

A WARNING
To reduce the risk of injury whe n an airbag
inflates, always wear safety belts properly .
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, yo ur risk of injury is much highe r.

More important things to know about
front airbags
Fi g. 177 Inflated front a irbags
Safety belts are important to help keep front
seat occupants in the proper sea ted pos ition
so that airbags c an u nfo ld properly and pro
vide supp lemental protection in a fronta l co l
lision.
The front a irbags are designed to provide ad
d itiona l protection for the chest and face of
the dr iver and the front seat passenge r when:
- safety belts are worn properly,
- the seats have been posit io ned so that the
occupant is p roperly seated as far as possi
ble from the a irbag,
- and the head restraints have been properly
adjusted.
Because airbags inflate in the blink of an eye
with great force, things you have on your lap
A irba g sy stem 1 71
or have p laced on the seat co uld become dan
gerous projectiles, and be p ushed into you if
the a irbag inf lates.
When an airbag deploys, fine dust is re leased.
T his is norma l and is not caused by a fi re in
the ve hicle . 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 remembe r that wh ile the
supplementa l airbag system is designed to re
duce the like lihood of serious injur ies, other
injuries, for example swelling, bruis ing and
minor abrasions, can also happen when air
bags inflate . A irbags do not protect the arms
o r the lower parts of the body. Front a irbags
on ly supp lement the three point safety belts
in some fronta l co llisions in which the vehicle
decelera tion is high e no ugh to deploy the air
bags .
Front airbags will not deploy :
-if the ignition is sw itched off when a crash
occu rs,
- in side collisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measured by
the airbag system is less than the minimum
threshold needed for a irbag deployment as
reg istered by the electronic control unit .
The front pa sse n ger ai rbag will also not
deplo y:
- when the front passenger seat is not occu
pied,
- when the weight on the front passenger seat as sensed by the Advanced Airbag Sys·
tern ind icates that the front airbag on the
passe nger side has to be turned off by the
electronic control unit (the
PAS SENGER A IR
BAG OFF
light comes on and stays on) .
A WARNING
Sitting in the wrong position can increase
the r is k of se rious inj ury in crashes.
- To reduce the risk of injury when the air
bags inflate, the drive r and passenge rs
172 Airbag system
must always sit in an upright position,
must not lean against or place any part
of their body too close to the area where
the airbags are located .
- Occupants who are unbelted, out of posi
tion or too close to the airbag can be se riously injured by an airbag as it unfolds
with great force in the blink of an eye
~page 163.
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 Ad
vanced 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 because of exceptional circumstan
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer.
A WARNING
Objects between you and the airbag 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 airbag
inflates.
- Never hold things in your hands or on
your lap when the vehicle is in use.
- Never transport items on or in the area of the front passenger seat. Objects
could move into the area of the front air
bags during braking or other sudden ma
neuver and become dangerous projec- tiles that can cause serious personal in
jury if the airbags inflate.
- Never place or attach accessories or oth
er objects (such as cupholders, tele phone brackets, large, heavy or bulky ob
jects) on the doors, over or near the area marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be
tween those areas and yourself. These
objects could 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 into the area of the side airbag or
the front airbag during braking or in a
sudden maneuver. Objects near the air
bags can become projectiles and cause
injury, particularly when the seat is re
clined.
A WARNING
'-
The fine dust created when airbags deploy
can cause breathing problems for people
with a history of asthma or other breath
ing conditions.
- To reduce the risk of breathing problems, those with asthma or other respiratory
conditions should get fresh air right
away by getting out of the vehicle or
opening windows or doors.
- If you are in a collision in which airbags
deploy, wash your hands and face with
mild soap and water before eating.
- Be careful not to get the dust into your
eyes, or into any cuts or scratches.
- If the residue should get into your eyes,
flush them with water.

176 Airbag system
There are some important things you have to
know to make sure that the effectiveness of
the system will not be impaired and that dis
carded components do not cause injury or pol
lute the environment.
A WARNING
Improper care, servicing and repair proce
dures can increase the risk of personal in
jury and death by preventing an airbag
from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cu
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system .
- All work on the steering wheel, instru
ment panel, front seats or electrical sys
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc .) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace
ment upholstery over the front seat
backs that have not been specifically
approved by Audi . -
Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air
bag module must always be repaired
immediately by an authorized Audi
dealer .
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed,
it must be replaced with new replace
ment parts designed and approved espe
cially for your Audi model version. Re
placement of complete airbag systems
or airbag components must be per
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty
& Main
tenance booklet under
AIRBAG REPLACE
MENT RECORD .
-In accidents when an airbag is deployed,
the vehicle battery separates the alterna
tor and the starter from the vehicle elec
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre
cautions must be followed.
