190 Airbag sys tem
If the tota l weight on the front passenger
seat is more than that of a typical 1 year-o ld,
but less than the weight of a small adu lt, the
front airbag on the passenger side may deploy (the
PA SSEN GER AIR BAG OFF light does not
come on).
For e xample , the airbag m ay deploy if :
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld safety seats listed
¢ page 207),
-a chi ld 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.
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 adu lt o r teenager is o n the front pas
senger seat
- a passenger who is not sitt ing upright w ith
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 passenge r seat .
I f the front passenge r airbag deploys, the
F ederal Standa rd requires the airbag to meet
the " low ris k'' deployment criteria to help re
duce 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 electronic control un it.

Alway s remember : Even though yo ur 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 all of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag
inf lates, a lways wear safety belts prope rly. -
If you are unrestrained, leaning forward,
sitt ing s ideways or o ut of pos ition in any
way, your risk of injury is muc h higher.
- You will a lso receive serious injuries and
could even be killed if you are up aga inst
the airbag or too close to it when it in
f lates -even w it h an Advanced A irbag

A WARNING "---
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be serious ly inju red and ca n be killed if
the front airbag infla tes -even with an Ad
vanced A irbag System.
- Al tho ugh t he Advanced Airbag Sys tem in
your veh icle is designed to turn off the
front airbag when a rearward -facing
child restraint has been insta lled on the
front passenger seat, nobody can abso lutely g uarantee that dep loyment is im
possible in all conceivable situations that
may happen dur ing the usefu l life of your
veh icle.
- The inflating airbag will h it the ch ild
safety seat or i nfant carrier with great
force and will smash the child safety seat

A WARNING
-If, in except ional circumstances, you must
i nstall a forward-facing child restraint on
the front passenge r's seat:
II--
-Always make sure the forward-facing
seat has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag .
- Never put the forward-facing child re
straint up aga inst 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 insta lling
the fo rward-facing child restraint . The

Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brack
ets, and more . The function of the system in
the front passenger seat is checked by the
e lectronic control un it when the ignit ion is on .
The control un it mon itors the Advanced Air
bag Sys tem and turn s the a irbag in dica tor
light on when a ma lfunction 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 A irbag System, you must take care to
prevent it from being damaged . Damage to
the seat may p revent the Advanced A irbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag System
consists of the following:
- Crash sensors in the front of the veh icle that
measu re ve hicle accelera tion/decele ra ti on
to provide inform ation to the Advanced Air
bag System about the severity of the crash.
A irbag system 19 1
-An elect ron ic cont ro l unit, with integrated

-Improper repair or disassembly of the
front passenger and driver seat will pre
vent the Advanced Airbag 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
driver seat from the vehicle .
- 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-sensing mat and send the
wrong information to the airbag control
unit.
- Never store items under the front pas·
senger seat. Parts of the Advanced Air
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper
ly.
- Never place seat covers or replacement
upholstery that have not been specifical
ly approved by Audi 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 deploying prop
erly.
- 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
accurately registering the child restraint
or person on the seat and prevent the
Advanced Airbag System from function
ing properly.
- If you must use a child restraint on the
front passenger seat and the child re- straint manufacturer's instructions
re
quire 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 re·
straint is installed on the front passen
ger seat.
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immedi
ately install child restraint in a rear seat
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
side airbags supplement the protection of
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help reduce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the impor
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need Airbag System
and the activation of the safety belt preten
sioners depend on the deceleration measured
by the crash sensors and registered by the
electronic control unit. Crash severity depends
on speed and deceleration as well as the mass
and stiffness of the vehicle or object involved
in the crash .
When the electronic control unit registers a low severity crash and the safety belt is being
used, the airbag will not deploy. If the safety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat· er time in the crash sequence.
If the electronic control unit registers a crash
of medium severity, the first stage of the air ·
bag deploys followed by the second stage at a
much later time in the crash sequence· re·
gardless of whether the safety belt is being
used or not . In higher severity crashes as reg
istered by the electronic control unit, both the ..,.
first and second stages deploy almost at the
same time.
On the passenger side, regard less of safety
be lt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amo unt programmed in the electronic control
un it. The front airbag on the passenger side
w ill also be turned off if one of the child safe
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recog nized 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 t urned off

_&. WARNING
To reduce the risk of injury when an airbag
inf lates, a lways wear safety belts properly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, yo ur risk of inj ury is much higher.
- You w ill also receive serio us injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in
flates -even with an Advanced Airbag

More important things to know about
front airbags
F ig. 2 11 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfo ld properly and pro
vide supplemental protection in a fronta l col
l ision.
A irba g sy stem 193
The front airbags are designed to provide ad
ditional protection for the chest and face of
the driver and the front seat passenger when:
- safety belts are worn properly
- t he seats have bee n positioned so that the
occ upan t is properly seated as far as poss i
b le from the airbag
- and the head restraints have been properly
adj usted
Because airbags inflate in the blink of an eye
with great force, t hings you have on your lap
or have placed on the seat co uld become dan
gerous projecti les, and be p ushed in to you if
the a irbag inf lates.
When an airbag deploys, fine dust is re leased.
T his is no rma l and is not caused by a fi re in
the vehi cle. This dust is made up mos tly of a
powder used to lub ricate the airbags as they
deploy. It could irritate skin.
It is important to remembe r that wh ile the
s u pplementa l airbag system is designed to re
duce the like lihood o f serious injuries, other
injuries, for example swelling, bruising and
minor abrasions, can a lso happen when air
bags inflate . A irbags do not protect the arms
or the lower parts of the body. Front airbags
supplement the th ree-point safety belts only
i n some frontal co llisions in which the vehicle
deceleration is high enough to deploy the air
bags.
Front a irbags will not deploy :
-if the ignition is sw itched off when a crash
occurs
- in side collisions
- in rear-end co llisions
- in rollovers
- when the crash dece leration meas ured by
the air bag system is less than the minimum
threshold needed for airbag deployment as
reg istered by the electronic cont ro l unit
The front passenger airbag also will not
deploy:
- when the front passenger seat is not occu-
pied ..,.
194 Airbag sys te m
- when the weight on the front passenger
seat as sensed by the Advanced Airbag Sys
tem indicates that the front airbag on the
passenger side has to be turned off by the
electron ic control unit (the
PA SSEN GER AIR
BAG OFF
light comes on and stays on)
A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the r isk of injury when the air
bags inflate, the driver and passengers
must always sit in an upright position,
must not lean against o r place any pa rt
of the ir body too close to the area where
the airbags are located .
- Occ upants who are unbelted, out of posi
t ion 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 186.
A WARNING -
A child in a rearward-facing child safety
seat installed 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.
- The inflating a irbag will hit the child
safety seat or infant carrier with great
force and w ill smash the ch ild safety seat
and child against the backrest, center
armres t, door or roof.
- Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward-fac ing
child safety seat on the front passenger
seat because of excep tional circ umstan
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
i nc rease the r isk of injury in a crash by in
terfering with the way the airbag unfolds
or by be ing pushed into you as the airbag
i n flates.
- Never hold things in yo ur hands or on
your lap when the veh icle is in use.
- Never transpo rt items on or in the area
of the front passenger seat. Objects
could move into the a rea of the front air
b ags du ring bra king or other sudden ma
neuvers and become dangero us projec
tiles that can cause serious personal in
jury if the ai rbags inflate.
- Never p lace or attach accessories or oth
er objects (such as cupholde rs, tele
phone brackets, large, heavy or bulky ob
jects) on the doors, ove r or near the area
marked "AIRBAG" on the steer ing whee l,
instrument panel , seat backrests or be
tween those areas and yourself . These
objects could ca use in jury in a c rash, es
pecially when the airbags infla te.
- Never recline the front passenger 's seat
to transpo rt objects . Items can a lso
move into the a rea of the s ide airbag or
the front airb ag d uring bra king or in a
sudden maneuve r. Objects nea r the air
bags can become projectiles and cause
in ju ry, partic ularly when the seat is re
clined.
- Never tilt the front passenger seat back
rest forward when the vehicle is moving .
An inflating a irbag w ill force the back
rest backward and can injure rear seat oc
cupants.
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.

- Have the airbag system inspected imme
diately by your author ized Audi dealer .
A WARNING
If the front airbag inflates, a ch ild without
a child restraint, or in a rearward-fac ing
child safety seat, o r in a forward-facing
child restraint that has not been properly
installed will be serio usly injured and can
be killed.
- Even though your veh icle is equipped
with an Advanced Airbag System, make
certain that a ll children, especially 12
years and younge r, a lways ride on the
A irbag sys tem 197

Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi . Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working p roperly in a collision.
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 .
-For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech
nic circuit interrupter.
- Work on the pyrotechnic circuit inter
rupter must only be performed by a
qualified dealer - risk of an accident!
