restraints 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 add itional padd ing will prevent
the weight-sens ing mat in the seat from
accurately reg istering the ch ild restra int
or person on the seat and preve nt the
Advanced Airbag System from func tion­
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
quire the use of a towel, foam cush ion or
something else to properly position the
child restraint, make certa in that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re­
st ra int is installed on the front passen­
ger seat .
- If the
PA SSE NGER AIR BAG OFF light
does not come on and stay on, have the
airbag system inspected by your Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side airbags s upplement the protection of­
fered by the front three-point safety be lts
with pretensioners and load limiters and the
adjustab le head restra ints to he lp reduce the
risk of injury in a wide range of acc ident and
crash situat ions . Be sure to read the impor­
tant information about safety and heed the
WARNINGS in this chapter .
Deployment of the Advanced Airbag System
and the act ivat ion of the safety be lt preten­
sioners depend on the dece le rat ion measured
by the c rash sensors and registered by the
e lectronic control un it . Crash severity depends
on speed and dece leration as well as the mass
and stiffness of the vehicle or object involved in the crash .
Airbag system 119
When the electronic control unit registers a
low severity cras h and the safety belt is being
used, the airbag will not dep loy. If the safety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat­ er t ime in the crash sequence.
If the electron ic 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 be ing
used or not . In higher sever ity crashes as reg­
iste red by the elect roni c cont rol unit, bot h the
first and se cond s tages deploy almost at the
same t ime.
On the passenger side, regardless of safety
belt use, the airbag w ill be tu rned off if the
weight on the passenger sea t is less than the
amount programmed in the electronic 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
recognized on the seat. The
PASS ENGER A IR
BAG OFF light comes on and stays on to tell
you when the front Adva nced A irbag on the
passenger side has been turned off

_&. WARNING ~
To reduce the risk of inj ury when an a irbag
inflates, always wear safety be lts properly.
- If you are unrestrained, leaning forward,
sitting sideways or o ut o f position in any
way, your risk of injury is m uch higher.
- You will a lso receive serious injuries and
could even be killed if yo u are up against
the airbag or too close to it when it in­
f lates -even with an Advanced A irbag

More important things to know about
front airbags
F ig. 1 19 Inflated fro nt airbags
Safety belts are impo rtant to help keep fro nt
seat occupants in the p roper seated pos it io n
so that airbags can unfo ld prope rly and pro­
vide supplemental protection in a fronta l co l­
lision .
The front a irbags are designed to provide ad­
d itiona l protect ion for the chest a nd face of
the dr iver and the front seat passenger when:
- safety belts are worn properly,
- the seats have been positioned so that the
occupant is properly 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 or have placed on the seat could become dan­
gerous projectiles, and be pushed into you if
the airbag inflates .
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 cou ld irritate ski n.
It is important to remember that while the
supp lemental airbag system is designed to re­
duce the l ikelihood of serious inj uries, other
i n juries, fo r example swelling, bruisi ng and
m inor abrasions, ca n also happe n when air­
bags in flate. Airbags do not protect the a rms
or the lower pa rts of the body. Front airbags
only supplement the t hree point safety belts
in some frontal collisions in which the vehicle deceleration
is high eno ugh to deploy the air ­
bags .
Front airbags will not deploy:
- if the ignition is sw itched off when a c rash
occu rs,
- in side co llisions,
- in rear-end co llisions,
- in rollovers,
-when the crash deceleration measured by the airbag system is less than the min imum
threshold needed for a irbag deployment as
reg istered by the electronic control unit .
The front pass enge r airbag will al so not
deploy:
- when the front passenger seat is not occu­
p ied,
- when the weight on the front passenger
seat as sensed by the Advanced Airbag Sys ­
tem indicates that the front ai rbag on the
passenger side has to be turned off by the
elec troni c control un it (the
PASSENGER AIR
BAG OFF
li ght comes on and stays o n).
_&. WARNING ~
Si tting in the wrong position can increase
the r isk o f se rious injury i n crashes.
- To reduce the risk of inju ry w he n t he air ­
bags inflate, the drive r and passengers
m ust always sit in an upr ight position,
m ust not lean aga inst or place any part
of their b ody too close to the area where
the airbags a re located .
- Occupants who are unbelted, out of posi­
tion or too close to the a irbag can be se­
rio usly injured by a n airbag as it unfolds
wit h great force in the blink of an eye
<=:>page 112 .
_&. WARNING ~ -
A child in a rearward-fac ing c hild safety
seat installed on the front passenger seat
will be serio usly injured a nd ca n be killed if
the front air bag in fla tes -even with an Ad­
vanced A irbag Sys tem.

-The inflating airba g will hit the child
safety seat or infant carrier wit h great
f o rce and w ill smash t he ch ild safety seat
and child aga inst the backrest, cente r
arm rest, d oor or roof.
- Never install a r earward facing child
sa fety seat on the front pass eng er s eat
unless the
PASSENGER AIR BAG OFF
light c omes on and stays on. If the PAS­
S ENGER AIR BAG OFF
ligh t does no t
c o m e on and stay on, the inflating airbag
will hit the child safety seat or infant car­
rier with great force and will smash the
child safety seat and child against the
backrest, door or roof. Have the airbag
system inspected immediately by your
authorized Audi dealer .
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
your lap when the vehicle is in use .
- Never transport items on or in the area
of the front passenge r seat. Objects
cou ld move into the area of the front air­
bags dur ing braking or other s udden ma­
neuver and become dangerous projec ­
ti les 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 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 in to the area of the side airbag or
the front airbag dur ing braking or in a
sudden maneuver . Objects near the air -
-
Airbag system 12 1
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
ing cond itions.
- To reduce the risk of breath ing problems,
those with asthma o r other respiratory
conditions shou ld get fresh air r ight
away by getting o ut of the veh icle or
open ing windows or doors.
- If you are in a collision in which airbags
deploy, was h 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 cuts or sc ratches .
- If the resid ue should get into your eyes,
f lush them w ith wate r.
Monitoring the

on whenever the ignition is on .
A WARNING
An airbag system that is not funct ioning
properly cannot provide supplemental pro­
tection in a frontal crash.
- If the airbag indicator light comes on, it
means that there may be someth ing
wrong with the Advanced Airbag System .
It is possible that the airbag will inflate
when it is not supposed to, or w ill not in­
flate when it should.

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not functioning
p roperly cannot provide supplemental pro­
tection in a frontal c rash.
- If the airbag ind icator light comes on, it
means that there may b e something
wrong with the Advan ced Airbag Sys tem.
It is poss ible that the air bag w ill inflate
when it is not supposed to, or will not in ­
f late when it sho uld .
- Have the airbag system inspe cted imme­
diate ly by your 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 proper ly installed
will be ser ious 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

years and younger, a lways ride proper ly
restrained for their age and s ize.
- If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan­
ces and the
P ASS ENGER AIR BAG OFF
light does not appear and stay on have
the a irbag system inspected by your Audi
dealer.
-A tight tether or other strap on a rear­ ward-fac ing child restra int attached to
the front passenger seat can put too much pressure on the weight-sens ing
mat in the seat and register mo re weight
than is actually on the seat. The heavier
weight registered can make the system
work as though an ad ult were on the seat
and dep loy the Advanced Airbag when it
must be suppressed caus ing serious or
even fatal injury to the child.
- If, in exceptional circumstances, you
must install a forward-facing child re­
straint on the front passenger seat, a l­
ways move the seat into its rearmost po­
sit ion in the seat's fo re and aft adjust­
ment range, as far away from the airbag
as possib le. The backrest m ust be adjus t­
ed to an upr ight position. Make sure that
the
PASSENGER AIR BAG OFF light
comes on and stays on all the t ime when­
ever the ignition is switched on.
A WARNING
- If the PASSENGER AIR BAG OFF light
does not go out when an adult is sitting
on the front passenge r seat afte r taking
the steps described above, have the air­ bag system inspected by your Audi deal­
er before transpor ting anyone on the
front passenger se at.
(D Tips
If the weight-sensing mat in the front pas­
senger seat detects an empty seat, the
front airbag on the passenge r side will be
turned off, and
PASSENGER AIR BAG OFF
w ill stay on.

Repair, care and disposal of the airbags
Pa rts of the airbag system are i nstalled at
many diffe rent p laces o n your Aud i. Insta llin g,
removi ng, servicing or repa iring a part in an
area of the veh icle can damage a part of an
airbag system and prevent that system from
working properly in a coll is ion.
T he re a re some important t hings yo u have to
know to make sure that the effectiveness o f
t h e system wi ll not be impaired and that dis­
carded components do not cause injury or pol ­
l ute the environment.
A WARNING
Improper care, serv ic ing and repair proce­
du res can increase the risk of personal in­
j u ry and death by prevent ing an a irbag
from deploying when needed or dep loying
an a irbag une xpec tedly:
- Never cover, obst ruct, or change the
steer ing whee l horn pad or ai rbag cover
or the in st rument panel or mod ify them
in any way .
- Never attach any objects s uch as c up
holders or telephone mountings to the
sur faces covering the a irbag un its.
- For cle aning the horn pad or instr ument
panel, use only a soft, dry clo th or one
moistened with pla in water. Solvents o r
cleaners could damage the airbag cover
or change the st iffness or strength of the
material so that the airbag cannot de­
p loy and protect properly.
- Never repair, adjust, or change any parts
of the a irbag system.
- All work on the steering wheel, instru­
ment panel, front seats or e lectr ica l sys­
tem (including the installation of audio
equ ipment, cellu lar telep hones and CB
radios, etc.) must be performed by a
qualified technic ian who has the training
and specia l equipment ne cessary.
- For any wo rk on the airbag system, we
strongly recommend that you see your
author ized Audi dealer or qualified work-
shop. ..,.

-Never modify the 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
ment upho lstery ove r the front seat­
backs that have not been spec ifically
approved by Audi.
- Never use add itiona l seat cushions that
cover the areas where the side airbags
inflate .
- Damage to the o rigina l seat covers or
to the seam in the area of the side air­
bag module must always be repa ired
immediate ly by an authorized Audi
dealer.
- The airbag system can be activated only
once . After an airbag has inflated, it
must be replaced by an author ized Audi
dealer or qualif ied 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
c ially for your Aud i model version. Re­
placemen t of complete ai rbag systems
or airbag components m ust be per­
f ormed by qualified workshops only.
Make su re that any airbag service act ion
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- For safety reasons in severe accidents,
the a lternator and starter are separated
from the vehicle battery with a pyrotech­
nic circuit interrupter.
- Work on the pyrote chnic cir cu it inter­
rupter must on ly be per formed by a
qualified dealer - risk of an accident!
- If the veh icle or the ci rcuit interrupter
is sc rapped, all applicable safety pre ­
cautions must be followed .

Knee airbags
Description of knee airbags
T he knee airbag system can provide supple ­
mental protection to properly restrained
front seat occupants .
Fig. 121 Driv er 's airbag
The drive r knee airbag is in the instrument
panel underneath the steering whee l

about the same height in the instrument pan­
el underneath the glove compartment .
T he knee air bag offe rs addi tional p rotec tion
to the driver 's and passenger's knees lower
t h igh areas as a supplement to the protection
by the safety belts .
If the fron t airbags dep loy, the knee a irbags
also dep loy in frontal collisions w hen the de­
ployment threshold stored in the control unit
is met ~
page 120, More important things to
know about front airbags .
In addition to their normal sa fety function,
safety belts help keeping the driver or front
passenger in position in a fronta l co llision so
that the airbags can provide supp lemental
protection .
T he airbag system is not a substitute for your
safety belt . Rather, it is part o f the overa ll oc ­
cupant restra int system in your vehicle. A l­
ways remember tha t the a irbag system can
o nly he lp to protect you if you are wearing
you r safety belt and wea ring it properly . This
is why you should a lways wear your safety
belt, not jus t be cause the law requ ires you to
do so~
page 103 , General notes.
The safety belt buckle fo r th e driver and front
seat passenger have switch es that tell the air­
bag control module if the safety bel t is being
u sed or not .
If the sa fe ty belt is be ing used ,
t h e knee a irbag w ill deploy at a s light ly h igher
rate of dece leration than if the be lt is not be ­
ing used . Therefore, in a particular co llision, it
is possib le that an airbag will not dep loy at a
seating pos ition where the safety belt is being
used but will inflate at the posit ion where the
safety belt is not being used .
Remember too, airbags w ill deploy on ly once
and only in certa in kinds of acc idents - your
safety belts are always there to offer protec­
t io n in those accidents in which airbags are
not supposed to deploy o r whe n they have al­
ready dep loyed, for example when your vehi­
cl e s trikes or is st ru ck by ano ther after the
first collision . ..,.
