How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side airbags supplement the pro tection of­
fe red by the fro nt three -point safety be lts
with pretensioners and load limiters and the
adj ustab le head restra ints to he lp reduce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the impor­
tan t information about safety and heed the
WARNINGS in this chapter .
Deployment of the Advanced A irbag System
and the act ivation of the safety be lt preten­
sioners depend on the decelerat ion measured
by the crash sensors and registered by the
electronic control un it . The amount of infla ­
tion of the front airbags can also be adapted
to the front seat position, depending on the d istance between the respe ctive front seat
and the steering whee l or inst rument panel as
registered by sensors in the seats. Crash se­
verity depends on speed and deceleration as
well as the mass and stiffness of the vehicle
or object invo lved in the crash .
On the passenger s ide, regard less of safety
be lt use, the front passenger fronta l airbag
will be t urned off if the electrical capacitance
measured by the capacitive passenger detec­
tion system on the front passenge r seat is less
than the amount programmed in the electron­
ic control unit . The front passenger fronta l air ­
bag will a lso be turned off if the capac itance
measured by the system for the front passen­
ger seat eq ua ls tha t of an infant o f abo ut one
year of age in one o f the child seats that was
used to cert ify the Advanced Airbag System
under Fede ral Motor Vehicle Safety Standard

A WARNING
To reduce the risk of injury w hen an airbag
in flates, always wear safety be lts p ro perly.
- If you are unrestra ined, leaning forward,
sitt ing s ideways or out of pos ition in any
way, your ris k of injury is m uch higher.
- You will a lso receive serious injuries and
could even be killed if you are up aga inst
the airbag o r too close to it when it in­
flates -even w it h an Advanced A irbag

More important things to know about
front airbags
Fi g. 14 3 In flated front a irbags
Safety belts are important to help keep front
seat occupants in the proper seated position
so that ai rbags can unfold p roper ly and pro­
v ide s upplementa l pro tect ion in a fron tal col­
lis ion .
T he front airbags a re des igned to provide ad­
di tional protection fo r the chest and fa ce of
the d river a nd 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 poss i­
b le from the airbag ,
- and the head restraints have been properly adjusted .
Because airbags inflate in the bli nk of an eye
wi th great force, things you have on your lap
or have placed on the seat cou ld become dan ­
gerous p rojecti les, and be pushed in to you if
t h e a irbag inf lates.
When an airbag deploys, fine dust is re leased.
This is norma l and is not caused by a fire in .,,.

the vehicle. This dust is made up most ly o f a
powder used to lubricate the airbags as they
deploy . It cou ld irritate sk in .
I t is important to remember that whi le the
supp lemental airbag system is designed to re ­
duce the likelihood of serious injuries, other
in ju ries, for example swelling, bruising and
minor abrasions, can also happen when air­
bags inflate. Airbags do not protect the arms
or the lower parts of the body . Front airbags
supplement the three-poi nt safety belts only
in some frontal co llisions in which the vehicle
dece le ra ti on is high enough to deploy the air­
bags.
Front airbags will not deploy:
- if the ignit io n is switched off when a crash
occurs,
- 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
threshold needed for airbag deployment as
registered by the e lectronic control unit.
Th e front pa ssenger airbag al so will not
d epl oy:
- when the front passenger seat is not occu ­
pied,
- when the electrical capacitance measured by
the capacitive passenger detection system
for the front passenger seat indicates that
the passenger side frontal airbag must be
switched off by the electron ic control unit
(the
PASSENGER AIR BAG OFF light
<> page 150 and how they wo rk comes on
and stays on).
.&_ WARNING
Sitting in the wrong posi tion can inc rease
the risk of serious injury in crashes .
- To reduce the r is k of i njury when the air­
bags inflate, the driver and passengers
must always sit in an upright position,
must not lean against or place any part of their body too close to the area whe
re
the airbags a re located .
- Occupants who are unbelted, out of posi­
tion or too close to the airbag can be se­
rio us ly injured by an airbag as it unfolds
with great force in the blink of an eye
<> page 139 .
.&_ WARNING
--A child in a rearward-fac ing ch ild seat in -
stalled on the front passenger seat wi ll be
se riously in ju red and can be killed if t he
front ai rbag inflates - even w ith an Ad­
vanced A irbag System.
- The inflating airbag will h it the c hild seat
or infan t ca rrier with grea t for ce and will
smash the child sea t and chi ld against
the backrest, center armrest, door or
roof.
- Always install rear -fac ing ch ild seats on
the rear seat.
- If you m ust ins ta ll a rearw ard fac ing
chi ld seat on the front passenger seat
because of exceptional circumstances
and the PASSENGER AIR BAG OFF light
does not come on and stay on, immed i­
ately insta ll the rear-facing child seat in a
rear seat ing pos ition and have the airbag
system inspected by you r Audi dealer .
.&_ WARNING
= -
Objects between you and the airbag will
i nc rease the r is k of injury in a crash by in­
terfer ing with the way the a irbag unfolds
or by be ing p ushed in to you as the airbag
i nflates.
- Neve r hold things in yo ur hands or on
your lap when the veh icle is in use.
- Never transpo rt items on o r in t he a rea
of the front p assenger sea t. Objects
could move into the a rea of the front a ir­
bags du ring braking or other sudden ma ­
neuvers and become dangero us projec­
tiles that can cause ser ious personal in-
jury if the a irbags inf late. ..,.

-Never place or attach accessories or o th ­
er objects (such as cup hol ders, 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 a reas and yourself. These
objects co uld cause injury in a crash, es­
pecially when the airbags inflate .
- Never recline the front passe nger's seat
to transport objec ts. Items can also
move into the area o f the side airbag or
the front airbag during braking or in a
sudden maneuver . Objects near the air­
bags can become project iles and cause
injury, part icularly when the seat is re­
cl ined .
- Never place or transport ob jects on the
front passenger seat. Objects on the
front passenger seat could cause the ca­ pacitive senso r in the seat to s ignal to
airbag system that the seat is occupied
by a person when it in fa ct is not, o r that
the person on the se at is he avier than he
or she actually is. The change in electric
capacitance beca use of such objects can
cause the passenger front airbag to be
turned on when it sho uld be
off, or can
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout objects on the seat.
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenge r detection
system in the s eat to s ignal to the A irbag
System that the seat is oc cupied by a
pers on when it is not, or to sign al th at it
is occupied by someone who is heavier
than the pe rson actually s itting on the
seat . The presence of an object co uld
cause the passenger front a irbag to be
turned on when it sho uld be
off, or co uld
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout the object on the seat. A

Repair, care and disposal of the airbags
Parts of the a irbag system are installed at
many different places on your Audi. Installing,
removing, servic ing or repairing a part in an
area of the vehicle can damage a part o f an
airbag system and prevent that system from
working properly in a co llision.
There are some important things you have to know to make sure that the effect iveness of
the system will not be impaired and tha t dis ­
carded components do not cause injury or po l­
l ute the env ironment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag
from deploy ing when needed o r deploying
an airbag unexpected ly:
- Never cover, obstruct, o r change the
steering wheel ho rn pad or airbag cover
o r th e instrument pane l or modify them
in any way.
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the ho rn pad or instrumen t
pane l, use only a soft, d ry cloth or one
mois tened w ith plain wate r. Solven ts or
cleaners co uld damage the airbag cover
or change the stiffness o r strength of the
A irbag sys tem 153
material so that the airbag cannot de­
ploy 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 telephones and CB
radios, etc.) must be performed by a
qualified technic ian who has the training
and specia l equipment necessary.
- For any work on the airbag system, we strongly recommend that yo u see your
author ized Audi dealer or qualif ied work­
shop.
- Never modify the front bumper or pa rts
of the vehicle body.
- Always make sure that the s ide a irbag
can inflate without inte rfe rence:
- Never in.stall seat covers or rep lace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat c ushions that
cover the areas where the side a irbags
i nflate.
- Damage to the orig inal seat cove rs or
to the seam in the area of the side a ir­
bag module must a lways be repaired
i mmediately by an author ized Audi
dealer.
- The airbag system can deploy on ly once.
After an a irbag has been deployed, it
m ust be replaced with new replacement
pa rts des igned and app roved espec ially
for your Aud i mo del ve rsion. Replace­
men t of comple te airbag systems or air­
bag components must be performed by
qualified workshops only . Make sure that
any airbag service action is entered in
your Audi Warranty

ways remember that the airbag system can
only help to protect you if you are wea ring
your safety belt and wear ing it prope rly . T hi s
i s why you shou ld always wear you r safety
be lt, not just because the law requires yo u to
do soc>
page 128, General notes.
The safety belt buck le for the dr iver and front
seat passenge r have switc hes that tell the a ir­
bag con trol mod ule if the safety belt is be ing
used or not . If the safety belt is being used,
the knee airbag will deploy at a slightly higher rate of deceleration than if the belt is not be ­
ing used. Therefore, in a particu lar collision, it
is poss ible that an airbag will not deploy at a
seating position where the safety belt is being
used but will inflate at the position whe re the
safety belt is not be ing used.
Remember too, airbags will deploy only once
and only in certain kinds of accidents -your
safety belts are always there to offer protec ­
tion in those acc idents in which a irbags a re
not supposed to deploy or when they have a l­
r eady deployed, fo r example whe n your veh i­
cle strikes or is s truck by another afte r the
fi rst coll is ion .
This is just one of the reasons why an a irbag is
n ot a substi tute fo r the safety belt. The airbag
sys tem works most effective ly when used with
A irbag system 15 5
the safety belts. Therefore, always wear yo ur
safety belts correct ly .
I t i s important to remembe r that w hile the
s u pplementa l knee airbag system is designed
to reduce the likelihood of ser ious injuries,
other injuries, for example, swelling, bruising,
minor abrasions and friction b urns can a lso
occur when an airbag inflates.
The knee airbag system basically consists
of:
- The e lectronic control module
- Two inflatable ai rbags (airbag and gas gen -
erator), one for the driver and one for the
front passenger
- The ai rbag indicator lig ht in the i nstrument
pane l
The knee airbag system will not deploy:
-when the ignit io n is switched off
- in frontal collisions when the deceleration
measu red by t he con trol un it is too low
- in side co llisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warn-
ing/ind icator light is on)
c> page 17.
A WARNING
- Safety belts and the airbag system can
only provide protection when occupants
are in the proper seating position
i=>page 147.
- If the airbag ind icator light comes when
the vehicle is be ing used, have the sys­
tem inspected immediate ly by you r au­
thori zed A udi dealer. The airbag may not
wo rk properly when the vehicle acce le ra­
tion in a side co llision is high enough to
deploy the airbag . See also

158 Airbag system
A lways remember that the side airbag system
can only help to protect you if you are wearing
your safety belt and wear ing it properly. This
is another reason w hy you should always wear
your safety belts, not just because the law re­
qu ires you to do so
Q page 128, General
notes.
It is important to remember that while the
supplemental side a irbag system is designed
to reduce the likelihood of serious injur ies,
other inju ries, fo r example, swell ing, b ruising,
frictio n burns and mi nor abrasions can also be
associa ted with deployed side airbags. Re ­
member too, side air bags will deploy only
once and only in certain k inds of accidents -
your safety be lts are always there to offer pro­
tection .
Vehicle damage, repa ir costs or even the lack
of vehicle damage are not necessar ily an indi­
cation of over-sensitive or failed airbag activa­
tion. In some co llisions, both front and side
a irbags may inflate. Remember too, that air­
bags will dep loy only once and only in certain
kinds of collisions -your safety belts are al­
ways there to offer protection in those acci ­
dents in wh ic h air bags are not supposed to
deploy or when they have already deployed.
The side airbag syst em will not deploy:
- when the ign ition is switched off
- in s ide collisions when the acceleration
measured by the sensor is too low
- in front-end col lisions
- in rear -end collisions
- in ro llovers.
In some types of acc idents the front airbags,
side curta in a irbags and side airbags may be
tr iggered together.
.&_ WARNING
- Sa fety belts and t he ai rbag sys tem w ill
only prov ide p rotec tion when occ upants
are in t he proper seating posit ion
Qpage 159.
- If the airbag indicator light comes on
when the vehicle is being used, have the
-
system inspected immediately by your
author ized Audi dealer. The airbag may
not work proper ly when the vehicle ac­
celeration in a side coll is ion is high
enough to activate the a irbag.
How supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained .

When the system is triggered, the airbag is
filled with propellant gas and breaks through
a seam in the seat su rface area marked "AIR­
BAG". It expands between the side trim panel
and the passenger. In order to help provide
t hi s addit ional protect ion, the side airbag
mus t inflate with in a fra ction of a second a t
very h igh speed and with great force. The sup­
pleme nta l side airbag could injure you if your
seat ing position is not proper or up right or if
items are located in the area where the sup­
plementa l side airbag expands. This applies
especially to children

Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduc e the risk of inju ry to the upp er

Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide
supplemental protection to properly restrain ­
ed occupants.
Fi g. 14 9 Side curtain airbags, dri ver 's side: s ide curta in
a ir bag location
The s ide curtain airbags are located on both
sides of the interior above the front and rear
side windows ~
fig. 149. They are ident ified
by the word "AIRBAG" on the windshield
frame and the center roof p illar.
The s ide curtain airbag system supplements
the safety belts and can help to reduce the risk of injury for occupants' heads and upper
torso o n the side of the vehicle tha t is struc k in
a side collision . The side curtain airbag in­
flates in side impacts and only when the vehi­
cle acceleration registered by the control unit
is high enough . If this rate is below the refer­
ence value programmed into the control unit,
the side airbags will not be triggered, even
t h ough the car may be bad ly damaged as a re­
su lt of the co llision .
It is not possib le to de­
fine an airbag triggering range that will cover every possib le ang le of impact, s ince the cir­
cumstances will vary cons iderably between
one collision and another. Important factors
include, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc.~
page 161 , How side cur­
tain airbags work .
Aside from their normal safety function, safe­
ty be lts work to help keep the driver or front
passenger in position in the event of a colli­
sion so that the side curtain airbags can pro­
vide protection .
The airbag system is not a substit ute for your
safety belt. Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the a irbag system can
only help to protect you if you are wear ing
you r saf ety belt and wearing it properly . This
is anothe r reason why yo u should always wear
yo ur safe ty belts, no t just because the law re ­
quires yo u to do so
q page 128, General
notes .
It is important to remember that w hile the
s ide cur tain airbag system is designed to help
reduce the likelihood of ser ious injur ies, other
injuries, for example, swelling, bruising, fric­
tion burns and minor abrasions can also be as­
sociated with these airbags upon dep loyment.
Remember too, these airbags will deploy only
once and only in certain kinds of accidents -
your safety belts are always there to offer pro ­
tection.
