Airbag System for the front passenger seat from
doing its job in a crash.
The front Ad vanced Airbag System con sists
o f the follo wing :
-Cras h sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System a bout the severity of the crash.
- An electronic control unit, with integrated
crash sensors for front and side impacts. The
contro l unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors . The control unit also "de­
c ides" whether the safety belt pretens ione rs
shou ld be activated .
-An Advanced Airbag with gas generator and
contro l valve for the d river ins ide the steer ing
whee l hub.
-An Advanced Airbag with gas generator and
contro l valve inside the instrument pane l for
the fron t passenger.
-A capac itive passenger detect ion system under­
neath the front passenger seat cover. This sys­
tem measures the elect ric al capac ita nce of the
person in the seat. The informat ion registe red
is sent contin uous ly to the e lectron ic control
unit to regulate deployment of the front Ad ­
vanced Airbag on the passenger side.
-An airbag monitoring system and indicator
light
m in the instrument cluster.
-A sensor in eac h front seat registers the dis ­
tance between the respective seat and the
stee ring wheel or instrument pane l. The infor ­
mation reg istered is sent continuously to the
electronic control unit to regulate deployment
of the front Adv a need A irbags .
-The PASS EN GER AIR BAG OFF ~; ON@ light
comes on in the headliner
c:> page 281,
fig. 236 and tells you the status of the Ad ­
vanced Airbag o n the passenge r side .
-A sensor i n the safety belt latch for the driver
and for the front seat passenger that senses
whethe r that safety belt is latched or not and
t ransm its this info rmat io n to the elect ronic
c ontro l unit.
Airbag syste m
A WARNING ~ -
Damage to the front passenger seat can pre­
vent the front airbag from working properly.
-Improper repair or disassembly of the front
passenger and driver seat will p revent the
Advanced A irbag System from f unct ion ing
p roperly.
-Repa irs to the front passenger seat must be
pe rformed by qualified a nd p roperly tra ined
wo rkshop personne l.
-Never remove the front passenger or driver
seat from the vehicle .
-Never remove the upholstery from the front
passenger sea t.
-Never d isassemble or remove parts from the
seat o r disconnect w ires from it .
-Never carry sharp objects in your pockets or
put them on the seat . The capacit ive pas­
senger de tec tion mat in the front passenger
seat will not funct ion p roperly if i t is punc­
tured.
-Never carry things on your lap or carry ob­
jects on the front passenge r seat. S uch ob­
jects ca n infl uence the capaci tance reg is­
t ered by the cap aci tive passenge r detection
sys tem, so that incorrect in forma tion is pro ­
vided to the ai rbag control unit.
-N eve r store i tems unde r the front p assenger
seat . Parts of the Advanced Airbag System
under the passenger seat cou ld be dam ­
aged, p reventing them and the airbag sys ­
tem from wor king p roper ly.
-Never p lace seat covers or replacement up ­
holstery that have not been specifically ap­
proved by Audi on the front seats.
-Seat covers can prevent the Advanced Air ­
bag System from recognizing chi ld re­
stra ints or occupants on the front passenger
seat and preven t the side airbag in the seat
backrest from deploy ing properly.
-If a seat heater has bee n retrofitted or oth­
erwise added to the front passe nger seat,
neve r ins tall any child restra int system on
t his seat.
-Never use cushions, p illows , blankets, or
sim ila r it ems o n the front passenge r seat .

Airbag syste m
The additiona l layers prevent the capacitive
passenger detection system from accurately
measuring the capac itance of the ch ild safe­
ty seat and/or the person on the seat and
thus keep the Advanced Airbag System from
working p roperly .
- Never place or use any electrical device (such as a laptop, CD player, elect ronic
games dev ice, power inverte r or seat heater
for child seats) on the front passenger seat if the device is connected to the 12-vol t
socket or the cigarette lighter socket . S u ch
devices can infl uence the capacitance regis­
tered by the capacitive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
- If you must use a child restraint on the front
passenger seat and the child restraint man­
ufacturer's instructions require the use of a
towel, foam cushion or something else to properly position the ch ild restraint, make
certain that the
PASSENGER AIR BAG OFF
~; light comes on and stays on whenever
the chi ld restraint is installed on the front
passenger seat .
-If the PASSENGER AIR BAG OFF ~; light
does not come on and s tay on, immedi ate ly
install child restra int in a rear seating posi ­
tion and have the airbag system inspected by your A udi dealer .
,&_ WARNING
If the front passenger seat gets wet, dry it im­
mediately.
- If liquid soaks into the front passenger seat,
this can keep the a irbag system from work­
ing prope rly and may, for instance, deact i­
vate the passenger frontal airbag. If this happens, the
PASSENGER AIR BAG OFF ~;
light will come on and stay on togethe r wi th
the a irbag ind icator light
m in the inst ru­
ment cluster.
- If liquid is poo led on the seat, bu t has not
soa ked in, this may also keep the airbag sys­
tem from wo rking properly and ca use the
passenge r frontal a irb ag to be enabled
(tu rned on), even though there is a properly
278
installed child restraint system on the seat .
Wet towels or other wet things on the seat
cushion can have the same effect. If the
front passenger fronta l airbag is turned on,
the
PASSENGER AIR BAG OFF ~; light will
turn off.
How the Advanced Airbag System
components work together
The front Advanced A irbag System and the side
airbags supp lement the protection offered by the
front t hree-point safety belts and the adjustable
head restraints to he lp reduce the risk of injury in
a wide range of accident and crash situat ions. Be
sure to read the important i nformat ion about
safety and heed the WARNINGS in this chapter .
Deployment of the Advanced A irbag System and
the activation of the safety belt pretensioners de­
pend on the dece leration measured by the crash
sensors and registered by the electronic contro l
u nit . Crash seve rity depe nds on speed and decel­
eration as well as the mass and stiffness of the
vehicle or object involved in the cras h.
On the passenger side, regard less of safety be lt
use, the front passenge r frontal a irbag will be
turned off if t he e lectr ica l capacitance measured
by the capacitive passenge r detection system o n
t h e fron t pa ssenger sea t is less th an the amou nt
prog rammed in t he e lec tronic contro l unit. The
front passenger frontal airbag wi ll also be turned
off if the capacitance measured by the system for
the front passenger seat equals that of an infant
of about one year of age in one of the chi ld seats
that was used to certify the Advanced Airbag Sys­
tem under Federal Motor Vehicle Safety Standard
208 . The
PASSENGER AIR BAG OFF ~; light
comes on a nd stays on to tell you when the front
Advanced Airbag System on the passenge r side
has been tu rned off<=?
page 281.
,&_ WARNING
T o reduce the ris k of injury when an airbag in ­
flates, always wear safety belts prope rly.
- If you are unres trained, leaning forward, si t­
ting sideways or out of position in any way,
your r isk of injury is much highe r.
~

Airbag syste m
airbag inflates -even with an Advanced 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-fac ing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF ~; light does not
come on and stay on, immed iate ly install
the rear-fac ing ch ild safety seat in a rear
seat ing pos ition and have the airbag system
inspected by your a uthorized Audi dea ler.
A WARNING
Objects between you and the a irbag w ill in ­
crease the risk of inj ury in a crash by interfer­
ing with the way the airbag unfo lds or by be­
ing pushed into you as the a irbag 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 airbags dur­
ing brak ing or other sudden maneuvers and
become dangerous projectiles that can
cause serious personal injury if the a irbags
inflate .
- Never place or attach accessor ies or other
objects (such as cupholders, telephone
brackets, large, heavy o r bulky objects) on
the doors, over or nea r the area marked
"AIRBAG" on the steering wheel, instru­
ment pane l, sea t backrests or between
those areas and yoursel f. These objects
could cause injury in a crash, especially
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 o r the front a ir­
bag dur ing braking or in a sudden maneu­
ver. Objects near the airbags can become
280
-
pro jecti les and cause injury, part icularly
when the seat is reclined.
- Never p lace or transport objects on the
front passenger seat. Objects on the front passenger seat could cause the capacitive
sensor in the seat to signal to airbag system
that the seat is occupied by a person when it
in fact is not, or that the pe rson on the seat
is heavie r than he or she act ually is . The
change in elec tric capa citan ce beca use of
such o bje cts can c ause the p assenge r front
airbag to be turned on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
wo rked without objects on the seat.
- Always make sure that there is nothing on
the front passenge r seat that will cause the
capacitive passenge r detection system in
the seat to signal to the Airbag System that
the seat is occup ied by a person when it is
not , or to signal that it is occupied by some­
one who is heavier than the person act ually
sitt ing on the seat. The presence of an ob­
ject could ca use the passenger front air bag
to be turned on when it should be off, or
could cause the airbag to work in a way that is different from the way it would have
worked without the object on the seat.
A WARNING
The fine dust created when airbags deploy can
cause breathing prob lems for people with a
h istory of asthma or other breath ing cond i­
tions .
- To reduce the r isk of breathing p roblems,
those with asthma or other respiratory con­
ditions should get fresh a ir right away by
getting out of the vehicle or opening win­
dows or doors .
- If you are in a collision in which airbags de­
ploy, wash your hands and face with m ild
soap and water before eating.
- Be ca refu l not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue should get into your eyes,
flush them w ith wate r.

interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
technicians who have the experience, in ­
formation and special tools necessary to
perform the work safely.
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed .
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified 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 modules and
safety belts with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend 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 example, using tire-rim
combinations not approved by Audi, lowering the
veh icle, chang ing 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 contro l 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 which it would not deploy if
the changes had not been made. Other kinds of changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
ing when it should .
Airbag system
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 on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Side airbags
· Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 237 Side a irbag locatio n in the driver's seat
The side airbags are located in the sides of the
front seat backrests
¢ fig . 23 7 and the rear back­
rest* facing the doors.
The side airbags installed for the front seating
pos itions have been des igned and certified to
help reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant s itting next to it is not seated prop­
erly. The side airbag for the front passenger seat
can be used w ith proper ly installed chi ld re­
straints . Please be sure to read the important in­
formation and warnings whenever using a child
restraint in a vehicle: Safety belts¢
page 261,
Airbag system ¢ page 269, Child safety
r:=> page 291.
The side airbag system basically consists of:
.,..
285

Airbag system
-the e lectronic control module and externa l side
impact sensors
- th e two side airbags located in the sides of the
front backrests
- two rear side airbags*
- the air bag wa rn in g light in the instrument clus-
te r.
The a irbag system is monitored electronically to
make certa in that it is functioning properly at all
times. Each time you turn on the ignition, the air­
bag system ind icator light will come on for a few
seconds (self diagnostics).
The s ide a irbag system supplements the safety
be lts and can help to reduce the risk of injury to
the driver's, front and rear* passenger's upper
torso on the side of the vehicle that is struck in a
side co llision . The airbag dep loys on ly in side im­
pacts and on ly when the vehicle acceleration reg ­
istered by the control unit is high enough. If this
rate is below the reference value programmed in­
to the control un it, the side airbags w ill not be
tr iggered, even though the car may be badly
damaged as a result of the collision. It is not pos­
sib le to define an ai rbag tr igger ing range that
w ill cover every possible angle of impact, s ince
t he circumstances will vary considerably between
one collision and another. Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc.
c> page 287, Important safety in­
structions on the side airbag system.
Aside from their normal safety function, safety
be lts work to help keep the driver or front pas ­
senger in position in the event of a side collision
so that the side a irbags can provide protection.
The airbag system is
not a substitute for your
safety belt . Rather, it is part of the overa ll occu ­
pant restraint system in your vehicle. Always re­
member that the s ide airbag system can only
help to protect you if you are wearing your safety
belt and wearing it properly. This is another rea­
son why you should always wear you r safety
be lts, not just because the law requ ires you to do
soc> page 261, General information.
It is important to remember that while the sup­
plemental s ide a irbag system is designed to re-
286
duce the likelihood of serious injuries, other inju­
ries, for example, swelling, bruising, friction
burns and m inor abras ions can also be assoc iated
with deployed side airbags. Remember too, side
airbags will dep loy only once and only in certa in
kinds of accidents
-your safety belts are always
there to offer protection .
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessar ily an ind ication
of over-sens itive or fa iled airbag activat ion . In
some collis ions, both front and side airbags may
i nflate. Remember too, that air bags w ill dep loy
only once and only in certain kinds of collisions
-
your safety belts are always there to offer protec­
tion in those accidents in which airbags are not
supposed to deploy or when they have alr eady
deployed.
The side airbag system will not deploy:
-when the ignition is turned off
- in side co llisions whe n the accele ration meas-
ured by the sensor is too low
- in fro nt-end coll is ions
- in rear-end collisions
- in rollovers.
In some types of accidents t he front airbags, side
curtain airbags and side airbags may be triggered
together.
A WARNING
- Safety belts and the airbag system will only
provide protection when occupants are in
the proper seat ing position
c> page 287.
-If the airbag ind icator light c> page 26
comes when the vehicle is being used, have
the system inspected immediately by your
author ized Audi dealer . It is possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.

Airb ag syste m
by being pushed into you as the airbag in­
flates.
- Never p lace or attach accessories or other
objects (such as cupho lders, telephone
brackets, or even large, bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the seat backrests.
- Such objects and accessories can become
dangerous projectiles and cause injury
when the supplemental side airbag de­ ploys.
- Never carry any objects or pets in the de­ ployment space between them and the
airbags or allow children or other passen­
gers to travel in this position.
- Always use the built-in coat hooks* only for
lightweight clothing . Never leave any heavy
or sharp-edged objects in the pockets that
may interfere w ith side airbag deployment
and can cause personal injury in an accident.
- Always prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks.
- The airbag system can only be triggered
once . If the airbag has been triggered, the
system must be replaced by an author ized
Audi dealership .
- Damage (cracks, deep scratches etc .) to the
original seat covers or to the seam in the
area of the side a irbag mod ule m ust always
be repa ired immed iate ly by an authorized
Audi dealer .
-If children are seated imp roperly, their risk
of injury increases in the case of an acc ident

- Never attempt to modify any components of
the a irbag system in any way.
- In a side collision, side a irbags w il l not func­
t ion properly if sensors cannot correct ly
measure increasing air pressure ins ide the
doors when air escapes through larger, un­
closed openings in the door panel.
- Never drive with inter ior door tr im panels
removed .
- Never drive when parts have been re ­
moved from the inside door panel and the
open ings they leave have not been proper­
ly closed.

- Never drive when loudspeakers in the
doors have been removed unless the
speaker holes have been properly closed.
- Always make certain that openings are
covered or filled if additional speakers or
other equipment is installed in the inside
door panels.
- Always have work on the doors done by an
authorized Aud i dea ler or qualified work­
shop.
Side curtain airbags
Description of side curtain airbags
The side curtain airbags can provide supplemen­
tal protection to properly restrained occupants.
Fig. 239 S id e curt ain air bags, driver's side : loc atio n
The side curtain airbags are located on both sides
of the inter ior
above the front and rear side win­
dows
¢ fig . 239 .
The side curtain airbags contain features that
provide ejection mitigation to help prevent vehi­
cle occupants or parts of the ir bodies from being
completely or part ially ejected from the vehicle
i nterior i n certa in side impacts and veh icle roll­
overs .
The side curtain airbag system supplements the
safety belts and can help to reduce the risk of in­
jury for occupants' heads and upper torso in a
s ide collision . The side curtain airbag inflates in
s ide impacts and on ly when the veh icle accelera­
tion registered by the control unit is high enough. If this rate is be low the reference va lue
programmed into the contro l unit, the side cur ­
tain airbag will not be triggered, even though the car may be badly damaged as a result of the
..,.

collision. It is not possible to define an airbag
triggering range that will cover every possible an­
g le of impact, s ince the circumstances will vary
considerably between one collision and another.
Important factors include, for example, the na­
ture (hard or soft) of the impacting object, the
angle of impact, vehicle speed, etc.

How side curtain airbags work .
Aside from their normal safety function, safety
be lts work to he lp keep the driver or front pas­
senger in pos it ion in the event of a collision so
that the side curtain airbags can p rovide protec­
tion .
The airbag system is not a substitute for your
safety belt . Rat he r, it is part of the overa ll occu­
pant restraint system in your veh icle . Always re­
member that the airbag system can only help to
p rotect yo u if you are wea ring your safety bel t
and wearing it properly . T his is another reason
why you should always wear your safety belts, not j ust because the law requires you to do so

It is important to remember that whi le the s ide
curtain ai rbag system is designed to he lp reduce
the likelihood of serious injuries, other inj uries,
for example, swelling, bruising, friction burns and minor abrasions can also be associated with
these airbags upon deployment . Remember too,
these airbags will deploy only once and only in
certa in ki nds of acc idents
-you r safety belts are
always there to offer protection .
The side curtain airbag sy stem basically
consists of:
- The electronic contro l modu le and external s ide
impact senso rs
- The side curtain airbags above the w indows of
the outer seating positions with ejection miti­
gation feat ures
- The airbag ind icator light in the instrument
panel
The airbag system is monitored electronically to make certain it is funct ion ing properly at all
u times. Each time you turn on the ignit ion, the air-co
~ bag system ind icator light will come on for a few r--
~ seconds (self d iagnost ics) .

The side curtain airbag is not activ ated :
-if the ignition is turned off
- in side co llisions whe n the acceleration meas-
ured by the sensor is too low
- in rear-end col lisions .

comes when the veh icle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possib le that
the airbag will inflate when it is not sup­
posed to, or will not inf late when it should.
How side curtain airbags work
Side curtain airbags con work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who are properly re­
strained.

When the system is triggered, the side curtain
airbag is filled with propellant gas and breaks
through a seam above the front and rear side
windows identified by the AIRBAG label. In order
to help provide this additional protect io n, the
