A WARNING
A child in a rearward-facing child seat instal­
led on the front passenger seat wi ll be seri­
ously injured and can be killed if the front air­
bag inflates -even with an Advanced Airbag
System.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the front
airbag when a rearward-facing child re­
straint has been installed on the front pas­
senger seat, nobody can absolutely guaran­
tee that deployment is impossible in all con­
ceivable s ituations that may happen dur ing
the usef ul life o f you r vehicle.
- The inf lating a irbag w ill hit the child seat or
infa nt carrier w ith great force and w il l
smash the ch ild seat and child agains t the
backrest, center armrest, door, or roo f.
- Always insta ll rearward -facing child re­
straints on the rear sea t.
-If you mus t install a rearward facing chi ld
seat on the fron t passenger sea t beca use of
exceptional circ umstances and the
PASSEN­
GER AIR BAG OFF light does not come on
and stay on, immediately install the rear ­
facing child seat in a rear seating position
and have the a irbag system inspected by
your Audi dealer.
A WARNING
If, in exceptional c ircumstances, you must in­
stall a forward-facing chi ld restraint on the
front passenger 's seat:
-Always make sure the forward-fac ing seat
has been designed and ce rtified by its man­
ufact urer for use on a front seat wit h a pas­
senger front and side airbag.
- Never put the forwa rd-facing child rest raint
up against or ve ry nea r the instrument pan­
el.
- Always move the passenger seat into its
rearmost position in the se at's fore and aft
adjustment range, as far away from the air­
bag as possib le, before installing the fo r­
war d-fac ing c hild restraint . The backrest
must be adjuste d to an up right position .

-
-Always ma ke sure that there is nothing on
the front passenger seat that w ill cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occup ied by a person when i t is
not, or to s ignal that it is occupied by some­
one who is heavier than the person a ctua lly
si tti ng on the se at. T he presence of addi­
tional objects could cause the p assenger
front airbag to be turned on when it s hou ld
be off, or co uld cause the a irbag to wo rk in a
way that is different from the way it would
have worked without the object on the seat.
- Make sure that the
PASSENGER AIR BAG
OF F light comes on and stays on all the time
whenever the ignit ion is switched on.
Advanced Airbag System components
The front passenger seat in your vehicle has a lot
of very impo rtant parts of the Advanced A irbag
System i n it. T hese pa rts include the capacitive
passenger detection system, wir ing, b ra ckets,
and more. The control u nit mon itors the system
o n the fron t passenger seat when the ign it ion is
swi tched on and turns the airbag indica tor ligh t
o n when a malfunction in the one of the system
components is detected~
page 155. Because
the front passenger seat contains important
parts of the Adv a need A irbag System, you must
take care to prevent it from being damaged .
Damage to the seat may prevent the Advanced
A irbag System for the front passenger seat from
do ing its job in a crash.
The front Advanced Airbag Sy stem consists
of the following:
- Cras h sensors in the front of the vehicle that
measu re vehicle acceleration/deceleration to
provide i nfo rmat ion to the Advanced Airbag
System abo ut the sever ity of the cr ash.
- An ele ct ro nic contro l unit, with integrated
crash sensor s for front and s ide impac ts. The
cont ro l uni t "dec ides" whether to fire the fron t
airbags based on the information received from
the crash se nsors . The control unit a lso "de ­
cides" whether the sa fety belt pretensioners
should be activated. ..,_

-An Advanced Airbag with gas generator and
control valve for the driver inside the steering
wheel hub.
- An Advanced Airbag with gas generator and
control valve inside the instrument panel for
the front passenger .
- A capacitive passenger detection system under­
neath the front passenger seat cover. This sys­
tem measures the electrical capacitance of the
person in the seat. The information registered
is sent continuously to the electronic control
unit to regulate deployment of the front Ad­
vanced Airbag on the passenger side .
- An airbag monitoring system and indicator
light in the instrument cluster~
page 154.
-A sensor in each front seat registers the dis­
tance between the respective seat and the steering wheel or instrument panel. The infor­
mation registered is sent continuously to the
electronic control unit to regulate deployment
of the front Advanced Airbags.
- The
PASSENGER AIR BAG OFF light comes on
and stays on in the center of the instrument
panel ~
page 155, fig. 160 and tells you when
the front Advanced Airbag on the passenger side has been turned
off.
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transmits this information to the electronic control unit.
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 prevent 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 1.1'1
N seat or disconnect wires from it. ID ......
Airbag system
-Never carry sharp objects in your pockets or
put them on the seat. The capacitive pas­
senger detection mat in the front passenger
seat will not function properly if it is punc­
tured.
- Never carry things on your lap or carry ob­
jects on the front passenger seat . Such ob­
jects can influence the capacitance regis­
tered by the capacitive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
- Never store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, preventing them and the airbag sys­
tem from working properly.
- Never place 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 child re­
straints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly.
- If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child restraint system on
this seat.
- Never use cushions, pillows, blankets, or
similar items on the front passenger seat .
The additional layers prevent the capacitive
passenger detection system from accurately
measuring the capacitance of the child safe­
ty seat and/or the person on the seat and
thus keep the Advanced Airbag System from
working properly.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heater
for child seats) on the front passenger seat if the device is connected to the 12-volt
socket or the cigarette lighter socket. Such
devices can influence 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
~
151

Airb ag syst em
manufacturer's instructions require the use
of a towel, foam cushion or something else
to properly position the child restraint,
make certain that the
PA SSE NGE R A IR BAG
OFF
light comes on and stays on whenever
the chi ld restraint is insta lled on the front
passenge r seat.
- If the PA SSEN GER AIR BAG OFF light does
not come on and stay on, immed iate ly in­
sta ll c hild restra int in a rear seating position
and have the a irbag system inspected by
your Audi dealer .
_& WARNING
If the front passenger seat gets we t, dry i t i m­
mediately .
- If liquid soaks into the front passenger sea t,
this can keep the airbag system from work ­
ing properly and may, for instance, deacti­
vate the passenger frontal airbag. If th is
happens, the
PASSENGER AIR BAG OFF
light will come on and stay on together with
the airbag ind icator light
fl in the inst ru­
ment cluster.
- If liquid is poo led on the seat, but has not
soaked in, this may a lso keep the airbag sys ­
tem from work ing properly and cause the
passenge r frontal a irbag to be enab led
(turned on), even tho ugh there is a properly
insta lled child restraint system on the sea t.
Wet towels or other wet things on the seat cus hion can have the same effect .
If the
front passenger fronta l airbag is turned on,
the
PASSENGER AIR BAG OFF light light
will go out.
How the Advanced Airbag System
components work together
The fron t Advanced A irbag System and the s ide
a ir bags s upplement the prote ction offered by the
front three-point s afety be lts wi th pre tensioners
a nd load limiters and the adjustable head re ­
straints * to he lp red uce the risk of i njury in a
wide range of acc ident and crash situations . Be
sure to read the important informat ion about
safety and heed the WARNINGS in this chapter.
152
Deployment of the Advanced A irbag System and
the activation of the safety belt pretensioners de­
pend on the dece leration meas ured by the crash
sensors and registered by the electronic control unit. Crash severity depends on speed and decel­
eration as we ll as the mass and stiffness of the
vehicle or object involved in the crash .
On the passenger side, regardless of safety belt
use, the front passenger frontal airbag will be
turned
off if the electrical capacitance measured
by the capacitive passenge r detection system on
the front passenger seat is less than the amount programmed in the electronic cont rol uni t. T he
fron t passenger frontal airbag will a lso be turned
off if the capac itance meas ured by the sys tem 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
PA SSENGER AIR BAG OFF light comes
on a nd stays on to tell you when the front Ad ­
vanced Airbag System on the passe nger side has
been t urned
off ¢ page 155.
_& WARNING
To reduce the ris k of inj ury w hen an a irbag i n­
fla tes, a lways wear safety belts prope rly.
- If you are unrestra ined, leaning forward, sit­
ting sideways or out of posit io n in any way,
your r isk of injury is much higher.
- You will also receive se rious injuries and
co uld even be killed if yo u are up ag ains t t he

A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the a irbag unfo lds or by be­
ing 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 passenger seat. Objects could
move into the area of the front airbags dur­
ing braking or other sudden maneuvers and
become dangero us projectiles that can
ca use serio us pe rsonal injury if the airbags
inflate.
- Never place or attach accessor ies or other
objects (such as cup holde rs, telephone
brackets, large, heavy or bu lky objects) on
the doors, over or near the area marked "AIRBAG" on the steer ing whee l, instru­
ment pane l, seat backrests or between
those areas and yourse lf. 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 or the front air­ bag during braking or in a sudden maneu­
ver. Objects near t he airbags c an become
project iles and cause injury, part icularly
when the seat is reclined .
- Never place or transpo rt obje cts on the
fron t passenger seat . Objects on the front
passenge r seat co uld 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 person on the seat
is heav ier than he or she actually is . The
change in elect ric capac itance because of
s uch objects can cause the passenger front
airbag to be turned on when it should be off,
or can cause the airbag to work in a way that
is diffe ren t from the way it would have
worked without objects on the sea t.
- Always make sure that there is no thing on
the front passenger sea t that will cause the
capacit ive passenger detection system in
the seat to signa l to the Airbag System that
154
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 actua lly
sitt ing on the seat . The presence of an ob­
ject could ca use the passenger front a irbag
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
wo rked witho ut the ob ject on the seat.
A WARNING
-
T he fine dus t created when airbags deploy can
cause breathing pro blems for people with a
h istory of asthma or other breath ing condi­
tions.
- To reduce the risk of breathing p roblems,
those with asthma o r other respiratory con­
ditions sho uld get fresh air 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 w ith m ild
soap and water before eat ing .
- Be careful not to get the dust into your eyes,
or into any cuts or scratches .
- If the resid ue should get into your eyes,
flush them w ith water.
Monitoring the
Advanced Airbag System
t!i Airbag monitoring indicator light
Two separate indicators monitor the function of
the Advanced Airbag System: the airbag moni ­
toring indicator light and the

BAG OFF
light.
The Advanced A irbag System as well as the side
airbags and side curtain airbags wit h ejection
mitigation features (incl uding the e lectronic con ­
trol unit, sensors and system w iring) are all
monitored continuously to make sure that they
are funct ioning properly whenever the ign ition is
o n. Every t ime you turn on t he ignit io n, the air ­
bag system indicato r light
fl will come on fo r a
few seconds (fun ct ion check).

@ For the sake of the environment
Undeployed airbag modu les and pretension­
ers might be classified as Perchlorate Mater ial
- 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 w ith pretens ioners 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 yo u.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag System
performs in a crash. For example, using tire-rim
comb inat ions not approved by Audi, lowering the
vehicle, changing the stiffness of the su spension,
including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
e lectronic control un it. 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.
_& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in ­
crease the risk of ser ious personal injury in a
crash.
- Never install suspens ion components that
do not have the same performance charac­
teristics as the components originally instal­
led on your veh icle.
- Never use tire-rim combinations that have
not been approved by Audi.
Airbag system
Knee airbags
Description of knee a irbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants .
Fig. 161 D river 's knee a irbag
T he driver knee airbag is in the instrument panel
underneath the steering wheel
¢fig.161, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec­
tion provided by the safety belts.
If the front airbags dep loy, the knee airbags also
deploy in frontal collisions when the dep loyment
threshold stored in the control unit is met
¢ page 152 , More important things to know
about front airbags .
In addition to their normal safety function, safe­
ty belts help keep the driver or front passenger in
position in a frontal collision so that the airbags
can provide supplemental protection .
The airbag system is not a substitute for your
safety belt . Rather, it is part of the overall occu­
pant restraint system in your vehicle. Always re­
member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly. This is why you should a l­
ways wear your safety belt, not just because the
law requires you to do so¢

Airbag syste m
-the e lectronic control module and external side
impact sensors
- the two airbags located in the sides of the front
backrests and the two airbags* located in the
rear backrest
- the ai rbag warning light in the inst rument cl us-
ter .
The a irbag system is monitored electron ica lly to
make certa in that it is function ing properly at a ll
times. Each time you switch on the ignition, the
airbag system indicator light will come on for a
few seconds (self diagnostics).
The s ide a irbag system supplements the safety
be lts and can he lp to reduce the risk of injury to
the driver 's, front and rear passenger 's upper tor­
so on the side of the vehicle that is struck in a
side collision. The airbag deploys only in side im­
pacts and on ly when the vehicle accelera tion reg­
istered by the control unit is high enough . If this
rate is below the reference value programmed in­
to the contro l unit , the side airbags will not be
tr iggered, even though the car may be badly
damaged as a result of the co llision.
It is not pos ­
sible to def ine an a irbag tr igger ing range that
will cover every possible angle of impact, since
the circumstances wi ll vary considerably between
one co llision and another. Important factors in­
clude, for example, the nature (hard or soft) of
t he impacting object, the angle of impact, vehicle
speed, etc. ¢
page 163, Important safety in ­
structions on the side airbag system.
Aside from the ir norma l safety function, safety
be lt s work to help keep the dr iver or front pas­
senger in pos it ion in the event of a s ide collision
so that the side a irbags can provide protect ion.
The airbag system is
not a subst itute for your

be lt and wearing it p roperly. This is another rea­
son why you shou ld always wea r you r safety
be lts, not just because the law requ ires you to do
so ¢
page 135, General information.
It is important to remember that while the sup­
p lemental side airbag system is des igned to re-
162
duce the like lihood of serious injur ies, other inju­
ries , for example, swelling, bruising, friction
burns and m inor abrasions can a lso be associated
with deployed side airbags. Remember too, s ide
airbags will dep loy only once and only in certain
k inds of accidents -your safety belts are always
the re to offer protection .
Vehicle damage, repair costs or even the lack of
vehicle damage are no t necessarily an indication
of over-sensitive or failed airbag activation . In
some collis ions, both front and side ai rbags may
i nflate . Remember too, that a irbags w ill deploy
o nl y once and on ly in certa in kinds of collisions -
you r safety be lts a re a lways there to offer p rotec­
tion in those accidents in which airbags are not s u pposed to deploy or when they have a lready
deployed.
The side airbag system will not deploy:
- when the ignit io n is swit ched off
- in side co llisions when the accele rat ion meas-
ured by the senso r is too low
- in front-end collisions
-in rear-end collisions
- in rollovers.
In some types of accidents the 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 seating position
¢ page 163.
-If the airbag ind icator light¢ page 18
comes when the veh icle is being used, have
the system inspected immediately by your
author ized Audi dealer .
It is possible that
the airbag will in flate when i t is not sup­

flates.
- Never p lace or attach accessories or other
objects (such as cup holders, telephone brackets, or even large, bulky objects) on
the doors, over or near the area marked "AIRBAG" on the seat backrests.
- Su ch ob jects and ac cessories can become
dangerous projecti les and cause injury
when the supplemental side airbag de ­
p loys .
- Never carry any objects or pets in t he de ­
p loyment space between them and the
airbags or allow chi ldren or other passen­
gers to trave l 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 with side airbag deployment
and can cause personal injury in an accident .
- Always prevent the side a irbags from be ing
damaged by heavy objects knocking against
o r hitting the sides of the seatbacks .
- The airbag system can only be triggered
once . If the airbag has been triggered, the
system must be rep laced by an authorized
Audi dealership.
- Damage (c racks, deep scratches etc.) to the
o rig inal seat covers or to the seam in the
area of the side airbag module must a lways
be repaired immedia tely by an authori zed
Audi dealer .

Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide sup­
plemental protection to properly restrained oc­
cupants .
Fig. 16 5 Sid e curt ain airba gs, dr iver's s ide: side cur tain air­

The side curtai n airbags are located on both sides
of the inter ior above the front and rear side win­
dows
~ fig. 165 . They are identif ied by the word
"AIRBAG" on the windsh ield frame and the cen ­

The side curtai n airbags contain features that
provide ejection mitigation to help prevent vehi ­
cle occupants or parts of their bodies from being
completely or partially ejected from the vehicle
interior in certa in side impacts and ve hicle roll­
ove rs.
The side c urtain airbag system supplements the

It is important to remember that while the side
curta in airbag system is designed to help reduce
the likelihood of serious injuries, other injur ies,
for example , swelling , b ruising, fr iction burns
and minor abras ions can also be associated with
these airbags upon deployment . Remember too,
these airbags will deploy only once and only in
