seat backrests; never place them between
these areas and you or any other person in
the vehicle.
- Never attach objects to the windshield
above the passenger front airbag, such as
accessory GPS navigation units or music
players. Such objects could cause serious in ­
jury in a collision, especially when the air­ bags inflate .
A WARNING
A person on the front passenger seat, espe­
cially infants and small children, will receive
serious injuries and can even be killed by be­
ing too close to the airbag when it inflates.
- Although the Advanced Airbag System in
-
your vehicle is designed to turn off the front
passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un­
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle.
- The Advanced Airbag System can deploy in accordance with the "low risk" option under
the U .S . Federal Standard if a child that is
heavier than the typical one-year old child is
on the front passenger seat and the other
conditions for airbag deployment are met.
- For its own safety, a child should always ride
properly restrained for its age and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United States
Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.
The front Advanced Airbag System supplements
the safety belts to provide additional protection
for the driv er's and front passenger's heads and
upper bodies in frontal crashes . The airbags in­
flate only in frontal impacts when the vehicle de­
celeration is high enough.
Airbag system
The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety
belts. Rather, it is part of the overall occupant re­
straint system in your vehicle. Always remember
that the airb ag system can only help to protect
you, if you are sitting upright, wearing your safe­
ty belt and wearing it properly . This is why you
and your passengers must always be properly re­
strained, not just because the law requires you to
be.
The Advanced Airbag System in your vehicle has
been certified to meet the "low risk" require­
ments for 3 and 6 year-old children on the pas­
senger side and very small adults on the driver
side. The low risk deployment criteria are intend­
ed to help reduce the risk of injury through inter­
action with the front airbag that can occur, for
example, by being too close to the steering wheel
and instrument p anel when the airbag inflates.
In addition, the system has been certified to
comply with the "suppression" requirements of
the Safety Standard, to turn off the front airbag
for infants 12 months old and younger who are
res trained on the front passenger seat in child re­
straints that are listed in the Standard
~page 218, Child restraints and Advanced front
airbag system .
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is restrained
on the front passenger seat in one of the rear­
facing or forward-facing infant restraints listed in Federal Motor Vehicle Safety Standard 208
with which the Advanced Airbag System in your
vehicle was certified . For a listing of the child
restraints that were used to certify your vehi­
cle's compliance with the US Safety Standard
~page 218,
- When a person is detected on the front passen­
ger seat that has an electrical capacitance that
is more than the total electrical capacitance of
a child that is about 1 year old restrained in one
of the rear-facing or forward-facing infant re­
straints (listed in Federal Motor Vehicle Safety
Standard 208 with which the Advanced Airbag
System in your vehicle was certified), the front

airbag on the passenger side may or may not
deploy.
The
PAS SENGER AIR B AG OFF ~; light comes o n
when the e lectron ic control un it detects a total
e lectrica l capacitance on the front passenger seat
that requires the front airbag to be turned
off . If
the
PASSENGER AIR BAG OFF '1; light does not
come on, the front airbag on the passenger side has not been turned
off by the control unit and
can deploy if the control unit senses an impact
that meets the conditions stored in its memory .
If the tota l electrical capac itance registered on
the front passenger seat is more than that of a
typical 1 year -old, but less than the weight of a
small adult , the front airbag on the passenger
side may deploy (the
PASSENGER AIR BAG OFF
~ ; light does not come on).
For exampl e, th e airbag may d eploy if:
- a small child that is heavier than a typical 1
year-old ch ild is on the front passenger seat
(regardless of whether the child is in one of the
ch ild seats listed
r=;,page 218),
- a chi ld who has outgrown child restraints is on
the front passenger seat .
If the front passenger airbag is turned off , the
P ASS ENGER AIR BA G OFF~; light in the head­
liner will come on and stay on .
I f the front passenger airbag dep loys, the Feder ­
a l Standard requires the airbag to meet the "low
risk" deployment criteria to help reduce the risk
of injury through interaction with the airbag.
"Low risk" deployment occurs in those crashes
that take place at lower decelerations as def ined

Alw ays remember: Please be sure to read the im­
portant information in the sections that follow
and be sure to heed all of the WARNINGS .
A WARNING
To red uce the risk of inju ry when an a irbag in­
flates, a lways wear safety belts p roperly.
- If you are unrestrained, lean ing forward, s it­
t ing s ideways or out of pos ition in any way,
yo ur r isk of i njur y 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 inflates -
eve n with a n Advanced
Airbag ¢ page 194.
A WARNING
A child in a rearward-facing child seat instal­
led on t he front passenger seat will be seri­
ously injured and ca n be killed if the front air­
bag inflates -even with an Advanced Airbag
Sys tem.
- Altho ugh the Advanced Airbag System in
your veh icle is des igned to tur n
off the front
air bag w hen a rearward -fac ing c hild re ­
s traint has been installed on the front pas­
senger seat, nobody can abso lute ly guaran ­
tee t hat dep loyment is impossib le in all con ­
ceivab le situat ions that may happen d uring
the useful life of your vehicle.
- The inflating airbag will h it the ch ild seat or
infant carrier with great force and will
smash the child seat and child against the backrest, center armrest, door, or roof .
- If you m ust install a rearward facing child
safety seat on the front passenger seat be­
cause of except ional circ umstances and the
PASSENGER AIR BAG OFF ~; light does not
come on and stay on have t he a irbag system
inspected by yo ur Audi dea ler.
A WARNING
I f, in exceptional c ircumstances , you must in ­
s tall a forward -fa cing ch ild res trai nt on the
front passenger's seat:
- Always make sure the forward -fa cing sea t
has bee n des igned and certified by its man ­
ufacturer for use on a front seat with a pas ­
senge r front and side airbag.
- Never put the fo rward -facing chi ld restrain t
up against o r very near the instr ument pan ­
el.
- Always move the front passenger seat to
the highest position in the up and down ad ­
justment range and move it bac k to the
rearmost posit io n in the seat's fo re and aft

Cl 00 .-< N r--­N .-< 0 r--­Vl 00
adjustment range, as far away from the air­
bag as possib le, before insta lling the for­
ward-facing child restra int.
- Always make sure that the safety belt upper
anchorage is beh ind the child restraint and
not next to or in front of the chi ld restraint
so that the safety belt will be properly pos i­
t ioned.
- Always make sure that there is nothing on
the front passenger seat that w ill cause the
capacit ive passenger detection system in
the seat to signa l to the Airbag System that
the seat is occupied by a person w hen it is
not, or to sign al that it is occ upied by some­
one who is heavier than t he pe rson actua lly
sitting on the seat . The presence of addi­
tiona l objects could ca use the passenge r
front airbag to be turned on when it shou ld
be off, or could cause the airbag to work in a
way that is different from the way it would
have worked wi tho ut the object on t he seat .
- Make sure that the
PASSENGER AIR BAG
OFF ~; light comes on and stays on all the
t ime w henever the ignition is sw itc hed on.
Advanced Airbag System components
The front passenger seat in you r vehicle has a lot
of very impo rtant parts of the Advanced Airbag
Sys tem in it. These pa rts in cl ude the capaci tive
passenger detection system, w iring, brac kets,
and more. The control unit monitors the system
on the front passenger seat when the ignition is
switched on and turns the airbag indicator light
on when a malfunct ion in the one of the system
components is detected
¢ page 206. Because
the front passenger seat contains important
pa rts of the Advanced Airbag System, you must
take ca re to prevent it from be ing damaged .
D amage to the seat may p reve nt the Advanced
A irbag System fo r the fron t passenger seat from
doi ng its job in a crash.
The front Advanced Airbag System consists
of the following :
-Cr ash sensors in the front of the vehicle t hat
measure vehicle accelerat ion/dece lerat ion to
Airbag syste m
prov ide information to the Advanced A irbag
System about the severity of the cras h.
- An electronic contro l uni t, with integrated
cras h sensors for front and side impacts . The
control unit "decides" whether to fire the front
airbags based on the information rece ived from
the crash sensors . The control unit also "de­
cides" whether the safety belt pretensioners
should be activated.
- An Advanced A irbag w it h gas generator for the
driver inside the steering wheel hub .
- An Advanced A irbag w ith gas generator inside
the instrument panel for the front passenger.
- A capacit ive passenger detection system under ­
neat h the front passenger seat cover. This sys­
tem meas ures the e lectr ica l capacitance of the
person in the seat. The informat ion registered
is sent cont inuously to the elect ronic contro l
un it to reg ulate dep loymen t of the front Ad­
vance d Airbag on the p assenger side.
- An airbag monitor ing system and ind icator
ligh t
El in the inst rument cl uste r.
- A sensor in each front seat registe rs the d is­
t ance betwee n the respective seat and the
s teer ing whee l o r i nst rument p anel. The infor­
mation registered is sent con tinuous ly to the
elect ronic contro l unit to regu late dep loyment
of the front Advanced Airbags .
- The
PASSENGER AIR BAG OFF ~; lig ht comes
on and stays on in the
headliner¢ page 206,
fig. 164 and tells you when the front Advanced
Airbag on the passenger side has been turned
off.
- A sensor in the safety be lt latch for the driver
and for the front seat passenger that senses
whether that safety be lt is latched or not and
transmits this information to the e lectronic
control un it .
A WARNING
-
Damage to the front passenge r seat can pre­
vent the front airbag from wo rk ing prope rly.
- Imp roper repair or d isassembly of the front
passenger and driver seat will p reve nt the
Advanced A irbag Sys tem from f unct io ni ng
p roperly .

Airbag syste m
-Repairs to the front passenger seat must be
performed by qua lified and properly trained
workshop personnel.
- Never remove the front passenger or driver
seat from the vehicle.
- Never remove the upho lstery 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
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 capac itance regis­
tered by the capac itive passenger detection
system, so that incorrect information is p ro­
vided to the airbag control unit.
- Never store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger sea t could be dam­
aged, preventing them and the airbag sys­
tem from working properly.
- Never place seat covers o r rep lacemen t up­
holstery that have not been spec ifically ap­
proved by Audi on the front seats.
- Seat covers can prevent the Advanced Air­
bag System from recogn izing child re ­
straints or occupants on the front passenge r
seat and prevent the side airbag in the seat
backrest from dep loying properly.
- If a seat heater has been retrofitted or oth­
erwise added to the front passenge r seat,
never install any ch ild restraint system on
this seat.
- Never use cush ions, pillows, blankets, or
similar items on the front passenger seat.
The add it iona l layers prevent the capacitive
passenger detection system from accurate ly
measuring the capac itance of the ch ild safe­
ty seat and/or the pe rson on the seat and
th us keep the Advanced Airbag System from
wor king p roperly.
- Never place o r use any electrical device
(s uch as a laptop, CD player, elect ronic
games dev ice, power inverter or seat heater
202
for child seats) on the front passenger seat
if the device is connected to the 12-volt
socket or the cigarette lighter socket. Such
dev ices can influence the capac itance regis­
tered by the capacitive passenger detection
system, so that incorrect informat ion is pro­
vided to the airbag cont rol unit.
- If you must use a child restra int on the fron t
passenger seat and the child restraint man­
ufacturer's instructions requ ire the use of a
towel, foam c ushion or someth ing else to
proper ly posit ion the child res tra int, ma ke
certain that the
PASSENGER AIR BAG OFF
~ ; light comes on and stays on whenever
the child restraint is installed on the front
passenger seat.
- If the
PASSENGER AIR BAG OFF ~; light
does not come on and stay on, have the air­ bag system inspected by your Audi dealer.
A WARNING
If the front passenger seat gets wet, dry it im­
mediately .
-If liquid soaks into the front passenger seat,
this can keep the airbag system from work­
ing properly and may, for instance, deacti­
vate the passenger frontal airbag.
If this
happens, the
PASSENGER AIR BAG OFF ~'
light will come on and s tay on together w ith
t he air bag indica to r li gh t
El in the instru­
ment cluster .
- If liqu id is pooled on the sea t, but has not
soaked in, th is may also keep the airbag sys­
tem from wor king p roper ly and cause the
passenger fronta l airbag to be enabled
(turned on), even though there is a properly
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.

front three-point safety belts to help reduce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the important
information about safety and heed the WARN­
INGS in this chapter.
Deployment of the Advanced A irbag System and
the activation of the safety belt pretensioners de­
pend on the deceleration measured by the crash
sensors and registered by the electronic control
unit . Crash severity depends on speed and decel ­
eration as well 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 passenger detection system on
the front passenger seat is less than the amount
programmed in the electronic control unit. The
front passenger frontal airbag will 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 child seats
that was used to certify the Advanced Airbag Sys­
tem under Federal Motor Vehicle Safety Standard
208. The
PASSENGER AIR BAG OFF '1; light
comes on and stays on to tell you when the front
Advanced Airbag System on the passenger side
has been turned off
Q page 206.
A WARNING
To reduce the risk of injury when an airbag in­
flates, always wear safety belts properly.
- If you are unrestrained, leaning forward, sit­
ting sideways or out of position in any way,
your risk of injury is much higher.
- You will also receive serious injuries and
could even be killed if you are up against the
airbag or too close to it when it inflates
-
even with an Advanced Airbag Qpoge 194.

More important things to know about front
airbags
Fig. 163 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfold properly and provide sup­
plemental protection in a frontal collision.
The front airbags are designed to provide addi­
tional protection for the chest and face of the
driver and the front seat passenger when:
- safety belts are worn properly,
- the seats have been positioned so tha t the oc-
cupant is properly seated as far as possible
from the airbag.
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 dangerous pro ­
jectiles, and be pushed into you if the airbag in­
flates.
When an airbag 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
could irritate skin.
It is important to remember that while the sup ­
plemental airbag system is designed to reduce
the likelihood of serious injuries, other injuries,
for example swelling, bruising and minor abra­
sions, can also happen when airbags inflate. Air­
bags do not protect the arms or the lower parts
of the body. Front airbags supp lement the three
point safety belts only in some frontal collisions
in which the vehicle deceleration is high enough
to deploy the airbags.

Airbag syste m
Front airbag s will not d eploy:
- i f the ig nition is switched off whe n a cr ash oc-
cu rs,
- i n s ide collisions,
- in rear-end collisions,
- in rollovers,
- when the crash decelerat ion measured by the
airbag system is less than the minimum thresh ­
old needed for airbag deployment as registered
by the electronic contro l unit .
The front p assenger airb ag will also not
deploy:
- when the front passenger seat is not occup ied,
- whe n the electrical capac itance measured by
the capacitive passenger detect ion system for
the front passenger seat indicates that the pas­
senger side frontal airbag must be switched off
by the electronic contro l unit (the
PASSENGER
A IR BAG
OFF ~; ligh t~ page 206 and how
they work comes on and stays on) .
.&_ WARNING
Sitting in the wrong position can increase the
risk of serious injury in crashes.
- To reduce the risk of injury when the airbags inflate, the driver and passengers must al­
ways sit in an upright position, must not
lean against or p lace any part of their body
too close to the area where the airbags are located.
- Occupants who are unbelted, out of position
or too close to the a irbag can be seriously
injured by an airbag as it unfolds with great
force in the b link of an
eye <=;> page 195.
.&_ WARNING
A child in a rearward-facing chi ld seat insta l­
led on the front passenger seat will be ser i­
ously inju red and can be killed if the front air­
bag inflates
-even with an Advanced Airbag
System.
- T he inflating a irbag w ill hit the child seat or
infant carrier with great force and will
smash the chi ld seat and child against the
backrest, center armrest, door or roof.

- Never install a rearward facing chi ld safety
seat on the front passenger seat unless the
PAS SEN GER AIR B AG OFF ~; light comes
on and stays on . If the
PA SSENGER AIR
BAG
OFF ~; light does not come on and stay
on, the inflat ing airbag will hit the chi ld
safety seat or infant carrie r wi th great force
and will smash the child safety seat and
child against the bac krest, door or roof .
Have the airbag system inspected immedi­
ately by your authorized Audi dealer .
.&_ WARNING
Objects between you and the airbag will in­
crease the r isk of injury in a crash by interfer­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates.
- Never hold things in your hands or on your lap when the veh icle 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 maneuver and
become dangerous projectiles that can
cause serious persona l injury if the airbags
inflate.
- Never place or attach accesso ries o r othe r
objects (such as cup holders, telephone brackets, large, heavy or bulky ob jects) on
the doo rs, ove r or near the area ma rked
"AIRBAG" on the steering wheel, instru ­
ment panel, seat backrests or between
those areas and yourself. These objects
could cause injury in a crash, especially
when the a irbags inflate.
- Never recl ine the front passenger's seat to
transport objects. Items can also move into
the area of the side a irbag or the front air­
bag during brak ing or in a sudden maneu­
ver. Objects near the airbags can become projecti les and cause injury, part icularly
when the seat is reclined.
- Never p lace or t ransport objects on the
-
front passenger seat. Objects on the front
passenger seat could ca use the capaci tive
sensor in the seat to signal to airbag system
that the seat is occ upied by a person when it

in fact is not, or that the person on the seat
is heavier than he or she actually is. The
c h ange in electric capac itance b ecause o f
such obj ects can caus e the passenger front
airbag to be turned on when it should be
off, or can cause the a irbag to wo rk in a way
that is diffe rent from the way it would have
wor ked witho ut objec ts on the se at.
- Always make sure that the re is nothing on
the fron t passenger sea t that w ill cause the
c apa citi ve passenger dete ction system in
the seat to sign al to the Airbag Sys tem tha t
the seat is occupied by a person when it is not, or to signa l that it is occ upied by some­
one who is heavier than the person actually
sitting on the seat. The presence of an ob­
ject could cause the passenger front a irbag
to be t urned on when it sho uld be off, or
cou ld cause the ai rbag to wo rk in a way that
is d ifferent from the way it wou ld have
wor ked witho ut the ob je ct on the seat.
A WARNING
The fine dust cre ate d when air bag s d eploy can
c ause bre athing problems for peop le w ith a
history of asthma or other breathing condi ­
tions .
- T o reduce the risk of brea thing pro blems,
those w ith asthma or other respiratory con ­
ditions should get fresh air right away by
gett ing out of the veh icle or opening w in­
dows o r doors.
- If you are in a collision in which airbags de­
ploy, wash your hands and face with mild
soap and water before eat ing.
- Be careful not to get the dust into your eyes,
o r into any cuts or sc ratches.
- If the resi due should get into your eyes,
flush them with water .
