146 Airbag system
-Always carefully follow instructions from
child restraint manufacturers when in­
stalling child restraints.
_& WARNING
If, in exceptional circumstances, you must
install a forward or rearward -facing child
restraint on the front passenger's seat:
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
tion.
- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child -even with an Advanced Airbag
System.
- Always carefully follow the manufactur­
er's instructions provided with the child
seat or carrier .
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenger detection
system in the seat to signal to the Airbag
System that the seat is occupied by a person when it is not, or to signal that it
is occupied by someone who is heavier
than the person actually sitting on the
seat . The presence of additional objects
could cause the passenger front airbag
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 wou ld
have worked without the object on the
seat.
Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occupants .
Fig. 159 Locat io n of drive r ai rbag: in steering wh eel
Fig. 160 Locat io n of fron t passenger' s air bag: in the in·
st rument panel
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time your
vehicle was manufactured. The system senses
the position of the front seats and controls
front airbag inflation with a valve , depending
on the distance between the respective seat
and the steering wheel or instrument panel.
The safety belts for the seats have "preten­
sioners" that help to take slack out of the belt
system. The pretensioners are also activated by the electronic control uni t for the airbag
system .
The front safety belts also have load limiters
to help reduce the forces applied to the body in a crash.
The airbag for the driver is in the steering
wheel hub¢
fig. 159 and the airbag for the
front passenger is in the instrument panel

q fig. 160. The general location of the airbags
is marked "AIRBAG".
There is a lot you need to know about the air­ bags in your vehicle. We urge you to read the
detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature.
Please be sure to heed the WARNINGS -they
are extremely important for your safety and
the safety of your passengers, especially in ­
fants and small children .
A WARNING
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only supplemental protection .
- Airbag work most effectively when used
with properly worn safety belts .
- Therefore, always wear your safety belts
and make sure that everybody in your ve­
hicle is properly restrained .
- Always hold the steering wheel with both
hands on the outside of the steering
wheel rim at the 9:00 o'clock and 3:00 o'clock positions to help reduce the risk
of personal injury if the driver's airbag in­
flates.
- Never hold the steering wheel at the 12
o'clock position or with your hands any­
where inside the steering wheel or on the
steering wheel hub. Holding the steering
wheel the wrong way increases the risk
of severe injury to the arms, hands, and
head if the driver airbag deploys .
A WARNING
Objects between you and the airbag will
increase the risk of injury in a crash by in­
terfering with the way the airbag unfolds
and/or by being pushed into you as the air­
bag inflates.
- Always make sure nothing is in the front
airbag deployment zone that could be
struck by the airbag when it inflates.
- Objects in the zone of a deploying airbag
can become projectiles when the airbag
Airbag system 147
deploys and cause serious personal in­
Jury.
- Never hold things in your hands or on
your lap when the vehicle is in use.
- Never place accessories or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or bulky) on the
doors; never attach then to the doors or
the windshield; never place them over or
near or attach them to the area marked
,,AIRBAG" on the steering wheel, instru­
ment panel or the 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 mu­
sic players. Such objects could cause seri­
ous injury in a collision, especially when
the airbags inflate.
- Never recline the front passenger seat to
transport objects. Items can also move
into the deployment area of the side air­
bags or the front airbag during breaking
or in a sudden maneuver. Objects near
the airbags can fly dangerously through
the passenger compartment and cause injury, particularly when the seat is re­
clined and the airbags inflate.
WARNING
A person on the front passenger seat, es­
pecially infants and small children, will re­
ceive serious injuries and can even be kil­
led by being 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 under these special conditions is impossible in all conceiva­
ble situations that may happen during
the useful life of your vehicle . .,.

148 Airbag system
-The Advanced Airbag System can deploy
in accordance with the .,low risk" option
for 3- and 6-year-old children under the U.S . Federal Standard if a child with elec­
trical capacitance greater than the com­ bined capacitance of a typical one-year
old infant restrained in one of the for­
ward facing or rearward-facing child
seats with which your vehicle was certi­
fied is on the front passenger seat and
the other conditions for airbag deploy­ ment are met.
- Accident statistics have shown that chil­
dren are generally safer in the rear seat
area than in the front seating position.
- For their own safety, all children, espe­
cially 12 years and younger, should al­
ways ride in the back properly restrained
for their 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
208 as applicable at the time your vehicle was manufactured.
The front Advanced Airbag System supple ­
ments the safety belts to provide additional
protection for the driver's and front passeng­
er's heads and upper bodies in frontal crashes .
The airbags inflate only in frontal impacts
when the vehicle deceleration is high enough.
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts. Rather, it is part of the over­ all occupant restraint system in your vehicle.
Always remember that the airbag system can
only help to protect you, if you are sitting up­
right, wearing your safety belt and wearing it
properly . This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your vehicle has been certified to meet the "low risk" re­
quirements for 3 and 6 year-old children on
the passenger side and very small adults on the driver side. The low risk deployment crite­
ria are intended to help reduce the risk of in­
jury through interaction with the front airbag
that can occur, for example, by being too close to the steering wheel and instrument
panel 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 restrained on the front passenger
seat in child restraints that are listed in the
Standard
c::> page 170, 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 re­
strained 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 Ad­
vanced Airbag System in your vehicle was
certified. For a listing of the child restraints
that were used to certify your vehicle's com­
pliance with the US Safety Standard
i=>page 170,
-When a person is detected on the front pas­
senger seat that has an electrical capaci­
tance 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 restraints (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 de­
ploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to­
tal electrical capacitance on the front passen­ ger seat that requires the front airbag to be
turned off. If the
PASSENGER AIR BAG OFF
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 condi -
tions stored in its memory. ..,_

posit ion.
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenger detection
system in the seat to s ignal to the A irbag
System that the seat is occupied by a
person when it is not, or to signal that it
is occupied by someone who is heavier
than the pe rson actually s itting on t he
seat. The presence of additiona l objects
cou ld cause the passenger front airbag
to be t urned on w hen it sho uld be off, or
cou ld cause the airbag to work in a way
that is different from the way it wou ld
have worked without the object on the
seat.
- Make sure that the

on.
Advanced Airbag System components
The front passenger seat in you r veh icle has a
l ot of very important pa rts of the Advanced
A irbag System in it . These parts include the
capacitive passenge r de tect ion sys tem, wir­
ing, brac kets, and more . The cont ro l uni t
monitors the system on the front passenger
seat when the ignition is switc hed on and
turns the airbag indicato r light on when a
malfunction in the one of the system compo­
nents is detected
c::;, page 155 . Because the
fro nt passenge r seat contains important pa rts
of the Advanced Airbag System , you must
take ca re to p revent it from being damaged.
Da mage to the seat may preven t the Ad­
vanced A irb ag System for the fron t passenger
seat from doing i ts job in a c rash .
The front Advanced Airbag System
consists of the following:
-Crash sensors in the front o f the veh icle tha t
measure veh icle acceleration/dece le ration
to provide information to the Advanced Air­ bag System about the severity of the crash. -
An elect ronic contro l unit, with integrated
crash sensors for front and sid e impacts .
T he control un it "decides" whether to fire
the front a irbags based on the inform at ion
received from the crash sensors. The control
unit also "decides" whether the safety belt prete nsioners shou ld be act ivated .
- An Advanced A irbag w ith gas generator and
contro l valve for the driver inside the steer­
ing wheel hub .
- An Advanced A irbag w ith gas generator and
contro l valve inside the inst rument panel for
the front passenger .
- A capacit ive passenger detection system u n­
de rneath the front passenger seat cover .
This system measures the elec trical capac i­
t ance of the perso n in t he seat. The informa ­
t ion regis tered is se nt cont inuo usly to the
electronic con trol un it to regu late deploy­
ment of the front Advanced Airbag on the
passenger side.
- An airbag monitoring system and indicator
light in the instr ument cluster
c::;, page 154.
- A senso r in each front seat regis ters the dis­
tance between the respective seat and the
steering whee l or instrument panel. The in ­
formation registered is sent cont inuo usly to
the electron ic contro l uni t to regulate de­
ployment of the front Adv a need A irbags .
- The
PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instr u­
ment panel
c::;, page 155, fig . 162 and tells
you when the front Advanced Airbag on the
passenger side has been t urned off.
- A sensor in the safety belt latch for the driv­
er and fo r the front seat passenger that
senses w hether t hat safety belt is latched or
no t and transmi ts this information to t he
elec tronic con trol un it.
A WARNING
D amage to the fron t passenger seat can
prevent the front airbag from working
p roperly.
- Imp roper repai r or disassembly of the
front passenge r and dr iver seat will pre­
vent the Advanced Airbag System from
functioning properly .
-

things on the sea t cushion can have the
same effect. If the front passenger fron­ tal airbag is turned on, the
PASSENGER
AIR BAG OFF
light light will go out .
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side airbags supplement the protection of­
fered by the front three -point safety be lts
with pretensioners and load limiters and the
adj ustab le head restraints* to help reduce the
risk of inju ry in a wide range of accident and
crash situa tions. Be sure to re ad the impor­
tan t information abou t safe ty and heed the
WARNINGS in this chapter .
Dep loyment of the Advanced Airbag System
and the activat ion of the safety bel t preten­
sioners depend on the decelera tion measured
by the crash sensors and registered by the
e lectronic control un it . The amount of i nfla­
tion of the front airbags can also be adapted to the front sea t position , depend ing on the
d istance between t he respective front seat
and the steering wheel o r instrument pa nel as
registered by sensors in the seats. Crash se­
ver ity depends on speed and dec elerat ion as
well as the mass and st iffness of the vehicle
or objec t invo lved in the crash .
On the passenge r side, regard less of safety
be lt use, the front passenger fronta l a irbag
will be turned off if the e lectrical capacitance
measured by the capac itive passenger de tec­
tion system on the front passenger seat is less
than the amount programmed in the electron ­
i c co ntrol unit . The front passenger frontal air­
bag will a lso be turned off if the capa cita nce
measured by the system for the front passen­
ge r seat eq ua ls tha t of an infant of abo ut one
yea r of age in one o f the child sea ts that was
used to cert ify the Advanced Airbag System
under Federal Motor Vehicle Safety Standard
208. The
PASSENGER AIR BAG OFF li ght
comes on and stays on to tell you when the
front Advanced A irbag System on the passen­
ge r side has been turned off~

A WARNING
-To reduce the risk of injury w hen an a irbag
in flates, always wear safety be lts p roperly.
- If you are unrestra ined, leaning fo rward,
sitt ing s ideways or out of pos ition in any
way, your risk of injury is much h igher .
- You will a lso receive se rious injuries and
could even be killed if you a re up aga inst

When an airbag deploy s, fine dust is re leased.
This is norma l and is not caused by a f ire in ..,.

154 Airbag sys te m
- Never place or attach accessories or o th­
er objects (such as cup holders, tele­
phone brackets, large, heavy or bulky ob­
jects) on the doors, over or near the area marked "AIRBAG" on the stee ring 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 passenger'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 whe n it in fa ct is not, o r that
the person on the se at is heavie r than he
or she actually is. The change in electric
capacitance because of such objects can
cause the passenger front airbag to be
t u rned 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
wor ked w ithout ob jects 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 occupied by a
person when it is not, or to signa l th at it

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
- If the status of the Adva need A irbag Sys­
tem has changed wh ile the vehicle is
moving, the
PASSENGER AIR BAG OFF
light b links for about 5 seconds to catch
the driver's attent ion. If this happens, al­
ways stop as soon as it is safe to do so
and check the steps described above.
- If the PASSENGER AIR BAG OFF light
does not go off when an adu lt who is not
very small is sitting on the front passen ­
ger seat after taking the steps described
above, make sure the adult is properly
seated and restrained at one of the rear
seating pos it ions. Have the airbag sys­
tem inspected by your authorized Audi
dealer before transpo rting anyone on the
front passenger seat.
A WARNING
An airbag system that is not funct ioning
prope rly cannot provide supplemental p ro­
t e ction in a fron tal crash.
- If the airbag indicato r light ~page 18
comes when the vehicle is be ing used,
h ave the system inspected immedi ately
by you r autho rized Aud i dea ler . It is pos­
sible that the airba g will inflate when it

is not supposed to, or will not inflate
when it should.
A WARNING
If the front airbag inflates, a child without
a child restraint, or in a rearward-facing
chi ld safety seat, or in a forward-facing
chi ld restraint that has not been proper ly
install ed w ill be seriou sly injur ed and can
be killed.
- Even tho ugh yo ur vehicle is equipped
wit h an Advanced A irbag System, make
certain that all children, espec ial ly 12
ye ars and younger, always ride on the
back seat properly rest rained for their
age an d size .
- Always install forward o r rear-facing
child seats on the rear sea t - even with
an Advanced Ai rba g System.
- If you must install a rearwa rd -fa cing
child seat on the front passenger seat because of exceptional circumstances
and the

How knee airbags work
Applies to vehicles: with knee airb ags
The risk of injury to the leg area can be re­
duced by fully inflated knee airbags.
Fig. 164 Inflated airbags protecting in a frontal coll i­
sio n
The knee airbag system has been designed so
that the airbags for the driver and front pas­
senger deploy in certain but not all frontal
collisions .
If the front airbags deploy, the knee airbags
also deploy in frontal collisions when the de­ ployment threshold stored in the control unit
is met .
When the system deploys, the airbags fill
with a propellant gas, and inflate between the lower part of the instrument panel and the
driver and the lower part of the instrument panel and the front passenger¢
page 152,
fig. 161.
Although they are not a soft pillow, they can
"cush ion" the impact and in this way they can
help to reduce the risk of injury to the lower
extremities.
All of this takes place in the blink of an eye, so
fast that many people don't even realize that
the airbags have deployed . The airbags also
inflate with a great deal of force and it is im­
portant for occupant safety that nothing
should be in their way when they deploy.
Fully inflated airbags in combination with
properly worn safety belts slow down and lim­
it the occupant's forward movement and help
to reduce the risk of injury.
Airbag system 161
Important safety instructions on the
knee airbag system
Applies to vehicles: wit h knee airbags
Airbags are only supplemental restraints . Al­
ways wear safety belts correctly and ride in a
proper seating position.
There is a lot that you and your passengers
must know and do to help the safety belts and
airbags to provide supplemental protection.
_&. WARNING .. -
An inflating knee airbag can cause serious injury. Wearing safety belts incorrectly and
imprope r seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you a re seated too close
to any of the airbag locations. When ad­
justing their seat positions, it is impor­
tant that both the driver and the front passenger keep their upper bodies and
knees at the following minimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru­
ment panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru­
ment panel.
- The risk of personal injury increases if
you lean forward or to the side, or if the seat is improperly positioned and you are
not wearing your safety belt . The risk in­
creases even more should the airbag de­
ploy.
- Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter­
fering with the way the airbag deploys or
by being pushed into you as the airbag
deploys.
- Never let anybody, especially children
or animals ride in the footwell in front

Always 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 why you should always wear
your safety belts, not just because the law re­
qu ires you to do soc>
page 133, General
notes.
It is important to remember that while the
supp lemental s ide airbag system is designed
to reduce the like lihood of serious injur ies,
other i njuries, for example, swel ling, b ruising,
frict ion bu rns and minor ab rasions can also be
assoc ia ted with deployed side airbags. Re­
member too, side airbags will deploy only
once and only in certain kinds of accidents -
your safety belts 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
airbags 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 airbags are not supposed to
deploy or when they have already deployed.
The side airbag sy stem 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 collisions
- 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 b e
tr iggered toge ther.
_& WARNING
- Saf ety belts and the a irbag system will
only prov ide protection when occ upan ts
are in the proper seating posit ion
c>page 164.
- If the airbag indicator light c> page 18
comes when the vehicle is being used,
-
Airba g sy stem 163
have the system inspected immediately
by your authorized Audi dealer.
It i s pos­
sible that the airbag will inflate when it
is not supposed to, or will not inflate
when it should.
How supplemental s ide airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained .
Fig. 16 6 In flated side airbags on left side of vehicle,
rear side airbag
When the system is triggered, the airbag is
filled with propellant gas and breaks through
a seam in the seat surface area ma rked "AIR­
BAG". It expands between the side trim panel
and the passenger. In orde r to help provide
th is add it io na l prote ction, the side airbag
mus t inflate within a fraction of a second a t
very h igh speed and with great force. The sup­
plementa l side air bag could injure you if your
seating pos ition is not proper or up right o r if
items are located in the area where the sup­
plemental side airbag expands. This applies
especially to children
