160 Safety belts
_& WARNING
Never unfasten safety belt while the veh i
cle is moving . Doing so will increase your
r isk of being injured or killed.
Improperly worn safety belts
Incorrectly positioned safety belts can cause
severe injuries.
Wear ing safety belts improperly can cause se
rious in jury or death. Safety belts can only
work when they are correct ly positioned on
the body. Improper seating positions reduce
the effect iveness of safety belts and will even
increase the risk of injury and death by mov
ing the safety belt to critical areas of the
body. Improper seating positions also in
crease the risk of serious injury and death
when an airbag deploys and str ikes an occu
pant who is not in the correct seating posi
tion . A driver is responsib le for the safety of
a ll vehicle occupants and especially for chi l
dren. Therefore:
• Never permit anyone to assume an incorrect
s itting position in the veh icle wh ile traveling
Q 8_ .
_& WARNING
Improperly worn safety belts increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- Always make sure that all vehicle occu-
pants are correct ly restrained and stay in
a correct seating position whenever the
vehicle is be ing used.
- Always read and heed all WARNINGS and
other important information

Safety belt preten
sioners
How safety belt pretensioners work
In front, side and rear-end collisions above a
particular severity, safety belts are tensioned
automatically.
T he safety belts are equipped with safety belt
pretensioners. The system is activated by sen
sors in front, side and rear-end collisions of
great severity. This tightens the belt and takes
up belt slack
Q & in Service and disposal of
safety belt pretensioner on page 161.
Taking
up the slack helps to reduce forward occupant
movement during a collision.
([) Note
Never let the belt remain over a rear seat
back that has been fo lded forward.
(D Tips
The safety belt pretensioner can only be
activated once.
-In minor frontal and side collisions, in
rear-end collisions, in a rollover and in
accidents involving very little impact
force, the safety belt pretensioner are
not activated .
- In the case of a side crash, the safety
belt pretensioners will activate on the
driver's or front passenger's sides only,
depending on which side of the veh icle
the crash occurs.
- When the safety belt pretensioners are
act ivated, a fine dust is released. This is
normal and is not caused by a fire in the
vehicle.
- The relevant safety requ irements must
be observed when the vehicle or compo
nents of the system are scrapped. An au
thorized Audi dealer or qualified work
shop is familiar with these regulations
and wi ll be pleased to pass on the infor
mation to you.

Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job , occupants must al
ways properly wear their safety belts and be
in a proper seating position.
F or your safety and the safety of your passen
gers, before driving off, a lways:
• Adjust the dr iver's seat and steering wheel
properly ¢
page 145,
• Adjust the front passenger's seat properly
¢page 62,
• Wear safety be lts properly ¢ page 15 7,
• Always properly use the proper child re-
stra int to protect children¢
page 186.
In a collision airbags must inflate within the
blink of an eye and with considerable force .
The supplementa l airbags can cause injuries if
the dr iver or the front seat passenger is not
seated properly . Therefore in order to he lp the
a irbag to do its job, it is important, both as a
d river and as a passenge r to sit properly at all
times.
By keeping room between your body and the
steering wheel and the front of the passenger
compartment, the airbag ca n inflate fully and
comp letely and provide supp lemental p rotec
tion in ce rtain frontal collisions¢

It's especially important that children a re
properly restrained ¢
page 186.
There is a lot that the driver and the passen
gers can and must do to help the individua l
safety features ins talled in your A udi work to
gether as a system.
Prope r seat ing pos ition is important so that
the front airbag on the driver s ide can do i ts
job. If yo u have a physical impa irment or con- dition that prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the peda ls , spec ial
modifications to your vehicle may be necessa
ry.
Contact your a uthorized Audi dea ler, or call
Audi C ustomer Re lations at 1-800-822-2834 .
When the airbag system dep loys, a gas gener
ator will f ill the ai rbags, break open the pad
ded covers, and inf late between the steering
whee l and the dr iver and between the instru
ment pane l and the front passenger. The air
bags will deflate immediately after dep loy
ment so that the front occupants can see
th rough the w indshield aga in without inter
ruption .
All of th is take s place in the blink of an eye, so
fast that many people don't even realize that
the a irbags have dep loyed . The airbags also
inflate with a g reat dea l of force and nothing
shou ld be in their way when they deploy.
F ront a irbags in combination with properly
worn safety bel ts slow down and lim it the oc
c u pant's forward movement. Together they
help to prevent the drive r and front seat pas
senger from hitting parts of the inside the ve
hicle while reducing the forces acting on the
occupant dur ing the crash. In this way they
help to reduce the risk of injury to the head
and uppe r body i n the c rash . A irbags do not
protect the a rms or the lower parts of the
body.
Both front a irbags w ill not i nflate in all fronta l
collisions . The t rigge ring of the a irbag system
depends on the vehicle dece lerat ion rate
c aused by the co llision and reg istered by the
elect ron ic cont ro l u nit. If t his rate is below
the re ference value programmed into the con
trol unit, the airbags will not be trigge red ,
even though the car may be bad ly damaged as
a res ult of the collision . Veh icle damage, re
pair costs or even the lack of veh icle damage
is no t necessarily an indication of whether an
airbag should inflate or not .
It is not possib le to define a range of vehicle
speeds that w ill cover every possib le kind and .,.
164 Airbag sys te m
Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
all c hildren, especially those 12 years and
younger, a lways ride in the back seat properly
restra ined for their age and size. The airbag
on the passenger side makes the front seat a potentially dangerous place for a ch ild to r ide.
The front seat is not the safest place for a
child in a fo rward-facing ch ild safety seat. It
can be a very dangerous place for an infant or
a child in a rearward-facing seat.
The Advanced Airbag System in your veh icle
has been certified to comp ly with the Requ ire
ments of United States Federa l Mo tor Veh icle
Safety Standard 208 as applicable at the time
your vehicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be turned off ("sup
pressed") if a ch ild up to about one year of
age restrained in one of the rear -facing or for
ward -facing infant restraints listed in Federal
Motor Vehicle Safety Standard 208 with which
the Advanced A irbag System in your vehicle
was certified has been installed on the front passenger seat . For a listing of the child re
strai nts that we re used to certify compliance
with the US Safety Standard

The PASSENGE R AIR BAG OFF light in the in
strument panel te lls you when the front Ad
vanced A irbag on the passenger side has been
turned off by the e lectronic control unit.
Each t ime you turn on the ignition, the
PAS
SENGER AIR BA G OFF
light will come on for a
few seconds and:
- will stay on if the front passenger seat is not
occupied,
- wi ll stay on if there is a small child or child
restraint on the front passenger seat,
- wi ll go off if the front passenger seat is oc
cupied by an adult as registered by the
weight-sensing mat
r=v page 173, Monitor
ing the Advanced Airbag System .
The PASSENGE R AIR BAG OFF light comes on
when the control un it detects a total weight
on the front passenger seat that requires the
front airbag to be turned off.
If the total weight on the front passenge r
seat is more than that of a typica l 1 year -old
chi ld but less than the weight of a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
li ght does not come on). If the PAS SENGER
AI R BAG OFF
light does not come on, the
front a irbag on the passenger side has not
been tu rned off by the elect ronic con trol unit
and can deploy if the control unit se nses an
impact that meets the cond itions stored in its
memory .
For exampl e, th e airbag ma y deploy if:
-a small ch ild that is heav ier than a typical 1
year-old ch ild is on the front passenger seat
( r egard less of whether the child is in one of
t he child safety seats listed
r=v page 188), or
- a child who has outgrown ch ild restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instrument cluster and stays on.
The front airbag on the passenger s ide may
not deploy (the PASSENGER AIR BAG OFF
light does not illum inate and stay lit) even if a
small adult or teenager, or a passenger who is
not sitt ing up rig ht w ith their back against a
non- recl ined ba ck res t w it h thei r feet on the
vehicle floor in front of the sea t is on the front
passenger seat
r=v page 145, Proper seating
position for the driver.
If the front passenger a irbag dep loys, the
F ede ra l Standard req uires the airbag to meet
the "low risk" dep loyment criteria to reduce
the risk of injury t hro ugh interaction wit h the
airbag. "Low risk" dep loyment occ urs in those
crashes that take place at lower dece lerat ions
as defined in the electronic control unit
r=v page 173, PASSENGER AIRBAG OFF light.
Always remember, a ch ild safety seat or infant
carr ier installed on the front seat may be
struck and knocked out of posit ion by the rap
idly inflat ing passenger's airbag in a fronta l
collision . T he a irbag could greatly reduce the
effectiveness of the ch ild restraint and even
seriously injure t he ch ild during inflation .

tered by the weight-sensing mat and can
cause injury in a crash.
Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants.
F ig . 175 Location of driver airbag: in steer ing whee l
Fig. 176 Location of front passenger's airbag: in the in
strument panel
Your veh icle is equipped with an "Advanced
A irbag System" in compliance with United
States Federal Motor Vehicle Safety Standard ( FM VSS) 208 as app licab le at the time your
ve hicl e was manufac tured. The system senses
the position of the front seats and controls
front airbag inflation with a valve, depending
on the distance between the respect ive seat
and the steering wheel or instrument panel.
The safety belts for the seats have "preten
sioners" that he lp to take slack out of the belt
system . The pretensioners a re also activated
by the electron ic cont ro l unit for the ai rbag
system. T
he front safety belts also have load limiters
to help reduce the forces applied to the body
i n a crash .
T he airbag for the drive r is in the stee ring
whee l hub¢
fig. 175 and the airbag for the
front passenger is in the instrument panel
~ fig. 176. The general locat ion of the a irbags
is marked "AIRBAG".
T here is a lot you need to know about the ai r
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 th e owner's literature.
P lease be sure to heed the WARNINGS -they
are extremely importa nt for your safety and
the safety of your passengers, especially in
fants and small chi ldren.
_&. WARNING
Neve r rely on airbags alone for p rotection.
- Even w hen they deploy, airbags provide
only s upplement al pro te ctio n.
- Airbag work most effect ive ly when used
with p roperly wor n safety bel ts.
- Therefore, always wea r you r safety belts
a nd make sure tha t eve rybody in your ve
h icle is properly res trained.
_&. WARNING
A pe rson on the front passenger seat, es
pe cial ly infa nts and sm all ch ildren, w ill re
ceive serio us inju ries and can even be kil

it inflates .
- Although t he Advanced Airbag System in
your veh icle is designed to tur n off the
front passenger airbag if an infant or a
small child is on the front passe nger
seat, nobody can absolutely guarantee
that deployment under these special
conditions is imposs ible in all conceiva
b le sit uat ions that may happen dur ing
the useful life of your vehicle.
- The Advanced Airbag System can dep loy

old child is on the front passenger seat
and the other conditions for airbag de
ployment 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 ai rbag 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.
T he 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
Airbag system 167
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 ¢
page 188 , Child restraints and
Advanced Airbags .
"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
¢page 188,
-weight less than a threshold level stored in
the control unit is detected on the front pas
senger seat.
When a person is detected on the front pas
senger seat, weighing more than the total
weight of a child that is about 1 year old re
strained in one of the rear-facing or forward
facing infant restraints (listed in Federal Mo
tor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified), the front airbag on the passen ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to
tal weight on the front passenger seat that re
quires 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 conditions stored in
its memory.
If the total weight 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). ..,. •
•
-Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before installing
the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime w henever the ignition is sw itched
on.
Advanced Airbag System components
The fron t passenger seat in your vehicle has a
lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sensing mat, sensors, wiring, brack
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on .
The control un it mon itors the Advanced Air
bag System and turns the airbag indicator
l ight on whe n a ma lfunction in t he sys tem
components is de tected. The function of the
airbag indicator light is described in greater
detai l below . Because the front passenger
seat contains important parts of the Ad
vanced A irbag System, you m ust take care to
prevent it from being damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/decele ration
to provide information to the Advanced Air
bag System about the seve rity of the crash.
- An electronic co ntrol unit, with integrated
c rash se nsors for front and side impacts .
T he cont ro l unit " decides " whethe r to fire
the front airbags based on the inform ation
received from the crash senso rs . The contro l
unit a lso "decides" whether the safety belt
pretensioners should be activated .

-Improper repair or disassembly of the
front passenger and driver seat will pre
vent the Advanced A irbag 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
dr iver seat from the veh icle .
- Never remove the upholstery 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 place them on the seat. If the weight
sensing mat in the passenger seat is punctured it cannot work properly.
- Never carry things on your lap or carry
objects on the passenger seat. Such
items can increase the weight registered
by the weight-sens ing mat and send the
wrong info rmation to the airbag control
unit.
- Never store items under the front pas·
senger seat. Parts of the Advanced Ai r
bag System under the passenge r seat
cou ld be damaged, prevent ing them and
the airbag system from wo rking proper
ly .
- Never place seat covers or replacement upholstery that have not been specifical
ly approved by A udi on the front seats.
- Seat covers can prevent the Advanced Airbag System from recognizing child re
straints or occupants on the front pas
senger seat and prevent the side airbag in the seat backrest from deploy ing prop
erly.
- Never use cush ions, pillows, blankets or
similar items on the front passenger
seat. The add itiona l padd ing will prevent
the weight-sensing mat in the seat from
accu rately reg iste ring the c hild restra int
or person on the seat and prevent the

-If you must use a child restra int on the
front passenger seat and the ch ild re- straint manufacturer's instructions
re
qu ire the use of a towel, foam cushion or
something e lse to properly pos ition the
child restraint, make certain that the

How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide airbags supp lement the protection of
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help redu ce the
risk of inju ry in a wide range of accident and
c rash situations. Be s ure to read the impor
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need A irbag System
and the activation of the safety belt preten
sioners depend on the deceleration measured
by the crash sensors and registered by the
electron ic control unit. The amount of infla
tion of the front airbags can a lso be adapted
to the front seat pos ition, depending on the
distance between the respect ive front seat
and the steer ing w heel or instrument panel as
registered by sensors in the seats. Crash se·
verity depends on speed and deceleration as
well as the mass and st iffness of the vehicle
o r object involved in the crash .
On the passenger side, regardless of safety
belt use, the ai rbag w ill be tu rned off if the
we ight on the passenger seat is less than the
amount programmed in the e lectronic control
u nit. The front airbag on the passenger side
will a lso be turned off if one of the child safe -
ty seats that has been certified under Federal Motor Vehicle Safety Standard 208 has been
recogni zed on the seat . The
PAS SENGER AIR .,..
172 Airbag system
must always sit in an upright position,
must not lean against or place any part
of their body too close to the area where
the airbags are located .
- Occupants who are unbelted, out of posi
tion or too close to the airbag can be se riously injured by an airbag as it unfolds
with great force in the blink of an eye
~page 163.
A WARNING
A child in a rearward-facing child safety
seat installed on the front passenger seat
will be seriously injured and can be killed if
the front airbag inflates -even with an Ad
vanced 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 facing
child safety seat on the front passenger
seat because of exceptional circumstan
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer.
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
or by being pushed into you as the airbag
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 air
bags during braking or other sudden ma
neuver and become dangerous projec- tiles that can cause serious personal in
jury if the airbags inflate.
- Never place or attach accessories or oth
er objects (such as cupholders, tele phone brackets, large, heavy or bulky ob
jects) on the doors, over or near the area marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be
tween those areas and yourself. These
objects could cause injury in a crash, es
pecially 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 airbag during braking or in a
sudden maneuver. Objects near the air
bags can become projectiles and cause
injury, particularly when the seat is re
clined.
A WARNING
'-
The fine dust created when airbags deploy
can cause breathing problems for people
with a history of asthma or other breath
ing conditions.
- To reduce the risk of breathing problems, those with asthma or other respiratory
conditions should get fresh air right
away by getting out of the vehicle or
opening windows or doors.
- If you are in a collision in which airbags
deploy, wash your hands and face with
mild soap and water before eating.
- Be careful not to get the dust into your
eyes, or into any cuts or scratches.
- If the residue should get into your eyes,
flush them with water.
