-In certain driving situations, the safety be lts
may tighten with a reversib le tensioning
function

- The safety belts may also tighten with this
revers ible tensioning f unction in m inor colli­
s ions.
Pyrotechnic safety belt preten sioner s
The sa fety belts are equipped with safety be lt
pretensioners. The system is activated by sen­
sors in front, side and rear-end collisions of
great severity and in a rollover. Th is tightens
the belt and takes up be lt slack
c:> &. in Service
and disposal of safety belt pretensioner on
page 138 .
Taking up the slack helps to reduce
forward occupant movement during a co lli­
sion.
,& WARNING
- It is possib le for the pretensioners to de­
ploy incorrect ly .
- T he py rotechnic system can only pr ovide
pro te ction for one co llision.
If t he pyro­
technic p retensioners dep loy, the p reten ­
sioning system must be replaced .
@ Tips
The pyrotechnic safety belt p retens ioners
can only deploy once .
- The safety belt pretens ione rs do no t de­
ploy in mino r frontal and side col lisions,
i n rear -end collisions, in rollove rs and in
collisions invo lving very litt le impact
force.
- A f ine d ust is released when the pyro ­
technic safety belt pretensioners deploy.
This is normal and is not caused by a fire
i n the veh icle.
- The relevant safety requirements must
be observed when the vehicle or compo­
nents of the system are scrapped. A
qualified dea lership is familiar with
these regulations and w ill be pleased to
pass on the informat io n to you . - Be sure to observe all safety, env
iron ­
menta l and other regu lations if the ve hi­
cle or individual parts of the system, par­
ticu larly the safety belt or airbag, are to
be disposed. We recommend you have
your authorized Audi dealer perform this service fo r you.
Service and disposal of safety belt
pretensioner
T he safety belt pretens ioners are parts o f the
safety belts on your Audi . Insta lling, remov­
ing, servicing or repairing of be lt pretension­
ers can damage the safety belt system and
prevent it from working correctly in a co lli­
s ion.
There are some important t hings you have to
know to make sure that the effectiveness of
the system w ill not be impaired and that dis­
carded components do no t cause injury or pol­
l u te the environment .
A WARNING
-Improper care, serv ic ing and repair p roce-
du res can increase the risk of pe rsonal in­
j u ry and death by prevent ing a safety belt
p retensioner from activ ating w hen neede d
or activa ting it unexpectedly:
- T he belt pretensione r system can be a ct i­
vated only once. If be lt pretensioners
have been activated , the system m ust be
replaced .
- Never repair, adjus t, or change any parts
of the safety be lt system .
- Safety belt systems incl uding safety belt
pretensioners cannot be repaired. Spe ­
cial procedures are required for removal,
installation and disposa l of th is system.
- For any wo rk on the safety belt system,
we strongly recommend t hat you see
your author ized Audi dealer or qualif ied
technician who has an Audi approved re­ pa ir manua l, train ing and special equ ip­
ment necessary.

Since the circumstances will vary considerably
between on e collision and another , it is not
possible to define a range of veh icle speeds
that will cover every possible k ind and angle
of impact that will always trigger the a irbags .
Important factors include, for example, the nature (hard or soft) of the object which the
car h its, the ang le of impact, vehicle speed ,
etc. The front airbags will a lso not inflate in
side or rear collisions, or in ro ll-overs .
Alwa ys re memb er: Airbags will deploy only
once, and only in certa in kinds of collisions.
Your safety belts are always there to offe r pro­
tection in those s ituations in which airbags
are not supposed to deploy , or when they have
already deployed ; for example , when your ve­
hicle strikes or is struck by another vehicle af­
ter the first collision .
This is just one of the reasons why an a irbag is
a supp lementary restraint and is not a s ubsti ­
tute for a safety belt. The airbag system
works most effectively when used with the
safety belts. Therefore, always properly wear
your safety belts
c::;,page 131.
A WARNING
Sitting too close to the steer ing wheel or
instrument panel will decrease the effec­
tiveness of the airbags and will inc rease
the risk of pe rsonal injury in a co llision.
- Never sit closer than 10 inches (2S cm)
to the stee ring wheel or instrument pan­
el.
- If you cannot sit mo re than 10 inches
( 2 5 cm) from the steer ing whee l, investi­
ga te whethe r adaptive equipment may
be available to help you reach the pedals
and increase your seating distance from
the steering wheel.
- All vehicle occupants and especia lly chil ­
dren must be restrained properly when­
ever riding in a vehicle . An unrestra ined
or improperly restrained child could be
injured by striking the inter ior or by be­
ing ejected from the vehicle during a
sudden maneuver or impact . An unre­
strained or improperly rest rained child is
A irbag system 141
also at greater risk of injury or death
through contact with an inflating airbag .
- If you are unrestrained, leaning forward,
sitt ing s ideways or out of position in any
way, your risk of injury is much higher.
- You will a lso receive se rious injuries and
could even be killed if you are up aga inst
the airbag or too close to it when it in­
flates -even w ith an Advanced A irbag.
- To reduce the risk of injury when an air­
bag inflates, always wear safety belts
properly
c::;, page 134, Safety belts .
-Always make certain that ch ildren age 12
or younger always ride in the rear seat. If
children are not properly restrained , they
may be severe ly inju red or killed when an
airbag inf lates.
- Never let ch ildren ride unrestra ined o r
improperly restrained in the vehicle . Ad­
just the front sea ts properly.
- Never ride with the backrest reclined .
- Always sit as far as possible from the
steer ing whee l or the instrument panel
c::;, page 12 2 .
- Always sit upright with your back against
the backrest of yo ur seat.
- Never p lace your feet on the instrument
panel or on the seat . Always keep both
feet on the floor in front of the seat to he lp prevent serious inju ries to the legs
and h ips if the airbag inflates.
- Never recline the front passenger's sea t
to transport objects. Items can a lso
move into the area of the s ide a irbag or
the front airbag during braking or in a sudden maneuve r. Objects near the air­
bags can become projectiles and cause
injury when an airbag inflates.
A WARNING
A irbags that have deployed in a crash must
be replaced.
- Use on ly orig inal equipment airbags ap­
proved by Audi and installed by a trained
technician who has the necessary too ls

Child restraints on the front seat - some
important things to know
~ Be sure to read the important informat ion
and heed the WARNINGS for important de­
ta ils about ch ild ren and Advanced Airbags
Qpage 166.
Even though your vehicle is equ ipped 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
restrained for their age and size . The airbag
on the passenger side makes the front seat a potentially dangerous place for a child to ride.
The front seat is not the safest place for a
child in a forward-facing child seat. It can be a
ve ry dangerous place for an infant or a ch ild in
a rearward-facing seat.
The Advanced Airbag System in your veh icle
has been certified to comply with the require­
ments of United States Federal Motor Veh icle
Safety Standard 208 as applicable at the time
your ve hicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be turned off ("sup ­
p ressed") if a ch ild up to about one year of
age restra ined in one of the rear-facing o r fo r­
ward-facing infan t restra ints listed in Federal
M otor Vehicle Safety Standard 208 with w hich
the Advanced A irbag System in your vehicle
was certified has been installed on the front
passenger seat. Fo r a listing of the child re­
straints that were used to certify compliance

The PASSENGER AIR BAG OFF light in the in­
strument panel te lls you when the front Ad­
vanced Airbag on the passenger side has been turned off by the e lectronic control unit. E
ach time you switch on the ignition, the
PAS­
SENGER AIR BAG O FF
light will come on for a
few seconds and :
- w ill stay on if the front passenge r seat is not
occupied,
- w ill stay on if the e lec trica l ca pa citance
meas ured by the capacitive passenger de ­
tection system for the front passenger seat equa ls the combined capacitance of an in ­
fant up to about one year of age and one of
the rearward-facing or forward-fac ing ch ild
restraints listed in Federal Motor Vehicle
Safety Standard 208 with wh ich the Ad ­
vanced Airbag System in your vehicle was
cert ified . For a listing of the chi ld restraints
tha t were used to certify you r vehi cle's com­
p lia nce w it h t he U.S. Safety Standard
Q page 168.
-w ill stay on i f there is a small ch ild or child
restraint on the front passenge r seat,
- will go off if the front passenger seat is oc ­
cupied by an adult as registered by the ca ­
pacitive passenger de tection system
c::> page 152, Monitoring the Advanced Air·
bag System.
The PASSENGER AIR BAG OFF light comes on
when e lectrica l capacitance registered on the
front passenger seat is eq ua l to or less tha n
the comb ined capacitance of a typica l 1 year­
o ld infant and one of the rearward-facing or
forward-facing chi ld restraints listed in Feder­
al Motor Vehicle Safety Standard 208 with
wh ich the Advanced Airbag System in your ve­
hicle was certified.
If the total electr ica l capacitance registered
on the front passenger seat is more than that
of a typical 1 year -o ld child but less than the
weight of a small adult , the front airbag on
t h e passenger side can deploy (the
PASSEN­
GER AIR BAG OFF
light does not come on).
If the
PASSENGER AIR BAG OFF light does
not come on, the front airbag on the passen­
ger side has not been turned off by t he e lec­
t ro ni c cont ro l unit and can deploy if the con­
t ro l uni t se nses an impact tha t mee ts the con-
di tions stored in its memory .
1J1>

Fo r exa mple, the a irbag may depl oy if:
-a small child that is heavier than a typical 1
year-o ld child is on the front passe nger seat
(regardless of whether the child is in one of
the chi ld seats listed
page 168), or
- a ch ild who has outgrown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
P ASS ENGER AIR B AG OFF light comes on in
the instrument cluster and stays on.
If the front passenger airbag deploys, the
Federal Standard requires the airbag to meet
the "low risk" deployment criter ia to reduce
the r isk of injury through interaction with the
airbag. "Low risk" deployment occurs in those
crashes that take place at lower decelerations
as defined in the electronic control unit
r::> page 153, PASSENGER AIR BAG OFF light.
Always remember, a chi ld seat or infant carri­
er insta lled on the front seat may be struck
and knocked out of position by the rapidly in­
flating passenger's airbag in a frontal colli­
sion. The airbag could greatly reduce the ef­
fectiveness of the child restraint and even se­
riously injure the child during inflat ion.
For this reason, and because the back seat is
the safest place for children - when properly
restrained according to their age and size - we
strongly recommend that children always sit
in the back seat
r::> page 166, Child Safety .
A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be
ser iously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System .
- T he inflating airbag will hit the child seat
or infant carrier with great force and wi ll
smash the child seat and child against
the backrest, center armrest, door or roof.
- Always install rear-facing child seats on
the rear seat.
- If you must install a rearward facing
child seat on the front passenger seat
-
A irbag system 143
because of exceptional circumstances
and the
PAS SENGER AIR BAG OFF light
does not come on and stay on, immed i­
ately install the rear-fac ing child seat in a
rear seat ing pos ition and have the airbag
system inspected by your A udi dealer.
- Forward-facing child seats installed on the front passenger's seat may interfere
with the dep loyment of the a irbag and
cause serious persona l injury to the
child.
A WARNING
If, in except iona l circumstances, you must
install a forward -facing child restraint on
the front passenger's seat:
- Always ma ke s ure the forward-facing
seat has been designed and certified by its manufacturer for use on a front seat
with a passenger front and s ide a irbag.
- Never put the forward-facing child re­
straint up against or very near the instru ­
ment panel.
- Always move the passenge r seat into its
rea rmost pos ition in the seat's fore and
aft ad justment range, as far away from
the airbag as possible before installing
the forward-fac ing ch ild restra int. The
backrest must be adjusted to an upright
position.
- Make sure that the
PASSENGER AIR BAG
OFF
l ight comes on and stays on all the
time wheneve r the ig nit ion is switched
on.
A WARNING
To reduce the ri sk of ser ious injury, ma ke
sure that the
PASSENGER AIR BAG OFF
light w ill be displayed whenever a child re ­
straint is insta lled on the front passenger
seat and the ignition is switched on.
- If the PASSENGER AIR BAG OF F light
does not stay on, perform the checks de­
scribed

light does not stay on .
- Have the airbag system inspected by
your Audi dealer immed iately.
- Always carefully follow instructions from
child restraint manufacturers when in­
sta lling child restraints .
A WARNING ,.
If, in exceptional c ircumstances, you must
install a forward or rearward-fac ing child
restraint on the front passenge r's seat:
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
t ion.
- An improperly installed child restraint
can interfere with the airbag as it de ­
ploys and serio usly injure or even kill the
child -even wi th an Advanced Airbag
System.
- Always carefully follow the manufactur­
er's instructions provided with the child
seat or car rier .
- Always m ake su re 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 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 pe rson actually s itting on the
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 ai rbag 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 . 122 Loc atio n of drive r air b a g : i n stee ring wheel
Fig. 123 Loc ation of fro nt passe nge r's a irbag: in the in ­
str umen t pa nel
Your vehicle is equipped with an "Advanced
Airbag System " in compliance with Un ited
States Federa l Motor Veh icle Safety Standard
(FMVSS) 208 as applicable at the time you r
vehicle was manufactured . The safety belts
for the seats have "pretensioners" that help to take slack out of the belt system. The pre­
ten sioners are also act ivated by the electronic
control unit for the airbag system.
T he front safety belts also have load lim iters
to help reduce the forces applied to the body
in a crash.
The airbag for the driver is in the steering
whee l hub
c:> fig. 122 and the airbag fo r the
front pas senger is in the instr ument panel
c::;, fig . 123. The gener al location of the a irbags
is marked "AIRBAG".
T here is a lot you need to know about the a ir­
bags in your vehicle. We urge you to read the
II>

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 ex tremely 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
deploys and cause serious personal in­
jury.
- Never hold things in your hands or on
your lap when the vehicle is in use .
-
Airbag system 145
-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.
A 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.
- The Advanced Airbag System can deploy
in accordance with the ,,low risk" option
for 3-and 6-year-old children under the
•
•
•

of a typical 1 year-old, but less than the
weight of a small adult, the front airbag on
the passenger s ide may deploy (the
P A SSEN·
GER AIR BA G OFF
light does not come on).
For example, the a irbag may depl oy if:
- a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld seats listed
page 168),
-a ch ild who has outgrown child rest raints is
on the front passenger seat.
I f the front passenger airbag is turned off, the
PA SSENGER AIR BAG OFF light in the center
of the inst rument panel w ill come on and stay
on.
If the front passenger airbag deploys, the
Federal Standard requires the a irbag to meet
the " low ris k" deployment criteria to help re ­
d uce the risk of injury through interaction
with the airbag . "Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the electronic control
un it
r:::> page 152.
Alw ays remember : Even though your vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat. Please be sure to read the impor­
tant information in the sect ions that follow
and be sure to heed all of the WARNINGS .
A WARNING
To reduce the risk of injury when an airbag
inflates, always wear safety belts prope rly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of injury is much higher.
- You w ill also receive serious injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in­
fla tes - even with an Advanced Airbag
page 140 .
A WARNING ,~
A child in a rearward -facing child seat in -
stalled on the front passenger seat will be
-
A irbag system 147
seriously injured and can be killed if the
front airbag inflates - even w ith an Ad­
vanced A irbag System.
- Altho ugh the Advanced Airbag System in
your veh icle is designed to turn off the
front airbag when a rearward-facing child restraint has been installed on the
front passenge r seat, nobody can abso­
lutely guarantee that dep loyment is im­
possible in all conceivable s ituations that
may happen dur ing the usefu l life of your
veh icle.
- The infla ting airbag will h it the ch ild seat
or infant carrier with g reat force and will
smash the child seat and child against
the backrest, center armrest, door, or
roof.
- Always install rearward-facing chi ld re­
straints on the rear seat.
- If you must install a rearward fac ing
child seat on the front passenger seat because of exceptional circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immed i·
ately insta ll the rear-fac ing child seat in a
rea r seat ing pos ition and have the airbag
system inspected by you r Audi dealer .
A WARNING
If, in except iona l circumstances, you must
install a forward-facing child restraint on
the front passenge r's seat:
- Always ma ke sure the forward-facing
seat has been designed and cer tified by
its manufacture r for use on a front se at
with a passenger fron t and s ide a irbag .
- Never put the fo rward-facing child re­
straint up against or ve ry near the instru­
ment panel.
- Always move the passenge r seat into its
rea rmost pos ition in the seat's fore and
aft ad justment range, as fa r away from
the airbag as possible, before installing
the forward-fac ing chi ld restraint. The
backrest must be adjusted to an upright
position .

148 Airbag system
-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 would have worked without the object on the
seat.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
lot of very important parts of the Advanced
Airbag System in it. These parts include the
capacitive passenger detection system, wir­
ing, brackets, 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
malfunction in the one of the system compo­
nents is detected
¢ page 153. Because the
front passenger seat contains important parts
of the Advanced Airbag System, you must
take care to prevent it from being damaged.
Damage to the seat may prevent the Ad­
vanced Airbag System for the front passenger
seat from doing its job in a crash.
The front Advanced Airbag System
consists of the following:
- Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration
to provide information to the Advanced Air­ bag System about the severity of the crash .
- An electronic control unit, with integrated
crash sensors for front and side impacts.
The control unit "decides" whether to fire the front
airbags based on the information
received from the crash sensors. The control
unit also "decides" whether the safety belt
pretensioners should be activated.
- An Advanced Airbag with gas generator for
the driver inside the steering wheel hub.
- An Advanced Airbag with gas generator in­
side the instrument panel for the front pas­
senger.
- A capacitive passenger detection system un­
derneath the front passenger seat cover.
This system measures the electrical capaci­ tance of the person in the seat. The informa­
tion registered is sent continuously to the
electronic control unit to regulate deploy­ ment of the front Advanced Airbag on the
passenger side.
- An airbag monitoring system and indicator
light in the instrument cluster
¢page 152 .
-A sensor in each front seat registers the dis­
tance between the respective seat and the steering wheel or instrument panel. The in­
formation registered is sent continuously to
the electronic control unit to regulate de­
ployment of the front Adv a need Airbags.
- The
PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instru­
ment panel
¢ page 210 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 driv­
er 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
prevent the front airbag from working
properly.
- Improper repair or disassembly of the
front passenger and driver seat will pre­
vent 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 seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or put them on the seat. The capacitive passenger detection mat in the front
passenger seat will not function properly
if it is punctured .
- Never carry things on your lap or carry
objects on the front passenger seat.
Such objects can influence the capaci­
tance registered by the capacitive pas­ senger detection system, so that incor­
rect information is provided to the airbag
control unit.
- Never store items under the front pas­
senger seat. Parts of the Advanced Air­
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper­
ly.
- Never place seat covers or replacement
upholstery that have not been specifical­
ly approved by Audi 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 deploying prop­
erly .
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys­
tem 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 capaci­
tance of the child safety seat and/or the
person on the seat and thus keep the Ad­
vanced Airbag System from working properly.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
Airbag system 149
games device, power inverter or seat
heater for child seats) on the front pas­
senger seat if the device is connected to
the 12-volt socket or the cigarette light­
er socket. Such devices can influence the
capacitance registered by the capacitive passenger detection system, so that in­
correct information is provided to the air­
bag control unit.
- If you must use a child restraint on the
front passenger seat and the child re­
straint manufacturer's instructions re­
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re­
straint is installed on the front passen­
ger seat.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install child restraint in a rear seat­
ing position and have the airbag system
inspected by your Audi dealer.
.&_ WARNING
If the front passenger seat gets wet, dry it
immediately.
- If liquid soaks into the front passenger
seat, this can keep the airbag system
from working properly and may, for in­
stance, deactivate the passenger frontal
airbag. If this happens, the
PASSENGER
AIR BAG OFF
light will come on and stay
on together with the airbag indicator light
fl in the instrument cluster.
- If liquid is pooled on the seat, but has
not soaked in, this may also keep the air­
bag system from working properly and
cause the passenger frontal airbag to be
enabled (turned on), even though there is a properly installed child restraint sys­
tem on the seat . Wet towels or other wet
things on the seat cushion can have the
same effect. If the front passenger fron­
tal airbag is turned on, the
PASSENGER
AIR BAG OFF
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 saf ety be lts
with pretensioners and load limiters and the
adjus table head restr aints* to help reduce the
risk of injury in a wide range of acc ident and
crash situat ions. Be sure to read the impor­
tant information about safety and heed the
WARNINGS in this chapter .
Deployment of the Advanced Airbag System
and the activat ion of the safety belt preten­
sioners depend on the decelerat ion measured
by the crash senso rs and regis tered by the
e lectronic control u nit. Crash sever ity depends
on speed and deceleration as well as the mass
and stiffness of the vehicle or object involved
in the crash.
On the passenger side, regard less of safety
be lt use, the front passenger fronta l airbag
will be turned off i f the e lectrical capac itance
measured by the capacitive passenger detec­
tion system on the front passenge r seat is less
than the amount programmed in the electron­ ic control unit. The front passenger frontal air­
bag will also be turned off if the capacitance
measured by the system for the front passen­
ge r seat equa ls that of an infant of abo ut one
yea r of age i n one of the child sea ts that was
used to cer tify the Advanced Airbag System
under Federal Motor Vehicle Safety Standard
208 . The
PASSENGER AIR BAG OF F light
comes on and stays on to tell you when the
front Advanced A irbag System on the passen­
ger s ide has been turned off¢

A WARNING
To reduce the risk of injury when a n airbag
inflates, a lways wear safety belts properly .
- If you are unrestrained, leaning forward,
sitting sideways or out of position in any
way, your risk of inj ury is much higher.
- You wi ll also receive serious injuries and
could even be killed if you are up against
the a irbag or too close to it when it in- flates
-even w ith an Advanced A irbag

Safety be lts are important to he lp keep front
seat occupants in the proper seated position
so that a irbags can unfold proper ly and pro­
vide supplemental protect ion in a frontal col­
lis ion .
The front airbags are designed to provide ad­ ditional protection for the chest and face of
the driver and the front seat passenger when :
- safety belts are worn proper ly,
- the seats have been positioned so that the
occupant is properly seated as far as poss i­
b le from the airbag ,
- and for ad justab le head restraints : the head
restraints have been properly adj usted .
Bec ause airbags inflate in the bli nk of an eye
with great force, th ings you have on your lap
or have p laced on the seat co uld become dan ­
gerous pro jecti les, and be p ushed into you if
the a irbag inf lates .
When an airbag deploys, fine dust is re leased.
T his is no rma l and is not caused by a fi re in
the vehicle . This dust is made up mostly of a
powder used to lubricate the airbags as they
deploy . It could irr itate skin .
It is important to remembe r that while the
supplementa l airbag system is designed to re­
duce the like lihood of serious injur ies, other
injur ies, for examp le swelling, bruising and
minor abrasions, can also happen when air-
bags inflate . A irbags do not protect the arms
