I f the front passenger airbag dep loys, the Feder ­
al 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
in the electronic control unit.¢

Alway s remember: Even though your vehicle is
equ ipped w ith Advanced Airbags, the safest place
for children is properly restrained on the back
seat . Please be sure to read the important infor­
mat ion in the sections that follow and be sure to
heed a ll of the WARN INGS.
A WARNING
To red uce the risk of inj ury when an ai rbag in­
fla tes, a lways wear safety bel ts p roperly.
- If you are unrestrained, leaning fo rwa rd, s it­

A WARNING
A child in a rearward-facing chi ld safety seat
installed on the front passenger seat wi ll be
ser iously injured and can be killed if the front
airbag inflates - even w ith an Advanced Airbag
System.
- Although the Advanced A irbag System in
your vehicle is designed to turn off the front
airbag when a rearward-facing child re­
straint has been installed on the front pas­
senger seat, nobody can absolutely g uaran­
tee that deployment is impossible in all con­
ceivable s ituations that may happen during
the usef ul life of your vehicle .
- The inflating a irbag w il l hit the child safety
seat or infant c arrier wi th great force and

greater detail below. Because the front passen­
ger seat contains important parts of the Ad­
vanced A irbag System, you must take care to pre ­
vent 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 Ad vanced Airb ag S ystem con sis ts
of the follo wing :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/decelerat io n to
provide information to the Advanced Airbag
System about the severity of the crash .
- An electronic control unit, with integrated
crash sensors for front and side impacts . The
contro l unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit also "de ­
cides" whether the safety be lt pretensioners
shou ld be activated.
- An Advanced Airbag with gas generator and
contro l valve for the driver inside the steering
whee l hub .
- An Advanced Airbag with gas generator and
contro l valve inside the instrument pane l for
the front passenger.
- A weight -sensing mat under the upho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat . The
information registered is sent continuously to
the electron ic control unit to regulate deploy­
ment of the front Adva need A irbag on the pas­
senger side.
- An airbag monitoring system and indicator
light i n the instrument cluster
¢page 140.
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation reg istered is sent cont inuous ly to the
electronic control unit to regulate deployment
of the fro nt Adv a need A irbags.
- T he
PASS EN GE R AIR BAG OFF light comes on
and stays on in the center of the instrument
pane l¢
page 140, fig . 149 and tells you when
the front Advanced Airbag on the passenge r
side has been turned off.
- A sensor below the safety belt latch fo r the
front seat passenger to meas ure the tension on
Airb ag sys tem
the sa fety belt. The tension on the safety belt
and the weight registered by the weight-sens­
ing mat help the control unit "decide" whether
the front airbag for the front passenger seat
should be turned off or not¢
page 131, Child
restraints on the front seat -some important
things to know.
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transmits this information to t he electronic
cont rol un it.
_& WARNING
Damage to the front passenge r seat can pre­
vent the front airbag from working properly.
- Imp roper repair or disassembly of the front
passenger and driver seat will p revent the
Advanced Airbag System from f unctioning
properly.
- Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personne l.
- Never remove the front passenger or driver
seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
- Never d isassemble o r remove par ts from the
seat o r disconnect w ires from it.
- Never carry sh arp objects in your pocke ts or
p lace them on the seat. If the weight-sens­
ing mat in the passenger seat is punctu red
it cannot work proper ly.
- Never carry things on your lap or carry ob­
jects on the passenger seat. S uch items can
increase the weight reg istered by the
weight-sensing mat and send the wrong in­
formation to the airbag control unit.
- Never store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, p reventing them and the airbag sys­
tem from working p roper ly.
- Never p lace seat covers or replacement up­
holstery that have not been specifically ap­
p roved by A udi on the front seats.
- Seat covers can prevent the Advanced A ir­
bag System from recognizing chi ld
137

Airbag syste m
restraints or occupants on the front passen­
ger seat and prevent the side airbag in the
seat backrest from deploying properly.
- Never use cushions, pillows, blankets or
similar items on the front passenger seat.
The additional padding will prevent the
weight-sens ing mat in the seat from accu­
rately reg istering the ch ild restraint or per­
son on the seat and prevent the Advanced
Airbag System from funct ioning prope rly.
- If you must use a child restraint on the front
passenge r seat and the child restraint man­
ufact urer's instructions require the use of a
towel, foam cushion or something else to properly position the chi ld restraint, make
certain that the
PASSENGER A IR BAG OFF
light comes on and stays on whenever the
child restraint is installed on the front pas­
senger seat.
- If the
PAS SENGER AIR BAG O FF light does
not come on and stay on, immediately in­
stall child restraint in a rear seating position and have the airbag system inspected by
you r authorized Aud i deale r.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
ai rbags supplement the protection offered by the
front three-point safety belts with pretensioners and load limiters and the adjustable head re ­
stra ints to help reduce the r isk of injury in a wide
range of accident and crash situations. Be sure to
read the important information about safety and heed the WARNINGS in th is chapter .
Deployment of the Advanced Airbag 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 we ll as the mass and stiffness of the
vehicle or object involved in the crash.
On the passenger s ide, regardless of safety belt
use, the a irbag will be t urned off if the weight on
the passenge r seat is less than the amount p ro­
g rammed in the e lectron ic cont rol unit . T he front
1 38
airbag on the passenger side will also be turned
off if one of the child safety seats that has been
certified under Federal Motor Vehicle Safety
Standard 208 has been recogn ized on the seat.

.&_ WARNING
To reduce the risk of injury when an airbag in­
f lates, always wear safety belts properly.
- I f you are unrestrained, leaning forward, sit­
ting sideways or ou t of position in any way,
your ris k of injury is much highe r.
- You will a lso receive ser ious injuries and
could even be killed if yo u are up against the

More important things to know about front
airbags
Fig. 14 8 Inflated front a irbags
-,... N 0 :i: ;;i;
Safety be lts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfo ld properly and prov ide sup­
plemental protection in a fronta l co llision.
The front airbags a re 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,
- t he seats have been positioned so that the oc-
cupant is properly seated as far as possib le
from the airbag,
Ill-

-and the head restraints have been properly ad -
justed.
Because airbags inflate in the blink of a n eye w ith
great for ce, things you have on you r lap or have
p laced on the seat cou ld become dangerous pro ­
jectiles, and be pushed into you if the airbag in ­
flates.
When an a irbag 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 irr itate skin.
It is important to remember that while the sup­
p lemental airbag system is designed to reduce
the likelihood of ser ious injuries, other inj uries,
for example swell ing, 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 only supplement the
three po int safety belts i n some fronta l co llisions
i n which the veh icle decelerat ion is high enough
to deploy the airbags.
F ront airbags will not deploy:
- if the ignit ion is switched off when a crash oc -
curs,
- in 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
o ld needed for airbag deployment as registered
by the electronic contro l unit .
Th e front passeng er airbag will a lso not
deplo y:
- when the front passenger seat is not occupied,
- when the weight on the front passenger seat as
sensed by the Advanced Airbag System indi­
cates that the front airbag on the passenger
s ide has to be turned off by the electronic con­
trol unit (the
P A SSENGER AIR B AG OFF light
comes on and stays on).

Airb ag sys tem
-To reduce the risk of injury when the ai rbags
inflate, the driver and passengers must al­
ways sit in an upright posit ion, must not
lean aga inst or place any part of their body
too close to the area where the airbags are located.
- Occupants who are unbelted, out of posit ion
or too close to the airbag can be seriously in jur ed by an airbag as it unfolds with g reat
for ce in the blink of an eye
Qpage 131.
A WARNING
A child in a rearward-facing child safety seat
i nsta lled on the front passenger seat will be
seriously injured and can be k illed if the front
a irbag inflates - even with an Advanced Airbag
System .
- The inflating airbag will hit the child safety seat or infant ca rrier with great force and
will smash the child safety seat and child aga inst the backrest, center armrest, door
or roof.
- Always install rear-fac ing child safety seats
on the rear seat.
- If you must install a rea rwa rd facing child
safety seat on the front passenger seat be ­
cause of exceptional circumstances and the
PA SS ENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rea r-facing child safety seat in a rear
seating position and have the a irbag system
inspected by your au thori zed A udi dealer.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds or by be ­
ing p ushed into you as the airbag inflates .
- Never hold things in yo ur hands or on your
lap when the vehicle is in use .
- Never transport items on or in the area o f
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.
139

Airbag syste m
-Never place or attach accessories or other
objects (such as cupholders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked "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 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 a ir­
bag during braking or in a sudden maneu­
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined.
A WARNING
The fine dust created when airbags deploy can
cause breath ing problems for people w ith a
history of asthma or other breathing condi­
t ions.
- To reduce the risk of breathing problems,
those w ith asthma or other respiratory con­
ditions should get fresh air right away by
gett ing out of the vehicle o r opening w in­
dows or doors.
- If you are in a collision in which airbags de­
ploy, wash your hands and fa ce 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 resid ue should get into yo ur eyes,
flush them with water.

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not funct ion ing prop­
er ly cannot p rovide supplemental p rotection
in a frontal crash.
- If the airbag indicato r light
c> page 17
comes when the vehicle is be ing used, h ave
the system inspected immediate ly by yo ur
authorized Aud i dealer. It is possible that
the airbag will inflate when it is not s up­
posed to, or will not inflate when it should.
A WARNING
If the front airbag inflates, a child without a
child restraint, in a rearward-facing child safe­
ty seat or in a forward-facing child restraint
that has not been properly installed will be
ser iously injured and can be killed .
142
-Even though your vehicle is equipped with
an Advanced A irbag System, make certain
that all children, espec ia lly 12 years and
younger, always ride on the back seat prop­
erly restrained for their age and s ize.
- Always install forward or rear-facing child
safety seats on the rear seat -even with an
Advanced A irbag System.
- If you must install a rearward-facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF l ight does not
appear and s tay on, immedi ately ins tall the
rear-facing child safety seat in a re ar seat ing
position and have the a irbag system in ­
spected by your a uthorized Audi dea ler.
- A t ight tether or other s trap on a rearward­
facing chi ld restraint attached to the front
passenger seat can put too much pressure
on the weight-sensing mat in the seat and
register more weight than is actually on the
seat. The heavier weight registered can
make the system work as thoug h an adu lt
were on the seat and deploy the Advanced
Airbag when it must be suppressed causing
serious or even f atal injury to the child.
- If, in exceptional circumstances, you must
install a forward-fa cing child res traint on
the front p assenge r seat, always move the
seat into i ts rearmost posi tion in the sea t's
fore and aft ad justment range, as far away
from the ai rbag as possible . The back rest
must be adjusted to an upr ight position.
Make sure that the

position in a frontal collision so that the airbags
can provide supplemental protection.
The airbag system is not a s ubst itute for yo ur
safety belt. Rather, it is part of the overa ll occu­
pant restraint system in your vehicle. Always re­
member that the airbag system can only help to
protect you if you are wearing your safety belt
and wear ing it properly . This is why you should
always wear your safety belt, not just because
the law requires you to do soc::,
page 122, Gener ­
al information.
Remember too, airbags will deploy only once and
only in certain k inds of accidents -your safety
be lts
a re always there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have a lready dep loyed, for
examp le when yo ur vehicle str ikes or is str uck by
anothe r afte r the f irst collis ion.
This is just one of the reasons why an airbag is
not a substitute for the safety belt. The a irbag
sys tem wo rks most effec tively when used with
the safety belts. Therefore , al ways wear your
safety bel ts cor rect ly .
It is important to remember that while the sup­
p lemental knee a irbag sys tem is designed to re­
d uce the like lihood of serious injur ies, other inju­
ries, fo r example, swell ing, b ruising, and m inor
abrasions and fr iction burns can also occu r when
an airbag inflates.
The kne e airbag system basically consists of:
