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 safety belts
for the front seats have "pretensioners" that
help to take slack out of the belt system. The
pretensioners are also activated by the elec­
tronic control unit 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 steer ing
wheel hub¢
fig. 119 and the airbag for the
front passenger is in the instrument panel
¢
fig. 120. 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
Airbag system 119
detailed information about airbags, safety
b elts 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 supplementa l protect ion.
- 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.
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 .
- Altho ugh the Advanced Airbag System in
your veh icle 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 imposs ible 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
under the U .S. Federal Standard if a child
that is heavie r than the typical one-year
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 its own safety, a child should always
ride properly restrained for its age and
size.

120 Airbag sys te m
Advanced front airbag system
Yo ur veh icle is equippe d with a fro nt Advanced
A ir b ag System in com pliance with Un ited
States Federal Motor Vehicle Safety Standard 208 as applicab le at the time your vehicle was
manufactured.
The front Advanced Airbag Sys tem supp le­
ments the safety belts to provide addit ional
protection for the driver's and front passeng­
er's heads and upper bodies in frontal crashes.
The airbags inflate only in fronta l impacts
when the vehicle dece lerat ion is high enough.
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety be lts. Rather, it is part of the over ­
all occupant restraint system in your veh icle.
Always remember that the airbag system can
only help to protect you, if you are s itting up­
right, wear ing you r safety belt and wearing it
properly. This is why you and your passenge rs
must always be properly restra ined, not just
beca use the law requires you to be.
The Advanced Airbag System in your veh icle
has been cert ified to meet the "low risk" re­
qu irements for
3 and 6 year-o ld childre n on
the passenger side and very small adu lts on
the dr iver side. The low risk deployment cri te ­
ria are intended to he lp red uce the risk of in ­
jury through interaction with the front airbag
that can occ ur, for example, by be ing too
close to the steer ing wheel and instrument
panel when the airbag i nflates.
I n addition, the system has been certif ied to
comp ly with the "suppression" requirements
of the Safety Standard, to turn off the front
a irbag for infants
12 months old and younger
who are restra ined on the front passenger
seat in ch ild restra ints that are listed in the
Standard
~ page 138, Child restraints and
Advan ced Airbags.
"Suppression" requires the front airbag on the
passenger side to be tur ned off if:
- a ch ild up to about one year of age is re­
stra ined on the front passenger seat in one
of the rear -facing or forwa rd -facing infant restraints listed in Federal
Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your veh icle was
cert ified. For a listing of the child restraints
that were used to certify your vehicle's com­
pliance w ith the US Safety Standard
~page 138,
-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
we ight of a chi ld that is about
1 year old re ­
stra ined in one of the rear-facing o r forward­
facing infa nt restraints ( listed in Fede ral Mo­
tor Vehicle Safety Standa rd 208 w it h which
t h e Advan ced Airbag Sys tem in yo ur vehicle
was certif ied), the front air bag on the passen­
ger side may or may not deploy .
T he
PASSENGER AIR BAG OFF light comes on
whe n the elec tro nic con tro l unit detects a to­
ta l we ight on the fron t passenger seat that re ­
quires the front airbag to be t urned off . If the
PASSENGER AIR BAG OFF light does not
come on, the front a irbag on the passenger
s ide has not been t urned off by the contro l
unit and ca n dep loy if the control u nit senses
an impact that meets the cond itions 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 we ight of a small adult, the
front a irbag on the passenger side may dep loy
(the
PASSENG ER AIR BAG OFF light does not
come on).
For example, the airbag may deploy if:
- a small ch ild that is heav ier than a typical 1
year-old ch ild is on the front passenger seat
(regard less of whether the child is i n one of
the child safe ty seats listed
~ page 138),
-a child who has outgrown child restraints is
on the front passenger seat .
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light in the center
of the instrument panel will come on and stay o n . ..,.

-The inflating airbag will hit the child
safety seat or infant carrier with great
force and w ill smash the ch ild safety seat
and child against the backrest, center
arm rest, door or roof.
- 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 no t come on and stay on, im­
med iately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
Audi dealer .
&_ WARNING
Objects between you and the airbag will
increase the risk of in jury in a crash by in­
terfering with the way the airbag unfolds or by being pushed into you as the a irbag
inflates.
- Never hold th ings 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 dur ing braking or other sudden ma­
neuver and become dange rous projec­
t il es that can cause serious personal in­
jury if the airbags inflate.
- Never place o r attach accessories or oth­
er objects (such as cup ho lders, tele­
phone brackets, large, heavy or b ulky 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 dur ing braking or in a
sudden maneuver. Objects near the air­
bags can be come project iles and cause
injury, part icularly when the seat is re­
cl ined.

&_ WARNING
The fine dust created when airbags deploy
can cause breathing prob lems fo r people
with a history of as thma or other breath­
ing cond itions.
- To reduce the risk of breath ing problems,
those with asthma o r other respiratory
conditions s hou ld get fresh air r ight
away by getting o ut of the veh icle or
open ing windows or doors.
- If you are in a collision in which airbags
deploy, wash your hands and fa ce with
mild soap and wate r before eating.
- Be ca reful not to get the dust in to your
eyes, o r into any c uts or sc ratches.
- If the residue should get into your eyes,
f lush them w ith wate r.
Monitoring the
Advanced Airbag System
fl~ Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System: the airbag
monitoring indicator light and the
PASSEN­

light.
T he Advanced A irbag System (includ ing the
electron ic co ntro l unit, sensor circu its and sys­
tem wiring) is monitored continuously to
make sure that it is function ing properly
whenever the ignition is on. Each time you
turn on the ignition, the airbag mon itoring in­
dicator light

bed in the chi ld restraint manufacturer's
instruct ions;
- make sure that the convertible locking fea­
ture on the safety belt for the front passen­ ger seat has been activated and that the
safety belt has been pulled tight. The belt must not be loose or have loops of slack so
that the sensor below the safety belt latch
on the seat can do its job
~ page 144 .
-make sure that th ings that may increase the
weight of the ch ild and child safety seat are
not being transpo rted on the front passen­
ger seat;
- make sure that the safety belt tension sen­
sor is not b locked. Shake the safety belt
latch on the front passenge r sea t back and
forth;
- If a st rap or tether is being used to tie the
child safety seat to the front passenger
seat, ma ke s ure that i t is not so tight tha t it
ca uses the weight -sensing mat to meas ure
more weight than is actually on the seat .
If the PASSENGER AIR BAG OFF light still
d oes not come o n
and does not stay on con­
tinuously (when the ignition is switched on),
- ta ke the ch ild restraint off the front passen-
ger seat and insta ll it p roperly at one of the

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An ai rbag system that is not functioning
p roperly cannot provide supplemental pro­
tection in a frontal crash.
- If the airbag ind icator light comes on, it
means that there may be something
wrong wi th the Advanced Airbag Sys tem.
It is poss ible that the ai rbag w ill inflate
when it is not supposed to, or will not in ­
f late when it sho uld .
- Have the airbag system inspected imme­
diate ly by yo ur Audi dealer.
A WARNING
If the front airbag inflates, a child without
a child restraint, in a rearward -facing child
safety seat or in a forward-facing child re­
straint that has not been proper ly installed
-
will be ser ious ly injured and can be killed. ~

128 Airbag system
-Even though your vehicle is equipped
with an Advanced Airbag System, make
certain that all children, especially 12
years and younger, always ride on the
back seat properly restrained for their
age and size.
- 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 appear and stay on, imme­
diately install the rear-facing child safety
seat in a rear seating position and have the airbag system inspected by your Audi
dealer.
- A tight tether or other strap on a rear­
ward-facing child 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 though an adult were on the seat
and deploy the Advanced Airbag when it
must be suppressed causing serious or
even fatal injury to the child.
- If, in exceptional circumstances, you
must install a forward-facing child re­
straint on the front passenger seat, al­
ways move the seat into its rearmost po­
sition in the seat's fore and aft adjust­
ment range, as far away from the airbag
as possible. The backrest must be adjust­
ed to an upright position . Make sure that
the
PASSENGER AIR BAG OFF light
comes on and stays on all the time when­
ever the ignition is switched on.
A WARNING
- If the PASSENGER AIR BAG OFF light
does not go out when an adult is sitting
on the front passenger seat after taking
the steps described above, have the air­
bag system inspected by your Audi deal­
er before transporting anyone on the
front passenger seat.
-
(!) Tips
If the weight-sensing mat in the front pas­
senger seat detects an empty seat, the
front airbag on the passenger side will be
turned
off, and PASSENGER AIR BAG OFF
will stay on.
Repair , care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision.
There are some important things you have to
know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment.
A WARNING
-Improper care, servicing and repair proce-
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys-
tem (including the installation of audio
II),

The safety belt buckle for the driver and front
seat passenger have switches that tell the air­
bag control mod ule if the safety belt is being
used or not. If the safety belt is being used,
the knee airbag will deploy at a slightly higher
rate of deceleration than if the belt is not be­
i ng used. Therefo re, i n a pa rtic ular collision, it
is poss ible that an airbag will not deploy at a
seating position whe re the safety belt is being
used but will inflate at the position whe re the
safety be lt is not being used .
R emembe r too, airbags will deploy only once
and on ly in ce rtain kinds of accidents -your
safety be lts are a lways there to offer pro te c­
t ion in those acc idents in which airbags are
not supposed to deploy or when they have a l­
ready deployed, fo r example when your vehi­
cle strikes or is struck by another after the
f irst coll is ion.
This is just one o f th e reasons why an ai rbag is
not a substitute for the safety belt . The airbag
system works most effective ly when used with
the safety belts. Therefore, always wear your
safety belts correctly .
It is important to remember that while the
supp lemental airbag system is designed to re­
duce the likelihood of serio us inj uries, other
in juries, for example, swel ling, bruising, and
minor abrasions can also be associated with
a ir bags .
The knee airbag sy stem ba sically consist s
of:
- The electronic control modu le
- Two inflatable airbags (airbag and gas gen-
erator), one for the driver and one for the
front passenger
- The airbag indicator light in the instrument
panel
The knee airbag sy stem will not deploy :
-when the ignition is turned off
- in fron t-end col lisions w hen the dece lerat ion
measured by the control unit is too low
- in s ide collisions
- i n rear-end colli sions
- in ro llovers

A WARNING
-Safety belts and the airbag system can
only provide pr otection w hen occupants
are in the proper seating position
r=>poge 124.
-If the ai rbag ind icator light comes when
the vehicle is be ing used, have the sys­
tem inspected immediate ly by yo ur au­
thori zed A udi deal er. The airbag may not
wo rk p roperly when the vehicle a ccele ra­
tion in a side col lision i s high enough to
dep loy the airbag. See also

How knee airbags work
The risk of injury to the leg area is reduced by
fully deployed knee airbags.
Fig. 1 24 In flated a irbags protec ting in a fronta l coll i­
sio n
The knee airbag system has been designed so
that the a irbags for the driver and front pas­
senger are dep loyed in certa in but not a ll
fron tal coll is io ns.
If the front a irbags dep loy, the knee a irbags
also dep loy in fronta l co llisions above ace r­
ta in seve rity .
When the system is dep loyed, the a irbags
start to fill w ith a propellant gas, and inflate
betwee n the lower pa rt of the instrument
panel and the driver and the lowe r part of the
in strume nt pa nel and the fron t passenger
r=> page 124 , fig . 12 1.
Although they are not a soft p illow , they can
"c ushion" the impact and in th is way they can

help to reduce the risk of injury to the lower
extremit ies.
All this takes place instantaneously, so fast
that many people don 't even realize that the
airbags have deployed. The airbags also in­
flate with a great deal of force and it is impor­
tant 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.
Important safety instructions on the
knee airbag system
Airbags are only supplemen tal res traints. Al­
ways wear safety belts correctly and ride in a
proper seating position.
The re is a lot tha t you and your passengers
must know and do to help the safety belts and
airbags to provide supplemental protection .
A WARNING
An inflating knee airbag can cause serious
injury. Wearing safety belts incorrectly and
improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used .
- The airbag system cannot protect you
properly if you are seated too close to
any of the airbag locations. When adjust­
ing their seat positions, it is important
that both the driver and the front pas­
senger keep their upper bodies and
knees at the following minimum safe
distances:
- 10 inches (25 cm) between the chest
and the steering wheel/instrument
panel.
- 4 inches (10 cm) between the knees
and the lower part of the instrument
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 yourself and the airbag can in­
crease the risk of injury in an accident by
interfering with the way the airbag de­
ploys or by being pushed into you as the
airbag deploys.
- No persons (children) or animals
should ride in the footwell in front of
the passenger seat.
If the airbag de­
ploys, this can result in serious or fatal
injuries.
- No objects of any kind should be car­
ried in the footwell area in front of the
driver 's or passenger's seat . Bulky ob ­
jects (shopping bags, for example) can
hamper or prevent proper deployment
of the airbag . Small objects can be
thrown through the vehicle if the air­
bag deploys and injure you or your pas­
sengers.
- Make sure there are no cracks, deep
scratches or other damage in the area of
the instrument panel where the knee air­
bags are located.
- If children are incorrectly seated, their
risk of injury increases in the case of an
accident

A WARNING ,~
If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
-Always follow the manufacturer's in­
structions provided with the child safety
seat or carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the child restraint. The backrest must be
adjusted to an upright position.
- Always make sure that the
PASSENGER
AIR BAG OFF light comes on and stays
on all the time whenever the ignition is
switched on.
Advanced front airbag system and children
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 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 small adults on the
driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the 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 "sup­
pression" requirements of the Safety Stand­
ard, to turn
off the front airbag for infants up
to 12 months who are restrained on the front
passenger seat in child restraints that are list­
ed in the Standard.
Child Safety 137
Even though your vehicle is equipped with an
Advanced Airbag system, a child should al­
ways ride in theseat properly restrained for its
age and si ze . 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 safety seat . It can be a very dangerous
place for an infant or a larger child in a rear­
ward-facing seat.
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in your vehicle detects the presence of an infant or child in a
child restraint on the front passenger seat us­
ing the weight -sensing mat in the seat cush­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight -sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger
seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the
seat. The weight of a child restraint and its
"footprint" vary for different kinds of child re­
straints and for the different models of the
same kind of child restraint offered by child
restraint manufacturers .
The weight ranges for the individual types,
makes and models of child restraints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in­
fants and typical 1 year-old child have been
stored in the control unit of the Advanced Air­
bag System. When a child restraint is being
used on the front passenger seat with a typi­
cal 1 year-old child, the Advanced Airbag Sys­
tem compares the weight measured by the
weight sensing mat with the information stor­
ed in the electronic control unit.
The electronic control unit also registers the
tension on the front passenger safety belt. ..,. •
