154 Airbag sys te m
Since the cir cumstances will vary considerab ly
between one collision and anot her, it is not
possib le to def ine a range of vehicle speeds
that will cover every possible k ind and angle
of impact t hat will always trigger the airbags.
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 also not inflate in
side or rea r collisions, or in ro ll-overs .
Always rememb er: Airbags will deploy only
once, and only in certa in k inds of co llisions.
Your safety belts are always there to offer pro­
tection in those s ituations in which airbags
a re not supposed to deploy, or when they have
a lready deployed; for example, when your ve­
hicle strikes or is struck by another vehicle af­
ter the first co llision.
This is just one of the reasons why an airbag is
a supplementary restraint and is not a substi­
tute for a safety belt . The airbag system
works most effect ively when used with the
safety belts. Therefore, always properly wear
your safety belts¢
page 145.
A WARNING
Sitting too close to the steer ing wheel or
instrument panel will dec rease the effec­
t iveness of the airbags and will increase
the risk of personal injury in a collision .
- Never sit closer than 10 inches (2S cm)
to the stee ring wheel or instrument pan­
el.
- If you cannot sit more than 10 inches
( 2 5 cm) from the s teer ing whee l, investi­
gate whethe r adaptive equipmen t may
be available to help you reach the pedals
and increase your seating distance from
the steering wheel.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way, your risk of in jury is much higher.
- You will also receive serio us injuries and
cou ld even be killed if you are up against
the airbag or too close to it when it in­
flates - even with an Advanced Airbag. -
To reduce the risk of injury when an a ir­
bag inflates, always wear safety be lts
properly ¢
page 148, 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 severely injured or killed when an
airbag inflates.
- Never let children ride unrestrained or
improperly restrained in the vehicle. Ad­
just the front seats prope rly .
- Never ride with the back rest reclined.
- Always sit as far as possible from the
steer ing whee l or the instrument pane l
¢page 136.
-Always sit upright with your back against
the backrest of your 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
help prevent serio us in ju ries to the legs
and h ips if the airbag inflates.
- Never recline the front passenger 's seat
to transport objects , Items can a lso
move into the a rea of the s ide airbag or
the front a irbag du ring bra king or in a
sudden maneuve r. Objects nea r the air ­
bags can become projectiles and cause
in jur y when an airbag inflates.
A WARNING ~
Airbags that have deployed in a crash must
be replaced.
- Use on ly orig inal equipment airbags ap­
proved by Aud i and installed by a trained
technician who has the necessary too ls
and d iagnost ic equipment to properly re­
p lace any airbag in your vehicle and as­
sure system effectiveness in a crash .
- Never permit salvaged or recycled air­
bags to be installed in your vehicle.

-An improperly installed child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child -even with an Advanced Airbag
System .
- Always carefully follow the manufactur­
er's instructions provided with the child
seat or carrier .
- Never place additional items on the seat
that can increase the total weight regis­
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.
Fig. 165 Location of dr iver a irbag: i n stee ring wheel
Fig. 166 Location of front passenger's a irbag: in the in­
strument panel
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time your
vehicle was manufactured. The system senses
the position of the front seats and controls front airbag inflation with a valve, depending
Airbag system 157
on the distance between the respective seat
and the steering wheel or instrument panel.
The safety belts for the seats have "preten­
sioners" that help to take slack out of the belt
system. The pretensioners are also activated
by the electronic control 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 steering
wheel hub¢
fig. 165 and the airbag for the
front passenger is in the instrument panel ¢
fig . 166. The general location of the airbags
is marked "AIRBAG" .
There is a lot you need to know about the air­
bags in your vehicle. We urge you to read the
detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature.
Please be sure to heed the WARNINGS -they
are extremely important for your safety and
the safety of your passengers, especially in­
fants and small children.
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only supplemental protect ion .
- Airbag work most effective ly when used
with properly worn safety belts.
- Therefore, always wear your safety belts
and make sure that eve rybody in your ve ­
hicle is properly restrained .
&_ WARNING
A person on the front passenger seat, es­
pec ially infants and sma ll 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
11-

158 Airbag system
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
under the U.S . Federal Standard if a child
that is heavier 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 their own safety, all children, espe­
cially 12 years and younger, should al­
ways ride in the back properly restrained
for their age and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was manufactured .
The front Advanced Airbag System supple­ ments the safety belts to provide additional
protection for the driver's and front passeng­
er's heads and upper bodies in frontal crashes .
The airbags inflate only in frontal impacts
when the vehicle deceleration is high enough.
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts . Rather, it is part of the over­
all occupant restraint system in your vehicle .
Always remember that the airbag system can
only help to protect you , if you are sitting up­
right, wearing your safety belt and wearing it
properly. This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your vehicle has been certified to meet the "low risk" re­
quirements for 3 and 6 year-old children on
the passenger side and very small adults on
the driver side. The low risk deployment crite- ria
are intended to help reduce the risk of in­
jury through interaction with the front airbag that can occur, for example, by being too
close to the steering wheel and instrument
panel when the airbag inflates.
In addition, the system has been certified to
comply with the "suppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are restrained on the front passenger
seat in child restraints that are listed in the
Standard
¢ page 179, 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 179,
-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 ..,_

160 Airbag sys te m
- Always make su re the forward-facing
seat has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front a nd side airbag .
- Never put the forward- facing child re­
straint up aga inst or very near the instru­
ment panel.
- 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 insta lli ng
the fo rward-facing chi ld restraint. The
b ackres t must be adjusted to an upr igh t
posit ion.
- Make su re that the

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
weight-sens ing 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 unit mo nitors the Advanced Air­
bag Sys tem and turns the airbag indicator
light on when a ma lfunction in the system
components is detected . The function of the
ai rbag ind icator light is described in greater
detai l below. Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you must take care to
prevent it from be ing damaged . Damage to
the seat may prevent the Advanced A irbag for
the front passenger seat from doing its job in
a cra sh .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re ve hicle ac celera tion/de ce le ra ti on
to provide information to the Advanced Air­ bag System abo ut the severity of the crash . -
An elect ronic contro l unit, with integrated
crash sensors for front and side impacts .
The control un it "decides" whether to fi re
the front a irbags based on the informat ion
received from the crash sensors. The contro l
un it also "decides" whether the safety belt
prete nsioners shou ld be act ivated .
- An Advanced A irbag w ith gas generator and
cont ro l valve for the driver ins ide the steer ­
ing wheel hub .
- An Advanced A irbag w ith gas generator and
cont ro l valve inside the inst rument panel for
the front passenger .
- A we ight-sensing mat under the up ho lstery
padding of the front passenge r seat cushion
that measures the total weight o n the seat.
The info rma tion reg iste red is sent continu­
ously to the elec troni c control un it to regu­
la te deployment o f the front Advanced Air ­
bag on the passenger side .
- An airbag monitor ing sys tem and indicator
light in t he instr ument cluster ¢
page 164.
-A sensor in each front se at regis ters the dis ­
t ance between the respec tive seat and the
steering whee l o r instrument panel. The in­
formation registered is sent continuo usly to
the electron ic contro l unit to regulate de­
ployment of the front Adv a need A irbags .
- The
PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instr u­
ment panel ¢
page 164, fig. 168 and tells
you whe n the front Advanced Airbag on the
passe nger side has been turned off .
- A sensor below the safety be lt latch for the
front seat passe nger to measure the tension
on t he safety be lt . The tension on the safety
be lt and the weight registered by t he
weight-sens ing mat he lp the control uni t
"de cide" whe ther the front airbag fo r the
front passenge r seat should be turned off or
not ~
page 155 , Child restraints on the
front seat -some important things to
know.
- A sensor in the safety belt latch fo r th e d riv ­
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 un it .

& 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 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-sensing mat and send the
wrong information 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.
- Never use cushions, pillows, blankets or
similar items on the front passenger
seat. The additional padding will prevent
the weight-sensing mat in the seat from
accurately registering the child restraint
-
Airbag system 161
or person on the seat and prevent the
Advanced Airbag System from function­
ing properly.
- 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.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side airbags supplement the protection of­
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help reduce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the impor­
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need Airbag System
and the activation of the safety belt preten­
sioners depend on the deceleration measured by the crash sensors and registered by the
electronic control unit. The amount of infla­
tion of the front airbags can also be adapted
to the front seat position, depending on the
distance between the respective front seat
and the steering wheel or instrument panel as registered by sensors in the seats. Crash se­
verity 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, regardless of safety
belt use, the airbag will be turned off if the
weight on the passenger seat is less than the
Iii>'

electronic control unit (the PA SS ENGE R AIR
BAG OFF
light comes on and stays on).
A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the risk of injury when the air­
bags inflate, the driver and passengers
must always sit in an upright posit ion,
must not lean against or place any part
of the ir body too close to the area where
the a irbags are located .
- Occupants who are unbelted, out of posi ­
t ion or too close to the airbag can be se­
riously injured by an airbag as it unfolds
with great force in the blin k of an eye
¢page 155.
A WARNING
A child in a rearward-facing child sea t in­
stalled 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 seat
o r infant carrier with great force and w ill
smash the ch ild 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
because of exceptiona l circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rea r-facing chi ld seat in a
rear seating position and have the airbag
system inspected by your Aud i deale r.
A WARNING
Objects be tween you and the a irbag will
increase the risk of in jury in a crash by in ­
terfering with the way the air bag unfolds
or by being pushed into you as the a irbag
inflates.
-
A irbag system 163
-Never hold things in you r hands o r on
your lap when the veh icle 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
neuvers and become dangerous projec­
tiles that can cause ser ious personal in­
jury if the a irbags inf late.
- Never place or attach accesso ries o r oth ­
er objects (such as cup holders, te le­
phone b rac kets, large, heavy or bulky ob ­
jects) on the doors, ove r o r near the are a
marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those areas and yo urself. These
objects could cause in ju ry in a c rash, es­
pecially when the airbags inflate.
- Never recline the front passenger 's seat
to transport objects. Items can a lso
move into the area of the s ide a irbag or
the front a irbag during braking or in a
sudden maneuver. Objects near the air­ bags can become projectiles and cause
i nj ury, partic ula rly when the seat is re­
clined.
A WARNING
T he fine dus t create d when airbag s deploy
can cause breathing prob lems fo r people
with a history of as thma or ot her breat h­
ing cond itions.
- T o reduce the ri sk of breath ing problems,
those with asthma or other respiratory
conditions s hou ld get fresh air r ight
away by getting o ut o f the veh icle or
open ing 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 c uts or scratches .
-If the resi due should get into your eyes,
f lush them with water.

Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System: the airbag
monitoring indicator light and the
PASSEN­
GER AIR BAG OFF
light.
The Advanced Airbag System (including the
electronic control unit, sensor circuits and sys­
tem wiring) is monitored continuously to
make sure that it is functioning properly
whenever the ignition is on. Each time you
switch on the ignition, the airbag monitoring
indicator light
I (USA mode ls)/ fll (Canada
models) will come on for a few seconds (self
d iagnost ics).
The system must be inspected when the
indicator light
I (USA models)/E,I
(Canada models):
-does not come on when the ignition is
switched on,
- does not go out a few seconds after you have switched on the ignition, or
- comes on while driving.
If an airbag system malfunct ion is dete cted,
the indicator light will first start flashing to
catch the driver's attention and then stay on
continuously to serve as a constant reminder
to have the system inspected immediately.
If a malfunction occurs that turns the front
airbag on the passenger side
off, the PASSEN­
GER AIR BAG OFF
light will come on and stay
on whenever the ignition is on.
A WARNING
An airbag system that is not functioning
properly cannot provide supplemental pro­
tection in a frontal crash.
- If the airbag indicator light
c::> page 18
comes when the vehicle is be ing used,
have the system inspected immediate ly
by your authorized Audi dealer. It is pos- sible
that the airbag will inflate when it
is not supposed to, or will not inflate
when it should.

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not functioning
properly cannot provide supplemental pro­
tect ion in a frontal crash.
- If the airbag indicator light
c:> page 18
comes when the vehicle is be ing used,
have t he system inspected immediate ly
by you r authorized Aud i dea le r.
It is pos­
s ible that the a irbag will inflate when it
is not s upposed to, or w ill not inflate
w hen it sho uld.
A WARNING
If the front air bag infla tes, a c hild wi tho ut
a chil d restra int, or in a rearward-fac ing
child safety seat, or in a forward-facing
child rest raint that has not been prope rly
installed will be serious ly injured and can
be killed.
- Even though your ve hicle is equipped
with an Advanced Airbag System, make certain that all children, especially 12
years and younger, a lways ride on the
back seat properly restra ined fo r the ir
age and size .
- Always insta ll forward or rea r-facing
child seats on the rea r seat -even w ith
an Advanced Airbag System.
- If you must install a rearward-fac ing
child seat on the front passenge r seat
because of except io na l circumstances
and the
PASSENGER AIR BAG OFF ligh t
does not appe ar and stay on, imme diate- ly insta
ll the rear-facing child seat in a
rear seat ing pos ition and have the airbag
system inspected by your Audi dealer.
- A t ight tether or other strap on a rear­
ward-facing child restraint attached to
the front passenger seat can put too
much p ressu re on the weight-sensing
mat in the seat and reg iste r mor e we ight
than is actually on the seat. The heavie r
weight regis tered can make the sys tem
wo rk as though an adult we re on the seat
and deploy the Advanced Airbag when it
m ust be suppressed causing serious or
even fata l injury to t he chi ld .
- If, in exceptiona l circumstances, you
m ust install a forward-facing c hild re­
straint on the front passenger seat, al ­
ways move the seat into its rearmost po­ sition in the seat's fore and aft ad just­
ment range, as far away from the a irbag
as poss ible. The backrest mus t be ad just­
ed to an upright pos ition. Make su re that
the
PASSENGER AIR BAG OFF light
comes on and st ays o n all the time when ­
eve r the ignit ion is swit ched on .
A WARNING
- If the PASSENGER AIR BAG OFF light
does not go o ut when an a dult is sitting
on the front passenger seat after taking
the steps described above, make sure the
adu lt is properly seated and restra ined at
one of the rear seat ing pos itions.
- Have the airbag system inspected by
your Aud i dealer before transporting
a nyo ne on the front passenger seat .
(D 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 the
PASSENGER AIR BAG
OFF
light will stay on.
