140 Airbag sys tem
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 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 also not inflate in
side or rea r collisions, or in ro ll-overs .
Always remember : 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 jus t one of the reasons why an a irbag is
a supplementary restra int and is not a substi
tute fo r a safety belt . The airbag system
works most effect ively when used with the
safety belts. Therefore, always properly wear
your safety belts¢
page 130.
A WARNING
Sitting too close to the steer ing whee l 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 adap tive 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 133, 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 injured or killed when an
ai rbag 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 121.
-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 ina l 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.
142 Airbag sys te m
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instrument cluster and stays on.
I f the front passenger airbag deploys, the
F ederal Standard requires the airbag to meet
the " low risk" deployment criteria to reduce
the r isk of injury through interaction with the
a irbag. "Low risk" deployment occurs in those
crashes that take place at lower decelerations
as defined in the electronic control un it
c::> page 152, PASSENGER AIR BAG OFF light.
A lways remember, a chi ld seat or infant carri
er installed on the front seat may be struck
and knocked out of position by the rap idly in
flating passenger's a irbag in a frontal colli
sion . The airbag could greatly reduce the ef
fectiveness of the ch ild restraint and even se
rio usly inju re the child during inflat ion.
For this reason, and because the back seat is
the safest place for chi ldren - when properly
restra ined accord ing to their age and size - we
strongly recommend that children always sit in the back seat
c::> page 165, Child Safety.
_& WARNING
-
A child in a rearward -facing child seat in
stalled on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates - even with an Ad

- The inflating a irbag will hit the child seat
or 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 passenge r seat
because of exceptiona l circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi
ately install the rear-f acing chi ld seat in a

A WARNING
If, in exceptional circumstances, you must
install a forward or rearward-facing child
restraint on the front passenger's seat:
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec
tion.
- 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 .
- 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 .

protection to properly restrained front seat occupants.
Fig. 159 Locat io n of drive r airbag : in steering wheel
Fig. 160 Locat ion of fron t pa ssenger' s airbag: in the in·
st rument 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 safety belts
for the seats have "pretens ioners " that help
to take slack out of the belt system. The pre
tensioners 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. 159 and the airbag for the
front passenger is in the instrument panel
¢ fig. 160. The general location of the airbags
is marked "AIRBAG".
There is a lot you need to know about the a ir

Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
Ai rbag System in it. These parts incl ude the
capacitive passenger detect ion system, wir
i n g, brackets, and more . The control unit
monitors the system o n the front passenger
seat when the ign ition is switched on and
turns the airbag indicator light on when a
malfunct ion in the one of the system compo
nents is detected ¢ page
152 . Because the
fro nt passenger seat contains important parts
of the Advanced Airbag System, you must
t ake care to p reven t it from being damaged.
D amage to the seat may preven t the Ad
vanced A irbag 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 o f the veh icle that
measure vehicle acceleration/dece leration
to provide information to the Advanced Air
bag System about the severity of the crash .
- An electronic co ntrol unit, with integrated
crash sensors for front and side impacts .
The contro l unit "decides" whether to fire
A irbag system 147
the front a irbags based on the in format ion
received from the crash sensors. The contro l
unit also "decides" whether the safety be lt

- An Advanced Airbag with gas generator and
contro l valve for the driver ins ide the steer
ing wheel hub.
- An Advanced Airbag with gas gene rator and
cont ro l valve inside the instrument pane l for
the front passenger.
- A capacitive passenger detection system un
derneath the front passenger seat cover.
This system measures the electrical capac i
tance of the person in the seat. The informa

chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula
tions must be observed. Your authorized
Audi dealer is familiar with these require
ments and we recommend that you have
your dealer perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag sensors and sent to the electronic control
unit. Some suspension changes can, for exam
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made . Other kinds of
changes may reduce the force levels meas ured by the sensors and prevent the airbag
from deploying when it should.
A WARNING
Changing the vehicle's suspension includ
ing use of unapproved tire-rim combina
tions can change Advanced Airbag per
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance characteristics as the components origi
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
Knee airbags
Description of knee airbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supple
mental protection to properly restrained
front seat occupants .
Fig. 163 Driver 's knee airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
¢ fig. 163, the airbag for the passenger is at
about the same height in the instrument pan
el underneath the glove compartment.
The knee airbag offers additional protection
to the driver 's and passenger's knees and up
per and lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags
also dep loy in frontal collisions when the de
ployment threshold stored in the control unit
is met
<=> page 149, More important things to
know about front airbags .
In addition to their normal safety function,
safety belts help keep the driver or front pas
senger in position in a frontal collision so that
the airbags can provide supplemental protec
tion.
The airbag system is not a substitute for your
safety belt . Rather, it is part of the overall oc
cupant restraint system in your vehicle. Al
ways remember that the airbag system can
only help to protect you if you are wearing
your safety belt and wearing it properly. This
is why you should always wear your safety
belt, not just because the law requires you to
do so

Remember too, airbags will deploy only once
and only in certain kinds of accidents -your
safety belts are a lways there to offer protec
tion in those acc idents in which airbags are
not supposed to deploy or when they have al
ready deployed, for example when your vehi
cle str ikes or is struck by another afte r the
fi rst coll is ion.
This is just one of the reasons why an a irbag is
not a substitute for the safety belt . The airbag
system wo rks most effectively when used with
the safety belts . Therefore, always wear your
safety bel ts correctly .
It is important to remember that while the
supplemental knee a irbag system is des igned
to reduce the like lihood of serious injur ies,
o ther in juries, fo r example, swel ling , bruising
and minor abras io ns and frict ion bu rns ca n al

The knee airbag system basically consists
of :
-The elec tronic control mod ule
- T wo inf latab le airbags (airbag and gas gen-
erato r), one for the driver and one for the
front passenger
- T he airbag ind icator light in the instrument
pane l
The knee airbag system will not deploy:
-when the ign ition is switc hed off
- in frontal collisions w hen the decelerat ion
measured by the control unit is too low
- in s ide collisions
- in rear-end collisions
- in ro llovers
- in the event of a system malfunct io n (wa rn -

If the front airbags dep loy, the knee airbags
also dep loy in fronta l collisions when the de

Important safety instructions on the
knee airbag system
Applies to vehicles: with knee airbags
Airbags are only supplemen tal res traints. Al
ways wear safety belts correctly and ride in a
proper seating position .
There is a lot that you and your passengers
must know and do to help the safety belts and
a irbags to provide supplemental protection .
A WARNING
An inflating knee airbag can cause serious
injury. Wearing safety belts incorrectly and
improper seating positions increase the
r isk of serious personal injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you are seated too close
to any of the airbag locations. When ad
justing their seat positions, it is impor tant that both the driver and the front
passenger keep their upper bodies and
knees at the following minimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru
ment panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru
ment panel.
- T he 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 you and the airbag can increase
the risk of injury in an accident by inter
fering with the way the airbag deploys or by being pushed
into you as the airbag
deploys .
- Never let anybody, especially children
o r anima ls ride in the footwell in front
of the passenger seat. If the airbag de
ploys, this can result in serious or fatal
injuries.
- Never carry objects of any kind in the
footwell area in front of the dr iver's or
passenger's seat. Bulky objects (shop
ping bags, for example) can interfere
with 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 ch ildren are incorrectly seated, their
risk of injury increases in a collision
