110 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.
Al ways 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 wear your safe
ty belts properly¢
page 101.
A WARNING
Sitting too close to the steer ing wheel or
instrument panel will dec rease the effec
tiveness of the airbags and will increase
t he risk of personal 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 more than 10 inches
( 2 5 cm) from the steer ing whee l, investi
ga te 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 inj uries 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 104, How are safety
belts worn correctly? .
-Never let children ride unrestrained or
improperly restrained in the vehicle. Ad
just the front seats properly . If children
are not p roperly restrained, they may be
seve rely in ju red or killed when an a irbag
infla tes.
- 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 92, Proper occupant seating po
sitions.
- Always sit up right with your back against
the backres t of your seat.
- Never p lace your feet on the instrument
panel or on the seat. Always keep both
feet on the f loor in front of the sea t to
he lp preven t serio us in juries to the legs
and h ips if the airbag infla tes .
- Never re cline the front passenger 's sea t
to tra nspor t ob jec ts. Items c an al so
move into the a rea of the s ide airbag or
the front airbag during braking or in a
sudden maneuver . Objects near the air
bags can become projectiles and cause
in ju ry 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 tools and d iagnost ic equipment to properly re
p lace any airbag in your vehicle and as
sure sy stem effe ctive ness in a crash.
- Never permit salvaged or recycled air
bags to be installed in you r vehicle.

Child restraints on the front seat - some
important things to know
.. Be sure to read the important information
and heed the WARNINGS for important de
tails about chi ldren and Advanced Airbags
~ page 130.
Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
a ll chi ldren, especially those 12 years and
younger, are properly restrained for their age and s ize. The airbag on the passenger side
makes the front seat a potentially dangerous
p lace for a child to ride. The front seat is not
the safest place for a child in a forwa rd-facing
chi ld safety seat. It can be a very dangero us
p lace for an infant or a c hild in a rearward-fac
ing seat.
The Advanced Airbag System i n your veh icle
has been cert ified to comp ly with the require
men ts of United States Federa l Mo to r Veh icle
Safety Standard
208 as applicable at the time
your vehicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be t urned off ("sup
p ressed") if a chi ld up to about one year of
age restrained in one of the rear -facing or for
ward -facing infant restraints listed i n Federal
Motor Vehicle Safety Standard
208 with wh ich
the Advanced Airbag System in your vehicle
was certified has been installed o n the front
passenger seat . For a listing of the child re
straints that were used to certify compliance

- will stay on if the front passenger seat is not
occupied ,
- will stay on if there is a small child or child

page 120, Monitor
ing the Advanced Airbag System.
T he PASSENGER AIR BAG OFF light comes on
whe n the contro l unit detects a tota l weight
on the front passenger seat that req uires the
front a irbag to be turned off.
If the total weight on the front passenger
seat is more than that of a typical
1 year-o ld
c h ild but less than the weight of a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
li ght does not come on). If the PASSENG ER
AIR BAG OFF
light does not come on, the
front a irbag on t he passenger side has not
been t urned off by the elect ronic con trol unit
and can deploy if the control unit senses an
impact that meets the cond itions stored in its
memory .
For exampl e, th e airb ag may deplo y if:
- a small ch ild that is heav ie r than a typical 1
year-old ch ild is o n the front passenger seat
(regard less of whether the child is in one of
the child safety seats listed
~ page 132), or
- 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 front airbag on the passenger side may
not deploy (the PASSENGER AIR BAG OFF
light does not illum inate and stay lit) ev en if a
small ad ult o r teenager, or a passenger who is
not si tt ing uprig ht w ith their back against a
non-re clined ba ck rest w ith their feet on the

Advanced Airbag System components
The fron t passenger sea t in your vehicle h as a
lot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sensing mat, sensors, wiring, brack
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control un it when the ignit ion is on.
The control unit mon itors the Advanced Air
bag System and turns the airbag indicator
l ight on when a ma lfunction in t he system
components is detected. The func tion of the
a ir bag ind icator light is described in greater
detai l be low . Because the front passenger
seat contains important parts of the Ad
vanced A irbag System, you m ust take care to
prevent it from be ing damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air
bag System abou t the seve rity of the crash.
- An electron ic co ntrol unit, with integ rated
crash sensors for front and side impacts .

A WARNING
1
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
equipment, cellular telephones and CB
radios, etc .) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work
shop.
- Never modify the front bumper or parts
of the vehicle body .
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace
ment upholstery over the front seat
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air bag module must always be repaired
Airbag system 123
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once . After an airbag has inflated, it
must be replaced by an authori zed Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed,
it must be replaced with new replace
ment parts designed and approved espe
cially for your Audi model version . Re
placement of complete airbag systems
or airbag components must be per
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty

124 Airbag system
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-r im combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen
sion strut s, 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 example, 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 .
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec
tronic control module if the safety belt is
latched or not .
If the safety belt is being used,
the front airbag will deploy at a slightly high er rate of vehicle deceleration than if the safe
ty belt is not being used. Therefore, in a par
ticular collision, it is possible that an airbag
will not deploy at a seating position where the
safety belt is being used but will inflate at the
position where the safety belt is not being
used.
It is important that nothing interfere
with the safety belt buckles so that the sen
sors can send the correct information about
safety belt use to the electronic control unit .
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.
A WARNING
-Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con
trol module and prevent the Advanced Air
bag System from working properly.
- Always make sure that nothing can inter
fere with the safety belt buckles and that
they are not obstructed.
Knee airbags
· Description of knee airbags
The knee airbag system con provide supple
mental protection to properly restrained
front seat occupants.
Fig. 124 Drive r's airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
~ fig . 124, 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 lower
thigh areas as a supplement to the protection
by the safety belts.
If the front airbags deploy, the knee airbags
also deploy in frontal collisions when the de
ployment threshold stored in the control unit
is met
~ page 118, More important things to
know about front airbags.
In addition to their normal safety function,
safety belts help keeping the driver or front
passenger in position in a frontal collision so ..,.

126 Airbag sys te m
If the front airbags deploy, the knee airbags
a lso deploy in frontal co llisions when the de
p loyment threshold stored in the control unit
is met.
When the system dep loys fill the airbags with
a prope llant gas, and inflate between the low
er part of the instrument panel and the driver
and the lower part of the instrument panel
and the front passenger
<=> page 118, fig. 122.
Although they are not a soft pillow, they can
"cush ion" the impact and in this way they can
he lp to reduce the r isk of injury to the lower
extremities.
A ll of this takes place i n the blink of an eye, so
fast that many people don't even realize that
the airbags have deployed. The a irbags also
inflate with a great deal of force and it is im
portant for occupant safety that noth ing
should be in the ir way when they deploy.
Fu lly inflated airbags in combination with
properly worn safety belts slow down and lim
it the occupant's forward movement and help
to reduce the r isk of injury.
Important safety instructions on the
knee airbag system
Airbags are only supplemental restraints. 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 ir bags to provide supp lemental protection .
,&. WARNING
An inflating knee airbag can cause ser ious
injury. Wear ing sa fety belts inco rrectly and
improper seating positions increase the
r isk of serious personal injury and death
whenever a veh icle 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
just ing their seat positions, it is impor
tant that both the driver and the front passenge r keep their upper bodies and knees at the following m
inimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the stee ring wheel/inst ru
ment panel.
- at leas t 4 inches (10 cm) between the
knees and the lower part of the instru
ment panel.
- The risk of personal injury increases if
you lean fo rward or to the s ide, or if the
seat is improperly posi tioned and you are
not wearing yo ur safety belt. The risk in
creases even more should the a irbag de
ploy.
- Always ma ke sure that the knee airbag
can inf late without interference. Objects
between yo u and the airbag can increase
the risk of in jury in an accident by inter
fering w ith the way the a irbag deploys or
by being pushed into you as the airbag
deploys.
- Never let anybody, espec ia lly children
or anima ls in the footwe ll in front of
the passenger seat. If the a irbag de·
ploys, th is can result in serious or fatal
injur ies.
- No objects of any k ind shou ld 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 o r prevent proper deployment
of the airbag . Small objects can be
th rown thro ugh the veh icle if the air
bag deploys and injure yo u or your p as
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 child ren are incorrectly seated, their
risk of injury increases in a collision
