A WARNING
To reduce the risk of injury when an airbag
inflates, always wear safety belts properly.
- If you are unrest raine d, lean ing forward,
sitting sideways or out of position in a ny
way, your risk of injury is much higher.
- You w ill also receive serious injuries and
could even be killed if you are up against
the a irbag or too close to it when it in­
flates - even with an Advanced Airbag
~page 140.
More important things to know about
front airbags
Fig. 152 Inf lated front a irbags
Safety belts are impo rtant to help keep front
seat occupants in the p roper seated pos ition
so that airbags can unfo ld properly and pro­
v ide supp lemental protection in a fronta l col­
lision.
The front a irbags are designed to provide ad­
d itiona l protection for the chest and face of
the dr iver and the front seat passenge r when:
- safety belts are worn prope rly,
- the seats have been posit ioned so that the
occupant is properly seated as far as possi­
ble from the a irbag,
- and the head restraints have been properly adjusted .
Because airbags i nflate in the blink of an eye
with great force, things you have on your lap
or have placed on the seat could become dan ­
ge ro us projectiles, and be pushed into you if
the airbag inflates.
When an a irbag deploys, fine dust is released.
This is normal and is not caused by a fire in
A irba g sy stem 149
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 remembe r that wh ile the
supplementa l airbag system is designed to re­
duce the like lihood of serious injuries, other
injur ies, for example swelling, br uis ing and
minor abrasions, can also happen when air­
bags inflate. Airbags do not protect the arms
or the lower parts of the body . Front a irbags
o nly supplement the three point safe ty belts
in some fronta l co llisions in which the vehicle
decelera tion is h igh enough to deploy the air­
bags.
Front airbags will not deploy :
- if the ignition is sw itched off when a crash
occu rs,
- in side co llisions,
- in rear-end collisions,
- in rollovers,
-when the crash deceleration measured by the airbag system is less than the minimum
threshold needed for airbag dep loyment as
reg istered by the electronic contro l unit .
The front pa ssenger ai rbag will also not
deploy:
- when the front passenger seat is not occu ­
pied,
- when the weight on the front passenger
seat as sensed by the Advanced Airbag Sys­
tem ind icates that the front airbag on the
passe nger side has to be turned off by the
electronic control unit (the
PASSENGER AIR
BA G OFF
light comes on and stays o n).
A WARNING
-Sitting in the wrong pos ition can in crease
the r is k of se rious inj ury i n crashes.
- To reduce the risk of injury when the air­
bags inflate, the drive r and passenge rs
m ust always s it in an upr igh t position,
m ust not lean against or pla ce any part
of their body too close to the area whe re
the airbags a re located. .,.

~pag e 141 .
A WARNING
-
A child in a rearward -faci ng child safety
s e at insta lled on the front passenger seat
w ill be seriously injured and can be k illed if
the front a irbag inflates -even with an Ad ­
vanced Airbag System.
- T he inflating a irbag will hit the child
safety seat or infant carrier with g reat
force and wi ll smash the chi ld safety seat
and child against the backrest , center
armrest, door or roof .
- Always install rear -facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circ umstan­
ces and the
PAS SENG ER AIR BAG OFF
light does not come on and stay on, im ·
med iately install the rear-facing child
safety seat in a rear seating position and
have the a irbag system inspected by you r
authori zed Audi dealer .
A WARNING
Objects between you and the a irbag will
increase the risk of inj ury in a crash by in­
terfering wi th the way the airbag unfolds
or by being pushed into yo u as the a irbag
inflates.
- Never hold th ings in your hands or on
yo ur lap when the vehicle is in use.
- Never transport items on or in the area
of the front passenge r seat . Objects
cou ld move into the area of the front air­
bags during braking or other s udden ma­
neuver and become dangerous projec­
t iles that can cause serious personal in­
jury if the airbags inflate .
- Never place or attach accessories or oth­
er objects (such as cupholders, te le­
phone brackets, la rge, heavy or b ulky ob -
-
jects) on the doors, over or near the area
marked "AIRBAG" on the steer ing whee l,
instr ument panel, seat backrests or be­
tween those areas and yourself . These
objects could cause in jury in a crash, es­
pecia lly 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 airbag or
the front a irbag du ring bra kin g or in a
sudden maneuver. Objects nea r the air­
bags can become projec tiles and cause
inj ury, partic ularly when the seat is re­
clined .
A WARNING ~
The fine dust created when airbags deploy
can cause breathing prob lems for people
with a history of asthma or other breath­ i ng cond itions .
- To reduce the risk of breath ing problems,
those with asthma or other respiratory conditions shou ld get fresh air right
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 face with
mild soap and wate r before eating.
- Be ca reful not to get the dust into your
eyes, o r into any c uts or sc ratches .
- If the res id ue should get into your eyes ,
f lush them w ith wate r.

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An a irbag system that is not functioning
properly cannot provide supplemental pro­
tection in a frontal c rash.
- If the airbag ind icator light
¢ page 20
comes when the veh icle is being used,
have the system inspected immediately
by your authorized Audi dealer .
It is
-

possible that the airbag will inflate when
it is not supposed to, or will not inflate
when it should.
A WARNING
If the front airbag inflates, a ch ild without
a c hild restra int, in a rearward-facing c hild
safety seat or i n a forward-facing child re­
st raint that has not been properly insta lled
w ill be seriously injured and can be k illed.
- Even though your veh icle is equipped
with an Advanced Airbag System, make certain that a ll children, especially 12
years and younge r, a lways ride on the
back seat properly restrained fo r their
age and size.
- Always instal l forw ard or rea r-facing
child safety seats on the rear seat -even
with an Advanced Airbag System.
- If you mus t install a rearward -facing
child safety seat on the front passenger
seat because of exceptional circ umstan­
ces and the
PASSENGER AIR BAG OFF
light does not appear and stay on, imme ­
diately install the rear-fac ing ch ild safety
seat in a rear seating position and have
the a irbag system inspected by you r au­
tho riz ed Aud i dea le r.
- A tight tether or other strap on a rear­
wa rd-fac ing child restra int attached to
the fro nt passenger sea t can put too
much pressure on the weight-sens ing
mat in the seat and register mo re weight
than is ac tually on the seat. The heavier
weight registe red can make the system
wor k as though an adu lt were on the seat
and dep loy the Advanced Airbag when it
must be suppressed caus ing serious or
even fatal injury to the child .
- If, in exceptional circumstances, you
must install a forward-facing child re­
st rain t on the front passenger seat, a l­
ways move the seat into its rearmost po­
sit ion in the seat's fo re and aft adjust­
ment r ange, as far away from the airb ag
as possib le. The backrest m ust be adjus t­
ed to an upr ight position. Make sure that
A irbag system 153
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 tak ing
the steps described above, make su re the
adu lt is prope rly seated and restra ined at
one o f the rea r seat ing pos itions.
- Have the airbag system inspected by
your author ized Audi dealer befo re trans­
port ing anyone on the front pas senger
seat.
@ Tips
If t he weig ht-sensing mat in the front pas­
senger seat detects an empty sea t, the
front airbag on the p assenger 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 p laces on your Aud i. Insta lling,
removing, servicing or repa iring a part in an
area of the vehicle can damage a part of an
a irbag system and p revent that system from
working p rope rly in a coll is ion.
There are some important t hings you have to
k n ow to make sure that the effectiveness of
t h e system w ill not be impaired and that d is­
ca rded components do not cause injury o r pol­
l ute the environment.
A WARNING
Im proper care, serv icing a nd rep air proce­
d ur es can increase the risk of personal in ­
ju ry and death by preventing an a irbag
from deploying when needed or deploying
an a irbag unexpectedly:
- Never cover, obst ruct, or change the
steer ing whee l horn pad or airbag cover
or the instrument panel or mod ify them
in any way. •
•

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
measured by the sensors and prevent the air ­
bag 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 .
& 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 suspens ion 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 1= -
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.
Airbag system 155
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. 154 Driver 's knee airbag
The dr iver knee airbag is in the instrument
panel underneath the steering wheel
¢ fig. 154, the knee airbag for the passenger
is at about the same height in the instrument
panel 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 impor tant things to
know abou t 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 pro tec­
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 be lt and wearing it properly. This
is why you should always wear your safety
belt, not just because the law requires you to
do so
¢ page 132, General notes. ..,_

156 Airbag system
The sa fety belt buck le for the driver and front
seat passenger have switches that te ll the ai r­
bag control module 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. The refore, in a pa rticu la r collision, it
is possible that an airbag will not deploy at a
seating position where the safety belt is being used but will infla te at the position where the
safety bel t is not be ing used.
Remember too, airbags will deploy only once
and on ly in ce rtai n kinds of accidents -your
safety bel ts are always there to offer pro tec­
tion in those acc idents in which airbags a re
not supposed to deploy or when they have a l­
ready deployed, for example when your vehi­
cle strikes or is struck by another after the
f irst coll is ion.
This is just one of the reasons why an ai rbag is
n ot 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 whi le the
supp lemental knee a irbag system is designed
to reduce the likelihood of serious injur ies,
other injuries, for example, swell ing, bruising,
a nd minor abras ions and frict ion burns can al­
so occur when an a irbag inflates .
The knee airb ag sy stem basically con sists
of:
- The electronic control module
- Two inflatable airbags (airbag and gas gen-
erator), o ne 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 frontal collis ions when the dece lerat ion
measured by the contro l unit is too low
- in s ide collisions
- in rear-end collisions
- in ro llovers -
in the event of a system malfunction (warn ­
ing/indicator light is on)

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants .
Fig. 156 Side a irbag locat io n in the dr iver 's seat
The s ide airbags are located in the sides of the
front sea t bac krests
~ fig. 156. They are iden­
tified by the word "AIRBAG" .
The sid e airbag system basicall y consis ts of :
-the electronic control module and external
side impact sensors
- the two side airbags located in the sides of
t h e front backrests
- the a irbag warn ing light in the instrument
cluster.
The airbag system is monitored electronica lly
to make certain that it is functioning properly at all times. Each time you turn on the igni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics) .
The s ide airbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the drive r's and front passenger's up­
pe r torso on the side of the vehicle that is
struck in a side col lision . The airbag deploys
on ly in side impacts and on ly when the veh icle
acceleration registered by the control unit is h igh eno ugh . If this rate is below the refer­
ence va lue programmed into the control un it,
the side airbags will not be triggered, even
though the car may be badly damaged as a re­ sult of the collision. It is not possible to de ­
f ine an a irbag tr igger ing range that will
cover
every
possible angle of impact, since the cir­
cumstances w ill
vary considerably between one collision and another.
Important factors
incl ude, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc .
Q page 159, Important
safety instructions on the side airbag system .
Aside from their normal safety function, safe­
ty belts work to help keep the driver or front
passenger in position in the event of a side
collision so that the side airbags can provide
protection .
The airbag system is
not a substitute for your
safety belt. Rather, it is part of the overa ll oc­
cupant restraint system in your vehicle. Al­
ways remember that the side airbag system
can only help to protect you if you are wea ring
your safety belt and wea ring it p roperly . This
is anothe r reason why you should always wear
yo ur safe ty be lts, no t ju st because the law re­
quires yo u to do so~
page 132, General
notes .
It is impo rtant to remembe r th at w hile the
s u pplementa l side airbag system is designed
to reduce the likelihood of ser ious inju ries,
othe r injuries, for example, swelling, br uising,
and minor abrasions ca n also be associated
with deployed side airbags. Remember too,
s ide airbags will deploy only once and only in
certain kinds of accidents -your safety belts
are always there to offer protection .
Vehicle damage, repair costs or
even the lack
of ve hicle damage are not necessarily an ind i­
cation of over-sensitive or failed airbag activa­
t io n. In some coll is ions, both front and side
airbags may inflate . Remembe r too, t hat air­
bags will deploy only once and on ly in ce rtain
ki nds of col lisions -yo ur safety belts a re a l­
ways there to offer pro tection in those acc i­
den ts in which airbags are not supposed to
deploy or when they have a lready deployed.
The side airbag system will not deploy:
- when t he ignit ion is tu rned off
- in side co llisions when the acceleration
measured by the sensor is too low
- in front -end collisions
- in rear-end collisions
