Important safety instructions on
monitoring the Advanced Airbag System
A WARNING t a=
An airbag system that is not functioning
properly cannot provide supplemental pro­
tection in a frontal crash .
- If the airbag indicator light¢
page 20
comes when the vehicle is be ing used,
have the system inspected immediately
by your authorized Aud i dea ler. It is pos­
sible that the a irbag will inflate when it
is not supposed to, or w ill not inflate
when it should.
A WARNING
If the front airbag inflates, a ch ild without
a child restra int, in a rearwa rd-facing child
safety seat or in a forward-facing chi ld 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 younger, a lways ride on the
back seat properly restrained for their
age and size.
- Always install forward or rea r-facing
child safety seats on the rear seat -even
with an Advanced Airbag System.
- If you must install a rearward-facing
child safety seat on the front passenger
seat because of exceptional circ umstan­
ces and the
PAS SENGER 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 yo ur au­
thori zed Aud i dea ler.
- A tight tether or other st rap on a rear­
ward-fa cing child restr aint at ta ched to
the front passenger sea t can put too
much pressure on the weight -sens ing

A irbag system 15 5
mat in the seat and reg ister 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 ser ious or
even fata l injury to the ch ild.
- If, in exceptiona l circumstances, you
must install a forward-fac ing ch ild re­
s traint o n the front passenger seat, al­
ways move the sea t into its rearmos t po­
sition in the seat's fore and aft adjust ­
ment range, as far away from the airbag
as poss ible . The backrest must be ad just­
ed to an upright pos ition. Make sure that
the
PASSENGER AIR BAG OFF light
comes on and stays on all the time when­
eve r the ignit ion is switched on.
A WARNING
- If the PASSENGER AIR BAG OFF light
does not go out when an ad ult is sitting
on t he front passenger sea t after taking
the steps described above, make su re the
ad ult is prope rly seated and restra ined at
one o f the rea r seat ing pos itions.
- Have the airbag system inspe cted by
your author ized Audi dealer befo re trans­
port ing anyone on the front passenger
seat.
(D Tips
If t h e weight-sensing mat in the front p as­
senger seat detects an empty seat, the
front airbag on the passenger side wi ll 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 o n your Aud i. Insta lling,
removi ng, servicing or repa iring a par t in an
ar ea of the veh icle can damage a part of an
a irbag system and p reven t that system from
wor kin g p ro perly in a coll is io n. .,,.

dealer is familiar with these requirements
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-r im 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 .
The sensors in the safety belt buckle for the
d river 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 suspension components
that do not have the same performance
Airbag system 157
characteristics as the components origi­
nally installed on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
.&_ 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
Applies to vehicles: wit h knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
Fig. 144 Driver 's knee airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
Q fig . 144, 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 deploy in frontal collisions when the de­ ployment threshold stored in the control unit
I),-

is met c'> page 151, More important things to
know about front airbags.
I n addition to their normal safety function,
safety bel ts he lp keep t he d river or front pas­
senger in position in a frontal coll is ion so that
the airbags can provide supplemental protec­
tion.
The airbag system is not a s ubst itute for yo ur
safety be lt . Rathe r, it is part of the overall oc ­
cupant restraint system in you r vehicle. Al­
ways remember that the airbag system can
only help to protect you if you are wearing
you r safety belt and wear ing it properly . This
is why you shou ld always wear your safety
belt, not just because the law requires you to
do so
c:'> page 134, General notes .
The safety belt buck le for the driver and front
seat passenge r have switches that tell the a ir ­
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 sligh tly higher
rate of decelera tion than if the belt is not be­
ing used . Therefore, in a par tic ul ar collision, it
i s possible that an airbag will not deploy at a
seating position where the safety belt is being
used but will inflate at the pos ition where the
safety belt is not be ing used.
Remember too, airbags will deploy only once
and on ly in certain k inds of accidents -your
safety be lts are a lways there to offer protec­
tion in those accidents in which airbags are
not supposed to deploy or when they have a l­
ready deployed, fo r example whe n your veh i­
cle strikes or is struck by another after 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 works most effective ly when used with
the safety belts. Therefore, always wea r your
safe ty be lts correctly .
It is importan t to remember that while the
supplemental knee a irbag system is designed
to reduce the like lihood of serious injur ies,
o ther inj uries, fo r example , swel ling , bruising,
a nd minor abras ions and fri ct io n burns c an al ­
so occur when an airbag inflates.
The knee airbag system basically consists
of:
- The e lectronic control module
- Two inflatable ai rbags (a irbag a nd gas gen -
erator), one for the driver and one for the
front passenger
- The a irbag indicator light in the instr ument
panel
The knee airbag system will not deploy:
- when the ig nit ion is t urned off
- in frontal collisions when the deceleration
meas ured by the control unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warn-
ing/ind icato r light is on)

A WARNING
--
- Safety belts and the airbag system can
only provide protection w hen occupants
are in the proper seating position

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants .
Fig. 146 Side a irbag locat ion in the d river 's seat
The s ide airbags are located in the sides of the
front sea t backrests
~ fig. 146. They are iden­
tified by the word "AIRBAG" .
The s ide a irbag system basicall y con sists o f:
- the electronic control module and external
side impact sensors
- the two side airbags located in the sides of
the front backrests
- the airbag warning light in the instrument
cluster.
The airbag system is monitored electronically
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 driver's and front passenger's up­
per 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 value 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 ­
fine an airbag trigger 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
include, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc .
Q page 161, 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 wearing it properly . This
is anothe r reason why you should always wear
yo ur safety be lts, not j ust because the law re­
quires you to do so~
page 134, General
notes .
It is important to remembe r that w hile the
s u pplementa l side airbag system is designed
to reduce the likelihood of serious injuries,
other injuries, for example, swelling, bruising ,
and minor abrasions can 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 vehicle damage are not necessarily an indi­
cation of over-sensitive or failed airbag activa­
t ion . In some coll is ions, both front and side
airbags may inflate . Remember too, that air­
bags will deploy only once and only in ce rtain
ki nds of collisions -your safety belts a re a l­
ways there to offer protection in those acc i­
dents in which airbags are not supposed to
deploy or when they have a lready deployed.
Th e side airbag system will not deploy:
-when the ignit ion is turned off
- in side collisions when the acceleration measured by the sensor is too low
- in front -end collisions
- in rear-end collisions

- in rollovers. In some types of accidents the front airbags,
side curtain airbags and side airbags may be
trigger ed together.
& WARNING
- Safety belts and the airbag system will
only provide protection when occupants
are in the proper seating position
r:::;, page 161.
-If the airbag indicator light c:::> page 20
comes when the vehicle is being used,
have the system inspected immediately
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.
How supplemental side airbags work
-
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained .
Fig. 147 Inflated sid e airbags on left s ide of vehicle
When the system is triggered, the airbag is
f ill ed with propellant gas and breaks through
a seam in the seat surface area marked "AIR­
BAG".
It expands between the side trim panel
and the passenger . In order to help provide
this additional protection, the side airbag
must inflate within a fraction of a second at
very high speed and with great force . The sup­
plemental side airbag could injure you if your
seating position is not proper or upright or if
items are Located in the area where the sup­
plemental side airbag expand s. This applies
especially to children
c:::> page 166, Child Safe­
ty.
Supplemental side airbags inflate between
Airbag system 161
the occupant and the door panel on the side
of the vehicle th at is struck in certain side col­
li sion
c:::> fig. 147.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the upper
part of the body.
A fine dust may develop when the airbag de­ ploys . This is normal and does not mean there
is a fire in the vehicle.
Important safety instructions on the
side airbag system
Airbags are only supplemental restraints. Al­
ways properly wear safety belts and ride in a
proper seating position.
There is a lot that you and your passengers
must know and act accordingly to help the
safety belts and airbags do their job to pro­
vide supplementa l protection.
& WARNING ...
An inflating side airbag can cause serious
or fatal injury. Improperly wearing safety
belts and improper seating positions in­
crease the risk of serious personal injury
and death whenever a vehicle is being
used.
- In order to reduce the risk of injury when
the supplemental side airbag inflates:
- Always sit in an upright position and
never lean against the area where the
supplemental side airbag is located.
- Never Let a child or anyone else rest
their head against the side trim panel
in the area where the supplemental
side airbag inflates .
-Always make sure that safety belts are worn correctly,
- Do not let anyone sitting in the front
seat put their hand or any other parts
of their body out of the window .
-Always make sure that the side airbag can inflate without interference.

162 Airbag system
-Never insta ll seat covers or replace­
ment upho lstery over the front
seatbacks that have not been specifi­
cally approved by Audi.
- Never use add itional seat cushions that
cover the areas where the side airbags
deploy.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repa ired
immed iately by an authorized Audi
dealer.
- Objects between you and the airbag can
increase the risk of injury in an acc ident
by interfering with the way the airbag
unfolds or by being pushed into you as
the airbag inflates.
- Never place or attac h accessories or
other objects (such as cupholders, tele­
phone b rackets, or even large, bulky
objects) on the doors, over o r near the
a rea marked "AIRBAG" on the seat
backrests.
- Such objects and accessories can be­
come dangerous p rojectiles and cause
i n ju ry when t he supplemental s ide air­
bag deploys.
- N ever ca rry any objects or pets in the
deployment space between them and
the airbags or a llow children or other
passengers to travel in th is posit ion .
- Always use the built-in coat hooks only
for lightwe igh t clothing. Never leave any
heavy or sharp -edged objects in the
pockets that may interfere with side air­
bag dep loyment and can cause personal
injury in an accident.
- Always prevent the side a irbags from be­
ing damaged by heavy objects knocking
against or hitting the sides of the seat­
backs.
- The airbag system can only be triggered
once.
If the a irbag has been triggered,
the system m ust be replaced by an au­
thorized Aud i deale rship.
- Damage (c rac ks, deep scratches etc.) to
the original seat covers or to the seam in
the area of the side airbag module must always be repa
ired immediately by an au­
thorized Audi dealer.
- If children are seated improperly, their
risk of injury increases in the case of an
accident
c:> page 166, Child Safety.
- Never attempt to modify any compo­
nents of the airbag system in any way.
- In a side collision, side airbags will not
function properly if sensors cannot cor­
rectly measure increasing a ir pressure in­
side the doo rs whe n air escapes through
large r, unclosed openings in the door
panel.
- Never dr ive with inte rior door trim pan ­
els removed.
- Never dr ive when par ts h ave bee n re­
moved from the inside door pane l and
the ope nings they leave have not been
proper ly closed .
- Never dr ive when loudspeakers in the
doors have been removed unless the
speaker holes have been properly
closed.
- Always make certain that openings are
covered or filled if add it iona l speakers
o r other equipment is installed in the
inside door panels.
- Always have work o n the doors done by
an authorized Audi dea ler or q ualified
workshop .
Side curtain airbags
