system from working properly.
- Never place seat covers or rep lacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats .
- Seat covers can prevent the Advanced Air­
bag System from recognizing child re­
straints or occupants on the front passenger
seat and prevent the side a irbag in the seat
backrest from deploying properly.
- Never use cush ions, pillows, blankets or
similar items on the front passenger seat.
The add it ional padding will prevent the
weight-sens ing mat in the seat from acc u­
rately reg istering the ch ild restraint or per­
son on the seat and prevent the Advanced
Airbag System from funct ioning properly.
- If you must use a child rest raint on the front
passenge r seat and the child restraint man­
ufacturer 's instructions require the use of a
towel, foam cushion or something else to properly position the ch ild restraint, make
certain that the
PA SSENGER AIR BAG OFF
light comes on and stays on whenever the
child restraint is installed on the front pas­
senger seat.
- If the
PASSEN GER AIR B AG OFF light does
not come on and stay on, immed iately in­
stall child restraint in a rear seating position and have the airbag system inspected by
yo ur autho rized Aud i deale r.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
airbags supplement the protection offered by the
front three-po int safety belts with pretensioners
and load limiters and the adjustable head re­
stra ints to help reduce the r isk of injury in a wide
range of accident and crash situations. Be sure to read the important informa tion about safety and
heed the WARN INGS in t his chapter.
Deployment of the Advanced Airbag System and
the act ivat ion of the safety belt pretensioners de­
pend on the deceleration measu red by the crash
sensors and regis tered by the electronic control
unit. Crash severity depends on speed and decel-
156 eration as well as the mass and stiffness of the
vehicle or object involved in the crash
.
On the passenger side, regard less of safety be lt
u se, the airbag will be turned off if the weight on
the passenger seat is less than the amount pro­
grammed in the electronic control unit . The front
airbag on the passenger side will also be turned
off if one of the child safety seats that has been certified under Federal Motor Vehicle Safety
Standard 208 has been recogn ized on the seat .

A WARNING
To reduce the ris k of injury when an airbag in ­
f lates, always wea r safety belts properly.
- If you are un restrained, leaning forward, sit ­
ting sideways or out of position i n any way,
your risk of injury is much higher.
- You will a lso receive serious injuries and
could even be killed if you are up against the
airbag or too close to it when it inflates -
even with an Advanced Airbag

Airbag syste m
-Never h old things i n your hands or on your
lap whe n the vehicle 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 airbags dur­
ing brak ing or other sudden maneuver and
become dangerous projectiles that can
ca use serious personal injury if the a irbags
inflate.
- Never place or attach accessor ies or other
objects (such as cupholders, telephone
brackets, large, heavy o r bulky objects) on
the doors, over or nea r the area marked
"AIRBAG" on the steering wheel, instru­
ment pane l, seat backrests or between
those areas and yourself. These objects could cause injury in a c rash, especially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objects. Items can also move into
the area of the side airbag or the front a ir­
bag dur ing braking or in a sudden maneu­
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined.
A WARNING
The fine dust created when airbags deploy can
cause breathing p roblems for people w ith a
his to ry of asthma or o ther b reathing condi­
tions .
- T o reduce the risk of brea thing problems,
those w ith asthma or o ther respiratory con­
ditions should get fresh air right away by
getting out of the vehicle or o pening win­
dows or doors.
- If you are in a collision in which airbags de ­
ploy, wash your hands and face with mild
soap and water before eat ing.
- Be careful not to get the dust into your eyes,
or into any cuts or scratches.
- If the resid ue should get into your eyes,
flush them with water .

Monitoring the
Advanced Airbag System
~i (USA models} / !f (Canada models}
Airbag monitoring indicator light
Two separate indicators monitor the function of
the Advanced Airbag System: the airbag moni­
toring indicator light and the
PASSENGER AIR
BAG OFF
light.
The Advanced A irbag System ( including the e lec­
tronic control unit, sensor circuits and system
wiring) is monitored continuously to make sure
that it is functioning properly whenever the igni­
tion is o n. Each time you turn on the ignit io n, the
airbag monitoring ind icator light
II (USA mod ­
e ls)
!E,I (Canada models) w ill come on for a few
seconds (self diag nostics).
The s ystem must be inspected when the
indicator light

(Canada models ):
- does no t come on when the igni tion is sw itched
on,
- does no t go out a few se co nds afte r yo u have
sw itched on the igni tion, or
- comes on while driv ing.
If an airbag system malfunction is detected, the
i ndicator light will come on to serve as a constant
r eminder to have the system inspected immedi­
ate ly.
If a ma lfunction occurs that turns the front air­
bag on the passenge r side off, the
PASSENGER
A IR BAG OFF
light will come on and stay o n
whenever the ignition is on.
A WARNING
A n a ir bag system t hat is not functioning prop­
e rly cannot provide sup plemental pro te ct ion
in a fronta l crash.
- If the airbag ind icator light¢ page 13
comes when the vehicle is being used, have
the system inspected immediately by your
author ized Audi dealer . It is possib le that
the airbag will inflate when it is not sup­ posed to, or will not inflate when it should.

Other things that can affect Advanced
Airbag performance
Changing the vehicle 's suspension system can
change the way that the Advanced Airbag System
performs in a crash . For e xamp le, using t ire -r im
comb inat io ns not approved by Audi, lower ing the
vehicle, chang ing the stiffness of the suspe nsion,
including the spr ings, suspension struts, shock
absorbers etc. can change the fo rces that are
measured by the airbag sensors and sent to the
electronic contro l unit. Some suspens ion changes
can, for example, increase the force levels meas­
ured 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 fo rce levels measured by
the sensors and prevent the airbag from deploy­ ing when it should .
162
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim comb inations can
change Advanced Airbag performance and in­
crease the r isk of serious personal injury i n a
crash.
- Never insta ll suspension components that
do not have the same performance charac­
ter istics as the components origina lly in stal­
led on you r vehi cle.
- N ever use tire-r im combinations that have
no t been approved by Aud i.
A WARNING
It ems stored between the safe ty belt buckle
and the cen ter conso le can cause the sensors
in the buckle to send the wrong information
to the electronic contro l module and prevent
the Advanced A irbag System from working

- Always make sure that nothing can interfe re
wit h the safety belt buckles and that they
are not obstructed.
Side airbags
Description of side airbags

protection to properly restrained occupants .
Fig. 168 S ide a irbag locatio n in the d river's seat
The side airbags a re located in the s ides of the
front seat backrests~
fig. 168 and the rear back­
rest * facing the doors . They are ident ified by the
word "AIRBAG".
The side airbag s ystem basically consi st s of :

-the e lectron ic control modu le and externa l side
impact sensors
- the two airbags located in the sides of the front
backrests and the two airbags * located in the
rear backrest
- the airbag warning light in the inst rument clus-
ter.
The a irbag system is monitored electronically to
make certa in that i t is functioning properly at all
times . Each time you turn on the ignition, the air­
bag system indicator light wi ll come on for a few
seconds (self diagnostics).
The s ide airbag system supp lements the safe ty
be lts and can help to reduce the risk of injury to
the driver 's and front passenger's upper torso on
the side of the vehicle that is struck in a side col­ lision . The airbag deploys on ly in side impacts
and only when the veh icle accelera tion reg istered
by the control unit is high enough . If this rate is
below the reference value programmed into the
control unit, the s ide airbags will not be tr ig­
ge red, even though the car may be badly dam­
aged as a result of the collision .
It is no t possib le
to define an airbag trigge ring range that w ill cov­
er every possible angle of impact, since the cir ­
cumstances wi ll vary considerably between one
collision and another. Important factors include,
for example, the nature (hard or soft) of the im­
pacting objec t, the ang le of impact , vehicle
speed , etc .
q page 164, Important safety in ­
structions on the side airbag system .
Aside from their normal safety function, safety
be lts work to help keep the driver or front pas­
senger in posit ion in the event of a side collision
so that the s ide a irbags can prov ide protection .
The airbag system is
not a substitute for your
safety belt. Rather, it is part of the overall occu­
pant restraint system in your veh icle . Always re ­
member that the s ide airbag system can only
h e lp to protect you if you are wea ring your safety
be lt and wea ring it p roperly. This is ano ther rea­
son why you s hou ld always wear yo ur safety
be lts, not just because the law requ ires yo u to do
so

It is important to remember that wh ile the sup­
p lement al side a irbag sys tem is designed to re-
Airb ag sys tem
duce the likelihood of serious injuries , other in ju­
ries, for example, swelling, bruising, and minor
abras ions can also be associated wit h deployed
s ide airbags. Remember too, s ide airbags will de­
ploy only once and only in certain k inds of acci­
dents -your safety belts are always there to offer
protect io n.
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessar ily an ind ication
of over -sens it ive or fa iled a irbag activation . In
some collisions, both front and side airbags may
inflate . Remember too, that a irbags w ill dep loy
o nl y once and only in certa in kinds of collisions -
yo ur safe ty belts are alw ays there to offer protec­
t ion in those accidents in which airbags are not
supposed to deploy or when they have already
deployed.
The side airbag system will not deploy:
- when the ignit io n is t urned off
- in side co llisions when the acceleration meas-
ured by the sensor is too low
- in fro nt-end coll is ions
- in rear-end collisions
- in rollovers .
In some types of accidents t he front airbags, side
curtain airbags and side ai rbags may be triggered
together .
A WARNING
--Safety belts and the airbag system will only
provide protect ion when occupants are in
the proper seat ing pos ition ¢

may interfere with side airbag deployment
and can cause personal injury in an accident .
- Always prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks.
- The airbag system can only be triggered
once . If the airbag has been triggered, the
system must be replaced by an authorized
Audi dealership .
- Damage (cracks, deep scratches etc.) to the

Child safety
Advanced Airbags and the weight-sensing mat in the front seat
The Advanced Airbag System in your vehicle de­
tects the presence of an infant or child in a child
restraint on the front passenger seat using the
weight -sensing mat in the seat cushion and the
sensor below the safety belt latch on the front
passenger seat that measures the tension on the
safety belt .
The weight-sensing mat measures total weight
of the child and the child safety seat and a child blanket on the front passenger seat . The weight
on the front passenger seat is related to the de­
sign of the child restraint and its "footprint ", the
size and shape of the bottom of the child re­
straint as it sits on the seat. The weight of a child
restraint and its "footprint" vary for different
kinds of child restraints and for the different
models of the same kind of child restraint of­
fered by child restraint manufacturers.
The weight ranges for the individual types,
makes and models of child restraints that the
NHTSA has specified in the Safety Standard to­
gether with the weight ranges of typical infants
and typical 1 year-old child have been stored in
the control unit of the Advanced Airbag System .
When a child restraint is being used on the front
passenger seat with a typical 1 year-old child, the
Advanced Airbag System compares the weight
measured by the weight sensing mat with the in­
formation stored in the electronic control unit.
The electronic control unit also registers the ten­
sion on the front passenger safety belt. The ten­
sion on the safety belt for the front passenger
seat will be different for an adult who is properly
using the safety belt as compared to the tension
on the belt when it is used to attach a child re­
straint to the seat. The sensor below the latch for
the safety belt for the front seat passenger
measures the tension on the belt. The input from
this sensor is then used with the weight to "de­
cide" , whether there is a child restraint with a
typical 1 year-old child on the front passenger
seat and whether or not the airbag must be
turned off.
170
· Child restraints and Advanced Airbags
Regardless of the child restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been certified by its manu­
facturer for use with an airbag. Always be sure
that the child restraint is properly installed at
one of the rear seating positions . If in exception­
al circumstances you must use it on the front passenger seat, carefully read all of the informa­
tion on child safety and Advanced Airbags and heed all of the applicable WARNINGS. Make cer­
tain that the child restraint is correctly recog­
nized by the weight-sensing mat inside the front
passenger seat, that the front passenger airbag
is turned off and that the airbag status is always
correctly signaled by the
PASSENGER AIR BAG
OFF
light.
Many types and models of child restraints have
been available over the years, new models are in­
troduced regularly incorporating new and im­
proved designs and older models are taken out of
production. Child restraints are not standardized.
Child restraints of the same type typically have
differen t weights and si zes and different 'foot­
prints,' the size and shape of the bottom of the
child restraint that sits on the seat, when they
are installed on a vehicle seat. These differences
make it virtually impossible to certify compliance
with the requirements for advanced airbags with
each and every child restraint that has ever been
sold in the past or will be sold over the course of
the useful life of your vehicle.
For this reason, the United States National High­
way Traffic Safety Administration has published a
list of specific type, makes and models of child
restraints that must be used to certify compli­
ance of the Advanced Airbag System in your vehi­
cle with the suppression requirements of Federal
Motor Vehicle Safety Standard 208. These child
restraints are:
