Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys
tem pe rforms in a crash. For example, us ing
tire-r im combinations not app roved by Aud i,
lowering the vehicle, changing the stiffness of
the suspension, incl uding 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
un it. Some suspension changes can, for exam
ple, increase the force levels measured by the
sensors a nd make the airbag system deploy in
crashes in w hich it would not dep loy 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 fo r the
d river and front passe nger 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 poss ible that an a irbag
will not deploy at a seating position whe re the
safety belt is being used but will inflate at the
position whe re the safety belt is not bei ng
used. It is important tha t noth ing inte rfe re
with the safety belt buckles so t hat the sen
sors can send the correct information a bout
safety belt use to the electronic contro l unit.
A WARNING
Changing the vehicle 's suspension includ
ing use of unapproved tire-rim c ombina
tions can change Advanced Airbag per
formance and increase the risk of ser ious
personal i njur y in a crash.
- Never install suspension components
that do not have the same performance characterist
ics as the components origi
na lly installed on your vehicle.
- Never use tire-rim com binations that
have not been approved by Audi.
A WARNING
= -
Items stored between the safety be lt
b uckle and the center console can cause
the sensors in the buckle to send the
wrong information to the e lectronic con
trol module and prevent the Advanced Air bag System from wo rking prope rly.
- Always make s ure that nothing can inter
fe re with the safety belt buckles and that
they are not obstructed.
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. 1 56 Dr iver 's k nee a irbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
Q fig . 156, the knee a irbag for the passenger
is at about the same height in the inst rument
pane l underneath the g love compar tme nt.
The knee airbag offers additional p rotection
to the driver 's and passenger's knees and up
per and lowe r th igh a reas and suppleme nts
the p rotec tion provided by t he safety be lts.
If the front a irbags dep loy, the knee a irbags
also dep loy in fron tal coll is io ns w hen the de
ployment th reshol d sto red in the control un it ..,,
is met c::> page 146, 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 subst itute 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 shou ld always wear your safety
belt, not just because the law requires you to
do soc::>
page 129, General notes .
The safety belt buckle for the driver and front
seat passenger 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 slightly higher
ra te of deceleration than if the belt is not be
ing used . Therefore, in a particu lar 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 be ing used.
Remember too, airbags will deploy only once
and only in certain kinds of accidents -your
safety belts are always there to offer protec
tion in those accidents in which airbags are
not supposed to deploy or when they have al
ready deployed, for example when your vehi
cle strikes or is struck by another after the
f ir st coll is ion.
This is just one of the reasons why an airbag is
not a substitute for the safety belt . The airbag
system works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correctly .
It is important to remember that while the
supplemental knee air bag system is des igned
to reduce the like lihood of serious injuries,
other injuries, for example, swelling, bruising,
and minor abras ions and frict ion burns can al
so occur when an airbag inflates.
Airbag system 153
The knee airbag system basically consists
of:
-The electronic control module
- Two inflatable airbags (airbag and gas gen- erator), one for the driver and one for the
front passenger
- The airbag indicator light in the instrument
panel
The knee airbag system will not deploy:
-when the ignition is turned off
- in frontal collisions when the deceleration
measured 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/indicator light is on) c::>
page 20.
A WARNING
-Safety belts and the airbag system can
only provide protection when occupants
are in the proper seating position
c::>
page 146.
-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.

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fi g. 158 S ide a irbag location i n the driver 's seat
The s ide a irbags are located in the sides of the
front sea t backrests
r=> fig . 158. They are iden
tified by the word "AIRBAG" .
The sid e a irbag system ba sicall y consis ts of :
-the electronic control module and external
side impact senso rs
- the two side airbags located in the sides of
the front backrests
- the a irbag warning 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 a irbag system supplements the safe
ty belts and can help to reduce the risk of in
jury to the dr iver's and front passenge r's up
pe r torso on the side of the veh icle that is
struck in a side co llision . The airbag deploys
on ly in side impacts and on ly when the vehicle
acceleration registered by the control u nit is
hi gh eno ugh . If this rate is below the refer
ence va lue programmed i nto the con trol 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
eve ry possible angle of impact, since the ci r
cumstances wi ll vary conside rably between
A irba g sy stem 155
one collis ion and anothe r. Important factors
incl ude, for example, the nature (hard or soft)
of the impacting object, the ang le of impact,
vehicle speed, etc.

safety instructions on the side airbag system .
Aside from their normal safety function, safe
ty belts work to help keep the driver or front

It is important to remembe r that wh ile the
s u pplementa l side airbag system is designed
to reduce the likelihood of ser ious inju ries,
other injur ies, for example, swelling, br uising,
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 the re to offer protection .
Vehicle damage, repair costs or
even the lack
of ve hicle damage are not necessarily a n indi
cation of over-sensitive or failed airbag activa
tion. In some coll is io ns, both front and side
airbags may inflate. Remember too, that air

Important safety instructions on the
side airbag system
Airbags are only supplemental restraints. Al
ways properly wear safety belts and ride in a
proper sea ting posi tion.
T he re is a lot that you and your passengers
must know and act accord ingly to help the
safety belts and airbags do their job to pro
vide supplementa l protectio n.
.&_ WARNING
-An inflat ing s ide a irbag can cause serious
or fata l injury . Improperly wearing safety
belts and imp roper seating pos it io ns in
crease the risk of se rious pe rsonal injury
and dea th whenever a vehicle is being
used.
- In or der to reduce the risk of in ju ry when
t he supplemental side airbag infl ates :
- Always sit in an upright position and
never lean against the area where the
suppleme nta l side airbag is located.
- Never let a child or anyone e lse rest
their head aga inst the s ide trim pane l
i n the area where the supplementa l
s ide airbag inflates .
- Always make sure that safety be lts a re
worn correctly,
- Do not let anyone s itting in the fr ont
seat put t heir hand or any ot her parts
of their body out of the window .
- Always make sure that the s ide airbag
can inf late without interfe rence .
-If you must install a rearward facing
child safety seat on the front passenger
seat in exceptional circumstances and
the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately
install the rearward-facing child safety
seat in a rear seating position and have
the airbag system inspected immediately by your authorized Audi dealer.
,& WARNING
If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Always follow the manufacturer's in
structions provided with the child safety
seat or carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the child restraint. The backrest must be adjusted to an upright position .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
@ Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad
vanced Airbag System" in compliance with
United States Federal Motor Vehicle Safety
Standard (FMVSS) 208 as applicable at the
time your vehicle was manufactured .
Child Safety 159
The Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re
quirements for 3- and 6-year old children on
the passenger side and small adults on the driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that can
occur, for example, by being too close to the
steering wheel and instrument panel when
the airbag inflates. In addition, the system
has been certified to comply with the "sup
pression" requirements of the Safety Stand
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front passenger seat in child restraints that are list
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe
cially those 12 years and younger, should al
ways ride in the back seat properly restrained
for their age and size . The airbag on the pas
senger side makes the front seat a potentially
dangerous place for a child to ride . The front
seat is not the safest place for a child in a for
ward-facing child safety seat. It can be a very
dangerous place for an infant or a larger child
in a rearward-facing seat.
Advanced Airbags and the weight
sensing mat in the front seat
The Advanced Airbag System in your vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us
ing the weight-sensing mat in the seat cush
ion 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 design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the
seat. The weight of a child restraint and its "footprint" vary for different kinds of child re -
straints and for the different models of the ..,. •

Child safety seats
Infant seats
Babies and infants up to about one year old
and 20 lbs. or 9 kg need special rearward-fac
ing child restraints that support the back,
neck and head in a crash.
-- /
Fig . 161 Sche matic overview: rearward- facing infant

> Secure unused safety belts on the rear seat
¢page 163.
Infants up to about one year (20 lbs. or 9 kg)
are best protected in special infant carriers
and child safety seats designed for their age
group . Many experts believe that infants and
small children should ride only in spec ial re
straints in which the chi ld faces the back of
the vehicle . These infant seats support the ba
by's back, neck and head in a crash ¢
fig. 161 .
The airbag on the passenger side makes the
front seat a potentially dangerous place for a
child to r ide . The front seat is not the safest
p lace for a child in a forwa rd-facing child seat.
I t is a very dangerous p lace for an infant or a
larger child in a rearward-facing seat.
A WARNING
-Not using a child safety seat, using the
wrong child safety seat or improperly in
stalling a ch ild restra int increases the risk
of ser ious personal in ju ry and death in a
crash.
- Never install rearwa rd-facing child safety
seats or infant ca rr ie rs on the front pas
senger sea t -even with an Advanced Air
bag Sys tem. A c hild will be ser iously in
jured and can be killed whe n the inflat
