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)

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

when i t should.
How knee airbags work
App lies to vehicles: with knee airbags
The risk of injury to the l eg area can be re­
duced by fully deployed knee airbags.
Fi g. 1 55 Inf lated ai rbags protect ing in a frontal colli­

How supplemental side airbags work
.
Side airbags deploy ins tan tly and can help re­
duce the risk of upper torso injuries for occu ­
pants who are properly restrained .
Fig. 15 7 Infla ted s ide a irbag s on left s ide of ve hicle
When the system is trigge red , the airbag is
fi lled w ith p ropel lant gas and breaks thro ugh
a seam in the seat surface area marked "AIR­
BAG" . It expands between the side trim panel
and the passenger. In orde r to help provide
t his additional protection, the side a irbag
must inf late within a fraction of a second at
very high speed a nd with great force . The sup ­
p lemental side a irbag could injure you if your
seating position is not p roper or upr ight or if
items are located in the area where the sup ­
p lemental side a irbag expands . T his app lies
especia lly to children

Although they are no t a soft pillow , they can
"cushion" the impa ct 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 . T his is normal and does no t 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 r ide in a
proper sea ting position.
T here is a lot that you and your passengers
must know and act accord ingly to help the
safety belts and airbags do the ir job to pro­
vide supplemental protect ion.
A WARNING ,-
An inflat ing s ide a irbag can cause se rious
or fata l injury . Improperly wearing safety
belts and imp roper seat ing pos itions in­
crease the risk of serious pe rsonal injury
and death whenever a vehicle is being
used.
- I n o rder to red uce the risk of i nju ry when
the s upplemental side airbag inflates:
- 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 a irbag inflates .
- Always make sure that safety belts are
worn correctly,
- Do not let anyone s itting in the front
seat put t he ir hand or any ot her parts
of their body out of the window .
- Always make su re t hat the side a irbag
can inflate without interfe rence .

162 Child Safety
-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.
(D 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 . 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 . 159 Sche matic overv iew: rearward-fac ing infant

~ Secure unused safety belts on the rear seat
¢page 166.
Infants up to about one year (20 lbs . or 9 kg)
are best protected in special infan t 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 ch ild faces the back of
the vehicle. These infant seats support the ba­
by's back, neck and head in a crash
¢fig . 159.
The airbag on the passenger side makes the
front seat a po tentially dangerous place for a
child to r ide . The front seat is not the safest
p lace for a child in a forward -facing child seat.
It is a very dangerous p lace for an infant or a
l arger ch ild in a rearward-facing seat.

The airbag on the passenger side makes the
front seat a potentia lly dangerous place for a
c h ild to ride. The front seat is not the safest
place for a child in a forward-facing child safe­
ty seat. It is a very dangerous place for an in­
fant or a larger ch ild in a rearward-facing seat.
A WARNING c=
Not using a child safety seat, us ing the
wrong child safety seat or imprope rly in­
stalling a ch ild restra int increases the risk
of ser ious personal in jury and death in a
