This is just one o f the reasons why an a irbag is
not a substitute for the safety belt . The airbag
system works most effective ly when used wit h
the safety belts. Theref ore, always wear your
safety belts correctly .
It is important to remember that while t he
supp lemental knee a irbag system is des igned
to reduce the like lihood of serious injur ies,
other injuries, for example, swel ling, bruising,
minor abrasions and friction burns can also
occur when a n airbag inflates .
The knee airb ag sy stem ba sically con sist s
of:
-The electronic contro l modu le
- 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 d eploy :
-when the ignition is turned off
- in frontal col lisions when the dece lerat ion
measured by the contro l unit is too low
- in s ide coll isions
- in rear-end colli sions
- in ro llovers
- in the event of a system malfunct ion (warn-

How knee airbags work
The risk of injury to the leg area can be re
duced by fully deployed knee airbags.
F ig. 1 22 In flated a irbags protect ing in a frontal colli
s io n
The knee airbag system has been designed so
that the airbags for the driver and fro nt pas
senger deploy in certain but not all frontal
collisions .
If the front a irbags dep loy, the knee a irbags
also deploy in frontal col lisions when the de
ployment threshold sto red in the control unit
is met.
When the system deploys fill the airbags with
a p ropellant gas, and inflate between the low
er part of the instrume nt pane l and the dr iver
and the lower part of the instr ument pane l
and the front passe nger
~ page 120, fig. 119.
Although they are not a soft pillow, they can
"cushion" the impact and in th is way they can
help to reduce the risk of injury to the lower
extremit ies.
All of th is takes place in the bli nk of an eye, so
fast that many people don't even realize that
the a irbags have deployed. The airbags a lso
inflate wi th a g reat dea l of fo rce and it is im
po rtant for occup ant safety t hat no thing

Fully inflated ai rbags in combination with
properly worn safety be lts s low dow n and lim

128 Airbag system
Important safety instructions on the
knee airbag system
Airbags are only supplemental restraints. Al
ways wear safety belts correctly and ride in a
proper seating position.
There is a lot that you and your passenger
must know and do to help the safety belts and
airbags to provide supplemental protection.
.&_ WARNING
An inflating knee airbag can cause serious injury. Wearing safety belts incorrectly and
improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
-
- The knee airbag system cannot protect
you properly if you are seated too close
to any of the airbag locations. When ad
justing their seat positions, it is impor
tant that both the driver and the front
passenger keep their upper bodies and
knees at the following min imum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru
ment panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru
ment panel.
- The risk of personal injury increases if
you lean forward or to the side, or if the
seat is improperly positioned and you are
not wearing your safety belt. The risk in
creases even more should the airbag de
ploy.
- Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter
fering with the way the airbag dep loys or
by being pushed into you as the airbag
deploys .
- Never let anybody, especially children
or animals in the footwell in front of
the passenger seat.
If the airbag de- ploys, this can result in serious or fatal
injuries.
- No objects of any kind should be car
ried in the footwell area in front of the
driver's or passenger's seat. Bulky ob
jects (shopping bags, for example) can
hamper or prevent proper deployment
of the airbag . Small objects can be
thrown through the vehicle if the air bag deploys and injure you or your pas
sengers.
- Make sure there are no cracks, deep
scratches or other damage in the area of
the instrument panel where the knee air
bags are located.
- If children are incorrectly seated, their
risk of injury increases in a collision
~page 132, Child Safety.
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants.
Fig. 123 S ide a irbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests
q fig. 123 facing the
doors. They are identified by the word "AIR
BAG".
Th e side airbag system basically consists of:
-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 .
Page 131 of 244

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 side airbag system supp lements 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 and head injuries on the side of the
ve hicle that is st ruck in a side co llision . The
airbag deploys in s ide impacts and only when
the veh icle acce lerat ion registered by the con
trol un it is high enough. If this rate is below
the refe rence va lue p rogrammed into the con
trol un it, the s ide a irbags w ill not be trig
gered, even though the car may be bad ly dam
aged as a result of the collision . It is not pos
sib le to define an airbag tr igger ing range that
will cover every poss ible angle of impact,
since the c ircumstances will vary considerab ly
between one collision and anothe r. Important
factors include, fo r example, the nature (hard
or soft) of the impacting object, the angle of i mpa ct, veh icle speed, e tc.¢

portant safety instru ctions on the side airbag
system .
Aside from the ir normal safety function, safe
ty belts wor k to he lp keep t he d river or front
passenger in posi tion in the event of a side
coll is ion so that the side a irbags can provide
p rotection.
The airbag sys tem is
not a subs titute for your
safety be lt. R athe r, it is pa rt of the overall oc
cupant res traint system in your veh icle . Al
ways remember that the side airbag system
can only he lp to protect you if you are wearing
your safety belt and wear ing it properly. Th is
is another reason w hy you sho uld always wear
your safety belts, not just because the law re
qu ires you to do so¢
page 103, General
notes.
It is important to remember that while the
supp lemental s ide a irbag system is designed
to reduce the like lihood of serious injur ies,
other i njuries, for example, swell ing, b ruising,
and minor abras ions can also be assoc iated
with deployed s ide a irbags . Remem ber too,
A irbag system 129
side airbags wi ll dep loy only once and only in
certain kinds of accidents -your safety belts
are always the re to offer p rotection.
Vehicle damage, repair costs or even t he lack
of ve hicle damage are not necessarily an indi
cation of over-sensitive or failed airbag activa
tion . In some coll is ions, both front and side
airbags may inflate. Remember too, that air bags will deploy only once a nd only in certain
k inds of col lisions -your safety be lts a re al
ways the re to offe r protection in those acc i
dents in which airbags are not supposed to
deploy or when they have a lready deployed .
The side airbag system will not deploy:
-when the ignit io n is turned off
- in side co llisions when the acceleration
meas ured by the sensor is too low
- in rear-end co llisions
- in rollove rs .
In some types of ac cidents the front airbags
and s ide a ir b ag s may be triggere d toge ther.
A_ WARNING
- Safety belts and the airbag system wi ll
only provide protection when occupants
are in the proper seating position
¢page 130.
-If the ai rbag indicator light comes on
when the vehicle is being used, have the
system inspected immediately by your
author ized Audi dealer. The airbag may
not work properly when the vehicle ac
c e leration in a side collis ion is high
e nough to activate t he a irbag. •

130 Airbag system
How supplemental side airbags work
Side airbags deploy instantly and con help re
duce the risk of upper torso injuries for occu
pants who ore properly restrained.
Fi g. 1 24 Inflated s ide airbags on left side of vehicle
When the system is triggered, the airbag is
filled with prope llant gas and breaks through
a seam in the seat surface area marked "AIR
BAG". It expands between the side trim pane l
and the passenger . In order to help provide
this additional protection, the side airbag
must inflate within a fraction of a second at
very hig h speed and with great force. The sup
plemental side airbag could i njure you if your
seating position is no t proper or upr ight or if
items are located in the area where the sup
p lemental side airbag expands. This applies
especial ly to children

ty.
Supplementa l side airbags inflate between
the occupant and the door pane l on the side

Q fig . 124.
A lthough they are not a soft pillow, they can
"cushion" the impact and in th is way they can

part of the body.
A fine dust may develop when the airbag de
p loys. This is norma l and does not mean there
is a fire in the vehicle. Important safety instructions on the
side airbag system
Airbags ore only
supplemental restraints. Al
ways properly wear safe ty belts and ride in a
proper seating position.
The re is a lot that you and your passenger
must know and act accord ingly to help the
safety belts and airbags do their job to pro
vide supplementa l protect ion .
A WARNING
An inflating side ai rbag can cause serious
or fata l injury. Improperly weari ng 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 inj ury when
the supplemental side airbag inflates:
- Always sit in an upright posi tion and
never lean aga inst the area whe re the
s u ppleme nta l side air bag is located .
- Never let a child or a nyone e lse rest
t h eir head aga inst the s ide trim pane l
in the area where the supplementa l
side airbag inflates.
-Always make sure tha t safety be lts a re
worn correctly,
- Do no t let anyone s itting in the fron t
seat put t heir hand or any ot her parts
of their body out of the win dow.
-Always make sure that the side airbag can inflate without interference.
- Neve r install seat covers or rep lace
ment upholstery over th e front seat
backs that have not been specifically
approved by Audi.
- Neve r use additional seat c ushions that
cove r the areas where the side a irbags
deploy.
- Damage to the orig inal seat cove rs or
to t he seam in the area of the si de a ir
bag module mus t always be repaired
i mmediately by a n author ized Audi
dealer.
Page 133 of 244

-Objects between you and the airbag can
increase the risk of injury in an accident
by interfering with the way the airbag
unfolds or by being pushed into you as
the airbag inflates .
- Never place or attach accessories or
other objects (such as cup holders, tel
ephone brackets, or even large, bulky
objects) on the doors, over or near the
area marked "AIRBAG" on the seat
backrests.
- Such objects and accessories can be
come dangerous projectiles and cause
injury when the supplemental side air
bag deploys .
- Never carry any objects or pets in the
deployment space between them and
the airbags or allow children or other
passengers to travel in this position.
-Always prevent the side airbags 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 airbag has been triggered,
the system must be replaced by an au
thorized Audi dealership.
- Damage (cracks, deep scratches etc.) to
the original seat covers or to the seam in
the area of the side airbag module must always be repaired 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 132, 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 air pressure in
side the doors when air escapes through
larger, unclosed openings in the door
panel.
- Never drive with interior door trim pan
els removed.
- Never drive when parts have been re
moved from the inside door panel and
Airbag system 131
the openings they leave have not been
properly closed.
- Never drive 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 additional speakers
or other equipment is installed in the inside door panels.
- Always have work on the doors done by
an authorized Audi dealer or qualified
workshop.

132 Child Safety
Child Safety
Important things to know
Introduction
The physical principles of what happens when
your vehicle is in a crash apply also to children
c::> page 104, What happens to occupants not
wearing safety belts? .
But unlike adults and
teenagers, their muscles and bones are not
fully developed . In many respects children are
at greater risk of serious injury in crashes than
adults.
Because children's bodies are not fully devel
oped, they require restraint systems especial
ly designed for their size, weight, and body
structure . Many countries and all states of the
United States and provinces of Canada have
laws requiring the use of approved child re
straint systems for infants and small children.
In a frontal crash at a speed of 20-35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infant will be more than 20 times the
weight of the child. This means the weight of
the child would suddenly be more than 260 pounds (120 kg). Under these conditions,
only an appropriate child restraint properly used can reduce the risk of serious injury.
Child restraints, like adult safety belts, must
be used properly to be effective. Used improp
erly, they can increase the risk of serious in
jury in an accident.
Consult the child safety seat manufacturer's instructions in order to be sure the seat is
right for your child's size
c::> page 135, Impor
tant safety instructions for using child safety
seats.
Please be sure to read and heed all of
the important information and WARNINGS
about child safety, Advanced Airbags, and the
installation of child restraints in this chapter.
There is a lot you need to know about the Ad
vanced Airbags in your vehicle and how they
work when infants and children in child re
straints are on the front passenger seat. Be
cause of the large amount of important infor- mation, we cannot repeat it all here. We urge
you to read the detailed information in this
owner's manual about airbags and the Ad
vanced Airbag System in your vehicle and the
very important information about transport ing children on the front passenger seat.
Please be sure to heed the WARNINGS - they
are extremely important for your safety and
the safety of your passengers, especially in
fants and small children.
A WARNING
-
All vehicle occupants and especially chil
dren must be restrained properly whenev
er riding in a vehicle. An unrestrained or
improperly restrained child could be in
jured by striking the interior or by being
ejected from the vehicle during a sudden maneuver or impact. An unrestrained or
improperly restrained child is also at great
er risk of injury or death through contact
with an inflating airbag.
_& WARNING
Children on the front seat of any car even
with Advanced Airbags can be seriously in
jured or even killed when an airbag in
flates. A child in a rearward-facing child
safety seat installed on the front passen
ger seat will be seriously injured and can
be killed if the front airbag inflates.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, door or roof.
- Never install a rearward facing child
safety seat on the front passenger seat
unless the
PASSENGER AIR BAG OFF
light comes on and stays on. If the PAS·
SENGER AIR BAG OFF
light does not
come on and stay on, have the airbag
system inspected immediately by your
Audi dealer.
.

A 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 an "Advanced
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
Child Safety 133
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, a child should al
ways ride in the seat properly restrained for
its age and size . The airbag on the passenger
side makes the front seat a potentially dan
gerous place for a child to ride. The front seat
is not the safest place for a child in a forward
facing child safety seat .
It can be a very dan
gerous 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
same kind of child restraint offered 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
together with the weight ranges of typical in
fants and typical 1 year-old child have been
stored in the control unit of the Advanced Air
bag System. When a child restraint is being
used on the front passenger seat with a
ll-
•
•

134 Child Saf ety
typical 1 year -old chi ld, the Advanced Airbag
System compares the weight meas ured by the
weight sensing mat with the in format ion stor
ed in the electron ic contro l unit.
The electron ic contro l unit a lso registers the
tension on the front passenge r safety belt.
The tens ion on the safety be lt fo r the front
passenger seat will be d ifferent for an adult
who is properly using the safety belt as com
pared to the tension on t he be lt whe n it is
used to attach a child restraint to the seat.
The senso r below the latch fo r the safety be lt
fo r the front seat passenger measu res the
tension on the be lt. T he inp ut from this sen
sor is then used with the we igh t to "decide",
whether there is a chi ld restraint with a typica l
1 year-o ld child o n the front passenger seat
and whether or not the airbag must be turned
off.
Child restraints and Advanced Airbags
Regardless of the ch ild restraint that you use,
make sure tha t it has been ce rtified to meet
Un ited States Fede ral Motor Vehicle Safety
S tanda rds a nd has been cer tified by its manu
facture r fo r u se wit h an air bag. If i n excep
tional circumstances yo u m ust use it on the
front passenge r seat, caref ully read all of the
info rmation on c hild safety an d Advanced Air
bags and heed a ll of the app licable WARN
INGS. Make certai n that t he child restraint is
correctly recognized by the weig ht-sensing
mat i nside the front passenger seat, that the
fro nt passenge r airbag is tur ned off and that
the airbag status is a lways correctly signaled
by the
PASSENGER AIR BAG OFF light .
Many types and models of child restra ints
have been ava ilable over the years, new mod
e ls ar e introduced regularly incorporat ing new
a nd improved designs a nd older models are
taken out of p ro du ction. Child res traints are
not stan dardized . Ch ild restra ints o f the same
type typically have different weights and s izes
a nd d ifferent 'footprints,' the s ize and s hape
of the bottom o f the child restraint that sits
on the seat, when they are installed on a veh i
cle seat. These differences make it virtually impossible to certify compliance wi
th t he re
quirements for a dvanced airbags with eac h
and every ch ild restra int that has ever been
sold in the past or wi ll be sold over the course
of the useful life of your veh icle.
For t his reason, the United States National
Hig hway T raffic Safety Adm inistrat ion has
