Monitoring the
Advanced Airbag
System
Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System: the airbag
monitoring indicator light and the
PAS SEN
GER AIR B AG OFF
light.
The Advanced Airbag System (including the
e lectronic control unit, sensor circuits and sys
tem wiring) is monitored continuously to
make sure that it is functioning properly
whenever the ignit ion is on . Each t ime you
turn on the ignition, the
I airbag monitoring
i ndicator light w ill come o n for a few seconds
(self diagnostics) .
The system mu st be in spected when the
I indicator l ight:
- does not come on when the ignit ion is
switched on,
- does not go out a few seconds after yo u
have switched on the ignition, o r
- comes on while d riving .
If an airbag system malfunction is detected,
the indicator light will first start flashing to
catch the driver's attention and then stay on
continuously to serve as a constant reminder
to have the system inspected immediately.
If a malfunction occurs that turns the front
a irbag on the passenger side off, the
PASSEN
GER AIR BAG OFF
li ght will come on and stay
on whenever the ignition is on.
_& WARNING
An airbag system that is not funct ioning
properly cannot provide supp lemen tal p ro
tection in a frontal crash .
-If the airbag indicator l ight c::> page 20
comes whe n the vehicle is be ing used,
have the system inspected immediately
by yo ur authorized Audi dea ler .
It is pos
sible that the airbag will inflate when it
is not supposed to, or w ill not inflate
when it should.

The knee airbag system has been designed so
that the airbags for the driver and front pas
senger deploy in certain but not all frontal
collis ions .
I f the front airbags deploy , the knee airbags
also deploy in fronta l collis ions when the de
p loyment threshold stored in the control unit
is met .
When the system dep loys, the airbags fill
with a prope llant gas, and inflate between the
l ower part of the instrument panel and the
driver and the lower part of the instrument panel and the fron t passenger
c> page 151 ,
fig . 14 2.
Although they are not a soft pillow, they can
cushion the impact and in this way they can
he lp to reduce the r isk of injury to the lower
extremities .
All of this takes place in the blink of an eye, so
fast that many people don't even reali ze that
t he airbags have deployed . The airbags also
inflate w it h a great deal of force and it is im
portant for occ upant safety that not hing
should be in the ir way when they dep loy .
Fully infla ted airbags in comb ination with
properly worn safety belts slow down and lim
it the occupant's forward movement and help
to reduce the r isk of injury .
Important safety instructions on the
knee airbag system
Applies to vehicles: with knee a irbags
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 passenge rs
must know and do to help the safety be lts a nd
ai rbags to provide supp lemen tal protection .
_.6 WARNING
An inflating knee airbag can cause ser ious
injury. Wear ing safety belts incorrectly and
improper seating positions increase the
r isk of serious personal injury and death
whenever a veh icle is being used.
A irbag system 159
-The knee a irbag system cannot p rotect
you proper ly if you a re seated too close
to any of the airbag locat ions. When ad
justing their seat pos itions, it is impor
tant that both the driver and the front passenger keep the ir upper bod ies and
knees at the following m inimum 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 in jury increases if
you lean forward or to the s ide, or if the
seat is improperly positioned and you are
not wearing yo ur safety belt . The risk i n
creases even more should the ai rbag de
ploy .
- Always ma ke sure that the knee a irbag
can inflate without inte rfe rence. Objects
between yo u and the airbag can inc rease
the risk of in jury in an accident by inte r
fering w ith the way the a irbag deploys or
by being p ushed into you as the airbag
deploys.
- Never let anybody, especia lly children
or anima ls ride in the footwell in front
of the passenge r seat. If the airbag de
ploys, th is can result in serious or fa tal
i njur ies.
- Never carry obje cts of any kind in the
footwe ll area in front of the dr iver' s or
passenger 's sea t. Bulky objects (shop
ping bags , fo r example) can interfere
with o r prevent proper deployment of
the airbag. Small objects can be
thrown through the ve hicle 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 ch ildren are incorrectly seated, their
risk of injury increases in a collision

- 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

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

& 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.
164 Airbag system
How side curtain airbags work
Side curtain airbags can work together with
side airbags to help reduce the risk of head
and upper torso injuries for occupants who
are properly restrained.

Child Safety
Important things to
know
Introduction
The rear seat is generally the safest place in a
collision .
The physical principles of what happens when
your veh icle is in a crash app ly also to chi ldren
q page 135, What happens to occupants not
wearing safety belts? .
But unlike adults 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 deve l
oped, they require restra int systems especial
l y designed for their size , weight, and body
structure. Many countries and all states of the United States and p rovinces 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 ch ild restraint properly
used can reduce the risk of serious injury.
Ch ild restra ints must be used properly to be
effective. Used improperly, they can increase
the risk of serious injury in an accident .
Consult the child safety seat manufactu rer's
instructions to be sure the seat is right for
your chi ld's size
q page 169, Important safe
ty instructions for using child safety seats .
Please be sure to read and heed all of the im
portant information and WARNINGS about
child safety, Advanced Airbags, and the instal lation 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 manua l 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
- Accident statistics have shown that chil
dren are generally safer in the rear seat
area than in the front seating position.
Always restrain any child age 12 and un
der in the rear.
- All vehicle occupants and especially chil
dren must be restrained properly when
ever riding in a vehicle. An unrestrained
or improperly restrained chi ld could be
injured by str ik ing the interior or by be
ing ejected from the vehicle dur ing a
sudden maneuver or impact. An unre
strained or improperly restrained ch ild is
also at greater risk of injury or death
through contact with an inflating airbag.
- A suitable child restraint properly instal
led and used at one of the rear seating
positions provides the highest degree of
protection for infants and small children
in most accident situations.
A 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 w ill be ser iously injured and can
be killed if the front airbag inflates.
- The inflating airbag will h it the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the back rest, center
armrest or door .
- Always install rearward-facing child safe-
ty seats on the rear seat.
IJi,,,
-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 167
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 ..,. •
•
168 Child Saf ety
same kind of child rest raint offered by child
restraint manufact urers.
The weight ranges fo r the ind ividual types,
makes and mode ls o f chi ld restra ints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in
fants and typical 1 year-o ld child have been
stored in the control unit of the Advanced A ir
bag System. When a child restraint is being
used on the front passenger seat with a typi
cal 1 year-old ch ild, the Advanced Airbag Sys
tem compa res the we ight measured by the
weight sensing mat with the informat io n sto r
ed i n the ele ct ron ic cont ro l uni t.
The electron ic control unit also registers the
tension on the front passenge r safety belt .
The tens io n on the safety be lt fo r the front
passenger seat will be d iffe ren t for an ad ult
who is prope rly using the safety belt as com
pared to the tension on the be lt whe n it is
used to attach a chi ld restraint to the seat.
The sensor below the latch for the safety be lt
for the front seat passenger meas ures the
tension on the be lt. The input from this sen
sor is then used with the we ight to "decide",
whether there is a ch ild restraint w ith a typ ical
1 year-o ld child o n the front passenger seat
and whe ther or not the ai rbag must be tu rned
off.
Child restraints and Advanced Airbags
Regardless o f the child restraint t hat you use,
make sure that it has been ce rtified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu
facturer for use with a n airbag. Always be sure
that the child restraint is properly instal led at
one of the rear seat ing pos itions .
If in excep
tional c ircumstances you must use it on the
fro nt passenger sea t, caref ully read all of the
i n format ion on c hild safety and Advanced A ir
bags and heed a ll of the app licab le WAR N
I NGS . Ma ke certain that the child restraint is
correctly recognized by the weig ht-sensing
mat inside the front passenger seat, that the
fro nt passenger airbag is turned off and that the a
irbag sta tus is always cor rect ly signa led
by the
PASSENGER AIR BAG OFF light .
Many types and models of child res traints
h ave been available over the yea rs, new mod
els are introduced regu larly incorporating new
and improved designs and o lde r mode ls are
ta ken out o f product ion . Ch ild restra ints are
not standard ized . Child restraints of the same
type typically have different weights and sizes
and different 'footpr ints,' the size and shape
of the bottom of the ch ild restra int that sits
on the seat, when they are insta lled on a vehi
cl e seat. These d iffe rences make it v irtually
i mpossible to certify compl ian ce wi th t he re
quiremen ts for advanced airbags with eac h
and every chi ld restraint that has eve r been
sold in the past or wi ll be sold over the course
of the useful life of your veh icle.
F or t his reason, the United S tates National
Highway T raffic Safety Adm inist ration has
published a list of specific type, ma kes and
models of child restraints that must be used
to certify comp liance of the Advanced Airbag
