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
G ER 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 on 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 driving .
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
airbag 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 when the vehicle is be ing used,
have the system inspected immediately
by your 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 collisions 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 front passenger
c> fig. 152.
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 realize that
the airbags have deployed. The airbags also inflate w ith a great deal of force and it is im
portant for occupant safety that noth ing
should be in the ir way when they deploy .
Fu lly inflated 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
A ppl ies 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 passengers must know and do to help t he safety belts and
ai rbags to provide supp lemental p rotection .
_& WARNING
An inflating knee airbag can c ause ser ious
injury. Wear ing safety belts inco rrectly and
improper seating positions increase the
ris k of se rious personal injury and death
whenever a veh icle is being used.
A irbag system 157
-The knee a irbag system cannot p rotect
you proper ly if you a re seated too close
to any of the a irbag 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
dist ances:
- 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 acc ident 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

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

- 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

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 133, What happens to occupants not
wearing safety belts? .
But unlike adu lts thei r
muscles and bones are not fully developed. In
many respects children are at greater risk of
serio us inju ry in crashes than adults .
Because children's bod ies are not fu lly deve l
oped, they require restraint systems especial
l y des igned for their size, weight, and body
structure. Many co untries and all states of th e
United States and p rovinces of Canada have
laws requ iring the u se of approved ch ild re
straint systems for infants and small children .
In a frontal crash at a speed o f 20 -35 mph
(30-56 km/h) the forces acting on a 13-po und
(6 kg) infant w ill be more than 20 t imes the
weight of the child . Th is means the weight of
the child would suddenly be more than
260 pounds ( 120 kg). Under these conditions,
on ly an appropriate chi ld restrai nt properly
used can reduce the risk of ser ious injury.
Ch ild restr aints must be used p roperly to be
effective. Used improperly, they can inc rease
the risk of serious in jury i n an accident.
Consult the chil d safety seat manufacture r's
i nstr uctions to be s ure the seat is r igh t for
your chi ld's size
q page 164, Important safe
ty instructions for using child safety seats .
Please be sure to read and heed a ll of the im
portant informat ion and WARNINGS abo ut
child safety, Advanced Airbags, and the ins tal
lation of child restraints in this chapter.
T here is a lot you need to know about the Ad
vanced A irbags 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 i nfor-
Child Sa fet y 161
mation, we cannot repeat it a ll here . We urge
you to read the detai led information in this
owner 's man ua l about airbags and the Ad
vanced Airbag System in your vehicle and the
very important information about transpor t
ing ch ildren on the front passenger seat.
Please be sure to heed the WARNINGS -they
ar e extremely importa nt for your safety and
the safety of you r passenge rs, especially in
f an ts and small chi ld ren.
A WARNING
- Accident statistics have shown that c hil
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 p roperly when
ever riding i n a vehicle. An unrestrained
or improper ly restrained chi ld could be
in ju red by str iking the interior o r by be
ing ejected from the vehicle during a
sudden maneuve r or impact. A n un re
s tra ine d or improperly restrained ch ild is
a lso at greate r risk of injury o r dea th
through contact with an inflating airbag .
- A suitable ch ild restrai nt properly inst al
led and used a t one o f the rear seat ing
positions prov ides 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 ser iously in
ju red or even killed when an a irbag i n
flates. A child in a rearward -fac ing ch ild
safety seat installed on t he front passen
ger seat w ill be ser iously injured and can
be killed if the front airbag infla tes.
- The infla ting airbag will h it the ch ild
s afe ty seat or i nfant carrie r wi th grea t
force and will sm ash the child safety se at
and child against the bac krest or doo r.
- Always install rearward-faci ng ch ild safe
t y seats on the re ar seat.

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 .,.
same kind of child restrain t offered by child
restraint manufacturers.
T he weight ranges for the ind iv idual types,
makes and models o f ch ild restra ints tha t 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 compares the we ight measured by the
weight sens ing mat with the info rmat ion s to r
ed i n the electron ic cont rol unit.
The electron ic control unit a lso registers the
tension on the front passenger safety be lt.
The te nsio n on the safety be lt fo r the front
p assenger seat will be d iffe ren t fo r an ad ult
who is properly using the safety belt as com
pared to the tension on the be lt when it is
used to attach a child restraint to the seat.
The sensor below the latch for the safety be lt
for the front seat passenger measures 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 restrai nt with a typ ical
1 year-o ld child on the front passenge r seat
and whether or no t the airbag must be turned
off.
Child restraints and Advanced Airbags
Regard less o f the child res traint that 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 an airbag. Always be sure
that the child restraint is properly insta lled at
one of the rea r seat ing pos itions .
If in excep-
tional c ircumstances you must use it on the
fr ont passenge r seat, caref ully read all of the
i n formation on c hild safety and Adv ance d Air-
b ags an d heed a ll of the app licable WAR N-
I NGS . Ma ke certai n 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
Child Sa fet y 163
the a irbag s tat us is always cor rect ly signaled
by the
PASSENGER AIR BAG OFF light .
Many types and models of child res traints
have been available over t he years, new mod
els are introduced regu larly incorporating new
and improved designs and o lde r models are
ta ken o ut of product ion . Ch ild restraints are
not standard ized. Child restraints of the same
type typically have d ifferent 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 a re insta lled on a vehi
cl e sea t. T hese d iffe rences make i t vir tually
i mpossible to certify compl iance wi th t he re
quiremen ts for advanced airbags with each
and every ch ild 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.
For t his reason, the United S tates Na tional
Hig hway T raffic Safety Administration has
published a list of specific type, makes and
models of child restraints that must be used
to certify comp liance of the Advanced Airbag
System in your veh icle with the suppression
requirements of Federal Motor Vehicle Safety
Standard 208. These child res traints are:

(!) Tips
The child seats listed in categories A to C have been statically tested by Audi on ly for
the Advanced A irbag function.
Important safety instructions for using
child safety seats
Correct use of child safety seats substantially
reduces the risk of injury in an accident!
As the driver, you are responsib le for the safe
ty of everybody in the veh icle, especially ch il
dren:
... Always use the right chi ld safety seat for
each child and always use it properly
c::;,page 167 .
... Always carefully fo llow the child safety seat
manufacturer's instruct ions on how to route
the safety belt properly through the child
safety seat.
... When using the veh icle safety belt to install
a child safety seat, you m ust first activate
the convertib le locking retractor on the
safety belt to prevent the child safety seat
from moving
¢ page 171.
... Push the ch ild safety seat down with your
full weight to get the safety be lt really tight
so that the seat cannot move forwa rd or
sideways mo re than one inch (2.5 cm) .
... If a strap o r tether is be ing used to tie the
child safety seat to the front passenger
seat, make sure tha t it i s n ot so tight th at i t
causes the weight -sensing mat to measure
more weight than is act ually on the seat.
... Secure unused safety be lts on the rear seat
c::;, page 166 .
Always remember : Even tho ugh yo ur vehicle is
equipped with an Advanced Airbag system, all
chi ldren, especially those 12 years and young
er, shou ld always r ide in the back seat proper-
ly restrained for their age and size. .,.
