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
PASSEN
GER AIR BA G OFF
light.
The Advanced Airbag System (including the
electronic control unit, sensor circuits and sys
tem wiring) is monitored continuously to
make sure that it is functioni ng properly
whenever the ignit ion is on. Each t ime you
turn on the ignition, the airbag monitoring in
d icator light
fl will come on fo r a few seconds
(self diagnosti cs) .
The system must be inspected when the
indicator light
fl:
- does not come on when the ignit ion is
swit ched on,
- does not go out a few seconds after yo u
have swi tched on the ign ition, o r
- comes on w hile d riving .
If an airbag system malfunction is detected,
the indicator light will first start flash ing to
catch the driver's atte ntion and then stay on
continuously to se rve 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

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not functioning properly cannot provide supplemental pro
tection in a frontal crash.
- If the airbag indicator light¢
page 15
comes when the vehicle is being used,
have the system inspected immediately
by your authori zed Audi dealer. It is pos
sible that the airbag will inflate when it
is not supposed to, or will not inflate
when it should .
A WARNING
If the front airbag inflates, a child without
a child restraint, in a rearward-facing child
safety seat or in a forward-facing child re
straint that has not been properly installed
will be seriously injured and can be killed.
- Even though your vehicle is equipped
with an Advanced Airbag System, make certain that all children, especially 12
years and younger, always ride on the back seat properly restrained for their
age and size.
- Always install forward or rear-facing
child safety seats on the rear seat -even
with an Advanced Airbag System.
- If you must install a rearward-facing
child safety seat on the front passenger
seat because of exceptional circumstan
ces and the
PASSENGER AIR BAG OFF
light does not appear and stay on, imme
diately install the rear-facing child safety
seat in a rear seating position and have
the airbag system inspected by your au
thorized Audi dealer.
- A tight tether or other strap on a rear
ward-facing child restraint attached to
the front passenger seat can put too
much pressure on the weight-sensing
-
mat in the seat and register more weight
than is actually on the seat. The heavier
weight registered can make the system
work as though an adult were on the seat and deploy the Advanced Airbag when it
must be suppressed causing serious or
even fatal injury to the child.
- If, in exceptional circumstances, you
must install a forward-facing child re
straint on the front passenger seat, al
ways move the seat into its rearmost po
sition in the seat's fore and aft adjust
ment range, as far away from the airbag
as possible. The backrest must be adjust
ed to an upright position. Make sure that
the
PASSENGER AIR BAG OFF light
comes on and stays on all the time when
ever the ignition is switched on .
A WARNING
-
-
-If the PASSENGER AIR BAG OFF light
does not go out when an adult is sitting
on the front passenger seat after taking
the steps described above, make sure the
adult is properly seated and restrained at
one of the rear seating positions.
- Have the airbag system inspected by
your authorized Audi dealer before trans
porting anyone on the front passenger
seat.
(D Tips
If the weight-sensing mat in the front pas
senger seat detects an empty seat, the
front airbag on the passenger side will be
turned off, and
PASSENGER AIR BAG OFF
will stay on.
Repair , care and disposal of the airbags
Par ts of the airbag system are ins talled at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision. .,..

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 71 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
Q page 178, Child Safe
ty.
Supplementa l side airbags inflate between
the occupant and the door pane l on the side
of the vehicle that is struck in certain side col
lision
Q fig . 171.
A lthough they are not a soft pillow, they can
"cushion" the impact and in th is way they can
he lp to reduce the risk of injury to the upper
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 passengers
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.
-A lways 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 hei r 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

~ fig . 173.
When the system is tr iggered , the side c urtain
airbag is filled with propellant gas and breaks
through a seam above the front and rear side
windows identified by the AIRBAG label. In or
der to help provide this additional protection,
the side curtain airbag must inflate within the
blink of an eye at very high speed and w ith
great force. The side curtain airbag cou ld in
jure you if your seat ing pos ition is not proper
or upright o r if items are located in the area
where the suppleme nta l side cu rtain airbag

Important safety instructions on the
side curtain airbag system
Airbags are only supplemental restraints . Al
ways properly wear safety belts and ride in a
proper seating position.
There is a lot that you and your passengers
must know and do to help the safety be lts and
airbags do the ir job to provide supplementa l
protection.
A WARNING
Improperly wear ing safety belts and im
proper seating positions increase the risk
of serious personal injury and death when
ever a veh icle is being used .
- Never let occupants p lace any parts of
their bodies in the a rea from wh ich the
side cu rtain airbags inflate.
- Always make sure that the side curta in
airbags can inflate w ithout interference.
Uns uitable accessories fitted inside the
A irbag system 177
expansion range of a head airbag can
dangerously interfere with its funct ion. A
deploying head airbag develops enough
force to catapult any p iece of add-on
component out of its path of inflation
and into the passenger compa rtment. An
o cc u pant hit by such a projectile can suf
fer serious injury or death~

Technical Modifications.
- Do not swive l the sun visors to the side i f
you have any ob jects clipped onto them
(for examp le pens) . If the airbag should
deploy, you could be injured by these ob
jects .
- Use the bui lt - in coat hooks only for ligh t
weight clothing . Never leave any heavy or
sharp-edged objects in the pockets that
may interfere with airbag dep loyment
and can cause personal injury in an acci
dent.
- Never use hangers to hang clothing from
the hooks.
- On ly use factory-installed sun shades or,
in the case of shades installed after the
veh icle leaves the factory, only Audi roll
up sunscreens may be used~

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
~ page 150, What happens to occupants not
wearing safety belts?.
But unlike adults and
teenagers, their muscles and bones are not
fu lly 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 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 ch ildren.
In a fronta l crash at a speed of 20 -35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infant w ill be more than 20 t imes 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 ser ious 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 ch ild's size ~
page 181, 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 A irbags, 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 th is
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
-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 iking the i nterior or by be
ing ejected from the vehicle during a
sudden maneuver or impact. An unre
strained or improperly restrained chi ld is
also at greater risk of injury or death
through contact with an inflating airbag.
- A suitable chi ld 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 ser iously 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, center
armrest, or door.
II>-

-Always install rear-facing child safety
seats on the rear seat.
- 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 rear-facing child safety seat in
a rear seating position and have the air
bag system inspected immediately by
your 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
Child Safety 1 79
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 ..,.
•
•

180 Child Saf ety
seat. The weight of a child restraint and its
"footprint" vary for different kinds of chi ld re
straints and for the d ifferent models of the
same kind of child restraint offered by child
restra int manufacturers.
The weight ranges for the individual types,
makes and mode ls of ch ild restra ints 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 A ir
bag System. When a ch ild restrai nt is being
used on the front passenger seat with a typi
cal 1 yea r-old ch ild, the Advanced Airbag Sys
tem compares the we ight measured by the
weight sensing mat with the in formation stor
ed in the electronic control unit.
The ele ctron ic cont rol unit also registers the
tension on the front passenge r safety belt.
The tension on the safety be lt fo r the front
passenger seat will be different for an ad ult
who is properly using the safety belt as com
pared to the tension on the belt when it is
used to attach a child restraint to the seat.
The sensor below the latch for the safety belt
for the front seat passenger measu res the
tension on the be lt. The input from this sen
sor is then used with the we ight to "decide",
whe ther there is a ch ild restraint w ith a typ ica l
1 year-o ld child on the front passenger seat
and whether or not the airbag must be turned
off .
Child restraints and Advanced Airbags
Regardless of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards a nd has been certified by its manu
facture r fo r u se w ith an airbag. Always be s ure
that t he ch ild res traint is p rope rly insta lled at
one o f th e rear seat ing pos itions. If in excep
tional c ircu mstances you must use it on the
front passenger seat, caref ully read all of the
info rmation on c hild safety and Advanced Air
bags and heed all of the applicable WARN
INGS. Make certain that the child restraint is
correctly recognized by the weig ht-sensing mat
inside the front passenger seat, that the
front passenger airbag is turned off and that
the a irbag stat us is always cor rect ly signa led
by the
PASSENGER AIR BAG OFF light.
Many types and models of child res traints
have been available over the years, new mod
els are introduced regu larly incorporating new
and improved des igns and older models are
taken out of product ion. Ch ild restraints are
not standard ized . Child restraints of the same
type typically have d ifferent weights and sizes
and diff erent 'footpr ints,' the s ize and shape
of the bo ttom of the ch ild restra int that sits
o n t he seat, when they a re inst alled on a vehi
cle sea t. Th ese d ifferences make it vir tually
impossible to certify compliance with the re
quirements for advanced airbags with eac h
and every child restra int that has ever been
sold in the past or will be sold over the course
of the useful life of your veh icle.
For th is reason, the United States National
Highway Traffic Safety Adm inistrat ion 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 i n your veh icle w ith the suppression
requirements of Federal Motor Vehicle Safety
Standa rd 208. These chi ld restraints are:
