make certain that the PASSENGER AIR BAG
OFF
light stays on continuous ly whenever the
ignition is on. If the
PASSENGER AIR BAG
OFF
light does not appear and not stay on all
the time, stop as soon as it is safe to do so
and
- reactivate the system by turning the ignition
off and then turning it on again;
- remove and reinstall the child restraint.
Make sure that the child restraint is properly
installed and that the safety belt for the
front passenger seat has been correctly
routed around the child restraint as descri­
bed in the child restraint manufacturer's in­
structions;
- make sure that the convertible locking re­
tractor on the safety belt for the front pas­
senger seat has been act ivated and that the
safety belt has been pulled tight. The belt
must not be loose or have loops of slack so
that the sensor below the safety be lt latch
on the seat can do its job
c::> page 175 .
-make su re that things that may increase the
weight of the child and child safety seat are
not being transported on the front passen­
ger seat;
- make sure that the safety belt tension sen­
sor is not blocked. Shake the safety belt
latch on the front passenger seat back and
forth;
- If a strap or tether is being used to tie the child safety seat to the front passenger
seat, make sure that it is not so tight that it
causes the we ight-sensing mat to measure
more weight than is actua lly on the seat.
If the PASSENGER AIR BAG OFF light still
does not come on
and does not stay on con­
tinuously (when the ignition is switched on),
- take the chi ld restraint off the front passen-
ger seat and install it properly at one of the
rear seat positions . Have the a irbag system
inspected by your authorized Audi dealer
immediately .
- move the ch ild to a rear seat pos it io n and
make sure that the child is properly restrain­
ed in a child restraint that is appropriate for
it s size and age. The
PASSENGER AIR BAG OFF light
should
NOT come on when the ignition is on and an
adult is s itting in a proper seating position on
the front passenger seat. If the
PASSENGER
AIR BAG OFF
light comes on and stays on or
flashes for about 5 seconds wh ile driving, un­
der these cir cumstances, make sure that:
- the adult on the front passenger seat is properly seated on the center of the seat
cushion with his or her back up aga inst the
backrest and the backrest is not recl ined
c::> page 12 7, Proper occupant seating posi­
tions,
- the adult is not taking weight off the seat by
holding on to the passenger assist handle
above the front passenger door or support­
ing their weight on the armrest,
- t he safety belt is being properly worn and
t hat there is not a lot of s lack in the safety
be lt webb ing,
- accesso ry seat covers or cushions or other
t hings that may cause an incorrect reading
or impression on the weight-sensing mat
under the upho lstery of the seat have been
removed from the front passenger seat,
- a safety belt extender has not been left in
the safety belt latch for the front passenger
seat.
In addition to the
PASSENGER AIR BAG OFF
light in the center of the instrument panel,

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An a irbag system that is not functioning
properly cannot provide supplemental pro­
tection in a frontal c rash.
- If the airbag ind icator light
c::> page 20
comes when the veh icle is being used,
have the system inspected immediately
by your authorized Audi dealer .
It is
-

'"" N
0 ::.,: co ,...., \!) 1.1'1 ,...., 1.1'1 ,....,
possible 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 ch ild without
a child restra int, in a rearward-facing child
safety seat or in a forward-facing child re­
st raint that has not been properly insta lled
w ill be seriously injured and can be k illed.
- Even though your veh icle is equipped
with an Advanced Airbag System, make certain that a ll children, especially 12
ye ars and younge r, a lways ride on the
back seat properly restrained fo r their
age and size.
- Always instal l forw ard or rea r-facing
child safety seats on the rear seat -even
with an Advanced Airbag System.
- If you mus t install a rearward -facing
child safety seat on the front passenger
seat because of exceptional circ umstan­
ces and the
PASSENGER AIR BAG OFF
light does not appear and stay on, imme ­
diately install the rear-fac ing ch ild safety
seat in a rear seating position and have
the a irbag system inspected by you r au­
tho riz ed Aud i dea le r.
- A tight tether or other strap on a rear­
wa rd-fac ing child restra int attached to
t h e fro nt passenger sea t can put too
much pressure on the weight-sens ing
mat in the seat and register mo re weight
than is ac tually on the seat. The heavier
weight registe red can make the system
wor k as though an adu lt were on the seat
and dep loy the Advanced Airbag when it
must be suppressed caus ing serious or
even fatal injury to the child .
- If, in exceptional circumstances, you
must install a forward -facing child re ­
st rain t on the front passenger seat, a l­
ways move the seat into its rearmost po­
sit ion in the seat's fo re and aft adjust­
ment r ange, as far away from the airb ag
as possib le. The backrest m ust be adjus t­
ed to an upr ight position. Make sure that
A irbag system 157
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 tak ing
the steps described above, make su re the
adu lt is prope rly seated and restra ined at
one o f the rea r seat ing pos itions.
- Have the airbag system inspected by
your author ized Audi dealer befo re trans­
port ing anyone on the front pas senger
seat.
@ Tips
If t he weig ht-sensing mat in the front pas ­
senger seat detects an empty sea t, the
front airbag on the p assenger side will be
turned off, and
PASSENGER AIR BAG OFF
will stay on .
Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different p laces on your Aud i. Insta lling,
removing, servicing or repa iring a part in an
area of the vehicle can damage a part of an
a irbag system and p revent that system from
working p rope rly in a coll is ion.
There are some important t hings you have to
k n ow to make sure that the effectiveness of
t h e system w ill not be impaired and that d is­
ca rded components do not cause inju ry o r pol­
l ute the environment.
A WARNING
Im proper care, serv icing and rep air proce­
d ur es can increase the risk of personal in ­
ju ry and death by preventing an a irbag
from deploying when needed or deploying
an a irbag unexpectedly:
- Never cover, obst ruct, or change the
steer ing whee l horn pad or airbag cover
or the instrument panel or mod ify them
in any way. •
•

160 Airbag system
can only help to protect you if you a re wearing
your safety belt and wearing it properly. This
i s another reason why you should always wear
your safety belts, not just because the law re­
quires you to do so
r:::> page 136, General
notes .
It is important to remember that whi le the
supp lemental side a irbag system is designed
to reduce the likelihood of serious injuries,
other injuries, for example, swell ing, bruising,
and minor abras ions can also be associated
with deployed side a irbags . Remember too,
side ai rbags wi ll deploy on ly once and on ly in
cer tain k inds of accident s -yo ur safety belts
are a lways there to offer protect io n.
Vehicle damage, repa ir costs or even the lack
of veh icle damage are not necessar ily an indi­
cation of over-sensi tive or failed airbag activa­
tion . In some co llisions, both fron t and side
airbags may inflate. Remember too, that air­
bags will dep loy only once and only in certain
kinds of collisions -your safety belts are al­
ways there to offer protection in those acci­
dents in which airbags are not supposed to
deploy or when they have already deployed .
The side airb ag syst em will not depl oy :
- when the ignition is turned off
- in side collisions when the acce leration
measured by the sensor is too low
- in front-end col lisions
- i n rear-end co llisions
- i n ro llovers .
In some types of accidents the front airbags,
side curtain airbags and side airbags may be
tr iggered together .
A WARNING
-Saf ety belts and the a irbag system w ill
only p rov ide protection when oc cupan ts
are in the p roper seating posit ion
c:!;>page 161.
-If the airbag indicator light c:!;> page 20
comes whe n the vehicle is be ing used,
have the system inspected immediate ly
by your authorized Audi dea ler . 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.
F ig. 158 In flated sid e airbags on left s ide of vehicle
When the system is trigge red, the a irbag is
filled wi th propellant gas and b reaks through
a seam in the seat su rface area marked "AIR ­
BAG".
It expands between the side trim panel
and the passenger. In order to help provide
t hi s addit ional protection, the side airbag
must inflate within a fraction of a second at
very h igh speed and with great force. The sup­
pleme ntal side airbag could injure you if your
seat ing position is not proper or upright or if
items are located in the area where the sup­
plementa l side airbag expands . This applies
especially to ch ildren
c:!;> page 165, Child Safe­
ty.
Supplemen tal side ai rbags inflate be tween
the oc cupant and the door panel on the side
of the vehicle that is struck in certain side col ­
li sion ¢
fig. 158.
Although they are not a soft p illow, 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 d ust may deve lop when the a irbag de­
ploys . This is normal and does not mean there
is a fire in the vehicle.

166 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 .,.

A WARNING
If exceptional circumstances require the
use of a forward-facing child restraint on
the front passenger's seat, the child's safe­
ty and well-being require that the follow­
ing special precautions be taken:
- Make sure the forward-facing seat has been designed and certified by its manu­
facturer 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 infant carrier.
- Always move the front passenger seat in­
to the rearmost position of the passen­
ger seat's fore and aft adjustment range,
and as far away from the airbag as possi­
ble before installing the child restraint.
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its
fore and aft adjustment range.
- Always make sure the backrest is in an
upright position.
- Make sure that the

The vehicle's safety belts alone will not fit
most children until they are at least 4
ft. 9 in .
(57 inches/1.45 meters) tall and weigh about
80 lbs. (36 kg). Booster seats raise these chil­
dren up so that the safety belt will pass prop­
erly over the stronger parts of their bodies
and the safety belt can help protect them in a
crash.
.,. Do not use the convertible locking retractor
when using the vehicle's safety belt to re­
strain a child on a booster seat.
... The shoulder belt must lie as close to the
center of the child's collar bone as possible
and must lie flat and snug on the upper
body. It must never lie across the throat or
neck . The lap belt must lie across the pelvis
and never across the stomach or abdomen .
Make sure the belt lies flat and snug. Pull on
the belt to tighten if necessary.
.,. If you must transport an older child in a
booster seat on the front passenger seat,
you can use the safety belt height adjust­
ment to help adjust the shoulder portion
properly.

Installing a child safety
seat
Securing a child safety seat using a
safety belt
Safety belts for the rear seats and the front
passenger's seat can be locked with the con­ vertible locking retractor to properly secure
child safety seats.
The safety belts emergency locking retractors
for the rear seats safety belts and for the
Child Safety 175
front passenger's seat safety belt have a con­
vertible locking retractor for child restraints.
The safety belt must be locked so that belt
webbing cannot unreel. The retractor can be
activated to lock the safety belt and prevent
the safety belt webbing from loosening up
during normal driving. A child safety seat can
only be properly installed when the safety belt
is locked so that the child and child safety
seat will stay in place .
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and young­
er, should always ride in the back seat proper­
ly restrained for their age and weight.
A WARNING
=
Improperly installed child safety seats in-
crease the risk of serious personal injury
and death in a collision.
- Always make sure that the safety belt re­
tractor is locked when installing a child
safety seat. An unlocked safety belt re­
tractor cannot hold the child safety seat in place during normal driving or in a
crash .
- Always buckle the child safety seat firmly
in place even if a child is not sitting in it.
A loose child safety seat can fly around
during a sudden stop or in a collision.
- Always make sure that the rear seat
backrest to which the center rear safety
belt is attached is securely latched when­
ever the rear center safety belt is being
used to secure a child restraint.
-If the backrest is not securely latched,
the child and the child restraint will be
thrown forward together with the back­
rest and will strike parts of the vehicle
interior. The child can be seriously in­
jured or killed.
- Never install rearward-facing child safety
seats or infant carriers on the front pas­
senger seat. A child will be seriously in­
jured and can be killed when the passen- ger airbag inflates. .,_ •
