8_ WARNING
To reduce the risk of injury when an airbag
inf lates, a lways wear safety belts prope rly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of injury is much higher.
- You wi ll also receive serio us injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in­
flates - even with an Advanced Airbag

More important things to know about
front airbags
Fig . 167 Inflated front a irbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfo ld prope rly and pro­
vide supplemental protection in a frontal co l­
lision .
The front airbags are designed to provide ad­ d itional protect ion for the chest and face of
the dr iver and the front seat passenger when :
- safety belts are worn properly, -
the seats have been positioned so that the
occupant is properly seated as far as possi­
b le from the airbag,
- and the head restraints have been properly
adjusted .
Bec ause airb ags infla te in the blin k of an eye
with great force, th ings you have on your lap
or have p laced on the seat co uld become dan ­
gerous pro jecti les, and be p ushed into you if
the a irbag inf lates .
When an airbag deploys, fine dust is re leased .
This is no rma l and is not caused by a fire i n
the vehicle . This dust is made up mostly of a
powder used to lubricate the airbags as they
deploy. It could irr itate skin.
It is important to remembe r that wh ile the
supplementa l airbag system is designed to re­
duce the like lihood of serious injur ies, other
injur ies, for example swelling, bruising and
minor abrasions, can also happen when air­
bags inflate . A irbags do not protect the arms
o r the lower parts of the body . Front a irbags
supplement the three-point safety bel ts only
i n some fronta l co llisions in which the vehicle
de celeration is h igh enough to deploy the air­
bags .
Front airbags will not deploy:
-if the ignition is sw itched off when a c rash
o ccu rs,
- in side co llisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measu red by
the airbag system is less than the min imum
threshold needed for a irbag deployment as
reg istered by the electronic contro l unit .
The front pa ssenge r airbag also will not
deploy:
- when the front passenger seat is not occu­
pied,
- when the weight on the front passenger
seat as sensed by the Advanced Airbag Sys­
tem ind icates that the front a irbag on the
passenger side has to be turned off by the ..,.

Monitoring the
Advanced Airbag System
Cl! (USA models)/!f (Canada models)
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 BAG 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 functioning properly
whenever the ignition is on. Each time you
switch on the ignition, the airbag monitoring
indicator light
I (USA mode ls)/ fll (Canada
models) will come on for a few seconds (self
d iagnost ics).
The system must be inspected when the
indicator light
I (USA models)/E,I
(Canada models):
-does not come on when the ignition is
switched on,
- does not go out a few seconds after you have switched on the ignition, or
- comes on while driving.
If an airbag system malfunct ion is dete cted,
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
light will come on and stay
on whenever the ignition is on.
A WARNING
An airbag system that is not functioning
properly cannot provide supplemental pro­
tection in a frontal crash.
- If the airbag indicator light
c::> page 18
comes when the vehicle is be ing used,
have the system inspected immediate ly
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.

The PASSENGER AIR BAG OFF light will come
on and stay on to tell you when the front Ad­
vanced Airbag on the passenger s ide has been
turned
off by the electron ic control unit. Each
t ime you switch on the ign it ion, the
PASSEN­
GER AIR BAG OFF
light will flash for a few
seconds and:
- will stay on if the front passenger seat is not
occupied,
- will stay on if there is a small ch ild or child
restraint on the front passenger seat,
- w ill go out if the front passenger seat is oc ­
cupied by an adult as registered by the
weight-sensing mat.
The
PASSENGER AIR BAG OFF light must
come on and stay on
if the ignition is on and
- a car bed has been installed on the front seat, or
- a rearward-facing child restraint has been
installed on the front passenger seat, or
- a forward-facing child restraint has been in-
stalled on the front passenger seat, or
liJI,

-the weight registered on the front passen­
ger seat is equa l to or less than the com­
bined weight of a typical 1 year -old restrain­
ed in one of the rear-fac ing or forward­
facing infant restraints listed in Federal Mo­
tor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified .
If the front passenger seat is not occupied,
the front airbag will not deploy, and the
PAS­
SENGER AIR BAG OFF
light will stay on . Nev­
er insta ll a rearward-facing child restra int on
the front passenger seat, the safest place for
a child in any kind of child restraint is at one
of the seating positions on the rear seat
¢ page 155, Child restraints on the front seat
- some important things to know
and
¢ page 177, Child Safety.
If the PASSENGER AIR BAG OFF light comes
on
when one of the conditions listed above is
met, be sure to check the light regularly to
make certa in that the
PASSENGER AIR BAG
OFF
light stays on cont inuously whenever the
ignit ion is on. If the
PASSENGER AIR BAG
OFF light does not appear on and does not
stay on all the time, stop as soon as it is safe
to do so and
- react ivate the system by switching the igni­
t ion off and then switch ing 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 correct ly
routed through the child rest raint as descri­
bed in the child restrai nt manufactu rer's i n­
str ucti ons;
- make sure that the conver tible locking fea­
ture on the safety belt for the front passen­
ger seat has been activated 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 belt latch
on the seat can do its job
¢ page 187.
- make sure that things that may increase the
weight of the chi ld and child seat are not be­
ing transported on the front passenger seat;
Airbag system 165
-make sure that the safety belt tension sen ­
sor is not blocked. Shake the safety belt
latch on the front passenger seatback and
forth;
- If a strap or tether is being used to tie the
child seat to the front passenger seat, make
sure that it is not so t ight that it causes the
weight-sensing mat to measure more
weight than is actually on the seat .
If the PASSENGER AIR BAG OFF light still
does not come on
and does not stay on con­
ti nu ously (when the ignition is switched on),
- take the child restraint off the front passen -
ger seat and install it properly at one of the
rear seat positions. Have the airbag system
inspected by your Audi dealer immed iately.
- move the ch ild to a rear seat position and
make sure that the child is properly restra in­
ed in a ch ild restra int that is appropriate for
its size and age .
The
PASSENGER AIR BAG OFF light should
NOT come on when t he ignition is on and an
adult is sitting in a proper seating position on
the front passenger seat. If the PASSENGER
AIR BAG OFF
light comes on and stays on or
flashes fo r about 5 seconds wh ile d riving, un­
der these circumstances , make sure that:
- the adult on the front passenge r seat is
prope rly seated on the center of the seat
cushion with his or her back up against the
backrest and the backrest is not re clin ed
¢ page 136, Proper occupant seating posi­
tions,
- the adult is not taking weight off the seat by

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not functioning
properly cannot provide supplemental pro­
tect ion in a frontal crash.
- If the airbag indicator light
c:> page 18
comes when the vehicle is be ing used,
have t he system inspected immediate ly
by you r authorized Aud i dea le r.
It is pos­
s ible that the a irbag will inflate when it
is not s upposed to, or w ill not inflate
w hen it sho uld.
A WARNING
If the front air bag infla tes, a c hild wi tho ut
a chil d restra int, or in a rearward-fac ing
child safety seat, or in a forward-facing
child rest raint that has not been prope rly
installed will be serious ly injured and can
be killed.
- Even though your ve hicle is equipped
with an Advanced Airbag System, make certain that all children, especially 12
years and younger, a lways ride on the
back seat properly restra ined fo r the ir
age and size .
- Always insta ll forward or rea r-facing
child seats on the rea r seat -even w ith
an Advanced Airbag System.
- If you must install a rearward-fac ing
child seat on the front passenge r seat
because of except io na l circumstances
and the
PASSENGER AIR BAG OFF ligh t
does not appe ar and stay on, imme diate- ly insta
ll the rear-facing child seat in a
rear seat ing pos ition and have the airbag
system inspected by your Audi dealer.
- A t ight tether or other strap on a rear­
ward-facing child restraint attached to
the front passenger seat can put too
much p ressu re on the weight-sensing
mat in the seat and reg iste r mor e we ight
than is actually on the seat. The heavie r
weight regis tered can make the sys tem
wo rk as though an adult we re on the seat
and deploy the Advanced Airbag when it
m ust be suppressed causing serious or
even fata l injury to t he chi ld .
- If, in exceptiona l circumstances, you
m ust install a forward-facing c hild re­
straint on the front passenger seat, al ­
ways move the seat into its rearmost po­ sition in the seat's fore and aft ad just­
ment range, as far away from the a irbag
as poss ible. The backrest mus t be ad just­
ed to an upright pos ition. Make su re that
the
PASSENGER AIR BAG OFF light
comes on and st ays o n all the time when ­
eve r the ignit ion is swit ched on .
A WARNING
- If the PASSENGER AIR BAG OFF light
does not go o ut when an a dult is sitting
on the front passenger seat after taking
the steps described above, make sure the
adu lt is properly seated and restra ined at
one of the rear seat ing pos itions.
- Have the airbag system inspected by
your Aud i dealer before transporting
a nyo ne 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 the
PASSENGER AIR BAG

1 7 0 Airbag system
How knee airbags work
The risk of injury to the leg area can be re­
duced by fully inflated knee airbags.
Fig . 170 Inflated airbags protect ing in a frontal coll i­
sio n
The knee airbag system has been designed so
that the a irbags for the driver and front pas­
senger deploy in certain but not all frontal
collis ions ..
If the front airbags deploy, the knee airbags
also deploy i n frontal collisions when the de­
ployment threshold stored in the control unit
is met .
When the system deploys, the airbags fill
with a propellant gas, and inflate between the
lower part of the instrument panel and the
driver and the lower part of the instrument
panel and the front passenger
9 page 162,
fig. 167.
Although they a re not a soft pillow, they can
"cush ion " the impact and in this way they can
he lp to reduce the risk 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 . T he ai rbags also
inflate with a great deal of force and it is im ­
po rtan t for occupant sa fety that not hing
should be in their way when they deploy.
Fu lly inflated airbags in combination with
properly worn safety bel ts slow down and lim­
it the oc cupant's forwa rd movement and help
to reduce the risk of injury. 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.
The re is a lot that you and your passengers
must know and do to he lp the sa fety belts and
airbags to prov ide supplemen ta l protect ion.
A WARNING ~
An inflat ing knee a irbag can cause serio us
i njury . Wearing safety belts incorrectly and
improper seating positions increase the
risk of ser ious persona l injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you a re seated too close
to any of the airbag locations. 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
d istances:
- 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 a irbag de­
p loy .
- Always make s ure that the knee airbag
can inf late without inte rfe rence. Objects
between yo u and the airbag can increase
the risk of injury in an accident by inter ­
fering w ith the way the airbag deploys or
by being pushed into you as the airbag
deploys.
- Never let anybody, espec ia lly children
o r anima ls ride in the footwell in front

of the passenger seat. If the airbag de­
ploys, this can result in serious or fatal
injuries.
- Never carry objects of any kind in the
footwell area in front of the driver's or passenger's seat. Bulky objects (shop­
ping bags, for example) can interfere
with 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

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
---
Fig. 171 Side airbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests
¢fig. 171 and the rear
backrest facing the doors. They are identified
bytheword "AIRBAG".
The 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
- two rear side airbags
Airbag system 1 71
- the airbag warning light in the instrument
cluster.
The airbag system is monitored electronically
to make certain that it is functioning properly
at all times. Each time you switch on the igni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics).
The side airbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the driver's, front and rear passenger's
upper torso on the side of the vehicle that is
struck in a side collision. The airbag deploys
only in side impacts and only when the vehicle
acceleration registered by the control unit is
high enough.
If this rate is below the refer­
ence value programmed into the control unit,
the side airbags will not be triggered, even
though the car may be badly damaged as a re­
sult of the collision.
It is not possible to de­
fine an airbag triggering range that will cover every possible angle of impact, since the cir­
cumstances will vary considerably between
one collision and another. Important factors include, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc. ¢
page 173, Important
safety instructions on the side airbag system.
Aside from their normal safety function, safe­
ty belts work to help keep the driver or front
passenger in position in the event of a side
collision so that the side airbags can provide
protection.
The airbag system is
not a substitute for your
safety belt . Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the side airbag system
can only help to protect you if you are wearing
your safety belt and wearing it properly. This
is another reason why you should always wear
your safety belts, not just because the law re­
quires you to do so¢
page 145, General
notes.
It is important to remember that while the
supplemental side airbag system is designed
to reduce the likelihood of serious injuries,
other injuries, for example, swelling, bruising,
IIJ>,

Important safety instructions on the
side 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 act accordingly to help the
safety belts and airbags do their job to pro­
vide supplemental protection .
A 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.
- Never install seat covers or replace ­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
deploy.
- Damage to the original seat covers or
to the seam in the area of the side air­ bag module must always be repaired
immediately by an authorized Audi
dealer.
Airbag system 173
- 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 use the built -in coat hooks only
for lightweight clothing . Never leave any
heavy or sharp-edged objects in the
pockets that may interfere with side air­
bag deployment and can cause personal
injury in an accident.
- 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 ~
page 177, 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 .,.. •

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 146, 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
adu lts.
Because children's bod ies 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 children .
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,
on ly an appropriate chi ld 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 chi ld's size ~
page 180, Impor­
tant safety instructions for using child safety
seats.
Please be sure to read and heed all of
the important information and WARNINGS
about ch ild 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-
Child Sa fet y 177
straints are on the front passenger seat . Be­
cause of the large amount of important infor­
mation, we cannot repeat it a ll 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 chi ldren .
.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 ikin g the interior or by be­
ing ejected from the vehicle during a
sudden maneuver or impact. An un re ­
strained or improper ly 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 a irbag in­
flates. A child in a rearward-fac ing ch ild
safety seat installed on the front passen­
ger seat will 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 backrest, center
armrest, or door.

178 Child Safety
-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 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 th e
driver side. The low ris k deployment criteria
are intended to reduce the risk of injury
through interact ion with the airbag t hat 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 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 we ight 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 chi ld restraint is being
used on the front passenge r seat with a typi­
cal 1 year -old ch ild, the A dvanced Airbag Sys­
tem compares the we ight measured by the
weight sensing mat with the information stor­
ed in the electronic control unit.
The electron ic contro l unit al so registers the
tension on the front passenger safety be lt.
The tension on the safety be lt for the front
passenger seat will be different for an adult
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.
T he sensor below the latch for the safety belt
for the front seat passenger measures the
tension on the belt . T he input from this sen­
sor is t hen used w ith the we ight to "decide",
whether there is a ch ild restraint with 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
Regard less of the child restraint that you use,
make sure that it has been certified 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 chi ld restraint is p roperly instal led at
one of the rear seat ing pos itions . If in excep­
tional ci rcumstances you must use it on the
front passenger seat, carefu lly read all of the
information on child safety and Advanced Air­
bags and heed a ll of the app licable WARN­
INGS. Make certain that the child restraint is
correctly recognized by the weight-sensing
Child Sa fet y 1 79
mat inside the front passenger seat, that the
front passenger airbag is turned off and that
the a irbag status is always correct ly signaled
by the
PAS SENGE R AIR BAG OFF light.
Many types and models of child restraints
have been available over t he years, new mod­
els are introduced regu larly incorporating new
and improved des igns and o lder models are
taken out of product ion. Ch ild restraints are
not standard ized . Child restraints of the same
type typ ically have d ifferent weights and sizes
and different 'footpr ints,' the size and shape
of the bottom of the ch ild restrai nt that sits
o n the seat, when they a re insta lled on a veh i­
cle seat. These diffe rences make it v irtually
impossible to certify compliance with the re­
quirements for advanced airbags with each
and every ch ild restraint that has ever been
sold in the past or will be sold over the course
of the useful life of your veh icle.
For this reason, the United States National
Highway Traffic Safety Adm inistrat ion has
published a list of spec ific 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
Standa rd 208. These chi ld restraints are :
