Airbag system Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job , occupants must al­
ways properly wear their safety belts and be
in a proper seating position.
For your safety and the safety of your passen­
gers, before driving off, always:
"" Adjust the dr iver's seat and steering wheel
properly ¢
page 161,
"" Adjust the front passenger's seat properly
¢page 72 ,
"" Wear safety be lts properly ¢
page 173,
"" Always properly use the proper child re-
straint to protect chi ldren ¢
page 200.
In a collision, airbags must inflate within the blink of an eye and with considerable force .
The supplemental airbags can cause injuries if
the driver or the front seat passenger is not
seated properly . T herefore in order to help the
a irbag to do its job, it is important, both as a
driver and as a passenge r to s it properly at all
times.
By keeping room between your body and the
steer ing wheel and the front of the passenger
compartment, the airbag can inflate fully and
comp letely and provide supplemental protec­
tion in certain frontal collisions ¢

There is a lot that the driver and the passen­
gers can and must do to help the individual
safety features installed in your Aud i work to­
gether as a system.
Proper seat ing pos ition is important so that
the front airbag on the driver s ide can do its
job. If yo u have a physical impa irment or con-
A irbag system 179
dition that prevents yo u from sitting properly
on the driver seat with the safety belt properly
fastened and reach ing the peda ls, or if you
have concerns with regard to the function or
operation of the Advanced Airbag System,
please contact your author ized Audi dealer or
qualified workshop, or call Audi Customer Re­
l ations at 1-800-822-2834 for poss ible modi­
ficat io ns to your veh icle.
When the airbag system dep loys, a gas gener ­
ator will fill the a irbags, break open the pad­
ded covers, and inflate between the steer ing
whee l and the dr iver and between the instru­
ment pane l and the front passenger. The a ir­
bags will deflate immediately after dep loy­
ment so that the front occupants can see
through the windshield again without inter­
ruption .
All of th is takes place in the blink of an eye, so
fast that many people don't even realize that
the airbags have deployed. The airbags a lso
inflate with a great dea l of force and nothing
should be in their way when they deploy.
Front airbags in combination with properly
worn safety belts slow down and lim it the oc ­
cupant's forward movement . T ogether they
help to prevent the driver and front seat pas­
senger from h itti ng pa rts of the inside of the
vehicle while reducing the forces acting on the
occupant during the crash . In this way they
help to reduce the risk of injury to the head
and upper body in the crash. Airbags do not
protect the arms or the lower parts of the
body.
Both front airbags will not inflate in all fronta l
collisions . The triggering of the airbag system
depends on the vehicle de ce leration rate
caused by the collision and regis te red by the
electron ic control unit. If th is rate is below
the reference value programmed into the con ­
trol unit, the airbags will not be trigge red ,
even though the car may be bad ly damaged as
a res ult of the co llision . Ve hicl e damage, re­
pair costs or even the lack of veh icle damage
is not necessarily an indication of whether an
airbag should inflate or not . .,. •

180 Airbag sys tem
Since the cir cumstances will vary considerab ly
between one collision and anot her, it is not
possib le to def ine a range of vehicle speeds
that will cover every possible k ind and angle
of impact t hat will always trigger the a irbags.
Important factors include, for example, the
nature (hard or soft) of the object which the
car h its, the ang le of impact, vehicle speed,
etc. The front airbags will also not inflate in
side or rea r collisions, or in ro ll-overs .
Always remember : Airbags will deploy only
once, and only in certa in k inds of co llisions.
Your safety belts are always there to offer pro­
tection in those s ituations in which airbags
a re not supposed to deploy, or when they have
a lready deployed; for example, when your ve­
hicle strikes or is struck by another vehicle af­
ter the first co llision.
This is jus t one of the reasons why an a irbag is
a supplementary restra int and is not a substi­
tute fo r a safety belt . The airbag system
works most effect ively when used with the
safety belts. Therefore, always properly wear
your safety belts¢
page 170.
A WARNING
Sitting too close to the steer ing whee l or
instrument panel will dec rease the effec­
t iveness of the airbags and will increase
the risk of personal injury in a collision .
- Never sit closer than 10 inches (2S cm)
to the stee ring wheel or instrument pan­
el.
- If you cannot sit more than 10 inches
( 2 5 cm) from the s teer ing whee l, investi­
gate whethe r adap tive equipmen t may
be available to help you reach the pedals
and increase your seating distance from
the steering wheel.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way, your risk of in jury is much higher.
- You will also receive serio us injuries and
cou ld even be killed if you are up against
the airbag or too close to it when it in­
flates - even with an Advanced Airbag. -
To reduce the risk of injury when an a ir­
bag inflates, always wear safety be lts
properly ¢
page 174, Safety belts.
-Always make certain that ch ildren age 12
or younger always ride in the rear seat. If
children are not properly restrained, they
may be severe ly injured or killed when an
ai rbag inflates.
- Never let children ride unrestrained or
improperly restrained in the vehicle. Ad­
just the front seats prope rly .
- Never ride with the back rest reclined.
- Always sit as far as possible from the
steer ing whee l or the instrument pane l
¢page 161.
-Always sit upright with your back against
the backrest of your seat .
- Never p lace your feet on the instrument
panel or on the seat. Always keep both
feet on the floor in front of the seat to
help prevent serio us in ju ries to the legs
and h ips if the airbag inflates.
- Never recline the front passenger 's seat
to transport objects , Items can a lso
move into the a rea of the s ide airbag or
the front a irbag du ring bra king or in a
sudden maneuve r. Objects nea r the air ­
bags can become projectiles and cause
in jur y when an airbag inflates.
A WARNING ~
Airbags that have deployed in a crash must
be replaced.
- Use on ly orig ina l equipment airbags ap­
proved by Aud i and installed by a trained
technician who has the necessary too ls
and d iagnost ic equipment to properly re­
p lace any airbag in your vehicle and as­
sure system effectiveness in a crash .
- Never permit salvaged or recycled air­
bags to be installed in your vehicle.

Child restraints on the front seat - some
important things to know
.. Be sure to read the important information
and heed the WARNINGS for important de­
tails about chi ldren and Advanced Airbags
i=> page 200.
Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
a ll chi ldren, especially those 12 years and
younger, always ride in the back seat properly restrained for their age and size. The airbag
on the passenger side makes the front seat a potentially dangerous place for a child to r ide .
The front seat is not the safest place fo r a
chi ld in a fo rward-facing chi ld safety seat. It
can be a very dangerous place for an infan t or
a child in a rea rward-facing seat.
The Advanced Airbag System i n your veh icle
has been cert ified to comp ly with the require­
men ts of United States Federa l Mo to r Veh icle
Safety Standard 208 as applicable at the time
your vehicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be t urned off ("sup­
p ressed") if a chi ld up to about one year of
age restrained in one of the rear -facing or for­
ward -facing infant restraints listed i n Federal
Motor Vehicle Safety Standard 208 with wh ich
the Advanced Airbag System in your vehicle
was certified has been installed o n the front
passenger seat . For a listing of the child re­
straints that were used to certify compliance
with the US Safety Sta ndard

The PASS ENG ER AIR BAG OFF light in the in­
strument panel te lls you when the front Ad­
vanced A irbag on the passenger side has been
turned off by the e lectronic control u nit.
Each t ime you turn on the ignition, the
PAS­
SENGER AIR BAG OFF
light w ill come on for a
few seconds and:
- will stay on if the front passenger seat is not
occupied
- will stay on if there is a small child or child
restraint on the front passenger seat
A irbag sys tem 181
- w ill go off if the front passenger seat is oc ­
cupied by an adult as registered by the
weight -sensing mat
c> page 190, Monitor­
ing the Advanced Airbag System.
T he PASSENGER AIR BAG OFF light comes on
whe n the contro l unit detects a tota l weight
on the front passenger seat that req uires the
front a irbag to be turned off.
If the total weight on the front passenger
seat is more than that of a typical 1 year-o ld
c h ild but less than the weight of a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
li ght does not come on). If the PASSENG ER
AIR BAG OFF
light does not come on, the
front a irbag on t he passenger side has not
been t urned off by the elect ronic con trol unit
and can deploy if the control unit senses an
impact that meets the cond itions stored in its
memory .
For exampl e, th e airb ag may deplo y if:
- a small ch ild that is heav ie r than a typical 1
year-old ch ild is o n the front passenger seat
(regard less of whether the child is in one of
the child safety seats listed
c> page 202), or
- a child who has outgrown child restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instr ument cluster and stays on .
The front airbag on the passenger side may
not deploy (the PASSENGER AIR B AG OFF
light does not illum inate and stay lit) even if a
small ad ult or teenager, or a passenger who is
not sitti ng uprig ht w ith their back against a
non -recli ned back rest w it h thei r feet on the
vehicle floor in front of the sea t is on t he front
passenger seat
c> page 161, Proper seating
position for the driver.
If the fron t passenger ai rbag dep loy s, the
Federa l Standard req uires the airbag to meet
the "low risk" dep loyment criteria to reduce
the risk of injury t hro ugh interact ion w ith the
airbag. "Low risk" dep loyment occ urs in those
crashes that take place at lower dece lerat ions ..,. •

A lways remember, a ch ild safety seat or infant
carrier insta lled on the front sea t may be
struck and knocked o ut o f position by the rap ­
id ly inflating passeng er's airbag in a frontal
coll is ion . T he airbag cou ld greatly reduce the
effec tiveness of the child restraint and even
serious ly injure the child during inflat ion.
F or this reason, and because the back seat is
the safest p lace for children - when properly
restra ined acco rd ing to their age and si ze - we
s trongly recommend that children always sit
in the back seat
Q page 200, Child Safety .
A WARNING
A child in a rearward-facing child safety
s e at insta lled on the front passenger seat
w ill be seriously injured and can be k illed if
t he fr ont a irbag inflates - even with an Ad­
vanced Airbag System.
- T he i nflating a irbag will hit the child
safety seat or infant carrier wit h great
f orce and w ill smash the ch ild safety sea t
and child against the backrest , center
armrest, door or roof.
- Always insta ll rear -facing child sa fety
seats on the rear seat.
- If you mus t install a rearward facing
child safety seat on the front passenger
seat because of exceptional circ umstan­
ces and the
PASSENG ER AIR BAG OFF
light does not come on and stay on , im­
med iately install the rea r-facing child
safety seat in a rear seating position and
hav e the a irbag system inspected by you r
authori zed Aud i dealer.
- Forward-fac ing ch ild safety seats instal­
led on the front passenger's seat may i n­
terfere wi th the deployment of the air­
b ag and cau se serious person al injury to
the ch ild .
A WARNING
If, in exceptional c ircumstances, you must
install a forward-facing child restra int 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 s ide a irbag .
- Never put the forward-facing child re­
straint up against or very near the instru­ ment panel.
- Always move the passenger seat into its
rearmost pos ition in the seat's fore a nd
aft ad justment range, as fa r away from
the airbag as possible b efore installing
the forwa rd-fa cing ch ild restra int. The
b ackrest mus t be a djusted to a n up right
position.
- Make s ure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays o n all the
t ime wheneve r the ignition is switched
on.
A WARNING -ra----
To reduce the risk of serious injury, make
sure that the
PASSENGER AIR BAG OFF
light will be displayed whenever a child re­
straint is installed on the front passenger
seat and the ignition is sw itched on.
- If the
PASSENGER AIR BAG OFF light
does not stay on, perform the checks de­
scribed
Q page 190, Monitoring the Ad­
vanced Airbag System .
-Take t he chi ld restraint off the front pas­
senger seat and install it prope rly at one
of the rear seat positions if t he
PASSEN ­
GER AIR BAG OFF
li ght does not stay on.
- Have the airbag system inspected by
your author ized Audi deal er immed iate­
ly .
- Always carefu lly follow instr uctions from
chi ld restraint manufacture rs when in­
st all ing c hild restra ints .
A WARNING
If, in exce ptiona l circumstances, you m ust
i nsta ll a forward or rearw ard-fa cing child
r estra int on the front passenger's seat :
- Imp roper ins tallation o f child restra ints
can reduce their effec tiveness or even

Page 185 of 342

prevent them from providing any
protection.
- An improperly insta lled child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child -even with an Advanced Airbag
System .
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sensing mat and can
cause i njury in a c rash .

There is a lot you need to know about the ai r­
bags in your vehicle . We urge you to read t he
detailed information about airbags, safety
belts and child safety i n this and the other
chapters that make up the owner's literature. Please be sure to heed the WARNINGS -they
a re extremely important for your safety and
the safety of yo ur passengers, especially in­
fants and small children.
_&. WARNING
N eve r rely on airbags alone for protec tion.
- Even w hen they deploy, airbags provide
only s uppleme ntal pro tect ion .
- Airbag work most effective ly when used
wit h prope rly wor n safety belts .
- Therefore , always wea r you r safety belts
and make sure that eve rybody i n your ve­

_&. WARNING
A pe rs o n on the fron t passe nger seat, es­
pe cial ly inf ants and sm all children, will re­
ceive serio us injuries and can even be kil­
l e d by being too close to the airbag when
it inflates .
- Altho ugh the Advanced Airbag System in
your veh icle is designed to tur n off the

conditions is impossible in all conceiva­
ble situations that may happen during
the useful life of your vehicle.
- The Advanced Airbag System can deploy
in accordance with the "low risk" option
under the U.S. Federal Standard if a child
that is heavier than the typical one-year
old child is on the front passenger seat
and the other conditions for airbag de­
ployment are met.
-Accident statistics have shown that chil­
dren are generally safer in the rear seat
area than in the front seating position.
- For their own safety, all children, espe­
cially 12 years and younger, should al­
ways ride in the back properly restrained
for their age and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was
manufactured.
The front Advanced Airbag System supple­ ments the safety belts to provide additional
protection for the driver's and front passeng­
er's heads and upper bodies in frontal crashes .
The airbags inflate only in frontal impacts
when the vehicle deceleration is high enough.
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts. Rather, it is part of the over­
all occupant restraint system in your vehicle.
Always remember that the airbag system can
only help to protect you, if you are sitting up­
right , wearing your safety belt and wearing it
properly. This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be.
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 very small adults on
the driver side. The low risk deployment crite­
ria are intended to help reduce the risk of in- jury through interaction with the front 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 "suppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are restrained on the front passenger
seat in child restraints that are listed in the Standard
~ page 202, Child restraints and
Advanced Airbags .
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is re­
strained on the front passenger seat in one
of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your vehicle was
certified. For a listing of the child restraints
that were used to certify your vehicle's com­
pliance with the US Safety Standard
~page 202,
-weight less than a threshold level stored in
the control unit is detected on the front pas­
senger seat.
When a person is detected on the front pas­ senger seat, weighing more than the total
weight of a child that is about 1 year old re­
strained in one of the rear-facing 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), the front airbag on the passen­ ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to­
tal weight on the front passenger seat that re­ quires the front airbag to be turned off. If the
PASSENGER AIR BAG OFF light does not
come on, the front airbag on the passenger
side has not been turned off by the control
unit and can deploy if the control unit senses
an impact that meets the conditions stored in
its memory.
ll-

Page 187 of 342

If the total weight on the front passenger
seat is more than that of a typical 1 year -old,
but less than the weight of a small adult, the
front airbag on the passenger side may deploy (the
P ASS ENGER AIR B AG OFF light does not
come on).
For example, th e airbag may depl oy if:
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld safety seats listed
<=) page 202),
-a chi ld who has outgrown child restraints is
on the front passenger seat.
I f the front passenger airbag is turned
off, the
PA SSENGER AIR B AG OFF light in the center
of the instrument panel wi ll come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PA SSENG ER AIR BAG O FF
light does not ill uminate and stay lit) if:
- a small adu lt or teenager is on the front pas­
senger seat
- a passenger who is not sitt ing upright w ith
their back against a non-reclined backrest
with their feet on the vehicle floo r in front
of the seat is on the front passenge r seat .
If the front passenger airbag deploys, the
Federal Standard requires the a irbag to meet
the " low risk" deployment cr iteria to help re ­
duce the risk of inju ry through interaction
with the airbag. "Low risk" deployment occurs in those crashes that take place at lower de­
celerations as defined in the electronic control
un it.

Al ways rememb er: Even tho ugh your vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat. Please be sure to read the impor­
tant information in the sect ions that follow
and be sure to heed all of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag inflates, a lways wear safety belts prope rly.
A irbag system 185
-If you are unrestrained, leaning forward,
sitt ing s ideways or out of pos ition in any
way, your risk of injury is much higher.
- You will a lso receive serious injuries and
could even be killed if you are up aga inst
the airbag or too close to it when it in­
flates -even w ith an Advanced A irbag
<=)page 179.
A WARNING
-
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be ser ious ly injured and can be killed if
the front airbag inflates -even with an Ad­
vanced A irbag System.
- Al tho ugh the Advanced Airbag System in
your veh icle is designed to turn
off the
front airbag when a rearward -facing
child restraint has been insta lled on the
front passenger seat, nobody can abso­
lutely guarantee that dep loyment is im­
possible in all conceivable s ituations that
may happen dur ing the usefu l life of your
veh icle.
- The inflating airbag will h it the ch ild
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the bac krest, center
armrest, doo r, or roof.
- Always install rearward-facing chi ld re­
straints on the rear seat.
- If you must install a rearwa rd fac ing
child safety seat on the fro nt passenger
seat because of exceptiona l circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and s tay on, im ­
mediately insta ll the rear-facing ch ild
safety seat in a rear seating position and
have the airbag system inspected by your
author ized Audi dealer.
A WARNING
If, in except iona l circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:

-Always make sure the forward-facing
seat has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag .
- Never put the forward-facing child re­
straint up aga inst or very near the instru­
ment panel.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before insta lli ng

Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brack­
ets, and more . The fu nction of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on.
The control unit mo nitors the Advanced Air­
bag Sys tem and turns the airbag indicator
light on when a ma lfunction in the system
components is detected . The function of the
ai rbag ind icator light is described in greater
detai l below. Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you must take care to
prevent it from be ing damaged . Damage to
the seat may prevent the Advanced A irbag for
the front passenger seat from doing its job in
a cra sh .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re ve hicle ac celera tion/de ce le ra ti on
to provide info rm ation to the Advanced Air­
bag System abo ut the severity of the crash . -
An elect ronic contro l unit, with integrated
crash sensors for front and side impacts .
The control un it "decides" whether to fi re
the front a irbags based on the informat ion
received from the crash sensors. The contro l
un it also "decides" whether the safety belt
prete nsioners shou ld be act ivated .
- An Advanced A irbag w ith gas generator for
the dr iver inside the stee ring wheel hub .
- An Advanced A irbag w ith gas generator in­
side the instrument panel for the front pas­
senge r.
- A we ight-sensing mat under the up ho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat .
The informat io n registe red is sent continu­
ou sly to the elec troni c con tro l unit to regu ­
la te deployment of the front Advanced Air­
bag on the passenger side .
- An airbag monitoring sys tem and in dicator
light in t he instr ument cluster

you whe n the front Advanced Airbag on the
passenger side has been tu rned off .
- A sensor below the safety be lt latch for the
front seat passenger to meas ure the tension
on the safety be lt . The tension on the safety
be lt and the weight registered by the

be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
dr iver seat from the veh icle .
- Never remove the upholstery from the
front passenger seat .
- Never disassemble or remove parts from
the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or place them on the seat. If the weight­
sensing mat in the passenger seat is
punctured it cannot work properly.
- Never carry things on your lap or carry
objects on the passenger seat . Such
items can increase the weight registered
by the weight-sens ing mat and send the
wrong info rmation to the airbag control
unit.
- Never store items under the front pas­
senger seat. Parts of the Advanced Ai r­
bag System under the passenger seat
cou ld be damaged, preventing them and
the airbag system from working proper ­
ly .
- Never place seat covers or replacement
upholstery that have not been specifical­
ly approved by A udi on the front seats.
- Seat covers can prevent the Advanced
Airbag System from recognizing child re­
straints or occupants on the front pas­
senger seat and prevent the side airbag in the seat backrest from deploy ing prop­
erly.
- Never use cush ions, pillows, blankets or
similar items on the front passenger
seat . The add itional padd ing will prevent
the weight-sens ing mat in the seat from
accu rately reg iste ring the ch ild restra int
or person on the seat and prevent the
Advanced Airbag System from function­ ing properly .

How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide airbags supp lement the protection of­
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head rest raints to help reduce the
risk of inj ury in a wide range of accident and
c rash situations. Be s ure to read the impor­
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need A irbag System
and the activation of the safety belt preten­
sioners depend on the deceleration measured
by the crash sensors and registered by the
electronic control unit. Crash severity depends
on speed and deceleration as we ll as the mass
and stiffness of the veh icle or object involved
in the crash .
When the e lectronic control unit registers a
low severity crash and the safety belt is being
used, the airbag will not deploy. If the safety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat­ er t ime in the crash sequence.
If the electron ic control unit registers a crash
of medium severity , the first stage of the air ­
bag deploys followed by the second stage at a
much later time in the crash sequence -re­
gardless of whether the safety belt is be ing
u sed or not . In higher sever ity crashes as reg­
iste red by the electronic control unit, both the

O n the passenger side, regard less of safety

weight on the passenger seat is less than the
amount prog rammed in the electronic control

will also be turned off if one of the child safe­
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recogn ized on the seat. The

~ WARNING
To reduce the risk of injury when an airbag
inf lates, a lways wear safety belts properly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of inj ury is much higher.
- You wi ll also receive serio us inju ries and
cou ld even be killed if you are up against

More important things to know about
front airbags
F ig. 198 Inflated front a irbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can u nfo ld properly and pro­
vide supplemental protection in a frontal col­ lision. T
he front airbags are designed to provide ad ­
ditional protection for the chest and face of
the driver and the front seat passenger when:
- safety belts are worn properly
- t he seats have bee n positioned so that the
occ upan t is prope rly seated as far as poss i­
b le from the airbag
- and the head restraints have been properly
ad justed
Because airbags inflate in the bli nk of an eye
with great force, th ings you have on your lap
o r have p laced on the seat co uld become dan ­
gerous p ro jecti les, and be p ushed in to you if
the a irbag inflates.
When an airbag deploys, fine dust is re leased.
T h is is no rma l and is not caused by a fire i n
the ve hicle. This dust is made up mos tly of a
powde r used to lubricate the ai rbags as they
deploy.
It could irr itate skin.
It i s impo rtant to remember that wh ile the
s u pplementa l airbag system is designed to re­
duce the like lihood o f se rious injur ies, other
injuries , for examp le swelling, bruising and
minor ab rasions, can also happen when air ­
bags inflate . A irbags do not protect the arms
or the lower parts of the body. Front a irbags
supplement the three-point safety belts only i n some fronta l col lisions in wh ich the vehicle
deceleration is h igh eno ugh to deploy the air­
bags.
Front airbags will not deploy:
- if the ignition is sw itched off when a crash
occurs
- in side co llisions
- in rear-end co llisions
- in rollove rs
- when the crash dece lerat ion meas ured by
the air bag system is less than the min imum
threshold needed for airbag deployment as
reg istered by the elect ronic contro l unit
The front pass enger airbag also w ill not
deploy:
- when the front passenger seat is not occu-
pied .,.
