How The Airbag System Works
•
TheOccupant Restraint Control (ORC) Modulede-
termines if a frontal collision is severe enough to
require the airbags to inflate. The front airbag inflators
are designed to provide different rates of airbag infla-
tion from direction provided by the ORC. The ORC
may also modify the rate of inflation based on theoccupant size provided by the Occupant Classification
Module. The ORC will not detect roll over, or rear
impacts.
The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
key is in the LOCK position, in the ACC position, or
not in the ignition, the airbags are not on and will not
inflate.
Also, the ORC turns on the “Airbag Warning
Light” and “PAD Indicator Light” for 6 to 8
seconds for a self-check when the ignition is
first turned on. After the self-check, the
“Airbag Warning Light” will turn off. The “PAD
Indicator Light” will function normally (Refer toPas-
senger Airbag Disable (PAD) Indicator Lightin this

objects are placed on the seat, the passenger airbag
will not inflate even though the “PAD Indicator Light”
is not illuminated.
The “PAD Indicator Light” should not be illuminated
when teenagers, most children in a forward-facing
child restraint or booster seats, most children that canproperly wear the vehicle’s seat belt, and when an
adult passenger is properly seated in the front passen-
ger seat. In this case, the airbag is ready to be inflated
if a collision requiring an airbag occurs.
For almost all properly installed rear facing child re-
straints, the “PAD Indicator Light” will be illuminated
indicating that the front passenger airbag is turned off
and will not inflate. If the “PAD Indicator Light” is not
illuminated,DO NOTassume the airbag is turned off
and move the child restraint to the rear seat. A deploying
passenger airbag can cause death or serious injury to a
child in a rear facing infant seat.
NOTE:Even though this vehicle is equipped with an
Occupant Classification System, children 12 years and
under should always ride buckled up in a rear seat in an
appropriate child restraint.

airbag gas is vented through the vent holes in the sides
of the airbag. In this way, the airbags do not interfere
with your control of the vehicle.
•TheOccupant Classification Module (OCM)is lo-
cated beneath the front passenger seat. The OCM
classifies the occupant into categories based on the
measurements made by the seat weight sensors. The
OCM communicates with the Occupant Restraint Con-
trol (ORC) Module. The ORC uses the occupant cat-
egory to determine whether the front passenger airbag
should be turned off. It also determines the rate of
airbag inflation during a collision.
•Your vehicle has fourWeight Sensorslocated between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
•TheSide Impact SRS Side Curtain Airbagsare de-
signed to activate only in certain side collisions. Whenthe ORC (with side impact option) detects a collision
requiring the side curtain airbag to inflate, it signals
the inflators on the crash side of the vehicle. A quantity
of nontoxic gas is generated to inflate the side curtain
airbag. The inflating side curtain airbag pushes the
outside edge of the headliner out of the way and
covers the window. The airbag inflates in about 30
milliseconds (about one quarter of the time it takes to
blink your eyes) with enough force to injure you if you
are not belted and seated properly, or if items are
positioned in the area where the side curtain airbag
inflates. This especially applies to children. The side
curtain airbag is only about 3
12inches (9 cm) thick
when it is inflated.
•TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.

•As the airbags deflate you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the nontoxic gas used for airbag
inflation. These airborne particles may irritate the skin,
eyes, nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles settle on your
clothing, follow the garment manufacturer’s instruc-
tions for cleaning.
•It is not advisable to drive your vehicle after the
airbags have deployed. If you are involved in another
collision, the airbags will not be in place to protect you.
WARNING!
Deployed airbags and seat belt pretensioners cannot
protect you in another collision. Have the airbags,
seat belt pretensioner, and seat belt retractor assem-
bly, replaced by an authorized dealer as soon as
possible. Also, have the Occupant Classification
System serviced as well.
Enhanced Accident Response Feature
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately 5 seconds after the vehicle has stopped
moving, the interior lights will illuminate to aid visibility.
NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.

Child Restraint
Everyone in your vehicle needs to be buckled up all the
time — babies and children, too. Every state in the United
States and all Canadian provinces require that small
children ride in proper restraint systems. This is the law,
and you can be prosecuted for ignoring it.
Children 12 years and under should ride properly buck-
led up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats rather than in the front.
There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult safety belt. Always check the child
seat Owner’s Manual to ensure you have the right seat
for your child. Use the restraint that is correct for your
child:

WARNING!
In a collision, an unrestrained child, even a tiny
baby, can become a missile inside the vehicle. The
force required to hold even an infant on your lap can
become so great that you could not hold the child, no
matter how strong you are. The child and others
could be badly injured. Any child riding in your
vehicle should be in a proper restraint for the child’s
size.
Infants and Child Restraints
•
Safety experts recommend that children ride
rearward-facing in the vehicle until they are at least
one year oldandweigh at least 20 lbs (9 kg). Two types
of child restraints can be used rearward-facing: infant
carriers and “convertible” child seats.
•The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children who weigh up
to about 20 lbs (9 kg). “Convertible” child seats often
have a higher weight limit in the rearward-facing
direction than infant carriers do, so they can be used
rearward-facing by children who weigh more than 20
lbs (9 kg) but are less than one year old. Both types of
child restraints are held in the vehicle by the lap/
shoulder belt or the LATCH child restraint anchorage
system (Refer to LATCH — Child Seat Anchorage
System in this section.)
•Rearward-facing child seats mustNEVERbe used in
the front seat of a vehicle with the front passenger
airbag unless the airbag is turned off. An airbag
deployment could cause severe injury or death to
infants in this position.
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
•Improper installation can lead to failure of an
infant or child restraint. It could come loose in a
collision. The child could be badly injured or
killed. Follow the manufacturer’s directions ex-
actly when installing an infant or child restraint.
•A rearward facing infant restraint should only be
used in a rear seat. A rearward facing infant
restraint in the front seat may be struck by a
deploying passenger airbag which may cause se-
vere or fatal injury to the infant.
Here are some tips for getting the most out of your child
restraint:
•Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable SafetyStandards. The manufacturer also recommends that
you try a child restraint in the vehicle seats where you
will use it before you buy it.
•The restraint must be appropriate for your child’s
weight and height. Check the label on the restraint for
weight and height limits.
•Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
•Except for the second row center seating position, all
passenger seat belts are equipped with cinching latch
plates. The second row center position has an auto-
matic locking retractor identified by a distinctive label.
Both types of seat belts are designed to keep the lap
portion tight around the child restraint so that it is not
necessary to use a locking clip. If the seat belt has a
cinching latch plate, pulling up on the shoulder por-
tion of the lap/shoulder belt will tighten the belt (the
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 55

cinching latch plate will keep the belt tight, however,
any seat belt system will loosen with time, so check the
belt occasionally and pull it tight if necessary). For the
second row center seat belt with the automatic locking
retractor, pull the belt from the retractor until there is
enough to allow you to pass through the child restraint
and slide the latch plate into the buckle. Then, pull the
belt until it is fully extracted from the retractor. Allow
the belt to return to the retractor, pulling on the excess
webbing to tighten the lap portion about the child
restraint. For additional information, refer toAuto-
matic Locking Modeearlier in this section.
•In the rear seat, you may have trouble tightening the
lap/shoulder belt on the child restraint because the
buckle or latch plate is too close to the belt path
opening on the restraint. Disconnect the latch plate
from the buckle and twist the short buckle-end belt
several times to shorten it. Insert the latch plate into
the buckle with the release button facing out.
•If the belt still cannot be tightened, or if pulling and
pushing on the restraint loosens the belt, disconnect
the latch plate from the buckle, turn the buckle
around, and insert the latch plate into the buckle
again. If you still cannot make the child restraint
secure, try a different seating position.
•Buckle the child into the restraint exactly as the
manufacturer’s instructions tell you.
•When your child restraint is not in use, secure it in the
vehicle with the seat belt or remove it from the vehicle.
Do not leave it loose in the vehicle. In a sudden stop or
collision, it could strike the occupants or seat backs
and cause serious personal injury.
