40 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Control Module
•Airbag Warning Light
•Driver Airbag
•Passenger Airbag
•Side Curtain Airbags above Side Windows (If
Equipped)
•Side Remote Acceleration Sensors (If Equipped)
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Knee Impact Bolsters
•Front Acceleration Sensors
•Driver and Front Passenger Seat Belt Pretensioner
•Occupant Classification System (OCS) — Front Pas-
senger Seat Only (If Equipped)
Occupant Classification Module
Passenger Airbag Disable (PAD) Indicator Light
Weight Sensors
How The Airbag System Works
•
TheOccupant Restraint Control (ORC) Modulede-
termines if a frontal, side, or rollover collision is severe
enough to require the front and/or side airbags to
inflate. The front airbag inflators are designed to
provide different rates of airbag inflation from direc-
tion provided by the ORC. The ORC may also modify
the rate of inflation based on the occupant size pro-
vided by the Occupant Classification Module. The
ORC will detect roll overs, not rear impacts.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 47

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
section). If the ORC detects a malfunction in any part
of the system, it turns on the “Airbag Warning Light”either momentarily or continuously. A single chime
will sound if the light comes on again after initial start
up.
WARNING!
Ignoring the “Airbag Warning Light” in your instru-
ment panel could mean you won’t have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
•TheOccupant Classification System (OCS) (If
Equipped)is part of a Federally regulated safety
system required for this vehicle. It is designed to turn
off the front passenger airbag in the unlikely event that
a rear-facing infant seat is in the front passenger seat.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The OCS classifies an occupant using weight sensors
mounted in the base of the front passenger seat. Any
weight on the seat will be sensed by the system. Objects
hanging on the seat or other passengers pushing down
on the seat will also be sensed. The weight of an adult
will cause the system to turn the airbag on. In this case,
the OCS has classified the occupant of the seat as an
adult. An adult occupant needs to sit in a normal position
(with their feet on or near the floor) in order to be
properly classified. Reclining the seat back too far may
change how an occupant is classified by the OCS.
Drivers and adult passengers should verify that the
“PAD Indicator Light” is not illuminated when an adult
is riding in the front passenger seat. If an adult occu-
pant’s weight is transferred to another part of the vehicle
(like the door or instrument panel), the weight sensors in
the seat may not properly classify the occupant. Objects
lodged under the seat or between the seat and the center
console can prevent the occupant’s weight from beingmeasured properly and may result in the occupant being
improperly classified. Ensure that the front passenger
seat back does not touch anything placed on the back seat
because this can also affect occupant classification. Also,
if you fold down the rear seat check to be sure it doesn’t
touch the front passenger seat.
If the front passenger seat is damaged in any way, it
should only be serviced by an authorized dealer. If the
seat is removed (or even if the seat attachment bolts are
loosened or tightened in any way), take the vehicle to an
authorized dealer.
If there is a fault present in the OCS, the “Airbag Warning
Light” (a red light located in the center of the instrument
cluster directly in front of the driver) will be turned on.
This indicates that you should take the vehicle to an
authorized dealer. The “Airbag Warning Light” is turned
on whenever there is fault that can affect the operation of
the airbag system. If there is a fault present in the OCS,
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 51

both the “PAD Indicator Light” and the “Airbag Warning
Light” are illuminated to show that the passenger airbag
is turned off until the fault is cleared. If an object is
lodged under the seat and interferes with operation of
the weight sensors, a fault will occur which turns on both
the “PAD Indicator Light” and the “Airbag Warning
Light.” Once the lodged object is removed, the fault will
be automatically cleared after a short period of time.
•TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
are possible, based on collision severity and occupant
size. The steering wheel hub trim cover and the upper
right side of the instrument panel separate and fold
out of the way as the bags inflate to their full size. The
bags fully inflate in about 50–70 milliseconds. This isabout half of the time it takes to blink your eyes. The
bags then quickly deflate while helping to restrain the
driver and front passenger.
The driver front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger front
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.
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
Maintaining Your Airbag System
WARNING!
•Modifications to any part of the airbag system could cause it to fail
when you need it. You could be injured if the airbag system is not
there to protect you. Do not modify the components or wiring,
including adding any kind of badges or stickers to the steering
wheel hub trim cover or the upper right side of the instrument
panel. Do not modify the front bumper or vehicle body structure.
•Do not attempt to modify any part of your advanced airbag system. The
airbag may inflate accidentally or may not function properly if modi-
fications are made. Take your vehicle to an authorized dealer for any
advanced airbag system service. If your seat including your trim cover
and cushion needs to be serviced in any way (including removal or
loosening/tightening of seat attachment bolts), take the vehicle to your
authorized dealer. Only manufacturer approved seat accessories may
be used. If it is necessary to modify an advanced airbag system for
persons with disabilities, contact your authorized dealer.
•Do not place or hang any items such as add-on video players on the
right front passenger seat back. The additional weight may cause
the Occupant Classification System to be unable to correctly classify
the right front occupant. This could allow the passenger frontal
airbag to inflate when it is not desired.
•You need proper knee impact protection in a collision. Do not mount or
locate any aftermarket equipment on or behind the knee bolsters.
•It is dangerous to try to repair any part of the airbag system yourself.
Be sure to tell anyone who works on your vehicle that it has an
airbag system.
