How The Airbag System Works
•
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collision
severity, the front control module determines theproper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation.
•The ORC may modify the rate of inflation based on the
occupant size provided by the Occupant Classification
Module.
•The ORC will not detect side, roll over, or rear impacts.
•The ORC monitors the readiness of the electronic parts
of the system whenever the ignition switch is in the
START or RUN positions. These include all of the
items listed above except the steering wheel and
column, instrument panel and passenger knee bol-
sters. If the key is in the OFF 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 warn-
ing light and PAD indicator light in the
center of the instrument panel 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 to“Passenger Airbag
Disable (PAD) Indicator Light”in this section). If the
ORC detects a malfunction in any part of the system, it
turns on the AIRBAG warning light either momen-
tarily 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.
•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 and
impact sensors detects a collision requiring the air-
bags, it signals the inflator units. A large quantity of
nontoxic gas is generated to inflate the front airbags.
Different airbag inflation rates may be 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 airbags inflate to their full size. The airbags fully
inflate in about 50–70 milliseconds. This is about half
of the time it takes to blink your eyes. The airbags then
quickly deflate while helping to restrain the driver and
front passenger.
The driver’s and passenger’s front airbag gas is vented
through the airbag material towards the instrument
panel. In this way the airbags do not interfere with
your control of the vehicle.

•If your vehicle contains a Passenger Airbag Disable
indicator light, it will be equipped with theOccupant
Classification System (OCS).The OCS system will
classify an occupant into a size category based on
sensor readings from within the seat cushion. Occu-
pants should try to remain in a normally seated
position. If the occupant’s weight is transferred to
another object in the vehicle (i.e. feet on the dash-
board), the OCS may not be able to properly approxi-
mate occupant size. Furthermore, the occupant size
may appear to increase or decrease due to objects
hanging on the seat, other passengers pushing on the
seat, or objects lodged underneath the seat. 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 there is a rapid change in temperature or humidity,
the OCS may not be able to properly approximate
occupant size. If your seat including your trim cover
and cushion needs to be serviced in any way (includ-
ing removal or loosening/tightening of seat attach-
ment bolts), take the vehicle to your authorized dealer.
Only manufacturer approved seat accessories may be
used.
If there is a fault present in the system, the AIRBAG
warning light will illuminate indicating that you should
take the vehicle to an authorized dealer. In the presence
of an occupant in the passenger seat, if both the PAD
indicator light and AIRBAG warning light are illumi-
nated the airbag will be disabled.
The ORC will not allow front airbag deployment in the
event of a collision for occupants classified into the
empty or child size categories. The PAD indicator light
will illuminate indicating that the Passenger Airbag is

OFF when the OCS has determined that the occupant size
category is a child. Also, when the seat is empty or an
object that weighs less than a predetermined threshold is
placed on the seat, the light will remain OFF. (The PAD
indicator light is an amber light located on the center of
the instrument panel above the radio.)
For almost all sizes of properly seated adults, the airbag
will be enabled in the event of a collision. For small
teenagers and some small adults, depending on size, the
airbag may or may not be enabled in the event of a
collision. Both drivers and passengers should always use
the PAD indicator light as an indication if the frontpassenger is properly positioned or not. If the PAD
indicator light comes on when an adult is in the passen-
ger seat, have the passenger re-position themselves in the
seat until the light goes out.
Remember, if the PAD indicator light is illuminated the
passenger front airbag will not inflate. For almost all
properly installed child restraints, the“PAD Indicator
Light”will be illuminated indicating that the front pas-
senger airbag is turned off and will not inflate. If the
“PAD Indicator Light”is not illuminated, DO NOT
assume 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.

•TheOccupant Classification Module (OCM)—If
Equippedis located beneath the front passenger seat.
The OCM classifies the occupant into one of three size
categories based on the input from the Bladder Assem-
bly and Belt Tension Sensor. The size categories in-
clude empty, child, and adult. The OCM sends the
Occupant Classification to the ORC to identify if a
front passenger airbag is allowed. If a fault is present,
the AIRBAG warning light is illuminated.
•ThePassenger Airbag Disabled (PAD) Indicator
Light—If Equippedindicates to the driver and
passenger when the airbag is turned OFF in the
presence of a properly seated occupant. When the PAD
indicator light is illuminated, the airbag is OFF. Also,
when the Occupant Classification System detects ei-
ther an empty seat or a weight less than the predeter-
mined occupant threshold, the ORC will not illumi-
nate the PAD indicator light even though the airbag isturned OFF. When the ocs system detects an adult the
PAD indicator light will be off, and the airbag will be
enabled.
•TheBelt Tension Sensor (BTS)—If Equippedis
located at the outboard passenger lap belt anchor. The
BTS generates a signal based on outboard lap belt
tension. This signal is sent to the OCM to ensure that
the resultant bladder pressure increase due to applied
lap belt tension does not cause a small occupant to be
classified as a larger occupant.
•TheBladder Assembly—If Equippedis located
beneath the seat cushion foam. The pressure sensor
sends a signal to the OCM.
The front passenger seat assembly contains critical com-
ponents that affect the front passenger airbag deploy-
ment. Correctly functioning front passenger seat compo-
nents are critical for the Occupant Classification System

•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, seat belt pretensioners and driver
inflatable knee blocker cannot protect you in an-
other collision. Have the airbags, seat belt preten-
sioners, driver inflatable knee blocker and the front
passenger seat belt retractor assembly, replaced by
an authorized dealer as soon as possible. Also, have
the Occupant Classification System serviced as well.
Enhanced Accident Response
If the airbags and seat belt pertensioners deploy after an
impact and the electrical system remains functional,
vehicles equipped with power door locks will unlock
automatically. In addition, approximately 10 seconds
after the vehicle has stopped moving, the interior lights
will illuminate until the ignition switch is turned off.

Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced aftera collision if they have been damaged (bent retractor, torn
webbing, etc. If there is any question regarding belt or
retractor condition, replace the belt.
Airbag Light
The light should come on and remain on for 6
to 8 seconds as a bulb check when the ignition
switch is first turned ON. If the LED is not lit
during starting, have it checked. If the light
stays on or comes on while driving, have the system
checked by an authorized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield.
