If your vehicle is equipped with the Occupant Classifi-
cation System (OCS) there will be a Passenger Airbag
Disabled (PAD) Indicator Light located on the center of
the instrument panel.
NOTE: The front airbags have a multi stage inflator
design. This allows the airbag to have different rates of
inflation that are based on collision severity.
Please pay close attention to the information in this
section. It tells you how to use your restraint system
properly to keep you and your passengers as safe as
possible.WARNING!
In a collision, you and your passengers can suffer
much greater injuries if you are not properly buck-
led up. You can strike the interior of your vehicle or
other passengers, or you can be thrown out of the
vehicle. Always be sure you and others in your
vehicle are buckled up properly.
Buckle up even though you are an excellent driver, even
on short trips. Someone on the road may be a poor driver
and cause a collision that includes you. This can happen
far away from home or on your own street.
Research has shown that seat belts save lives, and they
can reduce the seriousness of injuries in a collision. Some
of the worst injuries happen when people are thrown
from the vehicle. Seat belts reduce the possibility ofPassenger Airbag Disabled Light

How The Airbag System Works
•
The Occupant 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 the
proper 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.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
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 window bag
inflates. This especially applies to children. The win-
dow bag is only about 3
1 2inches (9 cm) thick when it
is inflated.
•When the ORC and the side impact sensors (with side
impact option) detects a collision requiring the Driver
Inflatable Knee Blocker, it signals the inflator unit. A
quantity of nontoxic gas is generated to inflate the
Driver Inflatable Knee Blocker. The Driver Inflatable
Knee Blocker inflates rearward towards the driver’s
knees to help protect the knees and position you for
the best interaction with the front airbag. The Driver
Inflatable Knee Blocker fully inflates in about 50
milliseconds, this is only about half of the time it takes
you to blink your eyes. It then quickly deflates while
helping to protect the driver’s knees.
•The Knee Impact Bolsters help protect the knees, and
position everyone for the best interaction with the
front airbag.
•If your vehicle contains a Passenger Airbag Disable
indicator light, it will be equipped with the Occupant
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.)

•ThePassenger Airbag Disabled (PAD) Indicator
Light — If Equipped indicates 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 is
turned OFF. When the OCS system detects an adult the
PAD indicator light will be off, and the airbag will be
enabled.
•The Belt Tension Sensor (BTS) — If Equipped is
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.
•The Bladder Assembly — If Equipped is 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
(OCS) to properly classify the front passenger and calcu-
late the proper airbag deployment. Do not make any
modifications to the front passenger seat components,
assembly, or to the seat cover.
