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 the
proper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC maymodify the rate of inflation based on the occupant size
provided by the Occupant Classification Module. The
ORC will not detect 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, and knee bolsters. 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 warning light
(located in the instrument cluster) and PAD indicator
light (located in the front passenger grab handle) 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

If there is a fault present in the system, the AIRBAG
warning light will light indicating that you should
take the vehicle to an authorized dealer. In the pres-
ence of an occupant in the passenger seat, if both the
PAD indicator light (located in the front passenger
grab handle) and AIRBAG warning light (located in
the instrument cluster) are illuminated 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 grab
handle in front of the passenger seat.)For almost all sizes of properly seated adults, the passen-
ger frontal 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 indica-
tion if the front passenger is properly positioned or not. If
the PAD indicator light comes on when an adult is in the
passenger seat, have the passenger re-position them-
selves in the seat until the light goes out. Remember, if
the PAD indicator light is illuminated the passenger front
airbag will not inflate. For properly installed child re-
straint systems and children properly seated on the front
passenger seat, the airbag will be disabled. If at all
possible, place children 12 years and younger in a back
seat.
•TheOccupant Classification Module (OCM)is lo-
cated beneath the front passenger seat. The OCM
classifies the occupant into one of three size categories
based on the input from the Bladder Assembly and a
Belt Tension Sensor. The size categories include empty,child, and adult. The OCM sends the Occupant Clas-
sification to the ORC to determine if a front passenger
airbag is allowed. If a fault is present, the AIRBAG
warning light is illuminated.
•ThePassenger Airbag Disabled (PAD) Indicator
Lightindicates 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 Occu-
pant Classification System detects either an empty seat
or a weight less than the predetermined threshold, the
ORC will not illuminate the PAD indicator light even
though the airbag is turned OFF.

Enhanced Accident Response System (E.A.R.S.)
If the airbags deploy after an impact and the electrical
system remains functional, the interior lights will turn on
and the power door locks (if equipped) will unlock 5
seconds after airbag deployment.
Also, the fuel system will shut off immediately upon
airbag deployment (gasoline models only). The ignition
switch will need to be cycled (i.e. turn the ignition key
from the ON position to the LOCK position) after ap-
proximately 5 seconds in order to restart the vehicle.

Also, the light will come on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
If the parking brake is off and the light remains on, have
the brake system inspected as soon as possible.
19. Full Time Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the FULL TIME four–wheel drive mode, and
employs the inter-axle differential which al-
lows the front and rear wheels to rotate at
different speeds. (See page 236 for more information.)
20. Sentry Key/Security Alarm Indicator Light — If
Equipped
Refer to “Sentry Key Immobilizer System” or “Vehicle
Security Alarm” in Section 2 of this manual for more
information.21. Fuel Gage
When the ignition key is in the ON position, the pointer
will show the level of fuel remaining in the fuel tank. A
small arrow indicates the side of the vehicle where the
filler cap (gas cap) is located.
22. Low Fuel Warning Light
When the fuel level reaches approximately 2.3 U.S.
Gallons (8.7 Liters) this light will come on and
remain on until fuel is added. The “Low Fuel
Warning Light” may turn on and off again, especially
during and after hard braking, accelerations, or turns.
This occurs due to the shifting of the fuel in the tank.
Also, a single chime will sound.
23. Airbag Warning Light
This indicator lights and remains lit for 6 to 8
seconds when the ignition is first turned on. If the
light doesn’t come on, stays on, or comes on while driving,
have the airbag system checked by an authorized dealer.
