OCCUPANT RESTRAINTS
Some of the most important safety features in your
vehicle are the restraint systems. These include the front
and rear seat belts for the driver and all passengers, front
airbags for both the driver and front passenger, and if
equipped, left and right window bags for the driver and
passengers seated next to a window and a driver inflat-
able knee blocker. If you will be carrying children too
small for adult-size seat belts, your seat belts or the
LATCH feature (refer to the Child Restraint section in this
manual), can be used to hold infant and child restraint
systems.
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.

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.
•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 andcolumn, 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.

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
12inches (9 cm) thick when it
is inflated.
•When the ORC and the impact sensors detect a
collision requiring theDriver Inflatable Knee
Blocker,it signals the inflator unit. A quantity of
nontoxic gas is generated to inflate the Driver Inflat-
able 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 inter-
action 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.
•TheKnee Impact Bolstershelp 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 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.
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 isOFF 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 climate controls.)

•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 (OCS) detects either an
empty seat of a weight less than the predetermined
occupant threshold, the ORC will not illuminate the
PAD indicator light even though the airbag is turned
off. When the OCS detects an adult the PAD indicator
light will be off, and the airbag will be enabled.
•TheBelt Tension Sensor (BTS)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.
•TheBladder Assemblyis 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.

WARNING!
•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 airbags.
Airbag Light
You will want to have the airbags ready to
inflate for your protection in a collision. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system immediately.
•The AIRBAG light does not come on or flickers during
the 6 to 8 seconds when the ignition switch is first
turned on.
•The light remains on or flickers after the 6 to 8 second
interval.
•The light flickers or comes on and remains on while
driving.
NOTE:If the speedometer, tachometer or any engine
related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready
to inflate for your protection. Promptly check fuse block
for blown fuses. Refer to the label located on the inside of
the fuse block cover for the proper airbag fuses. See your
dealer if the fuse is good.
Event Data Recorder (EDR)
In the event of an airbag deployment, your vehicle is
designed to record up to 2-seconds of specific vehicle
data parameters (see list below) in an event data recorder
prior to the moment of airbag deployment. Please note
that such data are ONLY recorded if an airbag deploys,
and are otherwise unavailable. In conjunction with other

Data Parameters that May Be Recorded:
•Diagnostic trouble code(s) and warning lamp status
for electronically-controlled safety systems, including
the airbag system
•Airbag disable lamp status (if equipped)
•Timeof airbag deployment (in terms of ignition
cycles and vehicle mileage)
•Airbag deployment level (if applicable)
•Seat belt status
•Brake status (service and parking brakes)
•Accelerator status (including vehicle speed)
•Engine control status (including engine speed)
•Cruise control status
•Traction/stability control status
Child Restraint
Everyone in your vehicle needs to be buckled up at all
times — 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 seat appropriate for their age and size.
According to crash statistics, children are safer when
properly restrained in the rear seats, rather than in the
front.
