WARNING!
•Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won’t deploy at all.
Always wear your seat belts even though you
have airbags.
•Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.
•If the vehicle has window bags, they also need
room to inflate. Do not lean against the door or
window. Sit upright in the center of the seat.

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

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.
•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 toinflate the front airbags. Different airbag inflation rates
may be possible based on collision severity and occu-
pant 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
is about 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’s front airbag gas is vented through vent
holes in the sides of the airbag. The passenger’s front
airbag gas is vented through vent holes in the sides of
the airbag. In this way the airbags do not interfere with
your control of the vehicle.
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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

56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.

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, vehicle body structure, or add aftermar-
ket side steps or running boards.
•Do not attempt to modify any part of your advanced airbag
system. The airbag may inflate accidentally or may not
function properly if modifications 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, 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, con-
tact your authorized dealer.
WARNING!
•You need proper knee impact protection in a colli-
sion. Do not mount or locate any aftermarket equip-
ment 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.
Airbag Warning Light
You will want to have the airbag system ready to inflate for
your protection in an impact. The airbag system is designed
to be maintenance free. If any of the following occurs, have
an authorized dealer service the system promptly:
•Does not come on during the 6 to 8 seconds after the
ignition switch is first turned on.
•Remains on after the 6 to 8 second interval.
•Comes on for any period of time while driving.
62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

garage, and never sit in a parked vehicle with the
engine running for a extended period. If the vehicle is
stopped in an open area with engine running for more
than a short period, adjust the ventilation system to
force fresh, outside air into the vehicle.
•Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
•Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside ve-
hicle. Otherwise poisonous gases could be drawn into
the vehicle.
Safety Checks You Should Make Inside The
Vehicle
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.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
pretensioners, etc.). If there is any question regarding belt
or retractor condition, replace the belt.
NOTE:The “Seat Belt Indicator Light” will remain on
until the driver’s seat belt is buckled.
Airbag Warning 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 bulb is not lit during starting, have the
system checked by an authorized dealer.
74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Defrosters
Check operation by selecting the defrost mode and place
the blower control on high speed. You should feel the air
directed against the windshield.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect for tread cuts or sidewall
cracks. Check wheel nuts for tightness and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of all exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
coolant, oil or other fluid leaks. Also, if gasoline fumes
are detected, the cause should be located and corrected
immediately.
