FRONT SEAT AIRBAG FEATURES
The front airbag system has dual-stage driver and front
passenger airbags. This system provides output appro-
priate to the level of crash severity as determined by the
Occupant Restraint Controller (ORC) and the impact
sensors at the front of the car. The first stage inflator is triggered immediately during an
impact that requires airbag deployment. The timing of
the second stage determines whether the output force is
low, medium, or high. If a low output is sufficient to meet
the need, the second stage is expended later in the crash
event.
Driver Airbag Special Features
Driver airbag deployment and force level is controlled by
the driver's seat position as well as impact severity. Use
of special inflators, result in a very compact driver's side
airbag.
In addition to the small size, the inflating gasses exit
through strategically placed vents, which direct the gas
away from the occupant. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 53

Supplemental Side Airbag Inflatable Curtain
(SABIC) Ð If Equipped
Supplemental Side Airbag Inflatable Curtain (SABIC)
Airbags offer side-impact protection to front and rear seat
outboard occupants in addition to that provided by the
body structure. Each airbag features inflated chambers
place adjacent to the head of each outboard occupant that
reduce the potential for side-impact head injuries. The
curtains deploy downward, covering both windows on
the impact side.
NOTE: Airbag covers may not be obvious in the interior
trim; but they will open to allow airbag deployment.
The system includes sensors adjacent to both front and
rear seat occupants that are calibrated to deploy the side
bags during an impact severe enough to require airbag
occupant protection. Side Airbag Inflatable Curtains (SABIC) Location THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 55

AIRBAG DEPLOYMENT SENSORS AND
CONTROLS
Occupant Restraint Controller (ORC)
The Occupant Restraint Controller System (ORC) is
part of a Federally regulated safety system required for
this vehicle.
The ORC determines if a frontal collision is severe
enough to require the airbags to inflate. Based on the
sensor signals, a central electronic Occupant Restraint
Controller (ORC) deploys the front airbags, side inflat-
able airbag curtains (if equipped), seat-mounted side
(Thorax) airbags (if equipped), and front seat belt preten-
sioners as required for each type of impact.
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 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.
The ORC contains a backup power supply system that
will deploy the airbags even if the battery loses power or
it becomes disconnected prior to deployment.
Also, the ORC turns on the Airbag Warning
Light in 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. 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.
It also includes diagnostics that will illuminate the instru-
ment cluster Airbag Warning Light if a malfunction is
noted. The diagnostics also record the nature of the
malfunction. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59

WARNING!Ignoring the AIRBAG light in your instrument 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.
Impact Sensors
Two sensors, located on the front body structure, trigger
airbag deployment in direct frontal impacts and aid the
Occupant Restraint Controller (ORC) in determining
appropriate response to frontal impact events. Additional
sensors in the ORC determine the level of airbag deploy-
ment and provide deployment verification. Side Inflatable Curtain and Front Seat Mounted
Airbags Ð If equipped
The Occupant Restraint Controller System (ORC) de-
ploys the side inflatable curtain and seat mounted thorax
side airbags during collision with other vehicles and
during collisions where the impact is confined to a
particular area of the vehicle Ð such as collisions with
poles, trees or similar objects.
It will deploy the side inflatable curtains and front seat
thorax mounted airbags only on the impact side of the
vehicle.
The front driver and passenger seat contain inflatable
side airbags to protect the occupant from impact injuries.
Correctly functioning front passenger seat components
are critical for the Occupant Restraint Controller System60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
² The AIRBAG light does not come on during the 6 to 8
seconds when the ignition switch is first turned on.
² The light remains on after the 6 to 8 second interval.
² The light comes on and remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) 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 accident, your vehicle is designed to
record up to 5 seconds of specific vehicle data parameters
(see the following list) in an event data recorder prior to
the moment of airbag deployment, or near deployment,
and up to a quarter second of high-speed deceleration
data during and/or after airbag deployment. EDR data
are ONLY recorded if an airbag deploys, or nearly
deploys, and are otherwise unavailable.
NOTE:
1. A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually indica-
tive of a crash, but not severe enough to warrant airbag
deployment.
2. Under certain circumstances, EDR data may not be
recorded (e.g., loss of battery power).
In conjunction with other data gathered during a com-
plete accident investigation, the electronic data may be THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65

POWER SUNROOF Ð IF EQUIPPED
The sunroof controls are mounted between the sun visors
in the Dome/Reading Lamp.
WARNING!² Never leave children in a vehicle, with the keys in
the ignition switch. Occupants, particularly unat-
tended children, can become entrapped by the
power sunroof while operating the power sunroof
switch. Such entrapment may result in serious
injury or death.
² In an accident, there is greater risk of being
thrown from a vehicle with an open sunroof. You
could also be seriously injured or killed. Always
fasten your seat belt properly and make sure all
passengers are properly secured too.
² Do not allow small children to operate the sun-
roof. Never allow fingers or other body parts, or
any object to project through the sunroof opening.
Injury may result.Power Sunroof Switch1 - Left Interior Light 3 - ATC Sensor - If Equipped

CAUTION!The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
(Refer to ªTire Inflation Pressuresº under ªTires Ð Gen-
eral Informationº and to ªTire Pressure Monitor System
(TPMS)º in Section 5 of this manual for more informa-
tion). 25. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors emissions, engine, and
automatic transaxle control systems. The light
will illuminate when the key is in the ON/RUN position
before engine start. If the bulb does not come on when
turning the key from LOCK/OFF to ON/RUN, have the
condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations the vehicle will drive normally and will
not require towing.
If the Malfunction Indicator Light flashes when the
engine is running, serious conditions may exist that178 UNDERSTANDING YOUR INSTRUMENT PANEL

4. Press and release the RESET button and the ªCALº
indicator will quit flashing.
5. Drive the vehicle slowly, completing one or more
circles (in an area free from large metal or metallic
objects) until the ªCALº indicator turns off. The compass
will now function normally.
Compass Variance
Compass Variance is the difference between magnetic
North and Geographic North. In some areas of the
country, the difference between magnetic and geographic
North is great enough to cause the compass to give false
readings. If this occurs, the compass variance must be set
using the following procedure:
NOTE: Magnetic materials and cell phones should be
kept away from the top of the Instrument Panel. This is
where the compass sensor is located. UNDERSTANDING YOUR INSTRUMENT PANEL 187

cabin infrared sensor mounted between the sun-visors
and from various sensors located throughout the vehicle.
The controls on the climate control provide the system
with operator input. Other sensors take account of ve-
hicle speed, A/C pressure, outside temperature, and
engine cooling temperature. Using all of these inputs, the
system automatically adjusts airflow temperature, air-
flow distribution, airflow volume, and the amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.
Operation of the system is quite simple.
1. Turn the Mode Control knob (on the right) and the
Blower Control knob (on the left) to AUTO.
NOTE: The AUTO position performs best for front seat
occupants only. 2. Dial in the temperature you would
like the system to maintain by rotating
the Temperature Control knob.
Once the comfort level is selected, the system will main-
tain that level automatically using the heating system.
Should the desired comfort level require air conditioning,
the system will automatically make the adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the ªOº (Off) position on the blower control stops the
system completely and closes the outside air intake.
72ÉF (22ÉC) is the recommended setting for maximum
comfort for the average person; however, this may vary. UNDERSTANDING YOUR INSTRUMENT PANEL 247
