Airbag System Components
Your vehicle may be equipped with the following airbag
system components:
• Occupant Restraint Controller (ORC)
• Airbag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolster
• Driver Advanced Front Airbag
• Passenger Advanced Front Airbag
• Front Seat Belt Pretensioners, Seat Belt Buckle Switch,
and Seat Track Position Sensors Advanced Front Airbag Features
The Advanced Front Airbag system has multistage driver
and front passenger (if equipped) airbags. This system
provides output appropriate to the severity and type of
collision as determined by the Occupant Restraint Con-
troller (ORC).
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 remaining gas in the inflator is expended.
WARNING!• No objects should be placed over or near the airbag
on the instrument panel, because any such objects
could cause harm if the vehicle is in a collision
severe enough to cause the airbag to inflate.
(Continued)2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 51

The ORC contains a backup power supply system that
may 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 approxi-
mately four to eight 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 startup.
It also includes diagnostics that will illuminate the instru-
ment cluster Airbag Warning Light if a malfunction is
noted that could affect the airbag system. The diagnostics
also record the nature of the malfunction. 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 an authorized dealer service the
airbag system immediately.
Driver and Passenger Airbag Inflator Units
The Driver and Passenger Airbag Inflator Units are
located in the center of the steering wheel and the right
side of the instrument panel (if equipped). When the
ORC detects a collision requiring the Advanced Front
Airbags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the Advanced Front
Airbags. Different airbag inflation rates are possible,
based on the collision type and severity. The steering
wheel hub trim cover and the upper right side of the 2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 55

normally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot coolant to
enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
• Do not overfill the coolant recovery bottle.
• Check engine coolant (antifreeze) freeze point in the
radiator and in the coolant recovery bottle. If engine
coolant (antifreeze) needs to be added, contents of
coolant recovery bottle must also be protected against
freezing.
• If frequent engine coolant (antifreeze) additions are
required, or if the level in the coolant recovery bottle
does not drop when the engine cools, the cooling
system should be pressure tested for leaks. • Maintain engine coolant (antifreeze) concentration at
50% HOAT engine coolant (antifreeze) (minimum)
and distilled water for proper corrosion protection of
your engine, which contains aluminum components.
• Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean, also.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze) per-
formance, poor gas mileage, and increased emissions.
7 MAINTAINING YOUR VEHICLE 397

EMISSIONS CONTROL SYSTEM MAINTENANCE
The Scheduled Maintenance services listed in bold type
must be done at the times or mileages specified to ensure
the continued proper functioning of the emissions control
system. These and all other maintenance services in-
cluded in this manual, should be done to provide best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions, such as dusty areas and very short trip
driving.
Inspection and service should also be done anytime a
malfunction is suspected.
NOTE: Maintenance, replacement or repair of the emis-
sions control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part that has been
certified pursuant to U.S. EPA or in the State of Califor-
nia, California Air Resources Board regulations. MAINTENANCE SCHEDULE
5.7L Gas Engine
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
On Electronic Vehicle Information Center (EVIC)
equipped vehicles, “Oil Change Due” will be displayed
in the EVIC and a single chime will sound, indicating that
an oil change is necessary.
On Non-EVIC equipped vehicles, “Change Oil” will flash
in the instrument cluster odometer and a single chime
will sound, indicating that an oil change is necessary.
Based on engine operation conditions the oil change
indicator message will illuminate, this means that service
is required for your vehicle. Have your vehicle serviced
as soon as possible, within the next 500 miles (805 km).
