WARNING LIGHTS AND CHIMES
Standard instrument cluster
Optional instrument cluster
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.

Service Engine Soon:TheService
Engine Soonindicator light
illuminates when the ignition is first
turned to the on position to check
the bulb and to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing. Normally, the “Service engine
soon” light will stay on until the engine is cranked, then turn itself off if
no malfunctions are present. However, if after 15 seconds the “Service
engine soon” light blinks eight times, it means that the vehicle is not
ready for I/M testing. See theReadiness for Inspection/Maintenance
(I/M) testingin theMaintenance and Specificationschapter.
Solid illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer toOn
board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately by your authorized dealer.
WARNING:Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.
Powertrain malfunction
indicator (if equipped):
Illuminates when a powertrain fault
has been detected. Contact your
authorized dealer as soon as possible.
Check fuel cap (if equipped):
Illuminates when the fuel cap may
not be properly installed. Continued
driving with this light on may cause
the Service engine soon warning
light to come on. Refer toFuel
filler capin theMaintenance and Specificationschapter.

confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the on position
when the engine is not running, or in a position between on and start, or
by applying the parking brake when the ignition is turned to the on
position. If the brake system warning light does not illuminate at this
time, seek service immediately from your authorized dealer. Illumination
after releasing the parking brake indicates low brake fluid level and the
brake system should be inspected immediately by your authorized dealer.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.
Airbag readiness:If this light fails
to illuminate when the ignition is
turned to on, continues to flash or
remains on, have the system
serviced immediately by your authorized dealer. A chime will sound
when there is a malfunction in the indicator light.
Safety belt:Reminds you to fasten
your safety belt. A Belt-Minder

chime will also sound to remind you
to fasten your safety belt. Refer to
