Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause extensive 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
bulbs work. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.

Service engine soon: The service
engine soon indicator 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 the Readiness for Inspection/Maintenance (I/M)
testing in the Maintenance and Specifications chapter.
Solid illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer to On
board diagnostics (OBD-II) in the Maintenance 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 contact your authorized dealer
as soon as possible.
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.
Check fuel fill inlet (if
equipped): Illuminates when the
fuel fill inlet may not be properly
closed. Continued driving with this
light on may cause the service
engine soon warning light to come
on. Refer to Easy Fuel™ “no cap” fuel system in the Maintenance and
Specifications chapter.
Brake system warning light: To
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

the risk of personal injury.

to illuminate when the ignition is
turned to on, continues to flash or
remains on, contact your authorized

your safety belt. A Belt-Minder威
chime will also sound to remind you
to fasten your safety belt. Refer to
the Seating and Safety Restraints
chapter to activate/deactivate the Belt-Minder威 chime feature.
