WARNING LIGHTS AND CHIMES

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: The service
engine soon indicator
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
indicator 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 indicator 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 indicator 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.
