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 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 have your vehicle serviced
immediately by your authorized dealer.
