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.
Note: Some warning lights are
reconfigurable telltale (RTT)
indicator lights and will illuminate in
the message center. These lights
function the same as the other
warning lights.
Service engine soon: The
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.
