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, have
the respective system inspected immediately.
Check engine
Illuminates briefly to ensure the
system is functional. If it comes on
after the engine is started, one of
the engine's emission control
systems may be malfunctioning. The
light may illuminate without a driveability concern being noted and will
not require towing.
Light turns on (without blinking):
Temporary malfunctions may cause your light to illuminate. Examples
are:
1. The vehicle has run out of fuel.
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the fuel cap. After three driving cycles
