FORD 2002 Ranger v.2 - Manual (Page 10)

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 solid:
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 without these or
any other temporary malfunctions present, the light should turn off. (A
driving cycle consists of a cold engine startup followed by mixed
city/highway driving.) No additional vehicle service is required.
If the light remains on, have your vehicle serviced at the first available opportunity.
