as a check to let you know that the light is working.

come on, the bulb may be burned out. See your dealer
for assistance in changing the bulb.
If the light does not go out or if the light comes on

Engine Coolant Temperature Gage

That reading means the same thing as the warning
light — the engine coolant is very hot. See Engine
Overheating on page 5-29 .
This gage shows
the engine coolant
temperature. If the
gage pointer moves
into the shaded area,
the engine is too hot.
