Listed are four situations you may experience with your f~~el gage:
At the gas station. the fuel pump shuts off before the gage reads full.
It lakes a little more or less fuel to fill up than the fuel gage indicated.
For example, the gage may have indicated the tank was half
full, but it
actually took a little more or less than half the tank's capacity to fill the
, tank.
The gage moves a little when you turn a corner or speed up.
The gage doesn't go back to empty when you turn off the ignition.
None of these indicate
a problem with the fuel gage.
For information on how to fill your fuel tank, see "Fuel - Filling Your
Tank"
in the Index.
For your fuel tank capacity, see "Fuel -Tank Capacity" in the Index.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. Most of the time. the gage
pointer
will show your coolant temperature at 2 10°F (99"C), or less. But, if
you are pulling a heavy load or driving LIP hills, your coolant temperature
may rise and
fall near the red 260°F ( 128°C) mark. This is normal. If the
gage pointer moves to the red 260°F
(128°C) mark, your engine is too hot!
It means that your engine coolant has overheated. You should pull off the
road,
stop your vehicle. and turn off the engine as soon as possible.
Hot Coolant Can Burn You Badly!
In "Problems on the Road," this manual shows what to do. See "Engine
Overheating"
in thc Index.

Voltmeter
When your engine is not running. but the ignition is in the RUN position.
this
gage shows your battery’s state of charge in DC volts.
When the engine is running, the gage shows the condition
of the charging
system. Readings between the low and high wat-ning
zones indicate the
normal operating range.
Readings
in the low warning zone may occur when a large number of
electrical accessories are operating in the vehicle and the engine is left at an
idle for an extended period. This condilion is normal since the charging
system is
not able to provide full power at engine idlc. As engine speeds are
increased, this condition should correct itself
;IS higher engine speeds allow
the charging system
to create nwximum power.
You can only drive For a short time with the reading in either warning zone.
If you must drive, turn off all unnecessary accessories.
Readings
in either warning zone indicate a possible problcm in the electrical
system. Have the vehicle serviced
as soon as possible.
