Premium Instrument Cluster Descriptions
1. Tachometer
Indicates the engine speed in revolutions

per minute (RPM x 1000).
2. Voltmeter
When the engine is running, the gauge

indicates the electrical system voltage.
The pointer should stay within the normal
range if the battery is charged. If the
pointer moves to either extreme left or
right and remains there during normal
driving, the electrical system should be
serviced.
NOTE:
The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling oper-
ation is caused by the post-heat cycle of the
intake manifold heater system. The number of
cycles and the length of the cycling operation is
controlled by the engine control module.
Post-heat operation can run for several
minutes, and then the electrical system and
voltmeter needle will stabilize.
3. Oil Pressure Gauge
The pointer should always indicate some

oil pressure when the engine is running.
A continuous high or low reading under
normal driving conditions may indicate a
lubrication system malfunction. Imme-
diate service should be obtained from an
authorized dealer.
4. Speedometer
Indicates vehicle speed.

5. Fuel Gauge
The fuel gauge shows the level of fuel in

the fuel tank when the ignition is in the
ON/RUN position.
The fuel pump symbol points

to the side of the vehicle where
the fuel door is located.
Refer to "Refueling The Vehicle — Gas
Engine" in "Starting And Operating" for
further information.

6. Instrument Cluster Display
When the appropriate conditions exist,

this display shows the instrument cluster
display messages. Refer to "Instrument
Cluster Display" in this chapter for further
information.
7. Temperature Gauge
The temperature gauge shows engine

coolant temperature. Any reading within
the normal range indicates that the
engine cooling system is operating satis-
factorily.
The pointer will likely indicate a higher

temperature when driving in hot weather,
up mountain grades, or when towing a
trailer. It should not be allowed to exceed
the upper limits of the normal operating
range.
