ESCRIPTIONS
1. Tachometer

Indicates the engine speed in revolutions
per minute (RPM x 1000).
2. Voltmeter

When the engine is running, the gauge indi -
cates 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 contin -
uous high or low reading under normal driving
conditions may indicate a lubrication system
malfunction. Immediate service should be
obtained from an authorized dealer.
4. Speedometer

Indicates vehicle speed.
5. Temperature Gauge

The temperature gauge shows engine
coolant temperature. Any reading within the
normal range indicates that the engine
cooling system is operating satisfactorily.

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.
6. Instrument Cluster Display

When the appropriate conditions exist, this
display shows the instrument cluster
display messages

page 92.
7. 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.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. It is recommended to call an authorized
dealer for service if your vehicle overheats
Ú
page 296.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge
reads “H,” pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until
the pointer drops back into the normal range. If
the pointer remains on the “H,” turn the engine
off immediately and call an authorized dealer for
service.
