The gauge indicates the engine coolant
temperature when the ignition switch is
on. The engine operating temperature
will vary with changes in weather and
engine load.
If the needle moves into the red zone, your
engine is too hot. If your vehicle overheats,
stop your vehicle and allow the engine to
cool.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
Idling for a long period with the air con-
ditioning on in stop-and-go traffic.
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to
control the flow of coolant to keep
the temperature of the engine
within the specified operating
range.
Do not continue driving with an
overheated engine. See “If your
vehicle overheats” in Part 4.
The tachometer indicates engine
speed in thousands of rpm (revolu-
tions per minute). Use it while driving
to select correct shift points and to
prevent engine lugging and overrev-
ving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.
