NOTICE
z Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
z Do not continue driving with an
overheated engine. See ”If your
vehicle overheats” in Part 4.
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.
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
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.
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.
Your vehicle may overheat during severe
operating conditions, such as:
NOTICE
D Driving up a long hill on a hot day.
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.
D Reducing speed or stopping after high
speed driving.
D Idling for a long period with the air
conditioning on in stop−and−go traffic.
