GAUGES
Fuel gauge
Displays approximately how much
fuel is in the fuel tank (when the
key is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion or after
refueling. The ignition should be in
the OFF position while the vehicle is
being refueled. When the gauge first
indicates empty, there is a small
amount of reserve fuel in the tank.
When refueling the vehicle from an empty indication, the amount of fuel
that can be added will be less than the advertised capacity due to the
reserve fuel.
Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the ªHº and ªCº). If it
enters the red section, the engine is
overheating. Stop the vehicle as
soon as safely possible, switch off
the engine immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
carechapter.

OPERATING THE ENGINE
Do not operate the engine at full throttle below peak torque engine
speed (RPM) for more than one minute at a time (peak torque RPM
varies from 1200-1500 RPM depending on engine rated speed).
Monitor the oil pressure and coolant
temperature gauges frequently.
If the gauges indicate any reading is
not in the normal operating range,
stop your vehicle as soon as possible,
shut the engine off and check the
appropriate fluid level. If an
overheating condition starts to occur,
release the throttle pressure or shift
the transmission into a lower gear, or
both, until the temperature returns
to normal operating range.
Continuous operation with low coolant
temperature, below 60ÉC (140ÉF) or
high coolant temperature 100ÉC
(212ÉF) can damage the engine.
Most failures give some kind of early
warning. Look and listen for changes
in performance, sound or engine
appearance that can indicate service
or engine repair is needed. Some
changes to look and/or listen for:
²Engine misfires
²Loss of power
²Sudden changes in engine operating temperature or oil pressure
²Excessive smoke
²Fuel, oil or coolant leaks
²Vibration
²Increased oil or fuel consumption
Excessive full throttle operation below peak torque RPM will shorten
engine life to overhaul and can cause serious engine damage. Operation
of the engine below peak torque RPM can occur during gear shifting due
to difference of gear ratios.
