Features of your vehicle
When the door is open, or if the engine is
not started within 1 minute, the tachome-
ter pointer may move slightly in ON posi-
tion with the engine OFF. This movement
is normal and will not affect the accuracy
of the tachometer once the engine is run-
ning.
CAUTION
Do not operate the engine within
the tachometer's RED ZONE.
This may cause severe engine dam-
age.

Engine temperature gauge
This gauge shows the temperature of the
engine coolant when the ignition switch
is ON.
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to "If the engine overheats" in section 6.
CAUTION
If the gauge pointer moves beyond
the normal range area toward the
"H" position, it indicates overheat-
ing that may damage the engine.
WARNING
Never remove the radiator cap
when the engine is hot. The engine
coolant is under pressure and
could cause severe burns. Wait
until the engine is cool before
adding coolant to the reservoir.
