•
The tachometer indicates engine speed in revo-
lutions per minute.
•
If the needle enters the red zone , the engine
is overrevved. Reduce the vehicle speed suffi-
ciently during downhill driving or downshifting to
keep the needle from entering this zone.
P. 7-11
CAUTION
The term “overrev” refers to rotation of the
engine at an RPM exceeding the maximum limit.
This occurs when the engine is driven by the
wheels during downhill driving or downshifting.
Persistent overrevving can lead to an engine
breakdown.
This gauge indicates the temperature of the engine
coolant.
With the engine running normally, the needle should
be in the center of the scale.
If the needle enters the red zone , the engine has
overheated. The warning lamp will illuminate at
this time. In this event, pull off the road as soon as
you can safely do so then let the engine cool down
by running it at a speed slightly higher than its idling
speed. If the vehicle has an air conditioner, switch it
off.
When the gauge needle comes down to approxi-
mately the center of the scale, stop the engine and
perform the checks and corrective steps described
on this reference page: P. 13-8
CAUTION
Be sure to stop the engine only after letting it
run at a speed slightly above the idling RPM
until the coolant cools down. Turning off the
engine immediately after stopping will cause the
coolant temperature to rise quickly and may
cause the engine to seize up.
