TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (rpm). Do not rev the
engine into the red zone

CAUTION
When engine speed approaches the red
zone, reduce engine speed. Operating the
engine in the red zone may cause serious
engine damage.

illustration.
The engine coolant temperature varies with
the outside air temperature and driving con-
ditions.
CAUTION
If the gauge indicates coolant temperature
near the hot (H) end of the normal range,
reduce vehicle speed to decrease tempera-
ture. If the gauge is over the normal range,
stop the vehicle as soon as safely possible. If
the engine is overheated, continued opera-
tion of the vehicle may seriously damage
the engine. For additional information, re-
fer to “If your vehicle overheats” in the “In
