The engine coolant temperature varies with the
outside air temperature and driving conditions.
CAUTION
If the gauge indicates the engine coolant tem-
perature is near the hot (H) end of the normal
range, reduce vehicle speed to decrease the
temperature. If the gauge is over the normal
range, stop the vehicle as soon as safely pos-
sible and let the engine idle. If the engine is
overheated, continued operation of the vehicle
may seriously damage the engine. See “IF
