Overheating
If you observe the following, your vehicle may be overheating:
●The high engine coolant temperature warning light flashes or comes on
or a loss of power is experienced.
● Steam comes out from under the hood.
CAUTION
■To prevent an accident or injury when inspecting under the hood of
your vehicle
●If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injuries such as burns.
● Keep hands and clothing away from the fan and drive belt while the engine
is running.
● Do not loosen the radiator cap while the engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam

sary.
Water can be used in an emer-
gency if engine coolant is
unavailable. ( P. 347)
Have the vehicle inspected at the nearest Toyota dealer as soon as
