sides and then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Check to see if the cooling fan is operating.

instrument panel) begins to fall and then stop the engine.
If the fan is not operating:

■Overheating
If you observe the following, your vehicle may be overheating:
● The engine coolant temperature gauge enters the red zone 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, or coolant reservoir cap while the engine
and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable.
( P. 639)
Have the vehicle inspected at the nearest Toyota dealer as soon as
possible.
