If your vehicle overheats
If your engine overheats:
Stop the vehicle in a safe place and turn off the air condi-
tioning system.
Check to see if steam is coming out from under the hood.
If you see steam: Stop the engine. Carefully lift the hood after the steam
subsides and then restart the engine.
If you do not see steam: Leave the engine running and carefully lift the hood.
Remove the engine compartment cover. ( P. 331)
Check to see if the cooling fan is operating.
If the fan is operating: Wait until the engine coolant temperature gauge begins
to fall and then stop the engine.
If the fan is not operating: Stop the engine immediately and call your local Toyota
dealer.
After the engine has cooled
down sufficiently, check the
coolant level and inspect the
radiator core (radiator) for any
leaks.STEP1

Overheating
In the following situations, your vehicle may be overheating.
● The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
● Steam is coming 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 injury such as burns.
● Keep hands and clothing away from the fan and engine 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
released under pressure.
Add coolant if required.
Water can be used in an emer-
gency measure if coolant is
unavailable. ( P. 435)
Have the vehicle checked at your nearest Toyota dealer as soon as
possible.
