Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to
check that the radiator cooling fans operate and to check for
coolant leaks from the radiator or hoses.
The fans operate when the air conditioning system is turned on
immediately after a cold start. Confirm that the fans are operating by
checking the fan sound and air flow. If it is difficult to check these,
turn the air conditioning system on and off repeatedly.
(The fans may not operate in freezing temperatures.)
If the fans are not operating:
Stop the engine immediately and contact your Toyota dealer.
If the fans are operating:
Have the vehicle inspected at the nearest Toyota dealer.

WARNING
■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 (especially a tie, a scarf or a muffler) away from
the fans and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
● Do not loosen the radiator cap and the 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.
