If the fan is not operating:
Stop the engine immediately and call any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radia-
tor) for any leaks.

If you observe the following, your vehicle may be overheating:
Vehicles without a multi-information display: The high engine coolant tem-
perature warning light comes on or a loss of power is experienced.
Vehicles with a multi-information display: The high engine coolant tempera-
ture gauge enters the red zone or a loss of power is experienced.
Steam comes out from under the hood.
CAUTION
