AVENSIS_OM_OM20B88E_(EE)
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 (especially a tie, a scarf or a muffler) away from
the fan and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
Do not loosen 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.
If the fan is not operating: 
Stop the engine immediately and contact any authorized
Toyota dealer or repairer, or another duly qualified and
equipped professional.
If the fan is operating: 
Have the vehicle inspected at the nearest authorized
Toyota dealer or repairer, or another duly qualified and
equipped professional.STEP7
