WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid
death or serious injury, observe the following precautions.
■ When working on the engine compartment
● Keep hands, clothing and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel on the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
● Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately.
If you still experience discomfort, consult a doctor.
■ When working near the electric cooling fan or radiator grille
Vehicles without a smart entry & start system
Be sure the engine switch is in the “LOCK” position.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( P. 375)
Vehicles with a smart entry & start system
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( P. 375)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.

Start the engine and turn the air conditioning system on to check
that the radiator cooling fan operates and to check for coolant leaks
from the radiator or hoses.
The fan operates when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fan is 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 fan may not operate in freezing temperatures.)
If the fan is not operating:
Stop the engine immediately and contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
If the fan is operating:
Have the vehicle inspected at the nearest authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
