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 or rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulphuric 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, see a doctor.
■ When working near the electric cooling fan or radiator grille
● Vehicles without 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
temperature is high. ( P. 454)

WARNING
■ When working near the electric cooling fan or radiator grille
● Vehicles with smart entry & start system: Be sure the “ENGINE START
STOP” switch is off.
With the “ENGINE START STOP” switch in IGNITION ON mode, the elec-
tric cooling fan may automatically start to run if the air conditioning is on
and/or the coolant temperature is high. ( P. 454)
● Diesel engine only: After the temperature in the engine compartment has
become high, the electric cooling fan may operate even after the engine
has been stopped.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
NOTICE
■ If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
■ If the brake fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

■ If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, reservoir cap, radiator cap, drain cock
and water pump.
If you cannot find a leak, have any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional, test the cap and check for
leaks in the cooling system.
■ Coolant selection
Gasoline engine
Only use “Toyota Super Long Life C oolant” or similar high quality ethyl-
ene glycol based non-silicate, non-am ine, non-nitrite, and non-borate
coolant with long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50%
deionized water. (Enabled: -35 C [-31F])
Diesel engine
Only use “Toyota Genuine Premium Long Life Coolant 1WW/2WW” or
equivalent.
“Toyota Genuine Premium Long Life Coolant 1WW/2WW” is pre-mixed
with 50% coolant and 50% deionized water. (Enabled: -35 C [-31F])
For more details about engine coolant, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
WARNING
■ When the engine is hot
Do not remove the coolant reservoir cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.

Radiator, condenser and intercooler
Check the radiator, condenser and intercooler (diesel engine only)
and clear any foreign objects.
If any of the above parts are extremely dirty or you are not sure of
their condition, have your vehicle checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
NOTICE
■ When adding engine coolant
Coolant is neither plain water nor stra ight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
■ If you spill coolant
Be sure to wash it off with water to prevent damage to parts or paint.
WARNING
■ When the engine is hot
Do not touch the radiator, condenser or intercooler, as they may be hot and
cause serious injuries, such as burns.
■ When the electric cooling fan may operate even after the engine has
been stopped (diesel engine only)
