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. 460)
● 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 Coolant” or similar high quality eth-
ylene glycol based non-silicate, non- amine, 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.

If a large amount of coolant leaks,
immediately contact any autho-
rized Toyota dealer or repairer, or
another duly qualified and
equipped professional.
The coolant level is satisfactory if
it is between the “FULL” and

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 fan operates and to check for
coolant leaks from the radiator or hoses.
The fan operates when the air conditioning system is turned on
immediately 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 professional.

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.
● When the electric cooling fan may operate even after the engine has been
stopped (diesel engine only).
 P. 445
● 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.
