Coolant selection
Only use “TOYOTA Genuine 50/50 Pre-mixed Super Long Life Coolant
BLUE” or similar high-quality ethylene glycol-based non-silicate, non-amine,
non-nitrite, and non-borate coolant with long-life hybrid organic acid technol-
ogy.
“TOYOTA Genuine 50/50 Pre-mixed Super Long Life Coolant BLUE” is a
mixture of 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.
CAUTION
When the engine is hot
Do not remove the radiator cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
NOTICE
When adding engine coolant
Coolant is neither plain water nor straight 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 it from damaging parts or paint.

If you observe the following, your vehicle may be overheating.
The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
Steam is coming from under the hood.
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 away from the fan and other belts while the
