Maintenance and care
■Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
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% deion-
ized water. (Minimum temperature: -35 C [-31F])
For more details about coolant, contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine and intercooler coolant reservoir
caps, drain cock and water pump.
If you cannot find a leak, have any authorized Toyota retailer or Toyota autho-
rized repairer, or any reli able repairer test the cap and check for leaks in the
cooling system.
WARNING
■ When the engine is hot
Do not remove the radiator cap, engine coolant filler cap or intercooler cool-
ant 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.
NOTICE
■ When adding 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.

WARNING
■To prevent an accident or injury when inspecting under the hood of
your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
● 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.
● Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fan and belts while the engine is operating.
● Do not loosen the radiator cap, the engine coolant filler cap or the inter-
cooler coolant reservoir cap while the engine and radiator are hot.
NOTICE
■ When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
■ To prevent damage to the cooling system
Observe the following precautions.
● Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
● Do not use any coolant additives.
