■Coolant selection
Only use “Toyota Super Long Life Cool-
ant” 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/power control unit coolant reser-
voir caps, drain cock and water pump. If you cannot find a leak, have any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer, test the cap and check for leaks in the cooling system.
WARNING
■When the hybrid system is hot
Do not remove the engine/power con-
trol unit coolant reservoir caps. ( P.483)
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 mix- ture of water and antifreeze must be used to provide proper lubrication,
corrosion protection and cooling. Be sure to read the antifreeze or coolant label.

Do not touch the radiator or con-
denser as they may be hot and cause serious injuries, such as burns.
Adding the washer fluid

etc.
NOTICE
■Do not use any fluid other than
washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces, as well as damaging the pump leading to prob-
lems of the washer fluid not spraying.
■Diluting washer fluid
Dilute washer fluid with water as nec- essary.Refer to the freezing temperatures
listed on the label of the washer fluid bottle.
