INFORMATION

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.
U.S.A.: "Toyota Super Long Life Coolant" is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -31°F [-35°C])
Canada: "Toyota Super Long Life Coolant" is a mixture of 55% coolant and 45%
deionized water. (Minimum temperature: -44°F [-42°C])
For more details about coolant, contact your Lexus dealer.
■
If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine/power control unit coolant reservoir caps,
drain cock and water pump.
If you cannot find a leak, have your Lexus dealer test the cap and check for leaks in the
cooling system.
WARNING
When the hybrid system is hot, do not remove the engine coolant reservoir cap or power
control unit 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.
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.
Checking the radiator and condenser
Check the radiator and condenser and clear away any foreign objects.
If either of the above parts is extremely dirty or you are not sure of their condition,
have your vehicle inspected by your Lexus dealer.
