Coolant selection
Only use “Toyota Super Long Life Coolant” or a 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. (Minimum temperature: -35C [-31F])
For more details about coolant, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
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 Lexus dealer or repairer, or
another duly qualified and equipped professional test the cap and check for
leaks in the cooling system.
CAUTION
When the hybrid system is hot
Do not remove the engine/power control unit coolant reservoir caps.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.

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 any authorized
Lexus dealer or repairer, or another duly qualified and equipped
professional.
CAUTION
When the hybrid system is hot
Do not touch the radiator or condenser as they may be hot and cause serious
injuries, such as burns.

Do not touch the engine compartment.
The electric cooling fans may keep rotating for about 3 minutes even after
the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. Be sure the “POWER” switch is off when working near the
electric cooling fans or radiator grille.
