Q 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 mix-
ture of 50% coolant and 50% deionized
water. (Minimum temperature: -35°C [-
31°F])
For more details about coolant, contact any
authorized Lexus retailer or Lexus autho-
rized repairer, or any reliable repairer.
Q 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 autho-
rized Lexus retailer or Lexus authorized
repairer, or any reliable repairer, test the
cap and check for leaks in the cooling sys-
tem.

Q When the hybrid system is hot
Do not remove the engine/power con-
trol unit coolant reservoir caps or the
coolant inlet cap. (P.451)
The cooling system may be under pres-
sure and may spray hot coolant if the cap
is removed, causing serious injuries, such
as burns.
Q 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.
Q If you spill coolant
Be sure to wash it off with water to pre-
vent it from damaging parts or paint.
