Maintenance and care
LX570_OM_OM60L21U_(U) Engine coolant
The coolant level is satisfactory if it is between the “F” and “L” lines on the
reservoir when the engine is cold.
Reservoir cap
“F”
“L” If the level is on or below the “L”
line, add coolant up to the “F” line.
■
If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, reservoir cap, radiator cap, 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. ■
Coolant selection
Only use “Toyota Super Long Life Coolant” or 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%
deionized water. (Enabled: -31 F [-35 C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45%
deionized water. (Enabled: -44 F [-42 C])
For more details about engine coolant, contact your Lexus dealer.

LX570_OM_OM60L21U_(U) Radiator and condenser
Check the radiator and condenser, and clear any foreign objects.
If any of the above parts are extremely dirty or you are not sure of their
condition, have your vehicle checked by your Lexus dealer. CAUTION■
When the engine is hot
Do not remove the 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 engine 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 damage to parts or paint.
CAUTION■
When the engine is hot
Do not touch the radiator or condenser, as they may be hot and cause serious inju-
ries, such as burns.

LX570_OM_OM60L21U_(U) CAUTION■
When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage painted
surfaces. If fluid gets in your eyes, flush your eyes with clean water immediately. If
you still experience discomfort, see a doctor.
NOTICE■
If the fluid level is low
It is normal for the brake fluid level to go down slightly as the brake pads wear or
when the fluid level in the accumulator is high.
If the reservoir needs frequent refilli ng, it may indicate a serious problem.
