A certain amount of engine oil will be consumed while driving. In the following situations,
oil consumption may increase, and engine oil may need to be refilled in between oil
maintenance intervals.
●When the engine is new, for example directly after purchasing the vehicle or after
replacing the engine
●If low quality oil or oil of an inappropriate viscosity is used
●When driving at high engine speeds or with a heavy load, or when driving while accel-
erating or decelerating frequently
●When leaving the engine idling for a long time, or when driving frequently through
heavy traffic

ervoir when the engine is cold.
Reservoir cap
“F” line
“L” line
If the level is on or below the “L” line,
add coolant up to the “F” line.
(→ P. 630)
■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 mixt ure of 50% coolant and 50% deionized water.
(Minimum temperature: -31 °F [-35 °C])
Canada:
“Toyota Super Long Life Cool ant” is a mixture of 55% coolant and 45% deionized water.
(Minimum temperature: -44° F [-42°C])
For more details about engine coolant, contact your Lexus dealer.
■If the coolant level drops within a short time of replenishing
Visually check the radiator, ho ses, engine and intercooler coolant reservoir caps, drain
cock and water pump.
If you cannot find a leak, have your Lexus de aler test the cap and check for leaks in the
cooling system.

Maintenance and care
Check the radiator, condenser and intercooler radiator and clear away any for-
eign objects.
If any of the above parts are extremely dirt y or you are not sure of their condition,
have your vehicle inspecte d by your Lexus dealer.
WARNING
■When the engine is hot (RC350/RC300/RC200t)
Do not remove the engine coolant reservoir cap, intercooler coolant reservoir cap and
radiator cap. ( →P. 634)
The cooling system may be under pressure and may spray hot coolant if the cap is
removed, causing serious injuries, such as burns.
■When the engine is hot (RC F)
Do not remove the engine coolant reservoir cap. (→P. 634)
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 cool-
ing. 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.
Radiator, condenser and intercooler radiator (if equipped)
WARNING
■When the engine is hot
Do not touch the radiator, condenser or inte rcooler as they may be hot and cause seri-
ous injuries, such as burns.

5127-3. Do-it-yourself maintenance
■Checking fluid level
The brake fluid level should be between the “MAX” and “MIN” lines on the
tank.
■Adding fluid
Make sure to check the fluid type and prepare the necessary items.
■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking efficiency. Use
only newly opened brake fluid.
Brake fluid
RC350/RC300/RC200tRC F
Fluid type SAE J1703 or FMVSS No.116 DOT 3 brake fluid
Items Clean funnel
WARNING
■When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damage painted surfaces.
If fluid gets on your hands or in your ey es, flush the affected area with clean water
immediately.
If you still experience di scomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear out or
when the fluid level in the accumulator is high.
If the reservoir needs frequent ref illing, there may be a serious problem.
