■Engine coolant reservoir
The coolant level is satisfactory if it is between the “FULL” and “LOW” lines on
the reservoir when the engine is cold. Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the “LOW” lin e, add coolant up to the “FULL” line.
(  P. 5 1 6 )
■Intercooler coolant reservoir (IS200t only)
The coolant level is satisfactory if it is between the “F” and “L” lines on the res-
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. 5 1 6 )
■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])

ure 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, hoses, engine coolant reservoir 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.
Check the radiator, condense r and intercooler radiator (if equipped) and clear
away any foreign objects.
If any of the above parts are extremely dirty or you are not sure of their condition,
have your vehicle inspected by your Lexus dealer.
CAUTION
■When the engine is hot
Do not remove the engine coolant reservoir cap, radiator cap (IS350/IS300) or inter-
cooler coolant reservoir cap (IS200t). ( P. 5 1 9 )
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)
CAUTION
■When the engine is hot
Do not touch the radiator, condenser or inte rcooler radiator (if equipped) as they may
be hot and cause serious injuries, such as burns.

■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
Fluid type SAE J1703 or FMVSS No.116 DOT 3 brake fluid
ItemsClean funnel
CAUTION
■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 eyes, flush the affected area with clean water
immediately.
If you still experience discomfort, 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 refil ling, there may be a serious problem.
