NOTICE
■Application of coatings to the vehicle body (GS F)
Do not apply any kind of coating to the vehicle body as doing so may damage the paint
or reduce its durability.
■To prevent paint deterioration and corrosion on the body and components (aluminum
wheels etc.)
●Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar, pollen or tree sap is present on the paint surface
• If dead insects, insect droppings or bird droppings are present on the paint surface
• After driving in an area contaminated wi th soot, oily smoke, mine dust, iron pow-
der or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gaso line are spilled on the paint surface
●If the paint is chipped or scratched, have it repaired immediately.
●To prevent the wheels from corroding, remove any dirt and store in a place with low
humidity when storing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic substances or scrub with a hard brush.
This may damage the surfaces of the lights.
●Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
■When using an automatic car wash (vehicles with rain-sensing windshield wipers)
Turn off AUTO mode of the wiper to prevent the wiper from operating. ( →P. 2 74 )
If AUTO mode is selected, the wipers may operate and the wiper blades may be dam-
aged.
■When using a high-pressure car wash
●When washing the vehicle, do not let water from the high-pressure washer directly hit
the camera or the area around the camera. Due to the shock from high-pressure
water, it is possible that the device may not operate normally.
●Do not bring the nozzle tip close to boots (rubber or resin manufactured cover), con-
nectors or the following parts. The parts may be damaged if they come into contact
with high-pressure water.
• Traction related parts
•Suspension parts •Steering parts
•Brake parts
●GS F: Do not point the nozzle of a high pres-
sure washer at the areas shown in the illustra-
tion, as high pressure water may damage the
oil coolers.

■Intercooler coolant reservoir (GS200t only)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 9 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.
“Toyota Super Long Life Coolant” is a mixt ure 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 coolant reservoir 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 sys-
tem.

■When the engine is hot
Do not remove the engine coolant reservoi r cap, the intercooler coolant reservoir cap
or the coolant inlet cap. ( →P. 6 0 0 )
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.
