■Instrument panel brightness adjustment
The instrument panel brightness levels when th e tail lights are on and off can be adjusted
individually. However, when the surroundings ar e bright (daytime, etc.), turning on the tail
lights will not change the in strument panel brightness.
■Dimming the analog speedometer lighting
The analog speedometer lighting will be dimme d when the ambient light is bright, such
as during the daytime, and SPORT S or SPORT S+ mode is selected.
■Outside temperature display
●In the following situations, the correct outside temperature may not be displayed, or the
display may take longer than normal to change.
• When stopped, or driving at low speeds (less than 20 km/h [12 mph])
• When the outside temperature has changed suddenly (at the entrance/exit of a garage, tunnel, etc.)
●When “ ” or “E” is displayed, the sy stem may be malfunctioning.
Take your vehicle to any authorized Lexus de aler or repairer, or another duly qualified
and equipped professional.
■Pop-up display
●In some situations, such as when a switch operation is performed, a pop-up display will
be temporarily displayed on the multi-information display.
●Some pop-up displays can be set on/off. ( P. 148)
■Liquid crystal display
Small spots or light spots may appear on th e display. This phenomenon is characteristic
of liquid crystal displays, and there is no problem continuing to use the display.
■Customization
The meter display can be customized on the multi-information display. (P. 139)
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator of the tachometer enter the red zone, as it represents the
engine speed range which exceeds the maximum safe engine speed.
●In the following situations, the engine may be overheating. In this case, immediately
stop the vehicle in a safe place, and check the engine after it has cooled completely.
(  P. 659)
• The engine coolant temperature gauge indicator ( ) is in the red zone and flash- ing.
• The engine oil temperature gauge indicator ( ) is in the red zone and flashing.

■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Lexus recommends that maintenance service operations as well as ot her inspections and repairs be carried out by authorized Lexus dealers or repairers or other duly qualified and equipped profes-
sionals. For repairs and services covered by your warranty, please visit an authorized Lexus dealer or repairer, who will use genuine Lexus parts in repairing any difficulties youmay encounter. There can also be advantages in utilizing authorized Lexus dealers or
repairers for non-warranty repa irs and services, as members of the Lexus network will be able to expertly assist you with any difficulties you may encounter.
Your Lexus dealer or repairer, or another duly qualified and equipped professional will
perform all of the scheduled maintenance on your vehicle reliably and economically due to their experience with Lexus vehicles.
■Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs that indicate service is needed. Some important clues are:
●Engine missing, stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (However, water dripping from the air conditioning sys-
tem after use is normal.)
●Change in exhaust sound (This may indicate a dangerous carbon monoxide leak. Drive with the windows open and have the exhaust system checked immediately.)
●Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
●Vehicle pulls to one side when driven straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches the floor,vehicle pulls to one side when braking
●Engine coolant temperature continually higher than normal ( P. 118, 124)
If you notice any of these clues, take your vehicle to any authorized Lexus dealer or repairer, or another duly qualified and equipp ed professional as soon as possible. Your vehicle may need adjustment or repair.
WARNING
■If your vehicle is not properly maintained
Improper maintenance could result in serious damage to the vehicle and possible death or serious injury.
■Handling of the battery
Battery posts, terminals and related accessories contain lead and lead compounds which are known to cause brain damage. Wash your hands after handling. ( P. 530)

Maintenance and care

WARNING
The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become electrically energize d. To avoid death or serious injury, observe the following precautions.
■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driving
as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel andbattery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and corro-
sive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage painted sur- faces. If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately. If you still experience discomfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is off. With the engine switch in IGNITION ON mode, the electric cooling fans may auto-matically start to run if the air conditioning is on and/or the coolant temperature is high.
( P. 529)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting in
your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■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 or when the fluid level in the accumulator is high.
If the reservoir needs frequent refillin g, it may indicate a serious problem.

The coolant level is satisfactory if it is between the “FULL” and “LOW” lines on
the reservoir when the engine is cold.
■Intercooler coolant reservoir (RC200t only)
The coolant level is satisfactory if it is between the “F” and “L” lines on the res-
ervoir when the engine is cold.

■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 hybridorganic 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 and intercooler coolant reservoir caps, drain
cock and water pump. If you cannot find a leak, have any authorized Lexus dealer or repairer, or another dulyqualified and equipped professional, test the cap and check for leaks in the cooling sys-
tem.
WARNING
■When the engine is hot (RC200t)
Do not remove the engine coolant reservoir cap, intercooler coolant reservoir cap and radiator cap. ( P. 662)
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. 662) The cooling system may be under pressure and may spray hot coolant if the cap isremoved, causing serious injuries, such as burns.
