■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.

Rotate the tires in the order shown.
To equalize tire wear and help extend tire life, Lexus recommends that tire rotation is
carried out approximately every 10000 km (6000 miles).
Do not fail to initialize the tire pressure warning system after tire rotation.

Maintenance and care
RC200t_RC F_EE(OM24728E)
Your vehicle is equipped with a tire pressure warning system that uses tire pres-
sure warning valves and transmitters to detect low tire inflation pressure before
serious problems arise.
Vehicles without the tire inflation pressure display function
If the tire pressure drops below a predetermined level, the driver is warned by a
warning light. ( P. 593)
Vehicles with the tire inflation pressure display function
●If the tire pressure drops below a predetermined level, the driver is warned by
a screen display and a warning light. ( P. 593, 609)
●The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. ( P. 131, 139)
The illustration used is intended as an example, and may differ from the image
that is actually displayed on the multi- information display.
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and transmitters
must also be installed.
When new tire pressure warning valves and transmitters are installed, new ID
codes must be registered in the tire pressure warning computer and the tire
pressure warning system must be initialized. Have tire pressure warning valve
and transmitter ID codes registered by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional. ( P. 538)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the following circum-
stances:
●When rotating the tires.
●When the tire inflation pressure is changed such as when changing
traveling speed.
●When changing the tire size.
When the tire pressure warning system is initialized, the current tire inflation
pressure is set as the benchmark pressure.

■How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch off.
Initialization cannot be perfor med while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation pressure
level. ( P. 679)
Make sure to adjust the tire pressure to the specified cold tire inflation pressure level. The tire pressure warning system will operate based on this pressure level.
Turn the engine switch to IGNITION ON mode.
Press and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly 3 times.
Wait for a few minutes with the engine switch in IGNITION ON mode and
then turn the engine switch off.
◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a unique ID
code. When replacing a tire pressure wa rning valve and transmitter, it is nec-
essary to register the ID code. Have the ID code registered by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.

■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose the fabric, and
bulges indicating internal damage
●A tire goes flat repeatedly or cannot be prop erly repaired due to the size or location of a cut or other damage
If you are not sure, consult any authorized Lexus dealer or repairer, or another duly qual- ified and equipped professional.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered, the tire pressure warning system will not work proper ly. After driving for about 10 minutes, the tire pressure warning light blinks for 1 minu te and stays on to indicate a system malfunc-
tion.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has seldom
or never been used or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system does not re place routine tire inflation pressure checks.
Make sure to check tire inflation pressure as part of your routine of daily vehicle checks.
■When rotating the tires (vehicles with the tire pressure warning system featuring a tire inflation pressure display function)
Make sure that the engine switch is off. If the tires are rotated while the engine switch is in IGNITION ON mode, the tire position information will not be updated.If this accidentally occurs, either turn the en gine switch to off and then to IGNITION ON
mode, or initialize the system after checking th at the tire pressure is properly adjusted.
■Low profile tires (except 17-inch tires)
Generally, low profile tires will wear more ra pidly and tire grip performance will be
reduced on snowy and/or icy roads when comp ared to standard tires. Be sure to use snow tires or tire chains on snowy and/or icy roads and drive carefully at a speed appro- priate for road and weather conditions.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
