RC200t (vehicles without Adaptive Variable Suspension System)
Normal mode
Provides an optimal balance of fuel ec onomy, quietness, and dynamic perfor-
mance. Suitable for city driving.
Press the switch to change the driving mode to normal mode when Eco drive mode or sport mode is selected.
Eco drive mode
Helps the driver accelerate in an eco-friendly manner and improve fuel econ-
omy through moderate throttle characteristics and by controlling the opera-
tion of the air conditioning system (heating/cooling).

■Registering air conditioning settings to electronic keys
●Unlocking the vehicle using an electronic ke y and turning the engine switch to IGNI-
TION ON mode will recall that key's re gistered air conditioning settings.
●When the engine switch is turned off, the current air conditioning settings will automat-
ically be registered to the electronic key that was used to unlock the vehicle.
●The system may not operate correctly if more than one electronic key is in the vicinity or
if the smart entry & start system is used to unlock a passenger door.
●The doors that can recall the air conditioning setting* when unlocked using the smart
entry & start system can be changed. For details, contact any authorized Lexus dealer
or repairer, or another duly qu alified and equipped professional.
*: The doors that can recall the driving position memory are changed at the same time.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the ambi-
ent conditions.
Therefore, the fan may stop for a while until wa rm or cool air is ready to flow immediately
after is pressed or “AUTO” is selected.
■Fogging up of the windows
The windows will easily fog up when the hu midity in the vehicle is high. Turning
(“A/C”) on will dehumidify the air from the ou tlets and defog the windshield effectively.
●If you turn (“A/C”) off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recircu-
lated air mode button to the recirculated air mode. This is effective in preventing out-
side air from entering the vehicle interior . During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automati cally switch depending on the tempera-
ture setting or the inside temperature.
■Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and automati-
cally switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function.
■Operation of the air conditioning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to prioritize fuel
efficiency:
●Engine speed and compressor operation controlled to restrict heating/cooling capac-
ity
●Fan speed restricted when automatic mode is selected
To improve air conditioning performanc e, perform the following operations:
●Adjust the fan speed
●Turn off Eco drive mode

Maintenance and care
RC200t_RC F_EE(OM24728E)
■Automatic car washes (vehicles with CFRP parts)
Do not use automatic car washes as they may scratch the CFRP parts and damage the paint.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the windows.
●Before using the car wash, check that the fuel filler door on your vehicle is closed prop-
erly.
■When using a car wash
If the door handle becomes wet while the electronic key is within the effective range, the
door may lock and unlock repeatedly. In that case, follow the following correction proce- dures to wash the vehicle:
●Place the key in a position 2 m (6 ft.) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
●Set the electronic key to battery-saving mode to disable the smart entry & start system. ( P. 177)
■Aluminum wheels
●Remove any dirt immediately by using a neutral detergent. Do not use hard brushes or abrasive cleaners. Do not use strong or harsh chemical cleaners.
Use the same mild detergent and wax as used on the paint.
●Do not use detergent on the wheels when they are hot, for example after driving a long distance in hot weather.
●Wash detergent from the wheels immediately after use.
■When cleaning the painted brake calipers (if equipped)
●If a detergent is to be used to clean the painted brake calipers, use a neutral detergent.
Do not use hard brushes or abrasive cl eaners as they may damage the paint.
●Do not use detergent on the brake calipers when they are hot.
●Wash detergent from the brake calipers immediately after use.
■Bumpers
Do not scrub with abrasive cleaners.
■Side windows water-repellent coating
●The following precautions can extend the effectiveness of the water-repellent coating.
• Remove any dirt, etc. from the side windows regularly.
• Do not allow dirt and dust to accumulate on the windows for a long period. Clean the windows with a soft, damp cloth as soon as possible.• Do not use wax or glass cleaners that co ntain abrasives when cleaning the windows.
• Do not use any metallic objects to remove condensation build up.
●When the water-repellent performance has become insufficient, the coating can be
repaired. Contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.

Maintenance and care
RC200t_RC F_EE(OM24728E)
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.

■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drivetrain
If a tire needs frequent inflating, have it checked by any authorized Lexus dealer or repairer, or another duly qua lified and equipped professional.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold. If your vehicle has been parked for at least 3 hours or has not been driven for more than
1.5 km or 1 mile, you will get an accurate cold tire inflation pressure reading.
●Always use a tire pressure gauge. It is difficult to judge if a tire is prop erly inflated based only on its appearance.
●It is normal for the tire inflation pressure to be higher after driving as heat is generated in the tire. Do not reduce tire inflation pressure after driving.
●Passengers and luggage weight should be placed so that the vehicle is balanced.
Tire inflation pressure
Make sure to maintain proper tire infl ation pressure. Tire inflation pressure
should be checked at least once per month. However, Lexus recommends
that tire inflation pressure be checked once every two weeks. ( P. 679)
