WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do so may result in death or serious injury.
●After exiting the vehicle and before opening the fuel door, touch an unpainted metalsurface to discharge any static electricity. It is important to discharge static electricity before refueling because sparks resulting fr om static electricity can cause fuel vapors
to ignite while refueling.
●Always hold the grips on the fuel tank cap and turn it slowly to remove it. A whooshing sound may be heard when the fuel tank cap is loosened. Wait until the
sound cannot be heard before fully removing the cap. In hot weather, pressurized fuel may spray out the filler neck and cause injury.
●Do not allow anyone that has not discharged static electricity from their body to come
close to an open fuel tank.
●Do not inhale vaporized fuel. Fuel contains substances that are harmful if inhaled.
●Do not smoke while refueling the vehicle.Doing so may cause the fuel to ignite and cause a fire.
●Do not return to the vehicle or touch any person or object that is statically charged.
This may cause static electricity to build up, resulting in a possible ignition hazard.
■When refueling
Observe the following precautions to prevent fuel overflowing from the fuel tank:
●Securely insert the fuel nozzle into the fuel filler neck.
●Stop filling the tank after the fuel nozzle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling. Doing so may damage the vehicle, such as causing the emission control system tooperate abnormally or damaging fuel system components or the vehicle’s painted sur-
face.

Interior features
RC300h_EE(OM24740E)
■Registering air conditioning settings to electronic keys (vehicles with driving position
memory)
●Unlocking the vehicle using an electronic key and turning the power switch to ON
mode will recall that key's registered air conditioning settings.
●When the power switch is turned off, the cu rrent air conditioning settings will automati-
cally 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
