■Registering air conditioning settings to electronic keys (vehicles with driving position
memory)
●Unlocking the vehicle using an electronic ke y and turning the engine switch to IGNI- TION ON mode will recall that key’s registered 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 conditioni ng 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 the “AUTO” button is pressed or “AUTO” is selected.
■Operation of S-FLOW mode
In automatic mode, S-FLOW mode will be turned off if a rear door has been opened and
closed. To activate S-FLOW mode again, press .
■Automatic mode for air intake control (if equipped)
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.
■Fogging up of the windows
●The windows will easily fog up when the humidi ty in the vehicle is high. Selecting “A/C” will dehumidify the air from the outlets 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.

■nanoe (if equipped)
Your vehicle incorporates a nanoe device, which is considered a biocidal product.
The nanoe  device generates charged water particles from the ambient air. These parti-
cles purify the air in the cabin by suppressing bacteria.
The nanoe  device is considered a biocidal product in the EU according to the interpre- tation of Regulation (EU) No 528/2012.
Active substances: Charged water particles (nano) containing hydroxyl radicals, gener- ated from ambient air
nanoe  helps to provide purified air by emitting electrically charged water particles
through the window side air outlet of the driver's seat*.
●When the fan is turned on and “nanoe” on the option control screen is selected, the nanoe  is activated.
●When the fan is operated in the following conditions, system performance will be maxi- mized. If the following conditions are not met, the nanoe  may not operate at full capacity.
• The upper body, the upper body and feet or the feet air outlets are being used. ( P. 538) • The window side air outlet of the driver’s seat is open.
●When nanoe  is generated, a small amount of ozone is emitted and may be faintly smelled in some situations. However, this is approximately the same as the amount that
already exists in nature, such as in forests, and it has no affect on the human body.
●A slight noise may be heard during operation. This is not a malfunction.
*: According to temperature and humidity conditions, fan speed and direction of the air
flow, the nanoe  may not operate at full capacity.
