■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.

■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.

ture setting or the inside temperature.
■When the outside temperature is low
The dehumidification function may not operate even when “A/C” is selected.
■Operation of the air conditioning system in Eco drive mode
●In the Eco drive mode, the air conditioning system is controlled as follows to prioritize fuel efficiency
• Engine speed and compressor operation co ntrolled to restrict heating/cooling capacity• Fan speed restricted when automatic mode is selected
●To improve air conditioning performance, perform the following operations
• Adjust the fan speed
• Turn off Eco drive mode
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
●During use, various odors from inside and outside the vehicle may enter into and accu- mulate in the air conditioning system. This may then cause odor to be emitted from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode prior
to turning the vehicle off. • The start timing of the blower may be dela yed for a short period of time immediately after the air conditioning system is started in automatic mode.

■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.

WARNING
■To prevent the windshield from fogging up
●Do not use during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can cause the outer surface of the windshield to fog up, blocking your vision.
■To prevent burns
●Do not touch the rear view mirror surfaces when the outside rear view mirror defog-gers are on.
●Do not touch the glass at lower part of the windshield or to the side of the front pillarswhen the windshield wiper de-icer is on. (if equipped)
■nanoe  (if equipped)
Do not disassemble or repair the generator because it contains high voltage parts.
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional if the generator needs repair.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine is
off.
■To prevent damage to the nanoe (if equipped)
Do not insert anything into the driver’s side vent, attach anything to it, or use sprays
around the driver’s side vent. These things may cause the generator not to work prop- erly.
●Do not place anything on the instrumentpanel which may cover the air outlets. Other-
wise, air flow may be obstructed, preventing the windshield defoggers from defogging.
