■Adjusting the position of and opening and closing the air outlets
Direct air flow to the left or right, up or down.
Turn the knob to open or close the vent.
■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 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.
●Settings for the electronic key and the corresponding door can be changed. Contact
any authorized Lexus retailer or Lexus author ized repairer, or any reliable repairer.
■Using automatic mode

■Outside/recirculated air mode
●When driving on dusty roads su ch 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 automatically 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 the 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 (P. 358)
■When the S-FLOW mode operates
If air flows to the driver’s seat only, the temperature setting for the front passenger’s seat
is not displayed.
■When the outside temperature is low
The dehumidification function may not operate even when “A/C” on the option control
screen is selected.
■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:

WARNING
■To prevent the windshield from fogging up
●Do not use during cool air operation in extremely humid weather. The d iffer-
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.
●Vehicles with windshield wiper de-icer: Do not touch the glass at lower part of the
windshield or to the side of the front pilla rs when the windshield wiper de-icer is on.
■nanoe generator (if equipped)
Do not disassemble or repair the generator because it contains high voltage parts.
Contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer 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
stopped.
■To prevent damage to the nanoe (if equipped)
Do not insert anything into the driver’s side vent, attach a nything 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 instrument
panel which may cover the air outlets. Other-
wise, air flow may be obstructed, preventing
the windshield defoggers from defogging.
