■Registering air conditioning settings to electronic keys
●Unlocking the vehicle using an electronic key and turning the “START STOP
ENGINE” <“POWER”> switch to IGNITION ON mode will recall that key’s
registered air conditioning settings.
●When the “START STOP ENGINE” <“POWER”> is turned off, the current air con-
ditioning settings will automatically 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 access system with push-button start is used to unlock a passenger
door.
Settings for the electronic key and the corresponding door can be changed.
Contact your Lexus dealer.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the
ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow immedi-
ately after is pressed.
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Selecting
on will dehumidify the air from the outlets and defog the windshield effectively.
●If you turn off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Windshield fog detection function (if equipped)
When automatic mode is set, the humidity sensor ( →P. 377) detects fog on the
windshield and controls the air conditioning system to prevent fog.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/
recirculated air mode button to the recirculated air mode. This is effective in pre-
venting outside air from entering the vehicl e interior. During cooling operation, set-
ting the recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.

■When the outside temperature exceeds 75°F (24°C) and the air conditioning sys-
tem is on
●In order to reduce the air conditioning power consumption, the air conditioning
system may switch to recirculated air mode automatically. This may also reduce
fuel consumption.
●Recirculated air mode is selected as a default mode when the “START STOP
ENGINE” <“POWER”> switch is turned on.
●It is possible to switch to outside air mode at any time by pressing .
■Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and auto-
matically 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.
■Micro dust and pollen filter
●In order to prevent the windshield from fogging up when the outside air is cold, the
following may occur:
• Outside air mode does not switch to (recirculated air) mode.
• The dehumidification function operates.
• The operation cancels after approximately 1 minute.
●In rainy weather, the windows may fog up. Press .
●In extremely humid weather, the windows may fog up.
●The pollens are filtered out even if the micro dust and pollen filter is turned off.
■Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to priori-
tize fuel efficiency:
●Engine speed and compressor operation controlled 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
■When the outside temperature falls to nearly 32 °F (0 °C)
The dehumidification function may not operate even when is pressed.

■Humidity sensor (if equipped)
■To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is off.
In order to detect fog on the windshield, a
sensor which monitors the temperature of
the windshield, the surround humidity, etc. is
installed. ( →P. 3 74 )
Follow these points to avoid damaging the
sensor:
●Do not disassemble the sensor
●Do not spray the glass cleaner on the sen-
sor or subject it to strong impacts
