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 <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 vehicle 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.
