Air conditioning system settings

When the "POWER" switch is turned on, the air conditioning system
settings will be set to those that were in use the last time the "POWER"
switch was turned off.

Air conditioning system settings are memorized individually on each
electronic key, so the settings reproduced will be specific to the key that
is used.

This feature is customizable at any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.

Using automatic mode

ambient conditions. As a result, the following may occur:
Immediately after the button is pressed, the fan may stop for a while until
warm or cool air is ready to flow.

Using the system in recirculated air mode
The windows will fog up more easily if recirculated air mode is used for an
extended period.

Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched in
accordance with the temperature setting and the inside temperature.
