■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 your Lexus dealer.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and ambi-
ent conditions. As a result, the following may occur:
●The system may switch automatically to recirculated air mode when the coolest
temperature setting is selected when the ambient temperature is high.
●Immediately after the button is pressed, the fan may stop for a while until warm
or cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.

■Using the system in recirculated air mode
The windows will fog up more easily if recirculated air mode is used.
■Window defogger feature
Recirculated air mode may automatically switch to (outside air) mode in sit-
uations where the windows need to be defogged.
■When micro dust and pollen filter is active
●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 air conditioning system operates automatically.
• The operation cancels after 1 minute.
●In rainy weather, the windows may fog up. Press .
■When outside air temperature is below 32°F (0 °C)
The air conditioning function may not operate even when
is pressed.
■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into
and accumulate 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 conditio ning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.
CAUTION
■To prevent the windshield from fogging up
Do not use
during cool air operation in extremely humid weather. The dif-
ference 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.
