■Air conditioning system settings
●When the “ENGINE START STOP” switch is turned on, the air conditioning
system settings will be set to those that were in use the last time the “ENGINE
START STOP” 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
Fan speed is adjusted automatically according to the temperature setting and ambi-
ent 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 accor-
dance with the temperature setting and the inside temperature.
■Window defogger feature

■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 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 conditioning 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.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine
is off.
