■Registering air conditioning settings to elec tronic keys (vehicles with driving position
memory)
●Unlocking the vehicle using an electronic ke y and turning the engine switch to IGNI-
TION ON mode will recall that key's registered air conditioning settings.
●When the engine switch is tu rned off, the current air conditioning settings will automat-
ically be registered to the electronic ke y that was used to unlock the vehicle.
●The system may not operate correctly if more th an one electronic key is in the vicinity or
if the smart access system with push-button start is used to unlock a passenger door.
●The doors that can recall the air conditioning setting* when unlocked using the smart
access system with push-button start can be changed. For details, contact your Lexus
dealer.
*: The doors that can recall the driving posi tion memory are changed at the same time.
■Using automatic mode
Fan speed is adjusted automatically accordin g to the temperature setting and the ambi-
ent conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow immediately
after is pressed or “AUTO” is selected.
■Using the voice command system (veh icles with a navigation system)
Air conditioning system can be operated usin g voice commands. For details, refer to the

●The windows may fog up if the recirculated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recircu-
lated air mode button to the recirculated ai r mode. This is effective in preventing out-
side air from entering the vehicle interior. During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automati cally switch depending on the tempera-
ture setting or the inside temperature.
■When the outside temperature exceeds 75 F (24 C) and the air conditioning system
is on
●In order to reduce the air conditioning po wer consumption, the air conditioning system
may switch to recirculated air mode automa tically. This may also reduce fuel consump-
tion.
●Recirculated air mode is selected as a default mode when the engine switch is turned to
IGNITION ON mode.
●It is possible to switch to outside air mode at any time by pressing .
