6-1. Using the air conditioning system
■ Registering air conditioning settings to electronic keys (vehicles with driving position
memory)
● Unlocking the vehicle using an electronic key and turning the engine switch to IGNI-
TION ON mode will recall that key's registered air conditioning settings.
● When the engine switch is turned off, the current air conditioning settings will automat-
ically 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.
● 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 position memory are changed at the same time.
■ Using automatic mode
Fan speed is adjusted automatically according 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 (vehicles with a navigation system)
Air conditioning system can be operated using voice commands. For details, refer to the
“NAVIGATION SYSTEM OWNER’S MANUAL”.
■ Fogging up of the windows
The windows will easily fog up when the humidity in the vehicle is high. Turning
(“A/C”) on will dehumidify the air from the outlets and defog the windshield effectively.
● If you turn (“A/C”) off, the windows may fog up more easily.
● 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 air 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 automatically 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 power consumption, the air conditioning system
may switch to recirculated air mode automatically. 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 .
