■ Setting the fan speed Operate the fan speed increase switch to increase the fan speed and the fan speed decrease switch to decrease the fan speed.

Press the off switch to turn the fan off.

■ Changing the air flow mode Press the airflow mode control switch.

The mode changes as follows each time the switch is pressed.

■ Switching between outside air and recirculated air modes Press the outside/recirculated air mode switch.

The mode changes as follows each time the switch is pressed.

(recirculated air mode) → automatic mode* → (outside air mode) → (recirculated air mode) When the system is switched to automatic mode, the air conditioning system operates automatically.

*: This item cannot be selected when the air conditioning is off.

■ Defogging the windshield Defoggers are used to defog the windshield and front side windows.

Press the windshield defogger switch.

Set the outside/recirculated air mode switch to outside air mode if the recirculated air mode is used. (It may switch automatically.) To defog the windshield and the side windows early, turn the air flow and temperature up.

To return to the previous mode, press the windshield defogger switch again when the windshield is defogged.

■ Defogging the rear window and outside rear view mirrors Defoggers are used to defog the rear window, and to remove raindrops, dew and frost from the outside rear view mirrors.

Press the rear window and outside rear view mirror defoggers switch.

The defoggers will automatically turn off after 15 minutes.

■When the outside temperature exceeds 75ºF (24ºC) 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 consumption.
• Recirculated air mode is selected as a default mode when the power switch is turned to ON mode.
• It is possible to switch to outside air mode at any time by pressing the outside/recirculated air mode switch.

■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.

■When driving on dusty roads Close all windows. If dust thrown up by the vehicle is still drawn into the vehicle after closing the windows, it is recommended that the air intake mode be set to outside air mode and the fan speed to any setting except off.

■Outside/recirculated air mode

• Setting to the recirculated air mode temporarily is recommended in preventing dirty air from entering the vehicle interior and helping to cool the vehicle when the outside air temperature is high.
• Outside/recirculated air mode may automatically switch regardless of the air conditioning setting depending on the temperature setting or inside temperature.

■Registering air conditioning settings to electronic keys

• Unlocking the vehicle using an electronic key and turning the power switch to ON mode will recall that key's registered air conditioning settings.

• When the power switch is turned off, the current air conditioning settings will automatically 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 the passenger door.

• Vehicles with the driving position memory: 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.

■Operation of the air conditioning system in Eco drive mode

In Eco drive mode, the air conditioning system is controlled as follows to prioritize fuel efficiency:

• Engine speed and compressor operation controlled to restrict heating/cooling capacity

• Fan speed restricted when automatic mode is selected

To improve air conditioning performance, perform the following operations:

• Turn off eco air conditioning mode

• Adjust the fan speed

• Turn off Eco drive mode

■When the outside temperature falls to nearly 32ºF (0ºC) The dehumidification function may not operate even when "A/C" is selected.

■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.

• When parking, the system automatically switches to fresh air intake mode to encourage better air circulation throughout the vehicle, helping to reduce odors that occur when starting the vehicle.

■Using the voice command system Air conditioning system can be operated using voice commands. For details, refer to the "NAVIGATION AND MULTIMEDIA SYSTEM OWNER'S MANUAL".

■Customization Settings (e.g. A/C Auto switch operation) can be changed.

WARNING

■To prevent the windshield from fogging up Do not use the windshield defogger switch during cool air operation in extremely humid weather. The difference 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.

WARNING

■When the outside rear view mirror defoggers are operating Do not touch the outside rear view mirror surfaces, as they can become very hot and burn you.

NOTICE

■To prevent 12-volt battery discharge Do not leave the air conditioning system on longer than necessary when the hybrid system is off.
