(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 MIRRORSDefoggers 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 a period of time.WINDSHIELD WIPER DE-ICER (IF EQUIPPED)Windshield wiper de-icer (if equipped)Note:When the outside temperature exceeds 75°F (24°C) and the air conditioning system is onIn 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 engine switch is turned to IGNITION 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 windowsThe windows will easily fog up when the humidity in the vehicle is high. Selecting “ 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 roadsClose 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 modeSetting 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 depending on the temperature setting or the inside temperature.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 IGNITION ON mode will recall that key’s registered air conditioning settings.When the engine 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 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.Operation of the air conditioning system in Eco drive modeIn 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 capacityFan speed restricted when automatic mode is selectedTo improve air conditioning performance, perform the following operations:Adjust the fan speedTurn off Eco drive mode (Driving mode select switch)When the outside temperature falls to nearly 32°F (0°C)The dehumidification function may not operate even when “ A/C” is selected.Ventilation and air conditioning odorsTo 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.Using the voice command systemAir conditioning system can be operated using voice commands. For details, refer to “ NAVIGATION AND MULTIMEDIA SYSTEM OWNER’S MANUAL”.Air conditioning filterAir conditioning filterAir conditioning system refrigerantA label regarding the refrigerant of the air conditioning system is attached to the hood at the location shown in the following illustration.

The meaning of each symbol on the label are as follows:

CustomizationSome functions can be customized. (Customizable features)WARNING:To prevent the windshield from fogging upDo 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.When the outside rear view mirror defoggers are operatingDo not touch the outside rear view mirror surfaces, as they can become very hot and burn you.NOTICE:To prevent battery dischargeDo not leave the air conditioning system on longer than necessary when the engine is off.When repairing/replacing parts of the air conditioning systemHave repair/replacement performed by your Lexus dealer.When a part of the air conditioning system, such as the evaporator, is to be replaced, it must be replaced with a new one.AIR CONDITIONING CONTROL SCREENMain control screenUsing the touchpad of the Remote Touch, select the button on the screen.This system can also be operated by the touch screen.Vehicles with DUAL-ZONE climate control

(Air conditioning control screen)Press the outside/recirculated air mode switch to switch to automatic air intake mode. (if equipped)The air conditioning system automatically switches between outside air and recirculated air modes.Adjust the temperature setting.To stop the operation, press the off switch or select “ OFF” on the sub function menu. (Air conditioning control screen)If the fan speed setting or air flow modes are operated, the automatic mode indicator goes off. However, automatic mode for functions other than that operated is maintained.Note:Using automatic modeFan speed is adjusted automatically according to the temperature setting and the ambient conditions.Therefore, the fan may stop for a while until warm or cool air is ready to flow immediately after the automatic mode switch is pressed or “ AUTO” is selected.Cool air may blow around the upper body even when the heater is on due to sunlight.Automatic mode for air intake control (if equipped)In automatic mode, the system detects exhaust gas and other pollutants and automatically switches between outside air and recirculated air modes.When the dehumidification function is off, and the fan is operating, turning automatic mode on will activate the dehumidification function.FRONT SEAT CONCENTRATED AIRFLOW MODE (S-FLOW)This function automatically controls the air conditioning airflow so that priority is given to the front seats. When the front passenger seat is not occupied, airflow may switch to only the driver's seat. Unnecessary air conditioning is suppressed, contributing to increased fuel efficiency.Front seat concentrated airflow mode operates in the following situations.No passengers are detected in the rear seatsThe windshield defogger is not operatingWhile operating,  illuminates.MANUALLY TURNING FRONT SEAT CONCENTRATED AIRFLOW MODE ON/OFFIn front seat concentrated airflow mode, directing airflow to the front seats only and to all seats can be switched via switch operation. When the mode has been switched manually, automatic airflow control stops operating.Select  on the center display and switch the airflow.Indicator illuminated: Airflow to the front seats onlyIndicator off: Airflow to all the seatsNote:Operation of automatic airflow controlIn order to maintain a comfortable interior, airflow may be directed to seats without passengers immediately after the engine is started and at other times depending on the outside temperature.After the engine is started, if passengers move around inside or enter/exit the vehicle, the system cannot accurately detect the presence of passengers and automatic airflow control will not operate.Operation of manual airflow controlEven if the function is manually switched to directing airflow to only the front seats, when a rear seat is occupied, it may automatically direct airflow to all seats.To return to automatic airflow controlWith the indicator off, turn the engine switch off.After 60 minutes or more elapse, turn the engine switch to ON.ADJUSTING THE TEMPERATURE FOR THE DRIVER AND PASSENGER SEATS SEPARATELYVehicles with DUAL-ZONE climate controlTo turn on the “ DUAL” mode, perform any of the following procedures:Select “ DUAL” on the sub function menu.
