Automatic air conditioning system

Air outlets and fan speed are automatically adjusted according to the temperature setting.
Press the “MENU” button on the Remote Touch, then select to display the air conditioning control screen.
The air conditioning system can be displayed and operated on the side display.

Air conditioning controls

• A Left-hand side temperature control switch
  B Fan speed control switch
  C Airflow mode control switch
  D Right-hand side temperature control switch
  E Automatic mode switch
  F Off switch
  G Front windshield defogger switch
  H Rear windshield and outside rearview mirror defogger switch
• I Outside/recirculated air mode switch
• J A/C switch
  K DUAL switch

Adjusting the temperature setting
Operate the temperature control switch upwards to increase the temperature and downwards to decrease the temperature.
If “A/C” switch is not pressed, the sys-tem will blow ambient temperature air or heated air.

Adjusting the fan speed setting
Operate the fan speed control switch upwards to increase the fan speed and downwards to decrease the fan speed. Press the off switch to turn the fan off.

Change the airflow mode
Operate the airflow mode control switch upwards or downwards.
The mode changes as follows each time the switch is operated.

• A Air flows to the upper body.
• B Air flows to the upper body and feet.
  C Air flows to the feet.
  D Air flows to the feet and the windshield defogger operates.

Switching between outside air and recirculated air modes 
Press the outside/recirculated air mode switch.
The mode switches between outside air mode (the indicator is off) and recirculated air mode (the indicator is on) each time the button is pressed.

Defogging the windshield 
Defoggers are used to defog the wind shield and front side windows.
Press the front windshield defogger switch.
Set the outside/recirculated air mode switch to outside air mode if the recirculated air mode is used. (It may switch auto-matically.)
To defog the windshield and the side win-dows early, turn the air flow and temperature up.
To return to the previous mode, press the front windshield defogger switch again when the windshield is defogged.

Defog 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 rearview mirrors.
Press the rear windshield and outside rear view mirror defogger switch.
The defoggers will automatically turn off after a period of time.

• 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 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. Pressing “A/C” button or selecting “A/C” 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 auto-matically 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 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 auto-matically 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, con-tact 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 mode 
  • In the Eco mode, the air conditioning sys-tem 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
    Adjust the fan speed
    Adjust the temperature setting
    Turn off Eco mode
  • Even when the driving mode is set to Eco mode, the air conditioning eco mode can be turned off by selecting the ECO HEAT/COOL
• When the outside temperature is low
  The dehumidification function may not operate even when “A/C” is pressed or “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 sys-tem. 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.
• Air conditioning filter P.367
• Customization 
  Settings (e.g. A/C automatic mode switch operation) can be changed. (Customizable features: P. 441)

WARNING

• To prevent the windshield from fogging up
  Do not use the front 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.
• To prevent burns
• Do not touch the rear view mirror sur-faces when the outside rearview mir-ror defoggers are on.
• Vehicles with windshield wiper de-icer: Do not touch the glass at lower part of the windshield or to the side of the front pillars when the windshield wiper de-icer is on.

Using automatic mode

1. Press the “AUTO” button.
2. Adjust the temperature setting.
3. To stop the operation, press the
   “OFF” button.

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.

• Using automatic mode
  Fan speed is adjusted automatically accord-ing 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 “AUTO” button is pressed or “AUTO” is selected.
• Windshield fog detection function
  When automatic mode is set, the humidity
  sensor (P.295) detects fog on the wind shield and controls the air conditioning sys-tem to prevent fog.
• Air conditioning filter P.367
• Customization
• Settings (e.g. A/C automatic mode switch operation) can be changed. (Customizable features: P.441)

NOTICE
Humidity sensor
In order to detect fog on the windshield, a sensor that monitors the temperature of the windshield, the surrounding humidity, etc., is installed.
Follow these points to avoid damaging the sensor:

• Do not disassemble the sensor
• Do not spray the glass cleaner on the sensor or subject it to strong impacts
• Do not stick anything on the sensor
