■ S-FLOW mode In S-FLOW mode, priority for the airflow is given to the front seats, reducing the airflow and air conditioning effect on the rear seats. When in S-FLOW mode, airflow from the rear air conditioning system is stopped. (RX450hL) Operation in S-FLOW mode differs according to the following conditions:

  • Priority is given to the driver's seat only when: Manual S-FLOW mode: When no passenger is judged to be in the front passenger seat.

Automatic S-FLOW mode: When no passengers are judged to be in the front passenger seat or rear seats.

  • Priority is given to the front seats when: Manual S-FLOW mode is selected or no passengers are judged to be in the rear seats when in automatic SFLOW mode.

  • S-FLOW mode will be disabled when: A passenger is judged to be in a rear seat when in automatic S-FLOW mode.

Depending on the set temperature, operation in S-FLOW mode may not change as described above.

When certain conditions are met and priority is given to the driver's seat only, the temperature indicator for the front passenger side will turn off.

  2. Turn the knob to open or close the vent

■ 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 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 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.

■ How the system judges if a passenger is in the vehicle when in S-FLOW mode In S-FLOW mode, the system judges if a passenger is in the vehicle as follows:

  • Front passenger seat: A passenger is judged to be in the front passenger seat when the system detects an object on the front passenger seat, fastening of the front passenger seat belt, changing of the set temperature for the front passenger seat or the opening and closing of the front passenger door. (However, when only opening and closing of the front passenger door is detected, the system will judge that a passenger is not in the front passenger seat after the vehicle speed reaches approximately 12 mph (20 km/h) or more.)
  • Rear seats (automatic S-FLOW mode only): A passenger is judged to be in a rear seat when the system detects the opening and closing of a rear door or the operation of the rear air conditioning system (RX450hL).

If a passenger is judged to be in the vehicle, the system will retain the judgement for a certain amount of time after the power switch is turned off.

■ Operation of automatic S-FLOW mode When the system is operating in automatic S-FLOW mode, if the system detects the opening and closing of a rear door or the operation of the rear air conditioning system (RX450hL), S-FLOW mode will be disabled. To enable S-FLOW mode, select on the option control screen. (In this case, the system will operate in manual S-FLOW mode.)

■ Changing from manual S-FLOW mode to automatic S-FLOW mode

1. Select on the option control screen to disable S-FLOW mode.

2. Turn the power switch off.

3. Wait for 60 minutes or more and change the power switch to ON mode.

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

■ 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 button.

■ Automatic mode for air intake control 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.

■ Fogging up of the windows

  • The windows will easily fog up when the humidity in the vehicle is high. 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.

■ Windshield fog detection function

When automatic mode is set, the humidity sensor detects fog on the windshield and controls the air conditioning system to prevent fog.

■ Outside/recirculated air mode

  • When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recirculated air mode button to the recirculated air mode. This is effective in preventing outside 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 temperature setting or the inside temperature.

■ When the outside temperature is low The dehumidification function may not operate even when "A/C" is selected.

■ Operation of the air conditioning system in Eco drive mode

  • In the 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:

    • Adjust the fan speed

    • Turn off Eco drive mode

■ 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.

  • 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.

■ Customization Some functions can be customized

WARNING

■ To prevent the windshield from fogging up

  • Do not use 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.

  • Do not place anything on the instrument panel which may cover the air outlets. Otherwise, air flow may be obstructed, preventing the windshield defoggers from defogging.

Lexus RX. Using the air conditioning system and defogger

■ To prevent burns

  • Do not touch the rear view mirror surfaces when the outside rear view mirror defoggers are on.
  • 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. (if equipped)

NOTICE

■ Humidity sensor

In order to detect fog on the windshield, a sensor which monitors the temperature of the windshield, the surround 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

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