(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

■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.

■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

■Registering air conditioning settings to electronic keys

*: 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:

To improve air conditioning performance, perform the following operations:

■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

■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.

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 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.

■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.

■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. The next time the dehumidification function is turned off, the AUTO mode for switching between outside air and recirculated air modes is canceled.

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:

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.

The following S-FLOW modes are available:

Automatic S-FLOW mode

When a rear passenger is determined to be in the vehicle, S-FLOW mode will be automatically disabled.

The indicator will illuminate on the air conditioning control screen when S-FLOW mode is enabled.

To enable/disable S-FLOW mode and enter manual S-FLOW mode, select the S-FLOW mode switch.

Manual S-FLOW mode

When the S-FLOW mode switch is selected, S-FLOW mode will be manually enabled/disabled.

The indicator will illuminate on the air conditioning control screen when S-FLOW mode is enabled.

In this mode, the system does not determine whether a passenger is in the rear seats, so S-FLOW mode cannot be automatically disabled.

To automatically disable S-FLOW mode when opening and closing a rear door, switch to automatic S-FLOW mode.

■ S-FLOW air conditioning control Operation of S-FLOW mode changes according to the following conditions.

However, depending on the set temperature, the operation may not change.

The front passenger temperature display turns off.

■Passenger presence determination in SFLOW mode

The system determines that there is a passenger in any of the following situations.

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

Front passenger seat

After only the front passenger side door is opened and closed, when the vehicle is driven at 12 mph (20 km/h) or more, the system determines that there is no passenger in the front passenger seat.

Rear seats

When a rear door is opened and closed

■Operation of automatic S-FLOW mode When the system is operating in S-FLOW mode, if a rear door is opened and then closed, S-FLOW mode will be disabled. To enable S-FLOW mode, select the S-FLOW mode switch. In this case, the system switches to manual S-FLOW mode.

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

1. Select the S-FLOW mode switch to disable S-FLOW mode.

2. Turn the power switch off.

3. After 60 minutes have elapsed, change the power switch to ON mode.
