S-FLOW mode
In S-FLOW mode, priority for the ai
rflow is given to the front seats,
reducing the airflow and air conditio ning effect on the rear seats.
If a passenger is not detected in the front passenger seat, priority
for the airflow will be given to the driver’s seat only.
However, air will always be blown from the side outlet of the front pas-
senger seat.
S-FLOW mode will be activated autom atically according to the set
temperature, outside temperature, etc. ( →P. 505)
The S-FLOW mode can be turned on/off manually by selecting on
the air conditioning control screen.
The indicator illuminates when in S-FLOW mode.

dows.
Press .
Set 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.

■Heating
●In HV mode, the gasoline engine may operate in order to exhaust heat from
the engine coolant via the heater.
● In EV mode, heating is done by a heat pump system.
• When the outside temperature is low or it is snowing, compared to con-
ventional vehicles, heating may be less effective and warm air may not
come out.
• If frost has formed of the outside heat exchanger, the heating perfor- mance will decline. The frost can be removed from the outside heat
exchanger by operating the Remote Air Conditioning System before driv-
ing ( →P. 509). When frosted over, the heating operation of the Remote
Air Conditioning System starts after defrosting.
• When is turned on, the heating is controlled optimally. There- fore, the set heating performance may not be achieved even if the fan
speed setting is increased.
● In the following situations the gasoline engine may operate in order to
exhaust heat from the engine coolant via the heater even in EV mode.
• The outside temperature is extremely low
• is operating
■ 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 is pressed.
■ Water droplets during air conditioning operation• When the outside heat exchanger is
frosted over, fan speed declines and it
may become harder to heat the inte-
rior. However, it is not a malfunction.
In this situation, the air temperature
from the outlets may not change even
though the set temperature is raised.
The outside heat exchanger, accumulator
and air conditioning piping may incur con-
densation or frost may form. During or
after the air conditioning operation, water
droplets may fall from the vehicle. How-
ever, it is not a malfunction.

■Setting confirmation screen
■ S-FLOW mode operation
●In automatic mode, S-FLOW mode will be turned off if a rear door has been
opened and closed. To activate S-FLOW mode again, select .
■ Changing settings using the multi-information display
The air conditioning system settings can be changed on the screen of
the multi-information display. ( →P. 226)
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
● If you turn 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 ( →P. 508) 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
to the recirculated air mode. This is effective in preventing out-
side 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 changing the settings of the air
conditioning system, the setting confirma-
tion screen is shown as a pop-up on the
multi-information display.
Press of the meter control switches to
go back to the previous screen.
●
When is selected, the S-FLOW
mode status is displayed on the multi-
information display.

Fresh air intake system while parking
When parking, the system automatically switches to outside air mode to
encourage better air circulation throughout the vehicle, helping to reduce
odors that occur when starting the vehicle.
■ Operation of the air conditioning system in the air conditioning eco
mode
●In the air conditioning eco 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
• Adjust the temperature setting
• Turn off the air conditioning eco mode
● When the driving mode is set to Eco driving mode, the air conditioning eco
mode will be turned on automatically. Even in this case, the air conditioning
eco mode can be turned off by selecting . ( →P. 406)
■ When the outside temperat ure falls to nearly 32°F (0°C)
The dehumidification function may not operate even when is
selected.
■ Ventilation and air conditioning odors
●To let the 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.
● In order to suppress odors that occur when the air conditioning system
starts, fresh air is automatically taken in when parked.
● To reduce potential odors from occurring, the start timing of the blower may
be delayed for a short period of time i mmediately after the air conditioning
system is started in automatic mode.
