Interior features
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. Unneces-
sary air conditioning is suppressed, contributing to increased fuel effi-
ciency.
Front seat concentrated airflow mode operates in the following situa-
tions.
●No passengers are detected in the rear seats
●The windshield defogger is not operating
While operating, illuminates.
■Manually turning front seat concentrated airflow mode on/off
In 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.
Press on the air conditioning operation panel and switch the
airflow.
●Indicator illuminated: Airflow to the front seats only
●Indicator off: Airflow to all the seats

Interior features
■ Heating
● In HV mode, the gasoline engine may operate in order to extract 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 on the outside heat exchanger, the heating perfor-
mance will decline. The frost can be removed from the outside heat
exchanger by operating the Remote Ai r Conditioning System before driv-
ing ( P. 585). When frosted over, the heating operation of the Remote
Air Conditioning System starts after defrosting.
• When is turned on, the heating is controlled optimally. Therefore,
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
extract heat from the engine coolant via the heater even in EV mode.
• The outside temperature is approx imately -10°C (14°F) or 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.
• 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.Outside heat exchanger

■Water droplets during air conditioning operation
■ Setting confirmation screen
■ Operation of automatic airflow control
● In order to maintain a comfortable interior, airflow may be directed to seats
without passengers immediately after the hybrid system is started and at
other times depending on the outside temperature.
● After the hybrid system 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 control
Even if the function is manually switched to directing airflow to only the
front seats, when a rear seat is occupied, it may automatically direct air-
flow to all seats.
■ To return to automatic airflow control
With the indicator off, turn the power switch off.
After 60 minutes or more elapse, turn the power switch to ON.
■ Front seat concentrated airflow mode (S-FLOW) operation
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.
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 pressed, the front seat
concentrated airflow mode (S-FLOW) sta-
tus is displayed on the multi-information
display.
