■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 se ats.
When a passenger is not detected in the front passenger seat,
depending on the set temperature and ambient temperature, prior -
ity 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.
The following S-FLOW modes are available:
Automatic S-FLOW mode
The system determines whether o r not a rear passenger is in the
vehicle by the opening and closing of a rear door. When a rear
passenger is determined to be in the vehicle, S-FLOW mode will
be automatically disabled.
To enable S-FLOW mode again, press and enter manual
S-FLOW mode. ( P. 507)
The indicator will illuminate when S-FLOW mode is
enabled.

may switch automatically.)
To defog the windshield and the side windows early, turn the ai r flow and
temperature up.
The indicator illuminates when the defoggers are on.
To return to the previous mode, press again when the wind-
shield is defogged. Also, turning the power switch off during o peration
can return to the previous mode.

■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 Air Conditioning System befor e driv-
ing ( P. 522). 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 approximately 14°F (-10°C) or low
• is operating
■ Using automatic mode
Fan speed is adjusted automatically according to the temperatur e 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.
