2825-3. Using the air conditioning system and defogger
In S-FLOW mode, priority for the air-
flow 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 con-
ditioning 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 ( P.280).
Manual S-FLOW mode
When the S-FLOW mode switch is
selected, S-FLOW mode will be manu-
ally enabled/disabled.
The indicator will illuminate on the air con-
ditioning control screen when S-FLOW
mode is enabled.
The system does not determine whether a
passenger is in the rear seats by the open-
ing and closing of a rear door, so S-FLOW mode cannot be automatically disabled.
To automatically disable S-FLOW mode by
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 tem-
perature and air conditioning load is
high, the operation may not change.
 Driver seat priority:
• When the system determines there is no
passenger in the front passenger seat in
manual S-FLOW mode
• When the system determines there are no passengers in the front passenger
seat and rear seats in automatic S-
FLOW mode
The airflow to the front passenger seat and
rear seat stops and the front passenger
temperature display turns off.
 Front seat priority:
When the system determines there are no
passengers in the rear seats
S-FLOW disabled:
When the system determines there is a
passenger in the rear seats
■Passenger presence determination in S-
FLOW mode
The system determines that there is a pas-
senger 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.
