Interior features
a front passenger is in the vehicle by
the opening and closing of the front
passenger’s door.
When a front passenger is determined
not to be in the vehicle, the tempera-
ture indicator and air flow indicator for
the front passenger side will turn off. In
this case, depending on the set tem-
perature and ambient temperature,
priority for the airflow will be given to
the driver’s seat only.
The following S-FLOW modes are
available:
Automatic S-FLOW mode
In this mode, the system determines
whether or 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.
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.
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.
■ Operation of the air conditioning sys-
tem in S-FLOW mode
If the front passenger’s door or a rear door
is opened then closed, the air conditioning
system determines that a passenger is in the
vehicle. In this case, priority for the airflow
will be changed from the driver’s seat only
to the front seats only or all seats, respec-
tively.
(Depending on the set temperature or
ambient temperature, priority for the air-
flow may not be given to the driver’s seat
only.)
If a passenger is judged to be in the vehicle,
the system will retain the judgement for a
certain amount of time after the power
switch is turned off.
■ Operation of automatic S-FLOW mode
When the system is operating in automatic
S-FLOW mode, if a rear door is opened
and then closed, S-FLOW mode will be dis-
abled. To enable S-FLOW mode, select the
S-FLOW mode switch.
■ Changing from manual S-FLOW mode
to automatic S-FLOW mode
1 Select the S-FLOW mode switch to dis-
able S-FLOW mode.
2 Turn the power switch off.
3 After 60 minutes have elapsed, change
the power switch to ON mode.
