PRIUS_OM_OM47D44U_(U)■
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 or not a rear passenger is in the
vehicle by the opening and closing of a rear door. When a rear pas-
senger is determined to be in t he vehicle, S-FLOW mode will be
automatically disabled.
To enable S-FLOW mode again, select and enter manual S-
FLOW mode. ( P. 440)
The indicator will illuminate when S-FLOW mode is enabled.
Manual S-FLOW mode
When is selected, S-FLOW mo de will be manually enabled/
disabled. ( P. 440)
The indicator will illuminate when S-FLOW mode is enabled.
When the power switch is turned to ON mode, the system is oper-
ated in automatic S-FLOW mode.
