NOTICE
Humidity sensor
■
In order to detect fog on the windshield,
a sensor which monitors the temperature
of the windshield, the surround humidity,
etc. is installed.
Follow these points to avoid damaging
the sensor:
● Do not disassemble the sensor
● Do not spray the glass cleaner on the
sensor or subject it to strong impacts
Do not stick anything on the sensor
●
S-FLOW mode (if equipped)
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 (P.357), S-
FLOW mode will be automatically dis-
abled.
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.
When the rear seat temperature con-
trol switch is operated, S-FLOW mode
will be disabled. (vehicles with "3-
ZONE" mode)
The system does not determine
whether a passenger is in the rear seats
by the opening 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. (P.357)

FLOW mode
