warm or cool air is ready to flow immedi-
ately after the automatic mode switch is
pressed or "AUTO" is selected.
Cool air may blow around the upper body
even when the heater is on due to sunlight.

In automatic mode, the system detects
exhaust gas and other pollutants and auto-
matically switches between outside air and
recirculated air modes.
When the dehumidification function is off,
and the fan is operating, turning automatic
mode on will activate the dehumidification
function.
S-FLOW mode

flow is given to the front seats, reducing
the airflow and air conditioning effect
on the rear seats. When in S-FLOW
mode, airflow from the rear air condi-
tioning system is stopped. (RX450hL)

according to the following conditions:
 Priority is given to the driver's seat
only when:
Manual S-FLOW mode: When no
passenger is judged to be in the
front passenger seat.
Automatic S-FLOW mode: When
no passengers are judged to be in
the front passenger seat or rear
seats.
