■S-FLOW mode
In S-FLOW mode, priority for the airflo w 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 condit ioning system is stopped. (RX450hL)
Operation in S-FLOW mode differs according to the following conditions: • Priority is given to the driver’s se at only when: Manual S-FLOW mode:
When no passenger is judged to be in the front passenger seat.
Automatic S-FLOW mode: When no passeng ers are judged to be in the front
passenger seat or rear seats. • Priority is given to the front seats when: Manual S-FLOW mode is selected
or no passengers are judged to be in the rear seats when in automatic S-
FLOW mode.
• S-FLOW mode will be disa bled when: A passenger is judged to be in a rear
seat when in automatic S-FLOW mode.
Depending on the set temperature, operation in S-FLOW mode may not
change as described above.
When certain conditions are met and priori ty is given to the driver’s seat only,
the temperature indicator for the fr ont passenger side will turn off.
How the system judges if a passenger is in the vehicle: P. 518
The following S-FLOW modes are available:
Automatic S-FLOW mode
In this mode, when a passenger is judg ed to be in a rear seat, S-FLOW mode
will be automatically disabled.

■How the system judges if a passenger is in the vehicle when in S-FLOW mode
In S-FLOW mode, the system judges if a passenger is in the vehicle as follows:
• Front passenger seat: A passeng er is judged to be in the front passenger seat when the
system detects an object on the front passenger seat, fastening of the front passenger
seat belt, changing of the set temperature for the front passenger seat or the opening
and closing of the front passenger door. (However, when only opening and closing of
the front passenger door is detected, the sy stem will judge that a passenger is not in
the front passenger seat after the vehicl e speed reaches approximately 12 mph (20
km/h) or more.)
• Rear seats (automatic S-FLOW mode only): A passenger is judged to be in a rear seat
when the system detects the opening and closin g of a rear door or the operation of the
rear air conditioning system (RX450hL).
If a passenger is judged to be in the vehicl e, the system will retain the judgement for a
certain amount of time after th e power switch is turned off.
■Operation of automatic S-FLOW mode
When the system is operating in automati c S-FLOW mode, if the system detects the
opening and closing of a rear door or the op eration of the rear air conditioning system
(RX450hL), S-FLOW mode will be disabled. To enable S-FLOW mode, select
on the option control screen. (In this case , the system will operate in manual S-FLOW
mode.)
■Changing from manual S-FLOW mode to automatic S-FLOW mode
Select on the option control screen to disable S-FLOW mode.
Turn the power switch off.
Wait for 60 minutes or more and change the power switch to ON mode.
