■ 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 passenger 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 pas-
senger door is detected, the system will
judge that a passenger is not in the front
passenger seat after the vehicle 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 closing of a rear door or the
operation of the rear air conditioning sys-
tem (RX350L).
If a passenger is judged to be in the vehicle,
the system will retain the judgement for a
certain amount of time after the engine
switch is turned off.
■ Operation of automatic S-FLOW mode
When the system is operating in automatic
S-FLOW mode, if the system detects the
opening and closing of a rear door or the
operation of the rear air conditioning sys-
tem (RX350L), S-FLOW mode will be dis-
abled. To enable S-FLOW mode, select the
S-FLOW mode switch. (In this case, the sys-
tem will operate in manual S-FLOW mode.)
■ Changing from manual S-FLOW mode

1 Select the S-FLOW mode switch to dis-
able S-FLOW mode.
2 Turn the engine switch off.
3 After 60 minutes have elapsed, change
the engine switch to ON mode.
