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 passe nger 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 (RX350L).
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 engine 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
(RX350L), S-FLOW mode will be disabled . To enable S-FLOW mode, select on
the option control screen. (I n this case, the system w ill operate in manual S-FLOW
mode.) ■
