■S-FLOW mode
In S-FLOW mode, priority for the airflow 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. (RX350L)
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.

■Registering air conditioning settings to electronic keys (vehicles with driving position
memory)
●Unlocking the vehicle using an electronic ke y and turning the engine switch to IGNI-
TION ON mode will recall that key’s re gistered air conditioning settings.
●When the engine switch is turned off, the current air conditioning settings will automat-
ically be registered to the electronic key that was used to unlock the vehicle.
●The system may not operate correctly if more th an one electronic key is in the vicinity or
if the smart access system with push-button start is used to unlock a passenger door.
●The doors that can recall the air conditioning setting when unlocked using the smart
access system with push-button start can be changed.* For details, contact your Lexus
dealer.
*: The doors that can recall the driving positi on memory are changed at the same time.

ent conditions.
Therefore, the fan may stop for a while until wa rm or cool air is ready to flow immediately
after the “AUTO” button is pressed or “AUTO” is selected.
■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 (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 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.
