This feature is used to prevent ice from
building up on the windshield and wiper
blades.
The windshield de-icer will automatically
turn off after a while.
■Micro dust and pollen filter
Outside air mode switches to
(recirculated air) mode. Pollen is removed
from the air and the air flows to the upper
part of the body.
Usually the system will automatically turn
off after a while.
In order to prevent the windshield from fog-
ging up when the outside air is cold, the
dehumidification function may operate or
the outside/recirculated air mode may not
switch to (recirculated air) mode.
Pollen is filtered even if the micro dust and
pollen filter is turned off.

1Press the automatic mode switch or
select “AUTO” on the sub function
menu. ( P.300)
2 Press the outside/recirculated air
mode switch to switch to automatic
air intake mode. (if equipped)
The air conditioning system automatically
switches between outside air and recircu-
lated air modes.
3Adjust the temperature setting.
4 To stop the operation, press the off
switch or select “OFF” on the sub
function menu. ( P.300)
If the fan speed settin g or air flow modes
are operated, the automatic mode indica-
tor goes off. However, automatic mode for
functions other than th at operated is main-
tained.
■Using automatic mode
Fan speed is adjusted automatically accord-
ing to the temperature setting and the
ambient conditions.
Therefore, the fan may stop for a while until
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.
■Automatic mode for air intake control (if
equipped)
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.
In S-FLOW mode, priority for the air-
flow is given to the front seats, reducing
the airflow and air co nditioning effect
on the rear seats. When in S-FLOW
mode, airflow from the rear air condi-
tioning system is stopped. (RX350L)
Operation in S-FLOW mode differs
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.
 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 disabled
when: A passenger is judged to be
in a rear seat when in automatic
S-FLOW mode.
Depending on the set temperature, opera-
tion in S-FLOW mode may not change as
described above.
When certain conditions are met and pri-
ority is given to the driver’s seat only, the
temperature indicator for the front passen-
ger side will turn off.
How the system judges if a passenger is in
the vehicle: P.305

Manual S-FLOW mode
When the S-FLOW mode switch is
selected, S-FLOW mode will be manu-
ally enabled/ disabled.
The indicator will illuminate on the air con-
ditioning control screen when S-FLOW
mode is enabled.
In manual S-FLOW mode, as the system
does not judge if a pa ssenger is in a rear
seat.
To disable S-FLOW mode automatically by
opening and closing a rear door or operat-
ing the rear air conditioning system
(RX350L), change to automatic S-FLOW
mode. ( P.305)
■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 dete
cted, 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. (I n this case, the sys-
tem will operate in manual S-FLOW mode.)
■Changing from manual S-FLOW mode
to automatic 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
