WARNING
■To prevent the windshield from fog-
ging up
Do not use the windshield defogger
switch during cool air operation in
extremely humid weather. The difference
between the temperature of the outside
air and that of the windshield can cause
the outer surface of the windshield to fog
up, blocking your vision.
■When the outside rear view mirror
defoggers are operating
Do not touch the outside rear view mir-
ror surfaces, as they can become very
hot and burn you.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system
on longer than necessary when the
engine is off.
■When repairing/replacing parts of
the air conditioning system
Have repair/replace ment performed by
your Lexus dealer.
When a part of the air conditioning sys-
tem, such as the evaporator, is to be
replaced, it must be replaced with a new
one.

driving mode select switch, eco air condi-
tioning mode turns on.
When a drive mode other than Eco drive
mode is selected, eco air conditioning
mode may turn off.
■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/recirculat ed air mode may not
switch to (recirculated air) mode.
Pollen is filtered even if the micro dust and
pollen filter is turned off.
1 Press the automatic mode switch.
2 Press the outside/recirculated air
mode switch to switch to automatic
air intake mode.
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.
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 that 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
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.
This function automatically controls the
air conditioning airflo w so that priority
is given to the front seats. When the
front passenger seat is not occupied,
airflow may switch to only the driver's
seat. Unnecessary air conditioning is
suppressed, contributing to increased
fuel efficiency.
Front seat concentrated airflow mode
operates in the following situations.
 No passengers are detected in the
rear seats
 The windshield defogger is not
operating
 Pollen removal mode is not operat-
ing
WARNING
■To prevent burns (vehicles with wind-
shield wiper de-icer)
Do not touch the glass at lower part of
the windshield or to the side of the front
pillars when the wind shield wiper de-icer
is on.

■Manually turning front seat con-
centrated airflow mode on/off
In front seat concentrated airflow
mode, directing airflow to the front
seats only and to all seats can be
switched via switch operation. When
the mode has been switched manually,
automatic airflow control stops operat-
ing.
Select on the option control
screen ( P.328) and switch the air-
flow.
 Indicator illuminated: Airflow to the
front seats only
 Indicator off: Airflow to all the seats.
■Operation of automatic airflow control
●In order to maintain a comfortable inte-
rior, airflow may be directed to seats
without passengers immediately after the
engine is started and at other times
depending on the outside temperature.
●After the engine is st arted, if passengers
move around inside or enter/exit the vehi-
cle, the system cannot accurately detect
the presence of passengers and auto-
matic airflow control will not operate.
■Operation of manual airflow control
Even if the function is manually switched to
directing airflow to only the front seats,
when a rear seat is occupied, it may auto-
matically direct airflow to all seats.
■To return to automa tic airflow control
1 With the indicator off, turn the engine
switch off.
2 After 60 minutes or more elapse, turn
the engine switch to IGNITION ON
mode.
