Interior features
■Registering air conditioning settings to
electronic keys
●Unlocking the vehicle using an electronic
key and turning the engine switch to
IGNITION ON mode will recall that
key’s registered air conditioning settings.
●When the engine switch is turned off, the
current air conditioning settings will auto-
matically be registered to the electronic
key that was used to unlock the vehicle.
●The system may not operate correctly if
more than one electronic key is in the
vicinity or if the smart access system with
push-button start is used to unlock a pas-
senger door.
●The doors that can recall the air condi-
tioning 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
position memory are changed at the
same time.
■Operation of the air conditioning sys-
tem in Eco drive mode
In Eco drive mode, the air conditioning sys-
tem is controlled as follows to prioritize fuel
efficiency:
●Engine speed and compressor operation
controlled to restri ct heating/cooling
capacity
●Fan speed restricted when automatic
mode is selected
To improve air conditioning performance,
perform the following operations:
●Turn off eco air conditioning mode
(  P.320)
●Adjust the fan speed
●Turn off Eco drive mode ( P.292)
■When the outside temperature falls to
nearly 32°F (0°C)
The dehumidification function may not
operate even when “A/C” is selected.
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning
system to the outside air mode.
●During use, various odors from inside and
outside the vehicle may enter into and
accumulate in the air conditioning sys-
tem. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occur-
ring:
• It is recommended that the air condition-
ing system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be
delayed for a short period of time imme-
diately after the air conditioning system is
started in automatic mode or with the
micro dust and pollen filter on.
●When parking, the system automatically
switches to outside air mode to encour-
age better air circulation throughout the
vehicle, helping to reduce odors that
occur when starting the vehicle.
■Using the voice command system
Air conditioning system can be operated
using voice commands. For details, refer to
the “NAVIGATION AND MULTIMEDIA
SYSTEM OWNER’S MANUAL”.

■Customization
Some functions can be customized.
(  P.470)
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.

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.320)
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 or select “OFF” on the sub
function menu. ( P.320)
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
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
While operating, illumi-
nates.

the windshield or to the side of the front
pillars when the wind shield wiper de-icer
is on.
