2865-3. Using the air conditioning system and defogger
(outside air mode) modes each
time the button is pressed.
When the system is switched to automatic
mode, the air conditioni ng system operates
automatically.
■Defogging the windshield
Defoggers are used to defog the wind-
shield and front side windows.
Press the windshield defogger switch.
Set the outside/recirc ulated air mode but-
ton to outside air mode if the recirculated
air mode is used. (It may switch automati-
cally.)
To defog the windshield and the side win-
dows early, turn the air flow and tempera-
ture up.
To return to the previous mode, press the
windshield defogger switch again when the
windshield is defogged.
■Defogging the rear window and
outside rear view mirrors
Defoggers are used to defog the rear
window, and to remove raindrops, dew
and frost from the outside rear view
mirrors.
Press the rear window and outside rear
view mirror defoggers switch.
The defoggers will auto matically turn off
after a period of time.

■When the outside temperature exceeds
75°F (24°C) and the air conditioning
system is on
●In order to reduce the air conditioning
power consumption, the air conditioning
system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
●Recirculated air mode is selected as a
default mode when the engine switch is
turned to IGNITION ON mode.
●It is possible to switch to outside air mode
at any time by pressing the outside/recir-
culated air mode switch.
■Fogging up of the windows
The windows will easily fog up when the
humidity in the vehicle is high. Selecting
“A/C” on will dehumidify the air from the
outlets and defog the windshield effectively.
●If you turn “A/C” off, the windows may fog
up more easily.
●The windows may fog up if the recircu-
lated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by the
vehicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake mode be set to outside air
mode and the fan speed to any setting
except off.
■Outside/recirculated air mode
●Setting to the recirculated air mode tem-
porarily is recommended in preventing
dirty air from entering the vehicle interior
and helping to cool the vehicle when the
outside air temperature is high.
●Outside/recirculated air mode may auto-
matically switch depending on the tem-
perature setting or the inside
temperature.
■Registering air conditioning settings to
electronic keys (vehicles with driving
position memory)
●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, con-
tact 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 condit ioning performance,
perform the following operations:
●Adjust the fan speed
●Turn off Eco drive mode ( P.262)
■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.
■Using the voice command system
Air conditioning system can be operated
using voice commands. For details, refer to
“NAVIGATION AND MULTIMEDIA
SYSTEM OWNER’S MANUAL”.
■Air conditioning filter

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
While operating, illuminates.
■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 center display
and switch the airflow.
 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 started, 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 automatic airflow control
1 With the indicator off, turn the engine
switch off.
2 After 60 minutes or more elapse, turn
the engine switch to ON.
Vehicles with DUAL-ZONE climate
control
To turn on the “DUAL” mode, perform

 Select “DUAL” on the sub function
menu. ( P.288)
 Select “DUAL” on the option con-
trol screen.
 Adjust the passenger’s side tem-
perature setting.

WARNING
■To prevent injury
Before performing any light bulb
replacement procedure, be sure to turn
the engine switch off. Failure to do so
may result in burns from hot components
or a part of your body may get caught on
an operating component, possibly caus-
ing serious injury.
■Replacing light bulbs
●Turn off the lights. Do not attempt to
replace the bulb immediately after
turning off the lights.
The bulbs become very hot and may
cause burns.
●Do not touch the glass portion of the
light bulb with bare hands. When it is
unavoidable to hold the glass portion,
use and hold with a clean dry cloth to
avoid getting moisture and oils on the
bulb.
Also, if the bulb is scratched or
dropped, it may blow out or crack.
●Fully install light bulbs and any parts
used to secure them. Failure to do so
may result in heat damage, fire, or
water entering the headlight unit. This
may damage the headlights or cause
condensation to buil d up on the lens.
●Do not attempt to repair or disassem-
ble the light bulbs, connectors, electric
circuits or component parts.
Doing so may result in death or serious
injury due to electric shock.
■To prevent damage or fire
●Make sure bulbs are fully seated and
locked.
●Check the wattage of the bulb before
installing to prevent heat damage.
