Defogging the windshield

Defoggers are used to defog the wind-
shield and front side windows.
Press the windshield defogger switch.

Set the outside/recirculated air mode
switch to outside air mode if the recircu-
lated air mode is used. (It may switch auto-
matically.)

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.

Fogging up of the windows

The windows will easily fog up when the

humidity in the vehicle is high. Turning “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

Unlocking the vehicle using an electronic

key and turning the engine switch <power

switch> to IGNITION ON mode <ON

mode> will recall that key’s registered air

conditioning settings.

When the engine switch <power switch>

is turned off, the current air conditioning

settings will automatically 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 entry & start system

is used to unlock the passenger door.

The doors that can recall the air condi-
tioning setting

when unlocked using the

smart entry & start system can be

changed. For details, contact any autho-

rized Lexus retailer or Lexus authorized

repairer, or any reliable repairer.

: The doors that can recall the driving posi-

tion 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 restrict 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 (if

equipped) (



P.345)

Adjust the fan speed

Turn off Eco drive mode (



P.292)

When the outside temperature falls to

nearly 0°C (32°F)

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.

When parking, the system automatically

switches to fresh air intake mode to

encourage better air circulation through-

out the vehicle, helping to reduce odors

that occur when starting the vehicle.

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.

nanoe™ system

This vehicle incorporates a biocidal prod-

uct.
Ionised air generated by a device incorpo-

rated in the vehicle purifies the air in the

cabin by suppressing bacteria.
Active substance: Free radicals generated

in situ from ambient air or water
nanoe™ helps to provide purified air by

emitting electrically charged water parti-

cles through the front center vent on the
driver’s side

When the fan is turned on and nanoe™

on the option control screen is selected,

the nanoe™ system is activated.

When the fan is operated in the following

conditions, system performance will be

maximized. If the following conditions are

not met, performance will be limited.

• The

air outlets are

being used.

• The front center vent on driver’s side is

open.

When nanoe™ is generated, a small

amount of ozone is emitted and may be

faintly smelled in some situations. How-

ever, this is approximately the same as the

amount that already exists in nature, such

as in forests, and it has no affect on the

human body.

A slight noise may be heard during oper-

ation. This is not a malfunction.

: According to temperature and humidity

conditions, fan speed and direction of the
air flow, the nanoe™ system may not
operate at full capacity.

Press the automatic mode switch or
select “AUTO” on the sub function
menu. (

than that operated is maintained.

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.

Windshield fog detection function

When automatic mode is set, the humidity

sensor detects fog on the windshield and

controls the air conditioning system to pre-

vent fog.

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.

To turn on the “DUAL” mode, perform
any of the following procedures:



Select “DUAL” on the sub function
