Windshield wiper de-icer (if equipped)

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.

■

Pollen removal mode

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 pollen removal

mode is turned off.

■

nanoe™ X

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™ X

on the option control screen is selected,

the nanoe™ X 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™ X 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.

: nanoe™ X is a nanoe™ generator.

: 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.

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 windshield wiper de-icer

is on.

■

nanoe™ X

Do not disassemble or repair the genera-

tor because it contains high voltage

parts. Contact any authorized Lexus

retailer or Lexus authorized repairer, or

any reliable repairer if the generator

needs repair.

NOTICE

■

To prevent damage to the nanoe™ X

Do not insert anything into the driver’s

side vent, attach anything to it, or use

sprays around the driver’s side vent.

These things may cause the generator

not to work properly.

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.

Adjust the temperature setting.

To stop the operation, press the off
switch.

If the fan speed setting 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 airflow 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, the indicator is turned
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.

■

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.

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.
