ates automatically.

: This item cannot be selected when the

air conditioning is off.

■

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.

The defoggers will automatically turn off
after 15 minutes.

■

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 power switch is

turned to 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. 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

automatically switch regardless of the air

conditioning setting depending on the

temperature setting or inside tempera-

ture.

■

Registering air conditioning settings to

electronic keys

●

Unlocking the vehicle using an electronic

key and turning the power switch to ON

mode will recall that key’s registered air

conditioning settings.

●

When the power 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 the

passenger door.

●

Vehicles with the driving position mem-

ory: The doors that can recall the air con-

ditioning setting

when unlocked using

the smart access system with push-but-

ton start can be changed. For details,

contact your Lexus dealer.

: 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

(



P.269)

●

Adjust the fan speed

●

Turn off Eco drive mode (



P.218)

■

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

system. This may then cause odor to be

emitted from the vents.

●

To reduce potential odors from occur-

ring, 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.

■

Using the Intelligent Assistant

Air conditioning system can be operated

using voice commands. For details, refer to

the “MULTIMEDIA OWNER’S MAN-

UAL”.

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 12-volt battery discharge

Do not leave the air conditioning system

on longer than necessary when the

hybrid system is off.

■

When repairing/replacing parts of

the air conditioning system

Have repair/replacement performed by

your Lexus dealer. When a part of the air

conditioning system, such as the evapo-

rator, is to be replaced, it must be

replaced with a new one.

than that operated is maintained.

■

Using automatic mode

Fan speed is adjusted automatically

according 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.
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. The next time the dehumidification

function is turned off, the automatic mode

for switching between outside air and recir-

culated air modes is canceled.

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

While operating, the indicator on the
switch will turn on.

■

Manually turning front seat con-
centrated airflow mode on/off

Operation of automatic airflow control

●

In order to maintain a comfortable inte-

rior, airflow may be directed to seats

without passengers immediately after the

hybrid system is started and at other

times depending on the outside tempera-

ture.

●

After the hybrid system is started, if pas-

sengers move around inside or enter/exit

the vehicle, the system cannot accurately

detect the presence of passengers and

automatic airflow control will not oper-

ate.

■

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

With the indicator off, turn the power

switch off.

After 60 minutes or more elapse, turn

the power switch to ON mode.

To turn on the “Sync” mode, select the
“Sync” on the air conditioning control
screen.

The driver’s side temperature control
switches can be used to adjust the tem-
perature for the driver’s seat and passen-
ger’s seat side. To enter individual mode,
