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 but-
ton to outside air mode if the recirculated
air mode is used. (It may switch automati-
cally.)

■

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

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 restrict heating/cooling

capacity

●

Fan speed restricted when automatic

mode is selected

To improve air conditioning 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.

■

Air conditioning system can be operated

using voice commands. For details, refer to

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 battery discharge

Do not leave the air conditioning system

on longer than necessary when the

engine 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 sys-

tem, such as the evaporator, is to be

replaced, it must be replaced with a new

one.

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.
