■

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. Pressing

“A/C” button or selecting “A/C” 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.

■

Outside/recirculated air mode

●

When driving on dusty roads such as tun-

nels or in heavy traffic, set the outside/

recirculated air mode switch to the recir-

culated air mode. This is effective in pre-

venting outside air from entering the

vehicle interior. During cooling opera-

tion, setting the recirculated air mode will

also cool the vehicle interior effectively.

●

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 posi-

tion memory are changed at the same
time.

■

Operation of the air conditioning sys-

tem in Eco mode

●

In the Eco 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

• Adjust the temperature setting

• Turn off Eco mode

●

Even when the driving mode is set to Eco

mode, the air conditioning eco mode can

be turned off by selecting the

.

■

When the outside temperature is low

The dehumidification function may not

operate even when “A/C” is pressed or “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-

WARNING

■

To prevent the windshield from fog-

ging up

●

Do not use the front windshield defog-

ger switch during cool air operation in

extremely humid weather. The differ-

ence 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.

■

To prevent burns

●

Do not touch the rear view mirror sur-

faces when the outside rear view mir-

ror defoggers are on.

●

Vehicles with windshield wiper de-

icer: Do not touch the glass at lower
