■

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. 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 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 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-

tem. This may then cause odor to be

WARNING

■

To prevent the windshield from fog-

ging up

Do not use the front 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.

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
