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 IGNI-

TION ON mode will recall that key's registered air conditioning settings. 

●

When the engine switch is turned off, the current air conditioning settings will automat-

ically 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 passenger door. 

●

The doors that can recall the air conditioning setting* when unlocked using the smart

access system with push-button start can be changed. For details, contact your Lexus

dealer. 

*: The doors that can recall the driving position memory are changed at the same time.

■

Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the ambi-

ent conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow immediately
after 

 is pressed or “AUTO” is selected.

■

Using the voice command system
Air conditioning system can be operated using voice commands. For details, refer to the

“NAVIGATION AND MULTIMEDIA SYSTEM OWNER’S MANUAL”.

■

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 recirculated air mode is used.

■

Outside/recirculated air mode

●

When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recircu-

lated air mode button to the recirculated air mode. This is effective in preventing out-

side air from entering the vehicle interior. During cooling operation, setting the

recirculated air mode will also cool the vehicle interior effectively.

●

Outside/recirculated air mode may automatically switch depending on the tempera-

ture setting or the inside temperature.

■

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 consump-

tion.

●

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 

.

5-1. Using the air conditioning system

RC F_U

■

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.

■

Operation of the air conditioning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to prioritize fuel

efficiency:

●

Engine speed and compressor operation controlled to restrict heating/cooling capac-

ity

●

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

■

When the outside temperature falls to nearly 32

F (0C)

The dehumidification function may not operate even when 

 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 accu-

mulate in the air conditioning system. This may then cause odor to be emitted from the

vents.

●

To reduce potential odors from occurring:
• It is recommended that the air conditioning 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 immediately

after the air conditioning system is started in automatic mode.

WARNING

■

To prevent the windshield from fogging up 

●

Do not use 

 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 surfaces when the outside rear view mirror defog-

gers are on.

●

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.

NOTICE

■

To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine is

stopped.

●

Do not place anything on the instrument

panel which may cover the air outlets. Other-

wise, air flow may be obstructed, preventing

the windshield defoggers from defogging.
