Registering air conditioning settings to electronic keys

●

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 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.
Settings for the electronic key and the corresponding door can be changed.

Contact your Lexus dealer.

■

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 the “AUTO” button is pressed.

■

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

■

Fogging up of the windows

●

The windows will easily fog up when the humidity in the vehicle is high. Touching “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.

5-1. Using the air conditioning system and defogger

■

Automatic mode for air intake control (vehicles with rear air conditioning system)
In automatic mode, the system detects exhaust gas and other pollutants and automati-

cally 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.

■

When the outside temperature is low
The dehumidification function may not operate even when “A/C” is touched.

■

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.

CAUTION

■

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. (vehicles with windshield wiper de-icer)

NOTICE

■

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

off.

●

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.
