■
Registering air conditioning settings to electronic keys
●
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.
●
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
is pressed.
Cool air may blow around the upper body even when the heater is on due to sunlight.
■
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
on.
●
It is possible to switch to outside air mode at any time by pressing
.
■
Automatic mode for air intake control
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.
■
Operation of the air conditioning system in Eco drive mode
In the 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:
●
Turn off eco air conditioning mode
●
Adjust the fan speed
●
Turn off Eco drive mode (
■
Eco air conditioning mode
When Eco drive mode is selected using the drive mode select switch, eco air condition-
ing mode turns on.
When a drive mode other than Eco drive mode is selected, eco air conditioning mode
may turn off.
■
When the S-FLOW mode operates
If air flows to the driver’s seat only, the temperature setting for the front passenger’s seat
is not displayed.
■
When the outside temperature is low
The dehumidification function may not operate even when “A/C” on the option control
screen 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.
●
Vehicles with windshield wiper de-icer: 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.
