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 (24C) 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
.

■
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 (0C)
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.
