■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 ke y’s registered air conditioning settings.
●When the power switch is turned off, the current air conditioning settings will automati-
cally 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 entry & start system is used to unlock a passenger door.
●The doors that can recall the air conditioning setting when unlocked using the smart entry & start system can be changed.* For details, contact any authorized Lexus
retailer or Lexus authorized re pairer, or any reliable repairer.
*: The doors that can recall the driving position memory are changed at the same time.
■Using automatic mode
Fan speed is adjusted automatically accordin g to the temperature setting and the ambi-
ent conditions.
Therefore, the fan may stop for a while until wa rm or cool air is ready to flow immediately
after is pressed or “AUTO” is selected.
■Fogging up of the windows
The windows will easily fog up when the hu midity 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 ai r mode. This is effective in preventing out- side air from entering the vehicle interi or. During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automa tically switch depending on the tempera-
ture setting or the inside temperature.
■Operation of the air conditioni ng 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 performanc e, perform the following operations:
●Adjust the fan speed
●Turn off Eco drive mode

■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 dela yed for a short period of time immediately
after the air conditioning system is started in automatic mode.

■Customization
Settings (e.g. A/C Auto switch operation) can be changed. (Customizable features: P. 663)
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 12-vol t battery discharge
Do not leave the air conditioni ng system on longer than necessary when the hybrid sys- tem is off.
●Do not place anything on the instrumentpanel which may cover th e air outlets. Other-
wise, air flow may be obstructed, preventing
the windshield defoggers from defogging.
