Defogging the windshield
Defoggers are used to defog the wind-
shield and front side windows.
Press the windshield defogger switch.
Set the outside/recirculated air mode
switch to outside air mode if the recircu-
lated air mode is used. (It may switch auto-
matically.)
To defog the windshield and the side win-
dows early, turn the air flow and tempera-
ture up.
To return to the previous mode, press the
windshield defogger switch again when the
windshield is defogged.
■
Defogging the rear window and
outside rear view mirrors
Defoggers are used to defog the rear
window, and to remove raindrops, dew
and frost from the outside rear view
mirrors.
Press the rear window and outside
rear view mirror defoggers switch.
The defoggers will automatically turn off
after 15 minutes.
■
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 power switch is
turned to ON mode.
●
It is possible to switch to outside air mode
at any time by pressing the outside/recir-
culated air mode switch.
■
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 recircu-
lated air mode is used.
■
When driving on dusty roads
Close all windows. If dust thrown up by the
vehicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake mode be set to outside air
mode and the fan speed to any setting
except off.
■
Outside/recirculated air mode
●
Setting to the recirculated air mode tem-
porarily is recommended in preventing

dirty air from entering the vehicle interior
and helping to cool the vehicle when the
outside air temperature is high.
●
Outside/recirculated air mode may
automatically switch regardless of the air
conditioning setting depending on the
temperature setting or inside tempera-
ture.
■
Registering air conditioning settings to
electronic keys
●
Unlocking the vehicle using an electronic
key and turning the power switch to ON
mode will recall that key’s registered air
conditioning settings.
●
When the power switch is turned off, the
current air conditioning settings will auto-
matically 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 the
passenger door.

■
Operation of the air conditioning sys-
tem in Eco drive mode
In Eco drive mode, the air conditioning sys-
tem is controlled as follows to prioritize fuel
efficiency:
●
Engine speed and compressor operation
controlled to restrict heating/cooling
capacity
●
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 (
■
When the outside temperature falls to
nearly 32°F (0°C)
The dehumidification function may not
operate even when “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 accumulate in the air conditioning
system. This may then cause odor to be
emitted from the vents.
●
To reduce potential odors from occur-
ring, the start timing of the blower may be
delayed for a short period of time imme-
diately after the air conditioning system is
started in automatic mode.
●
When parking, the system automatically
switches to fresh air intake mode to
encourage better air circulation through-
out the vehicle, helping to reduce odors
that occur when starting the vehicle.
■
Using the Intelligent Assistant
Air conditioning system can be operated
using voice commands. For details, refer to
the “MULTIMEDIA OWNER’S MAN-
UAL”.

WARNING
■
To prevent the windshield from fog-
ging up
Do not use the windshield defogger
switch during cool air operation in
extremely humid weather. The difference
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.
■
When the outside rear view mirror
defoggers are operating
Do not touch the outside rear view mir-
ror surfaces, as they can become very
hot and burn you.
NOTICE
■
To prevent 12-volt battery discharge
Do not leave the air conditioning system
on longer than necessary when the
hybrid system is off.
■
When repairing/replacing parts of
the air conditioning system
Have repair/replacement performed by
your Lexus dealer. When a part of the air
conditioning system, such as the evapo-
rator, is to be replaced, it must be
replaced with a new one.

than that operated is maintained.
■
Using automatic mode
Fan speed is adjusted automatically
according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until
warm or cool air is ready to flow immedi-
ately after the automatic mode switch is
pressed.
Cool air may blow around the upper body
even when the heater is on due to sunlight.
■
Windshield fog detection function
When automatic mode is set, the humidity
sensor detects fog on the windshield and
controls the air conditioning system to pre-
vent fog.
■
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. The next time the dehumidification
function is turned off, the automatic mode
for switching between outside air and recir-
culated air modes is canceled.
This function automatically controls the
air conditioning airflow so that priority
is given to the front seats. When the
front passenger seat is not occupied,
airflow may switch to only the driver’s
seat. Unnecessary air conditioning is
suppressed, contributing to increased
fuel efficiency.
Front seat concentrated airflow mode
operates in the following situations.
No passengers are detected in the
rear seats

Operation of automatic airflow control
●
In order to maintain a comfortable inte-
rior, airflow may be directed to seats
without passengers immediately after the
hybrid system is started and at other
times depending on the outside tempera-
ture.
●
After the hybrid system is started, if pas-
sengers move around inside or enter/exit
the vehicle, the system cannot accurately
detect the presence of passengers and
automatic airflow control will not oper-
ate.
■
Operation of manual airflow control
Even if the function is manually switched to
directing airflow to only the front seats,
when a rear seat is occupied, it may auto-
matically direct airflow to all seats.
