MIRROR DEFOGGERS
These features are used to defog the
rear window, and to remove raindrops,
dew and frost from the outside rear view
mirrors.
The “START STOP ENGINE” <“POW-
ER”> switch must be in IGNITION ON
mode.
CAUTION
●When the outside rear view mirror
defoggers are on, do not touch the rear
view mirror surfaces, as they can become
very hot and burn you.
NOTICE
●To prevent 12-volt battery discharge, turn
the defoggers off when the engine is off.
WINDSHIELD WIPER
DE-ICER*
This feature is used to prevent ice from
building up on the windshield and wiper
blades.
The “START STOP ENGINE” <“POW-
ER”> switch must be in IGNITION ON
mode.
CAUTION
●When the windshield wiper de-icer is on,
do not touch the glass at the lower part of
the windshield or to the side of the front

1Select .
zUsually the system will turn off automati-
cally after approximately 1 to 3 minutes.
z 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
capacity
• Fan speed restricted when automatic mode is selected z
To improve air conditioning performance,
perform the following operations:
• Adjust the fan speed and temperature
• Turn off Eco drive mode (refer to
“Owner ’s Manual”.)
z Unlocking the vehicle using an electronic
key and turning the “START STOP
ENGINE” <“POWER”> switch to IGNI-
TION ON mode will recall that key’s
registered air conditioning settings.
z When the “START STOP ENGINE”
<“POWER”> switch is turned off, the cur-
rent 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 vicin-
ity or if the smart access system with push
button start is used to unlock a passenger
door.
Settings for the electronic key and the cor-
responding door can be changed. Contact
your Lexus dealer.
MICRO DUST AND POLLEN

Outside air mode switches to recirculat-
ed air mode. Pollen is removed from the

zFan speed is adjusted automatically
according to the temperature setting and
the ambient conditions.
z Therefore, the fan may stop for a while until
warm or cool air is ready to flow immedi-
ately after “A U T O ” is pressed.
z The windows will easily fog up when the
humidity in the vehicle is high. Selecting
“A / C ” on will dehumidify the air from the
outlets and defog the windshield effectively.
z If “A / C ” is switched off, the windows may
fog up more easily.
z The windows may fog up if the recirculated
air mode is used. z
When automatic mode is set, the humidity
sensor (see page 305) detects fog on the
windshield and controls the air condition-
ing system to prevent fog.
z When driving on dusty roads such as tun-
nels or in heavy traffic, set the outside/
recirculated air mode button to the recircu-
lated air mode. This is effective in prevent-
ing outside air from entering the vehicle
interior. During cooling operation, setting
the recirculated air mode will also cool the
vehicle interior effectively.
z Outside/recirculated air mode may auto-
matically switch depe nding on the temper-
ature setting or the inside temperature.
USING AUTOMATIC MODE
FOGGING UP OF THE
WINDOWS
CAUTION
●To prevent the windshield from fogging
up
• Do not use the windshield air flow but- ton 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 wind-
shield to fog up, blocking your vision.

zIn 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.
z Recirculated air mode is selected as a
default mode when the “START STOP
ENGINE” <“POWER”> switch is turned to
IGNITION ON mode.
z It is possible to switch to outside air mode at
any time by pressing the air intake control
button.
z 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. z
In order to prevent the windshield from fog-
ging up when the outside air is cold, the fol-
lowing may occur:
• Outside air mode does not switch to
recirculated air mode.
• The dehumidification function operates.
• The operation cancels after approxi- mately 1 minute.
z In rainy weather, the windows may fog up.
Press the windshield air flow button.
z In extremely humid weather, the windows
may fog up.
z The pollens are filtered out even if
is
turned off.
z In the following situations, the correct out-
side temperature may not be displayed, or
the display may take longer than normal to
change.
• When stopped, or driving at low speeds
(less than 12 mph [20 km/h])
• When the outside temperature has changed suddenly (at the entrance/exit of
a garage, tunnel, etc.)

zThe dehumidification function may not
operate even when “A / C ” is selected.
z 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.
z To reduce potential odors from occurring:
• It is recommended that the air condition-
ing 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 imme-
diately after the air conditioning system is
started in automatic mode.
z The air conditioning filter may clog after
long use. The filter may need to be
replaced if the air flow of the air conditioner
and heater experiences extreme reduc-
tions in operating efficiency, or if the win-
dows fog up easily. (For details, refer to
“Owner ’s Manual”.) z
Settings can be changed. (For details, refer

NOTICE
●In order to detect fog on the windshield, a
sensor which monitors the temperature
of the windshield, the surround humidity,
etc. is installed. (See page 303.)
Follow these points to avoid damaging
the sensor:
• Do not disassemble the sensor
• Do not spray the glass cleaner on the
sensor or subject it to strong impacts
• Do not stick anything on the sensor
