Changing the air flow mode
 P.316 ■
Switching between outside air and
recirculated air modes
Press the outside/recirculated air
mode switch. The mode changes as follows each time
the switch is pressed.
automatic mode  (outside air
mode)  (recirculated air mode)
 automatic mode
When the system is switched to automatic
mode, the air conditioning system operates
automatically. ■
Defogging the windshield
Defoggers are used to defog the wind-
shield and front side windows.
Press the windshield defogger switch. Set the outside/reci rculated 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 quickly, turn the air flow and tem-
perature 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 a while. The operation time changes
according to the ambient temperature and
vehicle speed. ■
Windshield wiper de-icer (if
equipped)
 P.319 ■
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. ●
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. ■
Outside/recirculated air mode ●
When driving on dusty roads such as tun-
nels or in heavy traffic, set the out-
side/recirculated air mode switch to the
recirculated air mode. This is effective in
preventing outside air from entering the
vehicle interior. During cooling opera-
tion, setting the recirc ulated air mode will
also cool the vehicle interior effectively.
●
Outside/recirculated air mode may auto-
matically switch depending on the tem-
perature setting or the inside
temperature.
■
Registering air conditioning settings to
electronic keys
●
Unlocking the vehicle using an electronic
key and turning the engine switch to
IGNITION ON mode will recall that
key’s registered air conditioning settings.

3155-3. Using the air conditio ning system and defogger
LS500_OM_(U)_1810 5
Interior features ●
When the engine 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 electr onic key is in the
vicinity or if the smart access system with
push-button start is used to unlock a pas-
senger door.●
The doors that can recall the air condi-
tioning 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.■
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 restri ct heating/cooling
capacity●
Fan speed restricted when automatic
mode is selected
To improve air condit ioning performance,
perform the following operations: ●
Turn off eco air conditioning mode
(  P.316) ●
Adjust the fan speed●
Turn off Eco drive mode (  P.289)
■
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 sys-
tem. This may then cause odor to be
emitted from the vents.
●
To reduce potential odors from occur- ring:
• 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 pe riod of time imme-
diately after the air conditioning system is
started in automatic mode or with the
micro dust and pollen filter on. ●
When parking, the system automatically
switches to outside air mode to encour-
age better air circulation throughout the
vehicle, helping to reduce odors that
occur when starting the vehicle. ■
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”. ■

Customization
Some functions can be customized.
(  P.466)
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.

proof coating deteriorates. If water does not bead on a clean surface,
apply wax when the vehicle body is cool.
■
Self-restoring coat
The vehicle body has a self-restoring coat-
ing that is resistant to small surface
scratches caused in a car wash etc.
●
The coating lasts for 5 to 8 years from
when the vehicle is delivered from the
plant.
●
The restoration time differs depending on
the depth of the scratch and outside tem-
perature.
