(b) Windshield defogging and defrosting
G21010
To remove interior fog on the windshield—
Push the windshield air flow button.
To remove frost or exterior fog on the windshield—
1. Push the “TEMP” (”
”) button to set the “MAX HOT”.
2. Push the windshield air flow button.
3. Touch fan speed control switch on the right side to obtain a
maximum air flow.
4. Leave the “A/C” switch off.When the windshield air flow button is pushed while operating
in automatic mode, the air conditioning is set to operate and the
OUTSIDE AIR mode is set.
If you push the windshield air flow button once again while in
the windshield air flow mode, the mode then returns to the last
mode used.
CAUTION
Do not use the windshield air flow button during cooled
air operation in extremely humid weather. The
difference between the temperature of the outside air
and that of the windshield could cause the outer surface
of the windshield to fog up blocking your vision.

(c) Micro dust and pollen filter
This vehicle is equipped with a micro dust and pollen filter
mode. When this mode is activated, air from the vents will
remove pollen on the driver and passengers.
G21073
Push the micro dust and pollen filter button.
The indicator light and “A/C” switch come on and
RECIRCULATED AIR mode is turned on. Air is delivered from
the instrument panel vents to the areas near the driver and
passengers to remove pollen on them.
When the interior is purified sufficiently with fresh air (after
about 3 minutes at normal outside temperature and about 1
minute at low outside temperature), this mode will be turned off
automatically and the indicator light will go out.
When the micro dust and pollen filter is activated, this mode will
be turned off by pushing the micro dust and pollen filter button
again. The indicator light will also go out.
INFORMATION
Use this mode to remove pollen quickly carried by the
driver or passengers or through the window in the
days with much pollen.
Use and push the windshield air flow button to
remove the fog on the windshield in rainy days.
Fresh air is delivered even when the micro dust and
pollen filter button is turned off.

(d) Operating tips
To help cool down the interior after parking in the hot sun,
drive for the first few minutes with the windows open. After
the excess heat has blown away, close the windows.
Make sure the air inlet grilles in front of the windshield are
not blocked by leaves or other obstructions.
If air flow control is not satisfactory, check the dashboard
vents and rear vents. (See (e) “Center vents, side vents and
rear vents”.)
Only humid days, do not blow cold air on the windshield.
The windshield could fog up because of the difference in air
temperature on the inside and outside of the windshield.
Keep the area under the front seats clear to allow air to
circulate throughout the vehicle.
On cold days, set the fan speed to high for a minute to help
clear the intake ducts of snow or moisture. This can reduce
the amount of fogging on the windows.
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
control button be set to the OUTSIDE AIR mode to take in
the fresh air and the fan speed selector to any setting except
OFF.If following another vehicle on a dusty road, or driving in
windy and dusty conditions, it is recommended that the air
intake control button be temporarily pressed in to the
RECIRCULATED AIR mode, which will close off the outside
passage and prevent outside air and dust from entering the
vehicle interior.

When the windshield air flow button is pushed, air flows mainly
from the windshield vents and turns on the defogging function
with the purpose of clearing the front view.
Pushing this button once again returns the air flow mode to the
last one used.
This button allows the air intake to select OUTSIDE AIR mode
automatically. This is to clean up the front view more quickly.
If you want to return the setting to RECIRCULATED AIR mode,
push the air intake control button once again.Touch the “A/C” switch for dehumidified heating or cooling.
This setting clears the front view more quickly.
Only humid days, do not blow cold air on the
windshield—the difference between the outside and inside
temperatures could make the fogging worse.

(f) Replacing the air conditioning filter
G21011
The air conditioning filter information label is placed in the
glove box as shown and indicates that a filter has been
installed.
The air conditioning filter, in addition to removing odors,
prevents dust and pollen from entering the vehicle through the
air conditioning vent.

G21012
The air conditioning filter is behind the glove box.
The air conditioning filter may clog after long use. The filter
may need to be replaced if the air flow of the air conditioning
and heater experiences extreme reductions in operating
efficiency, or if the windows fog up easily.
If the symptoms of air conditioning efficiency problems occur,
contact your nearest Lexus dealer to have the filter replaced.
To maintain the air conditioning efficiency, replace the air
conditioning filter according to the maintenance schedule. In
dusty areas or areas with heavy traffic flow, such as inner city
or desert areas, early replacement may be required. (For
scheduled maintenance information, see the “Owner’s Manual
Supplement / Scheduled Maintenance”).1. Turn the air intake control to RECIRCULATED AIR
mode.
The filter case cannot be removed in the OUTSIDE AIR mode.
2. Turn off the engine switch.
3. When you replace the filter, be sure to turn off the fan.G21013

NOTICE
When setting the filter to the filter case, the UP marks
shown on the filter and filter case should be noted and
fitted as shown.
INFORMATION
The air conditioning filter should be installed properly
in position. The use of air conditioning with the filter
removed may cause deteriorated dustproof perfor-
mance and then affect air conditioning performance.
