G21008
Each time you push the air intake control button, the mode
changes in order from the RECIRCULATED AIR mode to
AUTOMATIC mode to OUTSIDE AIR mode, then back to the
RECIRCULATED AIR mode. Each indicator light shows which
mode is now selected.
1
RECIRCULATED AIR mode—If quick circulation of
cooled air is desired, select this mode.
2
EXHAUST GAS AUTOMATIC mode—If the outside air
contains harmful substances like exhaust gas (i.e., when
the vehicle running just in front of your vehicle accelerates
rapidly), the system changes automatically from the
OUTSIDE AIR mode (with indicators
2
and 3
on) to
the RECIRCULATED AIR mode (with indicators 1
and 2
on).
3
OUTSIDE AIR mode—The system will take fresh outside
air into the vehicle.Turning off the air conditioning manually will cancel the
EXHAUST GAS AUTOMATIC mode. If you select the “AUTO”
mode during fan operating, the air conditioning turns on and
the EXHAUST GAS AUTOMATIC mode will operate.
For normal use, it is best to keep the air intake control button
set to OUTSIDE AIR mode. If recirculated air is used during
heating, the windows will fog up more easily.

(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.
Heating
For best results, set controls to:
For automatic operation—
Push in the “AUTO” button.
Temperature—To the desired temperature
Air intake—OUTSIDE AIR
Air conditioning—OFF
For manual operation—
Fan speed—To the desired fan speed
Temperature—Towards high temperature
Air intake—OUTSIDE AIR
Air flow—FLOOR
Air conditioning—OFF
For quick heating, select RECIRCULATED AIR mode for a
few minutes. To keep the windows from fogging, select
OUTSIDE AIR mode after the vehicle interior has been
warmed.
Touch the “A/C” switch on for dehumidified heating.
Choose floor/windshield air flow to heat the vehicle interior
while defrosting or defogging the windshield.

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
4. Open the glove box and remove the partition by pulling.
