Only humid days, do not blow cold air on the
windshield—the dif ference between the outside and inside
temperatures could make the fogging worse.
—The outside of the windshield
For best results, set controls to:
For automatic operation—
Temperature— Towards high temperature
Air intake—OUTSIDE AIR
Air flow—WINDSHIELD
For manual operation—Fan speed—To the desired fan speed
Temperature— Towards high temperature
Air intake—OUTSIDE AIR
Air flow—WINDSHIELD
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.

If air flow control is not satisfactory, check the center
vents, side vents and rear vents. They may be opened or
closed as shown.
When outside temperature is low like a winter season, air flow
temperature from the center vents, side vents and rear vents
may not be warmed up enough for a while until the engine
coolant temperature becomes high enough.
If air flow from the center vents, side vents and rear vents is not
satisfactory, air flow direction can be changed manually by
adjusting the vents fin direction or the vents may be closed.

(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 cleaned or
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”).
