When the windshield air flow button is
pushed, air flows mainly from the wind-
shield 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 RECIR-
CULATED AIR mode, push the air intake
control button once again.
Touch “A/C” for dehumidified heating or
cooling. This setting clears the front view
more quickly.
DOn humid days, do not blow cold air on
the windshield −the difference be-
tween the outside and inside tempera-
tures could make the fogging worse. −

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 cold 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 that 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 ad-
justing the vents fin direction or the vents
may be closed.

(h) Checking and replacing the air
conditioning filter
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 re-
moving odors, prevents dust and pollen
from entering the vehicle through the air
conditioning vent.
The air conditioning filter is behind the
glove box.
The air conditioning filter may clog after
long use. The filter may need to be re-
placed if the air flow of the air conditioner
and heater experiences extreme reduc-
tions in operating efficiency, or if the win-
dows become to fog up easily.
If the symptoms of air conditioning efficien-
cy problems occur, contact your nearest
Lexus dealer to have the filter checked and
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 replace-
ment may be required. (For scheduled
maintenance information, please refer to
the “Owner’s Manual Supplement/Sched-
uled Maintenance”.)
