AIR CONDITIONING
267
(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”.)
