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.
