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 prevents dust
from entering the vehicle through the air
conditioning vent.The air conditioning filter is behind the
glove box.
The air conditioning filter may clog af-
ter long use. The filter may need to be
replaced if the air flow of the air condi-
tioning and heater experiences extreme
reductions in operating efficiency, or if
the windows begin to fog up easily. To maintain the air conditioning efficiency,
inspect and replace the air conditioning
filter according to the maintenance sched-
ule. 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,
please refer to the “Scheduled Mainte-
nance Guide” or “Owner ’s Manual Supple-
ment”.)
