—Checking and replacing the  
air conditioning filter  
Air conditioning filter—  
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 “Owner’s Manual Sup-  
plement/Scheduled Maintenance”.)  
The air conditioning filter information  
label is placed on the left side of the  
glove box as shown and indicates that  
a filter has been installed.  
The air conditioning filter is set behind  
the glove box.  
The air conditioning filter prevents dust  
from entering the vehicle through the air  
conditioning vent.

tioning with the air filter removed  
may cause deteriorated dustproof per-  
formance and then affect air condi-  
tioning performance.  
4. Remove the filter from the filter case  
and replace it with a new one.
