(e) Checking and replacing the air
conditioning filter
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 conditioner and
heater experiences extreme reductions in operating efficiency,
or if the windows become to fog up easily.
To maintain the air conditioning efficiency, inspect and replace
the air conditioning filter according to the maintenance
schedule. (For scheduled maintenance information, please
refer to the "Owner 's Manual Supplement/Scheduled
Maintenance".)
1. Open the glove box. Remove the screw with a
Phillips head screwdriver.
2. Remove the 2 pins installed on the upper part of the
glove box and lower the glove box.
