ing in dry weather or removing frost or ex-
terior fog on the windshield, turn the air
conditioning off once it is no longer re-
quired. This will improve fuel economy.

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.
To maintain the air conditioning efficiency,
inspect and replace the air conditioning fil-
ter 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.

please refer to the “Warranty and Services
Guide/Owner ’s Manual Supplement/
Scheduled Maintenance”.)1. Open the glove box and unhook the
clip as shown above.
