AIR CONDITIONING
200This button allows the air intake to select OUTSIDE AIR mode
automatically. This is to clean up the front view more quickly.
If you want to return the setting to RECIRCULATED AIR mode,
push the air intake control button once again.
Push the A/Cº button for dehumidified heating or cooling. This
setting clears the front view more quickly.
CAUTION
Do not use the windshield air flow button during cooled
air operation in extremely humid weather. The
difference between the temperature of the outside air
and that of the windshield could cause the outer surface
of the windshield to fog up blocking your vision.
(c) Operating tips
To help cool down the interior after parking in the hot sun,
drive for the first few minutes with the windows open. After
the excess heat has blown away, close the windows.
Make sure the air inlet grilles in front of the windshield are
not blocked by leaves or other obstructions.
If air flow control is not satisfactory, check the side vents and
rear vents. (See (d) Side vents and rear ventsº.)
On humid days, do not blow cold air on the windshield. The
windshield could fog up because of the difference in air
temperature on the inside and outside of the windshield.
Keep the area under the front seats clear to allow air to
circulate throughout the vehicle.
On cold days, set the fan speed to high for a minute to help
clear the intake ducts of snow or moisture. This can reduce
the amount of fogging on the windows.
When driving on dusty roads, close all windows. If dust
thrown up by the vehicle is still drawn into the vehicle after
closing the windows, it is recommended that the air intake
be set to the OUTSIDE AIR mode and the fan speed to any
setting except OFFº.

AIR CONDITIONING
201 If following another vehicle on a dusty road, or driving in
windy and dusty conditions, it is recommended that the air
intake be temporarily set to the RECIRCULATED AIR
mode, which will close off the outside passage and prevent
outside air and dust from entering the vehicle interior.Heating

AIR CONDITIONING

(e) Checking and replacing the air conditioning
filter
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 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 begin to fog up easily.
To maintain the air conditioning efficiency, inspect and 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, please
refer to the Owner's Manual Supplement/Scheduled
Maintenanceº.)
