(d) 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 dashboard
vents. (See ºCenter ventsº and ºSide 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 selector to adjust the fan
speed 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
control button be left to the OUTSIDE AIR mode and the fan
speed control dial be turned to anywhere except the ºOFFº button.
 If following another vehicle on a dusty road, or driving in
windy and dusty conditions, it is recommended that the air
intake control button be temporarily pressed in to the
RECIRCULATED AIR mode, which will close off the outside
passage and prevent outside air and dust from entering the vehicle interior.
