AIR CONDITIONING This button allows the air intake to select OUTSIDE AIR mode automatically. This is to clean up the front view more quickly. It is not possible to return to RECIRCULATED AIR mode in the windshield air flow mode. Push the "A/C" button for dehumidified heating or cooling. This setting clears the front view more quickly. (c) Operating tips D 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. D Make sure the air inlet grilles in front of the windshield are not blocked by leaves or other obstructions. D If air flow control is not satisfactory, check the side vents and rear vents. (See "(d) Side vents and rear vents".) D 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. D Keep the area under the front seats clear to allow air to circulate throughout the vehicle. D 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. D 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 "OFF". 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. 189
