AIR CONDITIONING When the windshield air flow button is pushed while operating in automatic mode, the air conditioning is set to operate and the OUTSIDE AIR mode is set. This is to clean up the front view more quickly. If you want to return the setting to the RECIRCULATED AIR mode, push the air intake control button once again. Touch the "A/C" switch for dehumidified heating or cooling. This setting clears the front view more quickly. If you push the windshield air flow button once again while in the windshield air flow mode, the mode then returns to the last mode used. (c) Micro dust and pollen filter This vehicle is equipped with a micro dust and pollen filter mode. When this mode is activated, air from the vents will remove pollen on the driver and passengers. Use this mode to remove pollen quickly carried by the driver or passengers or through the window in the days with much pollen. 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. G21073 Push the micro dust and pollen filter button. The indicator light comes on and RECIRCULATED AIR mode is turned on. Air is delivered from the instrument panel vents to the areas near the driver and passengers to remove pollen on them. When the interior is purified sufficiently with fresh air after about 3 minutes, this mode will be turned off automatically and the indicator light will go out. 269
