AIR CONDITIONING AND AUDIO CAUTION Do not use the FRONT WINDSHIELD mode 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. If quick heating or cooling is desired - Obtain maximum power by turning the "TEMP" knob fully. At this time, "MAX. HOT" or "MAX. COLD" will appear on the display. If manual fan speed control is desired - The fan speed can be set to your desired speed by pushing either side (FAN) button. The higher the fan of the fan speed control (OFF) speed is, the more air is delivered. Pushing in the button turns off the fan. To remove exterior windshield frost, use the high speed setting. 113
