Defogging and Defrosting Fog on the inside of windows is a result of high humidity (moisture) condensing on the cool window glass. This can be minimized if the climate control system is used properly. There are two modes to clear fog or frost from the windshield and side windows. Use the defog mode to clear the windows of fog or moisture and warm the passengers. Use the defrost mode to remove fog or frost from the windshield more quickly. For best results, clear all snow and ice from the windshield before defrosting. Turn the mode knob on the climate control panel clockwise to select the defog or defrost modes. Outlet Adjustment Use the thumbwheel on the outlets to change the direction of the air flow. Lift up or push down on the thumbwheel located in the center of the outlet to direct the air up or down, or slide the thumbwheel to the left or right to direct the airflow from side-to-side. Operation Tips • Clear away any ice, snow or leaves from the air inlets at the base of the windshield that may block the flow of air into your vehicle. / (Floor/Defog): This mode directs the air to the windshield, the side window outlets, and to the floor outlets. When this mode is selected, the system runs the air conditioning compressor unless the outside temperature is near freezing or below. Recirculation is not available in this mode. • Use of non-GM approved hood deflectors may adversely affect the performance of the system. • Keep the path under the front seats clear of objects to help circulate the air inside of your vehicle more effectively. 0 (Defrost): This mode directs most of the air to the windshield, and the side window outlets. When this mode is selected, the system runs the air conditioning compressor unless the outside temperature is near, or below freezing. Recirculation is not available in this mode. Do not drive the vehicle until all the windows are clear. 3-22
