The air conditioning system removes moisture from the air, so you may sometimes notice a small amount of water dripping underneath your vehicle while idling or after turning off the engine. This is normal. Select one of these available modes from the right knob. 0 (Defog): This mode directs most of the air to the windshield and the floor outlets. A small amount of air is also directed to the outboard outlets for the side windows and to the instrument panel side outlets. When you select this mode, the system runs the air-conditioning compressor. To defog the windows faster, turn the temperature control knob clockwise to the warmest setting. Defogging and Defrosting Fog on the inside of windows is a result of high humidity or 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 your windshield. 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. 1 (Defrost): This mode directs the air to the windshield and the outboard outlets for the side windows. A small amount of air is also directed to the instrument panel side outlets. When you select this mode, the system runs the air-conditioning compressor. To defrost the windows faster, turn the temperature control knob clockwise to the warmest setting. Do not drive the vehicle until all windows are clear. 153
