Air Conditioning On hot days, open the windows long enough to let hot inside air escape. This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work its best. On very hot days, the system will automatically enter the RECIRC mode and the temperature door will be positioned at the full cold position for maximum cooling. If the system is not in the AUTO mode, RECIRC should be selected to provide maximum cooling. You can choose the extreme comfort setting of 60_F (16_C), but the system will not cool any faster by choosing the extreme comfort setting. Defogging and Defrosting On cool but humid days, use FRONT to keep the windshield and side windows clear and to quickly remove fog, frost or ice from the windshield. The fan speed will vary while in the AUTO mode. If a manual fan speed setting is selected, the fan speed will remain at that selection until the engine is turned off or another selection has been made. To turn off FRONT, press AUTO or AIR FLOW. Rear Window Defogger The lines you see on the rear window warm the glass. Press this button to start warming your window. Heating Press AUTO and adjust the temperature by pressing the TEMP up or down arrow. You may also adjust the ComforTemp system manually by pressing the AIR FLOW button until FLOOR appears. Again, adjust the temperature by pressing the TEMP up or down arrow. Outside air is sent through the floor outlets. The heater works best if you keep your windows closed. 3-6
