RECIRC: When RECIRC is selected, the system will limit the amount of outside air entering your vehicle. This is helpful when you are trying to cool the interior of the vehicle quickly or limit the amount of outside air entering your vehicle for someother reason. RECIRC and AUTO may be selected at the same time. The system will remain in RECIRC until the ignition is turned off. The systemwill return back to thepreviously selected mode when the car isturned back on. RECIRC can be selected in all manual airflow modes except FRONT defrost. RECIRC cannot be selected with the VENT button. 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, thesystem 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 theAUTO 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. FRONT This selection is used to defrost the windshield by directing the airflow toward the windshield. If FRONT is selected while inthe AUTO mode, the fan i speed and thea r temperature from the front defroster will vary. If a manual fan speed setting selected, the fan is speed will remainat that selection until another fan speed selection is made or the AUTO mode selected. To turn is off FRONT, press the AUTO or AIR FLOW button. FRONT defrost will work better if any ice or snow is cleared from the hood and the air inlet area between the base of the windshield and the hood. Heating Press AUTO and adjust the temperature by pressing the TEMP up or down arrow. You may also adjust the dual automatic 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 will be brought in and sent through the floor outlets. The heater works best if you keep your windows closed. 3-5
