If you have the rear passenger comfortemp option, you can adjust the direction of the airflow to the rear seating area. Ventilation Tips 0 Keep the hood and front air inlet free of ice, snow or any other obstruction such as leaves. The heater and defroster will work better, reducing the chance of fogging your windows. Keep the air path under the front seats clear of objects. This helps air to circulate throughout your vehicle. If you have the Dual Automatic Comfortemp system, use the FRONT button to defog or defrost the windshield. By choosing thisbutton, the airflow will be directed at the windshield. Adjust your comfort levelby pressing the TEMP up or down arrow. The fan speed will be controlled by the system. You can change the fan speed by pressing the top of the FAN button to increase speed, and the bottom of the button to decrease speed. 0 3-9
