The rear window defogger will turn off about 10 minutes after the button is pressed. If you need additional warming time, press the button again. If your vehicle is equipped with heated mirrors this button will activate them. Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger. Repairs would not be covered by your warranty. Operation Tips • Keep the hood and front air inlets free of ice, snow, or any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of your windows. • Keep the air path under the front seats clear of objects. This helps air to circulate throughout your vehicle. • Adding outside equipment to the front of your vehicle, such as hood-air deflectors, etc., may affect the performance of the heating and air conditioning system. Check with your dealer before adding equipment to the outside of your vehicle. Outlet Adjustment Your vehicle has air outlets that allow you to adjust the direction and amount of airflow inside the vehicle. Push the knob in the center of the outlet up, down, left or right to move the outlet in the direction you would like. Turn the knob in the center of the outlet so the louvers open or close to increase or decrease airflow. 3-28
