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. Rear Climate Control System The lower buttons on the rear seat audio are used to adjust the rear seat climate controls. The temperature of the air coming through the rear outlets is determined by the front passenger's temperature setting. • When you enter a vehicle in cold weather, turn the fan knob all the way to the right for a few moments before driving. This helps clear the intake ducts of snow and moisture, and reduces the chance of fogging the inside of your window. • 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, may affect the performance of the heating and air conditioning system. Check with your dealer before adding equipment to the outside of your vehicle. The left button with the fan symbol regulates the fan speed. The right button is used to change the direction of airflow (upper, bi-level or floor) to the rear seat area. To turn the rear climate controls on or off, press the middle button. The rear control will only turn on if the front is on and is not in defrost mode. 3-25
