Ventilation System L Ventilation Tips 0 For mild outside temperatures when little heating or cooling is needed, use VENT to direct outside air through your vehicle. 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 far better, reducing the chance of fogging the inside of your windows. 0 Adjust the direction of airflow by moving the louvered vents. Your vehicle's flow-through ventilation system supplies outside air into the vehicle when it is moving. Outside air will also enter the vehicle when the air conditioning fan is running. When you enter a vehicle in cold weather, set the mode to FLOOR and the fan to the highest speed for a few moments before driving off. This helps clear the intake ducts of snow and moisture and reduces 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. 0 Defogging and Defrosting Your system has two settings for clearing the front and side windows. To defrost the windows quickly, use DEFROST with the temperature knob(s) all the way in the red area. To warm passengers while keeping the windows clean, use DEFOG. 3-5
