Rear Air Vents To maximize airflow through the rear heater outlet, place the left bucket seat in the second row in the forward position. See "Adjusting Rear Seats" in the Index. Ventilation System 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 fan is running. Your vehicle has air outlets that allow you to adjust the direction and amount of airflow inside the vehicle. Push the outlet up or down to change the direction of the air flow. Increase or reduce the amount of airflow by opening and closing the louvers. Opening and closing the louvers will also direct airflow from side to side. The air-flow through the vents can be shut off completely by turning the thumbwheel next to each outlet all the way down. You can also stop outside air from entering the vehicle by turning the fan to OFF and pushing the RECIRCULATION button. The vent behind the left rear seat is the cold air return vent. Be sure to keep it free of obstructions. Keep the area around the base of the center instrument panel console, between and under the front seats, free of objects that could obstruct airflow to the rear. 3-8
