Ventilation System For mild outside temperatures when little heating or cooling is needed, use outside air to direct outside air through your vehicle. Air will flow through the instrument panel outlets. Your vehicle's ventilation system supplies outside air to the inside of your vehicle when it is moving. With the side windows closed, air will flow into the front air inlet grilles, through the vehicle, and out of the air exhaust valves. Outside air will also enter the vehicle when the heater or the air conditioning fan is running, unless you have the recirculation button pressed in. For more information on the recirculation button, see "Air Conditioning" earlier in this section. Your vehicle has air outlets in the center and on the sides of the instrument panel. You can move the outlets from side-to-side or up and down to direct the flow of air. The driver's and passenger's side outlets have shut-off thumbwheels. Turn the thumbwheels to the left to shut off air flow or to the right to allow air flow. When you close an outlet, it will increase the flow of air coming out of any outlets that are open. The center outlet does not completely shut off airflow. Your vehicle also has outlets located on the headliner for the rear seat passengers. To use these vents, press on the individual slats to open the vent. Turn the entire vent in the direction you want to direct airflow. Push the slats to close them and block airflow. 3-9
