Your vehicle also has the flow-through ventilation system described later in this section. Mode Knob The right knob changes the functions of the system. The available modes are the following: (Vent): In this position most of the airflow comes through the instrument panel outlets. A small amount of air comes through the floor outlets. Set the center knob to the desired temperature for comfort. (Bi-Level): In this position the airflow comes through the instrument panel outlets and through the floor outlets. Set the center knob to the desired temperature. (Floor): In this position most of the airflow comes through the floor outlets. The rest of the air comes through the windshield and side window vents. Set the center knob to the desired temperature for comfort. (Defog): This position divides the airflow between the floor outlets and the windshield defroster vent. The air conditioning compressor will run automatically in this position when it is needed to help dry the air in the vehicle.
