Mode selection
The mode selection dial controls the direction of airflow through the ventilation system.

Bi-level (B, C, D)
Airflow is directed toward the face and the floor.

Most of the airflow is directed to the floor and windshield, and a small portion to the side window defrosters.
Defrost Level (A, C)
