UNDERSTANDING YOUR INSTRUMENT PANEL 213 Bi-Level Air flows through the outlets located in the instrument panel and those located on the floor. NOTE: There is a difference in temperature between the upper and lower outlets for added comfort. The warmer air goes to the floor outlets. This feature gives improved comfort during sunny but cool conditions. Heat Outside air flows primarily through the floor outlets located under the instrument panel. Mix Outside air flows in equal proportions through the floor and defroster outlets. Defrost Outside air is primarily directed to the windshield through the defroster outlets located at the base of the windshield and side window demist outlets. NOTE: The air conditioning compressor operates in both Mix and Defrost or a blend of these modes, even if the A/C button has not been pressed. This dehumidifies the air to help dry the windshield. Blower Control The rotary knob on the left of the control panel is the blower control. Turn the knob clockwise to one of the four positions to obtain the blower speed you desire. To turn the blower off, turn the knob to the far left position. 4
