UNDERSTANDING YOUR INSTRUMENT PANEL 107 Circulation Control Use this control to choose between outside air intake or recirculation of the air inside the vehicle. Only use the recirculate mode to temporarily block out any outside odors, smoke, or dust and to cool the interior rapidly upon initial start up in very hot or humid weather. This control only operates in the Outside Air and Recirculate modes; there is no in between position. Do not place the control between these positions. NOTE: Continuous use of the recirculate mode may make the inside air stuffy and window fogging may occur. Extended use of this mode is not recommended. In cold weather, the use of the Recirculate position will cause windows to fog on the inside because of moisture build up inside the vehicle. For maximum defogging, select the Outside Air position. If the mode control is in the range between Mix and Defrost and you choose the Recirculate mode, the mode control knob will automatically move to the Mix position. NOTE: If you choose either the Mix or Defrost modes and the Circulation control is in the Recirculate Mode, the system will automatically switch to the Outside Air position. 4
