252 UNDERSTANDING YOUR INSTRUMENT PANEL • Extended use of recirculation may cause the windows to fog. If the interior of the windows begin to fog, press the recirculation button to return to outside air. Some temp/humidity conditions will cause captured interior air to condense on windows and hamper visibility. For this reason, the system will not allow recirculation to be selected while in Defrost or Defrost/Floor mode. Attempting to use the recirculation while in these modes will cause the indicator in the control button to blink and then turn off. Manual Operation This system offers a full complement of manual override features, which consist of blower preferred automatic, mode preferred automatic, or blower and mode preferred automatic. This means the operator can override the blower, the mode, or both. There is a manual blower range for times when the AUTO setting is not desired. The blower can be set to any fixed blower speed by rotating the blower control knob (on the left). NOTE: Please read the automatic temperature control operation chart that follows for details.
