To turn your air conditioner and heater off, select OFF. This will turn the fan off and stop airflow from coming into the vehicle. Temperature selection The Temperature knob is the rotating knob located at the center of the control with tapered RED and BLUE bands surrounding most of the knob. The wide RED part of the band (full right) is the heat or warmer area. The wide BLUE area (full left) is the cool or unheated temperature area. Any position selected between full right and full left will give a temperature between the two extreme temperatures. The cool temperature you select will not be cooler than the outside temperature, unless an A/C mode is selected (if equipped). H Fan speed adjustment The H knob on the control is the fan speed knob which controls the volume of air flow. Rotate the H knob to the right to increase the amount of air entering the vehicle. Four fan speed positions are available and are indicated by LO, two separate dots and HI beside the H control knob. The HI position provides the most air flow. 59
