Controls and Features Climate control knobs (heater only) To turn your heater system on, select any position except OFF. This turns the fan on and allows airflow into the vehicle. To turn your heater off, select OFF. Temperature selection The temperature control 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. H Fan speed adjustment The H (left) knob on the control is the fan control knob which controls the volume of airflow. Rotate the H knob to the right to increase fan speed and increase the amount of air entering the vehicle. Four fan speed positons are available and are indicated by dots beside the H control knob. The largest dot is high speed position. 69
