Air Conditioner and Heater (If equipped) The control for your air conditioner and heater system is located near the center of the instrument panel and operates only when the ignition key is turned to the ON position. Your air conditioner and heater heats or cools your vehicle interior depending on the function and the temperature you select. The right knob is the SELECT knob which allows you to select heating or cooling and determine where the air will be directed. The TEMP knob setting determines the temperature of the air that flows into the vehicle. Climate control knobs To turn your air conditioner and heater system on, rotate the SELECT knob to any position except OFF. This will turn the fan on and allows airflow into the vehicle. Temperature selection The TEMP 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 area. The wide blue area (full left) is the cooling temperature area. Any position selected between full right and full left will give a temperature between the two extremes except in MAX A/C. 62
