Rear Air Conditioning and Heating System Your vehicle may have a rear heating and air-conditioning system. This system regulates the temperature, the fan speed and the air delivery for the rear-seat passengers only. It also works with the main climate-control system in your vehicle. Rear Climate-Control Panel The rear control panel for this system is located in the second row behind the driver in the rear of your vehicle. A rear-seat passenger can use this control panel to personally adjust the temperature, the direction of the airflow and the fan speed for the rear-seating area. The fan knob located on the front climate control panel must be turned to REAR CNTL to allow a rear-seat passenger to use the control panel in the rear-seating area. Performing this action disables the front control panel. To return control to this panel, move the fan knob out of REAR CNTL. Front Climate-Control Panel Use this control panel when you would like to maintain a separate temperature setting. Adjust the direction of the airflow or adjust the fan speed for the rear-seat passenger(s). 3-20
