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 If your vehicle has a 135 inch (343 cm) wheelbase, a 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. 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). The fan knob located on the front climate control panel must be turned to AUX (Auxiliary) to let a rear seat passenger 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 AUX. 9 (Fan): Turn the left knob clockwise or counterclockwise to increase or decrease the fan speed in the rear-seating area. This position turns the system off. 9: 3-23
