system, it maintains the temperature, fan speed and air
delivery for the rear-seat passengers only. It also
works with the main climate-control system in the
vehicle.
Use this control panel to maintain a separate
temperature setting. Adjust the direction of the airflow or
adjust the fan speed for the rear seat passenger(s).

can be adjusted for the rear seating area by a rear seat
passenger.
