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). To change the current mode, select one of the following: H (Vent): Use this mode to direct air to the upper outlets, with a little air directed to the floor outlets. 2(Floor): Use this mode to direct most of the air to the floor outlets. 9 (Fan): Turn the left knob clockwise or counterclockwise to HIGH, MED (Medium) or LOW to increase or decrease the fan speed in the rear-seating area. Turn the knob to OFF to turn off the fan. Temperature Control: To increase or decrease the temperature for the rear of the vehicle, turn the right knob located on the climate-control panel. The air-conditioning system on the main climate control panel must be turned on to direct cooled air to the rear of the vehicle. If it is not on, then the temperature in the rear of the vehicle will remain at cabin temperature. Be sure to keep the area under the front seats clear of any objects so that the air inside of your vehicle can circulate effectively. For information on how to use the main climate control system, see Climate Control System on page 3-17. For information on ventilation, see Outlet Adjustment on page 3-20. 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. 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. Turn the center knob clockwise or counterclockwise to change the direction of the airflow in the rear seating area. 3-22
