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.
Use this control panel when you would like to maintain
a separate temperature setting. Adjust the direction
of the airow or adjust the fan speed for the rear-seat
passenger(s).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
airow 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 airow in the
rear-seating area. Front Climate-Control Panel
