systems. With any of these systems, the rear climate

outlets is determined by the front passenger’s
temperature setting. Press the PWR button to turn the
rear climate controls on and off. Use the mode knob
to change the direction of airow (upper, bi-level or oor)
to the rear seat area.If your vehicle has the rear seat audio system, the lower
buttons are used to adjust the rear seat climate controls.
The temperature of the air coming through the rear
outlets is determined by the front passenger’s
temperature setting.
If the front climate control is on and not in defrost mode,
the rear climate control can be enabled by pressing
the lower power button (center button) on the control
face. If the front is off or is in defrost mode, the

button. The mode button, on the right, controls where
