Rear Air Conditioning and Rear Heater 
(If Equipped)

If your vehicle has the rear air conditioning and rear
heater system combination, controls are provided to
regulate temperature, location and fan speed.

Front Control

To adjust the airflow speed, turn the fan knob located on
the left side to the desired setting.

To activate the second seat control system, turn the fan
knob on the front overhead control to REAR.

To regulate the airflow location, adjust the right knob on
the control panel. Turn the knob clockwise for floor vent
airflow or counterclockwise for headliner vent airflow.
Generally, the instrument panel outlets are used for air
conditioning and the floor vents for heating. The knob
can be set to any blend setting.

To adjust the air temperature, turn the temperature knob
on the center of the control panel.

For warmer air, turn the knob clockwise toward red. For
cooler air, turn the knob counterclockwise toward blue.

Rear Control

The rear control works just like the front control. It
allows second seat passengers to adjust the controls as
they desire. To use the rear control, first turn the knob
on the front control panel to REAR.
