Rear Air Conditioning and Rear Heater 
(If Equipped)
If your vehicle has a rear air conditioning and rear
heater system combination, controls are provided 
to regulate the temperature, location and speed of 
the airflow.
Front Passenger Control
To adjust the air temperature, turn the temperature knob
on the right side of the control panel.
For warmer air, turn the knob toward the red area, and
for cooler air, turn the knob toward the blue area.
To regulate the airflow location, adjust the center knob
on the control panel. Turn the knob counterclockwise
for floor vent airflow or clockwise for headliner vent air
flow. Generally, the upper vents are used for air
conditioning and the floor vents for heating. The control
knob can be set to any blend setting.
To adjust the airflow speed, turn the fan knob on the left
side of the control panel to the desired fan speed.
To activate the rear control, turn the fan knob on the
front control to REAR CNTL.
