Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.
Adding outside equipment to the front of your
vehicle, such as hood-air deflectors, may affect the
performance of the heating and air conditioning
system. Check with your dealer before adding
equipment to the outside of your vehicle.
Rear Air Conditioning System
If your vehicle is equipped with the optional rear air
conditioner it has two rear air conditioning fan speed
selectors. One fan speed selector is located in the
overhead console and the other is located in the
headliner above the second row seats.
To increase and decrease the flow of cooled air to the
rear vents, turn the knob to the fan speed you want.
The knob has three speed positions. To increase
the flow of cooled air, turn the knob clockwise. To
decrease the flow of cooled air, turn it counterclockwise.
To turn the fan off, turn the knob to the off position.
To operate the rear system using the front control, just
turn the knob to the fan position you want.
To use the rear control, first turn the front control to the
AUX position. Then, the rear control can be used to
increase and decrease the airflow.
