²To prevent humidity buildup inside the vehicle, don't drive with the
climate control system in the OFF position.
²Don't put objects under the front seat that will interfere with the
airflow to the back seats.
²Remove any snow, ice or leaves
from the air intake area (at the
bottom of the windshield).
²If your vehicle has been parked with the windows closed during hot
weather, the air conditioner will do a much faster job of cooling if you
drive for two or three minutes with the windows open. This will force
most of the hot, stale air out of the vehicle. Then operate your air
conditioner as you would normally.
²When placing objects on top of your instrument panel, be careful to
not place them over the defroster outlets. These objects can block
airflow and reduce your ability to see through your windshield. Also,
avoid placing small objects on top of your instrument panel. These
objects can fall down into the defroster outlets and block airflow and
possibly damage your climate control system.
Auxiliary heater and air conditioner (if equipped)
If your vehicle is equipped with a factory installed auxiliary unit, the
front control panel will include separate controls for the front and rear
fans.
In addition an auxiliary unit fan
control is located in the headliner at
a location between the front and
rear seats.

²To control the auxiliary fan with
this control, the rear fan switch
on the front control unit must be
in the rear control position.
²The auxiliary unit does not
provide for mixing of hot and
cold air. Adjustment of
temperature in the rear may be
accomplished by increasing or
decreasing the rear fan speed.
AUXILIARY POWER POINT
The auxiliary power point is located
on the instrument panel.
Do not plug optional electrical
accessories into the cigarette lighter.
