Rear Blower Control
The rear blower control can be manually set to
off, or any fixed blower speed by pushing the
blower control buttons. This allows the rear seat
occupants to control the volume of air circu-
lated in the rear of the vehicle. Turn the control
knob to increase or decrease the fan speed.
CAUTION!
Interior air enters the Rear Automatic Tem-
perature Control System through an intake
grille, located in the right side trim panel
behind the third row seats. The heater outlets
are located in the right side trim panel, just
behind the sliding door . Do not block or place
objects directly in front of the inlet grille or
heater outlets. The electrical system could
overload causing damage to the blower mo-
tor.
Rear Temperature Control
To change the temperature in the rear of the
vehicle, push the temperature buttons. The rear
temperature settings are displayed in the rear
ATC panel.
When rear controls are locked by the front sys-
tem, the Rear Temperature Lock symbol on the
ATC panel is illuminated and any rear overhead
adjustments are ignored.
When the Sync feature is active, the rear tem-
perature is synchronized to the driver’ s tempera-
ture setting. If the rear temperature is changed,
the Sync feature will deactivate.
Operating Tips
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to provide
proper corrosion protection and to protect
against engine overheating. A solution of 50%
OAT (Organic Additive Technology) coolant that
meets the requirements of FCA Material Stan-
dard MS.90032 and 50% water is recom-
mended. Refer to “Fluids and Lubricants” in
“Technical Specifications” for proper coolant
selection.
Winter Operation
Use of the Air Recirculation mode during winter
months is not recommended because it may
cause window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes, in fresh air with the blower setting
on high. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be
quickly removed by turning the mode selector to
Defrost. The Defrost/Floor mode can be used to
maintain a clear windshield and provide suffi-
cient heating. If side window fogging becomes
objectionable, increase blower speed to improve
airflow and clearing of the side windows. Vehicle
windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:
Recirculate without A/C should not be used for
long periods, as fogging may occur.
