Recirculation
When outside air contains smoke, odors, or high humidity,
or if rapid cooling is desired, you may wish to recirculate
interior air by pressing the recirculation control button. The
recirculation indicator will illuminate when this button is
selected. Press the button a second time to turn off the
Recirculation mode and allow outside air into the vehicle.
NOTE: In cold weather, use of recirculation mode may lead
to excessive window fogging. On systems with Manual
Climate Controls, the recirculation mode is not allowed in
Defrost mode to improve window clearing operation.
Recirculation will be disabled automatically if this mode is
selected. Attempting to use recirculation while in this
mode will cause the LED in the control button to blink and
then turn off.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
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) cool-
ant that meets the requirements of FCA Material Standard
MS.90032 and 50% water is recommended. Refer to “Dealer
Service” in “Servicing And Maintenance” for proper cool-
ant selection.
Winter Operation
Use of the air Recirculation mode during winter months is
not recommended because it may cause window fogging.
Vacation Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh air
and high blower setting. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age 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 sufficient heating. If side window fogging be-
comes a problem increase blower speed. Vehicle windows
tend to fog on the inside in mild but rainy or humid
weather.
