disabled automatically if this mode is selected.
Attempting to use Recirculation while in this
mode causes the LED in the control button to

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) coolant that
meets the requirements of FCA Material
Standard MS.90032 and 50% water is
recommended. 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
Any time 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 the fresh air and high blower
setting. This will ensure adequate system
lubrication 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
sufficient heating. If side window fogging
becomes a problem increase blower speed.
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.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstructions
such as leaves. Leaves collected in the air
intake may reduce airflow, and if they enter the
plenum, they could plug the water drains. In
winter months, make sure the air intake is clear
of ice, slush, and snow.
CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
Use care when washing the inside of the
rear window. Do not use abrasive window
cleaners on the interior surface of the
window. Use a soft cloth and a mild
washing solution, wiping parallel to the
heating elements. Labels can be peeled off
after soaking with warm water.
Do not use scrapers, sharp instruments, or
abrasive window cleaners on the interior
surface of the window.
Keep all objects a safe distance from the
window.
