GETTING TO KNOW YOUR VEHICLE
44
NOTE:

It is not necessary to move the tempera -
ture settings for cold or hot vehicles. The
system automatically adjusts the tempera
-
ture, mode, and blower speed to provide
comfort as quickly as possible.

The temperature can be displayed in U.S.
or Metric units by selecting the US/Metric
customer-programmable feature. Refer to
the “Uconnect Settings” in “Multimedia”
in your Owner’s Manual for further infor
-
mation.
To provide you with maximum comfort in the
Automatic mode during cold start-ups, the
blower fan will remain on low until the
engine warms up. The blower will increase in
speed and transition into Auto mode.
Manual Operation Override
This system offers a full complement of
manual override features. The AUTO symbol
in the front ATC display will be turned off
when the system is being used in the manual
mode.
Operating Tips
Summer Operation
The engine cooling system must be
protected with a high-quality antifreeze
coolant to provide proper corrosion protec
-
tion and to protect against engine over -
heating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and
defroster performance, make sure the engine
cooling system is functioning properly and
the proper amount, type, and concentration
of coolant is used. Use of the Air Recircula
-
tion 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 lubrication to minimize the
possibility of compressor damage when the
system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in
mild, rainy, and/or humid weather. To clear
the windows, select Defrost or Mix mode and
increase the front blower speed. Do not use
the Recirculation mode without A/C for long
periods, as fogging may occur.
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 inte
-
rior surface of the window.

Keep all objects a safe distance from the
window.
