NOTE:
• It is not necessary to move the temperature
settings for cold or hot vehicles. The system
automatically adjusts the temperature, 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 information.
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 protection and to protect
against engine overheating. OAT coolant (con-
forming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling sys-
tem is functioning properly and the proper
amount, type, and concentration of coolant is
used. 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
V ehicle windows tend to fog on the inside in
mild, rainy, and/or humid weather . To clear the
windows, select Defrost or Mix mode and in-
crease the front blower speed. Do not use the
Recirculation mode without A/C for long peri-
ods, 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 wash-
ing solution, wiping parallel to the heat-
ing 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.
