GETTING TO KNOW YOUR VEHICLE 71
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” for further information.
To provide you with maximum comfort in the
Automatic mode during cold start-ups, the blower
fan remains 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
NOTE:
Refer to the chart at the end of this section for
su
ggested 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. OAT coolant
(conforming to MS.90032) is recommended.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for proper coolant selection.
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. Refer to “Fluids And Lubricants” in
“Technical Specifications” for proper coolant
selection. 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 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 interior
surface of the window.
Keep all objects a safe distance from the
window.
