Automatic Temperature Control (ATC)
Automatic Operation
1. Push the AUTO button on the faceplate, or the AUTObutton on the touchscreen on the Automatic Temperature
Control (ATC) Panel.
2. Next, adjust the temperature you would like the system to maintain by adjusting the driver and passenger
temperature control buttons. Once the desired tempera -
ture is displayed, the system will achieve and automati -
cally maintain that comfort level.
3. When the system is set up for your comfort level, it is not necessary to change the settings. You will experience the
greatest efficiency by simply allowing the system to func -
tion automatically.
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 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
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. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system 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
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.

Outside Air Intake
Make sure the air intake, located directly in front of the wind-
shield, 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.
Cabin Air Filter
The climate control system filters out dust and pollen from
the air. Contact an authorized dealer to service your cabin air
filter, and to have it replaced when needed. Operating Tips Chart

Power Window ControlsPower Window Switches

The power window controls located on the driver's door trim
panel have up-down switches that give you fingertip control of
all power windows. There is a single opening and closing
switch on the front passenger door for passenger window
control and on the rear doors for rear window control. The
windows will operate when the ignition switch is turned to the ON/RUN or ACC position, and for up to 10 minutes after the
ignition is turned OFF or until a front door is opened.

NOTE:
The Key Off Power Delay feature will allow the power
windows to operate for up to 10 minutes after the ignition is
turned OFF. This feature is cancelled when either front door
is opened.
