AUTOMATIC TEMPERATURE CONTROL
(ATC)
Automatic Operation

1. Push the AUTO button on the faceplate, or the
AUTO button 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 temperature is displayed, the
system will achieve and automatically
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
function 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 U.S./Metric within
Uconnect Settings Ú page 199.
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

CLIMATE VOICE RECOGNITION —
I
F EQUIPPED
Adjust vehicle temperatures hands-free and keep
everyone comfortable while you keep moving
ahead. Push the VR button on the steering wheel. After the
beep, say one of the following commands:
“
Set driver temperature to 70 degrees ”
“Set passenger temperature to 70 degrees ”
Did you know: Voice Command for Climate may
only be used to adjust the interior temperature of
your vehicle. Voice Command will not work to
adjust the heated seats or steering wheel if
equipped.
OPERATING TIPS
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
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 Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.

Vacation/Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Úpage 407.
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.
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.
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.
