NOTE:In cold weather, use of Recirculation mode may
lead to excessive window fogging. The recirculation
feature may be unavailable (button on the touchscreen
greyed out) if conditions exist that could create fogging
on the inside of the windshield. On systems with Manual
Climate Controls, the recirculation mode is not allowed
in Defrost mode to improve window clearing operation.
Recirculation will be disabled automatically if this mode
is selected. Attempting to use Recirculation while in this
mode will cause the LED in the control button on the
faceplate to blink and then turn off.
Automatic Temperature Control (ATC)
Automatic Operation
1. Push the AUTO button on the faceplate or press the
“AUTO” button on the touchscreen.
2. Next, adjust the temperature you would like the
system to maintain by adjusting the driver and pas-
senger temperature buttons on the faceplate or but-
tons on the touchscreen. Once the desired temperature
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 temperature. You will
experience the greatest efficiency by simply allowing
the system to function automatically.
NOTE:
•It is not necessary to move the temperature settings. 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 Uconnect® customer-
programmable feature. Refer to the “Uconnect® Sys-
tem Settings” in this section of the manual.

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. Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for proper coolant selection.
Use of the air Recirculation mode during Winter months is
not recommended because it may cause window fogging.
Vacation/Storage
Any time 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 in high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost on
the inside of the glass in very cold 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.
NOTE:Automatic Temperature Controls (ATC) will au-
tomatically adjust the climate control settings to reduce
or eliminate window fogging on the front windshield.
When this occurs, recirculation will be unavailable.
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, can cause
odor, and if they enter the plenum they could plug the
water drains. In winter months, ensure the air intake is
clear of ice, slush and snow.

STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to save fuel and
reduce emissions. The system will stop the engine auto-
matically during a vehicle stop if the required conditions
are met. Releasing the brake pedal will automatically
re-start the vehicle.
Automatic Mode
The Stop/Start feature is enabled after every normal
customer engine start. It will remain in STOP/START
NOT READY until you drive forward with a vehicle
speed greater than 5 mph (8 km/h). At that time, the
system will go into STOP/START READY and if all other
conditions are met, can go into an STOP/START AUTO
STOP ACTIVE “Autostop” mode.
To Activate The Autostop Mode, The Following Must
Occur:
1.The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in the
Electronic Vehicle Information Center (EVIC)/ Driver
Information Display (DID) within the Stop/Start section.
Refer to “Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID)” in “Understanding
Your Instrument Panel” for further information.
2. The vehicle must be completely stopped.
3. The transmission Gear Selector must be in Drive and
the brake pedal depressed.
The engine will shut down, the tachometer will move to
the zero position and the stop/start telltale will illuminate
indicating you are in an Autostop. While in an Autostop,
the Climate Controls system may automatically adjust
airflow to maintain cabin comfort. Customer settings will
be maintained upon return to an engine running condition.
