Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator to
manually activate or deactivate the air conditioning system.
When the air conditioning system is turned on, cool dehu-
midified air will flow through the outlets into the cabin. Forimproved fuel economy, press the A/C button to turn off the
air conditioning and manually adjust the blower and airflow
mode settings. Also, make sure to select only Panel, Bi-Level,
or Floor modes.
Floor Mode
Floor Mode
Air comes from the floor outlets. A slight amount of air is directed through the defrost and side
window demister outlets.
Mix Mode Mix Mode
Air is directed through the floor, defrost, and side window demister outlets. This setting works best in
cold or snowy conditions that require extra heat to the windshield. This setting is good for
maintaining comfort while reducing moisture on the windshield.
Climate Control OFF Button
This button turns the Climate Control System off.

NOTE:
• On vehicles equipped with a 12-inch display, reducing theblower control all the way down will turn the climate off.
• For Manual Climate Controls, if the system is in Mix, Floor or Defrost Mode, the A/C can be turned off, but the A/C
system shall remain active to prevent fogging of the
windows.
• If fog or mist appears on the windshield or side glass, select Defrost mode, and increase blower speed if needed.
• If your air conditioning performance seems lower than expected, check the front of the A/C condenser (located in
front of the radiator), for an accumulation of dirt or insects.
Clean with a gentle water spray from the front of the radi -
ator and through the condenser.
MAX A/C
MAX A/C sets the control for maximum cooling perfor -
mance.
Press and release to toggle between MAX A/C and the prior
settings. The button illuminates when MAX A/C is on.
In MAX A/C, the blower level and mode position can be
adjusted to desired user settings. Pressing other settings will
cause the MAX A/C operation to switch to the selected
setting and MAX A/C to exit. Recirculation
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 condi
-
tions exist that could create fogging on the inside of the
windshield.
Automatic Temperature Control (ATC) — If Equipped
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 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.

STARTING AND OPERATING 297
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. For the recom -
mended viscosity and quality grades, refer to “Fluids And
Lubricants” in “Technical Specifications”. NOTE:
A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered a normal part of the break-in and not interpreted
as a problem. Please check your oil level with the engine oil
indicator often during the break in period. Add oil as
required.
PARKING BRAKE
Electric Park Brake (EPB)
Your vehicle is equipped with an Electric Park Brake System
(EPB) that offers simple operation, and some additional
features that make the parking brake more convenient and
useful.
The parking brake is primarily intended to prevent the
vehicle from rolling while parked. Before leaving the vehicle,
make sure that the park brake is applied. Also, be certain to
leave the transmission in PARK.
You can engage the park brake in two ways:
• Manually, by applying the park brake switch.
• Automatically, by enabling the Auto Park Brake feature in
the customer programmable features section of the Ucon -
nect settings.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.5

334 STARTING AND OPERATING
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to save fuel and reduce
emissions. The system will stop the engine automatically
during a vehicle stop if the required conditions are met.
Releasing the brake pedal or shifting out of DRIVE will auto-
matically restart the engine.
Vehicles equipped with eTorque contain a heavy duty motor
generator and an additional hybrid electric battery to store
energy from vehicle deceleration for use on engine startup
after a stop as well as providing launch torque assist.
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 2 mph (3 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 instrument cluster within the Stop/Start section. Refer to
“Instrument Cluster Display” in “Getting To know 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 indi -
cating 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 main -
tained upon return to an engine running condition.
Possible Reasons The Engine Does Not Autostop
Prior to engine shut down, the system will check many safety
and comfort conditions to see if they are fulfilled. In
following situations, the engine will not Autostop:
• Driver’s seat belt is not buckled
• Driver’s door is not closed
• The vehicle is on a steep grade
• Cabin heating or cooling is in process and an acceptable cabin temperature has not been achieved
