when this feature is enabled. Sync is used to synchronize
the passenger temperature setting with the driver tem-
perature setting. Changing the passenger temperature
setting while in Sync will automatically exit this feature.
10. Blower Control
Blower control is used to regulate the amount of air
forced through the climate system. There are seven
blower speeds available. Adjusting the blower will cause
automatic mode to switch to manual operation. The
speeds can be selected using either Buttons on the
faceplate or buttons on the touchscreen as follows:
Blower Control Knob On The Faceplate
The blower speed increases as you turn the control
clockwise from the lowest blower setting. The blower
speed decreases as you turn the blower control knob
counterclockwise.
Button On The Touchscreen
Use the small blower icon to reduce the blower setting
and the large blower icon to increase the blower setting.
Blower can also be selected by pressing the blower bar
area between the icons.
11. Modes
The airflow distribution mode can be adjusted so air
comes from the instrument panel outlets, floor outlets,
demist outlets and defrost outlets. The Mode settings are
as follows:
•Panel Mode
Air comes from the outlets in the instrument
panel. Each of these outlets can be individually
adjusted to direct the flow of air. The air vanes of the
center outlets and outboard outlets can be moved up and
down or side to side to regulate airflow direction. There
is a shut off wheel located below the air vanes to shut off
or adjust the amount of airflow from these outlets.

temperature settings or on the touchscreen, press and
slide the temperature bar towards the red arrow for
warmer temperature settings.
NOTE:In Sync mode, this button will also automatically
adjust the passenger temperature setting at the same
time.
15. Temperature Control (Uconnect® 5.0)
Press the temperature button on the touchscreen to regu-
late the temperature of the air inside the passenger com-
partment. Moving the temperature bar into the red area,
indicates warmer temperatures. Moving the temperature
bar into the blue area indicates cooler temperatures.
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 dehumidified air will flow through the outlets into
the cabin. For improved 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.
NOTE:
•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 adjust blower speed if
needed.
•If your air conditioning performance seems lower than
expected, check the front of the A/C condenser (lo-
cated in front of the radiator), for an accumulation of
dirt or insects. Clean with a gentle water spray from

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
The system allows for manual selection of blower speed,
air distribution mode, A/C status and recirculation control.
The blower fan speed can be set to any fixed speed by
adjusting the blower control. The fan will now operate at
a fixed speed until additional speeds are selected. This
allows the front occupants to control the volume of air
circulated in the vehicle and cancel the Auto mode.
The operator can also select the direction of the airflow
by selecting one of the available mode settings. A/C
operation and Recirculation control can also be manually
selected in Manual operation.
NOTE:Each of these features operates independently
from each other. If any feature is controlled manually,
temperature control will continue to operate automati-
cally.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
OAT coolant (conforming to MS-12106) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.

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.
