Automatic Temperature Control (ATC)
Automatic Operation
1. Push the AUTO button on the faceplate or press the“AUTO” button on the touchscreen.
2. Adjust the temperature you would like the system to maintain by adjusting the driver and passenger tem-
perature buttons on the faceplate or buttons on the
touchscreen. Once the desired temperature is dis-
played, 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 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 fea-
ture. Refer to the “Uconnect System Settings” in this
section of the manual.
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.
426 UNDERSTANDING YOUR INSTRUMENT PANEL

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, tempera-
ture control will continue to operate automatically.
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.
A solution of 50% OAT (Organic Additive Technology)
coolant that meets the requirements of FCA Material
Standard MS.90032 and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
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 the

touch the parking brake, brake pedal or the gear
selector.
• Do not leave the key fob in or near the vehicle, or
in a location accessible to children, and do not
leave the ignition of a vehicle equipped with
Keyless Enter-N-Go in the ACC or ON/RUN mode.
A child could operate power windows, other con-
trols, or move the vehicle.
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
Automatic Transmission
The gear selector must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.
456 STARTING AND OPERATING

CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
• Shift into PARK only after the vehicle has come to
a complete stop.
• Shift into or out of REVERSE only after the vehicle
has come to a complete stop and the engine is at
idle speed.
• Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
Keyless Enter-N-Go — Ignition
This feature allows the driver to oper-
ate the ignition switch with the push
of a button, as long as the Remote
Start/Keyless Enter-N-Go Key Fob is
in the passenger compartment.

3. The system takes over and attempts to start thevehicle. If the vehicle fails to start, the starter will
disengage automatically after 10 seconds.
4. If you wish to stop the cranking of the engine prior to the engine starting, push the button again.
NOTE: Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.
To Turn Off The Engine Using ENGINE
START/STOP Button
1. Place the gear selector in PARK, then push and release the ENGINE START/STOP button.
2. The ignition switch will return to the OFF position.
3. If the gear selector is not in PARK, the ENGINE START/STOP button must be held for two seconds or
three short pushes in a row with the vehicle speed above 5 mph (8 km/h) before the engine will shut off.
The ignition switch position will remain in the ACC
position until the gear selector is in PARK and the
button is pushed twice to the OFF position. If the gear
selector is not in PARK and the ENGINE START/
STOP button is pushed once, the Driver Information
Display (DID) will display a “Vehicle Not In Park”
message and the engine will remain running. Never
leave a vehicle out of the PARK position, or it could
roll.
NOTE: If the ignition switch is left in the ACC or RUN
(engine not running) position and the transmission is in
PARK, the system will automatically time out after 30
minutes of inactivity and the ignition will switch to the
OFF position.
458 STARTING AND OPERATING

ENGINE START/STOP Button Functions — With
Driver ’s Foot OFF The Brake Pedal (In PARK Or
NEUTRAL Position)
The ENGINE START/STOP button operates similar to an
ignition switch. It has four positions, OFF, ACC, RUN
and START. To change the ignition positions without
starting the vehicle and use the accessories follow these
steps:
•Starting with the ignition in the OFF position,
• Push the ENGINE START/STOP button once to place
the ignition to the ACC position (DID will display
“ACC”),
• Push the ENGINE START/STOP button a second time
to place the ignition to the RUN position (DID will
display “ON/RUN”), •
Push the ENGINE START/STOP button a third time to
return the ignition to the OFF position (DID will
display “OFF”).Extreme Cold Weather (Below –22°F Or 30°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails To Start
WARNING!
• Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
