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 that 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
temperature.
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 US or Metric units
by selecting the US/Metric customer-programmable
feature within Uconnect Settings
Úpage 191.
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 being used in the manual
mode.
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 387.
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 air distribution box, 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.

Certain video game consoles exceed this power limit, as
will most power tools.

Center Console Power Inverter Outlet

There is also a second 115 Volt (400 Watts maximum)
power inverter located on the rear of the center console.
This inverter can power cellular phones, electronics and
other low power devices requiring power up to 400 Watts. Certain video game consoles exceed this power limit, as
will most power tools.
All power inverters are designed with built-in overload
protection. If the power rating of 400 Watts is exceeded,
the power inverter shuts down. Once the electrical device
has been removed from the outlet the inverter should
reset.

Rear Center Console Power Inverter Outlet

NOTE:
400 Watts is the maximum for the inverter, not each
outlet. If three outlets are in use, 400 Watts is shared
amongst the devices plugged in.
If equipped with a front bench seat, there may be a
115 Volt (400 Watts maximum) inverter located to the
right of the center stack, just below the climate controls.
This inverter can power cellular phones, electronics and
other low power devices requiring power up to 400 Watts.
WARNING!
To avoid serious injury or death:
 Only devices designed for use in this type of outlet
should be inserted into any 12 Volt outlet.
 Do not touch with wet hands.
 Close the lid when not in use and while driving the
vehicle.
 If this outlet is mishandled, it may cause an electric
shock and failure.
CAUTION!
Many accessories that can be plugged in draw power
from the vehicle's battery, even when not in use
(i.e., cellular phones, etc.). Eventually, if plugged in
long enough, the vehicle's battery will discharge suffi -
ciently to degrade battery life and/or prevent the
engine from starting.
 Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these intermit -
tently and with greater caution.
 After the use of high power draw accessories, or long
periods of the vehicle not being started (with acces -
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the generator to
recharge the vehicle's battery.
CAUTION!

142STARTING AND OPERATING
To Activate The Autostop Mode, The Following Must Occur:

1. The system must be in STOP/START READY state. A
STOP/START READY message is displayed in the
instrument cluster within the Stop/Start section

Ú
page 98.

2. The vehicle must be decelerating and likely coming to a complete stop.
3. The transmission gear selector must be in DRIVE and the brake pedal pressed.
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.
POSSIBLE REASONS THE ENGINE DOES
N
OT 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 accept -
able cabin temperature has not been achieved 
HVAC is set to full defrost mode at a high blower speed
 Engine has not reached normal operating temperature
 Engine or exhaust temperature is too high
 The battery is charging
 The transmission is not in DRIVE
 Hood is open
 Transfer case is in 4WD LOW

SAFETY313
(Continued)
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel or brake fluid leaks are
suspected, the cause should be located and corrected
immediately.
EXHAUST GAS
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have an authorized dealer inspect the complete
exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO), follow
these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to move your
vehicle in or out of the area.
If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation mode.
 If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed.
WARNING!
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
 Guard against carbon monoxide with proper mainte -
nance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi -
tions repaired promptly. Until repaired, drive with all
side windows fully open.

SERVICING AND MAINTENANCE387
The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
TRACTION GRADES
The Traction grades, from highest to
lowest, are AA, A, B, and C. These grades
represent the tire's ability to stop on wet
pavement, as measured under
controlled conditions on specified
government test surfaces of asphalt and
concrete. A tire marked C may have poor
traction performance.
TEMPERATURE GRADES
The Temperature grades are A (the
highest), B, and C, representing the tire's
resistance to the generation of heat and
its ability to dissipate heat, when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance, which all
passenger vehicle tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A
represent higher levels of performance
on the laboratory test wheel, than the
minimum required by law.
STORING THE VEHICLE
If you are storing your vehicle for more than three weeks,
we recommend that you take the following steps to
minimize the drain on your vehicle's battery:
Disconnect the negative cable from battery.
 Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air condi -
tioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the
possibility of compressor damage when the system
is started again.
WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or peak
traction characteristics.
WARNING!
The temperature grade for this tire is established for a
tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive loading,
either separately or in combination, can cause heat
buildup and possible tire failure.
