AUTOMATIC TEMPERATURE CONTROL
(ATC) — I
F 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 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 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 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 U.S. or Metric
units by selecting the US/Metric customer-program -
mable feature within the Uconnect system
Úpage 126.
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 COMMANDS
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 the driver temperature to 70 degrees ”
 “Set the 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 250.
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.
Stop/Start System — If Equipped
While in an Autostop, the Climate Control system may
automatically adjust airflow to maintain cabin comfort.
Customer settings will be maintained upon return to an
engine running condition.

GETTING TO KNOW YOUR VEHICLE59
There are pinch sensors attached to the side of the lift -
gate opening. Light pressure anywhere along these
strips will cause the liftgate to return to the open posi -
tion.
 If the power liftgate encounters multiple obstructions
within the same cycle, the system will automatically
stop. If this occurs, the liftgate must be operated manu -
ally.
 The power liftgate will release, but not power open, in
temperatures below −12°F (−24°C). Be sure to
remove any buildup of snow or ice from the liftgate
before opening the liftgate.
 If the liftgate is left open for an extended period of time,
the liftgate may need to be closed manually to reset
power liftgate functionality.
Gas props support the liftgate in the open position.
However, because the gas pressure drops with
temperature, it may be necessary to assist the props when
opening the liftgate in cold weather.NOTE:Allow the power system to open the liftgate. Manually
pushing or pulling the liftgate may activate the liftgate
obstacle detection feature and stop the power operation
or reverse its direction.
CARGO AREA FEATURES
Cargo Load Floor
The cargo load floor system has a load capacity of 300 lb
(136 kg).
To provide additional storage area, each rear seat can be
folded flat. This allows for extended cargo space and still
maintains some rear seating room
Úpage 28.
Cargo Tie-Down Hooks And Loops
The tie-downs located on the cargo area floor should be
used to secure loads safely when the vehicle is moving.
Cargo tie-down loops are located on the trim panels.
WARNING!
 Driving with the liftgate open can allow poisonous
exhaust gases into your vehicle. You and your
passengers could be injured by these fumes. Keep
the liftgate closed when you are operating the
vehicle.
 If you are required to drive with the liftgate 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.
WARNING!
During power operation, personal injury or cargo
damage may occur. Ensure the liftgate travel path is
clear. Make sure the liftgate is closed and latched
before driving away.
WARNING!
Cargo tie-downs are not safe anchors for a child seat
tether strap. In a sudden stop or accident, a tie-down
could pull loose and allow the child seat to come
loose. A child could be badly injured. Use only the
anchors provided for child seat tethers.
 To help protect against personal injury, passengers
should not be seated in the rear cargo area. The rear
cargo space is intended for load carrying purposes
only, not for passengers, who should sit in seats and
use seat belts.
The weight and position of cargo and passengers can
change the vehicle center of gravity and vehicle
handling. To avoid loss of control resulting in personal
injury, follow these guidelines for loading your vehicle:
 Do not carry loads that exceed the load limits
described on the label attached to the left door or left
door center pillar.
 Always place cargo evenly on the cargo floor. Put
heavier objects as low and as far forward as possible.
 Place as much cargo as possible in front of the rear
axle. Too much weight or improperly placed weight
over or behind the rear axle can cause the vehicle to
sway.
 Do not pile luggage or cargo higher than the top of
the seatback. This could impair visibility or become a
dangerous projectile in a sudden stop or accident.

78STARTING AND OPERATING
(Continued)
IF ENGINE FAILS TO START
If the engine fails to start after you have followed the
“Normal Starting” procedure and the vehicle has not
experienced an Extended Park condition as previously
defined, it may be flooded. Push the accelerator pedal all
the way to the floor and hold it there while the engine is
cranking. This should clear any excess fuel in case the
engine is flooded. The starter motor will engage
automatically, run for 10 seconds, and then disengage.
Once this occurs, release the accelerator pedal and the
brake pedal, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.AFTER STARTING
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
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
detrimental 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
recommended viscosity and quality grades see
Úpage 256.
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 inter -
preted as a problem.
PARKING BRAKE
ELECTRIC PARK BRAKE (EPB)
Your vehicle is equipped with an 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 parking brake is applied. Also,
be certain to leave the transmission in PARK (P).
You can engage the parking brake in two ways:
 Manually, by applying the EPB switch.
 Automatically, by enabling the Auto Park Brake feature
in the customer programmable features
Úpage 132.
The EPB switch is located in the center console, behind
the gear selector.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a time. Wait
10 to 15 seconds before trying again.
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.
 Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans -
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
 If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type of
start can be dangerous if done improperly
Úpage 200.
WARNING!CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.

188SAFETY
PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the lug nut/bolt torque for tightness. Check the
tires (including spare) for proper cold inflation pressure.
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 the 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

If the vehicle carpet has been removed and
re-installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
 It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
WARNING!
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!
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 MAINTENANCE249
DEPARTMENT OF TRANSPORTATION
UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform
to Federal safety requirements in
addition to these grades.
TREADWEAR
The Treadwear grade is a comparative
rating, based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one and one-half times as well on
the government course as a tire graded
100. 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.
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.8
