REAR CLIMATE CONTROL OFF
To turn the rear climate controls off, push the
OFF button below the rear climate control
display, or if equipped, press and release the
OFF button on the Rear Comfort And
Convenience Display touchscreen, near the blower
buttons.
AUTOMATIC TEMPERATURE CONTROL
(ATC)
Automatic Operation

1. Push the AUTO button on the front climate control
display, and the word “AUTO” will illuminate along
with two temperatures for the driver and front
passenger. The system will then automatically
regulate the amount of airflow.

2. Adjust the temperature you would like the system to maintain, by adjusting the driver, passenger, and rear
temperatures. 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. The
system automatically adjusts the temperature, mode, and
fan speed to provide comfort as quickly as possible. 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 fan will engage
immediately if the Defrost mode is selected, or by
changing the front blower setting.
Manual Operation Override
This system offers a full complement of manual override
features. The AUTO symbol in the front climate control
display will no longer be illuminated when the system is
being used in the manual mode.
NOTE:The system will not automatically sense the presence of
fog, mist or ice on the windshield. Defrost mode must be
manually selected to clear the windshield and side glass.
CLIMATE VOICE RECOGNITION
Adjust vehicle temperatures hands-free and keep
everyone comfortable while you keep moving ahead (If
vehicle is equipped with climate control).
Push the VR/Phone button . 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 368.
CAUTION!
Interior air enters the Rear Climate Control system
through an intake grille, located in the right side trim
panel behind the third row seats. The heater outlets are
located in the right side trim panel, just behind the rear
doors. Do not block or place objects directly in front of
the inlet grille or heater outlets. The electrical system
could overload causing damage to the blower motor.

Oil Level
The 3.0L engine does not have a
traditional “dipstick” and there is no
need to manually check the oil level
Úpage 316.
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message will
display in the instrument cluster display for five seconds
after a single chime has sounded, to indicate the next
scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate, dependent upon
your personal driving style and environmental conditions.
Unless reset, this message will continue to display each
time the ignition is placed in the ON/RUN position. To turn
off the message temporarily, push and release the OK or
arrow buttons. To reset the oil change indicator system
(after performing the scheduled maintenance), refer to
the following procedure.3

122STARTING AND OPERATING
COLD WEATHER OPERATION
(B
ELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater
(available from an authorized dealer) is recommended.
AFTER STARTING
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
TURBOCHARGER “COOL DOWN” —
3.0L E
NGINE ONLY
The 3.0L engine is equipped with an after-run pump to
cool the turbocharger after the engine is shut off.
Depending on the type of driving and the amount of cargo,
the pump will run for up to 20 minutes after the engine
has been shut off to circulate coolant through the
turbocharger. Although the pump is rubber-mounted for
quiet operation, it is normal to hear it running during this
time.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine. The engine block heater cord is coiled and strapped right
behind the engine air cleaner filter assembly from the
manufacturer.
ENGINE BREAK-IN RECOMMENDATIONS
An initial break-in period is recommended for the
powertrain (engine, transmission, axle, etc.) in your
vehicle. Adhering to the following guidelines will contribute
to improved longevity, fuel economy, and performance.
Drive moderately during the first 100 miles (160 km).
After that, for the first 500 miles (800 km), avoid long
periods at constant speed. Varying speed, engine RPM,
and throttle position is desirable.
Avoid high performance, severe off-road, and towing for
the first 500 miles (800 km).
NOTE:A new engine may consume some oil during its first few
thousand miles (km) of operation. This should be
considered a normal part of the break-in and not inter -
preted as a problem. For engines not equipped with an oil
level sensor, please check your oil level frequently during
the break-in period. Add manufacturer-approved oil as
required
Úpage 376.
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.
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 section of the
Uconnect settings.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result. ONLY USE OILS THAT
ARE API APPROVED

SAFETY289
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 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!
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.

IN CASE OF EMERGENCY303
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be serviced by
an authorized dealer.
Potential signs of vehicle overheating can be:
Temperature gauge is at HOT (H)
 Strong smell of coolant
 White smoke coming from engine or exhaust
 Coolant bottle coolant has bubbles present In the event it is observed that the temperature gauge is
moving towards or close to the HOT (H) position, you can
reduce the potential for overheating by taking the
appropriate action.

On the highways — slow down.
 In city traffic — while stopped, place the transmission in
NEUTRAL (N), but do not increase the engine idle speed
while preventing vehicle motion with the brakes.
 If your Air Conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
 You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control
to high. This allows the heater core to act as a supple -
ment to the radiator and aids in removing heat from the
engine cooling system.
MANUAL PARK RELEASE
To move the vehicle in cases where the transmission will
not shift out of PARK (P) (such as a depleted battery), a
Manual Park Release is available.
WARNING!
 Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
 Never add fuel when the engine is running. This is in
violation of most state and federal fire regulations
and may cause the Malfunction Indicator Light to
turn on.
 A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (H), as
soon as it’s safe, pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until the
pointer drops back into the normal range. If the pointer
remains on HOT (H), and you hear continuous chimes,
turn the engine off immediately and call for service.
WARNING!
You should be seated in the driver’s seat with your foot
firmly placed on the brake pedal to maintain control of
the vehicle before activating the Manual Park Release.
If possible, you should apply the parking brake.
Activating the Manual Park Release will allow your
vehicle to roll away if it is not secured or properly
connected to a tow vehicle. Activating the Manual Park
Release on an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and extended idling will influence
when the “Oil Change Required” message is displayed.
Have your vehicle serviced as soon as possible, within the
next 500 miles (805 km).An authorized dealer will reset the oil change indicator
message after completing the scheduled oil change or for
engine oil life reset procedure Úpage 101.
NOTE:3.0L & 5.7L Engines:
Under no circumstances should oil
change intervals exceed 10,000 miles (16,000 km), or
12 months, whichever comes first. The engine controller
also monitors the number of hours of engine run time, and
will illuminate the oil change indicator after 350 hours
(which is not likely to be exceeded except for certain fleet
customers with extended engine idling periods).
6.4L Engines: Under no circumstances should oil change
intervals exceed 6,000 miles (10,000 km), or 6 months,
whichever comes first. The engine controller also monitors
the number of hours of engine run time, and will illuminate
the oil change indicator after 350 hours (which is not likely
to be exceeded except for certain fleet customers with
extended engine idling periods). Once A Month Or Before A Long Trip:

Check engine oil level
 Check windshield washer fluid level
 Check the tire inflation pressures and look for unusual
wear or damage
 Check the fluid levels of the coolant reservoir, brake
master cylinder and fill as needed.
 Check function of all interior and exterior lights
