POWER INVERTER — IF EQUIPPED
There is a 115 Volt, 150 W inverter outlet located
on the back of the center console to convert DC
current to AC current. This outlet can power cellular
phones, electronics and other low power devices
requiring power up to 150 W. Certain video game
consoles exceed this power limit, as will most
power tools.
Power Inverter

The power inverter is designed with built-in
overload protection. If the power rating of 150 W is
exceeded, the power inverter automatically shuts
down. Once the electrical device has been
removed from the outlet the inverter should
automatically reset. To avoid overloading the
circuit, check the power ratings on electrical
devices prior to using the inverter.
WIRELESS CHARGING PAD —
I
F EQUIPPED

Wireless Charging Pad

Your vehicle may be equipped with a 15 W3 Amp
Qi wireless charging pad located inside of the
storage area below the climate controls. This
charging pad is designed to wirelessly charge your
Qi enabled mobile phone. Qi is a standard that
allows wireless charging of your mobile phone.
Your mobile phone must be designed for Qi
wireless charging. If the phone is not equipped
with Qi wireless charging functionality, an
aftermarket sleeve or a specialized back plate can
be purchased from your mobile phone provider or
a local electronics retailer. Please see your
phone’s owner’s manual for further information.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.) will
degrade the battery even more quickly. Only
use these intermittently and with greater
caution.
After the use of high power draw accessories,
or long periods of the vehicle not being started
(with accessories still plugged in), the vehicle
must be driven a sufficient length of time to
allow the generator to recharge the vehicle's
battery.
CAUTION!
WARNING!
To avoid serious injury or death:
Do not insert any objects into the receptacles.
Do not touch with wet hands.
Close the lid when not in use.

NOTE:
Opening or closing the Hands-Free Liftgate
requires a valid Passive Entry key fob within 5 ft
(1.5 m) of the liftgate handle. If a valid Passive
Entry key fob is not within 5 ft (1.5 m), the lift -
gate will not respond to any kicks.
The Hands-Free Liftgate feature may be turned
on or off through the Uconnect system
Ú page 204.
The Hands-Free Liftgate feature should be
turned off during jacking, tire changing, manual
car wash, and vehicle service.
The Hands-Free Liftgate feature can be acti -
vated by any metallic object making a similar
in-and-out motion under the rear fascia/
bumper, such as cleaning using a metal broom.
The Hands-Free Liftgate will only operate when
the transmission is in PARK.
If anything obstructs the Hands-Free Liftgate
while it is opening or closing, the liftgate will
automatically reverse to the closed/open posi -
tion, provided it meets sufficient resistance.
There are pinch sensors attached to the side of
the liftgate opening. Light pressure anywhere
along these strips will cause the liftgate to
return to the open position.
If the power liftgate encounters multiple
obstructions within the same cycle, the system
will automatically stop. If this occurs, the liftgate
must be operated manually.
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 (approximately one hour), 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 Storage
The load floor is designed for a maximum load of
300 lb (136 kg).
If equipped, there may be a removable storage bin
located on the left side of the rear cargo area.
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.

122STARTING AND OPERATING
4. If the engine fails to start after eight attempts, allow the starter to cool for at least
10 minutes, then repeat the Extended Park
Starting procedure.
IF ENGINE FAILS TO START
If the engine fails to start after you have followed
the “Normal Starting” procedure and has not
experienced an Extended Park condition as
defined previously, 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 brake pedal,
wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
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.
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.
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 Ú page 338.
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 auto -
matic transmission 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 Ú page 320.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than 10
seconds at a time. Wait 10 to 15 seconds before
trying again.

SAFETY305
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
NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
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/lift -
gate/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.

SERVICING AND MAINTENANCE391
TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle
operate at different loads and perform different
steering, handling, and braking functions. For
these reasons, they wear at unequal rates.
These effects can be reduced by timely rotation of
tires. The benefits of rotation are especially
worthwhile with aggressive tread designs such as
those on On/Off-Road type tires. Rotation will
increase tread life, help to maintain mud, snow,
and wet traction levels, and contribute to a
smooth, quiet ride.
Refer to the “Maintenance Plan” for the proper
maintenance intervals. More frequent rotation is
permissible if desired. The reasons for any rapid or
unusual wear should be corrected prior to rotation
being performed.
NOTE:The premium Tire Pressure Monitoring System will
automatically locate the pressure values displayed
in the correct vehicle position following a tire
rotation. The suggested rotation method is the “rearward
cross” shown in the following diagram.

Tire Rotation (Rearward Cross)

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.
