If equipped, two Mini-USB Ports (Type C), two
Standard USB Ports (Type A), and one AUX port
may be located to the left of the center stack,
just below the climate controls.
Center Console USB/AUX Media Hub

Some USB ports support media and charging.
You can use features, such as Apple CarPlay®,
Android Auto™, Pandora®, and others while
charging your phone.
NOTE:

Plugging in a phone or another USB device may
cause the connection to a previous device to be lost.

ELECTRICAL POWER OUTLETS
The auxiliary 12 Volt (13 Amp) power outlet can
provide power for in-cab accessories designed
for use with the standard “cigarette lighter”
style plug. The 12 Volt power outlets and 5 Volt
(2.5 Amp) USB port (Charge Only) have a cap
attached to the outlet indicating “12V DC”,
together with either a key symbol, battery
symbol, or USB symbol.
A key symbol indicates that the ignition must be
in the ON/RUN or ACC positions for the outlet to
provide power. The battery symbol indicates
that the outlet is connected to the battery, and
can provide power at all times.
An auxiliary power outlet can be found in the
tray on top of the center stack. This power outlet
works when the ignition is in the ON/RUN, ACC,
or OFF position.

Power Outlet — Top Of Center Stack

1 — Standard USB Type A Ports
2 — Mini-USB Type C Ports
3 — AUX Port
CAUTION!
Do not exceed the maximum power of
160 Watts (13 Amps) at 12 Volts. If the
160 Watts (13 Amps) power rating is
exceeded, the fuse protecting the system
will need to be replaced.
Power outlets are designed for accessory
plugs only. Do not insert any other object in
the power outlets as this will damage the
outlet and blow the fuse. Improper use of
the power outlet can cause damage not
covered by your New Vehicle Limited
Warranty.

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

Center Stack Power Inverter
To turn on the power outlet, simply plug in the
device. The outlet turns off when the device is
unplugged.
NOTE:
The power inverter only turns on if the ignition
is in the ACC or ON/RUN position.
Due to built-in overload protection, the power
inverter shuts down if the power rating is
exceeded.
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.
If this outlet is mishandled, it may cause an
electric shock and failure.

SAFETY333
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 maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with
all side windows fully open.

426SERVICING AND MAINTENANCE
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,
under-inflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.
