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.
CAUTION! (Continued)

F90 Fuse 20 A Yellow Instrument Panel
Power Outlet Battery Fed (If Equipped)
F91 Fuse 20 A Yellow Instrument Panel
Power Outlet Ignition Fed (If Equipped)
F93 Fuse 20 A Yellow Cigar Lighter/ Instru -
ment Panel Power Outlet (If Equipped)

When the vehicle is turned off, be sure to unplug any
equipment as to not drain the battery of the vehicle.
All accessories connected to the outlet(s) should be
removed or turned off when the vehicle is not in use
to protect the battery against discharge.

POWER INVERTER — IF EQUIPPED

If equipped, a 115 Volt (400 Watts Maximum)
inverter may be located inside the center console
towards the right hand side, just under the
Wireless Charging Pad (if equipped). 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 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.
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 sufficiently
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 intermittently and
with greater caution.
After the use of high power draw accesso -
ries, 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.

WIRELESS CHARGING PAD — IF
E
QUIPPED

Wireless Charging Pad
Your vehicle may be equipped with a 15W 3A Qi
wireless charging pad located inside of the center
console. This charging pad is designed to
wirelessly charge your Qi enabled mobile phone.
Qi is a standard that uses magnetic induction to
transfer power to your mobile device.
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.
The wireless charging pad is equipped with an
anti-slip mat, an adjustable cradle to hold your
mobile phone in place and an LED indicator light.

NOTE:
Using a phone case may interfere with wireless
charging.
WINDOWS
POWER WINDOWS — IF EQUIPPED
The window controls on the driver's door control
all the door windows.

Power Window Switches

The passenger door windows can also be
operated by using the single window controls
on the passenger door trim panel. The window
controls will operate only when the ignition is in
the ACC or ON/RUN position.
To open the window part way (manually), push
the window switch down briefly and release.
CAUTION!
The key fob should not be placed on the
charging pad or within 15 cm (150 mm) of it.
Doing so can cause excessive heat buildup
and damage to the fob. Placing the fob in
close proximity of the charging pad blocks the
fob from being detected by the vehicle and
prevents the vehicle from starting.

EDUCTION ACTIONS — IF EQUIPPED
This vehicle is equipped with an Intelligent
Battery Sensor (IBS) to perform additional
monitoring of the electrical system and status
of the vehicle battery. In cases when the IBS detects charging system
failure, or the vehicle battery conditions are
deteriorating, electrical load reduction actions
will take place to extend the driving time and
distance of the vehicle. This is done by reducing
power to or turning off non-essential electrical
loads.
Load reduction is only active when the engine is
running. It will display a message if there is a
risk of battery depletion to the point where the
vehicle may stall due to lack of electrical supply,
or will not restart after the current drive cycle.
When load reduction is activated, the message
“Battery Saver On Some Systems May Have
Reduced Power” will appear in the instrument
cluster.
These messages indicate the vehicle battery
has a low state of charge and continues to lose
electrical charge at a rate that the charging
system cannot sustain.
