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.

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.

21_DPF_OM_EN_USC_t.book Page 74
