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
only works when the ignition is in the ON/RUN
or ACC 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.

Power Outlet Fuse Locations

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
A 115 Volt (400 Watts Maximum) inverter may
be located inside the center console towards
the right hand side. 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.
