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 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)
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.

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, elec -
tronics 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 igni -
tion is in the ACC or ON/RUN mode.

inverter shuts down if the power rating is
exceeded.
Wireless Charging Pad — If Equipped

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 wire
-
less 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.
WARNING!
To avoid serious injury or death:
Do not insert any objects into the recepta -
cles.
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.
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.
