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.

GETTING TO KNOW YOUR VEHICLE75
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.

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.

21_DPF_OM_EN_USC_t.book Page 76

NOTE:
The power window switches will remain active
for up to 10 minutes after the ignition is placed
in the OFF position. Opening either front door
will cancel this feature. The timing is program -
mable within Uconnect Settings Ú page 228.
AUTOMATIC WINDOW FEATURES — IF
E
QUIPPED
Auto-Down Feature
The driver and front passenger door power
window switches have an Auto-Down feature.
Push the window switch down for a short period of time, then release, and the window will go
down automatically.
To stop the window from going all the way down
during the Auto-Down operation, pull up or push
down on the switch briefly.
Auto-Up Feature With Anti-Pinch Protection
Lift the window switch up for a short period
of time and release; the window will go up
automatically.
To stop the window from going all the way up
during the Auto-Up operation, push down on the
switch briefly.
To close the window part way, lift the window
switch briefly and release it when you want the
window to stop.
If the window runs into any obstacle during
auto-closure, it will reverse direction and then
go back down. Remove the obstacle and use
the window switch again to close the window.
NOTE:
Any impact due to rough road conditions may
trigger the auto-reverse function unexpectedly
during auto-closure. If this happens, pull the
switch lightly and hold to close the window
manually.
RESET AUTO-UP
Should the Auto-Up feature stop working, the
window probably needs to be reset. To reset
Auto-Up:

1. Pull the window switch up to close the
window completely and continue to hold
the switch up for an additional two seconds
after the window is closed.

2. Push the window switch down firmly to open the window completely and continue to hold
the switch down for an additional two
seconds after the window is fully open.
WARNING!
Never leave children unattended in a vehicle.
Do not leave the key fob in or near the vehicle
or in a location accessible to children, and do
not leave the ignition of a vehicle equipped
with Keyless Enter-N-Go in the ACC or
ON/RUN mode. Occupants, particularly
unattended children, can become entrapped
by the windows while operating the power
window switches. Such entrapment may
result in serious injury or death.
WARNING!
There is no anti-pinch protection when the
window is almost closed. To avoid personal
injury be sure to clear your arms, hands,
fingers and all objects from the window path
before closing.
