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.

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.

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.

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.

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.

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.

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.

UFFETING

Wind buffeting can be described as the

perception of pressure on the ears or a

helicopter-type sound in the ears. Your vehicle

may exhibit wind buffeting with the windows

down, or the sunroof (if equipped) in certain

open or partially open positions. This is a

normal occurrence and can be minimized.

If the buffeting occurs with the rear windows

open, open the front and rear windows together

to minimize the buffeting. If the buffeting occurs

with the sunroof open, adjust the sunroof

opening to minimize the buffeting or open any

window.

WARNING!

A hot engine cooling system is dangerous.

You or others could be badly burned by steam

or boiling coolant. It is recommended to call an

authorized dealer for service if your vehicle

overheats. If you decide to look under the hood

yourself, Follow the warnings under the Cooling

System Pressure Cap paragraph

to the DEF tank. If you have a fault related to

the DEF system, the gauge may not update to

the new level. See an authorized dealer for

service.



The DEF gauge may also not immediately

update after a refill if the temperature of the

DEF fluid is below 39°F (4°C). The DEF tank

heater will possibly warm up the DEF fluid

and allow the gauge to update after a period

of run time. Under very cold conditions, it is

possible that the gauge may not reflect the

new fill level for several drives.
