for an extended period of time while the
vehicle is off will drain the battery.
Always unplug electrical equipment when
not in use and do not plug in equipment
that exceeds the maximum 15 amp
rating.
Certain power accessory plugs may not be
compatible with the accessory power outlet
and could overload vehicle or adapter fuses.
If a problem is experienced, see your dealer. When adding electrical equipment, be sure
to follow the proper installation instructions
included with the equipment. See
Add-On
Electrical Equipment 0306.
Caution
Hanging heavy equipment from the
power outlet can cause damage not
covered by the vehicle warranty. The
power outlets are designed for accessory
power plugs only, such as cell phone
charge cords.
Power Outlet 110/120 Volt Alternating
Current

When the ignition is on, power to the 110
Volt outlet is enabled after the
-
button is pressed, seeInstrument Panel
Overview 04for button location. A green
indicator light on the button indicates when
the 110 Volt outlet is enabled. 110 Volt
power is supplied to the outlet when it is
enabled and electrical equipment is plugged
into that outlet. One power outlet can be
used with electrical equipment that uses a
maximum of 400 watts. Ensure that all
connected devices do not exceed 400 watts.
The power outlet can be turned off by
pressing the
-button. An indicator light on the outlet illuminates
when the system is enabled and no system
fault is detected. The outlet will not provide
power when the ignition is off, the
-
button is not pressed, or the plug is not
fully seated into the outlet. The outlet does
not operate while the engine is starting. If a
USB powered streaming device is being
used, it is suggested to use a USB Port for
power, see
USB Port0152. If uninterrupted
power supply is required while driving,
disable the auto-stop feature, see Stop/Start
System 0229.
If equipment is connected using more than
400 watts or a system fault is detected, a
protection circuit shuts off the power supply
and the indicator light will flash.
Do not use a power outlet with a missing or
damaged cover.
The power outlet is not designed for the
following, and may not work properly if
they are plugged in:
.Equipment with high initial peak wattage,
such as compressor-driven refrigerators
and electric power tools
.Other equipment requiring an extremely
stable power supply, such as
microcomputer-controlled electric blankets
and touch sensor lamps
.Medical equipment
Wireless Charging
If equipped and enabled, the system
operates at 145 kHz and wirelessly charges
one Qi compatible smartphone. The power
output of the system is capable of charging
at a rate up to 3 amp (15 W), as requested
by the compatible smartphone. See Radio
Frequency Statement 0407.
{Warning
Wireless charging can affect the
operation of an implanted pacemaker or
other medical devices. If you have one, it
is recommended to consult with your
doctor before using the wireless charging
system.
The vehicle must be on, in ACC/ACCESSORY,
or Retained Accessory Power (RAP) must be
active. The wireless charging feature may
not correctly indicate charging when the

The operating temperature is −20 °C (−4 °F)
to 60 °C (140 °F) for the charging system
and 0 °C (32 °F) to 35 °C (95 °F) for the
phone.
{Warning
Remove all objects from the charging pad
before charging your compatible
smartphone. Objects, such as coins, keys,
rings, paper clips, or cards, between the
smartphone and charging pad will
become very hot. On the rare occasion
that the charging system does not detect
an object, and the object gets wedged
between the smartphone and charger,
remove the smartphone and allow the
object to cool before removing it from
the charging pad, to prevent burns.
To charge a compatible smartphone:
1. Remove all objects from the charging pad. The system may not charge if there
are any objects between the smartphone
and charging pad.
2. Place the smartphone face up against the bottom edge of the charge pad.
To maximize the charge rate, ensure the
smartphone is fully seated and centered
in the holder with nothing under it.
A thick smartphone case may prevent
the wireless charger from working,
or may reduce the charging performance.
See your dealer for additional
information. 3. A green
}will appear on theVon
the infotainment display. This indicates
that the smartphone is properly
positioned and charging. If a smartphone
is placed on the charging pad and
}
does not display, remove the
smartphone from the pad, turn it
180 degrees, and wait three seconds
before placing/aligning the smartphone
on the pad again.
4. If
}turns yellow, ensure that the
charging pad is clear of any objects and
that the smartphone is capable of
wireless charging before re-positioning it.
If
}does not illuminate, the
smartphone may need to re-positioned.
The smartphone may become warm
during charging. This is normal. In
warmer temperatures, the speed of
charging may be reduced.

Universal Remote System
Programming
If equipped, these buttons are in the
overhead console.
This system can replace up to three remote
control transmitters used to activate devices
such as garage door openers, security
systems, and home automation devices.
These instructions refer to a garage door
opener, but can be used for other devices.
Do not use the Universal Remote system
with any garage door opener that does not
have the stop and reverse feature. This
includes any garage door opener model
manufactured before April 1, 1982. Read the instructions completely before
programming the Universal Remote system.
It may help to have another person assist
with the programming process.
Keep the original hand-held transmitter for
use in other vehicles as well as for future
programming. Erase the programming when
vehicle ownership is terminated. See
“Erasing Universal Remote System Buttons”
later in this section.
To program a garage door opener, park
outside directly in line with and facing the
garage door opener receiver. Clear all people
and objects near the garage door.
Make sure the hand-held transmitter has a
new battery for quick and accurate
transmission of the radio-frequency signal.
Programming the Universal Remote
System
For questions or programming help, see
www.homelink.com/gm or call
1-800-355-3515. For calls placed outside the
U.S., Canada, or Puerto Rico, international
rates will apply and may differ based on
landline or mobile phone.

Radio Signals for Some Gate Operators
For questions or programming help, see
www.homelink.com/gm or call
1-800-355-3515. For calls placed outside the
U.S., Canada, or Puerto Rico, international
rates will apply and may differ based on
landline or mobile phone.
Some radio–frequency laws and gate
operators require transmitter signals to time
out or quit after several seconds of
transmission. This may not be long enough
for the Universal Remote system to pick up
the signal during programming.
If the programming did not work, replace
Step 2 under“Programming the Universal
Remote System” with the following:
Press and hold the Universal Remote system
button while pressing and releasing the
hand-held transmitter button every
two seconds until the signal has been
successfully accepted by the Universal
Remote system. The Universal Remote
system indicator light will flash slowly at
first and then change to a rapid flash or
continuous solid-light. Proceed with Step 3
under “Programming the Universal Remote
System” to complete.
Universal Remote System
Operation
Using the Universal Remote System
Press and hold the appropriate Universal
Remote system button for at least one-half
second. The indicator light will come on
while the signal is being transmitted.
Erasing Universal Remote System
Buttons
Erase all programmed buttons when vehicle
ownership is terminated.
To erase:
1. Press and hold the two outside buttons until the indicator light begins to flash.
This should take about 10 seconds.
2. Release both buttons.
Reprogramming a Single Universal
Remote System Button
To reprogram any of the system buttons: 1. Press and hold any one of the buttons. Do not release the button.
2. The indicator light will begin to flash after 20 seconds. Without releasing the
button, proceed with Step 1 under
“Programming the Universal Remote
System.”
