Instruments and Controls 99
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
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 0409.
{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

calls. SeeRetained Accessory Power (RAP)
0 229.
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 at 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.

The RSI includes two or four new 2-channel
digital wireless headphones, depending on
the vehicle model. The headphones are used
to listen to various multimedia. The wireless
headphones have a power button, Channel 1 or 2 switch, and a volume control. The
digital headphones cannot be interchanged
with previous models of GM headphones.
Press the power button to turn on the
headphones. A light on the headphones
should come on. A flashing light indicates
the headphones are not in range. Move
them closer to the forward overhead screen
until the light stops flashing. If the light
does not come on, check the batteries.
Intermittent sound or static can also indicate
weak batteries. See
“Battery Replacement”
later in this section.
Turn the headphones off when they are not
in use.
Press the center of the right side of the
headphone to change the channel. Channel 1
will provide audio associated with
screen 1 and channel 2 will provide audio
associated with screen 2.
Infrared transmitters are on the top of the
right seatback video screen. The headphones
shut off automatically to save the battery
power if the RSI system is off or if the
headphones are out of range of the
transmitters for more than three minutes.
Moving too far forward or stepping out of
the vehicle can cause the headphones to
lose the signal or have static. Use the volume control on the headphones
to adjust the volume.
For best audio performance, wear the
headphones as indicated with L (Left) and
R (Right) on the ear pads. Do not let
anything cover the ear pads.
Caution
Do not store the headphones in heat or
direct sunlight. This could damage the
headphones and repairs would not be
covered by the vehicle warranty. Storage
in extreme cold can weaken the batteries.
Keep the headphones stored in a cool,
dry place.
If the foam ear pads become worn or
damaged, the pads can be replaced
separately. To purchase replacement ear
pads, call 1-888-293-3332 or contact your
dealer.
Battery Replacement
To change the batteries: 1. Loosen the screw to the battery door on the left side of the headphones.
2. Slide the battery door open.
3. Replace the two AAA batteries.

4. Replace the battery door and tighten thescrew.
Remove the batteries if the headphones will
not be used for a long time.
RSI Troubleshooting
No power : The ignition might not be on or
in ACC/ACCESSORY.
There is no sound from the headphones
with the indicator light on : If the batteries
are good, make sure the headphones are
programmed to the correct screen and on
the correct channel for the screen being
viewed.
Sometimes the wireless headphone audio
cuts out or buzzes : Check for obstructions,
low batteries, reception range, and
interference from cell phone towers or from
cellular telephone use in the vehicle. Check
that the headphones are on correctly using
the L (Left) and R (Right) on the
headphones. Check that the headphones are
positioned properly with the headband
across the top of the head.
Newer mobile phones and tablets emit
infrared light for features like face and iris
detection. This infrared light can interfere
with both the headphone operation. If your headphones experience static or dropouts,
place your mobile device away from the
rear seat displays.
I lost the headphones :
See your dealer for
assistance.
Video Distortion
Video distortion can occur when operating
cellular phones, scanners, CB radios, Global
