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

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.

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.
