ONSTAR LEVEL ADJUSTMENT

To adjust the Onstar volume level find the Black/yellow wire that you cut on the 16 pin harness, you
will use the Black/yellow wire that is by itself, with no other wire with it. Push the blue Onstar button,
while the voice is speaking tap the Black/yellow wire to ground. There are 4 volume settings for
Onstar; once the 4th setting is reached and the Black/yellow wire is tapped to ground it will
automatically go back to the first volume setting. Once the volume is set it will stay at that volume
until the Black/yellow wire is tapped to ground again. This can be set during installation and then left
alone. If user adjustment is desired, a momentary contact switch (sold separately) can be added.
Connect one terminal from the switch to ground and the other terminal to the Black/yellow wire.
The volume will change one level every time the switch is pressed.
