Your Responsibility
Increase the volume of the radio if the OnStar advisor cannot be heard.
If the light next to the OnStar buttons is red, the system

and request
a vehicle diagnostic. If the light appears clear (no light is
appearing), your OnStar subscription has expired and
all services have been deactivated. Press
to confirm
that the OnStar equipment is active.
