OnStar Owner’s Guide
Your system may be inoperative if
cellular signal is marginal or unavailable.
Since OnStar uses cellular technology for communication
with the OnStar Center, it can only be operated in
geographic areas where there is cellular coverage reception
and capacity. Although nearly all of the North American
population lives and works in cellular coverage areas, there
are various rural and mountainous areas where coverage is
marginal or does not exist. Cellular service is also
subject to transmission limitations caused by atmospheric
conditions. OnStar service is only available in the
continental United States, Hawaii, Alaska, and Canada. If a
request for service occurs outside of these areas,
communications may not be available, and the OnStar
Advisor may not be able to help you. OnStar service may
also be inoperative if wireless communications service is
inactive or inoperative. OnStar uses a dedicated cellular
communications service and will not operate if, for some
reason, a cellular carrier has deactivated cellular service.
Or it may be inoperative if the cellular system is busy. In
any area, the local cellular system can handle only a limited
number of cellular calls at a given time. Once usage
volume has reached its maximum, additional callers are
denied access. If this situation occurs when an OnStar
request for services is made, the OnStar system will
automatically redial (a few times for OnStar services or
indefinitely for an air bag deploy, or an Emergency
button press). There may be other factors that are
outside of OnStar’s control that may affect or prevent
service. If you pressed the OnStar button and you heard
the message, “I’m sorry. I couldn’t connect to
OnStar.” Press the OnStar button again the system has
