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. Cellu-

lar 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 situa-

tion occurs when an OnStar request for services is made, the OnStar system

will automatically redial (a few times for OnStar services or indeﬁ nitely for

an air bag deploy, or an Emergency button push). There may be other factors

that are outside of OnStar’s control that may affect or prevent service. If you

pushed the OnStar button and you heard the message “I’m sorry, I couldn’t

connect to OnStar,” push the OnStar button again. The system has several

methods it can use to connect you to the OnStar Call Centers. The OnStar

system in your vehicle can attempt to connect you by using several cellular

carriers. If these attempts fail, this message response will play. After a few

moments, or after you have driven a few miles into another cellular network,

try pushing the OnStar button again. If this message continues, please
