For a full description of OnStar services and system
limitations, see the OnStar Owner's Guide in the
glove box.
OnStar service is subject to the OnStar terms and
conditions included in the OnStar Subscriber
Information.
OnStar service cannot work unless the vehicle is in a
place where OnStar has an agreement with a wireless
service provider for service in that area. OnStar service
also cannot work unless the vehicle is in a place where
the wireless service provider OnStar has hired for that
area has coverage, network capacity and reception
when the service is needed, and technology that is
compatible with the OnStar service. Not all services are
available everywhere, particularly in remote or enclosed
areas, or at all times.
The OnStar system can record and transmit vehicle
information. This information is automatically sent to an
OnStar call center when
Q is pressed, ] is pressed,
or if the airbags or ACR system deploy.
This information usually includes the vehicle's GPS
location and, in the event of a crash, additional
information regarding the crash that the vehicle was
involved in (e.g. the direction from which the vehicle
was hit). When the virtual advisor feature of OnStar
hands-free calling is used, the vehicle also sends
OnStar the vehicle's GPS location so they can provide
services where it is located.
Location information about the vehicle is only available
if the GPS satellite signals are unobstructed and
available.
The vehicle must have a working electrical system,
including adequate battery power, for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service at any particular time or place. Some
examples are damage to important parts of the vehicle
in a crash, hills, tall buildings, tunnels, weather or
wireless phone network congestion.
