OnStar®System
OnStar®uses several innovative

OnStar services are available on
all vehicles. For more information

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.

4-42 Instruments and Controls
The OnStar system can record and
transmit vehicle information. This
information is automatically sent to
an OnStar call center when
Qis
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.

voice mail systems, or to dial phone
extensions. See the OnStar Owner's
Guide for more information.
