Potential Issues

been off continuously for five days
without an ignitions cycle. If the
vehicle cannot be started for
five days, OnStar can contact
Roadside Assistance and a
locksmith to help gain access to the
vehicle.
Global Positioning
System (GPS)
. Obstruction of the GPS can
occur in a large city with tall
buildings; in parking garages;
around airports; in tunnels, and
underpasses; or in an area with
very dense trees. If GPS signals
are not available, the OnStar
system should still operate to
call OnStar. However, OnStar
could have difficulty identifying
the exact location.
. In emergency situations, OnStar
can use the last stored GPS
location to send to emergency
responders.

Vehicle and Power Issues
OnStar services require a vehicle
electrical system, wireless service,
and GPS satellite technologies to be available and operating for features
to function properly. These systems
may not operate if the battery is
discharged or disconnected.

The OnStar system is integrated
into the electrical architecture of the
