in that area. The wireless service
provider must also have coverage,
network capacity, reception, and
technology compatible with OnStar
services. Service involving location
information about the vehicle cannot
work unless GPS signals are
available, unobstructed, and
compatible with the OnStar
hardware. OnStar services may not
work if the OnStar equipment is not
properly installed or it has not been
properly maintained. If equipment or
software is added, connected,
or modified, OnStar services may
not work. Other problems beyond
the control of OnStar may prevent
service such as hills, tall buildings,
tunnels, weather, electrical system
design and architecture of the
vehicle, damage to the vehicle in a
crash, or wireless phone network
congestion or jamming.

Potential Issues
OnStar cannot perform Remote
Door Unlock or Stolen Vehicle
Assistance after the vehicle has
been off continuously for five days.
After 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,
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.A temporary loss of GPS can cause
loss of the ability to send a
Turn-by-Turn Navigation route. The
Advisor may give a verbal route or
may ask for a call back after the
vehicle is driven into an open area.
Cellular and GPS Antennas
Do not place items over or near the
antenna to prevent blocking cellular
and GPS signal reception. Cellular
reception is required for OnStar to
send remote signals to the vehicle.
Unable to Connect to OnStar
Message
If there is limited cellular coverage
or the cellular network has reached
maximum capacity, this message
may come on. Press
Qto try the
call again or try again after driving a
few miles into another cellular area.
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.
Add-on Electrical Equipment
The OnStar system is integrated
into the electrical architecture of the
vehicle. Do not add any electrical
equipment. See
Add-On Electrical
Equipment on page 9-57. Added
electrical equipment may interfere
with the operation of the OnStar
system and cause it to not operate.
