Potential Issues

Unlock or Stolen Vehicle Assistance
after the vehicle has been off
continuously for 10 days without an
ignition cycle. If the vehicle has not
been started for 10 days, OnStar can
contact Roadside Service or 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.
Cellular and GPS Antennas
Cellular reception is required for
OnStar to send remote signals to the
vehicle. Do not place items over or
near the antenna to prevent blocking
cellular and GPS signal reception.
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
|
to 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
. Added electrical
equipment may interfere with the
operation of the OnStar system and
cause it to not operate.
