vehicle has not been started for
five days, OnStar can contact
Roadside Assistance 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.
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
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
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 0224. Added electrical
equipment may interfere with the
operation of the OnStar system and
cause it to not operate.
Vehicle Software Updates
OnStar or GM may remotely deliver
software updates or changes to the
vehicle without further notice or
consent. These updates or changes
may enhance or maintain safety,
security, or the operation of the
vehicle or the vehicle systems.
Software updates or changes may
affect or erase data or settings that
are stored in the vehicle, such as
OnStar Hands-Free Calling name
tags, saved navigation destinations,
or pre-set radio stations. Neither
OnStar nor GM is responsible for
any affected or erased data or
settings. These updates or changes
may also collect personal
information. Such collection is
described in the OnStar privacy
