rates may apply.

appear on the infotainment display. Proactive Alerts are
designed to help predict specific
types of issues based on
information collected from the
vehicle. Other factors may affect
vehicle performance. Not all issues
will deliver alerts. In some cases, a
dealer service check may be
required to confirm the accuracy
of the alerts.

maintenance. Your dealer will then

problems beyond the control of
OnStar—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 —may prevent service.
See Radio Frequency Statement 0344.

ignition cycle. If the vehicle has not
been started for 10 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.

ONSTAR 355
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 0230. 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 statement or separately
disclosed at the time of installation.
These updates or changes may also
cause a system to automatically
communicate with GM servers to
collect information about vehicle
system status, identify whether
updates or changes are available,
or deliver updates or changes. An
active OnStar agreement constitutes
consent to these software updates or
changes and agreement that either
OnStar or GM may remotely deliver
them to the vehicle.
