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 0239. 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
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.Privacy

Statement may be found at
www.onstar.com (U.S.),
