affect or erase data or settings that
are stored in the vehicle, such as
OnStar Hands-Free Calling name

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

consent to these software updates
or changes and agreement that

deliver them to the vehicle.
