OnStar Information
Positioning Capability Degraded if
Satellite Signals Are Obstructed
Vehicle position is determined by receiving and
interpreting signals transmitted by satellites. If the
signals are obstructed, positioning capability could
be degraded or lost. This situation would be most
prevalent in urban areas where tall buildings are
located. Tunnels, underpasses, parking garages, trees,
and similar structures could also adversely affect
positioning performance. Under these conditions, the
system will operate but the OnStar Call Center could
have difficulty identifying your current location. The last
valid position obtained before the obstruction is retained,
however, and can be sent. The OnStar Advisor may
depend on you to provide verbal information regarding
your vehicle’s location if such an obstruction of the
satellites occurs.
Communications Issues
Privacy
Users of wireless communications are cautioned that
the privacy of any information sent via wireless cellular
communications cannot be assured. Third parties
may unlawfully intercept or access transmissions and
private communications without your consent.
Inoperative if Cellular Signal
Is Marginal or Unavailable
Since OnStar uses the cellular technology for
communication with the OnStar Call Center, it can
only be operated in geographic areas where cellular
coverage is available. Although nearly all of the
North American population lives and works in cellular
coverage areas, there are various rural and mountainous
areas where coverage is marginal or does not exist.
Cellular service is also subject to transmission limitations
