change the OnStar PIN, call OnStar
and provide the Advisor with the
current number.
Warranty
OnStar equipment may be
warranted as part of the New
Vehicle Limited Warranty. The
manufacturer of the vehicle
furnishes detailed warranty
information.
Languages
The vehicle can be programmed to
respond in multiple languages.
Press
Qand ask an Advisor.
Advisors are available in English,
Spanish and French. Available
languages may vary by country.
Potential Issues
OnStar cannot perform Remote
Door Unlock or Stolen Vehicle
Assistance after the vehicle has
been off continuously for five days. After five days, OnStar can contact
Roadside Assistance and 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,
underpasses, or parking
garages; 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 verbalroute or may ask for a call back
after the vehicle is driven into an
open area.
Cellular and GPS Antennas
Avoid placing items over or near the
antenna to prevent blocking cellular
and GPS signal reception. Cellular
reception is required for OnStar to
send remote signals to the vehicle.
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.
