How OnStar ® Service Works
In order to provide you with OnStar ® services, your
vehicle’s OnStar ® system has the capability of
recording and transmitting vehicle information. This
information is automatically sent to an OnStar
® Call
Center at the time of an OnStar ® button press,
Emergency button press or if your airbags or AACN
system deploys. The vehicle information usually
includes your GPS location and, in the event of a
crash, additional information regarding the accident
that your vehicle has been involved in (e.g. the
direction from which your vehicle was hit). When
you use the Virtual Advisor feature of OnStar
®
Hands-Free Calling, your vehicle also sends
OnStar
® your GPS location so that we can provide
you with location-based services.
OnStar
® service cannot work unless your vehicle is
in a place where OnStar ® has an agreement with a
wireless service provider for service in that area.
OnStar
® service also cannot work unless you are in
a place where the wireless service provider
OnStar
® has hired for that area has coverage,
network capacity and reception when the service is
needed, and technology that is compatible with the
OnStar
® service.
Not all services are available everywhere,
particularly in remote or enclosed areas, or at
all times.
OnStar ® service that involves location information
about your vehicle cannot work unless GPS
satellite signals are unobstructed and available in
that place as well.
Your vehicle must have a working electrical system
(including adequate battery power) for the OnStar
®
equipment to operate. There are other problems
OnStar
® cannot control that may prevent OnStar ®
from providing OnStar ® service to you at any
particular time or place. Some examples are
damage to important parts of your vehicle in an
accident, hills, tall buildings, tunnels, weather or
wireless phone network congestion.
Your Responsibility
You may need to increase the volume of your radio
to hear the OnStar
® advisor. If the light next to the
OnStar ® buttons is red, this means that your system
is not functioning properly and should be checked
by your dealer/retailer. If the light appears clear (no
light is appearing), your OnStar
® subscription has
expired. You can always press the OnStar ® button
to confirm that your OnStar ® equipment is active.
