How Onstar Service Works - Chevrolet 2008 Equinox Owner's Manual

OnStar Steering Wheel Controls
Your vehicle may have a Talk/Mute button that can
be used to interact with OnStar Hands-Free Calling.
See Audio Steering Wheel Controls on page 3-108 for
more information.
On some vehicles, you may have to hold the button
for a few seconds and give the command "ONSTAR" to
activate the OnStar Hands-Free Calling.
On some vehicles, the mute button can be used to
dial numbers into voicemail systems, or to dial phone
extensions. See the OnStar Owner's Guide for
more information.

How OnStar Service Works

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.
Location information about your vehicle is only available
if the GPS satellite signals are unobstructed and
available.
