On some vehicles, the mute button
can be used to dial numbers into
voice mail systems, or to dial phone
extensions. See the OnStar Owner’s
Guide for more information.
How OnStar Service Works
The OnStar system can record
and transmit vehicle information.
This information is automatically
sent to an OnStar Call Center when
the OnStar button is pressed, the
emergency button is pressed, or if
the airbags or AACN system deploy.
This information usually includes
the vehicle’s GPS location and,
in the event of a crash, additional
information regarding the crash that
the vehicle was involved in (e.g. the
direction from which the vehicle was
hit). When the Virtual Advisor feature
of OnStar Hands-Free Calling is
used, the vehicle also sends OnStar
the vehicle’s GPS location so they
can provide services where it is
located.OnStar service cannot work
unless the 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 the vehicle
is 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 the
vehicle is only available if the GPS
satellite signals are unobstructed
and available.
The vehicle must have a working
electrical system, including adequate
battery power, for the OnStar
equipment to operate. There areother problems OnStar cannot
control that may prevent OnStar
from providing OnStar service at
any particular time or place. Some
examples are damage to important
parts of the vehicle in a crash, hills,
tall buildings, tunnels, weather or
wireless phone network congestion.
Your Responsibility
Increase the volume of the radio if
the OnStar advisor cannot be heard.
If the light next to the OnStar buttons
is red, the system may not be
functioning properly. Press the
OnStar button and request a vehicle
diagnostic. If the light appears clear
(no light is appearing), your OnStar
subscription has expired and all
services have been deactivated.
Press the OnStar button to con rm
that the OnStar equipment is active.
