OnStar Steering Wheel
Controls
This 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 3-82 for more
information.
OnStar voice command does not
work unless Personal Calling
is activated. To activate Personal
Calling, see the OnStar Owner’s
Guide.
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 vehicles 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 vehicles
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 are
other 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.
