®
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 227 for more information.
On some vehicles, you may have to hold the
button for a few seconds and give the command
“ONSTAR” in order to activate the OnStar
®
Hands-Free Calling feature.
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
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.
