OnStar Hands-Free Calling
OnStar Hands-Free Calling allows eligible OnStar
subscribers to make and receive calls using voice
commands. Hands-Free Calling is fully integrated into
the vehicle, and can be used with OnStar Pre-Paid
Minute Packages. Hands-Free Calling may also
be linked to a Verizon Wireless service plan in the U.S.
or a Bell Mobility service plan in Canada, depending
on eligibility. To find out more, refer to the OnStar
Owner’s Guide in the vehicle’s glove box, visit
www.onstar.com or www.onstar.ca, or speak with an
OnStar advisor by pressing the OnStar button or calling

OnStar Virtual Advisor
OnStar Virtual Advisor is a feature of OnStar
Hands-Free Calling that uses your minutes to access

stock quotes. By pressing the phone button and giving
a few simple voice commands, you can browse
through the various topics. See the OnStar Owner’s
Guide for more information (Only available in the
continental U.S.).
