OnStar Hands-Free Calling
General tips for interacting with the system
• Speaking numbers: To ensure your calls are connected
everywhere you go, always dial and store 11-digit phone
numbers using a “1” and the area code. You can also say “911”
and the system will dial 911.
• The system does not recognize words such as “hundred,”
“thousand,” or “twenty.” Instead, you should say each digit
separately and continuously. For example, the phone number
“1.800.555.2030” is pronounced, “one-eight-zero-zero-five-
five-five-two-zero-three-zero.”
Steering Wheel Controls
Some vehicles may have a steering wheel
button that allows you to conveniently press
it to engage OnStar Hands-Free Calling. The
button may be a symbol of a face with sound
waves, or may say MUTE, or be a symbol of
a radio speaker with a slash through it. You
can find out if your vehicle has this feature
by pressing this button. If you hear
“OnStar ready”, that means
that your vehicle has this feature. (In some vehicles, you may need
to press and hold the button for a few seconds.) If your vehicle has
a DVD navigation system, you may need to press the button and
say “OnStar”, and then you will hear the
“OnStar ready” prompt.
After you hear
“OnStar ready” use any of the voice commands
from the previous section.
Dialing extension numbers and accessing voice
mail systems
Once you have called into an automated phone system, vehicles
with a steering wheel control may allow you to dial numbers for
phone extensions, dial numbers into Voice Mail systems and
navigate through the “PRESS 1, or PRESS 2” functions of a
business phone system. If your vehicle has this steering wheel
control function, the following paragraphs will tell you how to use
your voice to dial numbers as if you had a phone key pad.
