Upon installation by your dealer, your OnStar TTY system is fully
functional for OnStar services.
*Please take a moment to familiar-
ize yourself with all the functions of the TTY system so that you’ll
be comfortable with them once you begin driving. Your OnStar TTY
system provides you with access to most of the features** described
in the OnStar Subscriber Information kit in your glove box. Be sure
to read the OnStar Owner Guide so that you understand all the
details of how the OnStar features work.
Most 2007 GM vehicles come with one year of OnStar service. Check
with your dealer or an OnStar TTY Advisor to determine what service
plan comes with your vehicle. Your TTY system is your communication
link to trained TTY Advisors at OnStar’s call centers 24/7, every day of
the year. You can press the OnStar blue button, the Emergency button,
and make phone calls using the dial pad.

a “Driver Unavailable” message. If someone called you while you

Troubleshooting:
If you are experiencing problems with your OnStar TTY system,
please check the following:
1. Make sure the LED next to your three-button OnStar system, located either in
your rearview mirror or your overhead console, is green. If the LED is not
green, please turn off your vehicle’s ignition, and then turn it back on. If the
status light next to the three button system does not illuminate, this indicates
a problem with your OnStar system. Please visit your GM dealer.
2. Make the TTY device is properly plugged into the OTIM. When the TTY
device is properly plugged in, the Status LED and the Mode LED will be
illuminated green.
If these LEDs are not illuminated, please disconnect then reconnect the
TTY device into the TTY jack, and ensure the OTIM is set to TTY mode by
pressing the Mode button until the Mode LED illuminates green.
If the lights are still not illuminated, please call OnStar via the TTY toll-free
number (877.248.2080). Ask the TTY Advisor to ensure that your OnStar
account has been activated and that you are enrolled as a TTY subscriber.
3. If you are experiencing garbled text on your TTY device, make sure the
device is fully charged. If it is fully charged, there may be cellular
connectivity issues affecting your call. In this case, please
disconnect your call and try again in a few minutes.
*Note: In an emergency situation, in addition to the red emergency
button on the OnStar 3-button system you can dial 9-1-1 on the dial pad
while the vehicle is moving. However, due to the OnStar advisor’s ability
to pinpoint your location, the red emergency button is the preferred mode
of communication in an emergency.
