ONSTAR 413
TTY Users
OnStar has the ability to communicate
to deaf, hard-of-hearing,
or speech-impaired customers while in
the vehicle. The available
dealer-installed TTY system can
provide in-vehicle access to all OnStar
services, except Virtual Advisor and
OnStar Turn-by-Turn Navigation.
If equipped, TTY mode can be turned
on or off by touching Settings, then
Apps, and then Phone. When TTY
mode is on, phone calls can be made
or received with OnStar using the
infotainment display.
OnStar Personal Identification
Number (PIN)
A PIN is needed to access some
OnStar services. The PIN will need to
be changed the first time when
speaking with an Advisor. To change
the OnStar PIN, contact an OnStar
Advisor by pressing
Qor calling
1-888-4ONSTAR.
Warranty
OnStar equipment may be warranted
as part of the vehicle warranty.
Languages
The vehicle can be programmed to
respond in multiple languages. Press
Qand ask for an Advisor. Advisors
are available in English, Spanish, and
French. Available languages may vary
by country.
Potential Issues
OnStar cannot perform Remote Door
Unlock or Stolen Vehicle Assistance
after the vehicle has been off
continuously for an extended period
of time without an ignition cycle. To
find out the duration of time that
applies for the vehicle, contact an
OnStar Advisor by pressing
Qor
calling 1-888-4ONSTAR. If the vehicle
has not been started for an extended
period of time, OnStar can contact
Roadside Service or a locksmith to
help gain access to the vehicle.
Global Positioning System (GPS)
.Obstruction of the GPS can occur in
a large city with tall buildings; in
parking garages; around airports; in
tunnels and underpasses; or in an
area with very dense trees. If GPS signals are not available, the OnStar
system should still operate to call
OnStar. However, OnStar could have
difficulty identifying the exact
location.
.In emergency situations, OnStar can
use the last stored GPS location to
send to emergency responders.
A temporary loss of GPS can cause
loss of the ability to send a
Turn-by-Turn Navigation route. The
Advisor may give a verbal route or
may ask for a call back after the
vehicle is driven into an open area.
Cellular and GPS Antennas
Cellular reception is required for
OnStar to send remote signals to the
vehicle. Do not place items over or
near the antenna to prevent blocking
cellular and GPS signal reception.
Unable to Connect to OnStar
Message
If there is limited cellular coverage or
the cellular network has reached
maximum capacity, this message may
