OnStar®System
OnStar®uses several innovative
technologies and live advisors to
provide a wide range of safety,
security, navigation, diagnostics,
and calling services.
Automatic Crash Response
In a crash, built in sensors can
automatically alert an OnStar
advisor who is immediately
connected to the vehicle to see
if you need help.
How OnStar Service Works
Q: This blue button connects you
to a specially trained OnStar advisor
to verify your account information
and to answer questions.
]: Push this red emergency
button to get priority help from
specially trained OnStar emergency
advisors.

voice‐activated calling and to give
voice commands for turn‐by‐turn
navigation.
Crisis Assist, Stolen Vehicle
Assistance, Vehicle Diagnostics,
Remote Door Unlock, Roadside
Assistance, Turn‐by‐Turn Navigation
and Hands‐Free Calling are
available on most vehicles. Not all
OnStar services are available on
all vehicles. For more information
see the OnStar Owner's Guide or
visit www.onstar.com (U.S.) or
www.onstar.ca (Canada), contact
OnStar at 1-888-4-ONSTAR

24 hours a day, 7 days a week. For a full description of OnStar
services and system limitations,
see the OnStar Owner's Guide in
the glove box.
OnStar service is subject to the
OnStar terms and conditions
included in the OnStar Subscriber
Information.
OnStar service cannot work unless
the 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 the vehicle is 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.

4-42 Instruments and Controls
The OnStar system can record and
transmit vehicle information. This
information is automatically sent to
an OnStar call center when
Qis
pressed,
]is pressed, or if the
airbags or ACR system deploy. This
information usually includes the
vehicle's GPS location and, in the
event of a crash, additional
information regarding the crash that
the vehicle was involved in (e.g. the
direction from which the vehicle was
hit). When the virtual advisor feature
of OnStar hands-free calling is
used, the vehicle also sends OnStar
the vehicle's GPS location so they
can provide services where it is
located.
Location information about the
vehicle is only available if the GPS
satellite signals are unobstructed
and available. The vehicle must have a working
electrical system, including
adequate battery power, for the
OnStar equipment to operate. There
are other problems OnStar cannot
control that may prevent OnStar
from providing OnStar service at
any particular time or place. Some
examples are damage to important
parts of the vehicle in a crash, hills,
tall buildings, tunnels, weather or
wireless phone network congestion.
OnStar Steering Wheel
Controls
This vehicle may have a Talk/Mute
button that can be used to interact
with OnStar hands-free calling. See
Steering Wheel Controls
on
page 4‑6for more information. On some vehicles, the mute button
can be used to dial numbers into
voice mail systems, or to dial phone
extensions. See the OnStar Owner's
Guide for more information.
Your Responsibility
Increase the volume of the radio if
the OnStar advisor cannot be heard.
If the light next to the OnStar
buttons is red, the system may
not be functioning properly.
Press
Qand request a vehicle
diagnostic. If the light appears clear
(no light is appearing), your OnStar
subscription has expired and all
services have been deactivated.
Press
Qto confirm that the OnStar
equipment is active.
