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.

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 Audio Steering Wheel Controls
on page 4‑132for
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.

crash. Do not drive until the head restraints for all
occupants are installed and adjusted properly.
Adjust the head restraint so that the top of the restraint
is at the same height as the top of the occupant's head.
This position reduces the chance of a neck injury in
a crash.

{WARNING:
Sitting in a reclined position when your vehicle is
in motion can be dangerous. Even if you buckle
up, your safety belts cannot do their job when you
are reclined like this.(Continued)
WARNING: (Continued)
The shoulder belt cannot do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt cannot do its job either. In a crash the
belt could go up over your abdomen. The belt
forces would be there, not at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit well
back in the seat and wear your safety belt
properly.
Do not have a seatback reclined if your vehicle is
moving.
Your vehicle has a memory function which allows seat
settings to be saved and recalled. See Memory
Features on page 2‑6.
