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.

With head restraints that are not installed and
adjusted properly, there is a greater chance that

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.
