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.

extensions. See the OnStar Owner's Guide for more
information.

{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. For example, the right
front passenger airbag could inflate even though
the airbag on-off switch is turned off.
To help avoid injury to yourself or others, have
the vehicle serviced right away. SeeAirbag
Readiness Light
on page 4‑33for more
information, including important safety information.
If the vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, a rear-facing
child restraint should not be installed in the vehicle,
even if the airbag is off. If the child restraint has the LATCH system, see
Lower
Anchors and Tethers for Children (LATCH)
on
page 2‑50for how and where to install the child
restraint using LATCH. If a child restraint is secured
using a safety belt and it uses a top tether, see Lower
Anchors and Tethers for Children (LATCH)
on
page 2‑50for top tether anchor locations.
Do not secure a child restraint in a position without a
top tether anchor if a national or local law requires that
the top tether be anchored, or if the instructions that
come with the child restraint say that the top strap must
be anchored.
In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached.
