OnStar service requires wireless communication
networks and the Global Positioning System (GPS)
satellite network. Not all OnStar services are available
everywhere or on all vehicles at all times.
OnStar service can’t work unless your vehicle is in
a place where OnStar has an agreement with a
wireless service provider for service in that area, and
the wireless service provider has coverage, network
capacity, reception, and technology compatible with
OnStar's service. Service involving location information
about your vehicle can’t work unless GPS signals are
available, unobstructed, and compatible with the OnStar
hardware. The vehicle has to have a working electrical
system and adequate battery power for the OnStar
equipment to operate. OnStar service may not work if
the OnStar equipment isn’t properly installed or you
haven’t maintained it and your vehicle is in good
working order and in compliance with all government
regulations. If you try to add, connect, or modify any
equipment or software in your vehicle, OnStar service
may not work. Other problems OnStar can’t control may
prevent service to you, such as hills, tall buildings,
tunnels, weather, electrical system design and
architecture of your vehicle, damage to important parts
of your vehicle in a crash, or wireless phone network
congestion or jamming.See
Radio Frequency Statementon page 8‑20for information regarding Part 15 of the Federal
Communications Commission (FCC) rules and
Industry Canada Standards RSS-210/220/310.
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 4‑124for 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. Push the
Qbutton and
request a vehicle diagnostic. If the light appears clear
(no light appears), your OnStar subscription has
expired and all services have been deactivated. Push
the
Qbutton to confirm that the OnStar equipment is
active.

{WARNING:
A crash severe enough to inflate the airbags may
have also damaged important functions in the
vehicle, such as the fuel system, brake and
steering systems, etc. Even if the vehicle appears
to be drivable after a moderate crash, there may
be concealed damage that could make it difficult
to safely operate the vehicle.
Use caution if you should attempt to restart the
engine after a crash has occurred.In many crashes severe enough to inflate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front passenger airbag..Airbags are designed to inflate only once. After an
airbag inflates, you will need some new parts for
the airbag system. If you do not get them, the
airbag system will not be there to help protect you
in another crash. A new system will include airbag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
.The vehicle has a crash sensing and diagnostic
module which records information after a crash.
See
Vehicle Data Recording and Privacy
on
page 8‑19and Event Data Recorderson
page 8‑19.
.Let only qualified technicians work on the airbag
systems. Improper service can mean that an
airbag system will not work properly. See your
dealer for service.
2-65

Black plate (69,1)Cadillac STS Owner Manual - 2011
Safety belts help keep the passenger in position on the
seat during vehicle maneuvers and braking, which helps
the passenger sensing system maintain the passenger
airbag status. See“Safety Belts”and“Child Restraints”
in the Index for additional information about the
importance of proper restraint use.
{WARNING:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on, it
means that something may be wrong with the
airbag system. If this ever happens, have the
vehicle serviced promptly, because an adult-size
person sitting in the right front passenger's seat
may not have the protection of the airbag(s). See
Airbag Readiness Light
on page 4‑54for more
on this, including important safety information.
A thick layer of additional material, such as a blanket
or cushion, or aftermarket equipment such as seat
covers, seat heaters, and seat massagers can affect
how well the passenger sensing system operates.
