How OnStar®Service Works
In order to provide you with OnStar®services,
your vehicle’s OnStar®system has the capability
of recording and transmitting vehicle information.
This information is automatically sent to an
OnStar
®Call Center at the time of an OnStar®
button press, Emergency button press or if
your airbags or AACN system deploys. The vehicle
information usually includes your GPS location
and, in the event of a crash, additional information
regarding the accident that your vehicle has
been involved in (e.g. the direction from which
your vehicle was hit). When you use the
Virtual Advisor feature of OnStar
®Hands-Free
Calling, your vehicle also sends OnStar®your
GPS location so that we can provide you
with location-based services.OnStar
®service cannot work unless your 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
you are 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.
OnStar
®service that involves location information
about your vehicle cannot work unless GPS
satellite signals are unobstructed and available
in that place as well.

Your 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 to you at any particular time or place.
Some examples are damage to important parts
of your vehicle in an accident, hills, tall buildings,
tunnels, weather or wireless phone network
congestion.
Your Responsibility
You may need to increase the volume of your
radio to hear the OnStar®advisor. If the light
next to the OnStar®buttons is red, this means
that your system is not functioning properly
and should be checked by a dealer. If the light
appears clear (no light is appearing), your
OnStar
®subscription has expired. You can
always press the blue OnStar®button to
con rm that your OnStar®equipment is active.
Storage Areas

Cupholder(s)
Your vehicle may have two cupholders located
on the lower part of the front doors as well as
two cupholders located at the front end of
the console. Vehicles with bench seats may
have cupholders attached to the front of the
center seat.

are located on top of the rear center console.

Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical system
for malfunctions. The light tells you if there is
an electrical problem. The system check includes
the airbag sensors, the airbag modules, the
wiring and the crash sensing and diagnostic
module. For more information on the airbag
systems, seeAirbag System on page 77.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not in ate in
a crash, or they could even in ate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced
right away if the airbag readiness light
stays on after you start your vehicle.
The airbag readiness light should ash for a
few seconds when you turn the ignition key to ON.
If the light does not come on then, have it xed
so it will be ready to warn you if there is a problem.
