How OnStar Service Works
The OnStar system can record and transmit vehicle
information. This information is automatically sent to an
OnStar Call Center when the OnStar button is pressed,
the emergency button is pressed, or if the airbags or
AACN 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.
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.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.
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 the OnStar button and 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 the OnStar
button to con rm that the OnStar equipment is active.

Airbag Readiness Light
The system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the airbag
modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, seeAirbag System on page 1-44.
The airbag readiness light
ashes for a few seconds
when the engine is
started. If the light does
not come on then, have it
xed immediately.{CAUTION:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
in ate in a crash, or they could even in ate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also come
on. SeeDIC Warnings and Messages on page 3-54
for more information.

If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be a
problem with the lights or the passenger sensing
system. See your dealer/retailer for service.
{CAUTION:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light on page 3-35
for more information, including important safety
information.
Voltmeter Gage
The voltmeter shows the
voltage output of the
battery. It shows the
voltage output of the
charging system while the
engine is running.
The reading changes as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, the instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) reads BATTERY VOLTAGE
LOW when the vehicle is at 10 volts or below. Have it
checked right away. Driving with the voltmeter reading at
10 volts or below could drain the battery and disable
the vehicle.Base and Z06

{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
If this warning light stays on after the engine is started,
the parking brake may still be set or there could be
a brake problem. Refer toParking Brake on page 2-32
to see if it is set. If the parking brake is not set, have
the brake system inspected right away.
If the light comes on while driving and a CHECK
BRAKE FLUID message shows on the DIC, pull off the
road and stop carefully. The pedal may be harder to
push or the pedal may go closer to the oor. It may take
longer to stop. If the light is still on, have the vehicle
towed for service. SeeTowing Your Vehicle on
page 4-28andDIC Warnings and Messages on
page 3-54for more information.
Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
brie y when the engine
is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on,
or comes on again while driving, the vehicle needs
service. If the regular brake system warning light is
not on, the vehicle still has brakes, but not antilock
brakes. If the regular brake system warning light is also
on, the vehicle does not have antilock brakes and
there is a problem with the regular brakes. SeeBrake
System Warning Light on page 3-38.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-54for all
brake related DIC messages.
