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 OnStar®button to con rm that your OnStar®
equipment is active.

Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC), you
may see the voltage move up or down. This is
normal. If there is a problem, an alert will be
displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very high
electrical loads.A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 200.

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 sensor, the airbag modules, the wiring and
the crash sensing and diagnostic module.
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
RUN. If the light does not come on then, have it
xed so it will be ready to warn you if there is
a problem.
176
If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s frontal airbag. SeePassenger
Sensing System on page 82for more on this,
including important safety information.
If, after several seconds, all 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 for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, 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 seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 176.
Battery Warning Light
The battery warning light
will come on brie y as a
check, when you turn on
the ignition. Then it
should go out when the
engine is started.
If the light does not come on when you start your
vehicle, have your vehicle serviced right away.
This condition may indicate your battery warning
light is not functioning properly. If this light
comes on while you are driving, be sure to turn off
accessories such as the radio and climate
control system. Have your vehicle serviced right
away. The SERVICE BATTERY CHARGING
SYSTEM message may also appear in the Driver
Information Center. SeeDIC Warnings and
Messages on page 200for more information.
179
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good
braking, though, you need both parts working well.
If the brake system warning light comes on,
there is a brake problem. Have your brake system
inspected right away.
The brake light is located in the instrument panel
cluster.This light should come on brie y when you turn
the ignition key to RUN. If it does not come
on then, have it xed so it will be ready to warn
you if there is a problem.
When the ignition is on, the brake light will come
on when you set your parking brake. The light
will stay on if your parking brake does not release
fully. A chime will also sound if the parking
brake is not fully released and the vehicle is
moving. If it stays on after your parking brake is
fully released, it means you have a brake problem.
The brake light will also come on to indicate a
low brake uid level. SeeBrakes on page 369for
more information.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice
that the pedal is 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 326.

{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System
Warning Light
With the Anti-Lock
Brake System (ABS),
the light will come
on when your engine is
started and stay on
for several seconds.
This is normal.If the ABS warning light comes on and stays on,
there may be a problem with the anti-lock
portion of the brake system. If the brake system
warning light is not on, you still have brakes,
but you do not have anti-lock brakes. SeeBrake
System Warning Light on page 180for more
information.
If the light stays on, turn the ignition to LOCK. If the
light comes on when you are driving, stop as soon
as possible and turn the ignition off. Then start the
engine again to reset the system. If the light still
stays on, or comes on again while you are driving,
your vehicle needs service. If the regular brake
system warning light is not on, you still have brakes,
but you do not have anti-lock brakes. If the regular
brake system warning light is also on, you do not
have anti-lock brakes and there is a problem with
your regular brakes. SeeBrake System Warning
Light on page 180for more information.
The ABS warning light should come on brie y
when you turn the ignition key to RUN. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.
181
Traction Control System (TCS)
Warning Light
Your vehicle has a
Traction Control
System (TCS) and
StabiliTrak
®warning
light.
This light will come on when the TCS is limiting
wheel spin or when the StabiliTrak
®system
is active. You may feel or hear the system working,
but this is normal.
If the TCS warning light comes on and stays on
for an extended period of time when the system is
turned on, your vehicle needs service. See
Traction Control System (TCS) on page 297and
StabiliTrak
®System on page 298for more
information.
Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light will come on when
the engine has
overheated.
If this happens you should pull over and turn off
the engine as soon as possible. SeeEngine
Overheating on page 360for more information.
Notice:Driving with the engine coolant
temperature warning light on could cause your
vehicle to overheat. SeeEngine Overheating
on page 360. Your vehicle could be damaged,
and it might not be covered by your warranty.
Never drive with the engine coolant
