How OnStar Service Works
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.Location information about your vehicle is only available
if the GPS satellite signals are unobstructed and
available.
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
Increase the radio volume if you cannot 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 your dealer/retailer. 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.

Cargo Lamp
The cargo lamp is located over the rear compartment,
and is controlled by the dome lamp. SeeDome Lamp on
page 3-17.
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 a 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 3-52.
3-18
Battery Run-Down Protection
Your vehicle has a battery saver feature designed to
protect the vehicle’s battery.
When any interior lamp is left on and the ignition is
turned off, the battery rundown protection system will
automatically turn the lamp off after 20 minutes. This will
avoid draining the battery. This vehicle also has a
retained accessory power feature. If the radio is on, it
will turn off after 10 minutes or if any door on the vehicle
is opened. SeeRetained Accessory Power (RAP) on
page 2-22.
Accessory Power Outlet(s)
The accessory power outlets can be used to connect
electrical equipment such as a cellular phone or
CB radio.
The two accessory power outlets are located in the front
and at the rear of the center console storage area.
To use the outlets, remove the cover. When not in use,
always cover the outlet with the protective cap.Notice:If electrical devices are left plugged into a
power outlet, the battery may drain causing your
vehicle not to start or damage to the battery.
This would not be covered by the warranty. Always
unplug all electrical devices when turning off
your vehicle.
Certain electrical accessories may not be compatible
with the accessory power outlets and could result
in blown vehicle or adapter fuses. If you experience a
problem, see your dealer/retailer for additional
information on the accessory power outlet.
Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating of 20 amperes.
Check with your dealer/retailer before adding
electrical equipment.
When adding electrical equipment, be sure to follow the
installation instructions included with the equipment.
Notice:Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the check
engine light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced the battery or if the battery
has run down. The diagnostic system is designed to
evaluate critical emission control systems during normal
driving. This can take several days of routine driving. If
you have done this and your vehicle still does not pass
the inspection for lack of OBD system readiness, your
dealer/retailer can prepare the vehicle for inspection.
Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.
This light will come on
brie y when you start your
engine. If it does not,
have your vehicle serviced.
3-39
Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
It cannot be reset accurately until the next oil change.
To reset the engine oil life system, seeEngine Oil
Life System on page 5-18.
UNITS
Press the vehicle information button until UNITS
displays. This display allows you to select between
English or Metric units of measurement. Once in this
display, press the set/reset button to select between
ENGLISH or METRIC units.
FRONT TIRES or REAR TIRES
The pressure for each tire can be viewed in the DIC.
The tire pressure will be shown in either pounds per
square inch (psi) or kilopascals (kPa). Press the vehicle
information button until the DIC displays FRONT TIRES
PSI (kPa) LF ## RF ##. Press the vehicle information
button again until the DIC displays REAR TIRES
PSI (kPa) LR ## RR ##.If a low or high tire pressure condition is detected by
the system while driving, a message advising you
to check the pressure in a speci c tire will appear in
the display. SeeInflation - Tire Pressure on page 5-59
andDIC Warnings and Messages on page 3-52for
more information.
If the tire pressure display shows dashes instead of
a value, there may be a problem with your vehicle. If this
consistently occurs, see your dealer/retailer for service.
BATTERY
Press the vehicle information button until BATTERY
displays. This display shows the current battery voltage.
If the voltage is normal, the display will show NORMAL.
If the voltage is low or high, the display will show
LOW or HIGH. Your vehicle’s charging system regulates
voltage based on the state of the battery. The battery
voltage may uctuate when viewing this information
on the DIC. This is normal. SeeCharging System Light
on page 3-32for more information.
If there is a problem with the battery charging system,
the DIC will display SERVICE BATTERY CHARGING
SYSTEM. See “SERVICE BATTERY CHARGING
SYSTEM” underDIC Warnings and Messages on
page 3-52. Also, seeElectric Power Management
on page 3-18for more information.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that
some action may be needed by the driver to correct
the condition. Multiple messages may appear one after
another.
Some messages may not require immediate action,
but you can press the set/reset button to acknowledge
that you received the messages and to clear them
from the display. Pressing any of the DIC buttons
also acknowledge and clear any messages.
Some messages cannot be cleared from the DIC
display because they are more urgent. These messages
require action before they can be cleared. You should
take any messages that appear on the display seriously
and remember that clearing the messages will only
make the messages disappear, not correct the problem.
The following are the possible messages that can be
displayed and some information about them.
ALL WHEEL DRIVE OFF
If your vehicle has the All-Wheel Drive (AWD) system,
this message displays along with the All-Wheel Drive
Disabled light when the rear drive system is overheating.
