OnStar Virtual Advisor
OnStar Virtual Advisor is a feature of OnStar
Hands-Free Calling that uses minutes to access
location-based weather, local traffic reports, and stock
quotes. Press the phone button and give a few simple
voice commands to browse through the various topics.
See the OnStar Owner’s Guide for more information.
This feature is only available in the continental U.S.
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 wherethe 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.

Sunshade Operation
The sunshade will open automatically when opening the
sunroof.
However, it can manually be pulled shut after the
sunroof is closed. To adjust the sunshade, push it
backward or pull it forward to the desired position.
The sunshade cannot be adjusted further than
the current closed position of the sunroof.
Notice:If you force the sunshade forward of the
sliding glass panel, damage will occur and the
sunroof may not open or close properly. Always
close the glass panel before closing the sunshade.
Do not leave the sunroof open for long periods of
time. Debris can collect in the tracks and possibly
damage the sunroof operation and plug the water
draining system.
Retractable Hardtop
The following procedures explain the proper operation
of the retractable hardtop. The retractable hardtop
will not operate if the trunk cargo cover is not in place.
If the retractable hardtop is lowered or raised multiple
times, the engine should be running while doing
so to prevent drain on the vehicle’s battery.
Lowering the Retractable Hardtop
Notice:Leaving the retractable hardtop down and
exposing the interior of the vehicle to outdoor
conditions may cause damage. Always close the
retractable hardtop if leaving the vehicle outdoors.
Notice:Lowering the top if it is damp, wet, or
dirty can cause stains, mildew, and damage to
the inside of your vehicle. Dry off the top before
lowering it.
Notice:If you lower the retractable hardtop in cold
weather (32°F/0°C or lower), you may damage top
components. Do not lower the retractable hardtop
in cold weather.
1. Park on a level surface, and shift the transmission
into (P) Park. The vehicle must be in (P) Park, and
the engine must be running, or the ignition turned
to the ON/RUN position, to operate the retractable
hardtop.

Parade Dimming
Parade mode automatically prohibits the dimming of the
instrument panel displays during the daylight while
the headlamps are on so that the displays are still able
to be seen.
Reading Lamps
For vehicles with front and rear reading lamps, press
the lens to turn the lamp on and off, while the doors are
closed. These lamps come on automatically when
any door is opened.
Trunk Lamp
The trunk lamp comes on when the trunk is opened and
turns off when the trunk is closed.
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 bring the charge back
up. 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.
3-17

A high electrical load occurs when several of the
following are on, such as: 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, BATTERY VOLTAGE LOW, or
LOW BATTERY. 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 3-46.Battery Run-Down Protection
The battery run-down feature is designed to protect the
vehicle’s battery.
When any interior lamp (trunk, reading lamps, or dome
lamp) is left on when the ignition is turned off, the
battery run-down protection system automatically shuts
the lamp off after 20 minutes. This prevents draining
of the battery.
To reactivate the interior lamps, do one of the following:
Open any door.
Press any Remote Keyless Entry (RKE) transmitter
button.
Press the power door lock switch.
Press the remote trunk release.
Turn the lamp that was left on to off and then to
on again.
3-18

Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone or CB radio.
There are two accessory power outlets, located on the
center console below the climate controls. If the
vehicle has a Traction Control System (TCS), one
accessory power outlet is in the center storage console
and the other is on the center console below the
climate controls.
To use an outlet, remove the protective cap. When not
in use, always cover the outlet with the protective cap.
The accessory power outlet is operational at all times.
Notice:If electrical devices are left plugged
into a power outlet, the battery may drain causing
the 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 the vehicle.Certain electrical accessories are not compatible with
the accessory power outlet 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 the
vehicle can damage it or keep other components
from working as they should. The repairs would not
be covered by the vehicle 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 proper installation instructions included with
the equipment.
Notice:Improper use of the power outlet can cause
damage not covered by the 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 the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if the
key is in ON/RUN and the light is not on.
The vehicle will not pass this inspection if the
OBD II (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 the battery has recently been
replaced 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 this has been done and the vehicle still does not
pass the inspection for lack of OBD II 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.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
