Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Power Windows
Sunroof (if equipped)
Power to the audio system will work up to 10 minutes or
until the driver’s door is opened. Power to the windows
or sunroof will work up to 10 minutes or until any
door is opened. For an additional 10 minutes of
operation, close all the doors and turn the key to
ON/RUN and then back to LOCK/OFF.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move the shift lever to PARK (P) or NEUTRAL (N).
The engine will not start in any other position -- this
is a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.If your vehicle has the keyless access system, put your
foot on the brake pedal and turn the ignition control
knob to the START position. When the engine begins
cranking, let go of the ignition control knob, it will return
to the ON/RUN position.
If the transmitter is not in the vehicle or something is
interfering with the transmitter, the Driver Information
Center (DIC) will display Electronic Key Not Detected.
SeeDIC Warnings and Messages on page 3-56for
more information.
If the battery in the keyless access transmitter needs
replacing, the DIC displays Replace Battery In Remote
Key. The vehicle can still be driven. See “Battery
Replacement” underKeyless Access System Operation
on page 2-10for more information.
Notice:Do not try to shift to P (Park) if your
vehicle is moving. If you do, you could damage
the transmission. Shift to P (Park) only when your
vehicle is stopped.

OnStar Steering Wheel Controls
Your vehicle may have a Talk/Mute button that can
be used to interact with OnStar Hands-Free Calling.
SeeAudio Steering Wheel Controls on page 3-124for
more information.
On some vehicles, you may have to hold the button for
a few seconds and give the command “ONSTAR” to
activate the OnStar Hands-Free Calling.
On some vehicles, the mute button can be used to
dial numbers into voicemail systems, or to dial phone
extensions. See the OnStar Owner’s Guide for
more information.
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.

Audio System(s)
Determine which radio your vehicle has and then read
the pages following to familiarize yourself with its
features.
{CAUTION:
This system provides you with far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and you
or others can be injured or killed. Always keep
your eyes on the road and your mind on the
drive — avoid engaging in extended searching
while driving.
Keeping your mind on the drive is important for safe
driving. SeeDefensive Driving on page 4-2. Here are
some ways in which you can help avoid distraction
while driving.While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
Set up your audio system by presetting your
favorite radio stations, setting the tone, and
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering wheel
controls if the vehicle has them.
Notice:Before adding any sound equipment to
your vehicle, such as an audio system, CD player,
CB radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer/retailer. Also, check federal rules covering
mobile radio and telephone units. If sound equipment
can be added, it is very important to do it properly.
Added sound equipment may interfere with the
operation of your vehicle’s engine, radio, or other
systems, and even damage them. Your vehicle’s
systems may interfere with the operation of sound
equipment that has been added.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. SeeRetained
Accessory Power (RAP) on page 2-35for more
information.

Radio(s)
Your vehicle may have one of these radios as its
audio system.
If your vehicle does not have one of these radio
systems, it may have a navigation radio system.
See the Navigation System manual for more information
on the navigation audio system.
If your vehicle has one of these radios, it has either a
Bose
®sound system or a Bose®5.1 Cabin Surround®
sound system. See “Digital Signal Processing (DSP)”
later in this section for more information on the Bose®
5.1 Cabin Surround®sound system. Full View of Radio with CD shown, Radio with
Six-Disc CD similar
Partial View of Radio with DVD Audio, Hard Drive
Device (HDD), and USB
3-83
The radio with DVD Audio, HDD, and USB utilizes
Gracenote®technology to provide Song, Artist, Album,
and Genre information for many CD audio discs
and is capable of playing DVD-A and DTS encoded
discs, (DTS and DTS Digital Surround are registered
trademarks of Digital Theater Systems, Inc.).
Manufactured under license from Dolby Laboratories.
Dolby and the double-D symbol are trademarks of Dolby
Laboratories.
Radio Data System (RDS)
The audio system has a Radio Data System (RDS)
feature. RDS is available for use only on FM stations
that broadcast RDS information. This system relies upon
receiving speci c information from these stations and
only works when the information is available. While
the radio is tuned to an FM-RDS station, the station
name or call letters display. In rare cases, a radio station
can broadcast incorrect information that causes the
radio features to work improperly. If this happens,
contact the radio station.
Playing the Radio
VOLP(Volume/Power):The power knob is part of
the VOL (volume) knob and is located above the radio,
at the left side of the clock. Press to turn the system
on and off.
Turn the VOL knob clockwise or counterclockwise to
increase or decrease the volume.
Speed Compensated Volume (SCV):A Radio with
Speed Compensated Volume (SCV) automatically
adjusts the sound to compensate for road and wind
noise as the vehicle speeds up or slows down, so that
the volume is consistent while driving. That way,
the volume level should sound about the same as
you drive. To activate SCV:
1. Set the radio volume to the desired level.
2. Press the CONFIG button to display the radio
setup menu.
3. Press the pushbutton under the AUTO VOL
(automatic volume) label on the radio display.
4. Press the pushbutton under the desired Speed
Compensated Volume setting (OFF, Low, Med,
or High) to select the level of radio volume
compensation. The display times out after
approximately 10 seconds. Each higher setting
allows for more radio volume compensation at
faster vehicle speeds.
