Your vehicle has one of these radios as its audio system.

An indicator light on the upper left side of the radio flashes when the ignition is off, to indicate the theft deterrent feature is set. For more information, see Theft-Deterrent Feature .

Your vehicle has seven Bose® amplified speakers. See your dealer/retailer for details.

Radio Data System (RDS)

The audio system has a Radio Data System (RDS). RDS features are available for use only on FM stations that broadcast RDS information.

With RDS, the radio can do the following:

    • Seek to stations broadcasting the selected type of programming.
    • Receive announcements concerning local and national emergencies.
    • Display messages from radio stations.
    • Seek to stations with traffic announcements.

This system relies upon receiving specific information from these stations and works only when the information is available. 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.

While the radio is tuned to an RDS station, the station name or call letters display. RDS stations can also provide the time of day, a program type (PTY) for current programming, and the name of the program being broadcast.

Playing the Radio

Top Knob (Power/Volume): Press to turn the system on and off. Turn clockwise or counterclockwise to increase or decrease the volume.

(Information): For RDS, press to change what display while using RDS. The display options are station name, RDS station frequency, PTY, and the name of the program (if available). For XM™ (if equipped), press while in XM™ mode to retrieve four different categories of information related to the current song or channel: Artist, Song Title, Category or PTY, Channel Number/Channel Name. To change the default on the display, press until you see the desired display, then hold for two seconds. The radio produces one beep and the selected display is now the default.

AUTO (Automatic Volume): Automatic volume automatically adjusts the audio system to make up for road and wind noise as you drive, by increasing the volume as vehicle speed increases. Set the volume at the desired level. Press this button to select AUTO VOLUME MIN (minimum), AUTO VOLUME MED (medium), or AUTO VOLUME MAX (maximum). Each higher setting provides more volume compensation at faster vehicle speeds. To turn automatic volume off, press this until AUTO VOLUME OFF displays. If your vehicle has the Bose® sound system, it includes Bose® AudioPilot® noise compensation technology. When turned on, AudioPilot® continuously adjusts the audio system equalization to compensate for background noise, so that the music always sounds the same at the set volume level. This feature is most effective at lower radio volume settings where background noise can affect how well you hear the music being played. At higher volume settings, where the music is much louder than the background noise, there could be little or no adjustments by AudioPilot®. To use AudioPilot®, set the radio volume to the desired level. Turn AudioPilot® on by pressing the automatic volume button until AVOL ON displays. As the vehicle goes faster, the background noise increases. AudioPilot® adjusts the audio system's equalization to overcome background noise. To turn AudioPilot® off, press the automatic volume button until AVOL OFF displays. For additional information on AudioPilot®, visit www.bose.com/audiopilot.

MUTE: Press to silence the system. Press again to turn the sound on. This button is not available on the Radio with Six-Disc CD.

RDS Messages

ALERT!: Alert warns of local or national emergencies. When an alert announcement comes on the current radio station, ALERT! displays. The announcement is heard, even if the volume is low or a CD is playing. If a CD is playing, play stops during the announcement. Alert announcements cannot be turned off. ALERT! is not affected by tests of the emergency broadcast system. This feature is not supported by all RDS stations.

(Information): If the current station has a message, INFO (information) displays. Press to see the message.

If the station does not broadcast traffic announcements, press the TRAF button and the radio seeks to a station that does. When a station that broadcasts traffic announcements is found, the radio stops seeking and TA displays. If no station is found that broadcasts traffic announcements, NO TRAFFIC INFO displays. If TA is on the display, press the TRAF button to turn off the traffic announcements. The radio plays the traffic announcement even if the volume is low. The radio interrupts the play of a CD if the last tuned station broadcasts traffic announcements. This function does not apply to XM™ Satellite Radio Service.

Radio Messages

LOCKED: This message displays when the THEFTLOCK® system has locked up. Take the vehicle to your dealer/retailer for service.

If any error occurs repeatedly or if an error cannot be corrected, contact your dealer/retailer. If the radio displays an error message, write it down and provide it to your dealer/retailer when reporting the problem.

XM™ Satellite Radio Service

XM™ is a satellite radio service that is based in the 48 contiguous United States and 10 Canadian provinces. XM™ Satellite Radio has a wide variety of programming and commercial-free music, coast-to-coast, and in digital-quality sound. During your trial or when you subscribe, you will get unlimited access to XM™ Radio Online for when you are not in your vehicle. A service fee is required to receive the XM™ service. For more information, contact XM™ at www.xmradio.com or call 1-800-929-2100 in the U.S. and www.xmradio.ca or call 1-877-438-9677 in Canada.

XM™ Radio Messages

With XM™ Satellite Radio Service, the radio can display screen messages pertaining to the XM™ radio service, software and hardware. See XM Radio Messages later in this section for further detail.

Playing a CD (Single CD Player)

Insert a CD partway into the slot, label side up. The player pulls it in and the CD should begin playing if the radio is on, or if the radio is off and the vehicle is running or in accessory mode.

If the ignition or radio is turned off with a CD in the player, it stays in the player. When the ignition or radio is turned on, the CD starts playing where it stopped, if it was the last selected audio source.

When a CD is inserted, CD and the CD symbol displays. As each new track starts to play, the track number displays.

The CD player can play the smaller 3 inch (8 cm) single CDs with an adapter ring. Full-size CDs and the smaller CDs are loaded in the same manner.

Care of Your CDs

If playing a CD-R, the sound quality can be reduced due to CD-R quality, the method of recording, the quality of the music that has been recorded, and the way the CD-R has been handled. Handle them carefully. Store CD-R(s) in their original cases or other protective cases and away from direct sunlight and dust. The CD player scans the bottom surface of the disc. If the surface of a CD is damaged, such as cracked, broken, or scratched, the CD does not play properly or not at all. Do not touch the bottom side of a CD while handling it; this could damage the surface. Pick up CDs by grasping the outer edges or the edge of the hole and the outer edge.

If the surface of a CD is soiled, take a soft, lint free cloth or dampen a clean, soft cloth in a mild, neutral detergent solution mixed with water, and clean it. Make sure the wiping process starts from the center to the edge.

Care of Your CD Player

Do not add any label to a CD, it could get caught in the CD player. If a CD is recorded on a personal computer and a description label is needed, try labeling the top of the recorded CD with a marking pen.

The use of CD lens cleaners for CDs is not advised, due to the risk of contaminating the lens of the CD optics with lubricants internal to the CD player mechanism.

Notice: If a label is added to a CD, or more than one CD is inserted into the slot at a time, or an attempt is made to play scratched or damaged CDs, the CD player could be damaged. While using the CD player, use only CDs in good condition without any label, load one CD at a time, and keep the CD player and the loading slot free of foreign materials, liquids, and debris.

If an error displays, see "CD Messages" later in this section.

Playing a CD(s) (Six-Disc CD Player)

If the ignition or radio is turned off, with a CD in the player, it stays in the player. When the ignition or radio is turned on, the CD starts playing where it stopped, if it was the last selected audio source.

When a CD is inserted, the CD symbol appears on the CD. As each new track starts to play, the track number displays.
