Radio with Six-Disc CD Player


Object Number: 1536947  Size: B2

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

If your vehicle has the Premium audio system, it includes seven speakers. See your dealer/retailer for details.

The radio has a theft-deterrent feature. A red light blinks while the engine is off to indicate the radio is protected. It will not operate if it is installed in a different vehicle.

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 only works 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 the call letters display instead of the frequency. RDS stations can also provide the time of day, a program type (PTY) for current programming, and the name of the program being broadcast.

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.

RDS Messages

ALERT!: Alert warns of local or national emergencies. When an alert announcement comes on the current radio station, ALERT! displays. You will hear the announcement, 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.

INFO (Information):  If the current station has a message, INFO displays. Press this button to see the message. The message can display the artist, song title, call in phone numbers, etc. If the entire message is not displayed, parts of the message displays every three seconds. To scroll through the message, press and release the INFO button. A new group of words display after every press of this button.

Radio Messages

If any error occurs repeatedly or if an error cannot be corrected, contact your dealer/retailer.

Radio Messages for XM™ Only

See XM Radio Messages later in this section for further detail.

Playing a CD

For the Radio with CD (Base), insert a CD partway into the slot, label side up. The player pulls it in and the CD should begin playing. If you insert a CD with the radio off and the ignition on, it starts to play.

For the Radio with CD (MP3) Insert a CD partway into the slot, label side up. The player pulls it in and READING DISC and the CD symbol displays. If you want to insert a CD with the ignition off, first press the eject button or push the RCL button.

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

When the CD is inserted, 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.

If there is no apparent damage, try a known good CD.

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.

For vehicles that have a radio with a Six-Disc CD player, see the following:

The CD can be removed. If the CD is not removed, after 25 seconds, the CD is automatically pulled back into the player. If the CD is pushed back into the player, before the 25 second time period is complete, the player senses an error and tries to eject the CD several times before stopping. Do not repeatedly press the CD eject button to eject a CD after trying to push it in manually.

CD Messages

CHECK CD: If this message displays and/or the CD comes out, it could be for one of the following reasons:

    • It is very hot. When the temperature returns to normal, the CD should play.
    • You are driving on a very rough road. When the road becomes smoother, the CD should play.
    • The CD is dirty, scratched, wet, or upside down.
    • The air is very humid. If so, wait about an hour and try again.
    • The format of the CD may not be compatible. See Using an MP3 later in this section.
    • There could have been a problem while burning the CD.
    • The label could be caught in the CD player.

If the CD is not playing correctly, for any other reason, try a known good CD.

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.
