Radio with Six-Disc CD


Object Number: 1442146  Size: B3

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

Playing the Radio

(Power): Press to turn the system on and off.

(Volume): Turn to increase or to decrease the volume.

DISP (Display): Press to switch the display between the radio station frequency and time of day. While the ignition is off, press this button to display the time. If the vehicle’s radio has XM™, press the DISP button 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 the DISP button until the desired display appears, then hold DISP for two seconds. The radio beeps once and the selected display becomes the default.

SCV (Speed Compensated Volume): If the vehicle’s radio has Speed Compensated Volume (SCV), the audio system adjusts automatically to make up for road and wind noise while driving. Set the volume at the desired level. Press this button to select LOW, MEDIUM, or HIGH. Depending on the radio, the selection may be SPEED VOL MIN (volume minimum), SPEED VOL MED (volume medium), or SPEED VOL MAX (volume maximum). Each higher setting allows for more volume compensation at faster vehicle speeds. Then while driving, SCV increases the volume, as necessary, to overcome noise at any speed. The volume level should always sound the same while driving. NONE displays if the radio cannot determine the vehicle speed. To turn SCV off, press SCV until OFF or SPEED VOL OFF displays.

Using List Mode

The Six-Disc CD player has a feature called song list. This feature is capable of saving 20 track selections.

If a CD is ejected, and the song list contains saved tracks from that CD, those tracks are automatically deleted from the song list. Any tracks saved to the song list again are added to the bottom of the list.

To end song list mode, press the LIST button. The radio beeps once and LIST is removed from the display.

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.
    • The road is very rough. 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 might not be compatible. Depending on the radio, see "MP3 Format" 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.

Care of CDs

CD sound quality can be reduced due to CD quality, the method of recording, the quality of the music that has been recorded, and the way the CD has been handled. Handle them carefully. Store CD(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 the 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.
