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

Radio Data System (RDS)

The radio may have the Radio Data System (RDS) feature. RDS is available for use only on FM stations that broadcast RDS information. This system relies upon receiving specific 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

(Power/Volume): Press to turn the system on and off. Turn clockwise or counterclockwise to increase or decrease the volume. The radio goes to the previous volume setting when the radio is turned on. The volume can still be adjusted by using the volume knob.

Speed Compensated Volume (SCV): SCV automatically adjusts the radio volume to compensate for road and wind noise as the vehicle increases or decreases speed while driving. The volume level should sound about the same while driving. To activate SCV:

  1. Set the radio volume to the desired level.
  2. Press the MENU button to display the radio setup menu.
  3. Press the pushbutton under the AUTO VOLUM (automatic volume) tab 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.

Care of 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 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.

Playing an MP3 CD-R or CD-RW Disc

The radio may have MP3 CD-R or CD-RW disc capability. For more information, see Using an MP3 later in this section.

CD Messages

CHECK DISC: If an error 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.
    • There could have been a problem while burning the CD.
    • The label could be caught in the CD player.

If there is no apparent damage, 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 while reporting the problem.

Using the Auxiliary Input Jack
