Object Number: 1546891  Size: B3

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

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
    • 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 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

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

Speed Compensated Volume (SCV): The radio has Speed Compensated Volume (SCV). When SCV is on, the radio volume automatically adjusts to compensate for road and wind noise as the vehicle speeds up or slows down. 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 MENU button to display the radio setup menu.
  3. Press the pushbutton under the AUTO VOLUM (automatic volume) label on the radio display.
  4. Press the pushbutton under the desired SCV setting (OFF, Low, Med, or High) to select the level of radio volume compensation. Each higher setting allows for more radio volume compensation at faster vehicle speeds. The display times out after approximately 10 seconds.

Finding a Station

BAND: Press to switch between AM or FM. The display shows the selection.

(Tune): Turn to select radio stations.

SEEK : Press the arrows to go to the previous or to the next station and stay there. To scan stations, press and hold either arrow for a few seconds until a beep sounds. The radio goes to a station, plays for a few seconds, then goes to the next station. Press either arrow again to stop scanning. The radio only seeks and scans stations with a strong signal that are in the selected band.

(Information) (MP3 and RDS Features): Press to display additional text information related to the current FM-RDS or MP3 song. A choice of additional information such as: Channel, Song, Artist, and CAT (category) can appear. Continue pressing to highlight the desired label, or press the pushbutton positioned under any one of the labels and the information about that label displays. While information is not available, No Info displays.

Storing a Radio Station as a Favorite

Drivers are encouraged to set up their radio station favorites while the vehicle is parked. Tune to your favorite stations using the presets, favorites button, and steering wheel controls if the vehicle has this feature. See Defensive Driving .

FAV (Favorites): A maximum of 36 stations can be programmed as favorites using the six pushbuttons positioned below the radio station frequency labels and by using the radio favorites page button (FAV button). Press the FAV button to go through up to six pages of favorites, each having six favorite stations available per page. Each page of favorites can contain any combination of AM or FM stations. To store a station as a favorite, perform the following steps:

  1. Tune to the desired radio station.
  2. Press the FAV button to display the page where the station is to be stored.
  3. Press and hold one of the six pushbuttons until a beep sounds. When that pushbutton is pressed and released, the station that was set, returns.
  4. Repeat the steps for each pushbutton radio station to be stored as a favorite.

The number of favorites pages can be setup using the MENU button. To setup the number of favorites pages, perform the following steps:

  1. Press the MENU button to display the radio setup menu.
  2. Press the pushbutton located below the FAV 1-6 label.
  3. Select the desired number of favorites pages by pressing the pushbutton located below the displayed page numbers.

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, the 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 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.
