Radio Data System (RDS)

The audio system has a Radio Data System (RDS). The RDS feature 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 could 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.

Speed Compensated Volume (SCV): Radios with Speed Compensated Volume (SCV) automatically adjusts radio volume to compensate for road and wind noise as driving speed changes. 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 (volume) label on the radio display.
  4. Press the pushbutton under the desired Speed Compensated Volume setting (OFF, Low, Med (medium), 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.

Finding a Station

BAND: Press to switch between AM, FM, or XM™. 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 three 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 scan stations with a strong signal that are in the selected band.

(Information) (XM Satellite Radio Service, MP3/WMA, and RDS Features): Press to simultaneously display the Channel Number, Song Title, and Artist information while in XM mode. Press to display additional text information related to the current FM-RDS, or MP3/WMA song, if available. When 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 stopped. Tune to your favorite stations using the presets, favorites button, and steering wheel controls, if your 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. 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, FM, or XM 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 you want the station 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 you want stored as a favorite.

The number of favorites pages can be setup using the MENU button. To setup the number of favorites pages:

  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.
  4. Press the FAV button, or let the menu time out, to return to the original main radio screen showing the radio station frequency labels and to begin the process of programming your favorites for the chosen amount of numbered pages.

Setting the Tone (Bass/Midrange/Treble)

BASS/MID/TREB (Bass, Midrange, or Treble): To adjust bass, midrange, or treble, press the knob until the tone control labels display. Continue pressing to highlight the desired label, or press the pushbutton positioned under the desired label. Turn this knob clockwise or counterclockwise to adjust the highlighted setting. The highlighted setting can also be adjusted by pressing either SEEK arrow, FWD, or REV button until the desired levels are obtained. If a station's frequency is weak, or if there is static, decrease the treble. To quickly adjust bass, midrange, or treble to the middle position, press the knob for more than two seconds. A beep sounds and the level adjusts to the middle position. Pressing this knob for more than two seconds also centers the fade and balance settings to the factory default positions.

Finding a Category (CAT) Station

CAT (Category): The CAT button is used to find XM stations when the radio is in the XM mode. To find XM channels within a desired category:

  1. Press the BAND button until the XM frequency displays. Press the CAT button to display the category labels on the radio display. Continue pressing the CAT button until the desired category name displays.
  2. Press either of the two buttons below the desired category label to immediately tune to the first XM station associated with that category.
  3. Turn the knob, press the buttons below the right or left arrows displayed, or press either SEEK arrow to go to the previous or to the next XM station within the selected category.
  4. To exit the category search mode, press the FAV button or BAND button to display your favorites again.

Undesired XM categories can be removed through the setup menu. To remove an undesired category:

  1. Press the MENU button to display the radio setup menu.
  2. Press the pushbutton located below the XM CAT label.
  3. Turn the knob to display the category you want removed.
  4. Press the pushbutton located under the Remove label until the category name along with the word Removed displays.
  5. Repeat the steps to remove more categories.

Removed categories can be restored by pressing the pushbutton under the Add label when a removed category displays or by pressing the pushbutton under the Restore All label.

The radio does not let you remove or add categories while the vehicle is moving faster than 5 mph (8 km/h).

The CAT button also toggles between compressed and uncompressed audio when a mixed disc is present. See "Compressed Audio" later in this section.

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 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/WMA CD-R or CD-RW Disc

Radios with the MP3 feature are capable of playing an MP3/WMA CD-R or CD-RW disc. For more information on how to play an MP3/WMA CD-R or CD-RW disc, see Using an MP3 later in this section.

CD Messages

DISC ERROR: If an error message displays and/or the CD comes out, it could be for one of the following reasons:

    • The radio system does not support the playlist format, the compressed audio format, or the data file format.
    • 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.
    • There could have been a problem while burning the CD.
    • The label could be caught in the CD player.

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.

Using the Auxiliary Input Jack

The radio system has an auxiliary input jack located on the lower right side of the faceplate. This is not an audio output; do not plug the headphone set into the front auxiliary input jack. Connect an external audio device such as an iPod, laptop computer, MP3 player, CD changer, or cassette tape player, etc. to the auxiliary input jack for use as another source for audio listening.

Drivers are encouraged to set up any auxiliary device while the vehicle is in P (Park). See Defensive Driving for more information on driver distraction.

To use a portable audio player, connect a 3.5 mm (1/8 inch) cable to the radio's front auxiliary input jack. When a device is connected, press the radio CD/AUX button to begin playing audio from the device over the vehicle speakers.

(Power/Volume): Turn clockwise or counterclockwise to increase or decrease the volume of the portable player. You might need to do additional volume adjustments from the portable device if the volume is not loud or soft enough.
