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

This system relies upon receiving specific information from these stations and only works when the information is available. In rare cases, a radio station may 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 appear on the display instead of the frequency. RDS stations may also provide the time of day, a program type (PTY) for current programming, and the name of the program being broadcast.

Finding a Program Type (PTY) Station

To select and find a desired PTY perform the following:

  1. Press the TYPE button to activate program type select mode. P-TYPE and the last selected PTY appears on the display.
  2. Turn the TYPE knob or press and release the TYPE button to select a PTY.
  3. Once the desired PTY is displayed, press either the TYPE or the SEEK arrows to select and to take you to the PTY's first station.
  4. To cancel the seek, press any of the TYPE or SEEK arrows. This also exits the program type seek mode and returns to the last tuned station.
SCAN: Scan the stations within a PTY by performing the following:

  1. Press the TYPE button to activate program type select mode. P-TYPE and the last selected PTY appears on the display.
  2. Turn the TYPE knob or press and release the TYPE button to select a PTY.
  3. Once the desired PTY is displayed, press and hold either the TYPE or the SCAN arrows for two seconds, and the radio begins scanning the stations in the PTY.
  4. Press either the TYPE or the SCAN arrows to stop scanning.
BAND (Alternate Frequency): Alternate frequency allows the radio to switch to a stronger station with the same program type. To turn alternate frequency on, press and hold BAND for two seconds. AF ON appears on the display. The radio may switch to stations with a stronger frequency. To turn alternate frequency off, press and hold BAND again for two seconds. AF OFF appears on the display. The radio does not switch to other stations.

Setting Preset PTYs (RDS Only)

These pushbuttons have factory PTY presets. Up to 12 PTYs (six FM1 and six FM2), can be programmed on the six numbered pushbuttons, by performing the following steps:

  1. Press BAND to select FM1 or FM2.
  2. Press the TYPE button to activate program type select mode. P-TYPE and the last selected PTY appears on the display.
  3. Turn the TYPE knob or press and release the TYPE button to select a PTY.
  4. Press and hold one of the six numbered pushbuttons until you hear a beep. Whenever that numbered pushbutton is pressed, the PTY that was set returns.
  5. Repeat the steps for each pushbutton.

RDS Messages

INFO (Information): If the current station has a message, INFO appears on the display. Press this button to see the message. The message may display the artist, song title, call in phone numbers, etc. If the entire message is not displayed, parts of the message appears every three seconds. To scroll through the message, press and release the INFO button. A new group of words appears on the display after every press of this button. Once the complete message has been displayed, INFO disappears from the display until another new message is received. The last message can be displayed by pressing the INFO button. You can view the last message until a new message is received or a different station is tuned to.

Radio Messages

CAL ERR (Calibration Error): The audio system has been calibrated for your vehicle from the factory. If CAL ERR appears on the display, it means that the radio has not been configured properly for the vehicle and must be returned to your dealer for service.

LOCKED: This message is displayed when the THEFTLOCK® system has locked up. Take the vehicle to your dealer for service.

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

Playing a CD

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

When a CD is inserted, the CD symbol appears on the display. As each new track starts to play, the track number appears on the display.

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.

If playing a CD-R, the sound quality may 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. There may be an increase in skipping, difficulty in finding tracks, and/or difficulty in loading and ejecting. If these problems occur, check the bottom surface of the CD. If the surface of the CD is damaged, such as cracked, broken, or scratched, the CD will not play properly. If the surface of the CD is soiled, see Care of Your CDs for more information.

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

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.

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 appears on the display, see "CD Messages" later in this section.

LOAD: Press this button to load CDs into the CD player. This CD player holds up to six CDs.

To insert one CD, do the following:

  1. Turn the ignition on.
  2. Press and release the LOAD button.
  3. Wait for the indicator light, located to the right of the slot, to turn green.
  4. Load a CD. Insert the CD partway into the slot, label side up. The player pulls the CD in.

To insert multiple CDs, do the following:

  1. Turn the ignition on.
  2. Press and hold the LOAD button for two seconds.
  3. You will hear a beep and the indicator light, located to the right of the slot, begins to flash and MULTI LOAD # appears on the display.

  4. Once the light stops flashing and turns green, INSERT CD # appears on the display, load a CD. Insert the CD partway into the slot, label side up. The player pulls the CD in.
  5. Once the CD is loaded, the indicator light begins flashing again. Once the light stops flashing and turns green, you can load another CD. The CD player takes up to six CDs. Do not try to load more than six.

To load more than one CD but less than six, complete Steps 1 through 3. When finished loading CDs, press the LOAD button to cancel the loading function. The radio begins to play the last CD loaded.

If more than one CD has been loaded, a number for each CD appears on the display.

Playing a Specific Loaded CD

For every CD loaded, a number appears on the display. To play a specific CD, first press the CD AUX button (if not already in CD mode), then press the numbered pushbutton that corresponds to the CD. A small bar appears under the CD number that is playing and the track number appears on the display.

If an error appears on the display, see "CD Messages" later in this section.

CD (Eject): Press this button to eject CD(s).

To eject the CD that is currently playing, press and release this button.

To eject multiple CDs, do the following:

  1. Press and hold the CD eject button for five seconds.
  2. You will hear a beep and the indicator light, located to the right of the slot, begins to flash and EJECT ALL appears on the display.

  3. Once the light stops flashing, REMOVE CD # appears on the display. The CD ejects and can be removed.
  4. Once the CD is removed, the indicator light begins flashing again and another CD ejects.

    To stop ejecting the CDs, press the LOAD or the eject button.

If the CD is not removed, after 25 seconds, the CD automatically pulls back into the player. If 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 you have tried to push it in manually. The player's 25-second eject timer resets at each press of eject, causing the player to not eject the CD until the 25-second time period has elapsed.

CD Messages

CHECK CD:  If this message appears on the display 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.
    • There may have been a problem while burning the CD.
    • The label may 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. If the radio displays an error message, write it down and provide it to your dealer when reporting the problem.
