Radio with CD MP3


Object Number: 1434153  Size: B3

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
    • 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 could 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 instead of the frequency. RDS stations can also provide the time of day, a program type (PTY) for current programming, and the name of the program being broadcast.

XM™ Satellite Radio Service

XM™ is a satellite radio service that is based in the 48 contiguous United States and Canada. XM™ offers a large variety of coast-to-coast channels including music, news, sports, talk, traffic/weather (U.S. subscribers), and children’s programming. XM™ provides digital quality audio and text information that includes song title and artist name. A service fee is required in order to receive the XM™ service. For more information, contact XM™; In the U.S. at www.xmradio.com or call 1-800-852-XMXM (9696) or in Canada at www.xmradio.ca or call 1-877-GET-XMSR (438-9677).

Playing the Radio

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

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

DISPL (Display): When the ignition is turned off, press this knob to display the time. For RDS, press the DISPL knob to change what displays while using RDS. The display options are station name, RDS station frequency, PTY (program type), and the name of the program (if available). For XM™ (if equipped), press the DISPL knob 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 DISPL knob until you see the desired display, then press and hold this knob for two seconds. The radio produces one beep. The selected display is now the default.

AUTO VOL (Automatic Volume): Automatic volume automatically adjusts the audio system to make up for road and wind noise as you drive. Set the volume at the desired level. Press this button to select LOW, MEDIUM, or HIGH. AVOL displays. Each higher setting allows for more volume compensation at faster vehicle speeds. Then as you drive, automatic volume increases the volume, as necessary, to overcome noise at any speed. The volume level should always sound the same to you as you drive. NONE displays if the radio cannot determine the vehicle speed. To turn automatic volume off, press this button until OFF displays.

RDS Messages

ALERT!: Alert warns of local or national emergencies. When an alert announcement comes on the current radio station, ALERT! displays. You will hear the announcement, even if the volume is low or a CD is playing. If a CD is playing, play stops during the announcement. Alert announcements cannot be turned off. ALERT! is not affected by tests of the emergency broadcast system. This feature is not supported by all RDS stations.

INFO (Information): If the current station has a message, the information symbol displays. Press this button to see the message. The message can display the artist, song title, call in phone numbers, etc. If the entire message is not displayed, parts of the message displays every three seconds. To scroll through the message, press and release the INFO button. A new group of words display after every press of this button. Once the complete message has displayed, the information symbol disappears from the display until another new message is received. The last message can be displayed by pressing the INFO button. The last message stays on the display until a new message is received or the radio is tuned to a different station. When a message is not available from a station, NO INFO displays.

TRAF (Traffic): If TRAF displays, the tuned station broadcasts traffic announcements. When a traffic announcement is broadcast on this station you will hear it. If the station does not broadcast traffic announcements, press the TRAF button and the radio seeks to a station that does. When a station that broadcasts traffic announcements is found, the radio stops seeking and TRAF displays. If no station is found that broadcasts traffic announcements, NO TRAF displays. If TRAF displays, press the TRAF button to turn off the traffic announcements. The radio plays the traffic announcement if the volume is low. The radio interrupts the play of a CD if the last tuned station broadcasts traffic announcements. This function does not apply to XM™ Satellite Radio Service.

Radio Messages

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

LOCKED: This message displays when the THEFTLOCK® system has locked up. Take your vehicle to your dealer/retailer for service. If any error occurs repeatedly or if an error cannot be corrected, contact your dealer/retailer.

Radio Messages for XM™ Only

Playing a CD

Insert a CD partway into the slot, label side up. The player pulls it in, and READING displays. The CD should begin playing. If you want to insert a CD with the ignition off, first press the (eject) button or the DISPL knob.

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 to play where it stopped, if it was the last selected audio source.

When the CD is inserted, the CD symbol displays. As each new track starts to play, the track number displays.

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 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. There can 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 does 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 displays, see "CD Messages" later in this section.

Playing an MP3/WMA CD-R Disc

Your vehicle's radio system may have the MP3/WMA feature. If it has this feature, it is capable of playing an MP3/WMA CD-R disc. For more information on how to play an MP3/WMA CD-R disc, see Using an MP3 later in this section.

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.
    • 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.
    • The format of the CD might not be compatible. See Using an MP3 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.
