Radio with a Single CD (Up Level)


Object Number: 988558  Size: B3

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

Radio Data System (RDS) (Up Level)

Your Radio may have 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 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 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 (Up Level)

XM™ is a satellite radio service that is based in the 48 contiguous United States and 10 Canadian provinces. XM™ Satellite Radio has a wide variety of programming and commercial-free music, coast-to-coast, and in digital-quality sound. During your trial or when you subscribe, you will get unlimited access to XM™ Radio Online for when you are not in your vehicle. A service fee is required to receive the XM™ service. For more information, contact XM™ at www.xmradio.com or call 1-800-929-2100 in the U.S. and www.xmradio.ca or call 1-877-438-9677 in Canada.

Playing the Radio

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

(Volume): Turn clockwise or counterclockwise to increase or to decrease the volume.

DISP (Display): Press to switch the display between the time and the temperature or the radio station frequency and the temperature. When the ignition is off, press to display the time. For RDS, press this knob to change what displays while using RDS. The display options are station name, RDS station frequency, PTY, and the name of the program (if available). For XM™ (if equipped), press this 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 DISP knob until the desired option displays, then hold the knob for two seconds. The radio produces a beep and the selected display becomes the default.

AUTO (Automatic Volume) (Up Level): With automatic volume, the audio system adjusts automatically 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. AUTO VOL LOW (automatic volume low), AUTO VOL MEDIUM (automatic volume medium), or AUTO VOL HIGH (automatic volume high) 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. AUTO VOL NONE (automatic volume none) displays if the radio cannot determine the vehicle speed or if the engine is not running. To turn automatic volume off, press this button until AUTO VOL OFF (automatic volume 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.

MSG (Message): If the current station has a message, MSG 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 MSG button. A new group of words display after every press of the button. Once the complete message has displayed, MSG disappears until another new message is received. The last message can be displayed by pressing the MSG button. The last message can be viewed until a new message is received or a different station is tuned to. When a message is not available from a station, NO MESSAGE displays.

TRAF (Traffic): If TRAFFIC displays, the tuned station broadcasts traffic announcements and when a traffic announcement comes on the tuned radio 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 between brackets appears on display. If no station is found that broadcasts traffic announcements, NO TRAFFIC INFO displays. If TRAF is on the display, press the TRAF button to turn off the traffic announcements. The radio plays the traffic announcement even 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

Playing a CD

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

As each new track starts to play, the track number displays.

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.

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-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 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.

CD Messages

If 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 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.
