Object Number: 1951067  Size: B3

Radio with a Six-Disc CD Player


Object Number: 1862565  Size: B3

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

If the vehicle has the Monsoon audio system, it has eight speakers and an eight channel amplifier. The radio displays MONSOON when the radio or the ignition is turned on. See your dealer/retailer for details.

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 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 appear on the 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.

Playing the Radio

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

(Volume): Turn 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. While the ignition is off, press to display the time. For RDS, press to change what appears on the display 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 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 you see the desired display, then hold the knob for two seconds. The radio produces a beep and the selected display is now the default.

AUTO (Automatic Volume): 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, AUTO VOL MEDIUM, or AUTO VOL HIGH displays. Each higher setting allows for more volume compensation at faster vehicle speeds. While driving, automatic volume increases the volume as necessary, to overcome noise at any speed. The volume level should always sound the same while driving. AUTO VOL 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 displays.

Finding a Station

BAND: Press to switch between FM1, FM2, AM, or XM1 or XM2. The display shows the selection.

ADJ (Adjust): Turn to select radio stations.

SEEK : Press to go to the next or to the previous station and stay there. To scan stations, press and hold either arrow for two 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. To scan preset stations, press and hold either arrow for more than four seconds until two beeps sound. The radio goes to the first preset station stored on the pushbuttons, plays for a few seconds, then goes to the next preset station. Press either arrow again to stop scanning presets. The radio only seeks and scans stations with a strong signal that are in the selected band.

Setting Preset Stations

Up to 30 stations (six FM1, six FM2, and six AM, six XM1 and six XM2), can be programmed on the six numbered pushbuttons. To program presets:

RDS Messages

ALERT!: Alert warns of local or national emergencies. When an alert announcement comes on the current radio station, ALERT! displays. The announcement is heard 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 appears every three seconds. To scroll through the message, press and release the MSG button. A new group of words display after every press of this button. Once the complete message has displayed, MSG disappears from the display 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 or the radio is turned to a different station. When a message is not available from a station, NO MESSAGE displays.

MSG or TRAF (Traffic): If TRAFFIC displays, the tuned station broadcasts traffic announcements. If the current tuned station does not broadcast traffic announcements, press and hold this button for two seconds and the radio seeks to a station that does. When a station that broadcasts traffic announcements is found, the radio stops seeking and TRAF in brackets displays. When a traffic announcement broadcasts on the tuned radio station, you will hear it. If no station is found that broadcasts traffic announcements, NO TRAFFIC INFO displays. If TRAF is on the display, press and hold the MSG or TRAF button for two seconds 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 for XM™ Only

See XM Radio Messages later in this section for further detail.

Playing a CD

Insert a CD partway into the slot, label side up. The player pulls it in and the CD should begin playing.

Press the eject button or the DISP knob to insert a CD while the ignition is off.

If the ignition or radio is turned off while a CD is 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.

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.

Care of 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.
