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.

Playing the Radio

(Power/Volume): Press this knob to turn the system on and off. Turn this knob clockwise or counterclockwise to increase or to decrease the volume.

DISP (Display): When the ignition is turned off, press this knob to display the time. For XM™ (if equipped), press the DISP button 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 button until the desired option displays, then hold this knob for two seconds. One beep sounds and the selected display becomes the default.

AUTO VOL (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. 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 AVOL OFF (automatic volume off) displays.

To scan preset stations, press and hold either arrow for more than four seconds. PSCN displays and the two beeps sound. The radio goes to a preset station, plays for a few seconds, then goes to the next preset station. Press either arrow again or one of the pushbuttons to stop scanning presets. The radio only seeks and scans stations with a strong signal that are in the selected band.

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. To insert a CD with the ignition off, first press the eject button or the DISP (display) 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, READING and the CD symbol displays. As each new track starts to play, the track number also 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 will not play properly. If the surface of the CD is soiled, see Care of Your CDs and DVDs 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.

1 (Previous): Press this pushbutton to reverse within the track.

2 (Next): Press this pushbutton to fast forward within the track.

3 (Repeat): Press this pushbutton to hear a track over again. RPT ON displays. The current track continues to repeat. Press this pushbutton again to turn off repeat play. RPT OFF displays.

4 (Random): Press this pushbutton to hear the tracks in random, rather than sequential, order. RDM ON displays. Press this pushbutton again to turn off random play. RDM OFF displays.

SEEK : Press the left arrow to go to the start of the current or the previous track. Press the right arrow to go to the start of the next track. If a track is approximately 10 seconds into its song, press either the left or right arrow twice to get to the previous or next track. To scan tracks, press either arrow for more than two seconds until one beep sounds and SCAN displays. The CD searches the previous or next tracks at two seconds per track. Press either arrow to stop scanning.

DISP (Display): Press this button to see how long the current track has been playing. The elapsed time of the track appears on the display. To change the default on the display, track or elapsed time, press this button until the desired option displays, then hold the button for two seconds. One beep sounds and the selected display becomes the default.

BAND: Press this button to listen to the radio when a CD is playing. The inactive CD remains inside the radio for future listening.

(CD): Press this button to play a CD when listening to the radio. The CD symbol displays when a CD is loaded.

AUTO EQ (Automatic Equalization): Press AUTO EQ to select an equalization setting while playing a CD. The equalization is set whenever a CD is played. See "AUTO EQ" listed previously for more information. If you select an EQ setting for your CD, it is activated each time a CD plays.

(Eject): Press this button to eject a CD. Eject can be activated with either the ignition or radio off. CDs can be loaded with the ignition and radio off if this button is pressed first.

Playing an MP3 CD-R Disc

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

CD Messages

CHECK CD: If this message displays and/or the CD ejects, 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 may 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. If the radio displays an error message, write it down and provide it to your dealer when reporting the problem.
