If the ignition or radio is turned off with a CD in the player, it stays in the player. While a CD is in the player and the ignition is turned on, the radio must be turned on before the current CD starts playback. When the ignition and radio are 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.

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.

    • 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.

Using the Auxiliary Input Jack

AUX IN (Auxiliary Input): The radio system has an auxiliary input jack located on the lower right side of the faceplate. This is not an audio output. Do not plug the headphone set into the front auxiliary input jack. An external audio device such as an iPod, laptop computer, MP3 player, CD changer, or XM™ receiver, etc. can be connected to the auxiliary input jack for use as another source for audio listening. The auxiliary input jack also accepts cell phone connectors. Plug the cell phone connector into the auxiliary input jack to hear a person speck on a cell phone during a conversation through the vehicle sound system. Drivers are encouraged to set up any auxiliary device while the vehicle is in PARK (P). See Defensive Driving for more information on driver distraction. To use a portable audio player, connect a 3.5 mm (1/8 inch) cable to the radio's front auxiliary input jack. While a device is connected, turn the portable audio player on and press the radio CD/AUX button to hear audio from the device over the vehicle speakers.

(Power/Volume): Turn this knob clockwise or counterclockwise to increase or decrease the volume of the portable player. Additional adjustments on a portable device might be needed to get the desired volume.

CD/AUX (CD/Auxiliary): Press this button once to play a CD while a portable audio device is playing. Press this button a second time for the system to begin playing audio from the connected portable audio player. Once in this mode, Auxinput displays. If the auxiliary jack does not detect the presence of an output jack, the auxiliary mode does not display.
