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.

Additional volume adjustments might be needed from the portable device if the volume does not go loud or soft enough.

CD/AUX (CD/Auxiliary): Press this button to play a CD when a portable audio device is playing. Press this button again and the system begins playing audio from the connected portable audio player. If a portable audio player is not connected, No Input Device Found displays. Using the Auxiliary Input Jack 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. However, an external audio device such as an iPod, laptop computer, MP3 player, CD player, or cassette tape player, etc. can be connected to the auxiliary input jack for use as another source for audio listening. Drivers are encouraged to set up any auxiliary device while the vehicle is in PARK (P). See Defensive Driving on page 356 for more information on driver distraction. 304
