If any error occurs repeatedly or if an error cannot be corrected, contact your dealer/retailer.

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. You can however, connect an external audio device such as an iPod™, laptop computer, MP3 player, CD changer, or cassette tape player, etc. 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 P (Park). See Defensive Driving on page 4-2 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.
