Playing a Compact Disc Insert a disc partway into the slot, label side up. The player will pull it in. The compact disc symbol will appear on the display. If the ignition and the radio are on, the disc will begin playing. CD will appear on the display next to the compact disc symbol.

Full-size compact discs and the smaller discs are loaded in the same manner. If you're driving on a very rough road or if it's very hot, the disc may not play and E (error) and a number may appear on the radio display. If the disc comes out, it could be that: D The disc is upside down. D It is dirty, scratched or wet. D The air is very humid. (If so, wait about an hour and try again.) If any error occurs repeatedly or if an error can't be corrected, please contact your dealer. If your radio displays an error number, write it down and provide it to your dealer when reporting the problem. 3-12
