Playing a Compact Disc in the Single Remote Disc Player (If Equipped) A disc that has been ejected but is still sitting in the remote CD player will be pulled back into the player after approximately 30 seconds. Thisprotects the disc and player from damage. The disc will not start playing. To remove the disc, press the EJECT button and remove the disc from the player. All of the compact disc functions are controlled by the radio buttons except for EJECT. When a disc is in the player, a CD symbol will appear on the display. When a disc is playing, the letters CD will appear next to the CD symbol in the bottom left corner. The track number will also be displayed. If the disc comes back out and ERR appears on the display, it could be that: The disc is upside down. It is dirty, scratched or wet. There's too much moisture in the air. (Wait about an hour and try again.) You are driving on a very rough road. Please contact your dealership if any error recurs or cannot be corrected. If you have this option, you can play one compact disc (CD) at a time. To load a CDinto the player, hold the disc with the label side up and insert it carefully into the player (approximately halfway). The disc will automatically be pulled into the player. If the radio is off and the ignition is on when a CD is inserted, the radio will turn on and begin playing the CD. It is possible to load and unload CDs with the ignition off. To load a disc with the ignition off, press the EJECT button on the remote player and then insert the disc. To remove the disc, press the EJECT button and remove the disc from the player. 3-24
