Radio Messages CAL (Calibration): The audio system has been calibrated for your vehicle from the factory. If CAL appears on the display it means that the radio has not been configured properly for your vehicle and must be returned to the dealer for service. LOC (Locked): This message is displayed when the THEFTLOCK® system has locked up. Take the vehicle to the dealer for service. If any error occurs repeatedly or cannot be corrected, contact your dealer. If the ignition or radio is turned off, with a CD in the player, it stays in the player. When the ignition or radio is turned on, the CD starts playing where it stopped, if it was the last selected audio source. As each new track starts to play, the track number appears on the display. 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 may 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 may 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 will not play properly. If the surface of the CD is soiled, see Care of Your CDs on page 226 for more information. Playing a CD Insert a CD partway into the slot, label side up. The player pulls it in and the CD should begin playing. CD appears on the display. If you want to insert a CD with the ignition off, first press the eject button or the RCL knob. If you insert a CD with the radio off and the ignition on, it starts to play. 195
