Radio Messages CAL (CALIBRATE): Your audio system has been calibrated for your vehicle from the factory. If CAL appears on the display it means that your radio has not been configured properly for your vehicle and must be returned to the dealer for service. Do not add paper labels to CDs, they could get caught in the CD player. Do not play 3 inch CDs without a standard adapter CD. If an error appears on the display, see "CD Messages" later in this section. 1s(Reverse): Press and hold this pushbutton to reverse quickly within a track. You will hear sound at a reduced level.

DISP (Display): Press this button to see which track is playing. Press it again within five seconds to see how long it has been playing.

The selected display will now be the default. Playing a CD Insert a CD partway into the slot, label side up. The player will pull it in. The CD should begin playing. If you want to insert a CD while the ignition or the radio is off, first press the eject or DISP button. If you turn off the ignition or radio with a CD in the player, it will stay in the player. When you turn on the ignition or system, the CD will start playing where it stopped, if it was the last selected audio source. As each new track starts to play, the track number will appear on the display. The CD player can play the smaller 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. You may experience an increase in skipping, difficulty in finding tracks, and/or difficulty in loading and ejecting. If these problems occur try a known good CD. 3-51
