Trunk-Mounted CD Changer If your vehicle has the CD changer, you can play up to 12 CDs continuously. Normal size CDs may be played using the trays supplied in the magazine. The small 3 inch (8 cm) CDs can be played only with specially designed trays. Notice: Placing heavy objects, which may shift or slide while driving, in the trunk could damage the CD changer. If your vehicle has the optional CD changer, do not put heavy objects in the trunk. You must first load the magazine with CDs before you can play a CD. Each of the 12 trays holds one CD. Slide the button on the top of the magazine and gently pull out one of the trays. Load the trays from top to bottom, placing a CD on the tray label side up. If you load a CD with the label side down, the CD will not play and an error will occur. Gently push the tray back into the magazine slot until it locks into place. Repeat this procedure for loading up to 12 CDs in the magazine. 3-77
