Entertainment Systems
CD units are designed to play commercially pressed 12 cm (4.75 in)
audio compact discs only. Due to technical incompatibility, certain
recordable and re-recordable compact discs may not function
correctly when used in Ford CD players. Irregular shaped CDs,
CDs with a scratch protection film attached, and CDs with
homemade paper (adhesive) labels should not be inserted into
the CD player. The label may peel and cause the CD to become
jammed. It is recommended that homemade CDs be identified
with permanent felt tip marker rather than adhesive labels. Ball
point pens may damage CDs. Please contact your dealer for
further information.
AUDIO SYSTEM WARRANTY AND SERVICE
Refer to the Warranty Guide for audio system warranty information. If
service is necessary, see your dealer or qualified technician.
