If the brackets are on the display and TRAF is not, you
can then press the TRAF button to remove the
brackets or use the TUNE knob or the SEEK arrows to
go to a station that supports traffic announcements.
If no station is found, NO TRAFFIC will appear on the
display.
Your radio will also interrupt the play of a CD if the last
tuned station broadcasts traffic announcements and
the brackets are displayed.
This function does not apply to XM™ Satellite Radio
Service.
Playing a Compact Disc
The integral CD player can play the smaller 8 cm single
discs with an adapter ring. Full-size compact discs
and the smaller discs 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.
3-76
Do not add paper labels to discs, they could get caught
in the CD player.
Do not play 3 inch discs without a standard adapter disc.
If an error appears on the display, see "Compact Disc
Messages" later in this section.
