Radio Messages
CAL (Calibration): 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 dealership for service.
Playing a Compact Disc
Insert a disc partway into the slot, label side up.
The player will pull it in. The disc should begin playing.
The display will show CD. If you want to insert a
compact disc with the ignition off, first press RCL or
the eject button.
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.
Do not add paper labels to discs, they could get caught
in the CD player.
