If the brackets are on the display and TRAF is not,
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 that broadcasts traffic
announcements, NO TRAFFIC displays.
The radio plays the traffic announcement if the
volume is low. The radio interrupts 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 CD
Insert a CD partway into the slot, label side up.
The player pulls it in and READING DISC and the
CD symbol appears on the display. If you want
to insert a CD with the ignition off, first press the
EJECT button or push the RCL knob.
If the ignition or radio is turned off with a CD in the
player it stays in the player. When the ignition or
radio is turned on, the CD starts to play where it
stopped, if it was the last selected audio source.
When the CD is inserted, the CD symbol appears
on the display. As each new track starts to
play, the track number appears on the display.
The CD player can play the smaller 3 inch (8 cm)
single CDs with an adapter ring. Full-size CDs and
the smaller CDs are loaded in the same manner.
