If the station does not broadcast traffic announcements,
press this button and the radio will seek to a station
that does. When a station that broadcasts traffic
announcements is found, the radio will stop seeking and
TRAF and brackets will appear on the display. If no
station is found that broadcasts traffic announcements,
NO TRAFFIC INFO will appear on the display.
If TRAF is on the display, press the TRAF button to turn
off the traffic announcements.
The radio will play the traffic announcement even
if the volume is low. The radio will interrupt the play
of a CD if the last tuned station broadcasts
traffic announcements.
This function does not apply to XM™ Satellite
Radio Service.
