If the current tuned station does not broadcast traffic announcements, press and hold this button for two seconds 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. When a traffic announcement comes on the tuned radio station you will hear it. If no station is found that broadcasts traffic announcements, NO TRAFFIC INFO will appear on the display. If TRAF is on the display, press and hold the MSG button for two seconds 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.
