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.
