Buick 2005 Rendezvous - Manual (Page 220)

TRAF (Traffic): If TRAF appears on the display, the
tuned station broadcasts traffic announcements.
Press this button to receive the traffic announcement
from the station and brackets will be displayed around
TRAF. When a traffic announcement comes on the
tuned radio station you will hear it.
If the station does not broadcast traffic announcements,
press the TRAF 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 brackets will be displayed around TRAF. If no
station is found that broadcasts traffic announcements,
NO TRAFFIC will appear on the display.
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 broadcasts traffic announcements. If no
station is found that broadcasts traffic announcements,
NO TRAFFIC will appear on the display.
The radio will play the traffic announcements if the
volume is low. The radio will interrupt 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.
