Pontiac 2004 Grand Am - Manual (Page 155)

TRAF (Traffic): If TRAF appears on the display, the
tuned station broadcasts traffic announcements.
To receive the traffic announcement from the tuned
station, press this button. Brackets will be displayed
around TRAF and when a traffic announcement comes
on the tuned radio station you will hear it.
If the current tuned station does not broadcast traffic
announcements, press the TRAF button and the
radio will seek to a station that does. When the radio
finds a station that broadcasts traffic announcements,
the radio will stop and brackets will be displayed around
TRAF. When a traffic announcement comes on the
tuned radio station you will hear it. If no station is found,
NO TRAFFIC will appear on the display.
If the brackets are on the display and TRAF is not, you
can then 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, NO TRAFFIC will appear on the
display.
Your radio will play the traffic announcement if the
volume is low. Your 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.
