Radio Messages - Chevrolet 2003 Avalanche Owner's Manual

When a message is not available from a station,
NO INFO will be displayed.
TRAF (Traffic): If TRAF appears on the display, the
tuned station broadcasts traffic announcements
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 this button and the radio
will seek to a station that does. When the radio finds a
station that broadcasts traffic announcements, it will
stop and TRAF will be displayed. 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 TRAF is on the display you can press the TRAF
button to turn off the traffic announcements.
Your radio will play the traffic announcement even if the
volume is muted or interrupt the play of a CD if the
last tuned station broadcasts traffic announcements.
This function does not apply to XM™ Satellite Radio
Service.
