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 station does not broadcast traffic announcements, press this 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 supports traffic announcements. If no station is found, NO TRAFFIC will appear on the display. The radio will play the traffic announcements even if the volume is low. The radio will interrupt the play of a cassette tape or CD if the last tuned station broadcasts traffic announcements. This function does not apply to XM™ Satellite Radio Service. Radio Messages CAL (Calibrate): The audio system has been calibrated for your vehicle from the factory. If CAL appears on the display, it means that the radio has not been configured properly for the vehicle and must be returned to your GM dealer for service. LOCKED: This message is displayed when the THEFTLOCK® system has locked up. Return your vehicle to your GM dealer for service. If any error occurs repeatedly or if an error cannot be corrected, contact your GM dealer. 3-93
