• There may have been a problem while burning the CD. • The label may be caught in the CD player. If the CD is not playing correctly, for any other reason, try a known good CD.

If the radio displays an error message, write it down and provide it to your GM dealer when reporting the problem. Theft-Deterrent Feature (RDS Radios) THEFTLOCK® is designed to discourage theft of your vehicle's radio. The feature works automatically by learning a portion of the Vehicle Identification Number (VIN). If the radio is moved to a different vehicle, it will not operate and LOCKED will appear on the display. When the radio and vehicle are turned off, the blinking red light indicates that THEFTLOCK® is armed. With THEFTLOCK® activated, the radio will not operate if stolen. Theft-Deterrent Feature (Non-RDS Radios) THEFTLOCK® is designed to discourage theft of your vehicle's radio. The feature works automatically by learning a portion of the Vehicle Identification Number (VIN). If the radio is moved to a different vehicle, it will not operate and LOC will appear on the display. With THEFTLOCK® activated, the radio will not operate if stolen. Radio Reception AM The range for most AM stations is greater than for FM, especially at night. The longer range, however, can cause stations to interfere with each other. AM can pick up noise from things like storms and power lines. Try reducing the treble to reduce this noise. FM FM stereo will give you the best sound, but FM signals will reach only about 10 to 40 miles (16 to 65 km). Tall buildings or hills can interfere with FM signals, causing the sound to come and go. 3-72
