Theft-Deterrent Feature 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. If the radio is removed from your vehicle, the original VIN in the radio can be used to trace the radio back to your vehicle. With THEFTLOCK® activated, the radio will not operate if stolen. Some audio controls can be adjusted at the steering wheel. They include the following: See "OnStar® Steering Wheel Controls" under OnStar® System on page 2-37 or OnStar® System on page 4-47 for more information.
