For 1990-2009 cars

Federal law requires General Motors to label major parts of the vehicle with a theft deterrent label. The theft deterrent label (4) is permanently affixed to the interior surface of the right and left front and rear doors and contains the complete vehicle identification number (VIN).

Important: Theft deterrent labels (4) are not to be defaced, removed or covered over. These labels must be shielded from paint, rustproofing, and undercoating (dealer preparation included).

For further information on theft deterrent labels, refer to Anti-Theft Labeling .
