Step 3 = The second character cites the manufacturer. The letter G is assigned to a General Motors vehicle.
Step 4 = Learn the division from the third character. Number 1 is for Chevrolet. Other GM codes are 2 for Pontiac, 3 for Oldsmobile, 4 for Buick, 6 for Cadillac, and 8 for Saturn.
Step 5 = Gross Vehicle Weight Rating, or GVWR, is revealed by the fourth character.
