2009 Chevrolet Silverado 2500 HD Extended Cab Owner's Manual - Page 38

Shoulder Belt Height Adjuster The vehicle has a shoulder belt height adjuster for the driver and right front passenger. Adjust the height so that the shoulder portion of the belt is centered on the shoulder. The belt should be away from the face and neck, but not falling off the shoulder. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash. To move the adjuster down for the regular and crew cabs, squeeze the buttons (A) on the sides of the height adjuster and move the height adjuster to the desired position. To unlatch the belt, push the button on the buckle. The belt should return to its stowed position. Before a door is closed, be sure the safety belt is out of the way. If a door is slammed against a safety belt, damage can occur to both the safety belt and the vehicle. Regular and Crew Cab 1-32
