To set this feature, gently pull on the belt, or lean forward and then sit back. The belt will retract and rest lightly against the occupant. When the safety belt is unbuckled or when the vehicle is turned off, the tension reducer will deactivate. The belt should go back out of the way. 1-22 To unlatch the belt, just push the button on the buckle. Before you close a door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle.
