A vehicle machine with a belt system and a belt. The belt system includes a tensioner with a tensioner moving member which is movably supported on a tensioner stationary member; a tensioner pulley which is rotatably supported on the tensioner moving member and around which at least a portion of the belt is engaged. The belt system includes a bias member, the bias member biasing the tensioner moving member with the tensioner pulley pressing the belt. The belt system includes a controllable electrical current supply and an electromagnetic brake lock, the electromagnetic brake lock including a brake lock electromagnetic coil and a brake lock magnetic target, the electromagnetic brake lock disposed between the tensioner moving member and the tensioner stationary member wherein a controlled current supplied from the controllable electrical current supply to the brake lock electromagnetic coil inhibits the tensioner moving member from moving relative to the tensioner stationary member.
