(4) If in proceedings for an offence under subsection (1) it is proved that the defendant had possession of the motor vehicle and that, during the time it was in the possession of the defendant, or shortly after the time it ceased to be in the possession of the defendant, the odometer reading was less than the odometer reading at the time the defendant acquired possession of the vehicle, it shall be presumed, in the absence of proof to the contrary, that the defendant interfered with the odometer of the vehicle.
