A plus-two belt system is provided. The plus-two belt system is a supplement to a traditional three-point belt system. The plus-two belt system has a longitudinal webbing anchored at a first end and coiled on a retractor at a second end. When an occupant is sensed and the vehicle engine is on, a reminder chime can sound when a magnetic strip in the webbing of the plus-two belt system is detected. The magnetic strip can be detected with a Hall effect sensor and the Hall effect sensor can be located adjacent the retractor.
