An on-vehicle massage system for a passenger vehicle that utilizes an air compressor on the passenger vehicle as a source of dynamic force and the power supply on the passenger vehicle as an electric power source to inflate and deflate air bags mounted in seats of the passenger vehicle to provide massage action. A pressure detecting circuit detects the air pressure in an air cylinder of the air compressor, so that the on-vehicle massage system is actuated only when a detected pressure value is high enough for normal and safe operation of the passenger vehicle. The on-vehicle massage system is economical and safe for use to relieve passengers' stiff muscles caused by long distance journey on the vehicle.
