    Abstract: A vehicular hydraulic jack system is provided including a fluid reservoir mounted within the vehicle and a fluid pump connected to the fluid reservoir. The fluid pump is adapted to generate pressurized fluid upon the actuation thereof and further release pressurized fluid when deactuated. Four hydraulic jacks each include a cylinder adapted to extend downwardly upon receipt of pressurized fluid and further retract when the pressurized fluid is released therefrom. Also included is a transmission control mechanism including a sensor for generating a park signal only when a transmission of the vehicle is placed in a park mode. A hydraulic jack control panel functions to direct and release pressurized fluid to and from the hydraulic jacks via the fluid pump only upon the receipt of the park signal.
