A method and apparatus for automatically leveling a vehicle is provided, employing air springs, a sensor and a controller. The air springs are each mounted to the vehicle, and each can be at least partially inflated to provide suspension for the vehicle. Each of the air springs can also level the vehicle when the vehicle is parked. The sensor is mounted to the vehicle to sense pitch and roll of the vehicle relative to a reference level plane. The sensor also produces an orientation signal representing the vehicle pitch and roll. In response to the signal, the controller may cause at least one of the air springs to either inflate to move the vehicle upwardly, or deflate to move the vehicle downwardly relative to a ground surface, until the orientation of the vehicle reaches the reference level plane within a tolerance.
