A method is provided for initiating a parking maneuver for parallel parking a vehicle between a first object and a second object. A target parking space is measured. A determination is made whether the measured target parking space is sufficient to allow an autonomous parallel parking maneuver. A region of feasible starting locations is determined to successfully perform the parallel parking maneuver between the first object and the second object if the available parking space is sufficient. A position of a midpoint of a rear axle is determined in relation to the designated region. A determination is made whether the midpoint of the rear axle is within the designated region. A driver of the vehicle is signaled in response to an instantaneous location of the midpoint of the rear axle vehicle being a feasible starting location to initiate the parallel parking maneuver.
