A vehicular automated parking system includes a camera having a field of view rearward of the vehicle. When the vehicle is parked in a parking space, with a forward vehicle parked in front of the vehicle and a rearward vehicle parked behind the vehicle, the vehicular automated parking system determines a forward limit of the parking space responsive to a driver of the vehicle driving the vehicle forward until a front end of the vehicle is close to the forward vehicle. Responsive to the determined forward limit of the parking space, and responsive to processing by an image processor of image data captured by the camera, the vehicular automated parking system controls the vehicle when the vehicle is leaving the parking space in a manner that avoids the forward vehicle parked in front of the vehicle and the rearward vehicle parked behind the vehicle.
