A driver assist system for a vehicle includes at least one non-visual sensor and a forward-viewing camera disposed that is part of a multi-camera vision system of the vehicle that includes at least two side cameras and a rear backup camera. A video display screen is viewable by a driver of the vehicle when the driver is normally operating the vehicle. During a driving or parking maneuver of the vehicle, images derived, at least in part, from image data captured by at least some of the cameras are displayed by the video display screen, and at least one indication is provided to the driver of the vehicle during the driving maneuver. A unitary image is synthesized from image data captured by the multi-camera vision system and approximates a view as would be seen by a virtual camera at a single location exterior of the vehicle.
