A vehicular display system includes an electronic control unit (ECU), a plurality of cameras including a driver-side rear corner camera and a passenger-side rear corner camera disposed at respective driver-side and passenger-side rear corner regions of the vehicle. The ECU includes an image processor operable to process image data captured by any of the plurality of cameras and generate video images. A video mirror display screen is disposed at an interior rearview mirror assembly of the vehicle and is operable to display video images provided by the ECU. Responsive to a triggering event, the ECU, via processing of image data captured by at least one of the driver-side and passenger-side rear corner cameras, generates cross-traffic view video images and provides the cross-traffic view video images to the video mirror display screen. The cross-traffic view video images are displayed in a split-screen format at the video mirror display screen.
