    a front-mounted video camera at a front portion of the equipped vehicle;

    said front-mounted video camera having at least a forward field of view external of the equipped vehicle;

    said front-mounted video camera operable to capture video image data at least forward of the equipped vehicle during the maneuver of the equipped vehicle;

    a first side-mounted video camera at a driver-side side portion of the equipped vehicle;

    said first side-mounted video camera having at least a sideward field of view external of the equipped vehicle;

    said first side-mounted video camera operable to capture video image data at least sideward of the equipped vehicle during the maneuver of the equipped vehicle;

    a second side-mounted video camera at a passenger-side side portion of the equipped vehicle;

    said second side-mounted video camera having at least a sideward field of view external of the equipped vehicle;
