Just push the Info button - that cycles you through different screen display options in all modes (Live View, VF shooting, and Image Playback). You can get the electronic level on the main LCD in both Live View and VF shooting, as well as in the VF (using the AF points). I find it especially useful when shooting with lenses that have older tripod collars (the newer ones have detents at 90° increments, which is very useful).
