go to sports mode or any of the "creative zone" settings like av, tv, m or p and just press the button to the right of the top lcd screen that has the picture of a timer and four squares next to it until you see those 4 squares appear on the upper LCD screen
I really don't mean to sound like an ass, but have you tried reading the manual? Digital SLRs are generally very complex pieces of equipment, and it you really cannot expect them to be completely intuitive and self-explanatory. Of all the manuals I've owned for digital equipment, both hardware and software, none have seen as much use as the one for my DSLR. Not just to look up how to do this or that, but also to get acquainted with features I might otherwise have overlooked.
Also, don't use the pre-defined modes (Auto, Sports, Macro, etc). It does take a bit of practice, but if you teach yourself how to use the Program, Aperture priority, Shutter priority and even Manual, you will have much more control over the look of the images. This will, ultimately, lead to better images and fewer missed opportunities.
