[Canada?] Sport and Comfort mode
It's more of a European feature when driving through the mountains. When you put your foot on the gas it finds the gear and you get around pretty zippy. If you've driven in mountainous terrains you'll know what it means. On the majority of North American roads, I don't find the feature makes little difference. Since you're already using an auto transmission you want the tranny to do the work for you. If you feel the urge to take control just shift the gears yourself.
It's a nice to have, psychologically it makes you feel better - come on admit it, I will! I feel the car instantly becomes more powerful and responsive when I press the CS button lol.
