Winter drive - you must be going under 7 mph when you engage it. It keeps the SUV in 3rd gear (max ~ 40 mph) so that speed is reduced, control is better. Useful for when roads are slick with snow/ice, especially curvy, hilly roads. Power drive - gives slightly more power when accelerating. Increases the RPM's for each gear. Mileage will suffer, though.
