Power Mode - Will allow the transmission to hold gears longer, and will down shift at much lower throttle positions.
Normal Mode - Is an automated sensing mode, if the car feels you are pushing the car, it will use Power mode.
Hold Mode - Will prevent you from pushing the car really hard, and will limit the revs to around 4,000 rpm. A very usefull mode when you desperatley need fuel :) Hold will also keep it in the selected gear unless you physically select a different gear.
