the beauty of the system is, lets say you are running at 80kph at 5th or 6th gear/speed and you have to slow down by braking and by doing so your speed goes down to 30kph. you will see in the indicator that the gears/speed are automatically downshifting (-) for you, at 30 kph it may well be at around the 3rd gear/speed.
-- is this in manual mode? wherein the gears downshift automatically given the change in speed?

full auto mode (you just have to pick the right drive setting (d1,d2 etc)
-- what other modes do CVTs have? D1,D2,etc..
