yeah i googled just
"What does the MANU button near the gear lever do
MANU = Manual shift mode. When you are in manual mode, and you put the shifter in L, the tranny will stay in 1st gear, when you put the shifter in 2nd, the tranny will shift to 2nd gear (where when you are not in Manual mode, the car will still start from 1st... or remain in 1st depending on your speed), and when you put the shifter in D, the tranny will shift to 3rd. (but note that when the car is at complete stop, and the shifter is in D, and in manual mode, the car will still start from 2nd gear). Basically, if you use the manual mode, and shift manually, the car will shift a lot faster.... and thus the car will go a lot faster.
