[MN2///M]

Sounds like you are pushing the stalk down fully, for lane changes, just a slight depress is all that is needed. The indicator will flash 3 or 5 times depending on settings.

For full turns, fully depress and the indicator will stay on until until you execute the turn. Off the top of my head, I think you have to turn the wheel 30 to 40 degrees in the direction you are turning before the indicator will turn off.
