I locked my center diff on N because the car was stopped and I'm parking on a steep driveway but it wasn't engaging, so while i have the brake pressed, i put it in R, from N and it engaged. Then i parked the car.
The car felt off when i pulled out of the driveway and realized about 20ft of driving, i forgot the cdiff was still locked so i put it in N then unlocked the cdiff, which it disengaged instantly, and drove away and it was back to normal.
I'm not sure if i did it correctly but it all worked out. This all happened on a paved surface.
