I think that bit in the manual about the vacuum line is a holdover from the older V6 cars that had the vacuum hose connected to manifold vacuum. On the Milano they switched to port vacuum, so there is no vacuum on that line with the throttle at idle (you should see vacuum on the line as soon as you open the throttle plate.)

So on my old Milano 2.5, at least, there was no need to disconnect or pinch the line or anything to set static timing at idle.
