I do the same thing. But I know people who don't and Dealer said you don't have to because compressor does not turn on right away anyway is this true? If it is then you will save wear and tear on your c/c buttons since there's no switch to turn off automatically. Will it retain moisture in the duct or pan if you don't turn it off?

This probably answers my question(s):

If you have the windows up, then it will most likely occur all the time when the A/C is in OFF position - just from breathing and other evaporations in the vehicle. I believe late model MB vehicles (and other manufacturers) design new cars to turn on the compressor for a short while as your key engages the "ON" position. The reason for this is to have the A/C operate for a short period so that the condensation doesn't occur. Now, if you turn your A/C off, you'll have condensation. Notice that the manual says that the A/C system in AUTO mode is always ready. So just leave it in AUTO mode and set your desired temps.
The second reason the system should be on is to avoid fungi growth in the system. Depending on your ambient conditions, "things" (living organisms) may grow in there and cause a bad stench. Leaving it OFF is a catalyst for such growth. Leave it in AUTO and you'll have no problems.
