Thank you for the quick advice. I've also called local Mecedes dealer and this is what they said:

Keep the car in the garage over night and start the car next morning and let it idle for 2-3 minutes. Check the ATF level and it should be 10 mm below the lower mark on th dipstick.

Pretty specific, isn't it? Any comments?

Again, thank you and many others who have responded to my other postings. This Forum is truely awesome!
