I have 3 questions about the locking differentials in my 2016 G550.
Question 1. Is it harmful to have center and rear locking differentials engaged when driving at 20MPH on a straight road?
Question 2. My car made a sudden clanking sound, and I felt the jolt, too after I disengaged the center and rear locking differentials while the car is in motion at 20 MPH. I am wondering why this happened? How harmful is it to the car?
Question 3. What is the correct way to engage and disengage the locking differentials? Should I have them engaged or disengaged while the car is at rest?
Thank you!

Out Of Control!!
Not to sound short, however I am sure that if you returned to the selling dealer the salesperson will be happy to go over the delivery process with you and answer any other questions.
To prepare myself I would also study the manual prior to the dealer visit!!

Ahh great question!!!
After 2008 - you should NOT be able to engage locking differentials unless in Low Range. However, there was talk of having this changed in the 2016 Model. Sounds like they did it.
That said, read the manual. You were going fast to disengage the locks, Manual says it can be engaged and disengaged at a stand still however it might take some movement to fully unlock or engage.
For the Low range case the truck need to be in Neutral and rolling (No faster than 5mph) to engage.
I would advise researching and understand when and what terrains you need and should lock your differentials. Also you should lock them at least once a year to make sure they don't have any issues. When they sit unused like in 90% of the ones in the US they get stuck and wont lock.
You should take it offroad and lock all your differentials and unlock them. You will know if you have a problem, but in the end it is under warranty so who cares if it broke
