How long to lower airmatic suspention

I am the proud owner of a 2012 GHL 450, while checking out all of the gadgets it I was wondering how long should it take to lower it through the Airmatic?

Thanks, doesn't seem to be lowering. I guess that's better than lowering and not coming back up though.

guess your right, on the ML63 there is a button to lower and raise it... lowering doesn't go to far, raising will bring it up a good 6-8 inches ? for going offroad i assume.... i use it to lower the hitch when my boat wheel sunk....

It raises and lowers maybe 2" to 3" - or right about there. Without timing it, I'd say it takes about 30 seconds for it to fully lower. Watch in the rearview mirror as it does it - that's an easy way to see what's going on - focus on something in the mirror and take note of where it is in the mirror. It seems the front and rear lower at different times so you'll see that manifest in the mirror. You could also compare the distance from ground to the center of each wheel well when lowered/raised.
