2.3-16 Self Leveling System Bleeding

[16VAlex]

I just replaced a pair of shocks on this car. I toped the resevour with Hydrolic fluid but the car still sagging quite a bit even after I drove it, maybe 1.5" to 2.0" lower than it should has. I think the system need to be bled, but I have never done this before, and I can't find a procedure in my Mercedes shop manual. If some know of a way to bleed this system. I'd be sure appreciate the help. Thanks
