I pulled this off the net- Maybe this will help you?
Like any all-wheel drive model, 4MATIC-equipped Mercedes-Benz vehicles engage all four wheels to provide optimal traction. In normal conditions, 4MATIC uses a center differential to provide superior handling and balance, providing unparalleled confidence behind the wheel. But 4MATIC utilizes a 4-wheel Electronic Traction System to take things a step further, by optimizing torque to each wheel based on conditions, your vehicle will have the best traction possible at all times.
For example, when one tire experiences wheel slip due to an ice patch or snow bank, the 4MATIC all-wheel drive system distributes more torque to the other three wheels to help grip and performance. This is especially useful on occasions where you find yourself stuck in the snow or on an icy portion of a driveway or parking lot.
Another benefit of 4MATIC is that its fully integrated with the drivetrain and the numerous active safety and driver assistance aids. That helps you, as the driver, to be aware of where wheel slip is occurring and when traction is low so you can alter your drive accordingly.

thx. looking for a little more depth. i owned a few of the early 4matics. the system was not full time. from a standing start, the front differential would engage as soon as you start moving and then, if added traction is not needed, drop off at about 25 or so mph. if traction was needed while driving, the differential would engage on the fly.
so question is do the current 4matics operate the same way, or, are they now full time?
thx, ron
ps: hence the term "4matic"

I believe the system is full time; in the sedans the system bias’s the power delivery to the rear wheels, but I don’t know if the SUV’s follow suit.
