Well, my wife finally got to try out the traction system on her 98-ML320. Unfortunately I had to retrieve her in my 1952 GMC.

The little truck was crossing a ditch at an angle, which left one front wheel and one rear wheel very light. The traction control system activated, and we could hear it cycling but the fron wheel just continued to spin. A gentle rock backwards and then forward got her moving again, but, we thought that that was what the traction control system was supposed to do. (My 52Jimmy only suffers 12 degrees of front wheel slip before the automatic transfer locks in, so much for new technology!)

Question is, how much wheel spin does the system allow? Does it require extensive wheel spin before the brakes apply and divert the torque? The system never gave a malfunction indication. Need some information on if it is working or if the dealer can make changes to the settings.
