Those systems are reacting to instability in the steering and braking system - apparently due to weight shift on the axles simulating impending slipping, which is a real possibility due to the height and wind loading surface of the Solera. Got a feeling MB has throughly researched the action of these systems, but you might check with a dealer and see if there is a firmware upgrade. For me, if those lights start blinking, telling me the systems are reacting to conditions, I'll just pull over and wait out the storm!!
