Anyone know what this means?

On the MB Approved used site, each car has a list of equipment. Three things are listed fairly regularly: Technical modifications (09), MBUK Lock - Remove to allow 0-R75 and PRE-SAFE
Any ideas what these three things are?

PRE-SAFE is an anticipatory crash preparation system, which pre-tensions the seatbelts and and can close the sunroof, stiffen the seat bolsters, etc depending on the car, situation, etc. More details and demonstration video here:

Mercedes-Benz PRE-SAFE® Brake | Euro NCAP - For safer cars crash test safety rating

Not sure about the other two, but guessing the MBUK lock may have something to do with locking wheel nuts? The modifications one is probably just about the changes made for that model year for the model in question.

Thanks Moca.
