Driving-in rules

Hello guys, In 3 weeks I get my new XC70 D5 AT. According to my friend, I don’t need to pay attention to driving rules. Also, the engine doesn’t need an oil change after the first 5t km. It doesn’t seem to me this year. Every new machine needs a certain care at the beginning. Has the engine and transmission management programmed a “drive-in softwae” which releases the full power after a few t km?? Who can give me more information? Gruss köbi
