The German shocked the world of F1 at the end of the 2016 season when he announced his retirement just a few days after winning the drivers' title for the first time in his career.
The former Mercedes and Williams star suggested at the time that he could return to drive again in the future but was eager to focus on his family life for the time being.
The 31-year-old has now said he has no intention to drive again competitively but is likely to remain involved in F1, not ruling out a role either in team management or assisting the current drivers.
Rosberg told Sport Bild: "I'm looking for new ways and I'm positively relaxed about it. One thing is for sure: I want to stick with racing in some capacity, whatever it may be.
"But I won't be coming back as a driver, no way. I'm thankful even though I put my life upside down by retiring from the sport.
"But I followed my heart and I'm totally happy to close my personal F1 book with winning the world title.
"I achieved everything I set out to achieve. Now, my new life will be as big a challenge [as F1 was].
"I want to be as successful. But now I can decide on my own what I want to do and I'm not being driven as much."
