"I'm trusting in the fact that I usually adapt well to new circuits," the seven-times world champion said.
"I haven't seen much of it (the new Istanbul circuit) but I know that it's quite hilly and apparently has long fast turns. And that sounds good for a start," he told his website.
The 36-year-old has seen a string of circuits come and go since he made his debut with the Jordan team in 1991, including the latest additions of Malaysia, Bahrain and China.
"The race in Istanbul is going to be a premiere that will surely be very interesting for all of us," he said.
Champions Ferrari have had a troubled season after dominating 2004, when Schumacher won 13 of the 18 races.
This year, the German has won just once -- the six-car U.S. Grand Prix fiasco at Indianapolis in June that could barely be called a race.
However he finished a strong second at the last Hungarian Grand Prix on July 31.
"You're really eager to start driving again after a break," said Schumacher. "Many of the others may have needed this short break but if it had been up to me, I could have done without it. I'm happy to continue now."
The German said he had spent time with friends on a motorcycle tour of Norway and in the south of France to celebrate the birthday of Michelle Yeoh, the Malaysian fiancee of team boss Jean Todt.
