Max Mosley will decide in June whether to commit to the FIA presidency for another four-year term.
The 68-year-old Briton, earlier this year embroiled in a sex scandal but now hailed by some as the champion of a new sustainable formula one, said at the Motor Sport Business Forum in Monaco: "I don't think I shall stand again, but we shall see."
His current term runs out late in 2009.
Mosley had earlier ruled out remaining president into his 70s, but in the immediate aftermath of the sex scandal this year he admitted "pressure" to stay on.
"I am delaying a decision until June," he said on Wednesday.
