Vitaly Petrov says it is too soon to determine what he will be doing in 2013.
The Russian made his debut for Renault (now Lotus) in 2010, moving across to the back-of-the-grid Caterham team at the beginning of this season.
And his manager Oksana Kosachenko said recently she is in talks with three teams about 2013.
"Before autumn we have to be ready to take some decisions. I don’t want to be in the situation which we faced last year," she said.
Kosachenko said the priority is to keep Petrov, 27, at Caterham.
So when will they be in a position to know more?
"I think after August," Petrov is quoted by the Russian website f1news.ru.
"Right now, all the talk about (drivers) moving around is just starting.
"The main thing is that the (Caterham) team is happy with me, they’ve said it in the press and to me personally," he revealed.
Petrov said he is not feeling "nervous" about the future.
"Maybe in another situation I would be, but because I have good results and we work well together as a team, I see no reason for that."
