Daniil Kvyat says he has no idea when he can expect a decision, or even talks, with Red Bull and Toro Rosso regarding his future.
The Russian driver is into the final leg of a wretched 2016 season in which he was demoted to Toro Rosso, scoring just two points since then.
His demotion was followed by reports that he was to be dropped by the Red Bull family at the end of 2016.
However, in recent weeks Red Bull advisor Helmut Marko has insisted that Kvyat just needs time to refind his form, which is a sentiment echoed by Toro Rosso team boss Franz Tost.
For now Kvyat admits his future remains uncertain.
Asked when he expects a decision on 2017, the 22-year-old told Sky Sports: "I don't expect anything."
He added: "I just do my job.
"When the moment will come, we will talk. It hasn't come yet and whenever it comes I'm pretty sure it will happen.
"It's a little bit between me and Red Bull. I've always been loyal to them and now I'm giving my best for Toro Rosso."
Kvyat's chances of retaining his seat have not been helped by Toro Rosso's recent struggles.
A lack of pace in recent races, partially due to running a year-old Ferrari engine, has seen the team return to basics in the hope of regaining their lost form.
"I just keep working and do my job as good as possible with what I have in my hands," he added.
"It's not an excuse, we just try to work hard. Everyone has limitations, we have ours, and we'll try to work around it.
"Then, whatever happens next year, I don't know."
