Unlike teammate Mark Webber, the 28-year-old German is on a one-year contract and will - speculation says - get the chop if Jenson Button completes his much vaunted switch from BAR back to Grove.
"I don't feel under any pressure," the former Prost and Sauber star told Britain's Evening Standard newspaper.
Until now, 'Quick Nick' has raced knowing that test driver Antonio Pizzonia would take over if he didn't perform.
But Heidfeld, from the go, vowed simply to drive quickly.
Indeed, Nick - from Moenchengladbach - reckons that with a grand prix win in the bag, boss Sir Frank Williams would be loath to dump him.
He admitted: "If you don't perform then you're out. But if I do well I will have no problems." -GMM
