Bruno Senna says a measured, realistic approach will be far better than trying to be a hero when he makes his first appearance of the season for Renault tomorrow.
The Brazilian will take the wheel of Nick Heidfeld's car in first free practice at the Hungaroring, his first experience of F1 machinery in six months.
Given that lengthy time out of the seat, Senna says he will give himself time to settle back in and that his main priority is to assist the team by providing feedback on their development work.
"The frame of mind that I have is just to get back into it, there is no point trying to be a hero," he said.
"I need to be realistic: six months and half a season is a lot of time. I know exactly how it feels to be in a car for half a season, and how much easier that makes it to deliver.
"Of course there is pressure because I want to do well, but there is no point trying to operate a miracle here.
"[The goal] is to do a good job for the team to continue their work and development, and make my transition as smooth as possible. I hope to have some fun as well!"
Although Senna has been touted as a potential replacement for Heidfeld should Renault decide to replace the German, he insists that his focus is on securing a full-time seat on the 2012 F1 grid.
"All I want to do is get in the car; of course I want to do that as often as possible, but at the end of the day I'm the reserve driver here and my function is to be the guy who jumps in the car when the regular drivers can't. Whether that changes or not doesn't depend on me.
"I will always try and improve my chances, but my main plan is to get back in a seat next year.
"It depends on the work that I do here and also on potential backing and support from sponsors, which together can create an opportunity, but I'm looking at  especially and hopefully by the end of the year I will know."
