McLaren's Pedro de la Rosa is refusing to look too far ahead after his return to the Formula One starting grid for this weekend's French Grand Prix.
De la Rosa finished fifth for McLaren in Bahrain last year
The team's test driver was promoted in the wake of Juan Pablo Montoya's move to Nascar, but he is unsure how long he will be in the driving seat.
"I have only been told that I do the next few races and that's it," he said.
"Obviously I want to do all the championship but all I have to do really is look at it week by week."
The Spaniard added: "Being here in Magny-Cours is a major opportunity for me and let's make sure that I don't make any mistakes.
De la Rosa stood in for the injured Montoya in Bahrain last year, finishing a creditable fifth, and he is going to focus on enjoying himself and scoring as many points as possible.
"I don't take it as a last chance," added the 35-year-old from Barcelona, whose last full season was with Jaguar in 2002.
I'm not setting any goals or aims this weekend
"In Bahrain, I took it like it was my last chance and it was not, because here I am.
"I just want to enjoy myself and drive to the limit like I have been doing in testing where I have always been genuinely quick. I want to finish the race and get points," he said.
"I'm not setting any goals or aims this weekend."
There have been suggestions that McLaren could rotate the drive later in the season, with British duo Gary Paffet and Lewis Hamilton also strong contenders.
