Jenson Button is 14 points clear in F1's title race with two races left
By Sarah Holt
BBC Sport in Sao Paulo
Britain's Jenson Button says he will be happy to adopt a cautious approach at the Brazilian Grand Prix on Sunday, with the world title within grasp.
A podium finish would seal the title for Button but the 29-year-old, who holds a 14-point lead, said he would not take any unnecessary risks.
"It's different for those chasing, they have to be more aggressive," he said.
"I don't want to just finish in the points - but there are situations I don't want to get myself into."
For the second race running, Button has a chance to clinch a maiden world title and close the door on his Brawn team-mate Rubens Barrichello, who is 14 points behind, and Red Bull's Sebastian Vettel, who is 16 points adrift.
While Barrichello and Vettel must significantly close the gap on Button if they are to keep the title race alive until the final race of the season in Abu Dhabi, Button just has to maintain the lead he has held ever since Australia's curtain-raiser. "This is not a one-race series," insisted Button, who won six of the first seven races.
"It is about 17 races and I've kept the lead, so I'm not in such a bad situation.
"It's been a long time since the title hasn't gone down to the wire and it would be better if I won here, but we still have another race in hand.
"Now it's about keeping it simple. I'm not coming here thinking about how many points I need to get. It's about me staying relaxed."
Button has not won a race since June's Turkish Grand Prix and 1996 champion Damon Hill insisted after the Japanese GP that Button needs to "raise his game".
But Button has put the onus firmly on Barrichello and Vettel, as the trio all vie to get their hands on a first world title.
"We are all fighting for something that is far greater than we have achieved in the past," Button added.
WORLD TITLE RACE IN A NUTSHELL
Button will win the title in Brazil if...
He finishes third or better
OR He finishes fourth and Barrichello does not win
OR Vettel finishes lower than second and Barrichello finishes lower than fourth
OR He loses no more than four points to Barrichello
"It is an exciting situation to be in, but I am the one with the lead.
"I woke up with a smile on my face. I don't think it adds to the pressure, knowing that you could win the world championship; it adds to the excitement.
"I haven't purposely gone out to finish in the points and not win races. We have a few upgrades that should help us here and so I am optimistic that I have the resources to do well here and to score a good result."
Barrichello is also hoping Brawn's updates will also benefit his title charge in his hometown of Sao Paulo.
The 37-year-old has a relatively poor record at Interlagos, where he learnt his trade on the kart circuit in his youth, finishing a career-best of third for Ferrari in 2004.
"I've been dreaming of winning here for a long, long time," said Barrichello, who needs to out-score Button by at least five points on home soil.
"Hopefully I can win because I need it and I want it so badly. I have all the possibilities to have the best race of my life and that is what I plan to do."
Button and Barrichello need just a single point between them to claim the constructors' crown for Brawn this weekend irrespective of Red Bull's performance.
While the pair, who have been team-mates for the past four seasons, are happy to work together to bring some silverware to Brackley, both insist it is every man for himself when it comes to deciding the drivers' title.
"Hopefully we will win the constructors' title here," said Barrichello. "But in the other championship we have to work for ourselves for the win.
"Like Jenson said, we don't want to lose the chance to win the title; for me it feels like it is my very first chance to go and get it for myself.
"But it feels comfortable that we are working hard to beat each other and working well for the constructors' - the team should be proud of that."
Button added: "Rubens and I are friends but we're fierce competitors on the circuit.
"If Rubens won the title I would be very disappointed but I would also respect the fact that he did a better job over 17 races than me, that he worked as hard as I have and that he is the better driver."
"The pressure is on the two in front of me
Red Bull's Sebastian Vettel
The third title contender, Vettel, must take first or second place in Brazil to retain his slim title hopes.
The 22-year-old was a convincing winner two weeks ago in Japan and is again expecting his car to be competitive, with the forecast wet weather likely to suit the Red Bulls.
"The only thing I can do is to win," Vettel said. "The pressure is on the two in front of me.
"You don't have to be a genius to know that I have to win the races and those two mess it up.
"The last two races were very good for us and this circuit should suit us; it has a lot of corners where you need downforce and that seems to be our strength."
Whether Vettel is able to stay in the title hunt after Sunday's race or not, he insists he will not rue his missed chances this season despite failing to finish five races.
"I have nothing to regret," he added. "It doesn't help looking back.
"We can still do it. There are a couple of points between us and the leaders but anything is possible and we are here to win."
