Button eyes error-free race in Brazil

The British driver finished Sunday's Japanese Grand Prix in eighth position to see his championship lead stay on a healthy 14 points from Brawn team-mate Rubens Barrichello with just two races remaining.

Red Bull's Sebastian Vettel, the dominant winner of the Suzuka race is 16 points behind.

Button needs to finish in third position in Brazil to secure his first title, regardless of what his two rivals do.

The championship leader made it clear, however, that his main goal will be to have an error-free weekend and pick up as many points as possible.

"Well, it is all about mistakes," Button told reporters after the Suzuka race. "With them they had a very fast car and for whatever reason they did not finish races. It is about finishing races and picking up points.

"We obviously want the best result possible, which is to win races, and we will get as close as we can. But it is about not making mistakes, that is the most important thing."

He added: "Whatever happens in Brazil I will have a four-point lead. So, I lost a point today which is frustrating because my pace was very good compared to Rubens.

"But I started a long way behind him, so losing one point is not so bad. And it is seven points per race rather than five points per race that he needs to be beat me by. So, it is not a bad position.

"I go to Brazil positive and looking forward to the challenge, because it is going to be a challenge. Sebastian is quick and the Red Bull seems very quick.

"It has still got high-speed corners, and they have showed they are quick on low-speed corners like Singapore, so they will be difficult to beat. And Rubens is always quick there - so it is going to be a challenging weekend, but a fun weekend as well."

Button's Brawn team all but secured the constructors' title at Suzuka, the Brackley team needing just half a point to be out of Red Bull's reach.

The Briton said the team has every reason to be proud this year.

"I feel it will go our way when we go to Brazil, then everyone should be very, very proud of themselves in this team," he said. "They have been through a lot. It has been a rollercoaster throughout the season but also last winter, so if it does happen then congratulations to everyone.

"It is going to be a very emotional moment for them, if it happens here. And well done to Ross Brawn - he has achieved a lot in his Formula 1 career but this is very different from being a team owner.

"Also, after such a difficult winter, we didn't even think we would be on the grid in Australia so to come away with a victory there, and many victories this season, then to come away with the constructors' title will be a very special feeling. But we will wait and see."
