Jenson Button has vowed to maintain his 'steady Eddie' approach as he closes in on the Formula One world title.

With a 15-point cushion over Brawn GP team-mate Rubens Barrichello with three races remaining, Button can wrap up the championship in Japan this weekend.

Button simply needs to bag five more points than the 37-year-old to take Lewis Hamilton's crown, although that is a feat he has failed to achieve for the last seven races.

It means the 29-year-old Briton will not head into Sunday's race in Suzuka with all guns blazing in a bid to wrap up the title at the first attempt.

Button said: "People say if I finish five points in front of Rubens I can win the championship.

"I know that's a fact, but my aim is to win the world championship and I'm not going to take any unusual risks.

"I'm just going to drive like I have been and hopefully that will be enough."

Following a storming start to the season with six wins from the opening seven races, Button has been on the podium just once in the last seven grands prix.

His recent form has led to suggestions of a lack of aggression, of nerves, of Button merely being content to stumble over the line.

Button, though, maintains the rest of the grid has caught up, and there is now more of a level playing field.

"Anything can happen," Button told autosport.com.

"It's just an unusual year where there are so many cars that are competitive whatever the conditions.

"There are so many different possibilities of teams being quick, so it makes it very difficult when it comes to strategy.

"We know we have to beat the Red Bulls, but that's why you see us sometimes at the front fighting for wins, and other races we are not.

"The important thing is to make the most out of the good times, but also the difficult times.

"When it's difficult you need to pick the points up and that's what I have been trying to do."
