Red Bull may have wrapped up the constructors' title in the United States on Sunday, but Ferrari and McLaren are still going head-to-head for second place and bragging rights given their history.
Crucially, with a total prize fund of just over £400million available to the 12 teams in the constructors' championship, the difference between finishing second and third equates to around £10million.
With Ferrari 14 points ahead of McLaren going into the final race of the year in Sao Paulo on Sunday, for the latter there remains plenty at stake, even if they no longer have a say in the title fight.
That was evident by Button's frustration in Austin in which he finished fifth behind race-winning team-mate Lewis Hamilton.
Speaking to Press Association Sport, Button said: "We scored good points in Austin, with Lewis picking up a maximum.
"But it was still a little bit frustrating because we didn't gain as many points on Ferrari as we should have done - we're 14 behind them now - which is still quite a few.
"We took eight points off them in Austin, so we need to almost double that in Brazil, and I think we can do it if we both have a perfect weekend. That has to be our aim for the end of the year.
"Even though we can't win the constructors', second place still does mean so much to the team.
"It's a lot of money, and this is the team I race for, so it does mean a lot for the future.
"Also, you always want to get one over on Ferrari. You want to finish in front of them, that's the way it is.
"We're competitive, and although we can't beat Red Bull, we've a chance of beating Ferrari.
"So we'd love to win, which would finish the year on a massive high, with Lewis winning in Austin, and I would love to win in Brazil."
Interlagos is a circuit where Button has never previously won, so he has a score to settle and is eager to avoid the scraps he has become embroiled in of late.
In Austin, Button was forced to battle his way from 17th at the end of lap one after starting on the harder compound tyre, which proved to be a wise move come the conclusion.
But it was hard going, and not an experience he wishes to repeat, adding: "Sunday was a great race.
"The whole team and Lewis were able to show how good the car was, and just what a good job we can do.
"It's just a pity for me that in qualifying we had the problem we did because the pace was definitely there, even on the hard tyre, which was amazing.
"It was really, really good fun, despite the start when I fell back to 17th, but I fought my way through, I had some really good fights with people, with most of them very clean.
"It was great racing out there. I don't think we could have had a better race in the States for our first race back.
"But despite having fun and overtaking more cars than I think I have done all year, I don't want to do that again.
"I've had enough of fighting and overtaking. I just want to race from the front."
