Button says he doesn't expect a repeat of the Red Bull one-two at the British Grand Prix at Silverstone on Sunday.
Button had to make do with a disappointing sixth place while Brazilian Rubens Barrichello bettered his British team-mate by finishing in third spot.
Vettel's victory means he is just two points from Barrichello in the F1 championship, although still trails Button by some 23 points.
In the race, Vettel was some 0.4 seconds faster than the Button. In qualifying the German strolled to pole position in a car that had benefited from new aero updates.
Playing down the advantage of Red Bull's new aerodynamic improvements, Button said: 'Their new aero package has helped them a lot but I don't think the advantage is as big as it looks.'
Button and Brawn believe the Red Bull had the advantage at Silverstone because cooler temperatures prevented the Brawn car's tyres from heating up to their optimum temperature.
The Brawn team is now hoping for warmer temperatures in Germany on July 12, but Red Bull boss Christian Horner says the Silverstone victory represents the shape of things to come. 'A car that works well here should be quick at all the remaining circuits,' he said.
