The Australian edged out teammate Sebastian Vettel to form a Red Bull one-two on the front row of the grid, but Webber has insisted that tomorrow is the main day to perform.
Webber told reporters: "I'm happy to get the job done reasonably well.
"We did it when it counted and that is what it is all about. I'm happy to start on pole but tomorrow is the main day.
"We felt that we had a good car but we never get ahead of ourselves. We came here knowing it's not going to be a given."
Webber is in fifth place in the Formula 1 drivers' rankings.
