Jenson Button is delighted he will start the Austrian Grand Prix from third on the grid, but is unsure his McLaren will be able to maintain that position in Sunday's race.
Button was a season's best fifth fastest during Q3 at the Red Bull Ring on Saturday, and grid penalties for Sebastian Vettel and Nico Rosberg provided a further boost by promoting him two places.
The 2009 world champion was pleased with how McLaren performed in varying conditions and expressed his pleasure at securing a place on the second row.
However, he admitted making the position stick during the race could prove difficult.
"It was an enjoyable session. I thought it was all over in Q2, I locked up into turn three but I just stayed in and we called it right in the end," Button told Sky F1.
"On the wets we were quick and on the drys we weren't bad either. Some of it is just the way I drive.
"There are conditions when I can't get the best out of the car and there are conditions when I can. Really happy to start third, just a pity I'm not in the press conference!
"It worked out today, a lot of time it hasn't this season but it did today. I'm not too sure I can hold but we'll see what we can do."
Nico Hulkenberg was third fastest but will start from the second due to Rosberg's penalty, although the Force India driver felt he could have done more.
"I was feeling really good in the car, I was expecting a little bit better than third to be honest," said Hulkenberg.
"But I wasn't disappointed, the car performed well, and we've got a very strong starting position tomorrow."
