Heikki Kovalainen lamented traffic on his final run in Q1 that left him down in 20th place.
The Finn spun exiting Turn 10 and beached his Caterham in the gravel.
"There was more to come but I had a bit of traffic that held me up and then on my second run I caught up with a bunch of cars going into turn 10 and lost a bit of grip, enough to put me off", he said.
"I wasn’t going in too hard and there weren’t any issues with the car, I just lost the front end and even with the spin I didn’t lose any positions so I think we can still have a good race tomorrow".
Team mate Vitaly Petrov is confident ahead of the race.
"I’m really happy with where we finished up today. All weekend the team has done a good job and I’ve had a balance I’ve been happy with in every session", said the Russian.
"We made a couple of changes for quali and the way the car felt and my laptimes showed that we made some progress, so I’m pleased with that. Now we’re looking ahead to tomorrow and to be honest anything could happen. Nobody’s too sure what tyre strategies will be run, it could be one stop or two, so we’ll look at that tonight and I’m pretty sure that if we make the right choice we could have a decent result in the race".
