Sebastian Vettel took to the top of the timesheets for Friday morning, steering clear of his occasional practice wobbles to finish less than a tenth of a second faster than Jenson Button. Adrian Sutil led the way for a while but dropped to sixth after the soft tyres were bolted on. Sébastien Buemi had to sit out most of the session after just three installation laps and without setting a time due to some kind of leak on the Toro Rosso.
