It was a wet first practice with drivers heading out on the intermediate and wet tyres as the pit lane opened and the session began. Three Friday drivers were in session, with Daniil Kvyat in at Toro Rosso, James Calado in the Force India, and Rodolfo González driving for Marussia. Mercedes led the way, in an incident-free session that gradually dried up towards the end. Sebastian Vettel was third, with Jenson Button up in fourth.
