Qualifying follows later on Saturday with the Hungarian Grand Prix, the last before a four-week mid-season break, taking place on Sunday.
Ferrari's Kimi Raikkonen was fourth in both sessions and compatriot Valtteri Bottas, Championship leader Lewis Hamilton's team mate, was sixth before and after lunch.

"We're going to do our best to work as a team [during the race] and keep the red guys behind us".
Vettel reclaimed top spot from Bottas, who then suffered a bigger scare than Hamilton at the chicane.
