Heinz-Harald Frentzen will reprise his 2010 stewarding duties at this weekend's European Grand Prix.
The German made his debut in the FIA role at the same Valencia street circuit last season.
Now 44, Frentzen won three Grands Prix during his 160-race career between 1994 and 2003.
He drove for Sauber, Williams, Jordan, Prost and Arrows, and subsequently for Opel and Audi in the German touring car series DTM and then sports cars.
Frentzen currently races a Corvette GT3 in the ADAC GT series.
