Rio Haryanto will race for Manor at the German Grand Prix but has said his future beyond that may well hinge on securing sponsors during F1's summer break.
Haryanto's future beyond the Hungarian Grand Prix had been uncertain, with his initial contract believed to cover the first 11 races of the season only. The Indonesian driver found out on arrival on Tuesday that he would remain in the car for this weekend's race at Hockenheim.
F1's four-week summer break follows the race in Germany and Haryanto thinks that gives him the perfect opportunity to secure funding for the second half of the season.
"It was a little bit uncomfortable but I am very pleased to be back here at the Hockenheimring and everything is fine now to go racing," he said. "I am very confident because the contract has always been a one-year contract.
"I am confident over the summer break we have three weeks when there will be potential more sponsors coming and there are also races closer to my home country and there will be interest for potential sponsors."
The Indonesian driver is happy leaving the matter in the hands of his management.
"My management is working very hard and I believe in them a lot, they bring the best that they can, also the team has been very supportive of me, and the fans. They're trying their best to keep me in Formula One."
