Rio Haryanto has agreed to remain at Manor for the last nine Grands Prix of the 2016 Formula One season in a reserve driver role.
It has been a difficult first season in F1 for Haryanto, who has endured three retirements in the 12 races this year with a highest finish of 15th at the Monaco Grand Prix.
The Indonesian's future became unclear ahead of the German Grand Prix amid reports his sponsorship money had run out, thus making it difficult for Manor to retain him.
On Wednesday, the team announced Esteban Ocon, a member of the Mercedes-Benz driver development programme, would take Haryanto's seat for the remainder of the season.

However, Manor offered the 23-year-old the chance to stay on in a back-up capacity, and they confirmed it had been accepted on Thursday.
"Manor Racing is pleased to announce that Rio Haryanto will remain with the team for the rest of the season, having accepted its offer of a reserve driver role," an official statement read.
"Rio will be available to deputise should either race driver be unable to take part in an event.
"He will also be immersed in engineering meetings and PR activities, as the team continues its support for his racing ambitions."
