Esteban Ocon and Sergio Perez have been reminded of their duty to the team ahead of the Austrian Grand Prix.
The Force India duo have hindered each other's races in both Canada and Azerbaijan, and team principal Vijay Mallya has urged for these "unacceptable" incidents to stop.
'It's still frustrating to ponder what might have been had things played out differently,' Mallya said in Force India's race preview for Spielberg.
"Since Baku we've had some conversations internally and reminded our drivers that the team must always come first.
"It's never acceptable for teammates to make contact with each other and it certainly cost us points in Baku.
"However, the events of Azerbaijan won't change our approach.
"Our drivers can race freely and I am sure they have learned some valuable lessons … I know they are mature enough to work together for the good of the team."
Force India are currently fourth in the Constructors' Championship, 89 points behind Red Bull in third.
