Each driver pointed the finger at the other over the incident, which cost di Resta several places and a shot at finishing higher than eighth.
Deputy team principal Bob Fernley plans to stress the need to work as a team.
"We just need to sit them down and go through the video because it's not really what we need to be doing on the first lap," Fernley told AUTOSPORT.
"They are both good enough, and just need to sort it out between them.
"I don't think it's difficult to manage it, we just need to make sure they clearly understand that it's not acceptable, not on the first lap."
Fernley was unsure as to who was responsible for the coming together, having not had the chance to study the footage when asked about the clash.
But he suspected that Sutil should have given di Resta more room.
"You can have things happen when you get pushed into positions [that you don't want to be in] and we need to understand it fully ourselves," he said.
"But I suspect that Adrian got catapulted off the kerb, something like that happened so he didn't give Paul enough room there."
Fernley added that the damage was limited by di Resta's strong recovery drive.
But he believes that the team could have finished as high as fifth without the clash.
"It could have cost us more dearly, but fortunately it was a good, well-run race," he said.
"It was a hard race, but we managed to pull Paul back through and the strategy worked.
"We targeted seventh, and without the first lap incident we could have got Jenson [Button] as well."
