Charlie Whiting, Formula One's race director, will warn teams over their future pit lane conduct following Mercedes' 'dummy' stop during Sunday's British Grand Prix.
Mercedes sent their mechanics into the pit lane in a deliberate attempt to unsettle Williams who led the opening phase of the race at Silverstone.
The FIA rulebook states: "Team personnel are only allowed in the pit lane immediately before they are required to work on a car and must withdraw as soon as the work is complete."
But Mercedes motorsport boss Toto Wolff admitted afterwards:''We know Williams has difficulty keeping the tyres to last and we knew that taking an early pitstop might trigger them into a pitstop that would cause them problems. It was a bit of a game that didn't work."
While Mercedes avoided any punishment at Silverstone, Whiting has said that he will speak to the teams about the ruling ahead of the Hungarian Grand Prix later this month.
"Going into the pit lane like this, ie for no valid reason, is not allowed but the difficulty would be proving it was a clear breach," Whiting said.
"I have no intention of giving them a few chances and will talk to all the teams - at the next race in Hungary - about this and warn them that we will want to see and hear evidence that they were actually intending to stop."
Wolff also said that his wife Susie, the Williams reserve driver who celebrated wildly as Felipe Massa and Valtteri Bottas leapfrogged pole-sitter Hamilton and Nico Rosberg off the start-line, sent him a message during the race.
"My wife sent me a text that said, 'You guys think you can fool us, ha, ha, ha.' At least it was a bit of entertainment.''
Hamilton won the rain-hit race ahead of team-mate Rosberg. Massa and Bottas finished only fourth and fifth despite heading the field before the first round of stops.
