Sebastian Vettel is off the hook after making a series of apologies to Charlie Whiting and the FIA.
F1's governing body had been looking into the tirade of expletives blasted by the Ferrari driver during the Mexican Grand Prix, including telling race director Whiting to "fuck off".
"He did say sorry," Whiting told the Daily Mail.
"He was quite robust about finding me and apologising. Given he has done that I'm not too hung up on it personally, but it remains to be seen how my boss may wish to pursue the matter."
Indeed, Whiting's boss is FIA president Jean Todt, who admitted that after Mexico, an investigation into Vettel's behaviour took place.
However, in a media statement, the FIA announced that Vettel "apologised profusely" in writing to Todt, and also revealed that the quadruple world champion would "be contacting" Max Verstappen after calling the young Dutchman a "cunt".
The FIA therefore decided not to take action against Vettel.
The statement added: "In the event of any future incident similar to the one that occurred in Mexico, disciplinary action will be taken by bringing such incident before the FIA international tribunal to be judged."
The season continues next weekend with the Brazilian Grand Prix.
