Toto Wolff says Mercedes will act to prevent the first corner clash between its two drivers at the U.S. Grand Prix flaring up ahead of the final rounds of the season.

Nico Rosberg was forced wide at Turn 1 after Lewis Hamilton attempted a move on the inside that resulted in the cars colliding. Rosberg made clear he felt Hamilton had gone "one step too far" with the move, although the incident had little bearing on the end result, which saw Lewis Hamilton take victory and the title after Nico Rosberg threw away his chance of winning the race with a mistake between Turns 12 and 13.

Nevertheless, team boss Wolff said the collision would be discussed once the title celebrations die down.

"It is also a crucial moment now to make sure today's race and this incident don't release consequences within the team and splitting the two sides of the garage," Wolff said.

"It's very hard. Lewis came on the radio and said it wasn't on purpose, I think it's something that we are going to talk about in a couple of days, but this is the moment to celebrate a world champion who deserves to be a world champion and once the emotions have cooled down we will discuss."

The last time Hamilton and Rosberg clashed on track was at the 2014 Belgian Grand Prix, which brought to a head a season of tension and resulted in a series of post-race meetings to diffuse the situation. Wolff admitted Sunday's collision could have similar repercussions if Mercedes does not soothe the relations between its drivers.

"If we don't take any action it has the potential [to be like Spa]. It's never easy and it wasn't easy the first time around. I think we have some experience and we just need to have a calm approach and a firm approach of how we would like them to compete."

Asked if Rosberg may start treating Hamilton differently, Wolff added: "That danger is for sure imminent."
