Rosberg clashed with Formula 1 title rival Hamilton in a fight for the lead at Spa-Francorchamps in a move that Mercedes chiefs say was unacceptable.
And although Mercedes will wait for the dust to settle on the weekend before holding a crisis meeting, Wolff has assured Hamilton that a simple telling off is unlikely.

"Today we've seen the limits of the slap on the wrist," he said. "Maybe the slap on the wrist is not enough.
"If Lewis has said that it's going to be a slap on the wrist, and that there's going to be no consequence, then he's not aware of what consequences we can implement."
When asked what the team could actually do to rectify the situation, Wolff said: "A lot. But I'm not going to comment on this right now."
He also clarified Hamilton's comments suggesting that Rosberg had admitted to crashing on purpose "to prove a point", explaining: "Nico felt he needed to hold his line. He needed to make a point.
"He (Rosberg) didn't give in. He thought it was for Lewis to leave him space, and that Lewis didn't leave him space," added the Austrian. "So they agreed to disagree in a very heated discussion amongst ourselves, but it wasn't deliberately crashing. That is nonsense."
