Canadian GP: F1 stewards summon Sebastian Vettel over red flag move

Vettel admitted he had passed a Manor during the second Saturday morning stoppage, but did not feel he had done anything wrong.

"There was a red flag at the time, I saw the Manor; I don't know what the problem was with him, he was going quite slow and I passed him," said Vettel before heading to the stewards' office.

It comes on a disappointing day for the four-time world champion, who failed to make it out of the first part of qualifying.

He came back to the Ferrari pit after his out-lap with a lack of power, and efforts to rectify it proved unsuccessful.

Vettel was sent back out in the hope he could still make it to Q2, but was only 16th fastest.

"We had problems where we couldn't get the full power so obviously we were losing a lot on the straights, which is a shame," said Vettel.

"We tried to get into to Q2 and maybe buy us some time but it didn't work and in the end it wouldn't make a difference.

"I don't think it's anything to do with the engine. It's more the electronic side.

"I'm sure we can fix the problem and then we can have a good race tomorrow."

Ferrari had high hopes for a strong result this weekend after it used three of its engine token allocation for an upgrade ahead of the Montreal race.

While team-mate Kimi Raikkonen qualified third, behind the two Mercedes, Vettel will start 15th after Max Verstappen's 15-place penalty is applied.
