Sebastian Vettel's disastrous Canadian Grand Prix Saturday might be about to get worse as he has been summoned to the race stewards to explain his conduct in FP3.
Vettel was spotted overtaking the Manor of Roberto Merhi during one of the red flags in Saturday morning's Free Practice 3 session – which limited the running for all drivers.
"Obviously there was a red flag at the time, I was behind the Manor and I don't know what was the problem with him, he was quite slow and I passed him," he admitted.
Before his energy-recovery system problem struck in Q1, Vettel was confident of taking the fight to the Mercedes duo.
Teammate Kimi Raikkonen qualified third, behind the Mercedes of Lewis Hamilton and Nico Rosberg.
"I think today would have been okay, I was happy with the first lap [in free practice before the red flag].
"We know that Mercedes turns it up in qualifying, so what we see on long runs does not count for qualifying. We know they are quick, so I don't think it was a surprise."
Vettel then had to leave his press interview to see the stewards along with team manager Massimo Rivola.
Merhi was summoned as well.
