United States Grand Prix practice pacesetter Lewis Hamilton says he is confident that he won't suffer a repeat of a hydraulics problem which hindered his running at the Circuit of the Americas.
Hamilton edged out Mercedes team-mate Nico Rosberg by just 0.003s but spent the final 15 minutes of the session in the garage after his W05 Hybrid developed a mechanical issue.
"The car felt good today and we were able to improve consistently over the two sessions," he said.
"I only got a couple of laps of my long run which was unfortunate as we lost a bit of track time but Nico got the data for the team so we should be okay. I'm not sure exactly what the problem was and we had to stop as a precaution but I'm sure they will identify and fix it overnight.
"These small glitches happen and I'm confident that we won't have problems moving forward. It's better that it happened today rather than later in the weekend, of course.
"It looks very close with Nico out there and I'm expecting a very tough battle this weekend. I love being here and it's great to see so many fans around the circuit already, so I'm excited for the rest of the weekend and feeling ready to put on a show for them."
Rosberg added that he was concerned by Hamilton's problem.
"Between Lewis and myself, the times were very tight as usual," he said. "But it was worrying to see that Lewis had a problem with his car as it shows that our car is still not 100% robust at the moment."
