Weather forecasted that condition will change in Saturday qualifying and Sunday race for the Australian Grand Prix. Because the reigning world champion played down that changing conditions could make Friday's results unrelated.
"I have to say it was a very good day for us," Vettel said.
"Surely one thing is to look at the timesheets but that's not the important thing today. For sure it feels good to know that you're kind of up there somewhere but I have to say it was a very good day considering it was the first day of the season; we didn't have any problems, no major dramas so it was a very quiet day and we got through the programme so I'm very happy with that."
"We know a little bit more than yesterday, that's for sure, but I think we have to be aware of the fact that conditions can change.”
“A couple of degrees make a massive difference with these tyres so for today I think we are very happy but tomorrow could be another day so I think there's room for improvement and we need to keep our eyes open and see what happens.”
"When we arrived it was very hot and since then it's got cooler. How much that has an impact on tyres and how they work and car balance we can't really predict but we need to be ready to change. Even though today was a good day - I was happy with the balance - the conditions will change so we need to be aware of that and switched on to make the right choices."
"I think better than in testing. We kind of expected that because it's a different circuit but the soft tyre surely doesn't last that long. We saw that people came in and went back on the hard tyre, but I think the hard tyre should be a decent race tyre. For qualifying, for sure, it's all going to happen on the soft tyres."
