The German ace piloted his Red Bull to a third consecutive world title in the final race of last season in Brazil, pipping Ferrari’s Fernando Alonso by just three points.
It was the second time in the past three seasons that the Spaniard had been denied by the young German for the world championship in the last race.
Vettel, 25, is bidding to become the youngest driver to win four world titles in a row, a feat only achieved by Formula One legends Juan Manuel Fangio and Michael Schumacher.
Vettel is again the hunted favourite after three years in the fastest car produced by Red Bull.
“The secret is not to think about what happened in the last three years. I think the first title was very special,” he said.
“After that you don’t have that pressure any more. You’ve proved to yourself more than anyone else that you can do so,” he added.
Vettel said that past glories meant little as the drivers embark on the new season.
“We are here, we have zero points at the moment, the same as everyone else. Everyone has the same opportunities, the cars haven’t really changed,” he said.
“Last year we saw it was very close, so I don’t expect it to be any different than last year, if anything even a bit tighter, so it will crucial to make the most out of every single race,” he remarked.
