Pole-sitter Sebastian Vettel Saturday said he hoped to get off to a smooth start at the Indian Grand Prix after a slow getaway meant he had to scrap for victory in Japan.
Vettel, who only needs to finish fifth to seal his fourth successive world title, said an over-aggressive start two weeks ago at Suzuka cost him and his team-mate Mark Webber.
The two Red Bulls were both slow off the front row and they trailed Lotus's Romain Grosjean for much of the race before Vettel finally took the chequered flag for victory.
"I think we've been a bit too aggressive, too much wheel-slip and the guys behind us had a better start," said Vettel at Buddh International Circuit.
"For sure we will try to do better tomorrow. I think the starts that we had before that (Suzuka) were pretty good. Korea, I had a very good start.
"So we know how to do it, we just need to get it all right."
Vettel said he would warm up for the race, as usual, by listening to music in his headphones -- but denied Nico Rosberg's tongue-in-cheek suggestion he was tuning in to Canadian pop singer Justin Bieber.
"It's not really... it's music, yes, but it's more like melodies, no singing, so no Justin Bieber. I think that was on your iPod," he told the German driver.
"In the end, it's not a secret, it's just music that gets me or tries to get me in the zone so that I hopefully get the best out of myself."
