Lewis Hamilton says he will try to win Sunday's Brazilian Grand Prix despite starting second and the fact he has a substantial lead in the championship.
He has a 24-point lead over team-mate Nico Rosberg, who starts from pole, and can take the title with third here and second in the last race.
"I'm here to win. Nothing really changes this weekend," said Hamilton.
"I don't particularly think I have been taking risks in the last few races. I will apply the same approach."
Hamilton has won the last five races, to turn around what was a 29-point deficit to Rosberg after the Belgian Grand Prix in August.
The Englishman said he was confident despite qualifying behind Rosberg - by just 0.033 seconds - and the German appearing to have had a slight advantage all weekend.
"It's generally been a good weekend," added Hamilton, ahead of the race which starts at 16:00 GMT.
"I've been very happy with the performance. Nico has been very quick. I've just been chipping away at it.
"Qualifying was quite close. There are some potential issues I have to sit with the engineers and try to understand what they are but generally for the race it should all be fine.
"We've got no problems and the car has been great all weekend. I'm really excited.
"Even though we're starting second, qualifying was really good fun and I'm looking forward to having a fight at least."
Hamilton had to overtake Rosberg to win the US Grand Prix weekend, but said: "Even overtaking Nico last weekend was quite straightforward textbook stuff."
He added: "This is a track where it is very hard to overtake. Nico is quick in the long runs.
"We have the exact same car so it is going to be very hard to do any overtaking. There might not be any opportunities, but we'll find out."
Rosberg's pole was his 10th of the year, which means he has won the pole position trophy, which has been introduced this season.
He said: "In Austin there were some things I needed to do better. Here there are many things in my favour.
"First of all we practised for the race a lot more, including this morning in P3 [final practice] with a lot of fuel in conditions that are going to be more similar to the race so that is going to be very helpful. And I felt comfortable so that's good.
"In Austin it was just finding the rhythm quicker and it took me too long to get into the rhythm and anyways it's a different situation and a different track. Everything's different."
|Hamilton v Rosberg for the title|
|Hamilton has a 24-point lead over Rosberg with a maximum of 75 points remaining - 25 in Brazil for a win and 50 in Abu Dhabi, so the world title cannot be decided at Sunday's Brazilian Grand Prix.|
The track at the historic Interlagos venue in the heart of Sao Paulo has been resurfaced this season and it is causing high tyre wear and teams are expecting an unpredictable race with at least two pit stops.
