Lewis Hamilton says he takes "zero comfort" from the 17-point lead he holds over Nico Rosberg in the drivers' championship with one race to go.
Hamilton only needs a second-placed finish in Abu Dhabi, where double points will be awarded, to clinch a second world title.
"There is zero comfort going into the next race," said the 29-year-old.
"There are 50 points to gain. The last race, you never know what's going to happen, so I'm going there to win."
Hamilton finished second to Rosberg in Brazil on Sunday, with the German's first win since July ending his team-mate's run of five consecutive victories.
In total, Hamilton has won 10 grands prix this season to Rosberg's five, but, with 50 points on offer to the winner of the final race, the Briton could yet be beaten to the title.

Despite the double points potentially working in his advantage, Rosberg said he finds the innovation "artificial and I don't like it in general", but Hamilton remained open-minded.
"We need to keep on reviewing it," said Hamilton. "It's good to try something and we'll see how it goes this year.
"The important thing is that the fans are happy. We need to see if we keep on doing it or change."
Asked whether he had ever considered that he might not win the title, Hamilton said: "No. Why would I think that? It's not the way to approach any race weekend."
Hamilton closely challenged Rosberg in Sao Paulo, finishing right behind the winner despite a spin that cost him seven seconds.
"Today showed I used my tyres better than anyone I have raced with up until now," continued Hamilton.
"And I used them better today than Nico. I was always behind, so I was always in his dirty air, scrubbing the life out of the tyres, but still staying with him.
"And when he pitted I had extra pace. There are a lot of positives to take from today."
