"I'm in the frame of mind that I still have races to win and the job isn't done yet," the British driver said during a press conference in the paddock of Sao Paulo's Interlagos circuit, where the Brazilian Grand Prix will take place on Sunday.
After clinching his fifth title in Mexico, Hamilton said his goal was now to make sure "we secure this title in the next two races for the team," referring to the Brazil event and the Abu Dhabi Grand Prix.
"That's the key, because, as we always talk about, there are over 1,000 people back at the factory that work so hard and that is the one that means most to them," Hamilton said.
Mercedes lead the race for the constructor's crown with 585 points, 55 more than their closest rival, Ferrari, who need to claw back at least 42 of those points at Interlagos to remain in the running.
Hamilton said his team is stronger that last year and that the feeling within the car is better compared to last season.
'I'm in the frame of mind that I still have races to win and the job isn't done yet,' said Hamilton.
