With the 2008 world champion's contract expiring, he told the Russian news agency Ria Novosti on a weekend visit to Russia that he is gearing up to talk with McLaren about 2013 and beyond.
"We haven't sat down and discussed anything yet but I'm sure over the summer break, when we have the summer break it would be nice to get something in place," said the Briton.
There have been rumours about Hamilton's alternatives beyond 2012, but he indicated that a new deal with McLaren is likely.
"These people have supported me; these are the people that got me into Formula One," he said.
"But, you know, I want to win. I'm not that young any more so I want to make sure that whatever I do I make the right decision so I can maximise my career, you know. I just need to make sure that I'm winning."
That note of warning coincides with a performance slump for the famous British team, but Hamilton indicated that he will look beyond the most recent disappointments.
"To be honest, you have to base your decisions on much, much longer than such a short period of time," the 27-year-old said.
"Only half a year cannot decide six years of partnership, or actually 13 years of partnership. I've been with them since I was 13, so it's 14 years, so it's much more than these small details, it's a much, much bigger picture."
