"I have a contract here and I am working on the assumption I will see it out," said the 66-year-old, who has a deal in Munich until June 2013.
Bayern said Wednesday they are looking at their legal options after German daily Bild reported he is set to leave in May, but Heynckes said he is ignoring any negative reports.
"They don't bother me, they don't weigh me down," he insisted.
With two months and ten games left this season, second-placed Bayern are seven points behind leaders Borussia Dortmund in the German league.
They must also overturn a 1-0 deficit against FC Basel on Tuesday to reach the last eight of the Champions League in the home leg of their Round of 16 clash.
Bayern's fortunes have taken a nosedive since Christmas with just four wins in their last nine games and Heynckes admits it is an "unsatisfactory situation".
"I am energetic and feel relaxed. I carry out my job with a passion. I know that we can turn the tide," he said ahead of Saturday's Bundesliga clash at home to Hoffenheim.
Bayern were beaten 2-0 at Leverkusen last Saturday, but Heynckes says after a week of good training his team will perform at Munich's Allianz Arena both on Saturday against Hoffenheim and next Tuesday against Basel.
"We have had a very good mood in training which we will show on Saturday and Tuesday," he said.
"I am convinced we know how to win and deal with the pressure."
Even though his side are lagging behind Dortmund in the league, Heynckes said his team still have everything to play for.
"We haven't written anything off, has the title been decided after only 24 games?
"It will be settled at the end of the season."
Heynckes' hopes of improving Bayern's fortunes received a boost on Wednesday when Germany star Bastian Schweinsteiger returned to training after tearing ankle ligaments at the start of February.
