The Briton was nudged into a crash at the final corner of the opening lap of the Silverstone race two weeks ago when he tried to go around the outside of Binder.
Binder was handed a long-lap penalty for the incident, while Dixon was unable to re-join.
After the incident, a heated Dixon slammed Binder on TNT Sport, branding him a “clown” and calling for him to be banned by the stewards.
On Friday at the Austrian GP, however, Dixon rolled back on his comments and apologised to both Dixon and the Intact GP team.
“Silverstone was not ideal, and first of all I want to apologise to Darryn Binder for my words because they were not on and I just did not do it in the correct way,” Dixon said on TNT Sport.
“I didn’t want to talk at the time and I want to apologise to him and his team because I was outspoken on that and it was not good and it didn’t look good either. So, I apologise for that.
“We’ve got 11 races to go, anything is to play for. We need to just keep our heads down, and see what happens because you never know what’s going to happen in this championship.”
