Hello, I can recall there was previous discussion on how to turn off the car, but leave the radio running. Some people figured it out with the CVT Fit, but has anyone figured out how to do this with the manual Fit?

 

Without clutch engaged, hit the start/stop button-- look at pages 117-120 of your manual for diagrams and explanations of modes.

 

with my 6mt fit, i have not been able to shut the car off, and leave the acc on with one button press. turning it on, sure i can go into acc mode, with one button press, but not turning it off.

 

Interrupt the spark.

 

But that is to put the car into accessory mode with it turned off. I'm talking about putting it into accessory mode when the car is ON (without turning it off first).

 

No unfortunately you have to shut the engine down first. Then lightly press the start button to cycle through acc,on positions.

 

Correct-- diagram in the manual (page numbers above) shows how to move through modes (and that one can't go from "on" to "accessory" with the start/stop button). Misread the initial question that OP was trying to go from "on" to "acc."
