I'm confused on how to put the car in accessory mode where the infotainment/radio can be used. I know the manual says to push the power button without pressing the brake pedal. Sometimes it works and sometimes it puts the car in ON mode without driveability. The ON mode is similar to not cranking the engine to start it. The battery and engine lights are ON and the fan blows. Someone once told me that I shouldn't leave it in that state without the motor running.
