On the S5 the OPD is not defaulted to ON on boot up directly, the preset default mode is normal.
You are able to set your personal preferences of some of the safety features and save them to a custom setting, in order for the car to remember them.
When you first boot up the car, it will default the car to the factory settings.
To enable your own personal preferences that you selected, you have to swipe down from the top of head unit screen and hit the custom button.
Your MG Pilot personal settings are enabled.
However, I have tried increasing the default re-Gen from normal to high, as the boot up preferred option, but it will not save it for the next boot up., which is annoying.
I believe you can set one of the buttons on the steering wheel to bring up the re-gen options and you can choose from there.
Therefore I don’t think it will remember the OPD as he default preference either then on start up tbh.
It’s really odd why MG have coded the boot up default to normal and re-gen 3 on some models and normal and 1 on the S5 ?.
Even stranger that it will not save it, as part of your personal preferences list either.
What is that all about ?.
