HELP FOR MG HS PREV STARTING WITH COMBUSTION ENGINE

[jujomase]

Hello, I would like you to help me if you know, how I can start the car with only the petrol engine, it is to do a gas test as they do in the MOT.
Thank you.

Turn the heating up will start the engine and will override the EV button.

Yes, but this option doesn't work because it stops after a while...
thanks

Have the bonnet open I think I see this at the dealership when having the car serviced.
