Autohold activation

[Kithmo]

I don't think I've had a car in the last couple of decades without this feature. Just press the brake pedal hard when at a stop and it holds the car when you release the pedal. It's for hill starts, mainly.

That's a different feature to auto hold, that's hill start assist which is always on in the MG4, autohold you have to turn on (or off).
Be aware though that hill start assist disengages after two seconds, auto hold stays on until you press the brake or accelerator pedal.
