My driver assistance features are turned off?

Hi all,

My mother-in-law has an MY23 MG HS and she was complaining today that the safety features are all turned off, as a repair man has told her nothing is working and he can't figure it out.

Anyway, I would like to know if anyone has knowledge about turning the cruise control, lane assist, etc. back on. Otherwise she said she will take it back to MG however I don't want them charging her for an easy (?) fix.
