Hi! So I own an HS 250h. I've been trying to figure out why the parking assist is non-functional even though it's selected to be on. I combed through the manual to try and find the specific fuse for it to see if that could be the issue, but I was unsuccessful. I have not recently changed the battery, but I did have the feature off for a time. Does anyone have any tips on what I could do to fix it? I would like to try everything that I can first before I take it to the dealership since that's out of my budget at the moment. Thank you very much!
