Hello, there is no lock mode, does the car start? the C most likely is the service due if you can send me a photo of the dash i can confirm this.

please elaborate on what the car does and does not do.

also at any time were the jumper cables accidentally hooked up backwards? or wrong?

Customer: replied 7 months ago.
The car starts but I can't take it out of park and into driver or reverse. It's a 2016 cla250. Don't worry about the c. It's just that it's in comfort setting.

OK, lol, that was the other option. so when you press the brake does the brake lights come on?
