So I am stuck here. I have 2007 Mercedes s550 with 159k miles and have recently started to get the pre safe error randomly on my cluster. Unfortunately I have obdII scanner n star and no codes come up. I replaced all 4 abs wheel speed sensors. Does anyone know what sensors are tied into this pre safe system. I do not have distronic nor any parking sensors. My car was the base model . Any information would be great.

 

happens when accessory batter is low......

 

I thought pre safe was on cars with distronic plus
