I have a 2013 Mercedes SLK that would not start one day due to a dead battery. I called Mercedes Roadside Rescue, they came out and gave me a jump with a battery charger. Right after that I got an error message on my dashboard with an image showing that my hood was still up. I told the mechanic for Mercedes Roadside Rescue. He open the hood and close it again and it appeared that the light has gone off. As I pulled out my driveway and started to drive again I noticed that the light came back on. Also I noticed that my heat wasn't working at all. It wouldn't even turn on nothing. Is it possible that it could be due to being jumped improperly or maybe a faulty battery charger box?
