Hello,

I own 2015 S 63 and my car is completely dead so I am assuming it’s the battery. I would like to jump the car or use battery tender but can’t seem to locate the negative charge location under the hood of car. I do see the positive red plus which I can slide open and I do see a negative label on top on the cover but can’t locate the place to charge so does anyone know? Thanks in advance.

Being a 2015 model, you should still be under the factory warranty. Call Mercedes road side assistance, tell them your battery is dead and they will come to you and replace the dead battery free of charge.
