Jump starting using my petrol A-Class (W177)
My main question concerns the terminal connections: Should I open the battery cover and connect the black jumper cable directly to the negative terminal of the battery, or should I use the grounding bolt instead when jump-starting another vehicle? I noticed the negative terminal is covered by a plastic cover.
