Yeah u can jump from them I'm told but not to it ,it's to do with voltage spike I believe , whatever it is it's not a great idea ,other prob even better cars are fine just not these I'm told ,my battery failed a while ago and it was totally dead ,now normally I'd just buy a new battery and fit it and start car that would b it .
I was told u can't do it that way , so I had to pay for a recovery truck to uplift it , drop off to a mercspecialist ( btw main dealer would b more than what I paid ) he fitted anew Mercedes battery from main dealer(130) fitted it , hooked it up to diagnostic to reset sensors ( because when they go below a certain voltage app they shut down and need on a star ( diag ) machine that was 80 and then vat on it ,it totalled 250 quid for a flat battery!!!( and the recovery charge which was another 60 on top)
