I am assuming the battery will be dead or extremely weak. Last time I had
to jump this ML it caused a problem with the igition switch. Some how the
key stopped being read when placed in ignition to start. < I remember them
saying a red light should flash near the radio if the key is reading. >

As I recall it would crank but not start. Anyway ended up at the dealer where
they took about 5 days to figure out the problem. Where I have the truck now there are no MB dealers only BMW. ( As for as anyone who would have a clue on the ML or MBZ I would have great doubts... maybe BMW but ??? )

So to avoid the same problem occuring please advise.

1> should I even attempt to jump the vehicle, or am I setting myself up for
what happened last time. < is that common is jump starting problem ? >

2> If a jump start is not a problem, is there a special way to do it. ?

3> Should I just take the battery out and have it charged before even trying
to start it to avoid any possible issues. << Seems obvious this might be
the way to go. ... >>

I do have radio code for the vehicle.

A note, I have a CLK that needed a jump a few months back. MBZ service came and the tech used the brief case type jumper and I have had no issue
like the ML issue i had.

Others thoughts or experience with this is greatly appreciated.
