Very good tutorial, thank you, for my 308 from 2009, for step 4, once the + (positive) of the battery is disconnected, there is no risk. The - (minus) will be disconnected at step 6 once the fixing with the 10 bolt is removed, before not possible.
If you need to recharge the battery, to access the - (minus), once the hood is open, on the chassis between the 2 headlights, there are 2 metal pins in the shape of pulleys, one on the right side and the other on the left side. Also useful for measuring the battery voltage.

Very good and many thanks, but is it possible to be more specific in step 4 because where is the - terminal?
and above all how to access it to unplug it and then plug it back in?
Which brings me to another question:
If you want to start with jumper cables, OK to connect the cable to the + terminal, BUT how do you do it for the one to the - terminal?
Thank you for your help.

Hello, I had the problem this morning. In fact, it is enough to connect the minus cable to an unpainted metal part (the paint acts as an insulator).
