Sure, that's what Haynes says for decades but why do you think the quick release is on the positive?
Negative-first is a throwback from the days before quick-release posts where standard, so that people
with spanners would not inadvertadly touch the chassis while trying to undo the positive, causing a short.
It also serves as a quick means of disconnecting the battery incase of an emergency (eg crash).
|
And what happens if you drop something metal like a spanner that touches the head of the engine and the positive pole?

PSA Peugeot / Citroen put at least one quick release terminal on so if the electrical system decides to BBQ itself ( something the 206 isnt know for but other PSA products where ) you can isolate the battery quickly.
Some other PSA products have a quick release on BOTH battery terminals.

Most new vehicles are fitted with it not just Pugs, for the reasons I explained.
And yes some have it on both poles, again for the same reasons.

You risk blowing the battery up & getting showered with acid
Negative terminal should always be disconnected FIRST & reconnected LAST
Not that you need to disconnect anything to jump start a 206 
Positive earth classic car, doubt anyone on here would ever be working on one

You drop a spanner anywhere near the battery poles and you're sorted, negative first OR last.
And who said anything about positive earth? This is a 206 forum last time I checked.

Yours is non plexed, its unlikely to spit the dummy during a jump start attempt ( can happen buts it very rare they even do )
