I was browsing through my user manual yesterday and it makes reference to a cooler box which is situated between the drivers seat and the passenger seat. So I looked at it and it isn't a cooler box at all but just a storage area.
Might be available as cooler box in other market, mine also just storage with 12V plug point. Check manual fine print something like “if your model equipped with this”
