So I've got this old 2002 Iveco 75e17-there's a button the dash marked 'km'. When I push it, a light comes on the dash that says 'km' but nothing else seems to happen-anyone know what it is?
I need to know now, I swear that's what it is though. Give it a press when you're doing 40, its been years since I've driven one but I think that I used to use it in some roadworks.
