help please..

[Sollicitudin]

greetings, i have recently bought a lil 1.2 punto active, its a cracking lil car, but does have a few niggles.
the engine management light keeps coming on, i have worked out the reset, thanks to a post in stilo section, but now the window (?) light is on.
also when the lights are on there is another light on, but i dont know what it means, its a small yellow light with an exclamation mark in the centre of it.
any help on the reasons for these lights, and how to reset / remedy will be greatly appreciated
