smoke from passenger vent

[ultimate1]

I went out for a drive this morning and as I started to hear a rattling sound and someone told me that smoke was coming out of the passenger vent. The good thing is taht this started when I was about a half a mile from the house and when I got home I smelled antifreeze and smoke was coming out of the passenger vent. I looked under the car and I saw something had leaked out and that it was causing the smoke. The other thing is that the ABS light, Traction Control Warning light ( The one with the ! symbol on it) and I lost all power steering as I turned into my drive way.

I am waiting for the car to cool down and I welcome any thoughts on what this could be from.

Thanks in advance!
