When you say it's got smoke coming out of it, from where ? Do you mean from the engine bay, or is it just coming from the exhaust, because IS200s do seem to produce quite a lot of steam.
The Toyota coolant is red, so your coolant lid sounds fine.
Don't know about the liquid that's coming out, is this in the engine bay itself or has it dripped out onto the ground ? If you use your hand above where the liquid is, can you find any pipes or similar that appear to be a bit wet ?
