Need Help FAST! (thanks)

[Makavelli]

Hey guys, I'm lookin at buyin an 87 NA Supra. There is an orange light on the dash that indicates something to do with the real wheels--? What does that mean?
Also, it was 105 degrees when I test drove it, and as I returned it to the dealership and parked it, it began to spew orange fluid, and began to steam. The temperture gauge read normal. The engine runs strong and hard, only having 112k miles (not bad for an all origional 87).

Any advice at all would be appreciated.

Thanks!
