According to your manual:
The indicator comes on to indicate a malfunction in:
The active traction control system (if equipped);
The AUTO LSD system;
The downhill assist control system (if equipped); or
The hill-start assist control system (if equipped).
Reading about some other Toyota vehicles indicates ABS sensors may have been disturbed. Seems likely based on the items above.
The 05 manual suggests Master Brake Cylinder might be at fault.
Get someone to check the CEL code, and go from there.
