I had the same problem. I unplugged the relays from the fuse/relay box under the bonnet. (Top left side) and replaced them. The problem disappeared. (2001 Prius 109,000 miles)

your owners manual should show all of the symbols and what they mean.I tried to get one to look at it but no luck...they should be in the manual though

I don't know about hybrids, but on most vechiles, you check power steering fluid with engine running.

Hi. When you have that particular light on, you need to get the power steering motor checked. This is not something that a non-Toyota service shop can check out. You need to take it to a Toyota dealer. They can check the steering motor system, and diagnose exactly what the issue is. Unfortunatly, there is no other way you can check it, as there is not "pump" on the stweering, it is actually a small motor that runs the steering.
