When I start my Prius the PS signal came on and steering wheel was stiff
PS sign indicates problem with power steering. most likely is has electrically assisted steering and needs attention. may want to contact the dealer to make sure it is not under a recall before pursuing any further. the Prius cars have had alot of problems recently.

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

There's a known problem with the early Toyota Prius (2001 - 2003), when running the engine for a long period of time without moving or when the car is driven only for short trips (short city driving), the Prius might not start.
You have to change the original battery with a 356 CCA which is bigger because the battery is bigger you also have to change what is holding it into place.

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

could be as simple as you need power steering fluid, which intels you may have a leak, or it could be a bad pump. add fluid, see how long it stays in there, check every day andmore. if it doesnt last a week of driving then you have a leak somewhere. if it does but the problem persits, its the pump

This violent shaking where you can stop it by holding the steering wheel in my experience is due to a BAD rack and pinion. Replace rack and that will solve this problem. Good Luck and thanks for using FIX YA
