What does "Service power steering" warning mean?

A power steering system helps drivers steer vehicles by using hydraulic fluid pressure. The "Service power steering" warning may come on if there is a problem with the power steering system. Drivers may notice increased steering effort, and the vehicle may not respond as well to steering input. It is also possible that the vehicle may veer to one side of the power steering system that is not working properly. If you see this warning, it's important to have the power steering system checked by a mechanic as soon as possible. The power steering system may need to be replaced entirely in some cases.
