The phrase refers to the act of inspecting, maintaining, and repairing the power-assisted steering system in a vehicle. This system reduces the effort needed to turn the steering wheel, making driving easier, especially at low speeds. For instance, when the steering becomes unusually stiff or noisy, or a warning light illuminates on the dashboard, it may indicate the necessity for attention to this particular system.
Proper upkeep of this system is vital for vehicle safety and handling. A well-maintained system ensures consistent steering performance, contributing to driver control and preventing potential accidents. Historically, these systems have evolved from purely mechanical to hydraulic and, more recently, electric assistance, each requiring specialized maintenance procedures to ensure operational integrity and longevity.
