What does PS on a car stand for?

[VanLucia]

PS on a car refers to the Power Steering Lock indicator. After starting the car, the steering wheel lock is engaged, and the light disappears. If the PS light is on, generally, the key cannot be turned when inserted; by gently moving the steering wheel left and right, the light will go off, allowing the key to turn and the car to start normally. The steering wheel lock is a very basic anti-theft feature of a car. Its principle involves using the rotation of the key to control a steel pin via a spring. When the key is removed, any movement of the steering wheel causes the steel pin to pop into a pre-drilled hole, locking the steering wheel in place to prevent it from turning. When the steering wheel is locked, it cannot be turned, the key cannot be rotated, and the car cannot be started, thereby achieving the anti-theft function. PS displayed on the car dashboard: When the car dashboard displays PS, it is an indicator light for the Power Steering system. The PS light turning on during ignition is part of the self-check process and should go off while driving. If the light remains on during driving, it indicates a fault in the Power Steering system, and the car should be taken to a 4S shop for repairs.

I asked this question when I first bought my car. PS in cars usually stands for Power Steering, known as the power steering system in Chinese. It's like an invisible assistant, helping you turn the steering wheel effortlessly, especially in city traffic or when parking. Without it, steering would be extremely heavy, almost enough to tire out your arms. It provides assistance through a hydraulic pump or electric motor, making driving more effortless and comfortable. I remember once driving an old car on a long trip when the PS system leaked and failed—the steering wheel became as heavy as pushing a big rock, which was very unsafe. It was only during repairs that I learned the importance of regularly checking the power steering fluid or electronic components. New cars generally use electric power steering, which is more eco-friendly and efficient. After driving for a while, I remind my friends that if the PS light on the dashboard comes on, don’t ignore it—get it checked as soon as possible, or it could lead to an accident.

As a new driver who just got my license, I was particularly curious about the PS in cars. It actually stands for Power Steering, which is the power steering system. This thing is truly magical - it secretly assists when you turn the wheel, reducing arm fatigue. For example, when reversing in narrow alleys or making low-speed turns, without power steering the wheel would feel almost locked and hard to turn, but with PS it becomes much smoother. It works through hydraulic or electronic means, and feels super practical in daily driving. When I was learning to drive, my instructor specifically taught me to recognize PS failure signals - if the steering suddenly becomes heavy or makes strange noises, you must stop immediately to check, to avoid losing control on the road. After driving for a while, I noticed that modern cars all come standard with this feature, improving both safety and convenience. New drivers would do well to learn these basic concepts.

In the automotive context, PS primarily refers to Power Steering, the power steering system. The core of this system is to reduce the steering burden through auxiliary devices, commonly using hydraulic or electric mechanisms. Advantages include easy control at low speeds and reduced fatigue. If a malfunction occurs, a warning light will appear on the dashboard, and steering will become heavier, requiring professional inspection and repair.
