The 'lock' displayed on the car dashboard refers to the ignition switch, which is the switch for the car's ignition system (usually operated with a key). It can freely open or close the main circuit of the ignition coil. The car ignition switch has four positions: START, ON, ACC, and LOCK. LOCK is for locking the steering wheel; ACC allows some electrical components like the radio to be turned on; ON connects all electrical components in the car, and this is the position during normal driving; START is the position for ignition. The term 'LOCK' refers to the lock position, which is also where the key is inserted and removed. Placing the switch in this position locks the steering wheel, preventing significant movement.

Last night when I was driving my friend's car, the dashboard suddenly displayed 'LOCK,' which gave me a scare. It turned out the steering wheel lock was triggered because it automatically locks in certain positions after parking to prevent theft. The solution is simple: sit in the driver's seat, gently turn the steering wheel while turning the key to start the ignition, and you'll hear a click as it unlocks. Avoid using excessive force, as it could damage the steering system. Similarly, if an automatic transmission car displays 'LOCK' when shifting gears, it might be the transmission protection kicking in, and you should check if the gear is in 'P' (Park). Safety first—don't panic if this happens, as most cars are designed this way to protect the owner.

As an automotive system enthusiast, I'll analyze the meaning of the LOCK display. It typically indicates the activation of a locking mechanism, most commonly the steering column lock or gear shift lock. This is controlled by the vehicle's ECU as part of the anti-theft system: after turning off the engine, when the steering wheel is turned to position, the mechanical lock engages; in automatic transmissions, the LOCK light may also illuminate if the transmission sensor detects an anomaly. Solutions include restarting the engine or checking the key position. Avoid attempting to forcibly move the vehicle to prevent triggering more complex issues; regular maintenance of the electronic systems can prevent such faults, which is simple and effective.

If the dashboard displays LOCK, it indicates a system lock, most commonly the steering wheel being locked. You must unlock it before starting the car; ignoring it and driving forcefully is dangerous and may lead to steering failure or accidents. Don't panic: sit in the driver's seat and gently turn the key while simultaneously turning the steering wheel to unlock it. For automatic transmissions, LOCK may indicate gear protection, so ensure the car is in P (Park) mode. The essence of safe driving is paying attention to these small warnings—developing the habit can help avoid risks.
