LOCK means to lock, and the LOCK button is the child lock for the rear door of a motor vehicle. LOCK is the switch to lock the car. Generally, when the car key is placed in this position, it locks the steering wheel, preventing significant movement. Additional information is as follows: 1. Notes on car child safety locks: Car child safety locks are a feature designed to prevent children from accidentally opening the car door, thereby avoiding potential harm to children. Typically, child locks are located on the two rear doors. When the child lock function is activated, the rear doors cannot be opened from the inside but can be opened from the outside. When the child lock function is deactivated, the doors can be opened from both inside and outside. 2. Two types of child safety locks: There are two common types of child safety lock switches: one is a rotary type, and the other is a toggle type. The rotary child safety lock requires a key (or key-shaped object) to be inserted into the corresponding hole to rotate the switch for locking and unlocking, while the toggle child safety lock is more convenient to use.

The LOCK switch in a car is primarily for the door locks or ignition lock position, and we use it frequently in our daily driving. When I first started learning to drive, I was very curious about this switch, but later I understood that it's the button or rotary position to lock all the car doors. There's a button or label marked LOCK on the door or center console, and pressing it automatically locks all the door locks inside the car, preventing anyone from opening them from the outside, which helps prevent theft and protects items inside the car. Nowadays, many new cars also have an automatic feature—when the speed exceeds 20 km/h, the door locks automatically engage in the LOCK position, saving me the trouble of manual operation. When parking in unfamiliar places, I always make it a habit to engage LOCK for safety. This design is very practical, preventing accidental opening or theft risks. If the child lock is also on the rear doors, using LOCK together provides double safety.

How to Determine if the Balance Shaft is Faulty?

Balance shaft failure manifests as a humming noise from the chassis while driving, with the sound intensifying as the speed increases. The function of the balance shaft is to ensure smoother engine operation and reduce vehicle vibration, thereby enhancing overall driving comfort. Balance shaft technology is a structurally simple yet highly practical engine technology that effectively mitigates overall vehicle vibration and improves driving comfort. Balance shafts can be categorized into single and double balance shafts. The method for aligning the balance shaft is as follows: 1. Align the timing mark on the shaft sprocket with the copper-plated chain link; 2. Place the timing chain on the water pump drive sprocket; 3. Adjust the last chrome-plated chain link so that the timing mark on the exhaust side balance shaft drive sprocket aligns with it.

Which is better, the Avalon or the Passat?

The Volkswagen brand has higher added value, being more advanced after all; compared to the Avalon, it is more steady and restrained in design, making it more suitable for commercial use; it achieves 0-100 km/h acceleration in 7.1 seconds, offering better burst power than the Avalon. Advantages of the Volkswagen Passat: The rear row has a larger lateral width, providing a slightly better feeling for three passengers; the lower configuration price is more affordable, with a lower entry threshold. Disadvantages: Both the exterior and interior designs are relatively conservative; the turbocharged + dual-clutch power combination is not as comfortable as competitors in terms of ride comfort; the Magotan has made us realize that the saying 'German cars are safer' is just a slogan; it falls short of competitors in terms of post-maintenance and quality stability. Advantages of the Toyota Avalon: Safety of the TNGA platform; outstanding ride comfort, dynamic response, and fuel economy of hybrid models; design that combines youthful sportiness with steady elegance; adaptive suspension in conventional models brings higher comfort and better stability; the hybrid model's chassis suspension is softer and more comfortable; better quality stability; noise insulation and quietness are close to the level of the Lexus ES80. Disadvantages: Slightly weaker burst power, with acceleration over 8 seconds; in China, the brand's added value is not as high as competitors; the interior design is simple and straightforward, but this is subjective; it is relatively backward in human-machine interaction, lacking CARPLAY. Apart from the above, the passenger space and fuel consumption of both cars are almost the same as their fuel versions. With a budget of 230,000 yuan, I would choose the Avalon hybrid version because this car is more suitable for family use, saving money and hassle in the long run.

How to Deal with Cockroaches in a Sedan?

Cockroaches prefer to appear in relatively enclosed spaces because it facilitates their egg-laying and reproduction. Sometimes, when you lift the seat cushion, you may find a lot of cockroach droppings. You can use leftover orange or lemon peels—cut them into small pieces, dry them by baking, and then place them in the wardrobe. Cockroaches will avoid areas with this smell. Sprinkling laundry detergent is another method. Cockroaches often appear in places with food or clutter, as they prefer such environments. Trying to step on them is usually ineffective, and even if you succeed, the main issue is the eggs inside their bodies. Sprinkling laundry detergent in areas where cockroaches frequently appear can be effective—if they ingest it, they will die. Afterwards, pour boiling water over them to ensure elimination. Using cockroach gel bait is highly recommended. Simply apply small dots in the corners of the car. Within about a week, all cockroaches in the car will be eradicated, and they won’t reappear. Additionally, avoid storing food or fruits in the car, as this essentially provides a feast for cockroaches. Without a food source, cockroaches will struggle to survive. Banana peels and dish soap water can also be effective. Cockroaches are elusive—they might disappear just as you try to swat them. Leftover banana peels can be useful: cut them into small pieces, soak them in water mixed with dish soap, and place them where cockroaches are often seen. Cockroaches are attracted to sweet foods, and if they consume the banana peels soaked in dish soap, they will die.
