What does the VIN on a car mean?

Why does the car automatically lock when the door is closed?

The reasons for the car door automatically locking are as follows: 1. Damage to the central control system: It is necessary to replace the sensors on the car door and check if there is an issue with the central control system to perform repairs or replacement. If the car door always locks automatically, it poses a significant safety hazard. After the car is locked, there is a possibility it may automatically unlock again, leading to the loss of items in the vehicle. 2. Controller malfunction: The vehicle's anti-theft locks can be divided into three categories based on technical principles: mechanical anti-theft locks, electronic anti-theft alarms, and networked anti-theft locks. If the car door frequently locks automatically, it is necessary to inspect the vehicle's central lock controller, as the issue may be caused by a malfunctioning controller. You can visit a local after-sales service or repair shop for inspection.

What are the symptoms of an out-of-round tire?

Tire out-of-roundness can cause strong vibrations while driving. Here is some relevant information about out-of-round tires: 1. Hazards: If the front tire is affected, it will impact steering sensitivity, and the steering wheel and seat will experience very noticeable vibrations. Immediate inspection and repair are required. If caused by wheel hub deformation, it may also lead to poor tire airtightness, resulting in air leakage and pressure loss. Tires are the most critical components in a vehicle's driving system, directly related to driving safety. If a tire issue is detected, immediately stop the vehicle safely, replace it with a spare tire, or visit an auto repair shop for servicing. 2. Wheel hub replacement: The most obvious symptom caused by an out-of-round wheel hub is vehicle deviation. If the tire is out-of-round due to wheel hub deformation, the hub must be replaced and should not continue to be used as it poses a safety hazard. Dynamic balancing cannot repair a deformed wheel hub. If the wheel hub exhibits issues such as bending, cracking, or severe corrosion, it should be replaced promptly. Failure to replace a damaged wheel hub may result in the tire slipping off the hub or even lead to loss of vehicle control. However, minor scratches are generally not a significant issue, but deformation requires hub replacement.

What is Coolant?

Coolant, also known as antifreeze, radiator fluid, or radiator protector, primarily functions to ensure the normal and efficient operation of the engine. It circulates within the engine's radiator, providing effects such as freeze protection, boil-over prevention, rust inhibition, and corrosion resistance. Most coolants are colored red or green, and different types of coolant should not be mixed. Below is more information about coolant: 1. Function: Modern engines rely on the combined action of coolant and engine oil to lower the engine's temperature, achieving a dual-cycle cooling effect. During normal operation, coolant will gradually deplete, so it's important to monitor and replenish coolant levels regularly while using the vehicle. 2. Precautions: The coolant level should neither be too high nor too low. The engine compartment's radiator has markings indicating the maximum and minimum coolant level limits.

What maintenance is required for a car at 60,000 kilometers?

The maintenance items for a car after driving 60,000 kilometers include changing the engine oil, replacing the brake fluid, replacing the three filters, changing the transmission fluid, and inspecting the tires. The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life. Here are the maintenance tasks required for a car at 60,000 kilometers: Changing the engine oil. After driving 60,000 kilometers, the car can use higher-viscosity and more protective engine oil, such as 0W-40, to ensure better engine performance. Replacing the brake fluid. Generally, the brake fluid should be replaced around 40,000 kilometers. Replacing the brake fluid ensures the braking system works more effectively. Additionally, during the 60,000-kilometer maintenance, the wear level of the brake pads should be checked. If the wear is severe, the brake pads should also be replaced. Replacing the three filters. These include the air filter, oil filter, and cabin air filter. The three filters are car components that are prone to contamination and wear, so they should be cleaned or replaced during each maintenance session. Changing the transmission fluid. Generally, manual transmission vehicles should have their transmission fluid replaced every 50,000 kilometers, while automatic transmission vehicles can go up to 80,000 kilometers. During major maintenance, the transmission fluid should be inspected. Inspecting the tires. Check whether the tire wear is normal. If the wear is severe, the tires should be replaced promptly. Spark plugs: Ignite the air-fuel mixture to generate power. They also seal the spark plug holes to maintain cylinder pressure. They should be inspected every 40,000 kilometers. Battery: The battery usually needs replacement every 4-5 years, depending on usage habits. If the car's electrical functions (e.g., radio) are frequently used while the engine is off, the battery may wear out faster. Car maintenance generally includes the following inspection or replacement tasks: checking the coolant level; inspecting the brake and clutch fluid levels; verifying the power steering fluid level; checking for oil leaks at pipe connections; examining the battery fluid and windshield washer fluid levels; inspecting the tension and wear of belts (generator, air conditioning, water pump, and power steering pump); ensuring all lights (headlights, daytime running lights, turn signals, brake lights, reverse lights, and fog lights) are functional; checking tire pressure and wear, tightening lug nuts to the specified torque, adjusting tire pressure to the recommended level, and rotating tires if necessary; and verifying that the vehicle’s exhaust emissions meet standards. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as vehicle upkeep. Modern car maintenance mainly covers the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and more.

Why Should Downhill Vehicles Yield to Uphill Vehicles?

Which side should yield when vehicles meet on a slope depends on the actual situation. Article 48 of the "Regulations for the Implementation of the Road Traffic Safety Law" states: On narrow slopes, the vehicle going uphill has the right of way; however, if the downhill vehicle has already reached the middle of the slope while the uphill vehicle has not yet started ascending, the downhill vehicle has the right of way. On roads without central barriers or center lines, the following right-of-way rules apply when encountering oncoming traffic: 1. Obstacle sections: On sections with obstacles, the vehicle without obstacles has the right of way; but if the vehicle with obstacles has already entered the obstacle section while the vehicle without obstacles has not yet entered, the vehicle with obstacles has the right of way. 2. Mountain roads: On narrow mountain roads, the vehicle not next to the mountain has the right of way. 3. Slopes: On narrow slopes, the vehicle going uphill has the right of way; but if the downhill vehicle has already reached the middle of the slope while the uphill vehicle has not yet started ascending, the downhill vehicle has the right of way. 4. Pedestrian crossings: Regarding yielding to pedestrians, when motor vehicles approach a pedestrian crossing, they should slow down; if pedestrians are crossing, the vehicle must stop and yield. When motor vehicles are on roads without traffic signals and encounter pedestrians crossing, they should give way.
