What to Do If Beginners Can't Tell Whether the Steering Wheel Is Straight?

What aspects should be maintained after a new car has traveled 40,000 kilometers?

Here are the aspects that need to be maintained after a new car has traveled 40,000 kilometers: 1. Replace the engine oil, oil filter, and air filter. 2. Replace the coolant, brake fluid, and fuel filter. 3. Automatic transmission cars also require transmission fluid replacement: During the break-in period, metal shavings may accumulate in the fluid. Timely replacement can improve transmission performance. 4. Rear-wheel-drive cars also need differential oil replacement. 5. Replace the power steering fluid to prevent the steering wheel from becoming too heavy. 6. Replace the spark plugs: Spark plugs directly affect whether the engine can start. 7. Replace the brake pads: After 40,000 kilometers, brake pads typically show significant wear. 8. Replace the tires: Prolonged driving may cause certain damage to the tires.

Is coasting in neutral gear harmful to an automatic transmission car?

Coasting in neutral gear can damage the transmission of an automatic transmission car. Additional information: 1. When an automatic transmission car is shifted into neutral gear while driving, the oil pump in the automatic transmission cannot supply oil normally for lubrication, which will cause the temperature of internal components to rise and lead to complete damage. 2. Coasting in neutral gear refers to the operation method where the driver places the gear lever in the neutral position while the vehicle is moving, separating the clutch between the engine and the drive wheels, and using the vehicle's inertia to move. Coasting in neutral must be performed under the condition of ensuring safety and normal vehicle technical condition. It is not allowed to coast with the engine off, especially when going down steep or long slopes, coasting with the engine off or in neutral gear is prohibited.

What does EV mean on a car?

EV button actually refers to the pure electric driving mode. Here is relevant information: Introduction: A mode driven by electric motor, which is not available in conventional power vehicles (conventional power refers to gasoline or diesel vehicles). EV mode is usually equipped in pure electric vehicles or hybrid vehicles. EV button: When using hybrid models, the EV button can serve as an auxiliary mode rather than the main driving mode. When using EV mode, the fuel engine in hybrid models will not start, thus unable to charge the battery, resulting in lower range in EV mode.

Can All Cars Use Full Synthetic Oil?

Not all vehicles are suitable for full synthetic oil. Below is relevant information about synthetic oil: 1. To obtain higher-performance motor oil, humans have chemically synthesized various oils, known as chemically synthesized oil or simply synthetic oil. 2. Synthetic oil is an artificially manufactured lubricant. During production, various natural substances undergo chemical decomposition and are then synthesized with other materials before finally producing synthetic oil. 3. Synthetic oil manufacturers produce different types of synthetic oils based on user requirements. Depending on the intended use, the composition of synthetic oil can be adjusted. 4. The advantages of synthetic oil include superior quality, which manifests in noticeable improvements in the following aspects: smoother cold starts, particularly evident in northeastern regions; better fuel efficiency; extended oil change intervals, approximately 1.5 times longer or more compared to conventional lubricants; prolonged engine lifespan with reduced maintenance needs; and cleaner engine cylinders due to synthetic oil's excellent detergency. 5. In industries such as automobiles and motorcycles, racing cars were the first to adopt synthetic oil, as they predominantly use synthetic oil instead of mineral oil. While synthetic oil performs exceptionally well, it can also be used in regular vehicles. Its main drawbacks are higher manufacturing costs and elevated prices compared to conventional oil. With increasingly stringent vehicle emission requirements, synthetic oil must also take measures to avoid environmental pollution.

What does the A above and S1 below on car glass mean?

The meaning of A above and S1 below on car glass is: Meaning: It indicates the light transmittance of the glass. Representation: AS1 represents that the light transmittance of the glass is not less than 70%, applied to the front windshield; AS2 is below this standard, applied to door glass, rear windows, and other positions. Information about glass light transmittance is as follows: Glass light transmittance: The percentage of luminous flux passing through transparent or semi-transparent objects to its incident luminous flux. Properties: When light is incident on the glass, it exhibits three properties: reflection, absorption, and transmission. The property of light passing through the glass is called "transmission," represented by light transmittance. Light blocked by the glass and reflected at a certain angle is called "reflection," represented by reflectance. After light passes through the glass, part of the light energy is lost, which is called "absorption," represented by absorptance. Glass reflectance + absorptance + transmittance = 100%.

How Many Kilometers Should a Vehicle Be Driven Before Scrapping?

Non-commercial vehicles and commercial vehicles have different scrapping periods, as detailed below: Scrapping Regulations for Non-commercial Vehicles: For household 5-seat sedans and 7-seat SUVs, as well as non-commercial small and mini vehicles, there is no usage period limit. When the normal mileage reaches 600,000 kilometers, the state will guide the scrapping. In addition to the above vehicles, small and mini non-commercial passenger vehicles, large non-commercial sedans, and wheeled special-purpose machinery vehicles also have no usage period limit. Common Scrapping Regulations for Commercial Vehicles: Small and mini taxi passenger vehicles have a scrapping period of 8 years, medium-sized taxi passenger vehicles have a scrapping period of 10 years, and large taxi passenger vehicles have a scrapping period of 12 years. Public bus passenger vehicles have a scrapping period of 13 years, other small and mini commercial passenger vehicles have a scrapping period of 10 years, and large and medium-sized commercial passenger vehicles have a scrapping period of 15 years. Mini commercial trucks have a scrapping period of 8 years, light and large commercial trucks have a scrapping period of 10 years. The vehicle scrapping process is as follows: The vehicle owner applying for scrapping and renewal must fill out an "Application Form for Vehicle Modification, Transfer, Alteration, Suspension, or Scrapping" and affix the owner's seal. The registration office will accept the application and issue a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping period. For vehicles that have not reached the scrapping period, the vehicle inspection office will determine if they meet the scrapping standards and issue a "Vehicle Scrapping Notice" if applicable. The vehicle owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The vehicle owner must submit the "Modification Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the vehicle inspection office for verification and signature. The license plates will be reclaimed, and the application will be submitted for approval according to regulations to complete the scrapping registration. Special Notes: According to Article 30 of the "Regulations on the Registration of Motor Vehicles", if a vehicle cannot be driven back to the registration location due to damage, the owner can submit the scrapped vehicle to a local recycling company. If a commercial vehicle is converted to a non-commercial vehicle, it must be scrapped according to the original commercial vehicle's scrapping period. According to Article 43 of the "Regulations on the Registration of Motor Vehicles", after completing the transfer or cancellation of a motor vehicle, the original owner can apply to use the original license plate number when registering a new vehicle. The application must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation; (2) The owner must have owned the original vehicle for more than three years.
