Precautions for replacing brake pads: After installing new brake pads, the surface of the brake pads is smooth, while the contact surface on the brake disc is uneven. At this time, a situation known as "ineffective braking" may occur. Therefore, it is necessary to break in new brake pads after replacement. Here are the relevant instructions: 1. Find a place with good road conditions and few vehicles to start the break-in process. Accelerate to 60 km/h, gently apply the brakes, and use moderate braking force to reduce the speed to about 10 km/h; 2. Release the brakes and drive a few kilometers to allow the brake pads and discs to cool slightly before repeating the above steps at least 10 times; 3. After the break-in, the brake pads still require several hundred kilometers of driving to achieve optimal performance with the brake discs. During this period, drive carefully to prevent accidents.

I always pay close attention to the safety details when changing brake pads, as it directly relates to driving safety. First, you must park on level ground, engage the parking brake firmly, and use wheel chocks to secure the opposite wheel to prevent rolling. The jack must be positioned correctly, and once the car is lifted, immediately place jack stands for support—otherwise, an accidental drop can be very dangerous. Wear gloves to protect your hands and avoid contact with brake dust—that dust is harmful to the respiratory system. Before installing new pads, clean the brake rotor to ensure there’s no oil or rust; when installing, slowly press the caliper piston back, avoiding excessive force to prevent damaging components. After replacement, I gently press the brake pedal a few times while stationary to allow the rotor and pads to bed in; then, conduct a low-speed test to check for unusual noises or a soft brake feel. Never change pads on a slope or work alone—it’s best to have someone assist and double-check. Following these steps thoroughly can significantly reduce the risk of accidents.

What are the differences between small cars and large cars?

Large cars and small cars differ in the following aspects: 1. Large cars: Large cars refer to vehicles with a total mass of 4.5 tons (inclusive), carrying 20 or more people (excluding the driver), or with a vehicle length of 6 meters (inclusive) or more. Examples include regular buses, medium and above trucks, and large special-purpose vehicles. Large cars use license plates with smaller front and larger rear dimensions, featuring yellow background with black characters. 2. Small cars: Small cars refer to vehicles with a total mass of less than 4.5 tons (inclusive), carrying fewer than 9 people (excluding the driver), or with a vehicle length of less than 6 meters (exclusive). Examples include sedans, jeeps, mini cars, light passenger vehicles, light trucks, and small special-purpose vehicles. Small cars use license plates with uniform front and rear dimensions, featuring blue background with white characters.

Does a new car need maintenance at 3,000 kilometers?

For a new car, maintenance is required either 3 months from the date of purchase or at 5,000 kilometers, whichever comes first. Once either condition is met, the car should be taken to a 4S shop for maintenance. The first maintenance is free within the specified period, but any maintenance beyond the first one will require payment. If maintenance is not performed as required, the 4S shop may consider it as voluntarily waiving the warranty rights, which is not cost-effective because the nature of the vehicle warranty is similar to buying insurance for the vehicle. Below is an introduction to car maintenance: 1. Introduction to car maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. 2. Scope of car maintenance: Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 3. Purpose of car maintenance: The purpose of car maintenance is to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent faults, slow down the deterioration process, and extend the service life.

How to lock the fuel tank cap of a Volkswagen car?

To close the fuel tank cap, simply twist it to the right until you hear a clicking sound. Below are detailed instructions about the fuel tank cap: 1. The fuel tank cap refers to the box on the car used for storing gasoline. It is square in shape, made of stainless steel, and has excellent sealing. There is only a small circular opening, about the size of a bottle cap, for easy storage. It is usually located at the rear of the car. 2. If the fuel tank cap cannot be opened, you can start from the trunk. First, remove the trunk lining that covers the fuel tank. The lining is usually secured by some plastic clips and can be easily pried off with a screwdriver. After removing the lining, you can see the locking mechanism of the fuel tank cap and the cable used for remote operation. Simply pull the cable to open the fuel tank cap.

Are New Energy Vehicles Exempt from Vehicle and Vessel Tax?

For eligible new energy vehicles, there is no need to pay vehicle and vessel tax. According to Article 2 of the "Notice on Preferential Policies for Energy-Saving and New Energy Vehicles and Vessels Regarding Vehicle and Vessel Tax": New energy vehicles and vessels are exempt from vehicle and vessel tax. New energy vehicles exempt from vehicle and vessel tax include pure electric commercial vehicles, plug-in (including range-extended) hybrid vehicles, and fuel cell commercial vehicles. Pure electric passenger vehicles and fuel cell passenger vehicles are not subject to vehicle and vessel tax and are exempt from it. Below are the benefits of new energy vehicles: 1. Fuel energy savings: New energy vehicles generally use natural gas, petroleum gas, hydrogen, or electricity as power sources, saving fuel energy. 2. Reduced exhaust emissions: New energy vehicles produce no exhaust emissions, effectively protecting the environment. Electric vehicles do not emit tail gases and are pollution-free. Hydrogen-powered vehicles emit water as exhaust, which causes no environmental pollution. Since they are essentially zero-emission, they are also exempt from traffic restrictions based on license plate numbers. 3. High efficiency: New energy vehicles generally adopt new technologies and structures, making them more efficient.

Do You Need to Keep Pressing the Accelerator When Driving at a Constant Speed?

When driving, you still need to continue pressing the accelerator after reaching a steady speed; otherwise, the speed will gradually decrease until the vehicle stops. Below is relevant information about pressing the accelerator in a car: Proper Techniques for Pressing the Accelerator: The engine's accelerator is typically controlled by a pedal, also known as the throttle pedal, which regulates the fuel supply to the vehicle's engine. To operate the accelerator pedal, place the heel of your right foot on the floor of the driver's compartment as a pivot point, then gently press the accelerator pedal with the ball of your foot, using ankle movements to press down or release. When pressing or releasing the accelerator pedal, apply force gently, ensuring a smooth and gradual motion. Precautions When Pressing the Accelerator: When driving uphill, avoid pressing the accelerator pedal all the way down. When using a low gear, it is generally advisable to press the accelerator halfway. Similarly, avoid pressing the accelerator pedal fully when climbing a slope. If the engine does not respond with increased speed after pressing the accelerator three-quarters of the way while driving, shift to a lower gear and then press the accelerator to accelerate.

What are the effects of larger tire sizes?

Tire sizes that are too large will result in shorter mileage, failure to pass annual inspections, increased fuel consumption, and may lead to phenomena such as 'tire wear' or 'pulling to one side,' as well as reduced tire lifespan. Specific effects of larger tire sizes: Original tires are more in line with fuel consumption standards. Larger tires mean increased weight, leading to higher fuel consumption during driving. Mileage becomes shorter because as the tire and rim size increase, the tire's diameter and radius lengthen, increasing the circumference. This results in a reduced rotation speed and noticeable changes in the distance covered per rotation. Failure to pass annual inspections is due to Article 16, Section 1 of the 'Road Traffic Safety Law of the People's Republic of China,' which states that no unit or individual may assemble motor vehicles or alter the registered structure, construction, or characteristics of motor vehicles without authorization. Precautions for replacing car tires: When selecting tires, the specifications must match the previous tires and be identical to the other tire on the same axle, including speed rating, load index, tread pattern, brand, size, etc., to ensure safe driving. The valve stem should also be replaced because, after changing tires, the aging cycles of the new tire and valve stem differ. During the new tire's lifespan, the valve stem may develop issues that are not easily noticeable. Therefore, it is best to replace the valve stem when changing tires. Installation direction and inflation: If using original equipment tires, follow the manufacturer's installation requirements. For non-original tires, the side with the production date usually faces outward. For directional tires, align the arrow on the wheel with the car's forward direction. When inflating, fill to the maximum pressure allowed by the tire, then reduce to the manufacturer's specified standard pressure.
