If the sensor line is replaced, decoding is required; if not, simply reset the mileage. Any vehicle requires a break-in period after replacing brake pads. This is because new brake pads need to wear in to achieve optimal contact with the brake discs and deliver maximum braking performance. Therefore, braking force may temporarily decrease after replacement—just be cautious and drive around 1,000 kilometers for proper bedding-in. On-road bedding-in method: Drive the car at around 90 km/h, then lightly apply the brakes—just enough to feel the pads make contact with the discs—and maintain this gentle pressure. Mechanic-assisted sanding: When installing new brake pads, ask the mechanic to sand them. Some mechanics do this automatically to prevent brake noise, as reopening the assembly incurs no additional labor cost. Sanding only affects the edges and doesn't impact the lifespan, since the central portion of the pads provides the primary braking surface.

What is the reason for the ASR-OFF light being on?

This situation may occur due to tire maintenance or removal, or it could be caused by insufficient tire pressure or a punctured tire. If this indicator light comes on, it is necessary to immediately check it. Tires are a crucial component of a car, being the only part that comes into contact with the ground, so it is important to pay attention to your car's tires. More relevant information is as follows: 1. Low tire pressure: This can cause the tire to exhibit wave-like deformation during high-speed driving, increasing the risk of a blowout and accelerating tire aging. 2. High tire pressure: This reduces the contact area between the tire and the ground, leading to decreased grip. 3. If grip is reduced: The car's handling and driving stability will be affected. 4. Tires are rubber products: Rubber products will age over time with prolonged use, so tires need to be replaced regularly. Under normal circumstances, tires installed on a car can last for four years, so it is recommended to replace them every four years. When purchasing new tires, always check the production date, as tires also have a shelf life. Normally, the shelf life of unused tires is three years.

Is It Necessary to Clean the Fuel System at a 4S Shop?

It is necessary to clean the fuel system during car maintenance. Here is a detailed introduction about cleaning the car fuel system: 1. Cleaning interval: It is generally recommended to clean the fuel system every 30,000 to 40,000 kilometers driven. Considering the quality of domestic fuel, the ideal condition is to clean it every 20,000 kilometers. 2. Reasons for cleaning: If the fuel system is not cleaned for a long time, carbon deposits and sediments can clog the needle valves and valve holes of the fuel injectors, affecting the performance of the precision components in the injection system, leading to poor fuel injection, inadequate atomization, or even no injection. This can result in unstable idling, increased fuel consumption, poor acceleration, and difficulty starting the car.

Can you change lanes on a white solid line?

White solid lines can change to center dashed lines, allowing for lane crossing for overtaking or turning. Below is an introduction to traffic lines: 1. Center single solid line (yellow): Vehicles must not cross the line. 2. Center combination solid and dashed line (yellow): Vehicles on the solid side are prohibited from crossing the line for overtaking or left turns. 3. Center double solid line (yellow): Strictly prohibits vehicles from crossing the line for overtaking or driving on the line. 4. Stop line (white solid line): A white solid line perpendicular to the center line. 5. Lane dividing line (white solid line): Separates vehicles traveling in the same direction.

What is the fuel consumption of FAW-Volkswagen Talagon?

FAW-Volkswagen Talagon has a fuel consumption of 7.2-9.7L/100km. The following are several factors that affect fuel consumption: 1. Road conditions: Generally, flat roads consume less fuel than bumpy roads, straight roads consume less fuel than curved roads, and smooth roads consume less fuel than congested roads. 2. Weather: In hot summer weather, air conditioning cooling will consume some fuel. In winter, low temperatures prevent gasoline from reaching the optimal combustion temperature, leading to incomplete combustion and additional fuel consumption. 3. Tire pressure: Low tire pressure will increase fuel consumption. 4. Engine: Dirt and grease on the engine surface can affect engine cooling, leading to increased fuel consumption. 5. Carbon deposits in the transmission: Carbon deposits in the transmission can reduce engine power, which to some extent accompanies increased fuel consumption, as achieving the same power as before the carbon deposits requires increasing throttle opening and corresponding fuel supply.

Is a Power of Attorney Required for Vehicle Inspection in Another Location?

It needs to be processed annually because the power of attorney has an expiration date. Here is relevant information about vehicle inspections: 1. Timeframe: For passenger cars and blue-license-plate minivans, the first six years after new vehicle registration require inspection every two years; after six years, it becomes annual; after ten years, inspections are conducted once a year; after fifteen years, twice a year. For trucks, inspections are required annually after registration, and after ten years, twice a year. 2. Regulations: If a vehicle is found by traffic police on the road without a valid inspection, the owner may face fines or vehicle impoundment. Additionally, in insurance contracts, vehicles that have not undergone timely inspections are considered unqualified, and no claims will be paid in the event of an accident.
