The rearview mirror heating switch on the Audi A4 is located on the exterior rearview mirror knob on the driver's door. Rotate the knob to the corresponding position to adjust the direction and function of the desired rearview mirror. The left and right rearview mirror icons allow you to adjust the exterior mirrors on the driver or passenger side. Here is some related information about the rearview mirror heating function: 1. Symbol: The rearview mirror heating symbol features a curved upward arrow paired with a rectangular shape. While the switch location may vary across different car models, the symbol is generally similar. 2. Working principle: A heating element (electric heating film) is installed inside the mirrors on both sides. In rainy or snowy weather, when the driver activates the rearview mirror heating function, the heating element quickly warms up to a fixed temperature (usually between 35-60 degrees Celsius) within a few minutes, effectively defogging and defrosting the mirrors.

What is Yokohama Tire?

Yokohama is Yokohama Tire, originally known as Yokohama Tire, from Yokohama Rubber Co., Ltd. in Japan. The main products of Yokohama Tire are radial tires for trucks and buses, various tires for construction vehicles and industrial vehicles, as well as pipes, aluminum alloy wheels, and automotive-related products. Tires are one of the important components of a vehicle, and their functions include: 1. Supporting the entire weight of the vehicle, bearing the load of the car and transmitting forces and moments in other directions; 2. Transmitting traction and braking torque to ensure good adhesion between the wheels and the road surface; 3. Working together with the car suspension to cushion the impact during driving and dampen the resulting vibrations.

What is Hankook Tire?

Hankook is a Korean tire manufacturer that produces radial tires for passenger cars, light trucks (SUVs, RVs, etc.), trucks, buses, and specialized racing vehicles. Its tires can continue to support the vehicle independently even in a zero-pressure state, allowing the car to travel at least 80 kilometers at a speed of 80 kilometers per hour, achieving run-flat capability. Hankook Tire has developed run-flat tire technology, including the HRS system and its unique SMH technology. This technology enhances the sidewall support of the tire, offering three major advantages: strong shock absorption, run-flat capability, and high-temperature resistance, thereby reducing the risk of accidents. Hankook's run-flat tires are widely used in BMW 1 Series, 3 Series, 5 Series, and X5 models.

What is an EGR Valve?

An EGR valve is a mechatronic product installed on diesel engines to control the amount of exhaust gas recirculated back into the intake system. It is typically located on the right side of the intake manifold near the throttle body and is connected to the exhaust manifold via a short metal pipe. The principle of the EGR valve is to regulate the volume of exhaust gas entering the intake manifold, allowing a specific amount to flow back for recirculation. As a crucial component of the exhaust gas recirculation system, the EGR valve redirects engine combustion exhaust back into the intake manifold for re-combustion. This process lowers combustion chamber temperatures, enhances engine efficiency, improves combustion conditions, reduces nitrogen oxide emissions, minimizes knocking, and extends engine lifespan.

What does bare car mean?

Bare car is a specialized term in the automobile manufacturing and sales industry, usually referring to a commodity vehicle that has not been equipped with any non-standard accessories after leaving the factory. Once the dealer adds decorative parts such as insurance bumpers, side skirts, and spoilers to the original factory configuration before sale, it is no longer called a bare car. After purchasing a car, you also need to pay: purchase tax, vehicle inspection fee, license plate fee, vehicle and vessel usage tax, and compulsory traffic accident liability insurance. Additionally, some conventional insurances are basically mandatory: third-party liability insurance, vehicle loss insurance, vehicle theft insurance, and no-deductible special insurance.

What is the cleaning method for a car carburetor?

The cleaning method for a car carburetor is as follows: 1. Remove the air filter and start the engine to reach maximum RPM; 2. Wear clean gloves or use a clean cloth to quickly cover the carburetor intake. You should feel a strong suction on your palm, and the engine RPM will gradually decrease. When the RPM is low enough, release your palm to allow the engine to return to normal operation; 3. Repeat the above two steps several times until the engine operates normally. If carburetor cleaner is available, it can be used to reduce the number of repetitions. A car carburetor is a mechanical device that mixes a precise ratio of gasoline and air under the vacuum created by the engine. As a precision device, it utilizes the kinetic energy of the incoming airflow to atomize gasoline, playing a crucial role in the engine—often referred to as the heart of the engine.

What is the function of a car stabilizer bar?

Car stabilizer bar is designed to reduce the overall vibration of the vehicle, making the engine work more smoothly, reducing noise, and improving ride comfort. When the engine is running, its speed is fast and uneven, and its inertial force generates upward, downward, and lateral movement forces, which cause vibration. The hardness of the stabilizer bar is determined by the material used, the length of the bar body, the diameter of the bar, the length of the bar arms, and the angle formed with the bar body. The longer the length of the bar body, the softer the hardness, while the shorter the length of the bar arms, the harder the bar becomes. Due to the limitation of the vehicle width, the length of the bar body can hardly be changed, but the diameter of the bar and the length of the bar arms can be adjusted more easily.
