Are Small Lights the Same as Low Beam Headlights?

Small lights refer to low beam headlights. Large lights refer to high beam headlights. Low beam headlights are designed for close-range illumination, with the design requirements focusing on a wide coverage angle (160 degrees), short illumination distance, and non-adjustable focus. High beam headlights emit parallel light, which is more concentrated and brighter, capable of illuminating distant and high objects, thereby improving visibility and expanding the field of view. When to use low beam headlights: When driving in areas without streetlights at night, during dusk when it's getting dark, or at dawn when light is just appearing, it is mandatory to turn on the low beam headlights; if encountering heavy fog, snow, or heavy rain that limits visibility, low beam headlights must be used even during the day; in some areas where lighting is available but insufficient, low beam headlights should also be activated. Function of low beam headlights: Although low beam headlights have an illumination distance of about 30 meters, they feature a very distinct beam cutoff line. Most car low beam headlights illuminate between 30-40 meters, with the beam cutoff line appearing around 12-18 meters. The area in front of the beam cutoff line is brightly lit, allowing clear object identification, and the ground illuminated by low beam headlights typically shows a visible light area of 2-3 meters in diameter.

How Much Impact Does Replacing the Central Control Screen Have on the Car?

Replacing the central control screen will not affect the vehicle. However, if the central control screen is installed unprofessionally or upside down, it may cause the central control screen to malfunction, or even burn out the electronic components inside the car, posing certain safety hazards. The following is an introduction to the car's central control screen: The car's central control screen, also known as the multi-information display screen or the new car computer display screen, displays part of the data from the car's computer in a screen-displayed manner. Most car computers display data such as average fuel consumption, instantaneous fuel consumption, outdoor temperature, average speed, driving time, single-trip mileage, etc., making it easier for the driver to grasp vehicle information in real time; it also has a real-time updated navigation function, providing an accurate driving route.

What is the shifting speed?

The speed range for first gear is 10-20km/h, second gear corresponds to 20-30km/h, third gear matches 30-40km/h, and fourth gear aligns with 40-50km/h. Below are specific details about Subject 3: Gear-speed mismatch: During Subject 3 driving test, vehicles typically operate in third gear, but the speed must not exceed 40km/h in this gear, otherwise it will be judged as "gear-speed mismatch" with a 10-point deduction. Retake policy: For the Subject 3 road driving skills test, candidates have five examination appointment opportunities in total. After each appointment, they can take one regular test and one retake. If the candidate doesn't attend the retake or fails it again, they must schedule a new examination.

How often should the throttle body of a car be cleaned?

The throttle body should generally be cleaned every 20,000 kilometers. The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. Failure to clean the throttle body for an extended period can lead to errors in the throttle opening angle and allow air containing impurities to enter the engine combustion chamber. Both of these outcomes can cause abnormal engine operation, primarily manifesting as unstable idling, a sudden sensation of throttle closure while driving, and a reduction in power. In severe cases, it may even result in difficulty starting the engine and increased fuel consumption. Frequency of throttle body cleaning: How quickly the throttle body gets dirty depends on various factors, including the quality of the air filter, the brand and quality of the engine oil used, driving conditions, air temperature, engine operating temperature, and driving habits. Points to note for throttle body cleaning and prevention: The primary cause of throttle body deposits comes from engine oil vapors, followed by airborne particles and moisture. This means that when using a qualified air filter and removing the crankcase ventilation tube, the throttle body will get dirty at a much slower rate. The crankcase houses the crankshaft and is connected to the oil pan at the bottom. The operating temperature in this area ranges between 100°C and 180°C.

How often should the brake pads of Venucia D60 be replaced?

It depends on the mileage of the car. Generally, they should be replaced every 50,000 kilometers, while some drivers can go up to 100,000 kilometers before replacement. In fact, under normal driving conditions, the service life of the front brake pads is 30,000 kilometers, and that of the rear brake pads is 60,000 kilometers. Check wear for replacement: However, the replacement of brake pads also depends on wear. Brake pads come with grooves. When the wear reaches the same level as the grooves, meaning the grooves disappear, the brake pads need to be replaced. Check warning light for replacement: Check the warning light. Some car models have brake pads with sensor wires. When the brake pads wear to a certain extent, a warning light will appear on the dashboard, indicating that immediate replacement is required. If new brake pads are not replaced, the warning light will remain on. However, this type of brake warning is usually only available in high-end cars. Listen for sounds for measurement: Listening for sounds is the most reliable method for checking, but some phenomena can also indicate the degree of brake pad wear. When you hear a squeaking metal friction sound while lightly applying the brakes, it may indicate that the brake pads have exceeded their usage limit, so it is essential to check them as soon as possible.

What does the red exclamation mark in a Volkswagen mean?

Red exclamation mark (specifically a circle with an exclamation mark inside), this represents a warning for the braking system, mainly indicating a braking system malfunction or low brake fluid level. Solution: Immediate inspection and repair of the braking system is required to avoid accidents. Apart from the red exclamation mark indicating braking system issues, other exclamation marks in a car are yellow, representing general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Main issues include parking sensor faults, fuel cut-off system intervention or failure, external light faults, engine oil pressure sensor faults, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a transmission fault or transmission lubricant level below the normal range. Transmission oil should be replaced promptly. Abnormal Tire Pressure: A horizontal line under a bracket with an exclamation mark in the middle. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating a fault in the car's lights. Solution: Visit a 4S shop for inspection and repair as soon as possible. Alternatively, you can conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting, to identify the problem.
