What does the AutoLSD light mean?

AutoLSD refers to the activation of the Automatic Limited-Slip Differential system. Here is some relevant information about the Limited-Slip Differential: 1. Introduction to Limited-Slip Differential: The English abbreviation for Limited-Slip Differential is LSD, which stands for Limited-Slip-Differential. 2. Function of Limited-Slip Differential: During operation, it ensures that both left and right wheels rotate together while keeping the speed difference between them within a certain range to maintain normal vehicle movement. The Limited-Slip Differential is located between the wheels or axles, compensating for the ordinary differential's tendency to spin when a wheel is off the ground. The differential lock is the locking mechanism of the differential, used to lock the inter-wheel differential (between the left and right half-shafts) or the inter-axle differential (between the front and rear drive axles), addressing situations where one or more wheels lose traction and cannot free themselves.

The Meaning of Pure Electric Vehicles?

Pure electric vehicles refer to vehicles that use on-board power as their energy source, drive the wheels with electric motors, and meet all the requirements of road traffic and safety regulations. The following is a related introduction about pure electric vehicles: 1. Reasons for the small market of pure electric vehicles: Despite a long history of 186 years, they have been limited to certain specific applications, resulting in a small market. The main reason is that various types of batteries generally suffer from serious drawbacks such as high cost, short lifespan, large size and weight, and long charging times. 2. The role of pure electric vehicles: Due to their relatively smaller environmental impact compared to traditional vehicles, their prospects are widely optimistic, but current technology is still not mature.

What is the Scrap Period for Trucks?

Low-speed trucks equipped with single-cylinder engines have a mandatory scrap period of 9 years, while low-speed trucks equipped with multi-cylinder engines and mini trucks have a mandatory scrap period of 12 years. Here is some relevant information about the scrap period: 1. Definition of Scrap Period: The vehicle scrap period refers to a safety inspection system based on the number of seats and the duration of use for vehicles. According to regulations, small and micro non-operational passenger vehicles, large non-operational cars, and wheeled special-purpose machinery vehicles have no usage time limit. 2. New Standards for Scrapping: According to regulations, registered motor vehicles must be mandatorily scrapped under the following circumstances: reaching the specified usage period; or failing to meet the national safety technical standards for in-use vehicles even after repairs and adjustments.

What are the pros and cons of car mirror rain visors?

Pros and cons of installing rain visors on rearview mirrors: 1. Advantages: Most rearview mirror rain visors are attached to the mirror cover using double-sided tape, serving to block rainwater. They are very suitable and effective during light to moderate rain. 2. Disadvantages: In heavy rain, the effectiveness of the rain visors diminishes, and the rearview mirror can still get wet. This improvement is more noticeable when it starts raining while driving. If it rains while the car is parked, stationary rain visors can accumulate many raindrops over time as rain continuously falls on them. It's necessary to wipe the rainwater off before driving.

What is the correct way to use the car's sport mode?

When the vehicle is in operation, shift the gear from D to S to enter sport mode. The RPM will exceed 3000 and will not automatically upshift. Quickly press the '+' button to shift up to S2, and the RPM will drop to 1300-1500. When you press the accelerator and the speed reaches 30 km/h, the RPM will exceed 2000 again. Press '+' to shift to S3, and the RPM will drop back to 1300-1500. The S mode is used in the following situations: 1. Overtaking: The downside of S mode is significantly higher fuel consumption due to prolonged low-gear operation. D mode is more fuel-efficient than S mode but offers less direct power. Many drivers use S mode for overtaking and switch back to D mode afterward. 2. Carbon deposit removal: Engaging S mode increases engine load and raises internal temperatures in a short time, which helps remove carbon deposits from the engine. 3. Uphill driving: Many drivers use D mode for climbing, but S mode provides stronger power, making uphill driving easier. 4. Downhill driving: Some may wonder why S mode is useful downhill. In S mode, the transmission stays in a lower gear, reducing traction output when not accelerating, which eases brake pressure. 5. Starting with insufficient power: Older cars with weaker performance can use S mode for starting. Sometimes, when the AC is set too high in summer and affects the car's power, S mode can help by increasing engine RPM and reducing the power drain from the AC.
