What is the function of the illuminated mirror light?

The illuminated mirror light indicates the side assist and lane change assist function, also known as blind spot detection. The working principle involves installing several detection radars on the side of the car. If another vehicle accelerates and approaches from the left or right rear, the radar detects this information and alerts the driver by illuminating the mirror. This enhances convenience and safety while driving. In such situations, the driver should avoid changing lanes and maintain the current lane to prevent accidents and vehicle damage. The vehicle's lane change assist function can detect objects up to 50 meters behind the driver. When the speed reaches 60 km/h and there is a need for a lane change, the system will automatically activate. The lane change assist function is particularly useful in low-visibility conditions such as fog, heavy rain, snow, or dimly lit environments at night. It helps mitigate safety risks caused by the driver's inability to clearly see vehicles behind through the mirrors. Vehicle mirrors come with multiple functions, including blind spot monitoring and warning systems, turn signal systems, mirror heating systems, power folding, power adjustment, and automatic tilt-down when reversing. Mirrors are crucial and indispensable components of a vehicle. If damaged, they should be promptly repaired or replaced. As a critical safety component, the mirror's surface, shape, and operation are carefully designed. Therefore, the quality and installation of mirrors must comply with industry standards and specifications and cannot be altered arbitrarily.

I've been driving for over a decade, and when the mirror light comes on, it usually means the blind spot monitoring system is active. While driving, if there's a vehicle or obstacle in your blind spot that can't be seen in the mirror, the light will illuminate to remind you not to change lanes hastily, preventing potential collisions. This feature is quite common in new cars, especially on highways or in congested urban areas, significantly enhancing safety. However, it's not foolproof—you still need to visually confirm. In some high-end models, the light may flash, indicating closer proximity to danger. During regular maintenance, it's good to check if the sensors are clean to avoid false alerts. Overall, this feature adds peace of mind to driving, reducing unnecessary accidents.

What is the difference between MT and CVT?

MT and CVT both refer to types of automotive transmissions, with the difference being that MT stands for manual transmission, while CVT is an automatic transmission. Below are the relevant introductions about MT and CVT: MT: MT requires manually shifting the gear lever (commonly known as the gear stick) to change the gear engagement position inside the transmission, altering the gear ratio to shift the car's speed. Most manual transmissions in passenger cars are four or five-speed gear transmissions, typically equipped with synchronizers for easier shifting and reduced noise. When operating a manual transmission, the clutch must be depressed to move the gear lever. CVT: The gear ratio in a CVT is not a series of discrete points but a continuous range of values, for example, it can vary from 3.455 to 0.85. The structure of a CVT is simpler than that of a traditional transmission, with a smaller size. It does not have the numerous gear pairs of a manual transmission nor the complex planetary gear sets of an automatic transmission. Instead, it primarily relies on the primary and secondary pulleys and a metal belt to achieve stepless variation of the gear ratio.

What is the standard tire pressure for cars?

The standard tire pressure for cars is between 2.4 and 2.5 bar. Tire pressure significantly affects vehicle performance and power. The impacts of overinflation are: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Steering wheel vibration and deviation, reducing driving comfort; 3. Accelerated wear on the central tread pattern, shortening tire lifespan; 4. Increased body vibration, affecting the longevity of other components. The effects of underinflation include: 1. Increased friction coefficient with the road surface; 2. Heavier steering wheel feel and tendency to deviate; 3. Increased movement of tire components, causing abnormal heat generation due to excessive rolling.

What Does the Three-Year or 100,000-Kilometer Vehicle Warranty Cover?

The three-year or 100,000-kilometer vehicle warranty primarily covers the core components of the vehicle, which include the engine, chassis, transmission, and drivetrain. The vehicle warranty means that the manufacturer will replace faulty parts free of charge if they are confirmed to be defective due to quality issues rather than human damage, provided the replacement occurs within the warranty period or the specified mileage limit. The warranty does not apply under the following circumstances: 1. Failure to follow the manufacturer's requirements for regular maintenance at designated 4S shops or authorized service stations; 2. Unauthorized modifications to the vehicle or changes to its intended use; 3. Damage caused by improper use or traffic accidents.
