Most cases of the central control screen going black when turning on the headlights are caused by circuit board issues. Below are the reasons for car navigation display screen blackouts: 1. Vehicle power voltage issues: Check the stability of the car's power voltage. 2. Car navigation cables: If the voltage is stable, check whether there are any issues with the cables on the back of the device. Try replacing the connections to troubleshoot. If during contact, the display cables should be checked. If there's a problem, test with a new device. 3. Display and sound: If there's no image but sound is present, it indicates a loose power plug for the navigation display. If there's neither sound nor image, it's likely a DVD malfunction.

What is the 0-100 km/h acceleration time of the Leiling Hybrid?

According to official data, the Toyota Leiling Hybrid 1.2T has a 0-100 km/h acceleration time of 10.37 seconds. Factors affecting a vehicle's 0-100 km/h acceleration time are as follows: Torque: Torque, in layman's terms, represents how much force is available. The greater the torque, the more force is available to propel the vehicle, resulting in naturally faster acceleration. The Audi R8 has a maximum torque of 570 Nm and a 0-100 km/h acceleration time of 3.1 seconds. The Leiling Hybrid has a torque of 185 Nm and a 0-100 km/h acceleration time of 10.37 seconds. Transmission efficiency: The transmission is the medium for transferring power and inevitably involves power loss. The higher the transmission efficiency, the better the acceleration performance. Generally, the ranking of transmission efficiency is as follows: manual transmission > dry dual-clutch transmission > wet dual-clutch transmission > AT transmission > CVT transmission. The Leiling Hybrid is equipped with a CVT transmission. Power-to-weight ratio: The relationship between horsepower and vehicle weight is called the power-to-weight ratio (unit is Hp/T). The greater the power-to-weight ratio, the faster the acceleration. The Audi R8 has a power-to-weight ratio of 373 Hp/T and a 0-100 km/h acceleration time of 3.1 seconds. The Leiling Hybrid has a power-to-weight ratio of 92 Hp/T and a 0-100 km/h acceleration time of 10.37 seconds.

Will factory car paint crack naturally?

Factory car paint will not crack naturally. However, if corrosive substances adhere to the car and are not removed for a long time, it may cause the paint to crack. Here is some extended information about car maintenance: Regular inspection: It is necessary to regularly check the surface of the car paint. If cracks or scratches are found, they should be treated promptly to prevent further damage from wind and sun exposure in the future. For minor scratches or chips, the general treatment method is to sand the surface with water sandpaper, then apply a professional touch-up pen or use the auxiliary paint provided by the car manufacturer. Avoid using car covers for heat protection: Using car covers can cause friction between the paint surface and the inside of the cover, especially in breezy conditions, which may inadvertently wear down the paint surface.
