Can vehicle urea be used after being stored for two years?

Vehicle urea that has been stored for two years cannot be used. Additional information: Vehicle urea is a pure but relatively unstable chemical compound. The following four points should be noted during storage: 1. Storage temperature requirements: Vehicle urea requires a storage temperature of approximately -5 to 25°C to avoid exposure to light and high temperatures. In summer, the urea solution should be cooled. If a strong ammonia odor is detected when opening the container lid, usage should be discontinued. Urea will crystallize at low temperatures, expanding in volume by about 7%, so do not fill the urea solution to full capacity—maintain it at around 90% of the container's volume. 2. Vehicle urea has a shelf life: It is recommended to use factory products within six months. For products stored over a year, strong recommendation is to avoid usage. 3. Special storage containers and filling equipment are required: Urea reacts chemically with metals such as copper, iron, and aluminum. Prolonged exposure to these metals can degrade the urea quality, subsequently affecting the SCR system's performance. Special filling equipment must be used when refilling the vehicle with urea.

Does the light indicate the recirculation mode?

When the light is on, it indicates the recirculation mode; when the light is off, it indicates the fresh air mode. Here is an introduction to the air conditioning system: 1. Introduction: Automotive air conditioning refers to the air conditioning device installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. 2. Structure: Generally includes refrigeration devices, heating devices, and ventilation devices. This combined system makes full use of the limited space inside the vehicle, featuring a simple structure and easy operation, making it a popular modern automotive air conditioning system internationally. 3. Layout: Different types of air conditioning systems have different layout methods. Currently, integrated heating and cooling air conditioning systems are widely used in passenger cars. The typical layout involves assembling the evaporator, heater core, centrifugal blower, and control mechanism together, known as the air conditioning unit assembly.

What's the matter when there is no sound in the car?

Car without sound should be a line connection problem. If the car suddenly has no sound, first check whether the power supply of the CD player is normal. As long as there is electricity, the indicator light should be on, and the CD player can also be turned on and off normally. If there is no electricity, please check the power supply, that is, the fuse box and the line. The following is an introduction to the technical indicators of the audio: 1. Output power: The power marked by most of the current hosts is the music power, between 40W and 60W, and the power should not be too large. 2. Frequency response: The frequency range that the human ear can hear is between 20Hz and 20KHz, so this indicator should at least reach this value, and the wider the better. 3. Signal-to-noise ratio: This indicator refers to the ratio of the music signal to the noise. Generally, high-end car audio is above 90DB, and the larger the value, the better. 4. Harmonic distortion (THD): This indicator reflects the degree of sound reproduction. The smaller the value, the higher the degree of reproduction, and the better the sound effect.

Why Can't the Volkswagen Lavida Key Turn and Start the Car?

If the Volkswagen Lavida key can't turn, it might be due to the steering wheel being locked. Additional information: 1. Suggestion: Try turning the steering wheel while turning the key. If the steering wheel doesn't respond, it could be caused by mechanical key wear. It is recommended to use the spare key to unlock. If the spare key also fails, it is advised to visit a 4S store for inspection and repair as soon as possible. 2. Function: The steering wheel lock is a simple anti-theft feature designed for vehicle security. When the car is turned off, if the steering wheel is turned left or right or the wheels are not aligned when parked, force applied can cause the steering wheel to rotate, triggering the self-locking function. This causes the steering lock pin to engage with the steering column, preventing the steering wheel from moving. Even if the key is inserted and turned forcefully, it won't work. This is the vehicle's anti-theft system detecting a potential theft risk, thus locking the steering wheel to prevent theft.

Can the Mercedes-Benz GLB200 support mobile screen mirroring?

Mercedes-Benz's screen mirroring feature is primarily compatible with Apple iPhones. Simply connect to CarPlay using a data cable (the USB port is located near the cup holder under the center console), and you can then project your phone's screen. For Android phones, this feature is only supported in certain 2019 Mercedes-Benz models. Additionally, you will need to download the Carlife app and use an Android-to-Type-C adapter to connect. Once properly connected, you can use Carlife for screen mirroring. It's worth noting that Apple iPhones supporting CarPlay must be iPhone 5 series or newer, while Carlife requires the phone's operating system to be at least Android 5.0. Carlife is a car networking technology developed by Baidu, currently compatible with multimedia systems such as Linux, QNX, and Android, and supports both Android and iOS phone systems. Its main functions include music playback, precise map navigation, answering and making calls, voice input, data transmission, and more, aiming to achieve seamless interaction between mobile phones and car information.
