Passenger airbag deactivation is a normal phenomenon. The passenger airbag in this vehicle can be manually turned off, so this "fault" simply indicates the airbag is in the deactivated state. Airbag service life: Beyond requiring replacement after deployment, airbags cannot remain functional indefinitely alongside the vehicle. As a critical automotive component, their lifespan doesn't necessarily match the car's longevity. Standard airbags are designed for 8-10 years of service. However, with updated vehicle retirement policies, many cars now remain operational for over a decade. Airbag system composition: The automotive airbag system consists of sensors, the airbag module, indicator lights, and an electronic control unit. While the airbag operates, a secondary monitoring system tracks its performance. The inflation process relies on chemical reactions to generate gas - these compounds can degrade with moisture exposure. Additionally, electrical connectors, grounding points may loosen over time, and sensors can fail.

What does the letter G on a new energy vehicle license plate mean?

Currently, there is no new energy vehicle license plate with the letter G. To better implement the development and differentiated management policies for the new energy vehicle industry, the Chinese government has adopted a segmented management approach for new energy vehicle license plates based on different vehicle types. The letter "D" represents pure electric vehicles, while the letter "F" represents non-pure electric vehicles. For small vehicles, "D" or "F" appears as the first character in the license plate number sequence; for large vehicles, "D" or "F" is placed as the last character in the license plate number sequence. License plates, commonly known as vehicle plates, are panels mounted on the front and rear of a vehicle, typically made of aluminum, sheet metal, plastic, or paper, displaying the vehicle's registration number, registration region, and other relevant information. License plates serve as identification and information registration for vehicles, allowing people to identify the vehicle's region of registration and access details about the owner and registration information through the license plate.

Can the car air conditioning only be used when the car is running?

Car air conditioning can only be used when the car is running. Here is an extended introduction: 1. Car air conditioning operation: The cold air compressor of the car air conditioning requires the engine to operate to drive it, and the energy for warm air (hot water) is generated only when the engine is warmed up. If you turn on the air conditioning when the car is only powered on but not started, it will not produce any cooling or heating effects. Instead, it will quickly drain the car's battery, ultimately damaging it. 2. Function of car air conditioning: Car air conditioning is used to adjust and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to optimal conditions, providing a comfortable environment for passengers and reducing travel fatigue. It also creates good working conditions for the driver and plays an important role in ensuring safe driving. Generally, it includes cooling devices, heating devices, and ventilation systems. This combined system makes full use of the limited space inside the car, has a simple structure, and is easy to operate, making it a popular modern car air conditioning system internationally.

What to Do If the Baojun 560 Air Conditioning Cooling Effect Is Poor?

Solutions for poor air conditioning cooling effect include cleaning dirty air conditioning filters and radiator condensers, adding system refrigerant, etc. The most common causes and solutions are as follows: 1. Low air conditioning airflow: Check if the air conditioning filter is dirty, whether the blower can operate normally, and if the air conditioning flap motor can switch properly. 2. Lack of refrigerant in the air conditioning system: Check for system leaks. After confirming and repairing, add refrigerant to the standard range. 3. Dirty radiator condenser: Engine cooling system failure, leading to excessively high water temperature, such as the cooling fan not working, resulting in poor heat dissipation of the radiator and condenser.
