BMW 320 Cooling Activation Method: Press the cooling function button, which represents the air conditioning button, to turn it on. After the cooling function is activated, the air is cooled, dehumidified, and reheated according to the set temperature. Related details are as follows: 1. After the engine starts, under certain climate conditions, a layer of condensation may form on the windshield for a short period. The refrigerant continuously expands in the evaporator box, absorbing heat. After absorbing heat, the refrigerant cools the evaporator box, which in turn cools the air blown by the blower, allowing cold air to be emitted from the air conditioning vents. 2. Most vehicle air conditioning systems use R134a refrigerant, which requires regular replacement. If the refrigerant is not replaced for a long time, it will affect the cooling speed and effectiveness of the air conditioning system.

What does car braking mean?

Car braking refers to the braking technology used to decelerate or stop a vehicle during driving. The main factors affecting a car's braking performance include the following: Road friction coefficient: For example, heavy rain, water accumulation, or snowy conditions can all extend the braking distance. Vehicle weight: This includes both unladen and fully loaded conditions. Generally, the braking distance of a vehicle is tested under unladen conditions. The heavier the vehicle, the greater the inertia, the longer it takes to stop, and thus the longer the braking distance. Factors related to the braking system itself: Such as whether the braking force is sufficient, the system's reaction time, whether the vehicle is overloaded, as well as the condition of the tires and tire pressure.

Is it mandatory to purchase new car insurance at a 4S dealership?

Whether new car insurance must be purchased at a 4S dealership depends on the situation. For cars purchased with consumer loans at a 4S dealership, if the bank or financial institution has mandatory requirements, you must purchase the specified insurance when picking up and registering the vehicle. The following are considerations when purchasing insurance: Choosing an insurance company: If you choose to purchase car insurance yourself, the first step is to find a suitable insurance company. Be cautious when selecting small insurance companies, especially those that are not well-known. This is because claims settlement can be difficult and troublesome with such companies, and their limited nationwide service networks may cause car owners to waste a lot of time on procedures. Selecting insurance items: When insuring a new car, choosing the right items is crucial. The first item to purchase is vehicle damage insurance, which offers high cost-effectiveness and covers minor scratches and collisions. Next is third-party liability insurance, which serves as an excellent supplement to compulsory traffic insurance. It costs slightly more but provides significantly higher coverage. Additionally, if you don’t have a garage or a fixed parking space, theft insurance is necessary. Other additional insurances can be selected based on your needs. Points to note regarding purchasing methods: Currently, the more common methods for purchasing car insurance are phone-based and online insurance. Both are much cheaper than traditional car insurance and are very convenient, allowing you to handle vehicle insurance without leaving your home. You can also call the official PICC hotline for consultation.
