What's the reason for poor air conditioning cooling in BMW 3 Series?

Poor air conditioning cooling in BMW 3 Series may be caused by refrigerant leakage; reduced heat dissipation capacity of the condenser; blocked air ducts or dirty air conditioning pipelines; prolonged use of external circulation, etc. It is recommended to go to a professional repair shop for inspection and treatment. BMW (Bavarian Motor Works), the full Chinese name is Bayerische Motoren Werke AG, a German luxury car brand. BMW's car series include i, X, Z, and pure number models, with several series such as 1, 2, 3, 4, 5, 6, 7, 8. The following are the functions of car air conditioning: 1. Temperature adjustment: This is the main function of car air conditioning. In summer, the cooling system produces cold air to cool the cabin; in winter, except for large commercial vehicles that use independent combustion heaters for heating, other vehicles basically use the car's waste heat for heating. 2. Humidity adjustment: Humidity has a great impact on the comfort of passengers in the car. The humidity in the cabin should generally be maintained at 30%-70%. Ordinary car air conditioners do not have the function of adjusting the humidity inside the car, only through the use of ventilation devices or high-end luxury cars equipped with integrated heating and cooling air conditioners. 3. Airflow adjustment: The speed and direction of airflow greatly affect human comfort. If blowing directly, when the temperature is suitable, the speed should be limited to a certain range. The speed can be appropriately changed according to the passenger's living environment, age, health status, and cold and heat habits. 4. Air purification: The air quality in the cabin is an important guarantee of comfort.

Do Cars Need to Display Insurance Stickers Now?

Currently, cars are required to display insurance stickers. After purchasing compulsory insurance for the vehicle, the insurance sticker should be immediately affixed to the right side of the front windshield. Although some regions have implemented electronic tags, they are not yet widely used, so displaying the vehicle insurance sticker is still necessary for road use. If the insurance sticker is lost, it must be reissued by the insurance company where the policy was purchased. You need to bring the vehicle's registration certificate and the compulsory insurance policy. Once reissued, the sticker should be directly affixed to the right side of the windshield. Losing the insurance sticker requires prompt reissuance; otherwise, driving the vehicle is considered illegal and may result in penalties. In case of an accident, the insurance company has the right to deny claims. According to the Road Traffic Safety Law, failure to display the insurance sticker may result in a one-point deduction from the driver's license and a fine.

Why are pickup trucks not allowed in urban areas?

According to China's laws and regulations, pickup trucks are classified as light-duty ordinary trucks. Most major cities in China, including some second and third-tier cities, impose time and route restrictions on truck traffic. More details are as follows: 1. Pickup trucks entering urban areas may affect the city's image: Many cities prohibit pickup trucks from entering urban areas to maintain a good city image. Additionally, with increasing urban traffic pressure, measures are taken to restrict certain vehicle types. 2. Currently, different regions have varying restrictions on pickup trucks: For example, in Beijing, pickup trucks are managed as trucks and face certain traffic restrictions. From 6:00 to 23:00, freight motor vehicles are prohibited from operating, with specific road sections marked accordingly. For vehicles entering Beijing from other regions, an entry permit is required. 3. Some cities have lifted restrictions on pickup trucks: In recent years, cities such as Taiyuan, Changchun, Nanjing, Fuzhou, Zhengzhou, and Guangzhou have differentiated pickup trucks from other trucks and abolished restrictions on them. Some cities have gradually relaxed time and area restrictions for pickup trucks operating in urban areas.

How to Use the Handbrake When the Automatic Transmission Brakes Fail?

When you find that the vehicle's brakes have failed, first release the accelerator pedal and shift the gear to manual mode, then downshift from high gear to low gear. Automatic transmission vehicles generally do not have as noticeable braking effects as manual transmission vehicles when downshifting. Some models may even prohibit downshifting to protect the transmission. Therefore, you should downshift one gear at a time while using the handbrake to reduce speed before further downshifting. When pulling the handbrake, hold the release button and pull it intermittently, avoiding pulling it all the way at once. Below are the methods to handle brake failure while driving: 1. Identify the problem and slow down in time: It is crucial to develop good driving habits. Even when driving on flat roads, pay attention to the braking condition. Once you notice that the braking distance has increased or the brakes are not working properly, pull over or slow down immediately instead of continuing to drive at high speed. Vehicles on highways should stop in the emergency lane and call for assistance. 2. Use the handbrake wisely to control the vehicle: Before encountering continuous downhill or steep downhill sections, it is advisable to lightly tap the brakes to check their functionality. If the brakes fail, try using the handbrake to stop the car. When pulling the handbrake, avoid yanking it all the way or too quickly, as this may damage the handbrake or cause it to fail. Instead, apply gradual force and pull it slowly to the end. 3. Downshift appropriately to control speed: If the handbrake is slow to reduce speed or fails, promptly attempt to use forced downshifting (commonly known as "gear grabbing") to slow the vehicle with a lower gear. Once the speed decreases, combine it with the handbrake to bring the car to a gradual stop.

Can You Still Drive When the Tire Pressure Monitoring Alarm Goes Off?

Tire pressure monitoring alarm is not recommended to continue driving after. Here are the reasons for the tire pressure monitoring alarm: 1. Tire puncture: A tire puncture usually results in very slow air leakage, which can be measured with a tire pressure gauge. If the tire is low on air, immediately replenish it and then observe the tire pressure warning light. 2. Excessive tire pressure: The standard inflation pressure for passenger car tires is typically specified as follows: standard tires: 2.4-2.5 bar; reinforced tires: 2.8-2.9 bar; the maximum pressure should not exceed 3.5 bar. Therefore, when the tire pressure of any tire exceeds 3.0 bar, it will trigger the tire pressure monitoring light to illuminate.
