Below are the operating instructions for the air conditioning in the older BMW 5 Series: 1. Press the A/C button to activate the BMW 5 Series air conditioning system. The indicator light in the button will illuminate. Press the button again to turn off the compressor, and the indicator light will go out. 2. If the air conditioning performance is lower than expected, check the surface of the air conditioning condenser (located in front of the radiator) for dirt or insect buildup. Please visit a BMW 5 Series service station for cleaning. Placing obstructions in front of the engine hood will reduce airflow to the condenser, thereby lowering air conditioning performance. 3. After activating the external air circulation in the BMW 5 Series, the air intake located at the firewall will be opened by the air conditioning computer. The blower inside the vehicle will draw outside air through the micro-dust filter into the two heat exchangers (cooling and heating) inside the evaporator. The air processed by the heat exchangers will then be blown out through the vents. When the external circulation mode is activated, the air intake opens, connecting the air inside and outside the vehicle. For example, when encountering traffic congestion in the city, you can turn on the external circulation mode.

What is the emission standard for vehicles from 2012?

Vehicles from 2012 are generally classified as China IV emission standard, with a small portion meeting China V standards. The methods to determine China IV emission standards are as follows: 1. The simplest and most direct way is to check the vehicle's environmental protection label, which has a clear mark on the back. 2. Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire. 3. Bring the vehicle registration certificate (original or copy) to the vehicle management office for inquiry. 4. For new vehicles, check the vehicle's factory certificate of conformity. Generally, the vehicle's certificate of conformity is kept at the vehicle management office. A rough distinction can be made based on the year of vehicle registration: 1. Vehicles registered after 2015 are mostly China V. 2. Vehicles registered after 2008 are mostly China IV. 3. Vehicles registered in 2007 may be either China III or China IV. 4. Vehicles registered before 2007 are mostly below China IV, i.e., China II or China III. 5. Vehicles registered before 2005 are mostly China II.

What to Do When Engine Oil Increases, Emulsifies Severely, and Has a Strong Gasoline Smell?

For hybrid version vehicles, increase the engine temperature by letting the engine work, drive on highways, and add some long-distance driving. For fuel version vehicle owners, try to warm up the car before driving, allowing at least 30 seconds of warm-up time. This helps solve the issues of severe oil increase, emulsification, and gasoline smell. Below is extended information on oil emulsification: 1. Oil emulsification refers to the phenomenon where ordinary engine oil turns milky yellow or milky white. It is a common occurrence, especially in winter when temperatures are low, and many northern regions experience oil emulsification problems. 2. Check the oil dipstick every two to three months. For vehicles equipped with direct injection engines, in areas with high urban humidity, low temperatures, and short driving distances each time, the inspection cycle should be shortened accordingly. 3. When checking the vehicle, ensure it is parked on a flat surface without any slope. Wait at least one hour after parking to allow all the oil to return to the oil pan before pulling out the oil dipstick.

What is the purpose of wheel alignment for sedans?

Since the installation of car tires, steering mechanisms, and front and rear axles requires specific angles and relative positions, adjusting the angles and positions between the chassis and tire components is known as wheel alignment. The functions of wheel alignment are as follows: 1. Protect the tires. Wheel alignment ensures that the tires and the vehicle body maintain the optimal angle, improving traction and ensuring comfort. 2. Enhance handling. Properly aligned tires contribute to driving safety and stability, especially in emergencies where sufficient traction is maintained, allowing the vehicle to follow the driver's intended path as closely as possible. 3. Save fuel. Fuel consumption is closely related to the tires. The smaller the rolling friction coefficient of the tires, the lower the vehicle's resistance and fuel consumption. 4. Improve safety. Well-maintained tires enhance overall vehicle performance and significantly increase safety. During the wheel alignment process, maintenance technicians also inspect the vehicle's suspension system and other components, which helps determine whether the tires have any adverse effects on the chassis system.

How Many Kilometers Should Car Spark Plugs Be Replaced?

Under normal maintenance conditions, car spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. The following standards can be referenced for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its appearance to assess its condition. A normal spark plug will have an insulator skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug will have a reddish-brown insulator skirt, an electrode gap between 0.8-0.9mm, and no signs of electrode burning. If the spark plug is covered in oil or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, with signs such as blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified and the issue resolved before replacing the spark plug. Additionally, if the spark plug appears black as if smoked, it indicates that the wrong heat range was selected or that the air-fuel mixture is too rich, or that oil is leaking into the combustion chamber.
