Does the BMW 525 Have Automatic Parking Function?

BMW 525 is equipped with an automatic parking function. When using the automatic parking feature, the vehicle speed should be below 35km/h. To activate it, press the automatic parking assist button located to the left of the electronic handbrake button, which will automatically detect parking spaces on both sides of the road. This system only supports parallel parking on the left or right side. How to use the BMW 525 automatic parking function: Press the PDC button to turn on the automatic parking function and ensure that it is indeed activated. Drive at the required speed, allowing the ultrasonic sensors to effectively detect parking spaces. If a suitable parking space is detected, the central display screen will show a "Please Stop" prompt. Bring the vehicle to a stop, and the system will prompt you to choose between parallel or perpendicular parking. Then, select accordingly based on the situation. Precautions: During automatic parking, the driver must pay attention to the surroundings. If any abnormalities are detected, immediately apply the brakes manually or release the PDC button to exit the automatic parking mode. Before starting automatic parking, always remember to turn on the turn signal. Ensure to fasten the seatbelt; otherwise, the automatic parking function cannot be activated.

Which Has Greater Density: Water or Gasoline?

Water has greater density. The density of water is approximately one kilogram per cubic meter, while the density of gasoline is about eight kilograms per cubic meter, though it may vary due to seasonal factors. Below is some relevant information about gasoline and water: 1. Density of different gasoline grades: The density varies among different gasoline grades. The most common are 92-octane and 95-octane gasoline. The density of 92-octane gasoline is approximately 0.72 g/ml, 95-octane gasoline is about 0.725 g/ml, and 98-octane gasoline is around 0.737 g/ml. 2. Octane rating: Higher-octane gasoline contains more additives, and these additives have a greater density than the base gasoline. Therefore, the higher the octane rating, the greater the density of the gasoline. The reason gasoline has octane ratings is primarily due to the varying anti-knock properties of different grades, not because higher-octane gasoline has fewer impurities. The higher the octane rating, the better the anti-knock performance, meaning the engine is less likely to experience premature combustion during operation.

Why can't mobile phones be used in gas stations?

Mobile phones cannot be used in gas stations because when a phone is in use, it generates a very weak discharge inside, producing tiny sparks. If the concentration of gasoline vapor in the air near the gas station is too high, these sparks could potentially cause an explosion. Therefore, mobile phone usage is prohibited in gas stations. Here are some additional precautions to take at gas stations: No smoking: The surface temperature of a cigarette butt is typically between 200 to 300 degrees Celsius, which can easily ignite gasoline. Gas stations are surrounded by a high concentration of flammable gas molecules, and even the smallest spark can lead to a fire or explosion. Turn off the engine while refueling: When a vehicle is running, the flow of exhaust gases and minor wear on electrical wiring can generate static electricity or sparks, especially in humid weather when gasoline vapor concentration increases, raising the risk of ignition. Avoid patting synthetic fiber clothing while refueling: Synthetic fabrics are prone to generating static electricity, so avoid getting out of the car and patting your clothes to prevent unforeseen hazards. No vehicle repairs in the gas station: High-temperature engine components or electrical leaks in the pressure system during repairs can cause fires, especially in cases of electrical short circuits, which are particularly dangerous.

How to Duplicate a Key Without the Original?

You can duplicate a key by providing the vehicle owner's ID and vehicle documents to either a 4S dealership or a regular key duplication service. Below are solutions for lost car keys: 1. Use the spare key: Generally, cars come with two keys—one for regular use and another as a spare. If the primary key is lost, the spare can be used. Therefore, always remember not to keep the spare key inside the car; store it in a safe place at home. Otherwise, if both the primary and spare keys are lost or left inside the car, you’ll need to call a locksmith. 2. Hire a professional locksmith: If the vehicle is far from the spare key or the spare key is also missing, you’ll need to contact a professional locksmith. Typically, you’ll need to provide relevant documents such as your ID and vehicle registration. 3. Get a new key from a 4S dealership: Each vehicle comes with a unique anti-theft code. By providing your driver’s license and ID to the dealership, they can retrieve this code and create a new key. Additionally, they can deactivate the lost key, rendering it useless for starting the car (though it may still unlock the doors). For added security, the dealership may recommend replacing all the locks in the vehicle.
