What is the function of the A next to the handbrake?

The function of the 'A' symbol next to the electronic handbrake is: the Auto Hold system (AUTOHOLD). After turning on this switch, when the vehicle comes to a stop during driving, even if you release the brake pedal, the vehicle will not continue moving. It will only resume driving when you press the accelerator, at which point the system automatically cancels. If you want to turn it off, you must do so manually. The Auto Hold system is a technological application that enables automatic handbrake functionality while the car is in operation. This technology allows drivers to avoid prolonged braking when the vehicle is stopped and prevents unnecessary vehicle slippage when the automatic electronic parking brake is engaged. Compared to traditional manual mechanical parking brake systems, the Auto Hold system offers the following advantages: The parking brake handle inside the cabin is eliminated, providing more design flexibility for the vehicle's interior styling. The parking brake is replaced by a button, simplifying the operation and reducing effort, which lowers the operational intensity for drivers, especially female drivers. With the continuous development of automotive electronic parking control technology, this system not only achieves basic functions such as static parking, static release (turning off), and automatic release (turning off) but also includes additional auxiliary functions like auto hold and dynamic parking.

I've been driving for so many years and often get asked about the purpose of the A button next to the handbrake. Actually, it controls the auto start-stop system, which means the engine automatically shuts off when the car is stationary to save fuel. For example, when waiting at a red light and pressing the brake, the car will shut down automatically; stepping on the accelerator instantly restarts it. This design is mainly for environmental protection and fuel economy. Since my car got this feature, I've saved quite a bit on monthly fuel costs. However, there are minor issues, like in heavy stop-and-go traffic, frequent engine restarts can put a strain on the battery. So, I sometimes manually turn it off to extend its lifespan. Its location next to the handbrake is very handy, and operating it doesn't distract from driving. Overall, it's a great feature that makes driving much easier once you get used to it.

What to Do If the Windshield Washer Fluid of Geely Boyue Doesn't Spray High Enough?

If the windshield washer fluid of Geely Boyue doesn't spray high enough, you can adjust it by inserting into the nozzle. Windshield Has Oil Film: When the vehicle is exposed to the natural environment, the tiny pores on the glass will enlarge, and over time, they will absorb exhaust fumes and oil mist from the air, forming an oil film. It's difficult to remove the oil film solely by relying on the wiper and washer fluid; an oil film cleaner must be used to eliminate it. Wiper Arm Deformation: The motor drives the deceleration mechanism to rotate, which in turn moves the wiper arm and wiper blade left and right to clean the windshield. If the wiper arm is deformed, causing the wiper blade to fail to adhere tightly to the windshield, it won't be able to remove dirt. In this case, a new wiper should be replaced.

Where to Add Windshield Washer Fluid in an Audi?

Audi windshield washer fluid is added in the washer fluid reservoir located in the front engine compartment, which is marked accordingly. Usage of the windshield wipers: By pushing the control lever up or down, you can control the wiper operation modes (single wipe, off, auto, and low/high speed). If set to auto mode, you can adjust the sensitivity of the rain sensor-controlled wipers by rotating the adjustment knob, thereby changing the wiper frequency. For windshield washing, gently pull the control lever toward the driver to activate both the windshield washer and wipers simultaneously. Precautions for using windshield wipers: If you notice that the washer fluid is not spraying out while the wipers are operating, do not continue pressing the button. Instead, check if the washer fluid warning light is illuminated. If it is, promptly refill the washer fluid.

At what mileage should the spark plugs be replaced for a BMW 5 Series?

BMW 5 Series spark plugs should be replaced every 40,000 kilometers. The vehicle uses NGK platinum spark plugs, with the model number ILZKBR7B8DG. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high voltage into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. They are installed on the side or top of the engine, with the ignition coil directly connected to the spark plug. Replacement interval for spark plugs: Under normal maintenance conditions, they should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the owner's manual. You can refer to the following maintenance standards for 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.

Fuel tank capacity: Generally, the fuel tank capacity of small cars is 35-45 liters, while that of mid-size cars is about 55-75 liters. A full tank usually allows a car to travel about 500 kilometers. The size of the fuel tank depends on the car's displacement and fuel consumption—larger fuel tanks are for cars with higher fuel consumption, and smaller tanks are for those with lower fuel consumption. The design of a car's fuel tank capacity generally allows for a range of 400-600 kilometers. Lighter cars with smaller displacements have correspondingly smaller fuel tanks, while heavier cars with larger displacements naturally have larger fuel tanks. However, most full tanks provide a maximum range of 400-600 kilometers. Fuel tank capacity measurement unit: Internationally, the standard unit for measuring a car's fuel tank capacity is liters (L). Different countries also have their own standards for fuel tank capacity.

At how many kilometers should the spark plugs be replaced for a BMW 5 Series?

The replacement cycle for spark plugs in a BMW 5 Series is 40,000 kilometers. If the spark plugs are not replaced for a long time, it can lead to various issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in ignition, which affects the normal use of the vehicle. Spark plug replacement cycle: Under normal maintenance conditions, replacement is recommended between 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is advisable 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. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, and remove the high-voltage distributor wires. Mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires according to the ignition sequence and secure the cover.
