What does it mean when the engine oil light stays on after a car self-check?

It is normal for the engine oil light to stay on after a car self-check. The light will turn off once the engine is started. If the light remains on after starting the engine, you should check whether the engine oil level is sufficient. A car self-check refers to the process when the car is first started, during which various indicator lights on the dashboard will illuminate for 2 to 3 seconds before turning off automatically. If any indicator light remains on, it indicates a fault in the corresponding system of the car, requiring attention. For example, if an oil can symbol appears, it means you need to add engine oil. After adding oil, start the vehicle and check the oil level again after turning off the engine for 3 minutes. This is because when changing the engine oil, the oil filter also needs to be replaced. The new oil filter initially contains no oil, so after starting the vehicle, oil will flow into the oil filter.

How to Set Up Auto-Lock for Car Doors?

Method to set up auto-lock for car doors: The auto-lock function setup differs between automatic and manual transmission models, but generally involves holding the ignition switch and pressing the lock button for about 5 seconds until the hazard lights flash twice, indicating successful setup. The purpose of the auto-lock feature is anti-theft, allowing doors to lock quickly after driving starts to prevent door-pull robberies during traffic jams or at red lights, providing a certain level of security. It also protects child passengers inside the car by preventing young children from opening the door handles while the vehicle is in motion. When the vehicle speed reaches a preset value (usually set by the manufacturer, typically between 10 to 20 kilometers per hour), the lock button will automatically engage to prevent accidental door opening. This is a common auto-lock method used in many car models (such as Volkswagen, Audi, BMW, Mercedes-Benz, Hyundai, etc.).

The functions of a transmission are: 1. To alter the transmission ratio, meeting the traction needs under various driving conditions and enabling the engine to operate under favorable circumstances; 2. To allow the car to move in reverse; 3. To interrupt power transmission, such as when the engine is started and idling, when the car is shifting gears or parked, cutting off power to the drive wheels; 4. To achieve neutral gear, stopping the transmission's power output when the clutch is engaged. The functions of a manual transmission are: 1. To change the transmission ratio, expanding the range of torque and speed variations for the drive wheels; 2. Under the premise that the engine's rotation direction remains unchanged, to use the reverse gear to enable the car to move backward.
