Yes. 'Auto' refers to the automatic headlights, which generally do not require manual intervention, and there is no need to turn them off when the engine is shut down. As long as there is sufficient light while driving, the system will automatically turn them off. However, automatic headlights can be quite sensitive at times, and if the owner finds this bothersome, they can also be manually turned off. The automatic headlights will control the switching on and off of the headlights based on the sensitivity to light levels. When 'Auto' is activated, it means the automatic headlights are in the 'on' state. The principle involves using electronic components such as photoresistors as sensors to send signals to the ECU, which controls the headlights' on/off function and the high/low beams. If the light suddenly dims while driving, the headlights will automatically turn on; if the light is sufficient, they will automatically turn off without requiring manual operation. Of course, because automatic headlights can be quite sensitive, they may sometimes turn on during the day. If the owner finds this troublesome, they can manually turn them off. After the car is turned off, if some electrical appliances are not switched off, they will continue to consume the battery's power. Once the car is turned off, the alternator stops working, and the only source of power for the entire vehicle is the battery. If some electrical devices are left on for an extended period, it can lead to battery depletion, shorten the battery's lifespan, and also affect the engine's ability to start.

How to Fix a Seat Belt Lockup?

Seat Belt Lockup Repair Method: The seat belt retractor mechanism needs to be disassembled and replaced. There are some components inside the seat belt retractor mechanism that, if malfunctioning, can cause the seat belt to get stuck—unable to be pulled out or retracted. If the seat belt cannot be pulled out or retracted, or fails to lock during rapid pulling, it is essential to take the vehicle to a 4S shop for immediate repair. Principle of Car Seat Belts: Seat belts can stretch and retract. When the belt is not tightened, the body can lean forward easily. However, during a vehicle collision or when the body jerks forward rapidly, the seat belt will suddenly tighten and securely hold the body in place, ensuring the safety of the driver and passengers.
