Can the car be locked without turning off the engine?

[VanJosiah]

When the vehicle is not turned off, the doors cannot be locked. Even if some car models can lock the doors without turning off the engine, they will automatically shut off after locking. Preventing forgetting to turn off the engine when exiting the car: Before getting out, check if the display screen has turned off and darkened, and if the tachometer reads zero. When setting the steering wheel position, avoid setting it at the highest position so that when parking and turning off the engine, the steering wheel will rise. Turn on the daytime running lights; in the light settings, enable the daytime running lights, and after locking the door, check them. If the daytime running lights are off, it indicates the engine is turned off. Hazards of not turning off the car engine: When the car is idling, it is in a rich fuel injection state. Prolonged idling can cause carbon buildup in the engine.
