What must I do before the car stops?

The correct way to turn off the car is to park the car in the same place, put on the brakes, put on N gear, pull the handbrake and try to release the footbrake. If you don't slip, you can put in P gear and turn off the engine. Why don't you just hang the P file? Because it is difficult for the handbrake to control the car from slipping, you can put the car into high gear without stepping on the brake and releasing the throttle, and then release the throttle. The high gear can stop the car, and the oil will automatically turn off when it is dry. You can drive the car up a steep slope or into a ditch, or the order of driving water is to protect the P gear from locking. Some drivers push directly to the P gear, which has little influence on the flat road surface and has influence on the uneven road surface.

Actually, it's easy to turn off the automatic transmission. There are not so many complicated procedures. Just pull the handbrake after parking, and then shift directly from D to P.. Turn off the engine, get out and leave. The so-called methods of changing the N gear first, then stalling, and then changing the P gear are all idling. You don't need to put the N gear here, just put the P gear handbrake directly. Some people may ask, will this damage the gearbox? I'll give you a definite answer now. Parking on a flat road is as simple as that, and it won't hurt the gearbox. Moreover, the current automatic auto start can only be started by stepping on the brakes, which will not pose a potential threat to the gearbox. First of all, let's talk about the parking order of automatic cars. When an automatic car drives to a predetermined place, brake and stop, and then tighten the handbrake to ensure that the car does not slip, it can be directly put into P gear and turned off. Some people say that an automatic car needs to enter N gear first, and then turn off and then enter P gear. This wave of operation is meaningless and unnecessary. The manual gear is easy to open and close. If you put it in a high gear and suddenly release the clutch, it will basically stall without stepping on the accelerator. Because the load of the engine is greater than the power output of the engine, it is inhibited from shutting down. This will not happen in the normal use of automatic transmission. But in some cases, it can really be shut down artificially.
