Let's talk about how the running-in period started.

First, don't drive the highway. Don't run at high speed in the initial driving stage of a new car. The first stage of the running-in period is the first 100 km, which is the most important period! Shift gears as far as possible within the range of 100 km, but don't drive too hard and drive lightly. The second stage is from 1000 km to1000 km, and the top speed does not exceed 80. The third stage is from 1000 km to 3000 km, and the speed does not exceed 80% of the maximum speed. In addition, it is also required to pay attention to the engine tachometer and speedometer in use, so that the engine speed and speed are working at a medium speed, almost 3000 rpm. 3,000-5,000 kilometers, after the first insurance, you can go to the expressway to remove carbon deposits from the engine. Two-wheel drive and four-wheel drive multi-mode vehicles are switched to use during the running-in period, and the speed is gradually accelerated. Not in the early stage, it will be difficult to use in the running-in period. As we all know, four-wheel drive is worse than two-wheel drive, and there are gears in it, which is actually the same as the running-in method of gearbox. Furthermore, because the four-wheel drive mode and the two-wheel drive mode have different loads on the engine and gearbox, it is suggested that the running-in speed of the four-wheel drive is lower than that of the two-wheel drive, which has a protective effect on the whole vehicle.

Second, don't drive a fully loaded new car. All the parts are just processed. During the running-in period of a new car, a lot of debris will be produced in the engine. Moreover, the damping system and braking system of the transmission system of the new car are brand-new parts, and the joint between them is not very tight and smooth. Running at full load will damage the engine and other parts. Therefore, during the running-in period, it cannot exceed 80% of the rated load. The best way is: don't be full of people in the car during the running-in period, try to ensure that there are only two people in the car, so that you can enjoy the world of two people, haha.

Third, don't run a long distance for a new car unless absolutely necessary, which will increase the continuous working time of the engine and easily lead to increased wear and tear of parts. Moreover, long-distance road conditions are not easy to master, and there are many unexpected situations, which is not conducive to the running-in of new cars. Fourth, don't brake suddenly. Emergency braking will use the traction of the engine to cooperate with the braking system, forcing the high-speed car to stop. This will not only damage the engine, but also increase the load of the chassis, which is not good for the brakes and chassis. Besides, during the running-in period, the advantages outweigh the disadvantages by driving slowly!

Fifth, the running-in period should be changed frequently. As mentioned earlier, the running-in period is not only a running-in period of the engine, but also a comprehensive process of gearbox, steering and braking. Gearbox is an important part of running-in after engine. Only when the shifting times are more and the shifting is more stable and reasonable can the gearbox quickly reach the normal working state. In addition to multiple gears, you should also choose the correct gear according to the speed. Try not to use high-speed low-grade driving or low-speed high-grade driving, and medium-speed driving is the best.

Sixth, pay attention to the new car condition instrument is not very stable. You need to pay attention to various tips and water temperatures that appear during driving. Once an abnormality is found, go to SSSS immediately to check it before it happens. Seven, the functions are used. New cars are not just grinding engines, gearboxes, etc. Air conditioning, stereo, skylight ... As long as there is something in the car, it has many uses, including Bluetooth in the car, USB interface and audio port. These parts are new, too, and there is no harm in grinding them. And like air conditioning, after the running-in period, try air conditioning in winter and hot air in summer, and suddenly use it for half a year, it is definitely not good, nor is it good.
