Coasting in neutral

很多开手动挡的司机，为了省油，喜欢在下坡或者遇到前方是红灯的情况下挂空挡滑行，如果是在市区行驶、车速不快的情况下，安 全隐患倒不是特别大，但是手动挡车型在车速快时，是非常不建议空挡滑行的。因为空挡滑行无法利用发动机制动来限 制车速，遇到长下坡的情况容易因为刹车热衰减而导致刹车失灵，有大的安 全隐患。而对于自动挡车型，空挡滑行时目前绝大多数的电喷发动机为了保持怠速仍然会自动喷油，所以并不省油。

In order to save fuel, many drivers who drive in manual gear like to slide in neutral when they are going downhill or when there is a red light in front of them. If they are driving in the urban area and the speed is not fast, the potential safety hazard is not particularly big. However, when the speed is fast, it is not recommended to slide in neutral when the speed is fast. Because the engine braking can not be used to limit the speed in neutral taxiing, it is easy to cause the brake failure due to the thermal attenuation of the brake in case of long downhill, which has a big potential safety hazard. For the automatic transmission vehicle, when coasting in neutral gear, the vast majority of EFI Engines still inject fuel automatically in order to maintain idle speed, so it does not save fuel.

停车位不平整

Uneven parking space

有些车主经常一半车轮停在路肩上，长期这样停车，会导致四轮落差过大，可能会造成车架扭曲，甚至影响到车门的闭合。此外，总是在停车后不回正车轮，可能会伤害方向机拉杆及防尘套，影响转向系统。

Some car owners often park half of their wheels on the shoulder of the road. If they park in this way for a long time, the fall of the four wheels will be too large, which may cause the frame to twist and even affect the closing of the door. In addition, always do not return to the right wheel after parking, which may damage the steering linkage and dust boot and affect the steering system.

频繁打火

Frequent lighting

对于没有自动启停功能的车辆来说，每次停车就熄火并不省油，因为电瓶并没有做相应的性能提升。因此，打火次数越多，电瓶负担越大。有的车有时打不着火，一些车主就一直频繁打火。这种情况下，等待20秒左右，进行再一次的打火！否则蓄电池频繁向起动机提供强大电流会造成其自身的损耗。

For vehicles without automatic start stop function, it's not fuel-efficient to turn off the engine every time they stop, because the battery doesn't improve its performance. Therefore, the more times of lighting, the greater the burden on the battery. Some cars can't catch fire sometimes, and some car owners have been lighting up frequently. In this case, wait about 20 seconds for another light! Otherwise, the battery often provides strong current to the starter, which will cause its own loss.

过减速带不减速

Do not slow down after passing the speed reduction belt

很多车主仗着自己底盘高，悬挂好，总是飞一般经过减速带或者不平的路面。虽然车辆本身有悬挂系统，可以减少车内人的颠簸感，但是这都是以减少悬挂系统和轮胎寿命为代价的。高速经过减速带多少都会对车辆悬挂系统的金属部件造成损伤。另外，高速经过减速带或者上路坎都会对轮胎内部的钢丝线造成大的冲击，一旦钢丝断裂出现鼓胎现象，那就离爆胎不远了！

Many car owners rely on their high chassis, good suspension, always fly through the deceleration belt or uneven road. Although the vehicle itself has a suspension system, which can reduce the bumpiness of the occupants, it is at the cost of reducing the suspension system and tire life. The metal parts of the vehicle suspension system will be damaged when passing through the deceleration belt at high speed. In addition, high speed through the deceleration belt or on the road sill will cause a big impact on the wire inside the tire. Once the wire fracture occurs tire bulge phenomenon, it is not far from the tire burst!
