Misunderstanding 1; Automatic transmission car as long as D gear start, has been increasing the accelerator can shift to high speed (gear);

有些驾驶员认为只要D挡起步，一直加大油门就可以换到高速挡，殊不知这种做法是错误的。

Some drivers think that they can shift to high speed as long as they start in D gear and increase the accelerator all the time, but they don't know that this is wrong.

因为换挡操作应是“收油门提前升挡，踩油门提前降挡”。也就是在D挡起步后，保持节气门开度5%，加速到40km／h，快松油门，能提高到一个挡位，再加速到75km／h，松油门又能提高一个挡位。降低时按行车车速，稍踩油门，即回到低挡。但必须注意，油门不能踩到底。否则，会强行挂入低速挡，可能造成变速器损坏。

Because the shift operation should be "throttle up in advance, throttle down in advance". That is to say, after starting in D gear, keep the throttle opening at 5%, accelerate to 40km / h, quickly release the throttle, and then increase to a gear. When accelerating to 75KM / h, release the throttle, and then increase to a gear. When lowering, press the driving speed and step on the accelerator slightly to return to the low gear. But it must be noted that the accelerator can not be pressed to the end. Otherwise, it will be forced into low gear, which may cause damage to the transmission.

总之，自动变速器汽车相对于手动变速器汽车而言，省去了离合器踏板，不必频繁地踩踏板，使汽车驾驶变得简单、轻松。但若操作不当，会人为地增加自动变速器的故障发生率，降低其使用寿命。正确使用自动变速器，不仅可以避免或减少故障的发生，还会降低油耗，减少污染。

In a word, compared with the manual transmission vehicle, the automatic transmission vehicle saves the clutch pedal and does not need to step on the pedal frequently, which makes the vehicle driving simple and easy. However, improper operation will artificially increase the failure rate of automatic transmission and reduce its service life. Correct use of automatic transmission can not only avoid or reduce the occurrence of faults, but also reduce fuel consumption and pollution.

误区2；自动变速器车辆高速行驶或下坡时，把换挡杆拨在N档位滑行；

2; When the automatic transmission vehicle is driving at high speed or downhill, set the shift lever to n gear to slide;

有些驾驶员为了节油，在高速行驶或下坡时，将换挡杆拨到N挡滑行，这很可能烧坏变速器。因为此时变速器输出轴转速很高，而发动机怠速运转，变速器油泵供油不足，润滑状况恶化，而且对变速器内部的多片离合器来说，虽然动力已经切断，但其被动片在车轮带动下高速运转，发动机驱动的主动片转速很低，两者间隙又很小，容易引起共振和打滑现象，产生不良后果。当下长坡确需滑行时，可将换挡杆保持在D挡滑行，但不可使发动机熄火。

In order to save fuel, some drivers shift the gear lever to n when driving at high speed or downhill, which may burn the transmission. At this time, the speed of the output shaft of the transmission is very high, while the engine is idling, the oil supply of the transmission oil pump is insufficient, and the lubrication condition deteriorates. For the multi plate clutch inside the transmission, although the power has been cut off, its passive plate runs at high speed driven by the wheels, and the speed of the active plate driven by the engine is very low, and the gap between the two is very small, which is easy to cause resonance and slip, There are bad consequences. When it is necessary to slide down the long slope, keep the shift lever at d gear, but do not turn off the engine.

误区3；自动变速器车辆坡道停车时不使用驻车制动；

3; Automatic transmission vehicles do not use the parking brake when parking on a ramp;

装有自动变速器的汽车在坡上停车时，有些驾驶员只是使用P挡，而不使用驻车制动，这样做极容易引发事故。因为虽然装有自动变速器的汽车在P挡位设有的停车锁止机构一般是很少失效的，但一旦失效就会造成意外事故。因此，在坡道停车时，还是应该使用驻车制动器。

When a car with automatic transmission stops on a slope, some drivers only use p gear instead of parking brake, which is very easy to cause accidents. Because although the parking lock mechanism of the car with automatic transmission in P gear is rarely invalid, once it fails, it will cause accidents. Therefore, when parking on a ramp, the parking brake should be used.
