In daily life, the driving habits are also different for each car owner, whether driving an automatic or manual car. The driving technology of the owner is also different, of course, the function of the car facing the owner is the same for the same car, and the result is also different for two different people driving the same car.
Regarding the automatic car, it does provide a lot of convenience for the owner in the daily life, especially some of the configurations of the automatic car are also particularly humanized. So what does the "+""-" file above it mean?

In the daily operation of the automatic car, most of the drivers are accustomed to using the D gear operation, but also call this universal gear, no matter at any time like to use it sexually, then there is no clutch about the automatic car. In daily operation, you only need to hang the gear in d gear to participate.
But for the addition and subtraction symbols on the automatic car, it is also an indirect indication that this model is a manual mention of the gearbox. For such a model, the driving pleasure brought to the owner on a daily basis is more than that of other automatic cars, especially when facing the uphill and downhill sections. Manual mode can be used, if from such an operation, in fact, it is very similar to the manual car.
Regarding these two symbols, the meaning of the surface of the + sign is the meaning of upshift, which is to upgrade, and the meaning of the surface of the -sign is the meaning of reduction, which is to downshift. About these two symbols in the daily operation can play a role in fuel saving purposes, especially in the start of this operation, many car owners will use the manual first gear to start, with the car started, you can raise the gear to the second gear. Wait until the vehicle has been running normally for a period of time before it can return to the official gear. Owner: Not in vain
When operating daily, the selection of gears in the face of different speeds is also different, if you feel that the speed is relatively slow, you can choose the "+" number to push up. If it is currently pushed up in the second gear, it will be directly upgraded to the third gear. So the same reason, for the "-" sign is also the same reason, if the current gear is three gears, then choose the "-" sign, it will be directly down to the second gear.
In fact, about the automatic transmission of the hand, the role played in daily life is still very much, for example, when the speed of their own vehicle is relatively low, forget the operation of downshifting, it will automatically help you operate, saving the owner from operating again.
