①P Parking block: Parking blocks are generally used for long-term parking, and cars should be in a stopped state when put into parking blocks.

②R reverse gear: The reverse gear is behind the parking gear, and the car can only be put into gear when parking.

③N Neutral: Neutral is located behind the reverse gear, and the engine power of the car cannot be transmitted after being engaged in neutral, which is generally used for short-term parking.

④D forward gear: When the automatic transmission works automatically while driving, the driver only needs to control the acceleration and deceleration.

①S fitness gear: In S gear mode, the transmission can shift gears at will. During the whole driving process of the vehicle, the gear handle is immediately sent to the S gear, which is generally used for uphill and high-speed driving.

②L Low gear: Low gear is one of the forward gears, which can be used in long downhill or downhill, but it should be noted that the speed should not be too high.

③M manual gear: Manual mode can bring a lot of driving pleasure to drivers, and at the same time, it has stronger adaptability to complex real-time road conditions.

④B Brake system gear: generally used for long-distance running or downhill, the purpose is to give the brake system a function and recover its lifting kinetic energy, which can bring the purpose of charging the automobile power battery and improving the battery life.

Practical operation method of modern Shengda gear shifting

1, gear selection under different road conditions

① Starting uphill: This road must be intervened with high torque, and "D-" building blocks can be used. But sometimes when the power is abundant, it is necessary to use "D" to upshift, so as to avoid power consumption endangering the automobile engine and its transmission. Assuming steep slope, manual downshift or insufficient power, S gear is needed.

② Downhill: Shift to D2 or D3 with "D", which can contain the automobile engine and achieve the actual effect of the braking system. 1 gear has great torque, and generally, gear 2 and gear 3 can achieve good containment effect. When the car can't control the decline on the downhill section, the "D-" downshift constraint should be applied again.

2. Application of paddle shifting.

Step on the brake pedal first, change the gear to "D" first, and then push the gear handle to the front seat. At this time, the elevator gear can be developed according to the ""and "-"tabs of the automobile steering wheel. Manual mode is more in line with the driver's habit, and shift gears in time.
