①P Parking block: Parking blocks are generally used for long-term parking, and vehicles should stop when put into parking blocks.
②R reverse gear: This gear is used for steering. When steering, the brake pedal is pressed to stop before shifting. Can't engage during driving.
③N Neutral: The transmission is in neutral (waiting for the speed gear), at this time, the force is transmitted to the wheels, and the braking system of the automobile engine cannot play its role.
④D forward gear: used when the vehicle is moving forward, and the forward gear is below neutral.
①S fitness gear: In S gear mode, the transmission can shift gears at will. During the whole driving process of the car, 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: Also known as mechanical energy recovery gear, it generally appears in hybrid or pure electric vehicles. It can also improve the endurance of the vehicle after being put into gear, and at the same time, it can reasonably brake the vehicle when going downhill for a long time.
Practical operation method of Buick Lang Wei shift.
1, application of paddle shifting (some cars)
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, you can also downshift the vehicle according to the "-"downshift tab on the left and upshift the vehicle according to the "-"downshift tab. Manual mode is more suitable for specific driving conditions and accurately controls the torque and speed of the vehicle.
2. Gear selection under different road conditions
① Starting uphill: the slope must have a higher torque support point than usual, and it is suggested to use "D-" to slow down the lifting and twisting. 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: Changing "D" to D2 or D3 will restrict the automobile engine from achieving the actual effect of the braking system. Generally, grade 2-3 should be used for slope inclination. When encountering large slope, pay attention to switch to 1. Similarly, if the vehicle slips faster and faster, it is also necessary to downshift the vehicle according to "D-".
