What is the function of the car hold button?

[Karen]

The function of the car hold button is to adjust the optimal driving state according to different driving conditions. The hold button is a derivative function of electronic parking, which effectively prevents frequent gear shifting of the transmission on poor road surfaces and plays a role in forced downshifting during overtaking. Using this button will not cause damage to the transmission. The hold button is a measure to prevent the vehicle from rolling back during short-term parking on slopes or in traffic jams. The function needs to be activated before each use. Even in D gear, there is no need to keep pressing the brake. To release it, simply step on the accelerator, and it will automatically disengage when the driving force exceeds the resistance, so there is no need to shift the gear to neutral. For long-term parking, it is best to shift the gear to neutral or P gear and engage the handbrake system.
