It can be kept on for a long time. The A button in the car is the auto-hold function. After activating the auto-hold function, it can avoid frequent operation of the handbrake or electronic handbrake. Related introduction of auto-hold: Vehicles with electronic handbrakes are generally equipped with the auto-hold function. This function is not enabled by default and needs to be manually activated by the driver. After activating the auto-hold function, it can avoid frequent operation of the handbrake or electronic handbrake, and automatic transmission models do not need to frequently switch between D to N and D to P. When the vehicle is braked to a stop during driving, even if the brake pedal is released, the vehicle may not continue to move. Only when the accelerator pedal is pressed again will the vehicle continue to move forward. The English name of auto-hold is AUTOHOLD, and this button is mostly placed next to the electronic handbrake. The role of auto-hold: When encountering a short stop at a traffic light, the system will automatically brake the wheels after the vehicle stops to prevent rolling; When starting on an uphill slope, the system will automatically brake to prevent rolling back. After starting, the system will automatically release the wheels and move forward directly; When parking and locking, there is no need to pull the handbrake. The system will automatically brake the wheels at this time, but this is only seen in some models.
