What does brakehold mean on a car?

[McLiam]

Brakehold on a car refers to the activation button for the auto hold function. The purpose of auto hold is: 1. The driver does not need to brake for a long time, and when the electronic parking brake is activated, it can prevent unnecessary sliding of the vehicle; 2. The vehicle will not roll back when starting on a slope, avoiding the need for the driver to rely on experience and the handbrake to start on an incline. Precautions for using auto hold include: 1. Auto hold can only function properly when the seatbelt is fastened and the doors are closed; 2. When parking, simply pull the handbrake, shift to P gear, and lock the car—there is no need to worry about whether auto hold is activated; 3. The duration of auto hold on an uphill slope is limited, usually two seconds, so it is necessary to apply the throttle promptly after releasing the brake pedal to avoid the risk of rolling back.
