What does the auto hold function in a vehicle mean?

[DelLaura]

The auto hold function in a vehicle is an automatic braking feature that provides better driving security for the owner when activated. At traffic lights, the auto hold function simplifies the driver's operations by eliminating the need to pull the handbrake. For automatic transmission vehicles, it removes the need to repeatedly switch between D (Drive) and N (Neutral) gears, thereby enhancing driving safety. Benefits of the auto hold function: 1. In congested urban areas with frequent traffic lights, the auto hold function reduces operational steps, easing the driver's burden and preventing rolling back; 2. On slopes, the auto hold function prevents the vehicle from rolling backward. When starting, it releases the wheels directly for forward movement, eliminating any backward roll.
