What does the 'a' after the electronic handbrake mean?

[MaliaLee]

The 'a' after the electronic handbrake refers to the Auto Hold system. When this function is activated, it allows the driver to avoid keeping their foot on the brake pedal for extended periods when the vehicle is stationary. With the automatic electronic parking brake engaged, it prevents unnecessary rolling of the vehicle. The features of the Auto Hold function include: 1. During driving, when encountering a red light requiring a brief stop, the system automatically applies the brakes to the wheels after the vehicle comes to a halt to prevent rolling; 2. When parking and locking the vehicle, there's no need to pull the handbrake as the system automatically brakes the wheels; 3. When starting on an uphill slope, the system automatically applies the brakes to prevent rolling backward. Once the traction force reaches the level required to move uphill, the system releases the wheels automatically for forward movement.
