Purpose: Enables Audi Hill Start Assist.
Caution: Do not confuse this with Audi Hold Assist, which keeps the vehicle stationary on uphill and downhill slopes for as long as desired. If the vehicle remains stationary for an extended period, the system automatically switches to the electromechanical brake. Audi Hold Assist requires the following button (see image) to activate and deactivate it.
Audi Hill Start Assist is a hill-start assist feature. If you hold down the brake pedal for a certain amount of time while the vehicle is stopped, brake pressure is maintained for a few seconds after you release the brake pedal, making it easier to start on a hill.
