Purpose: to activate Audi Hill Start Assist.
Caution: Not to be confused with Audi Hold Assist, which keeps the vehicle stationary on hills and downhill for as long as required. If the vehicle remains stationary for an extended period, the system automatically switches to electromechanical braking. Audi Hold Assist requires the following button (see image) to activate and deactivate it.
Audi Hill Start Assist is a hill-start assistant. If you hold down the brake pedal for a while when the vehicle is stationary, braking pressure is maintained for a few seconds after releasing the brake pedal, making hill-starting easier.
