A1 (8X) – Enable Hill Start Assist

Function to be activated via VCDS - VAG-COM software

Description of the option:

Activates Audi Hill Start Assist.

The Audi Hill Start Assist is a hill start assistant. If you hold down the brake pedal for a while when the vehicle is stationary, brake pressure is retained for a few seconds after releasing the brake pedal, making it easier to start on a hill.

Attention: Not to be confused with the Audi Hold Assist button which keeps the vehicle stationary uphill and downhill for as long as desired. If the vehicle remains stationary for a long period, the system automatically switches to the electromechanical brake.
