Audi A1 (8X) – Activate Hill Start Assist (Coding)
Purpose: Allows you to activate the Audi Hill Start Assist.
Warning: Not to be confused with the Audi Hold Assist which allows the vehicle to be held stationary on hills and descents for as long as desired. If the vehicle remains stationary for a long time the system automatically switches to the electromechanical brake. The 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 certain period of time when the vehicle is stationary, the brake pressure is retained for a few seconds after releasing the brake pedal, making hill starts easier.
