Once it detects that the vehicle is stopped, Audi hold assist keeps the vehicle stationary. The green symbol in the instrument cluster indicates that the function is activated. You can now take your foot off the brake pedal.

As soon as you drive off in the normal way, the parking brake will automatically be released and the vehicle will start moving.

If the conditions for Audi hold assist change and the function is switched off as a result, the parking brake will be applied automatically to ensure that the vehicle is parked safely. The diode in the button will go out when the Audi hold assist function is switched off.
