Audi Q8 e-tron hold assist
Hold assist enables convenient drive-offs when the car is on the usual inclines and descents of street traffic, and it prevents the vehicle from rolling.
The system automatically switches over to the electromechanical parking brake when the car is stopped for a longer period of time while hold assist is activated. This ensures that the car will remain stationary even without activation of the parking brake. After a stop at a traffic light, for instance, the car drives off as soon as the driver presses the accelerator pedal. The system is activated in MMI in the following menu.
MMI -> Car - > Setting & Service -> Hold assist -> on/off
Hold assist is standard equipment on Audi Q8 e-tron
