The Audi A8 hybrid can be optionally equipped with a series of assistance systems that make driving even more relaxing and composed. Audi side assist, whose radar sensors monitor what is happening behind the car, warns the driver of critical lane changes. It is activated upon reaching 30 km/h (18.64 mph).

Audi lane assist, which is active at speeds of about 65 km/h (40.39 mph) and above, uses a camera to observe the lane markings. If the driver approaches one of them without using the turn signal, there is an adjustable vibration at the steering wheel. The speed limit display recognizes speed limit signs and presents them on the display of the driver information system and on the MMI monitor. The parking system plus with surround view camera makes parking easier.

Four small cameras monitor the surroundings of the car. A computer combines their images and displays them in a variety of views.

The night vision assistant with highlighting of detected persons uses a far infrared camera that reacts to radiated heat. It displays the information it collects as black-and-white images on the display of the driver information system. The cooler surroundings appear dark, while people and animals are conspicuously bright. The system, which has a visual range of up to 300 meters (984.25 ft), can detect people at up to 100 meters (328.08 ft) away and highlights them with yellow markings. In a hazardous situation, they are marked red and a warning gong sounds.

A standard feature in the A8 hybrid is the safety system pre sense basic. If the ESC sensors report a critical state, the control unit activates the hazard warning lights and closes the side windows and the sunroof, depending on the situation; it also tensions the front seat belts and emits a tone to warn the driver.

If Audi side assist is also on board, then there is also the function pre sense rear, which mitigates the consequences of a rear-end collision.
