2018 Audi A5 Coupe / S5 Coupe — Owner's Manual
The display brightness adjusts automatically to the brightness of the surroundings, both in the information and in the warning stage. In very dark or very bright surroundings, the automatic adjustment will set the display to the minimum or maximum level. In such cases, you may notice no change when adjusting the brightness, or the change may only be noticeable once the surroundings change. Adjust the brightness to a level where the display in the information stage will not disrupt your view ahead.
If you change the brightness, the display in the exterior mirror will briefly show the brightness level in the information stage. The brightness of the warning stage is linked to the brightness in the information stage and is adjusted along with the information stage. When the vehicle is stationary, the exit warning system warns the passengers of a possible collision when opening the door. Within the limits of the system, the system monitors the areas behind and next to the vehicle using the radar sensors page 134.
Moving objects that are approaching from behind, such as cars, are detected fig. 135. When you open the door, the warning strip on the affected door blinks fig. 136 if another road user is detected and the situation is classified as critical. The display in the exterior mirror on the affected side flashes at the same time. If the door is already open and another road user is detected and the situation is classified as critical, then the corresponding displays turn on.
