Applies to vehicles: with Audi side assist
If side assist switches off by itself, the LED in the button turns off and a message will appear in the instrument cluster display:
Audi side assist unavailable: Sensors blocked
The radar sensors' vision is affected. Do not cover the area in front of the sensors with bike wheels, stickers, dirt or other objects. Clean the area in front of the sensors, if necessary > fig. 130.
Audi side assist: Currently unavailable
Side assist cannot be switched on temporarily because there is a malfunction (for example, the battery charge level may be too low).
Audi side assist: System fault!
The system cannot guarantee that it will detect vehicles correctly and it is switched off. The sensors have been displaced or are faulty. Have the system checked by an authorized Audi dealer or authorized Audi Service Facility soon.
Audi side assist: Unavailable when towing
Side assist switches off automatically when a factory- installed trailer hitch is connected to the electrical connector on the trailer. There is no guarantee the system will switch off when using a retrofitted trailer hitch. Do not use side assist when towing a trailer.
