The assist systems analyze the data from various sensors and cameras installed in the vehicle. Do not use any assist systems if there is damage in there area of the sensors and cameras or on the vehicle underbody. Damage can impair the function of the sensors and cameras or cause malfunctions.

Have an authorized Audi dealer or authorized Audi Service Facility check their function.

Radar sensors

Depending on the vehicle equipment, the area in front of and behind the vehicle may be detected fig. 88 1.

The wheel sensors on the rear corners of the vehicle are positioned so that the adjacent lanes to the left and right are detected on roads with a normal lane width.

Ultrasonic sensors

Depending on vehicle equipment, various areas may be displayed in the MMI using the ultrasonic sensors fig. 88.

The range of the displays depends on the location of the ultrasonic sensors:

  1. Approximately 4 feet (1.20 m)
  2. Approximately 3 feet (0.90 m)
  3. Approximately 5.2 feet (1.60 m)
  4. Approximately 3 feet (0.90 m)
  5. Approximately 3 feet (0.90 m)

The side area 6 is detected and evaluated when passing. There may have been changes to the surrounding area after switching the ignition off and on again, after opening the doors, or if the vehicle is left stationary for a period of time. In this case, the area will appear black until the area has been detected and evaluated.


Use the camera image on the display to assist you only if it shows a good, clear picture. Keep in mind that the image in the display is enlarged and distorted. Under certain circumstances, objects may appear different and unclear on the display.

The rearview camera can only detect the area marked in red fig. 89. Only this area is displayed on the center display.


  • Sensors and cameras have spots in which the surrounding area cannot be detected.

    Objects, animals, and people may only be detected with limitations may not be detected at all. Always monitor the traffic and the vehicle's surroundings directly and do not become distracted.

  • Sensors may be subject to physical system limitations. External sources of interference, for example from other vehicles, can impair sensor functionality. The assist systems may be limited or may not function as expected.


  • Obstacles may disappear from the measurement range when approaching them, even if they were already detected.
  • In some situations, the ability of the sensors and cameras to detect and display certain objects may be limited.
    • Objects located above the coverage area, such as bumpers on parked cars, garage doors that are partially open, or objects that are hanging
    • Low obstacles
    • Narrow objects, such as barrier chains, foliage, poles, or fences
    • Projecting objects, such as trailer draw bars
    • Objects with certain surfaces and structures, such as fabric


  • The sensors and cameras and the areas around them must not be obstructed because this can impair the function of the systems that depend on them. Make sure that the sensors and cameras are free of snow, ice, and other deposits. Attachments, stickers, adhesive, or similar objects must not extend into the visual field of the sensors and cameras.
  • On vehicles that have factory-installed license plate brackets on the front of the vehicle, the brackets may only be replaced with ones that are the same size and made of the same material. Do not install any license plate brackets on the front of vehicles that do not have factory-installed brackets.

    Otherwise, the function of the system could be impaired.

  • The function of the sensors and cameras may be limited when light and visibility conditions are poor, for example when driving into a tunnel, when there is glare, or when there are reflective objects.
  • External ultrasonic sensors, such as those in other vehicles, can interfere with the sensors.
  • The coverage areas of the sensors fig. 88 and cameras fig. 89 are diagrams and do not represent a true-to-scale image of the sensor ranges.
  • The system complies with United States FCC regulations and ISED regulations.

Front area

Depending on the vehicle equipment, the following sensors and cameras may be installed:

  • Camera behind the windshield
  • Peripheral cameras on the exterior mirrors
  • Front peripheral camera in the radiator grille
  • Front and side ultrasonic sensors
  • Front radar sensor in the center of the radiator grille

Rear area

Depending on the vehicle equipment, the following sensors and cameras may be installed:

  • Rearview camera in the luggage compartment lid
  • Radar sensors at the rear corners of the vehicle
  • Rear and side ultrasonic sensors


  • The locations of the sensors may differ slightly depending on vehicle equipment.
  • Some sensors are installed under vehicle components and cannot be seen from the outside.
  • The system complies with United States FCC regulations and ISED regulations.
