Assist systems
General information
—As the driver, you are always completely responsible for all driving tasks. The assist systems cannot replace the driver's attention. Give your full attention to driving the vehicle, and be ready to intervene in the traffic situation at all times.
— Activate the assist systems only if the surrounding conditions permit it. Always adapt your driving style to the current visual, weather, road, and traffic conditions.
— Loose objects can be thrown around the vehicle interior during sudden driving or braking maneuvers, which increases the risk of an accident. Store objects securely while driving.
—For the assist systems to be able to react correctly, the function of the sensors and cameras must not be restricted. Note the information on sensors and cameras 2 page 113.
Pay attention to applicable local regulations relating to driving tasks, leaving space for emergency vehicles, vehicle distance, speed, parking location, wheel placement, etc. The driver is always responsible for following the laws that are applicable in the location where the vehicle is being operated.
=You can cancel a steering or braking intervention by the system by braking or accelerating noticeably, steering, or deactivating the respective assist system.
— Always check the assist systems settings before driving. The settings may have been changed, for example by switching off the ignition or by other drivers.
System limitations
~The use of an assist system cannot overcome the natural laws of physics. A collision cannot be prevented in certain circumstances.
— Warnings, messages, or indicator lights may not be displayed or initiated on time or correctly, for example, if vehicles are approaching very fast.
— Corrective interventions by the assist systems, such as steering or braking interventions, may not be sufficient or they may not occur. Always be ready to intervene.
— Due to the system limitations when detecting the surrounding area, the systems may warn or intervene unexpectedly or too late in certain situations. The assist systems may also interpret a driving maneuver incorrectly and then warn the driver unexpectedly.
—The systems may not function as expected in unusual driving situations, such as driving offroad, on unpaved roads, on loose ground, on inclines, or on grooves in the road.
~The systems may not function correctly in unclear traffic situations, such as turning lanes, exit ramps, construction zones, rises or dips that obstruct visibility, intersections, toll stations, or city traffic.
~The detection of the surrounding area can be limited, for example by vehicles driving ahead or by rain, snow, heavy spray, or light shining into the camera.
~The steering wheel touch recognition may be limited when you wear gloves. Steering intervention requests from the steering assist systems may occur more frequently.
— If accessories have been mounted on the steering wheel, the steering assist systems may be limited. The frequency of steering intervention requests from the steering assist systems may vary as well.

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. 75@.
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. 75. The range of the displays depends on the location of the ultrasonic sensors: @ Approximately 4 feet (1.20 m) Approximately 3 feet (0.90 m) @ Approximately 5.2 feet (1.60 m) Approximately 3 feet (0.90 m) Approximately 3 feet (0.90 m) The side area 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. Cameras
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. 76. Only this area is displayed on the center display > A\.
— 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
Assist systems
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 cense 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. 75 and cameras fig. 76 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 page 288.

= 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.
