Below you find a detailed explanation how each driver assistance functionality works.

  • 360 degree cameras

    The four 360 degree cameras on the vehicle scan the immediate vicinity and display obstacles within. Drivers can choose from different views that simplify parking and maneuvering.

  • Active lane assist

    Operating at speeds from 65 km/h (40.4 mph), Audi active lane assist helps the driver keep the vehicle in the driving lane.

  • Adaptive cruise assist

    The adaptive cruise assist is a combination of adaptive cruise control and active lane assist.

  • Adaptive cruise control with speed limiter.

    The Adaptive cruise control (ACC) supports the driver by using the set within the system limits

  • Collision avoidance assist

    Collision avoidance assist helps the driver steer around an obstacle in a critical situation.

  • Cross traffic assist rear

    Cross traffic assist rear warns the driver of approaching vehicles it deems critical when slowly backing up, such as when pulling out of a perpendicular parking spot.

  • Cruise control

    Cruise control maintains a desired driving speed constantly starting at around 30 km/h (18.6 mph), provided that it can be maintained by engine power and engine braking effects.

  • Curb warning

    The curb warning identifies curbs that pose a risk to the tires or wheels.

  • Emergency assist

    Emergency assist detects, within system limits, when the driver is inactive. In such a case, the system assumes control of the vehicle and automatically brakes it to a standstill in its own lane.

  • Exit warning

    Exit warning improves safety in city traffic. If the car has come to a stop and other vehicles or bicyclists classified as critical are approaching from the rear, the system warns passengers not to open the doors.

  • Hold assist

    Hold assist enables convenient drive-offs when the car is on the usual inclines and descents of street traffic, and it prevents the vehicle from rolling.

  • Parking system plus

    Parking system plus informs the driver, visually and audibly, about obstacles in front of and behind the vehicle.

  • Pre sense basic

    Audi pre sense basic initiates preventive safety measures for occupants as soon as it recognizes a critical driving state.

  • Pre sense front / Pre sense city

    Audi pre sense front and Audi pre sense city utilize the data of radar sensors and/or the front camera, depending on the car model, to compute the probability of a collision. Within the limitations of the system, it warns of collision threats and initiates braking at specific vehicle speeds.

  • Pre sense rear

    Audi pre sense rear uses radar sensors in the rear bumper to detect an impending rear-end collision, and it initiates preventive safety measures.

  • Reversing camera

    The reversing camera simplifies maneuvering by showing the zone behind the vehicle on the MMI display.

  • Side assist

    The Audi side assist lane-changing assistant helps the driver to change lanes at driving speeds of 15 km/h (9.3 mph) and faster.

  • Speed limiter

    The configurable speed limiter limits driving speed to a value set by the driver within the speed range of 30 to 250 km/h (18.6 to 155.3 mph) – which is very helpful within city limits or construction zones, for example.

  • Traffic sign recognition

    Camera-based traffic sign recognition detects traffic signs such as speed limit signs (including digital signs), no passing zones, entry restriction signs and other auxiliary signs, and it shows them to the driver in graphic form.
