64 Assistance systems
You sit at the wheel.
Others are working in the background.
Most road accidents are caused by human error.
Modern assistance systems can help to reduce
their severity. Audi puts various different technologies
to work to help you reach your destination
safely. The assistance systems are closely networked,
which increases their versatility and performance.
With the help of these systems, your
journey will be safer and more relaxed.
On request, the A3 models can be equipped with
something quite special, a sort of sixth sense –
or Audi pre sense. A vehicle sensor categorises
driving situations and initiates any necessary preventive
passenger protection measures at critical
moments, even as far as collision avoidance. The
optional Audi pre sense basic includes various preventive
passenger protection systems that are ac-
adaptive cruise control including automatic full braking
action:* The automatic distance control detects vehicles
ahead by means of a radar sensor. Within system limits, the
vehicle brakes and accelerates automatically, keeping a
constant distance to the traffic ahead. If a collision threatens
– for example in stop-and-go traffic or there is a danger of a
traffic jam – adaptive cruise control can even bring your A3
model to a complete standstill at speeds under 30 km/h.
tivated in the event of a critical driving situation.
These include tensioning of the front seat belts as
well as closing of the windows and – if fitted – the
panoramic glass sunroof. Audi pre sense front additionally
monitors the traffic ahead via the radar
sensor of the optional adaptive cruise control. The
driver is warned of critical situations and the brake
force is increased or, if the driver does not react, a
braking action is initiated by the system.
To avoid critical situations to start with, the optional
attention assist evaluates the driver’s steering
movements and pedal actuation, for example,
at speeds of between 65 and 200 km/h. If these
indicate decreasing driver attentiveness, the system
recommends a break through a display in the
driver information system and an acoustic signal.

In the event of a collision, many safety features
are coordinated in the Audi A3, A3 Sportback and
S3. The engine and fuel supply are stopped, the
door locking mechanism is opened and the hazard
lights and interior lighting are activated. What is
more, the secondary collision brake assist prevents
many instances of uncontrolled continued vehicle
motion. Further safety functions include the highstrength
passenger cell and the load-reducing
design of the interior near the occupants.
Audi active lane assist* with lane centre guide supports you when travelling at speeds of around 60 km/h or above up to a
maximum speed of 250 km/h by a gentle corrective steering movement and warns you through steering wheel vibration if
you leave your chosen lane unintentionally. In the MMI, you have the choice between 2 system settings (steering time early
[A] or late [B]). The camera-based traffic sign recognition is an optional additional function. This displays traffic signs
showing a speed limit or overtaking ban clearly via the driver information system with colour display.
