Driver assist systems
Audi active Lane assist
(Lane departure warning
feature)
Description
Applies to: vehicles with Audi active lane assist
The active lane assist uses a camera in the wind
screen to detect lane markings (subject to gener
al system limitations). If you approach one of the
detected lane markings, the system corrects the
steering to warn you that the vehicle might be
about to cross one of the markings. You can over
ride this steering input at any time. The steering
wheel vibrates slightly if you cross a lane mark
ing. The vibration warning must be activated be
forehand on the infotainment system. The active
lane assist is functional when it detects a demar
cation line on at least one side of the lane in
which you are driving.
As the system is designed for driving on motor
ways and other major roads, it is only active
above a speed of about 65 km/h (may vary in dif
ferent export markets).
Applies to vehicles with side assist*: If you oper
ate the turn signals while the active lane assist
and side assist are active, the steering will be cor
rected just before you cross the lane demarcation
if the side assist detects vehicles approaching
quickly or travelling at about the same speed as
your own vehicle and judges the situation to be
critical. This intervention is intended to keep the
vehicle in the lane.
Applies to vehicles without side assist*: The sys
tem does not warn you if you operate the turn
signal before crossing a lane demarcation. In this
case, it assumes that you intend to change lanes.
A
WARNING
- The system initiates a corrective steering in
put to warn the driver that the vehicle is
about to leave the lane. As the driver you
are always responsible for staying in your
own lane.
ll The steering input function is not available on all export
versions.
92
- The system can assist you to keep the vehi
cle in the lane, however it is not capable of
driving on its own. Never take your hands
off the steering wheel.
- In certain situations, e.g. during heavy brak
ing, the system may not correct the steer
ing.
- In certain circumstances, not all of the lane
markings may be detected by the camera. A
corrective steering input can only be initi
ated if the system detects a lane marking on
the side in question.
- Variations in the road surface or objects on
the road may be misinterpreted as lane
markings. In this case, the steering may be
corrected unexpectedly or not at all.
- The camera's view might be obstructed, for
example by vehicles travelling in front, rain,
snow, a lot of water on the road, adverse
light or dirt on the windscreen. If this hap
pens, the active lane assist may not detect
the lane markings or may respond incorrect
ly.
- In certain circumstances, for instance if visi
bility is poor, the setting for the steering in
put may be switched internally from "early"
to"late" l)_
- In certain driving conditions, such as ruts in
the road surface, adverse cambers or side
winds, the assistance provided by the steer
ing correction may be insufficient to keep
the vehicle in the middle of the lane.
- For safety reasons, the active lane assist
must not be used in poor weather or in diffi
cult or slippery road conditions (such as ice,
fog, loose grit or gravel, heavy rain, snow,
etc.) - risk of accident!
