active
lane assist
Description
Applies
to
vehicles:
with
Audi
active lane
assist
Active lane ass ist detects lane marker lines with-
in the limits of the system using a came ra in the
windshie ld. If you are app roach ing a detected
lane marker line and it appears likely that you
will leave the lane, the system will warn you with
corrective steering
.
You can override this steering
at any time. If you pass over a line, the steering
wheel will vibrate light ly. In order for this warn-
ing vibrat ion
to
occur, it must first be switched
on in the MMI. Active lane assist is operable
when the lane marker line is detected on at least
one side of the veh icle.

The system will not warn you befo re crossing a
lane marker line
if
you have activated the turn
s ignal. In this case, it assumes that you are
changing lanes intentionally.
The system is des igned for driving on express
-
ways and highways and therefore on ly activates
at speeds above approx imately 40 mph (65 km/
h).
A
WARNING
-
-
The system warns the driver that the vehicle
is leaving the lane using corrective steering
.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself. Al-
ways keep you
r
hands on the steering
wheel.
-
Corrective steer ing may not occur in certa in
situa
t
ions, su ch as during heavy braking.
-
There may be cases where the camera does
not recognize all lane ma rker lines. Correc-
tive stee ring can only take place on the side
of the vehicle where lane marker line5 are
detec
t
ed.
-
Othe
r
road structures or obje
ct
s cou ld possi-
b ly be identified un intent ionally as lane
marker lines
.
As a result, corrective steering
may be unexpected or may not occur
.
-
The camera view can be restricted, for
ex-
ample by vehicles driving ahead or by rain,
snow, heavy spray light shining into the
camera or by d irt on the window. This can
result in active lane ass ist not detecting the
lane marker lines or detecting them incor-
rectly.
-
In certain situat ions where visibility is low,
the vehicle may switch from "early" to "late"
corrective steering
l
l.
-
Under certain conditions such as ruts in the
road, an inclined roadway or crosswinds, the
corrective steering a lone may not be enough
to keep the vehicle in the midd le of the lane.
