7.1 Lane Assist, General Information
Lane assist helps the driver keep the vehicle in its lane. If the
system is in operation and the vehicle approaches a recognized
boundary line and will leave the lane, the driver is notified by a
vibration in the steering wheel. If the system is in operation and
the turn signal is activated before driving over a recognized boun‐
dary, the warning is not given because the system assumes it is
an intentional lane change.
The steering wheel is equipped with a vibration motor to create
the steering wheel vibration. The vibration motor is encased in
foam in the lower right spoke of the steering wheel. The steering
wheel vibrations are generated by a rotating weight installed on
the motor. It cannot be replaced separately. The entire steering
wheel must be replaced if the vibration motor is faulty, refer to
⇒ page 282 . The duration of the steering wheel vibration de‐
pends on the driver reaction and generally lasts about one sec‐
ond.
The camera and Directional Stabilization Assistance Control
Module - J759- are installed in one housing. The entire unit must
be replaced if the camera or control module is faulty.
The Directional Stabilization Assistance Control Module - J759-
is installed at the center of the top edge of the windshield at the
level of the interior rearview mirror. It is secured in a bracket that
is bonded to the windshield.
Changes that restrict the visual area of the camera (such as ap‐
plying labels or stone damage) can lead to malfunctions.
The button for the Directional Stabilization Assistance Button -
E517- is integrated in the turn signal lever. Pressing the button
switches the system on and off. The entire turn signal lever with
the button must be replaced if the Directional Stabilization Assis‐
tance Button - E517- is faulty. ⇒ Rep. Gr. 94
Note
The message “Audi lane assist not available: no sensor range at
this time” appears if the camera function is no longer available
due to ongoing poor visibility of the lane lines. It may be due to
the following causes.
♦ The camera visual field is dirty or icy. If that is the problem, it
should be corrected.
♦ There is condensation on the camera visual field. If this is the
case, wait until the condensation disappears.
♦ Lane lines are not visible for an extended period of time due
to road conditions (such as snow on the road surface).
If the condensation does not clear on its own or if there is heavy
dirt on the inside of the lens (in the camera visual field), the cam‐
era visual field must be cleaned by hand. To do this, remove the
control module and the lens screen and clean the front window
using Cleaning Solution . Control Module and Lens Screen, Re‐
