Audi lane assist

Audi lane assist
Applies to vehicles: with lane assist
Description
The lane assist system assists the driver in keeping the
vehicle in the right lane.
The system uses a camera to detect the markings of the lane you are
driving in. If the vehicle approaches one of the detected lane mark-
ings, the steering wheel vibrates to warn the driver that the vehicle
might be about to cross one of the markings. The lane assist system
is functional when it has detected lane markings on both sides of
the lane you are driving in. The green lamp
cluster indicates that the function is activated and fully functional.
If you operate the turn signal before crossing one of the lane mark-
ings (while the lane assist system is functional), the system will
detect that the lane change is intended and will not warn the driver.
As the system is designed for driving on motorways and other major
roads, it is only active above a speed of about 65 km/h.
WARNING
The lane assist system does not keep the vehicle in its lane. It
merely warns the driver when the vehicle is in danger of crossing
the markings of the lane. As the driver you are always responsible
for staying in your own lane.
The camera cannot detect all lane markings. Therefore it is
possible that variations in the road surface or objects might be
detected as lane markings, which can lead to false warnings, or
warnings not being given.
The camera's view might be obstructed, for example by vehi-
cles travelling in front, rain, snow, a lot of water on the road or

markings correctly.
