Audi A6 Typ 4G: Audi active lane assist

Description

Applies to: vehicles with Audi active lane assist

Active lane assist detects lane marker lines within the limits of the system using a camera in the windshield. If you are approaching 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 lightly. In order for this warning vibration to occur, it must first be switched on in the Infotainment system. Active lane assist is ready for operation when the lane marker line is detected on at least one side of the vehicle.

The system is designed for driving on expressways and highways and therefore only activates at speeds above approximately 40 mph (65 km/ h).

Applies to: vehicles with side assist

If you activate a turn signal when active lane assist is ready and it classifies a lane change as critical because of vehicles traveling alongside you or approaching you, there will be noticeable corrective steering shortly before you leave the lane.

This will attempt to keep your vehicle in the lane.

Applies to: vehicles without side assist

The system will not warn you before crossing a lane marker line if you have activated the turn signal. In this case, it assumes that you are changing lanes intentionally.

Applies to: vehicles with adaptive cruise control

The corrective steering is targeted based on the driving situation. In addition to the lane marker lines, the system can also take into account other objects such as guard rails. If they are detected in close proximity to the vehicle, active lane assist helps prevent the vehicle from driving too close to them. There is also passing assistance. The system does not provide any corrective steering if it detects that you are passing another vehicle.

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. Always keep your hands on the steering wheel.
• Corrective steering may not occur in certain situations, such as during heavy braking.
• There may be cases where the camera does not recognize all lane marker lines. Corrective steering can only take place on the side of the vehicle where lane marker lines are detected.
• Other road structures or objects could possibly be identified unintentionally as lane marker lines. As a result, corrective steering may be unexpected or may not occur.
• The camera view can be restricted, for example by vehicles driving ahead or by rain, snow, heavy spray or light shining into the camera. This can result in active lane assist not detecting the lane marker lines or detecting them incorrectly.
• Under certain conditions such as ruts in the road, a banked roadway or crosswinds, the corrective steering alone may not be enough to keep the vehicle in the middle of the lane.
• For safety reasons, active lane assist must not be used when there are poor road and/ or weather conditions such as slippery roads, fog, gravel, heavy rain, snow and the potential for hydroplaning. Using active lane assist under these conditions may increase the risk of a crash.

Indicator lights

Ready: the indicator light turns on when the system is ready for use. The system can now be operated.

Not ready: the indicator light turns on if the system is switched on but is inoperable. This may be due to the following reasons:

• There is no lane marker line.
• The relevant lane marker lines are not detected (for example, markings in a construction zone or because they are obstructed by snow, dirt, water or lighting).
• The vehicle speed is below the activation speed of approximately 40 mph (65 km/h).
• The lane is too narrow or too wide.
• The curve is too narrow.
• The driver's hands are not on the steering wheel.

Tips

Make sure the camera's field of view fig. 101 is not obstructed by stickers or anything else. For information on cleaning.
