Lane Keeping Assist

Fig. 108: Camera on interior mirror

The lane keeping assist system initiates corrective steering intervention to bring the vehicle back into the lane when it detects that the driver is inadvertently straying from the lane or is changing lanes without indicating. The system also alerts the driver by issuing an acoustic and visual warning. The driver can override the corrective steering intervention at any time.

A camera on the windshield (Fig. 108) is used to view the lane markings in order to continuously recalculate the road ahead.

If the system assesses the distance from the lane lines as critical at a speed of over approx. 40 mph (65 km/h), it initiates corrective steering intervention and the vehicle is guided back into the lane. In addition, a warning tone sounds when the vehicle drives over the lane marking and the lane line in question is identified on the multifunction display.

Exceptions for lane keeping assist
Lane keeping assist is not available in the following situations, for example:

  1. When the turn signal is on.
  2. During PSM intervention and when PSM is off.
  3. If the bend radius is too small (less than approx. 1000 ft. (300 m)) during cornering.
  4. If there is too much braking pressure.
  5. If no steering movement is detected continuously.
  6. At speeds of less than approx. 37 mph (60 km/h).
  7. If lane lines are covered, unclear or missing.
  8. If the camera is very dirty, icy or covered (e.g. with stickers).
  9. In adverse weather conditions (e.g. heavy rain, when the sun is low).

Lack of attention
The driver remains responsible at all times when driving, e.g. staying in lane, even if lane keeping assist is on. The system does not replace the driver's attentiveness.

  • Particular attentiveness is required while driving.
  • Always pay attention to the traffic conditions and the vehicle surroundings.
  • Adjust the speed to road conditions.

Failure of camera to detect the lane
The camera's view can be reduced by different influencing factors (e.g. rain, snow, ice, heavy water spray and backlight). Sometimes, the camera cannot detect the lane lines, or cannot detect them correctly. When this happens, no steering intervention or an unexpected steering intervention can occur.

  • Particular attentiveness is required while driving.
  • Keep the direction of travel and the lane lines in view at all times.
  • Do not obscure the area of the camera on the rear-view mirror (Fig. 108) with foreign bodies (e.g. stickers).
  • The camera must always be kept free of dirt, ice and snow to ensure that it can work properly.
  1. Please see chapter "Car Care" on page 76.

No corrective steering intervention in tight bends
On tight bends, corrective steering intervention is not enough to keep the vehicle in the lane. Lane keeping assist is deactivated and there is no corrective steering intervention.

  • Particular attentiveness is required while driving.
  • Always hold the steering wheel with both hands.
