Fig. 177 Windscreen: lane departure warning system camera window
First read and observe the introductory information
and safety warnings Using a camera in the windscreen, the lane departure warning system (Lane Assist) detects lines on the road that may mark the lane boundary. If your vehicle approaches a recognised marking line unintentionally, the system will warn the driver with a corrective steering intervention. The corrective steering intervention can be overridden by the driver at any time.
When adaptive lane guidance is active   , Lane Assist does not just provide assistance when the vehicle is at risk of leaving the lane. The function provides continuous assistance while driving if the lane is demarcated by 2 markings to the left and right of the vehicle.
The system adopts the preferred position within the lane in which the vehicle is travelling. For example, if the vehicle is being driven slightly off-centre in the lane, the system will learn to adopt the new position within a short period of time.
No steering intervention will occur if the turn signal is switched on as Lane Assist will assume that the lane change is deliberate.
Steering wheel vibration
The following (very rare) situations will cause the steering wheel to vibrate and demand active steering intervention by the driver:
Activating or deactivating Lane Assist
Automatic switch-off: Lane Assist can switch itself off automatically if there is a system fault. The indicator lamp goes out.
Activating or deactivating adaptive lane guidance
Adaptive lane guidance can be activated or deactivated using the
button and the
and
Driver assistance function buttons in the infotainment system   .
Lane Assist is not active (the indicator lamp lights up yellow)
Before starting a journey, check that the camera window is not covered  .
The camera window must be kept clean at all times.
