WARNING  
Observe the safety warnings  
trol and warning lamps on page 123.  
Using the camera located in the windscreen,  
the Lane Assist system detects the possible  
lines dividing the lanes. When the vehicle in-  
voluntarily approaches a dividing line it has  
detected, the system notifies the driver with a  
corrective steering movement. The purpose is  
not only to warn the driver, but also to keep  
the vehicle inside the lane. This movement  
can be over-regulated at any time.
