Lane departure prevention

Using information from the camera 1, the function triggers corrective action on the vehicle steering system when a solid or broken line is crossed or when approaching the roadside (divider, barrier, pavement, embankment, etc.) without the direction indicator lights being activated.
Depending on the setting, in the event of crossing a broken line without activating the direction indicator lights, the function:
  • warns the driver without corrective action on the steering system;
or
  • performs corrective action on the steering system.
Tip
You can retake control of the vehicle at any time by operating the steering wheel.

The function is set to notify or react if:
  • speed is between approximately 40 mph (65 km/h) and 106 mph (170 km/h);
and
  • the warning light or, depending on the vehicle, the left-hand and right-hand line indicators 9 and the warning light appear in white on the instrument panel.
The function is activated if the direction indicators are deactivated and the vehicle:
  • approaches a roadside;
  • crosses a solid line;
  • crosses a broken line if the "Operation on broken line" setting is selected.
In these cases:
  • the function triggers an action on the vehicle's steering system to correct the vehicle trajectory;
and
  • the  warning light flashes or, depending on the vehicle, the indicator 9 on the side of the crossed line and the  warning light appear in yellow on the instrument panel.
If the corrective action taken on the steering system is not sufficient, the warning light continues to flash or, depending on the vehicle, the warning light and the indicator 9 on the side of the crossed line change to red on the instrument panel. This is accompanied by a vibration on the steering wheel.
When the "Operation on broken line" setting is not selected, the function sounds the alarm if the vehicle crosses a broken line without activating the direction lights, and there is no roadside close enough to the line.
In this case, the function warns the driver:
  • by a vibration in the steering wheel;
and
  • the warning light flashes in white or, depending on the vehicle, the warning light and the indicator 9 on the side of the crossed line change to red on the instrument panel.
