Lane departure prevention

Using information from the 1 camera, the function triggers corrective action on the vehicle steering system when a continuous or broken line is crossed or when approaching the roadside (divider, barrier, pavement, embankment, etc.) without activating the direction indicator lights.
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.

Location of the camera 1

Make sure the windscreen is not obscured (by dirt, mud, snow, condensation etc.).
WARNING
This function is an additional driving aid. This function is not under any circumstances intended to replace the due care and attention of the driver, who should at all times be in control of the vehicle.

Activation/deactivation

From the multimedia screen 2

Please refer to the multimedia instructions for more information.

Using the switch "My Safety"3

  • To deactivate the function, if this has been deactivated from the Custom mode of the "My Safety" MY SAFETY function, press twice on the switch 3. The warning light is displayed in yellow on the instrument panel.
  • To reactivate the function, press the 3switch once. Warning light comes on the instrument panel.

Operation

When the function is activated, the and the left-hand and right-hand line indicators 4 are displayed in grey on the instrument panel.
The function is ready to alert or intervene if the speed is above approximately 40 mph (65 km/h) and if the warning light and the left-hand or right-hand line indicators 5 appear in white.
The function is in operation if the vehicle
  • approaches a roadside without activating direction indicators;
  • crosses a continuous line without activating the indicator lights;
  • crosses a broken line without activating the direction indicators, 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;
  • the warning light and the indicator 4 on the side of the breached line changes to yellow on the instrument panel.
If the corrective action on the steering system is not sufficient, the warning light and the indicator 4 on the side of the breached line change to red on the instrument panel, 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 indicator 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 and the indicator 4 on the side of the breached line turns to red on the instrument panel.
Note: on bends, the function allows for slightly cutting the bend.

Special cases

"Keep control" Warning
  • If the system is operating and does not detect any activity on the steering wheel, the "Keep control" message appears on the instrument panel accompanied by a beep and, depending on the vehicle, the warning light appears in yellow until the driver has regained control of the vehicle.
  • If the system has been in operation for too long, the "Keep control" message appears on the instrument panel accompanied by a beep and depending on the vehicle, the warning light appears in yellow accompanied by the indicator 4 on the side of the line concerned until the driver has regained control of the vehicle.
Tip
You can interrupt the trajectory correction at any time by moving the steering wheel.

Vehicle fitted with "Active driver assist"

If the "Lane centring" function is activated at the same time as the "Lane departure prevention" function, the display of the warning light will vary as follows:
  • the "Lane Centring" function is in operation: the green warning light replaces the white or grey warning light on the instrument panel. Thus, you are informed as a priority of the status of the function "Channel centriing";
  • the "Lane Centring" function is put on standby and the "Lane Departure Prevention" function is neither ready nor in operation: the grey warning light replaces the white or grey warning light on the instrument panel. Thus, you are informed as a priority of the status of the function "Channel centriing";
  • the "Lane Centring" function is put on standby while the "Lane Departure Prevention" function is ready or in operation: the warning light is displayed in red or in yellow on the instrument panel. Thus, you are informed as a priority of the status of the function "Lane departure prevention".
In any case, you are informed at all times of the status of the function when it controls the steering system of your vehicle. The most useful information is always displayed.

System servicing/repairs
  • In the event of an impact, the camera alignment may be changed, and its operation may consequently be affected. Deactivate the function and consult an authorised dealer.
  • Any work in the area where the camera is located (repairs, replacements, windscreen modifications etc.) must be carried out by a qualified professional.
