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.
Location of the camera 1
Make sure the windscreen is not obscured (by dirt, mud, snow, condensation etc.).
Tip
You can retake control of the vehicle at any time by operating the steering wheel.
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.

Operation

When the function is activated, the warning light is displayed in grey and, depending on the equipment, the left-hand and right-hand line indicators 8 are displayed in grey on the instrument panel.
The function is set to notify or react if:
  • the vehicle speed is between approximately 43 mph (70 km/h) and 106 mph (170 km/h);
    and
  • the warning light is displayed in white and, depending on the equipment, the left-hand or right-hand line indicators 8 are displayed in white on the instrument panel.
The function is in operation if the vehicle:
  • approaches a roadside without activating the direction indicators;
  • crosses a continuous line without activating the direction indicators;
  • crosses a broken line without activating the direction indicators, if the "Dashed line intervention" 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 in white or, depending on the vehicle, the warning light and the indicator 8 on the side of the breached line appear in yellow on the instrument panel.
If the corrective action taken on the steering system is not sufficient, the warning light will continue to flash in white or, depending on the vehicle, the warning light and the indicator 8 on the side of the breached line change to red on the instrument panel. This is accompanied by a vibration on the steering wheel.
If the "Dashed line intervention" setting is not selected, the function sounds the alarm if the vehicle crosses a broken line without activating the direction 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 flashes in white or, depending on the equipment, the warning light and the indicator 8 on the side of the breached line change 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 in operation 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 red 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 red accompanied by the indicator 8 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 equipped with "Active Driver Assist" or "Motorway and Traffic Assistant"
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. Therefore, you will be informed first and foremost of the "Lane Centring" function status;
  • 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. Therefore, you will be informed first and foremost of the "Lane Centring" function status;
  • the "Lane Centring" function is put on standby while the "Lane departure prevention" function is in operation or ready: the warning light is displayed in red or in yellow on the instrument panel. Therefore, you will be informed first and foremost of the "Lane departure prevention" function status.
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.

Warnings

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.
System servicing/repairs
  • In the event of an impact, the alignment of the camera or radar(s) may be altered 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.
Only an authorised dealer is qualified to service the system.
In the event of system disturbance
Some conditions can disturb or damage the system's operation, such as:
  • windscreen obscured (by dirt, ice, snow, condensation etc.);
  • a complex environment (tunnel, etc.);
  • poor weather conditions (snow, rain, hail, black ice, etc.);
  • poor visibility (night, fog, etc.);
  • the road markings are irregular or difficult to distinguish (e.g. partially erased, excessive spacing, distorted road surface...);
  • being dazzled (glaring sun, lights of vehicles travelling in the opposite direction; etc.);
  • the road is narrow, winding or undulating (tight bends, etc.);
  • closely following a vehicle travelling in the same lane.
In this case, the "Lane departure prevention" function may be incorrectly triggered or not triggered at all.
Risk of unwanted, incorrect correction or no correction of trajectory.
Deactivating the function
You must deactivate the function if:
  • the area of the camera has been damaged (on the windscreen side or the interior rear-view mirror side);
