Lane departure prevention
Lane departure prevention
Introduction

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 3

- To deactivate the function, if it has previously been deactivated from the "Perso" mode in the "My Safety" function MY SAFETY, press twice on the switch 3. The
warning light appears in yellow on the instrument panel.
- To reactivate the function, press the switch 3 once. The
warning light is displayed on the instrument panel.
Operation

When the function is activated, the
warning light 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 vehicle speed is over approximately 43 mph (70 km/h) and if the
warning light and right-hand or left-hand line indicators 4 are displayed in white.
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 "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.
If 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 indicators, 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 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 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 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 and the indicator 4 on the side of the line concerned flashes 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"
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
warning light displayed in white or grey on the instrument panel. Therefore, the "Lane Centring" function status is given priority in terms of informing you;
- the "Lane centring" function is put on standby and the "Lane departure prevention"
function neither alerts nor intervenes: the grey
warning light replaces the
warning light displayed in white or grey on the instrument panel. Therefore, the "Lane Centring" function status is given priority in terms of informing you;
- 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. Therefore, the "Lane Departure Prevention" function status is given priority in terms of informing you.
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.
Function temporarily unavailable/disabled
The system is temporarily unavailable or disabled when:
- very fast lane departure;
- driving continuously on a line;
- approximately four seconds after changing lanes;
- tight bends;
- impaired visibility;
- one of the direction indicators is activated;
- activating the hazard warning lights;
- engaging reverse gear;
- strong acceleration;
- the lane width changes;
- operation of the Electronic Stability Control system;
- operation of the anti-lock braking system;
- the active emergency braking system is triggered;
- intervention of another function that controls the steering system, such as the "Lane Centring" function.
If the function is unavailable, the
warning light and left-hand and right-hand correction indicators 4 change to grey on the instrument panel.
When the front camera is obscured, the "Front camera no visibility" message is displayed on the instrument panel. Clean the area where the sensors are
located
Automatic deactivation
The function is automatically deactivated when:
- the vehicle dynamics control system is deactivated;
- the electronic stability system is malfunctioning;
- the anti-lock braking system is malfunctioning;
- a towbar is electrically connected to the trailer hitch socket;
- the
warning light appears.
When the function is deactivated, the
warning light is displayed in yellow on the instrument panel.

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 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.
