Lane departure prevention

Using information from the 1 camera, the function triggers corrective action on the vehicle steering system when a continuous or dashed 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 dashed 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.
WARNING
This function is an additional driving aid and the driver is responsible for steering wheel operation. This system is not a substitute for the driver and the driver must drive with his hands on the streering wheel when driving.
Always be careful when driving, as the system may not be unexpectedly deactivated or operated, or may operate unecessarily depending on the road conditions and attention circumstances.

Location of the camera 1

Make sure the windscreen is not obscured (by dirt, mud, snow, condensation etc.).

Activation/deactivation

Activation, deactivation of warnings from button 2 “My Safety”
To deactivate the function, if it has been deactivated from the "custom" mode of the “My Safety Perso” function, press the button 2 twice.
The warning light is displayed in yellow on the instrument panel. To reactivate the function, press the button 2 once. Warning light comes on the instrument panel.
From the multimedia screen 3
To activate or deactivate the function, refer to the multimedia instructions.
Select “ON” or “OFF”.

Operation

When the function is activated, the or warning light and the left and right lines 4 are displayed in grey on the instrument panel.
The function is set to notify or to intervene if the vehicle speed is between approximately 40 mph (65 km/h) and 112 mph (180 km/h) or 99 mph (160 km/h) and if the or warning light and 4 correction indicators are coloured 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 dashed line without activating the direction indicators, if the "dashed lines intervention" setting is selected.
In these cases:
  • the function triggers an action on the vehicle's steering system to correct the vehicle trajectory;
  • warning light or and the indicator 4 on the side of the breached line turns to yellow on the instrument panel.
If corrective action taken on the steering system is not sufficient, the warning light or and the indicator 4 on the side of the breached side line are shown in red on the instrument panel, accompanied by a vibration on the steering wheel.
When the "Dashed lines intervention" setting is not selected, the function sounds the alarm if the vehicle crosses a dashed 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
  • warning light or 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

When using the system :
  • If the system can no longer detect any action by the driver on the steering wheel, the warning light appears in orange on the instrument panel, accompanied by the message “Keep hands on steering wheel” and an audible warning.
Tip
You can interrupt the trajectory correction at any time by moving the steering wheel.
  • if the system is active for too long, an audible warning is emitted and the indicator 3 on the side of the line concerned flashes until the driver takes control.
WARNING
Please note that the system warning may appear late according to road conditions when driver’s hands are off the steering wheel.
Always have your hands on the steering wheel when driving.
The system may warn driver that driver is not holding the steering wheel when the driver operates steering wheel excessively or holds on the steering wheel softly.
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 operating: the warning light or in green replaces the warning light or in white or grey 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 sounding an alarm nor operating: the warning light or in grey replaces the warning light or in white or grey 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 sounding an alarm or operating: the warning light or appears in red or 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.
Temporary unavailability / function 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;
