Emergency lane departure prevention

Using information from the radar 2 and the camera 1, the function triggers corrective action on the vehicle steering system in the event of a risk of collision with a vehicle coming from the opposite direction in the adjacent lane, without the direction indicator having been activated.
Depending on the vehicle, using information from the radars 3 and the camera 1, the function triggers corrective action on the vehicle steering system in the event of a risk of collision with a vehicle moving at the same speed or at a higher speed, if within the detection zone of the rear radars (emergency lane departure prevention in case of overtaking).
Tip
You can retake control of the vehicle at any time by operating the steering wheel.
WARNING
This system provides an additional driving aid. This system 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.

Location of the camera 1

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

Location of the front radar 2

Ensure that the radar area is not obstructed (dirt, mud, snow, a badly fitted/attached front number plate), impacted, modified (including paintwork) or hidden by any accessory fitted on the front of the vehicle (on the front bumper, logo, etc.)

Location of the side radars 3

Ensure that the radar area is not obstructed (by dirt, mud, snow etc.), impacted or modified (including paintwork etc.).

Operation

Detection of an oncoming vehicle

When driving at a speed between approximately 43 mph (70 km/h) and 68 mph (110 km/h), if there is a risk of collision with a vehicle coming from the opposite direction in an adjacent lane and within the detection zone A, without the direction indicator having been activated, the system:
  • warns you of a collision risk:
    the "Risk of collision" message appears on the instrument panel accompanied by the warning light in red, a beep and, depending on the equipment, the line on the side concerned and the symbol 10;
    and
  • triggers corrective action on the steering system.
Tip
You can interrupt the trajectory correction at any time by moving 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.
WARNING
The function may not be activated if:
  • the approaching speed is greater than approximately 124 mph (200 km/h) (for example, you are travelling at 68 mph (110 km/h) and the oncoming vehicle is moving in the opposite direction in the adjacent lane at 57 mph (91 km/h).

If case of overtaking

(depending on the vehicle)
When driving (vehicle speed between approximately 43 mph (70 km/h) and 112 mph (180 km/h), if there is a risk of collision with a vehicle located in the blind spot B and it is moving in the same direction as your vehicle or with a vehicle that is rapidly approaching from behind in an adjacent lane that is in the detection zone C, the system:
  • warns you of a collision risk:
    the indicator light 11 flashes, the "Lateral obstacle detected" message is displayed on the instrument panel accompanied by the warning light in red, a beep and, depending on the equipment, the line on the side concerned and the symbol 12;
    and
  • triggers corrective action on the steering system.

Temporary unavailability or inhibition of the system

The system is temporarily unavailable in the following situations:
  • very fast lane departure;
  • driving continuously along a line;
  • during approximately four seconds after changing lanes;
  • tight bends;
  • visibility is impaired;
  • one of the direction indicators are activated (only for detecting an oncoming vehicle moving in the opposite direction in an adjacent lane);
  • activating the hazard warning lights;
  • strong acceleration;
  • the lane width changes;
  • operation of the electronic stability control "ESC";
  • operation of the anti-lock braking system;
  • operation of the active emergency braking system;
  • ...
The system cannot be activated when:
  • the camera does not detect a line (solid or broken) on the relevant side of the vehicle;
  • the camera does not simultaneously detect the two boundaries of the lane in which your vehicle is moving;
  • reverse gear is engaged;
  • the field of vision of the camera is obstructed;
  • the front radar is obscured;
  • the rear radars are obscured, depending on the vehicle.
Depending on the vehicle, if one of the side radars is obscured, the "Side radars no visibility" message will appear on the instrument panel.
When the front radar is obscured, the "Front radar no visibility" message is displayed on the instrument panel.
When the front camera is obscured, the "Front camera no visibility" message appears on the instrument panel.
Clean the area where the sensors are located.

Automatic deactivation

The system is automatically deactivated when:
  • the electronic stability control "ESC" is deactivated or malfunctions;
  • the anti-lock braking system is malfunctioning;
  • a towbar is electrically connected to the trailer hitch socket;
  • the warning light is displayed.
If the vehicle is equipped with a towbar that is recognised by the system, the "Trailer: side radars unavailable" or, depending on the equipment, the "Trailer: side radars OFF" message is displayed to inform you that the "Lane departure prevention" function has been deactivated.
If the vehicle is towing a trailer or caravan, unexpected or unnecessary corrections may occur.
You can deactivate the system to avoid unexpected or unnecessary corrections.

Operating faults

When the system detects an operating fault, the following messages may be displayed on the instrument panel:
  • « Check Front camera » ;
or
  • « Front radar to check » ;
or
  • « Check Driving assist » ;
or, depending on the vehicle,
  • « Check Side radars ».
Consult an approved Dealer.

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 or radars are located (replacements, repairs, 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 "Emergency 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 camera area (on the windscreen side or the interior rear-view mirror side) or radar area(s) have been damaged;
  • the road is slippery (snow, black ice, aquaplaning, gravel etc.);
  • poor visibility (night, fog, etc.);
