This driving assistance device warns you when you unwittingly cross a lane marking (either a continuous or a dotted line on the road surface). It is designed for use on motorways and dual carriageways, operating only above speeds of approx. 80 km/h (50 mph)..

Activation/Deactivation

A press on button A activates the function, the warning lamp on the button lights up.

A second press on button A deactivates the function, the warning lamp on the button goes out.

When you start the engine, the mode (activated/deactivated) selected when you stopped the engine is retained.

Operation

Above a speed of around 80 km/ h, if you cross a lane marking, you are alerted to this by a vibration within the cushion of your seat:

On the right hand side if you cross a lane marking to the right.

On the left hand side if you cross a lane marking to the left.

The system does not alert you if one of your direction indicators is operating and for approx. 20 seconds after the direction indicator has stopped.

Remarks:

This system is designed to identify traffic lane markings.

In certain cases it may trigger an alert that is unnecessary, for example if the vehicle passes over a directional arrow or some unusual road marking.

The system may be affected temporarily by conditions external to the vehicle:

Detection of lane markings made difficult by:

Markings being worn.

Insufficient contrast with the general road surface.

Sensors being negated by:

Driving in snow or heavy rain.

Driving on roads that are covered with mud or water puddles.

If there is prolonged interference, contact a CITROËN dealer.

The driver still has to remain attentive and in complete control of his vehicle.
