L A N E D E PA R T U R E W A R N I N G S Y S T E M  
Operation  
Provided you are travelling at over 80 km/h (approx. 50 mph), if you cross  
a lane marking, you are alerted by a vibration within the cushion of your  
seat:  
II  
- oriented to the right for crossing a lane marking to the right,  
- oriented to the left for crossing a lane marking to the left.  
The system does not alert you while your direction indicator is operating,  
nor for about 20 seconds after your direction indicator has stopped.  
Note: This device is designed to identify traffic lane markings.  
In certain specific instances, it may trigger an unwanted alert, for example  
when you cross a direction arrow or some other random marking.

The effectiveness of the system may be temporarily affected by conditions  
external to the vehicle:  
• Detection of lanes made difficult by:  
- Markings that are worn or erased.  
- Insufficient contrast with the surface of the road.  
• Masking of the sensors due to:  
- Driving in snow or heavy rain.  
- Driving on roads covered with mud or surface water.  
If the system is ineffective for a prolonged period, contact a CITROËN  
dealer.  
This driving assistance device  
alerts you if you are wandering  
from your lane (continuous or  
dotted line marking on the road  
surface).  
It is designed especially for use  
on motorways and dual carriage-  
ways, operating only at speeds  
above 80 km/h (approx. 50 mph).  
Activation / Deactivation  
A press on control A activates the  
function, the warning lamp on the  
control lights up.  
A second press on control A deac-  
tivates the function, the warning  
lamp on the control goes out.  
Whenever you start the engine,  
the mode (activated/deactivated),  
selected when you last switched  
off the engine, is retained.  
The driver must still remain attentive and in complete control of  
the vehicle.
