LANE DEPARTURE
WARNING SYSTEM
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 carriageways,
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 deacti-
vates 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.

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:
- 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 exam-
ple 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
erased.
- Insufficient contrast with the sur-
face 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 pro-
longed period, contact a CITROËN
dealer.
The driver must still 
remain attentive and in
complete control of the
vehicle.
