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 de-
activates 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.
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 cush
ion of your
seat :
- oriented to the right for crossing a lane marking to the righ
t,
- oriented to the left for crossing a lane marking to the lef
t.
The system does not alert you while your direction indicator is o
perating,
nor for about 20 seconds after your direction indicator has stopp
ed.
Note : In the event of an electronic malfunction, a message is displ
ayed,
the SERVICE warning lamp comes on and a sound signal is heard. Con-
tact a CITROËN dealer.
Observations : This device is designed to identify traffic lane markings.
In certain specific instances, it may trigger an unwanted alert, for examp
le
when you cross a direction arrow or some other random marking.
The effectiveness of the system may be temporarily affected by condi
tions
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.
