Lane Departure Warning System - CITROEN C4 PICASSO Handbook

Driving
Lane departure warning system
System which, using a camera which
recognises solid or broken lines, detects the
involuntary crossing of longitudinal traffic lane
markings on the ground.
To provide safe driving, the camera analyses
the image then, if the driver's attention drops,
triggers a warning if the vehicle drifts over
a lane marking (speed higher than 50 mph
(80 km/h)).
This system is particularly useful on motorways
and main roads.
The lane departure warning system
cannot, in any circumstances, replace
the need for vigilance and responsibility
on the part of the driver.
It is necessary to observe the driving
regulations and to take a break every
two hours.

(at the level of the reel).

indicator is active and for approximately
20 seconds after the direction indicator is
switched off.

In the event of a fault, the symbol
for the button changes to alert
mode and the warning lamp flashes
for a few moments then goes off.
Contact a CITRoËn dealer or a qualified
workshop.
The detection may be impeded:
- if the markings on the ground are
worn,
- if there is little contrast between the
markings on the ground and the
road surface,
- if the windscreen is dirty,
- in certain severe weather
conditions: fog, heavy rain, snow,
bright sunlight or direct exposure
to the sun (low sun, leaving a
tunnel, ...) and shade.
