Lane Departure Warning System - CITROEN Grand C4 PICASSO Owner's Handbook Manual

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.
Activation / deactivation
Activation and deactivation of the function is
done in the " Driving assistance " menu of the
touch screen tablet.
Press this button, the indicator lamp
comes on. The function is activated
Press this button again, the
indicator lamp goes off. The
function is deactivated
The status of the system remains in the
memory when the ignition is switched off.
Detection - alert
The driver is alerted by vibration of the seat belt
(at the level of the reel):
No warning is transmitted while the direction
indicator is active and for approximately
20 seconds after the direction indicator is
switched off.
Operating fault
In the event of a fault, this warning
lamp comes on accompanied by an
audible signal and a message.
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.
