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.
Activation
F When switching on the ignition
or with the engine running, press
this button to activate the system;
the indicator lamp comes on.
The lane departure warning system
cannot, in any circumstances replace
the need for vigilance on the part of the
driver.
Deactivation
You are warned by the vibration of the driver's
seat cushion:
- on the right-hand side, if the marking on
the ground has been crossed on the right,
- on the left-hand side, if the marking on the
ground has been crossed on the left.
No warning is transmitted while the direction
indicator is active and for approximately
20 seconds after the direction indicator is
switched off.
Detection - Alert
Operating fault
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.
F Press this button again, the
indicator lamp goes off.
In the event of a fault, the indicator lamp in the
button flashes.
Contact a CITROËN dealer or a qualified
workshop.
The status of the system remains in the
memory when the ignition is switched off.
It is necessary to observe the driving
regulations and to take a break every
two hours.
