Lane departure warning system
System which detects the involuntary crossing
of longitudinal traffic lane markings on the
ground (solid or broken line).
Sensors, fitted below the front bumper, trigger
a warning if the vehicle drifts over a lane
marking (speed higher than 50 mph (80 km/h)).
This system is particularly useful on motor ways
and main roads.The lane departure warning system
cannot in any circumstances replace
the need for vigilance on the part of the
driver.
It is necessary to observe driving
regulations and take a break every
two
hours.
Deactivation
F Press this button again, the indicator lamp goes off.
The status of the system remains in the
memory when the ignition is switched off. No warning is transmitted while the direction
indicator is active and for approximately
20
seconds after the direction indicator is
switched off.
A warning may be transmitted if a direction
marking (e.g. arrow) or non-standard marking
(e.g. graffiti) is crossed.

- i f the sensors are dirty (mud, snow...),
-

i
f the markings on the ground are

and a message in the screen.
