Driving

Using a camera placed at the top of the
windscreen, the system assesses the
driver's level of vigilance, fatigue or distraction by
identifying variations in trajectory compared to
the lane markings.
This system is particularly suited to fast roads
(speed higher than 40 mph (65 km/h)).
At a first-level alert, the driver is warned by the
“ Take care! ” message, accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Dangerous
driving: take a break ", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.
The following situations may interfere
with the operation of the system or
prevent it from working:
– lane markings absent, worn, hidden (snow,
mud) or multiple (roadworks);
– close to the vehicle ahead (lane markings
not detected);
– roads that are narrow, winding, etc.
Lane Departure Warning
System
Refer to the General recommendations on the
use of driving and manoeuvring aids .
This system, using a camera which recognises
solid or broken lines, detects the involuntary
crossing of longitudinal traffic lane markings on
the ground.
If the driver's attention drops and the speed
is higher than 37 mph (60 km/h), the system
triggers a warning if there is an unexpected
change of direction.
This system is particularly useful on motorways
and main roads.
Activation/Deactivation
► Activation/deactivation via this button or the
touch screen, depending on version.
The indicator lamp comes on when the function
is activated.
The state of the system is memorised when the
ignition is switched off.
Detection
If an unexpected change of direction is
detected, this warning lamp flashes in the
instrument panel accompanied by an audible
signal.
No warning is transmitted while the direction
indicator is activated and for approximately 20
seconds after the direction indicator is switched
off.
Malfunction
In the event of a malfunction, this warning
lamp flashes on the instrument panel for
about 10 seconds then goes out.
