Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
● No operation of turn signals.
● No brake pedal operation.
● No active accelerator operation or speeding-up.
Driving and operating175If the driver is active, no warning will
be issued.
Activation
The lane departure warning system is activated by pressing ½. The system
is switched on when the LED in the
button is not illuminated.
The system is only operable at

176Driving and operatingDriver alert
The driver alert system monitores the driving time and the vigilance of the
driver. Monitoring the vigilance of the
driver is based on the trajectory
variations of the vehicle compared to
the lane markings.
The system includes a driving time alert combined with driver drowsiness detection.9 Warning
The system cannot replace the
need for vigilance on the part of
the driver. It is recommended that
you take a break as soon as you
feel tired or at least every two
hours. Do not take the wheel if you are tired.
Activation or Deactivation
The system can be activated or
deactivated in the vehicle
personalisation 3 103
The state of the system stays in
memory when the ignition is switched
off.
Driving time alert
The driver gets notified by a pop-upreminder symbol € in the Driver
Information Centre simultaneously with a acoustic alert if the driver has
not taken a break after two hours of
driving at a speed above 65 km/h. The
alert is repeated hourly until the
vehicle is stopped, no matter how
vehicle speed evolves.
The counting of driving time alert is
reset when the ignition has been
switched off for a few minutes.
Driver drowsiness detection The system monitors the driver's level
of vigilance. A camera at the top of the
windscreen detects variations in
trajectory compared to the lane
markings. This system is particularly
suited to fast roads (speed higher
than 65 km/h).
If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by the
driver, the system triggers the firstlevel of alert. The driver is notified by
a message and an audible signal is
given.
After three first level alerts, the
system triggers a new alert with a message, 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 driver drowsiness detection is
reinitialised when the ignition has
been switched off for a few minutes or the speed remains below 65 km/h for a few minutes.
System limitations In the following situations, the system
may not operate properly or even not operate at all:
● Poor visibility caused by inadequate lighting of the
