When the system is deactivated 2
may illuminate in the Driver
Information Centre.
The system is automatically activated
when ignition is switched on.
Driving time alert
The driver gets notified by a pop-up
reminder symbol Y in the Driver
Information Centre simultaneously
with an 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 or the
driver's seat belt has been
unfastened and the driver's door has
been opened.
Note
If the vehicle speed drops below
65 km/h, the system is paused. The
driving time is counted again once
the speed is above 65 km/h.
Driver drowsiness detection
The system monitors the driver's level
of vigilance at speeds above
65 km/h. A camera at the top of the
windscreen detects variations in
trajectory compared to the lane
markings.
The system may perform a learning
procedure for up to 30 minutes after
the start of the monitoring. During this
period, the driver's individual driving
behaviour is analysed and no alert is
given.
If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by the
driver, the system triggers the first
level 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.
Driving and operating
In certain driving conditions such as
poor road surface or strong winds
etc., the system may give alerts
independent of the driver's level of
vigilance.
The driver drowsiness detection is
reinitialised in the following situations:
● the ignition has been switched off
for a few minutes
● the speed remains below
65 km/h for a few minutes
● the driver's seat belt has been
unfastened and the driver's door
has been opened
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
roadway, falling snow, heavy
rain, dense fog etc.
● dazzle caused by headlamps of
oncoming vehicles, low sun,
reflections on damp roads,
leaving a tunnel, alternating
shade and light etc.
