202 Driving and operating
driver is based on the trajectory
variations of the vehicle compared to
the lane markings.
9 Warning
The system cannot replace the
need for vigilance on the part of
the driver. Taking a break is
recommended as soon as feeling
tired or at least every 2 hours. Do
not take the steering wheel when
feeling tired.
Activation or Deactivation
The system can be activated or
deactivated in the vehicle
personalisation 3 124.
The state of the system stays in
memory when the ignition is switched
off.
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 2 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 if one of the following conditions
is met:
● The vehicle has been stationary
for more than 15 minutes with the
engine running.
● The ignition has been switched
off for a few minutes.
● The driver's seat belt has been
unfastened and the driver's door
is open.
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. 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 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.
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
roadway, falling snow, heavy
rain, dense fog etc.
