Distraction detection
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
The function comprises the "Coffee Break Alert"
system combined with the "Driver Attention
Warning" system.
These systems are in no way designed to keep the driver awake or to prevent
the driver from falling asleep at the wheel.
It is the driver’s responsibility to stop if feeling
tired.
Take a break if you are feeling tired or at least
every 2 hours.
Activation/Deactivation
By default, the function is automatically activated
at every engine start.
It is configured in the ADAS touch screen
application.
Coffee Break Alert
The system triggers an alert when it detects that the driver has not taken a
break after two hours of driving at a speed above
43 mph (70
km/h).
This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the alert
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following
conditions is met:
–

With the engine running, the vehicle has been
stationary for more than 15 minutes.
–


The ignition has been switched off for a few
minutes.
–


The driver's seat belt is unfastened and their
door is opened.
As soon as the speed of the vehicle drops below 43 mph (70 km/h), the
system goes into standby.
Driving time starts being counted again once
the speed reaches above 43
mph (70 km/h).
Driver Attention Warning

The system assesses the driver's level of alertness, fatigue and distraction by
identifying trajectory changes in relation to the
lane markings.
To do this, the system uses a camera, placed on
the upper part of the windscreen.
This system is particularly suited to fast roads
(speed higher than 43 mph (70
km/h)).
At a first alert level, the driver is warned by
the message "Caution!“, accompanied by an
audible signal.
