Driving
With touch screen
► In the Driving / Vehicle menu, select
the "Vehicle settings" tab, then
"Security" and activate/deactivate "Fatigue
Detection System".
Coffee Break Alert
The system triggers an alert as soon as it
detects that the driver has not taken a
break after two hours of driving at a speed above
40 mph (65 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 40 mph (65 km/h), the
system goes into standby.
The driving time is counted again once the
speed is above 40 mph (65 km/h).

Driver Attention Warning
Depending on version, the "Coffee Break Alert"
system is combined with the "Driver Attention
Warning" system.
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.
