Driving -> Fatigue detection system for Your Citroen C4 Cactus SUV First Generation (2014-2018)

Driving  
Clean the windscreen regularly,  
Fatigue detection system  
particularly the area in front of the camera.  
The internal surface of the windscreen can  
also become misted around the camera.  
In humid and cold weather, demist the  
windscreen regularly.  
Take a break as soon as you feel tired or at  
least every two hours.  
The function has the "Driving time warning"  
combined with the "Driver inattention alert".  
This alert is issued via the display of a  
message encouraging you 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.  
Do not allow snow to accumulate on the  
bonnet or roof of the vehicle as this could  
conceal the detection camera.  
The system cannot in any circumstances  
replace the need for vigilance on the part  
of the driver.  
Do not take the wheel if you are tired.  
The system resets itself if one of the following  
conditions is met:  
The system is automatically deactivated  
after the use of the "space-saver" type  
spare wheel is detected, or if a fault with  
the side brake lamps is detected.  
Activation/Deactivation  
-
-
-
engine running, the vehicle has been  
stationary for more than fifteen minutes,  
the ignition has been switched off for a few  
minutes,  
the driver's seat belt is unfastened and their  
door is open.  
The system is activated or deactivated via the  
vehicle configuration menu.  
F
In the Driving/Vehicle menu  
of the touch screen, select the  
"Vehicle settings" tab then  
"Safety" and activate/deactivate  
"Fatigue detection".  
Malfunction  
In the event of a fault with the  
system, you are alerted by the  
illumination of this warning lamp,  
accompanied by the display of a  
message and an audible signal.  
As soon as the vehicle's speed drops  
below 40 mph (65 km/h), the system goes  
into standby.  
Driving time monitoring resumes when the  
vehicle travels at above 40 mph (65 km/h).  
Driving time warning  
Contact a CITROËN dealer or a qualified  
workshop to have the system checked.  
The system triggers an alert once it  
detects that the driver has not taken  
a break after two hours of driving at  
a speed above 40 mph (65 km/h).

Driving  
The driver is then alerted by the message  
"Take care!", accompanied by an audible  
signal.  
Driver inattention alert  
The following situations may interfere with  
the operation of the system or prevent it  
working:  
After three first level alerts, the system triggers  
a new alert with the message "Take a break!",  
accompanied by a more pronounced audible  
signal.  
-
poor visibility (inadequate lighting of  
the roadway, falling snow, heavy rain,  
dense fog, etc.),  
dazzle (headlamps of an oncoming  
vehicle, low sun, reflections on a damp  
road, leaving a tunnel, alternating  
shade and light, etc.),  
windscreen area located in front of the  
camera: dirty, misted up, frost-covered,  
snow-covered, damaged or covered by  
a sticker,  
lane markings absent, worn, hidden  
(snow, mud) or multiple (roadworks,  
etc.),  
-
In certain driving conditions (poor road  
surface or strong winds), the system may  
give alerts independent of the driver's  
level of vigilance.  
-
-
Using a camera placed at the top  
of the windscreen, the system  
assesses the driver's level of  
vigilance by identifying variations  
in trajectory compared to the lane  
markings.  
-
-
close to the vehicle ahead (lane  
markings not detected),  
roads that are narrow, winding, etc.  
6
This system is particularly suited to fast roads  
(speed higher than 40 mph (65 km/h)).  
When the system interprets the behaviour of  
the vehicle as indicating a certain fatigue or  
inattention threshold on the part of the driver, it  
triggers the first level of alert.
