Malfunction  
This warning lamp lights up on the  
instrument panel, if the automatic braking  
system is reduced or degraded.  
With MyCitroën Drive Plus  
For more information, refer to the  
General recommendations on the use  
of driving and manoeuvring aids.  
The settings are changed via the ADAS  
touch screen application.  
This is a normal behavior, which does not  
request the support of a qualified workshop.  
This may be caused by a reduced visibility  
(e.g. rain, fog, snow, blinding by low sun) or by  
a real sensor blockage. In this case, stop the  
vehicle and verify if the front camera or the front  
radar is covered by dirt, snow, ice or anything  
preventing the sensing.  
In the event of a malfunction, this warning  
lamp lights up on the instrument panel,  
accompanied by the display of a message and  
an audible signal.  
Coffee Break Alert  
Depending on version, the function consists of  
either the "Coffee Break Alert" system alone or  
combined with the "Driver Attention Warning"  
system.  
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.  
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.  
Have it checked by a CITROËN dealer or a  
qualified workshop.  
If these warning lamps come on  
Activation/Deactivation  
By default, the function is automatically activated  
at every engine start.  
after the engine has been switched  
off and then restarted, contact a CITROËN  
dealer or a qualified workshop to have the  
system checked.  
– The driver's seat belt is unfastened and their  
door is opened.  
These warning lamps light up on  
the instrument panel and/or in the

Driving  
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).  
After three first-level alerts, the system triggers  
a further alert with the message "Driving at  
risk: Take a break", accompanied by a more  
pronounced audible signal.  
This system detects and signals the proximity of  
obstacles (e.g. pedestrian, vehicle, tree, barrier)  
using sensors located in the bumper.

Rear parking sensors  
In certain driving conditions (poor road  
surface or strong winds), the system may  
give alerts independent of the driver's level of  
vigilance.  
► Engage reverse gear to start the system  
(confirmed by an audible signal).  
The system is switched off when reverse gear is  
disengaged.  
Driver Attention Warning  
Depending on version, the Coffee Break Alert  
system may be combined with the Driver  
Attention Warning system.  
The following situations may interfere  
with the operation of the system or  
prevent it from working:  
Audible assistance  
– 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.  
The system signals the presence of obstacles  
which are both within the sensors’ detection zone  
and in the vehicle path defined by the direction of  
the steering wheel.  
The proximity information is given by an  
intermittent audible signal, the frequency of  
which increases as the vehicle approaches the  
obstacle.  
Parking sensors  
For more information, refer to the  
General recommendations on the use  
of driving and manoeuvring aids.  
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.  
When the distance between the vehicle and  
the obstacle becomes less than about thirty  
centimetres, the audible signal becomes  
continuous.  
The sound emitted by the speaker (right or  
left) indicates the side on which the obstacle is  
located.
