Driving  
This alert is issued via the display of  
Active Blind Spot  
Monitoring System  
These systems cannot in any circumstances  
replace the need for vigilance on the part  
of the driver who must remain in control  
of their decisions. In no case can these  
systems keep the driver awake or prevent  
them from falling asleep at the wheel.  
It is the driver's responsibility to stop if they  
feel tired.  
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.  
(depending on version)  
In addition to the fixed warning lamp in the door  
mirror on the side in question, a correction of  
trajectory will be felt if you cross a lane marking  
with the direction indicators on, to help you  
avoid a collision.  
The system resets itself if one of the following  
conditions is met:  
-
-
-
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 open.

Driving  
After three first level alerts, the system triggers  
a new alert with the message "Take a break!",  
accompanied by a more pronounced audible  
signal.  
Clean the windscreen regularly,  
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.  
Do not allow snow to accumulate on the  
bonnet or roof of the vehicle as this could  
conceal the detection camera.  
In certain driving conditions (poor road  
surface or strong winds), the system may  
give alerts independent of the driver's  
level of vigilance.  
Clean the front bumper, especially around  
the radar, removing mud, snow, etc.  
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.  
The following situations may interfere with  
the operation of the system or prevent it  
working:  
-
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.),  
Parking sensors  
This system is particularly suited to fast roads  
(speed higher than 40 mph (65 km/h)).  
-
-
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.),  
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.  
The driver is then alerted by the message  
"Take care!", accompanied by an audible  
signal.  
-
-
close to the vehicle ahead (lane  
markings not detected),  
roads that are narrow, winding, etc.  
Using sensors located in the bumper, this  
function warns of the proximity of obstacles  
(e.g. pedestrian, vehicle, tree, barrier) entering  
their field of detection.
