Driving -> Active Lane Departure Warning System for Your DS 3 Crossback 4 Door First Generation (2018-2022)

Driving

The system must not be activated in the  
following situations:  
The driver will notice a turning movement of the  
steering wheel.  
– Driving with a "space-saver" type spare  
wheel.  
This warning lamp flashes during  
trajectory correction.  
– When towing, especially with an  
unconnected or unapproved trailer.  
– Poor weather conditions.  
– Driving on slippery road surfaces (risk of  
aquaplaning, snow, ice).  
The driver can prevent the correction by  
keeping a firm grip on the wheel (during  
an avoiding manoeuvre, for example).  
The correction is interrupted immediately if  
the direction indicators are operated.  
Conditions for operation  
– Vehicle speed between 40 and 112 mph (65 and  
180 km/h).  
– Driving on racing circuits.  
– Driving on a rolling road.  
– Road marked with a central dividing line.  
– Steering wheel held in both hands.  
– Direction indicators not activated.  
– ESC system activated and operational.  
Malfunction  
A system malfunction is indicated  
by the Service warning lamp coming  
The system helps the driver only if there is  
a risk of the vehicle unintentionally  
wandering from the lane it is being driven in. It  
does not manage the safe driving distance,  
vehicle speed or brakes.  
on and this (orange) symbol, accompanied by an  
alert message and an audible signal.  
The driver must hold the steering wheel with  
both hands in a way that allows control to  
be maintained in circumstances where the  
system is not able to intervene (for example, if  
the central dividing line disappears).  
While the direction indicators are on and for  
a few seconds after switching them off, the  
system considers that any change of trajectory is  
intentional and no correction is triggered during  
this period.  
Active Lane Departure  
Warning System  
Refer to the General recommendations on the use  
of driving and manoeuvring aids.  
Using a camera located at the top of the  
windscreen to identify lane markings on the  
road and at the edges of the road (depending on  
version), the system corrects the trajectory of the  
vehicle while alerting the driver if it detects a risk  
of unintentionally crossing a line or hard shoulder  
(depending on version).  
However, with the Blind Spot Detection system  
activated, if the driver starts changing lanes and  
another vehicle is detected in the vehicle's blind  
spot, the system will correct the trajectory even  
though the direction indicators are on.  
Operation  
Once the system identifies a risk of the vehicle  
involuntarily crossing one of the lane markings  
detected or a lane limit (e.g. grass border), it  
makes the necessary trajectory correction to  
return the vehicle to its initial path.  
For more information on the Blind Spot Detection,  
refer to the corresponding section.  
This system is particularly useful on motorways  
and main roads.

If the system detects that the driver is not  
holding the wheel firmly enough during an  
automatic correction of trajectory, it interrupts  
the correction. An alert is triggered to  
encourage the driver to take back control of  
the vehicle.  
Driving situations and related alerts

Comments  
The system corrects the trajectory on the side where the  
risk of unintentional crossing is detected (orange line).  
(orange)/(green)  
ON  
– If, while correcting the trajectory, the system determines  
that the correction will not be enough and that a solid line  
will be crossed (orange line): the driver is warned that they  
must provide additional trajectory adjustment.  
– If the steering wheel is not held properly, an audible  
warning sounds, accompanied by a message, until the  
trajectory correction is completed or the driver has grasped  
the steering wheel correctly.  
(orange)/(green)  
"Hold the wheel"  
The duration of audible warnings will increase if multiple  
corrections are performed in quick succession. The warning  
will become continuous, persisting until the driver responds.  
– activation of the direction indicators,  
– crossing the inside line on a bend,  
– driving in a tight corner,  
– inactivity by the driver detected during  
correction.  
– running close to the vehicle in front (the lane  
markings may not be detected),  
– roads that are narrow, winding, etc.  
Operating limits  
The system goes into standby automatically in  
the following cases:  
– ESC deactivated or operation triggered,  
– speed below 40 mph (65 km/h) or greater than  
112 mph (180 km/h),  
– electrical connection of a trailer,  
– use of the "space-saver" spare wheel detected  
(as detection is not immediate, deactivation of  
the system is recommended),  
Risk of undesirable operation  
We recommend deactivating the system in the  
following driving situations:  
– driving on damaged, unstable or very slippery  
(ice) road surfaces,  
– unfavourable weather conditions,  
The following situations may interfere  
with the operation of the system or  
prevent it from working:  
– insufficient contrast between the road  
surface and the shoulders (e.g. shade),  
– lane markings worn, hidden (snow, mud) or  
multiple (roadworks, etc.),  
– dynamic driving style detected, pressure on the  
brake or accelerator pedal,  
– driving on a speed circuit,  
– driving on a rolling road.  
– driving where there are no lane markings,
