diagram, which enables them to monitor this  
information in real time.  
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.  
accompanied by the display of a message and an  
audible signal.  
Contact a dealer or a qualified workshop.  
The system is activated at speeds above  
16 mph (25 km/h).  
This system is particularly useful on motorways  
and main roads.  
Active lane departure  
warning system  
The following situations may interfere  
with the operation of the system or  
prevent it from working:  
For more information, refer to the General  
recommendations on the use of driving  
and manoeuvring aids.  
– system’s camera field of vision blocked or  
obstructed.  
– wearing certain types of spectacles or  
sunglasses that are very dark or reflective.  
– face partially obscured (e.g. by a hand, by  
hair).  
The system corrects the vehicle's trajectory by  
alerting the driver as soon as it detects a risk of  
involuntary lane departure or crossing of a verge  
or hard shoulder (depending on version).  
To do this, the system uses a camera, placed on  
the upper part of the windscreen, identifying the  
lane markings on the ground and the side of the  
road (depending on version).  
Activation/Deactivation  
The settings are changed via the Driving/  
Vehicle touch screen menu.  
– unusual or incorrect driving position.  
Under no circumstances shall the  
Manufacturer be held liable in the event of  
alerts not being given or for the consequences  
of using this system.  
The status of the system stays in the memory  
when switching off the ignition.  
Detection  
If an unexpected change of direction is  
detected, this warning lamp flashes in the  
instrument panel accompanied by an audible  
signal.  
This system is particularly useful on motorways  
and main roads.  
Lane departure warning  
system  
No warning is transmitted while the direction  
indicator is activated and for approximately 20  
seconds after the direction indicator is switched  
off.  
For more information, refer to the General  
recommendations on the use of driving  
and manoeuvring aids.  
Operating conditions  
– Vehicle speed between 43 and 112 mph (70 and  
Malfunction

solid or broken lines, detects the involuntary

firmly holding the steering wheel  
(e.g. during an emergency manoeuvre).  
The correction is interrupted immediately if  
the direction indicators are operated.  
As soon as the system identifies a risk of  
involuntarily crossing one of the lane markings  
detected on the ground or a lane boundary  
(e.g. grass verge), it performs the trajectory  
correction necessary to restore the vehicle to its  
original lane.  
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 braking.  
While the direction indicators are activated and  
for a few seconds after switching them off, the  
system considers that a change of trajectory is  
intentional and no correction is triggered during  
this period.  
The driver will notice a turning movement of the  
steering wheel.  
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).  
This warning lamp flashes during  
trajectory correction.  
Driving situations and related alerts  
The table below describes the alerts and messages displayed in different driving situations.  
The actual order of display of these alerts may be different.

Comments  
The system corrects the trajectory on the side where the risk of line crossing is detected.  
The driver's hands are on the steering wheel.  
ON  
If, while correcting the trajectory, the system determines that the correction will not be  
enough and that a solid line will be crossed: 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.  
"Hold the steering 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.  
The following situations may interfere  
with the operation of the system or  
prevent it from working:  
– Towing or with a bicycle carrier on a towing  
device, especially with trailer not plugged in or  
not approved.  
Operating limits  
The system goes into standby automatically in  
the following cases:  
– Insufficient contrast between the road  
surface and the verge or hard shoulder  
(e.g. shade).  
– Road in poor condition, unstable or with very  
poor grip (risk of aquaplaning, snow, ice).  
– Adverse weather conditions.  
– ESC deactivated or operation triggered.  
– Speed below 43 mph (70 km/h) or greater than  
112 mph (180 km/h).  
– Lane markings worn, hidden (snow, mud) or  
multiple (roadworks, etc.),  
– Driving on racing circuits.  
– Electrical connection to a trailer.  
– Use of a"space-saver" spare wheel detected (as  
detection is not immediate, deactivation of the  
system is recommended).  
– Driving on a rolling road.  
– Close proximity to the vehicle in front (lane  
markings may not be detected).  
– Roads that are narrow, winding.  
Deactivation/Activation  
– Dynamic driving style detected, pressure on the  
brake or accelerator pedal.  
Risk of undesirable operation  
– Driving over lane markings.  
– Activation of the direction indicators.  
– Crossing the inside line on a bend.  
– Driving on a tight bend.  
The system should be deactivated in the following  
situations:  
– When changing a wheel or working near a  
wheel.  
– Inactivity by the driver detected during  
correction.

This system warns the driver of a potential  
danger posed by the presence of another vehicle  
(car, lorry, motorcycle) in the vehicle's blind  
spots (areas hidden from the driver's field of  
vision) using sensors located on the sides of the  
bumpers.  
Operating conditions  
– All vehicles are moving in the same direction  
Deactivation is signalled by the lighting of  
the indicator lamp in the button and this  
warning lamp on the instrument panel.  
The state of the system is stored when the  
ignition is switched off.  
and in adjacent lanes.  
– The speed of your vehicle must be between  
7 and 87 mph (12 and 140 km/h) (versions without  
Park Assist or DS PARK PILOT) or between 19 and  
87 mph (30 and 140 km/h) (versions with Park  
Assist or DS PARK PILOT).  
Malfunction  
– When overtaking a vehicle, the speed  
difference is less than 6 mph (10 km/h).  
– When overtaken by a vehicle, the speed  
difference is less than 16 mph (25 km/h).  
– Traffic is flowing normally.  
In the event of a malfunction, these  
warning lamps light up on the  
instrument panel, accompanied by the display of  
a message and an audible signal.  
Have it checked by a dealer or a qualified  
workshop.  
– Overtaking a vehicle over a certain period of  
time and the vehicle being overtaken remains in  
the blind spot.  
The warning is given by a fixed warning lamp that  
appears in the door mirror on the side in question:  
– immediately, when being overtaken;  
– after a delay of about one second, when  
overtaking a vehicle slowly.  
– You are driving on a straight or slightly curved  
road.  
Blind spot monitoring  
– Your vehicle is not pulling a trailer, a caravan,  
etc.  
For more information, refer to the General  
recommendations on the use of driving  
and manoeuvring aids.  
Activation/Deactivation  
It is set via the Driving/Vehicle touch  
screen menu.  
When starting the vehicle, the warning lamp  
comes on in each mirror to indicate that the  
system is activated.  
The status of the system is memorised when the  
ignition is switched off.  
The system is automatically deactivated  
when towing with a towing device  
approved by the Manufacturer.
