When starting the vehicle, the warning lamp  
comes on in each mirror to indicate that the  
system is activated.  
Deactivation / Activation  
The state of the system stays in the memory when  
switching off the ignition.  
The system is automatically deactivated  
when towing with a towing device  
approved by the Manufacturer.  
This system includes sensors, placed on the  
sides of the bumpers, and warns the driver of the  
potentially dangerous presence of another vehicle  
(car, truck, motorcycle) in the blind spot areas of  
their vehicle (areas hidden from the driver's field  
of vision).  
Conditions for operation  
►ꢀ Press this button to deactivate / reactivate  
the system at any time.  
– All vehicles are moving in the same direction  
and in adjacent lanes.  
Deactivation is signalled by the lighting of  
the indicator lamp in the button and this  
warning lamp in the instrument panel.  
The system is automatically reactivated every  
time the ignition is switched on.  
– 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).  
– 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.  
– Overtaking a vehicle over a certain period of  
time and the vehicle being overtaken remains in  
the blind spot.  
– You are driving on a straight or slightly curved  
road.  
Malfunction  
In the event of a system  
malfunction, these warning lamps  
come on on the instrument panel, accompanied  
by an onscreen message and an audible signal.  
Have the system checked by a dealer or a  
qualified workshop.  
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.  
Blind Spot Detection  
Refer to the General recommendations on the use  
of driving and manoeuvring aids.  
Activation / Deactivation  
– Your vehicle is not pulling a trailer, a caravan,  
etc.  
It is set via the Driving / Vehicle touch  
screen menu.

– In the presence of non-moving objects (parked  
vehicles, barriers, street lamps, road signs, etc.).  
– Oncoming traffic.  
– Driving on a winding road or a sharp corner.  
– When overtaking or being overtaken by a very  
long vehicle (lorry, bus, etc.) that is detected  
in the rear blind spot but is also present in the  
driver’s front field of vision.  
Take care not to cover the warning zone in  
the door mirrors or the detection zones on the  
front and rear bumpers with adhesive labels  
or other objects; they may hamper correct  
operation of the system.  
Operating limits  
Active Blind Spot  
Detection  
– When overtaking quickly.  
– In very heavy traffic: vehicles detected in  
front and behind are confused with a lorry or a  
stationary object.  
– If the Park Assist or DS PARK PILOT function is  
activated.  
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 attempt to cross  
a lane marking with the direction indicator  
activated, to help you avoid a collision.  
This system is the combination of the Active  
Lane Departure Warning System and Blind Spot  
Detection.  
Malfunction  
If the event of malfunction, this warning  
lamp comes on in the instrument panel,  
accompanied by the display of a message.  
Contact a dealer or a qualified workshop to have  
the system checked.  
These two functions must be activated and in  
operation.  
The speed of the vehicle must be between 40 and  
87 mph (65 and 140 km/h).  
These functions are especially suitable for driving  
on motorways and main roads.  
For more information on the Active Lane  
Departure Warning System and Blind Spot  
Detection, refer to the corresponding sections.  
The system may suffer temporary  
interference in certain weather conditions  
(rain, hail, etc.).  
In particular, driving on a wet surface or  
moving from a dry area to a wet area can  
cause false alerts (for example, the presence  
of a fog of water droplets in the blind spot  
angle is interpreted as a vehicle).  
In bad or wintry weather, ensure that the  
sensors are not covered by mud, ice or snow.  
No alert is triggered in the following conditions:
