This system is the combination of the Active  
Lane Departure Warning System and Blind Spot  
Detection.  
These two functions must be activated and in  
operation.  
This is confirmed by an audible signal.  
The system is switched off when you come out of  
reverse gear.  
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.  
Audible assistance  
The speed of the vehicle must be between 40 and  
87 mph (65 and 140 km/h).  
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.  
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.  
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 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.  
Parking sensors  
Refer to the General recommendations on the use  
of driving and manoeuvring aids.  
Depending on version, in the example shown, only  
the obstacles present in the shaded area will be  
signalled by the audible assistance.  
The proximity information is given by an  
intermittent audible signal, the frequency of  
which increases as the vehicle approaches the  
obstacle.  
Active Blind Spot  
Detection  
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.  
Using sensors located in the bumper, this  
system signals the proximity of obstacles  
(e.g. pedestrian, vehicle, tree, barrier) present in  
their field of detection.  
Rear parking sensors  
The system is switched on by engaging reverse  
gear.  
When the distance between the vehicle and  
the obstacle becomes less than about thirty
