Rear parking sensors
System consisting of four proximity sensors, located in the rear bumper. This detects any obstacle (person, vehicle, tree, gate, etc.) behind the vehicle, except obstacles located just below the bumper.
An object, such as a stake, a roadworks cone or any other similar object may be detected at the beginning of the manoeuvre, but may no longer be detected when the vehicle comes close to it.
The parking sensor system cannot, in any circumstances, take the place of the vigilance and responsibility of the driver.
The system is activated as soon as reverse gear is engaged, accompanied by an audible signal. The proximity information is given by: - an audible signal, which becomes more
rapid as the vehicle approaches the obstacle. - a graphic on the multifunction screen, with
blocks which become increasingly closer to the vehicle.
Activation
When the distance between the rear of the vehicle and the obstacle is less than thirty centimetres, t he audible signal becomes continuous and the "Danger" symbol appears on the multifunction screen. On completion of the manoeuvre, when you exit reverse gear, the system becomes inactive.

Programming Operating faults
If there is an operating fault, when reverse gear is engaged this warning lamp comes on on the instrument panel, accompanied by an audible signal (shor t beep) and a message on the multifunction screen.
You can activate or deactivate the system by means of the multifunction screen configuration menu. The system state is memorised when switching off the ignition. For more information on access to the parking assistance menu, refer to vehicle configuration in the "Multifunction screens" section corresponding to your screen.
The system will be deactivated automatically when towing a trailer or when a bicycle carrier is fitted (vehicle fitted with a towbar or bicycle carrier recommended by CITROËN).
In bad or wintry weather, ensure that the sensors are not covered with mud, frost or snow.
