obstacle (person, vehicle, tree, gate, etc.) which comes within the field of detection of sensorslocated in the bumper.
Cer tain types of obstacle (stake, roadworkscone, etc.) detected initially will no longer bedetected at the end of the manoeuvre due to
the presence of blind spots.


Audible assistance

The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than approximatelythirty centimetres, the audible signal becomes continuous.
The s
ystem is switched on by engaging reversegear. This is accompanied by an audible signal.

is engaged this lamp in the button flashes,
accompanied by an audible signal.This supplements the audiblesignal by displaying bars in the screen, in front of or behind the
vehicle.If one of the sensors is fault
y, it

screen.
Contact a CITROËN dealer or a
qualified
workshop. Th
ese bars flash at the start of the manoeuvrethen become fixed from a certain distance between the vehicle and the obstacle.
