CITROEN C3 Handbook page 117

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, which is confirmed by an audible signal.
The system is switched off when disengaging
reverse gear.
Audible assistance
The system signals the presence of obstacles
within the sensors' detection zone.
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 about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
Visual assistance
This supplements the audible signal by
displaying bars on the screen that represent the
distance between the obstacle and the vehicle
(white: more distant, orange: close, red: very
close).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
In addition to the rear parking sensors, the front
parking sensors are triggered when an obstacle
is detected in front and the speed of the vehicle
is still below 6 mph (10 km/h).
The front parking sensors are interrupted if the
vehicle stops for more than three seconds in
forward gear, if no further obstacles are detected
or when the speed of the vehicle exceeds 6 mph
(10 km/h).
The sound emitted by the speaker (front
or rear) indicates whether the obstacle is
in front or behind.
