Rear Parking Sensors; Visual Assistance - CITROËN C4 Picasso Owner's Handbook Manual

Parking sensors
This system indicates the proximity of an
obstacle (person, vehicle, tree, gate, etc.) which
comes within the field of detection of sensors
located in the bumper.
Certain types of obstacle (stake, roadworks
cone, etc.) detected initially will no longer be
detected at the end of the manoeuvre due to
the presence of blind spots.
This function cannot, in any
circumstances, take the place of the
vigilance and responsibility of the driver.

Rear parking sensors

The system is switched on by engaging reverse
gear. This is accompanied by an audible signal.
The system is switched off when you exit
reverse gear.
Audible assistance
The proximity information is given by an
intermittent audible signal, the frequency of which
increases as the vehicle approaches the obstacle.
The sound emitted by the speaker (right or left)
indicates the side on which the obstacle is located.
When the distance between the vehicle and
the obstacle becomes less than approximately
thirty centimetres, the audible signal becomes
continuous.

Visual assistance

This supplements the audible signal by
displaying bars in the screen or the instrument
panel which move progressively nearer to
the vehicle. When the obstacle is near, the
"Danger" symbol is displayed.
