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.
Deactivation / Activation of the
front and rear parking sensors
The parking sensors can be deactivated in the
touch screen tablet.
F Select the "Driving assistance" menu.
F Press on "Parking sensors".
The indicator lamp in the button
comes on.
Pressing this button again reactivates the
system. The indicator lamp goes off.
The system will be deactivated
automatically if a trailer is being
towed or a bicycle carrier is fitted on
a towbar (vehicle fitted with a towbar
installed in line with the manufacturer's
recommendations).
The parking sensors are deactivated
while the Park Assist system is
measuring a space.
See the "Park Assist" section.
Operating fault
In the event of a malfunction of
the system, when reverse gear is
engaged the symbol for the button
changes to alert mode and the
warning lamp flashes for a few
moments then stays on continuously.
A message appears, accompanied by an
audible signal (short beep).
Contact a CITRoËn dealer or a qualified
workshop.
In bad weather or in winter, ensure
that the sensors are not covered with
mud, ice or snow. When reverse gear is
engaged, an audible signal (long beep)
indicates that the sensors may be dirty.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals of the parking
sensor system.
High pressure jet wash
When washing your vehicle, do not
direct the lance within 30 cm of the
sensors.
